Design: The investigation comprised three studies. Study 1 evaluated calibration accuracy across four Samsung S5301 smartphones (Android v4.0.4) using commercial Sennheiser HD202 headphones. Study 2 involved referencing smartphone microphone sensitivity to narrowband noise intensity as measured in octave bands by a sound-level meter between 30 and 75 dB SPL (5 dB increments). Study 3 compared screening outcomes of smartphone based and conventional hearing screening. Study sample: Study 2: 15 normal-hearing subjects (age range, 18-22 years; all female). Study 3: 162 children (324 ears) aged 5 to 7 years. Results: Smartphone calibration at 20, 30, and 40 dB was within 1 dB of recommended reference equivalent thresholds levels. Microphone calibration for noise monitoring had maximum variability across phones of 0.9, 0.6, and 2.9 dB at 1, 2, and 4 kHz, respectively, from reference intensities (30 to 75 dB SPL). Screening outcomes demonstrated no significant difference between smartphone and conventional audiometry with an overall referral rate of 4.3% and 3.7%, respectively. Conclusions: The newly developed smartphone application can be accurately calibrated for audiometry with valid real-time noise monitoring, and clinical results are comparable to conventional screening.

Design: All participants were asked to complete the Attitudes toward Teleaudiology Scale for Practitioners (ATS-P), a 46-item online survey designed for this study. Study sample: The responses from 202 hearing healthcare practitioners working in Canada were collected. The sample consisted of 152 audiologists, 49 hearing instrument specialists, and one who did not specify a category. Results: The majority of respondents indicated that teleaudiology is likely to have a minimal effect on the quality of hearing healthcare in audiology and the quality of client-practitioner interactions, although many respondents indicated that teleaudiology would have a positive effect on accessibility to service. Nevertheless, a small minority of respondents indicated that teleaudiology would have a negative impact on quality of care in audiology. Conclusions: Willingness to use teleaudiology depended on a combination of the clinical tasks to be performed and the patient populations to be served. These findings can help guide the successful implementation of teleaudiology services. C1 [Singh, Gurjit; Boretzki, Michael; Launer, Stefan] Phonak AG, Stafa, Switzerland.

TI 'Getting used to' hearing aids from the perspective of adult hearing-aid users SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aids; focus group; adjustment to hearing aids ID HELP-SEEKING; ACCLIMATIZATION; IMPAIRMENT AB Objective: To describe getting used to hearing aids from the perspective of adult hearing-aid users. Design: Three focus group discussions were carried out. A topic guide and discussion exercises were used to elicit views on getting used to hearing aids. Discussion was audio recorded, transcribed verbatim, and subjected to qualitative content analysis. Study sample: Adult hearing aid users (n = 16). Results: Participants described getting used to hearing aids as a multi-factorial process which included adjusting to altered sensory input, practical matters such as cleaning and maintenance, and managing the psychosocial impact of hearing-aid use, such as on self-image. Users reported a process of discovering benefits and limitations of hearing aids leading to individual patterns of use that was relatively independent of input from audiologists. Conclusions : Getting used to hearing aids is a challenging multi-factorial process with both psychosocial and practical difficulties besides demands of adjusting to hearing-aid input.

This strategy is expected to provide more selective excitation of the cochlear apex, compared to a standard strategy where the lowest-frequency channel is conveyed by symmetric pulses in monopolar mode. In both strategies all other channels were conveyed by monopolar stimulation. Design: Within-subjects comparison between the two strategies. Four experiments: (1) discrimination between the strategies, controlling for loudness differences, (2) consonant identification, (3) recognition of lowpass-filtered sentences in quiet, (4) sentence recognition in the presence of a competing speaker. Study sample: Eight users of the Advanced Bionics CII/Hi-Res 90k cochlear implant. Results: Listeners could easily discriminate between the two strategies but no consistent differences in performance were observed. Conclusions: The proposed method does not improve speech perception, at least in the short term.

TI Repeatability of sound-evoked triceps myogenic potentials SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Balance assessment; tVEMP; sensory feedback; vestibulospinal reflex; electromyography (EMG) ID GALVANIC VESTIBULAR STIMULATION; BONE CONDUCTED VIBRATION; TEST-RETEST RELIABILITY; HEALTHY-SUBJECTS; RESPONSES; AGREEMENT; AFFERENTS; MUSCLES; OTOLITH; REFLEX AB Objective: To investigate the repeatability of sound-evoked vestibular evoked myogenic potentials recorded from the triceps (tVEMPs) with and without visual feedback. Design: tVEMP responses to 95 dB nHL 500-Hz tone bursts were recorded in a longitudinal, repeated measures study where P1 and N1 latencies and amplitudes were measured on three separate occasions from the same individuals. Analysis of variance, intra-class correlations, and limits of repeatability analyses were used to assess tVEMP repeatability and effects of visual feedback. Study sample: Fifteen participants (nine women) aged between 18 and 41 years took part. Results: Response rates of 63% and 68% were obtained for tVEMPs with eyes open and closed, respectively. When present, tVEMP latencies and amplitudes exhibited fair to good repeatability. Repeatability of tVEMP latencies and amplitudes measured using Bland-Altman methods was poorer with eyes closed. Conclusions: Sound-evoked tVEMP response rates are too low to support their clinical utility at the moment. tVEMP response rate may be improved by refi ning the balance task to include a force related target. Better tVEMP repeatability with eyes open supports the hypothesis that the response is modulated by visual feedback, and is consistent with studies reporting triceps responses to galvanic stimulation.

TI Clinical feasibility of fast psychophysical tuning curves evaluated using normally hearing adults: Success rate, range of tip shift, repeatability, and comparison of methods used for estimation of frequency at the tip SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Dead regions; psychophysical tuning curves; repeatability ID COCHLEAR DEAD REGIONS; ARTICULATION INDEX PREDICTIONS; THRESHOLD-EQUALIZING NOISE; IMPAIRED LISTENERS; SELECTIVITY; DIAGNOSIS; CHILDREN; MASKING; INFORMATION; SPEECH AB Objective: Psychophysical tuning curves (PTCs) have been used predominantly in laboratory settings to assess frequency selectivity in the auditory system. Recently, a fast-PTC procedure has been developed for diagnosis of cochlear dead regions. In this study the clinical feasibility of using fast PTCs in adults was investigated. Success rate (the number of successes per number of attempts) and repeatability were assessed. The range of the tip frequency (f(tip)) shift was established and different methods of f(tip) estimation compared. Design: Fast PTCs were measured for signal frequencies (f(s)) of 500, 1000, 2000, 3000, and 4000 Hz on two occasions using an upward-sweeping masker. Five methods were used to estimate f(tip) for each PTC. Study sample: Thirty-two adults with normal hearing were tested. Results: All participants were able to successfully complete the task, the majority of them with minimal training. The moving average, quadratic function, and double lowpass filtering methods had the highest success rate in f(tip) estimation. The quadratic function method had the smallest 95% range of - 3.4% f(s) to 10.2% f(s) and the best test-retest reliability of 5.1% f(s). Conclusions: Fast PTCs show potential for clinical use due to a high success rate with minimal training required. We suggest the quadratic function method for routine clinical use as it had the smallest 95% range, a high success rate in f(tip) estimation and the best test-retest reliability. For fast PTCs measured for signal frequencies from 500 to 4000 Hz using an upward-sweeping masker, we suggest the normative range of f(tip) to be - 3% f(s) to 10% f(s) with a test-retest reliability of 5% f(s).

Design: The speech reception thresholds (SRT) in noise were measured by means of an adaptive test procedure, and by measurement at various signal-to-noise ratios to determine the course of the entire discrimination function per subject. Study sample: The measurements were performed on 38 CI users fitted with a Cochlear (TM) Freedom (R) or a Cochlear (TM) Nucleus (R) 5 CI system. Results: The test-retest reproducibility showed a significant dependence on the SRT in noise. For the better performers, the test-retest difference was found to be smaller, while for the poorer performers the difference increased. For the better performers, the slope of the discrimination function at SRT (s50) was comparable to that for individuals with normal hearing, while for the poorer performers the s50 tended to be significantly reduced. Conclusions: As the CI users differed significantly in their SRT and their s50, a unified discrimination function for CI users must not be used. Further tailoring of the procedure may be required, especially for poorer CI performers. C1 [Hey, Matthias; Mueller-Deile, Joachim] KG Hanover, Cochlear Deutschland GmbH & Co, Hannover, Germany.

Study sample: The study participants used French as their home language, had completed an otolaryngology (ENT) assessment, and had sought help with disabling tinnitus. Results: No differences were found according to gender, age, or degree of hearing loss. The THI-FQ was very stable over a period of approximately 32 days. Internal consistency was 0.93 for the total score. Convergent validity with the TRQ was 0.81 (p < 0.001) while construct validity, as obtained with the BDI-II, was 0.74 (p < 0.001). As in other studies, the factor analysis did not confirm the structure proposed by Newman et al in the original study (1996). Conclusions: The THI-FQ presents very good reliability and validity, comparable to translations in other languages and the original version.

Design: A cross-sectional study was performed in 37 hospitals and mother-child clinics from different health sectors in Jordan. The hearing screening protocol was performed in three stages. Data collected as risk factors for infant hearing loss included those on the 2007 Joint Committee on Infant Hearing list as well as other factors believed to be possibly significant. Study sample: All babies born in or attending any of these hospitals or clinics were screened for hearing loss, which included a total of 63 041. Results: Of the 63 042 infants, 966 (1.5%) were confirmed to have significant hearing loss. We identified additional risk factors that were associated with hearing loss in infants. Conclusion: These preliminary data add to the understanding of the epidemiology of hearing loss in Jordan. The presence of at least one JCIH risk factor, admission to NICU for > 5 days, age, birth weight, postnatal hypoxia, and mode of delivery were independently associated with hearing loss.

Design: A qualitative study applying mainly focus-group methodology was applied. Study sample: Thirty-six Dutch and South African adults (>= 18 years of age) with HL (20-95 dB HL) who used oral communication as first communication. Summative content analysis was performed on the transcripts by linkage to appropriate ICF categories. Results: 143 ICF categories were identified, most of which belonged to the Activities & Participation (d) component, closely followed by the Environmental factors component. Participants specifically mentioned categories related to oral communication and interaction. Assistive technology (such as hearing aids), noise, and support by and attitudes of others in the environment of the participants were considered highly influential for functioning and disability. Conclusions: The present study illustrates the complex and encompassing nature of aspects involved in functioning and disability of adults with HL. Findings highlight the necessity of using a multidimensional tool, such as the ICF, to map functioning and disability with hearing loss, allowing consideration and evaluation of aspects that are both internal and external.

Design: Twelve MCL repetitions were measured within the ANL test using interleaved methodology during one session using a non-semantic version. Phonological (PWM) and visuospatial working memory (VSWM) was measured. Study sample: Thirty-two normal-hearing adults. Results: Repeated measures ANOVA, intraclass correlations, and the coefficient of repeatability (CR) were used to assess the repeatability. Repeated measures ANOVA and CR indicated poor agreement between the two first repetitions. After excluding the first repetition, analyses showed that the MCL in the ANL test is reliable. A negative association was found between PWM and MCL variability indicating that subjects with higher PWM show less variability. Conclusions: The findings suggest that, after excluding the first repetition, the MCL in the ANL test is reliable. A single repetition of the MCL in the ANL test should be avoided. If an interleaved methodology is used, a single ANL repetition should be added prior to the actual testing. The findings also suggest that MCL variability is associated to PWM but not VSWM.

TI Associations between dietary quality, noise, and hearing: Data from the National Health and Nutrition Examination Survey, 1999-2002 SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Demographics/epidemiology; hearing conservation; noise; pharmacology ID TEMPORARY THRESHOLD SHIFT; NEWLY INDEPENDENT STATES; US GENERAL-POPULATION; ORAL MAGNESIUM INTAKE; SOUTH-EASTERN EUROPE; ACETYL-L-CYSTEINE; IMPULSE-NOISE; D-METHIONINE; OLDER-ADULTS; RISK-FACTORS AB Objective: A statistically significant relationship between dietary nutrient intake and threshold sensitivity at higher frequencies has been reported, but evidence conflicts across studies. Here, the potential interaction between noise and diet in their association to hearing was examined. Design: This cross-sectional analysis was based on Healthy Eating Index data and audiological threshold pure-tone averages for low (0.5 to 2 kHz) and high (3 to 8 kHz) frequencies. Study sample: Data were drawn from the National Health and Nutrition Examination Survey, 1999-2002. Results: Controlling for age, sex, race/ethnicity, education, diabetes, hypertension, and smoking we found statistically significant relationships between dietary quality and high-frequency threshold sensitivity as well as noise exposure and high-frequency thresholds. In addition, there was a statistically significant interaction between dietary quality and reported noise exposure with respect to high-frequency threshold sensitivity in participants, where greater reported noise exposure and poorer diet were associated with poorer hearing (p's < 0.05). Conclusions: The current findings support an association between healthier eating and better hearing at higher frequencies; the strength of this relationship varied as a function of participant noise history, with the most robust relationship in those that reported military service or firearm use.

The aim of the present study was to evaluate the effectiveness of the TNF-alpha inhibitor etanercept applied after cochlear implantation trauma on the preservation of acoustic hearing. Design: Guinea pigs were randomly assigned to three groups receiving cochlear implantation trauma by cochleostomy. In one group, the site was sealed by bone cement with no further treatment. A second group was additionally implanted with an osmotic minipump delivering artificial perilymph into the scala tympani for seven days. In the third group, etanercept 1 mg/ml was added to artificial perilymph. Hearing was assessed by auditory brainstem responses at 2, 4, 6, and 8 kHz prior to and after surgery and on days 3, 5, 7, 14, 28. Study sample: Fifteen healthy guinea pigs. Results: The trauma led to threshold shifts from 50.3 dB +/- 16.3 dB to 68.0 dB +/- 19.3 dB. Hearing thresholds were significantly lower in etanercept-treated animals compared to controls on day 28 at 8 kHz and from day 3 onwards at 4 and 2 kHz (p < 0.01; two-way RM ANOVA / Bonferroni t-test). Conclusion: The application of etanercept led to preservation of acoustic hearing after cochlear implantation trauma.

TI Investigation into the applicability and optimization of the Dutch matrix sentence test for use with cochlear implant users SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech intelligibility; cochlear implant; matrix test; speech-in-noise test; speech reception threshold ID SPEECH RECEPTION THRESHOLD; IN-NOISE TESTS; NORMAL-HEARING; INTELLIGIBILITY TESTS; IMPAIRED LISTENERS; RECOGNITION; RELIABILITY; MULTICENTER; EQUIVALENCY; QUIET AB Objective: Matrix sentence tests use words from a fixed word matrix to compose syntactically equivalent, but semantically unpredictable sentences. These tests are suitable for monitoring performance of cochlear implant (CI) users by repeated speech intelligibility testing. This study evaluates the Dutch matrix sentence test in CI users in quiet and in noise. It then investigates the possibility to improve the test-retest reliability for CI users by selecting subsets of sentences. Design: Repeated speech intelligibility testing was performed in quiet and in noise. The effect of sentence selection on the test-retest reliability was predicted by computer simulations and experimentally evaluated using a cross-over design. Study sample: Fifteen post-lingually deafened CI users, of which eleven participated in the cross-over study. Results: The test-retest reliability equaled 2.3 dB in quiet and 1.3 dB in noise. The simulations predicted an improvement in test-retest reliability, especially in quiet. The cross-over study did not confirm the predictions. Conclusions: The results of the study suggest that the homogeneity of the sentences is not the prime component underlying the test-retest reliability. The Dutch matrix speech material and the selected subsets of sentences were equally suitable for speech intelligibility testing in CI users.

Design: A repeated measures quasi-experimental design was employed. Study sample: Thirty healthy newborns participated. ABRs were evoked using 60, 45, and 30 dB nHL air-conducted CE-Chirps and 45, 30, and 15 dB nHL bone-conducted CE-Chirps at a rate of 57.7/s. Measures were repeated by a second tester. Results: Statistically significant correlations (p < .0001) and predictive linear relations (p < .0001) were found between testers for wave V latencies and amplitudes to air-and bone-conducted CE-Chirps. There were also no statistically significant differences between testers with wave V latencies and amplitudes to air-and bone-conducted CE-Chirps (p < .05). As expected, significant differences in wave V latencies and amplitudes were seen as a function of stimulus intensity for air-and bone-conducted CE-Chirps (p < .0001). Conclusions: These results suggest that ABRs to air-and bone-conducted CE-Chirps can be reliably repeated in newborns with different testers. The CE-Chirp may be valuable for both screening and diagnostic audiologic assessments of newborns.

Design: Individualized computer models of normal and impaired hearing were constructed and evaluated using the psychophysical data obtained from human listeners. Computer models of impaired hearing were generated to reflect the hypothesized underlying pathology (e. g. dead regions, outer hair cell dysfunction, or reductions in endocochlear potential). These models were evaluated in terms of their ability to replicate the original patient data. Study sample: Auditory profiles were measured for two normal and five hearing-impaired listeners using a battery of three psychophysical tests (absolute thresholds, frequency selectivity, and compression). Results: The individualized computer models were found to match the data. Useful fits to the impaired profiles could be obtained by changing only a single parameter in the model of normal hearing. Sometimes, however, it was necessary to include an additional dead region. Conclusion: The creation of individualized computer models of hearing loss can be used to simulate auditory profiles of impaired listeners and suggest hypotheses concerning the underlying peripheral pathology.

The efficient utilization of the visual modality becomes increasingly important in difficult listening conditions, and especially for older and hearing-impaired listeners with sensory or cognitive decline. First, this report will quantify audiovisual integration skills using a recently developed capacity measure that incorporates speed and accuracy. Second, to investigate sensory factors contributing to integration ability, high and low-frequency hearing thresholds will be correlated with capacity, as well as gain measures from sentence recognition. Design: Integration scores were obtained from a within-subjects design using an open-set sentence speech recognition experiment and a closed set speeded-word classification experiment, designed to examine integration (i.e. capacity). Study sample: A sample of 44 adult listeners without a self-reported history of hearing-loss was recruited. Results: Results demonstrated a significant relationship between measures of audiovisual integration and hearing thresholds. Conclusions: Our data indicated that a listener's ability to integrate auditory and visual speech information in the domains of speed and accuracy is associated with auditory sensory capabilities and possibly other sensory and cognitive factors.

TI Adaptation to nonlinear frequency compression in normal-hearing adults: A comparison of training approaches SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory training; analytic; synthetic; passive exposure; frequency lowering ID SPEECH-RECOGNITION PERFORMANCE; SPECTRALLY SHIFTED SPEECH; R-VERTICAL-BAR; IMPAIRED LISTENERS; DISTORTED SPEECH; NOISE; PERCEPTION; TRANSPOSITION; DISCRIMINATION; CHILDREN AB Objective: To identify which training approach, if any, is most effective for improving perception of frequency-compressed speech. Design: A between-subject design using repeated measures. Study sample: Forty young adults with normal hearing were randomly allocated to one of four groups: a training group (sentence or consonant) or a control group (passive exposure or test-only). Test and training material differed in terms of material and speaker. Results: On average, sentence training and passive exposure led to significantly improved sentence recognition (11.0% and 11.7%, respectively) compared with the consonant training group (2.5%) and test-only group (0.4%), whilst, consonant training led to significantly improved consonant recognition (8.8%) compared with the sentence training group (1.9%), passive exposure group (2.8%), and test-only group (0.8%). Conclusions: Sentence training led to improved sentence recognition, whilst consonant training led to improved consonant recognition. This suggests learning transferred between speakers and material but not stimuli. Passive exposure to sentence material led to an improvement in sentence recognition that was equivalent to gains from active training. This suggests that it may be possible to adapt passively to frequency-compressed speech.

Design: Pure-tone air conduction thresholds were obtained in three conditions: (1) with a clinical audiometer in a quiet sound booth, (2) with the KUDUwave in a quiet sound booth, and (3) with the KUDUwave with 40 dBA of background noise. Study sample : A total of 31 individuals ranging in age from 15 to 80 years participated in the study, 21 with normal hearing and ten with hearing loss. Results: Eighty-nine percent of thresholds obtained with the KUDUwave in quiet, and 92% of thresholds obtained with the KUDUwave in background noise were within 5 dB of those obtained with the clinical audiometer. Accuracy was poorer at 250 Hz and 8000 Hz. Conclusion: Ambient noise typical of that found in a non-sound-treated room, did not affect the accuracy of air conduction hearing thresholds obtained with the KUDUwave. The KUDUwave may be a viable method of testing when a clinical audiometer and sound booth are not available.

Despite regulations and preventive measures, noise-induced hearing loss is common. The current reference test is pure-tone air-conduction audiometry (PTA), but this test cannot be used to detect early hearing loss. Objective: In this study, we assess one-day auditory fatigue using both PTA and efferent reflexes (ER) measured using DPOAEs associated with contralateral acoustic stimulation (CAS DPOAEs). Design: The noise exposure history, PTA, and ER detection were performed in seven different companies where the L-EX,L-8h was 85 dB(A). Hearing was tested before and at the end of the working day. Study sample: Forty-six volunteers were selected to carry out this study. Results: After a single working day, a greater impact of noise was measured using ER thresholds than PTA or DPOAEs. ER measurements are objective, easy to perform, and do not require a sound-attenuated booth. Conclusion: Screening workers by periodically measuring ER thresholds using CAS DPOAEs helps detect early changes in hearing status, before the onset of noise-induced hearing loss. These tests can be readily applied as part of a hearing conservation program.

Design: The TEN-test was carried out from 0.5 to 4 kHz and fast PTCs were carried out at >= 2 frequencies. Study sample: The TEN-test was completed on 70 ears; fast PTCs were measured on 20 ears. Results: TEN-test findings were repeatable in terms of meeting the criteria for a DR (97%) and identifying the same edge frequency (f(e)) (87%). In all cases, fast PTCs were repeatable in terms of meeting the criteria for DRs. There was 87% agreement between the two procedures in terms of the presence of off-frequency listening, and there was 73% agreement in terms of f(e). Fast PTCs had a 10% lower 'conclusive finding' rate than the TEN-test and the test duration was typically 40 minutes longer. Conclusions: Both the TEN-test and fast PTCs have high test-retest repeatability. The TEN-test is more clinically feasible due to its shorter test duration and higher interpretation rate, but it may underestimate the extent of a DR because of its inability to precisely identify f(e).

It is commonly believed that betahistine increases cochlear blood flow and thus decreases the endolymphatic hydrops that is the cause of Meniere's. Despite common clinical use, there is little understanding of the kinetics or effects of its metabolites. This study investigated the effect of the betahistine metabolites aminoethylpyridine, hydroxyethylpyridine, and pyridylacetic acid on cochlear microcirculation. Design: Guinea pigs were randomly assigned to one of the groups: placebo, betahistine, or equimolar amounts of aminoethylpyridine, hydroxyethylpyridine, or pyridylacetic acid. Cochlear blood flow and mean arterial pressure were recorded for three minutes before and 15 minutes after treatment. Study sample: Thirty Dunkin-Hartley guinea pigs assigned to one of five groups with six guinea pigs per group. Results: Betahistine, aminoethylpyridine, and hydroxyethylpyridine caused a significant increase in cochlear blood flow in comparison to placebo. The effect seen under aminoethylpyridin was greatest. The group treated with pyridylacetic acid showed no significant effect on cochlear blood flow. Conclusion: Aminoethylpyridine and hydroxyethylpyridine are, like betahistine, able to increase cochlear blood flow significantly. The effect of aminoethylpyridine was greatest. Pyridylacetic acid had no effect on cochlear microcirculation.

TI Development of a Dutch matrix sentence test to assess speech intelligibility in noise SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech-in-noise; speech test; speech intelligibility; normative data ID HEARING AB Objective: A Dutch matrix sentence test was developed and evaluated. A matrix test is a speech-in-noise test based on a closed speech corpus of sentences derived from words from fixed categories. An example is 'Mark gives five large flowers.' Design: This report consists of the development of the speech test and a multi-center evaluation. Study sample: Forty-five normal-hearing participants. Results: The developed matrix test has a speech reception threshold in stationary noise of -8.4 dB with an inter-list standard deviation of 0.2 dB. The slope of the intelligibility function is 10.2 %/dB and this is slightly lower than that of similar tests in other languages (12.6 to 17.1 %/dB). Conclusions: The matrix test is now also available in Dutch and can be used in both Flanders and the Netherlands.

Patients underwent interview, examination, and pure-tone audiometry. Study sample: Thirty cases were included. Eighteen (60%) were female. Mean age was 41.6 years. Results: There was a range of otological symptoms (mean 3.2 per patient), most commonly tinnitus which was present in 27 (90%), accompanied by diverse non-otological symptoms. Twenty-one (70%) had previous oto-pathology, 19 (63%) psychopathology, and five (17%) head injury. Examination was normal in 28 (93%), as was audiometry in 13 (43%). Eleven (50%) smoked. Hearing loss was not necessarily a feature. Conclusions: The condition known as 'acoustic shock' injury is a complex disorder producing a range of symptoms with psychological overlay. However, there is often little clinical evidence of pathology and it has not been adequately defined as yet. By further characterization, epidemiology and aetiology can be better understood.

Design: Prospective observational study using validated quantitative outcome measures and detailed patient narrative before and two months after patients were provided with bluetooth accessories. Study sample: Twelve patients with bilateral NHS hearing aids participated. They had a wide range of ages and hearing loss. Results: After two months, 10 patients reported substantial additional benefit and kept the accessories; two returned them for various reasons. Statistically significant changes were seen in two validated outcome measures: the Glasgow Hearing Aid Benefit Profile and the International Outcome Inventory - Hearing Aids, but not in the Speech, Spatial and Qualities of Hearing Scale. Two notable benefits were reported: some described hearing the emotion and mood in a voice for the first time; others were amazed to report an improved ability to hear film or to hold conversations over the telephone. Conclusions: The provision of bluetooth accessories can give additional reported benefit for some patients - we need better knowledge about who benefits, and whether further support/training to individuals would make a difference.

The purpose of this study was to document the prevalence of autism spectrum disorders (ASD) in children with permanent hearing loss, to describe the audiologic characteristics, and to examine clinical management. Design: Prospective data related to clinical characteristics of children identified with hearing loss and ASD were examined. A retrospective chart review was also conducted to explore clinical management and uptake of amplification. Study sample: The study included all children in one Canadian region identified with permanent hearing loss and followed from 2002-2010. Results: Of a total of 785 children with permanent hearing loss, 2.2% (n = 17) also received a diagnosis of ASD. The 13 boys and 4 girls presented with a range of audiologic profiles from unilateral to profound bilateral hearing loss. Four of five children with unilateral hearing loss experienced progression to bilateral loss. Amplification was recommended for all but one child and 9 of 16 children continued to use their hearing devices. Conclusions: The higher prevalence rate of ASD in this clinical population is consistent with previous reports. Our findings suggest that some children with autism can derive benefits from the use of amplification. C1 [Fitzpatrick, Elizabeth M.] Univ Ottawa, Fac Hlth Sci, Ottawa, ON K1H 8M5, Canada.

The aim of this study was to determine the long-term benefits of cochlear implantation for this clinical population. Design: The study involved a retrospective chart review. Study sample: The review identified 21 children with complex disabilities who had received cochlear implants in a pediatric center prior to 2004. Length of cochlear implant use was between 7.3 and 19.0 years. Long-term functional auditory abilities were assessed pre and post-operatively using measures appropriate to the child's level of functioning. Cognitive assessments and developmental data were also available for the children. Results: Children's long-term speech recognition outcomes depended highly on their developmental status. Children with severe developmental delay showed no open-set speech recognition abilities while children with mild to moderate delays achieved open-set scores ranging from 48 to 94% on open-set word testing. Five of 13 (38%) children with complex needs had discontinued use of their cochlear implant. Conclusions: Long-term speech recognition abilities following cochlear implantation for children with complex developmental issues seem to be highly related to their developmental profile. Developmental status is an important consideration in counselling families as part of the cochlear implant decision process.

Design: Hearing threshold sound pressure levels were measured up to 20 kHz for the Sennheiser HDA 200 audiometric earphone, and were compared to the ISO 389-5 (2006) norm and other investigations using that earphone and different ones. Study sample: A total of 223 otologically-normal subjects (aged 5-25 years old) participated in the hearing determination. Results: The results are in good agreement with previous studies of hearing thresholds using the same and other earphones. Conclusions: The results of the present investigation are relevant for the international standard for the calibration of audiometric equipment in the 8 to 16 kHz frequency range, ISO 389-5. The data may be used for a future update of the RETSPL for circumaural and insert audiometric earphones. C1 [Rodriguez Valiente, A.; Garcia Berrocal, J.

Design: Retrospective investigation of three two-channel BC ASSR datasets. Subjects: Forty-eight adults (mean age 26.7 years), 49 infants (mean age 29.6 weeks). Methods: BC ASSR stimuli were presented as amplitude/frequency modulated sinusoidal tones with carrier frequencies of 500, 1000, 2000, and 4000 Hz (-10 to 45 dB HL). Results: Infants showed greater differences in ipsilateral/contralateral mean amplitudes and phase delays for all experimental conditions compared to adults. Ninety percent of infants had ipsilateral/contralateral asymmetries at 500 and 4000 Hz (20-35 dB HL) using an "amplitude or phase delay" criterion, and at 4000 Hz (20-25 dB HL) using an "amplitude and phase delay" criterion. Conclusions: As ipsilateral/contralateral asymmetries are not consistently present for 1000- and 2000-Hz BC ASSRs in infants, clinical masking would be needed at these frequencies to isolate the test ear. For 500- and 4000-Hz BC ASSRs, the accuracy of using these asymmetries requires clinical confirmation in a group of infants with hearing loss.

Design: Changes in the pass criteria were: reduction in the signal-to-noise ratio (SNR); reduction in the minimum signal level (MSL); inclusion of the 1-kHz half-octave band; reduction from two to a single half-octave band. Study sample: Data from three screening sites was used within the English newborn hearing screening program from the period 2002 to 2006, with a total number of births of about 40 000. There were 42 bilateral and 43 unilateral cases of significant hearing impairment. Results: No effect on the number of cases detected by follow up diagnostics was observed when: (1) SNR was reduced to a minimum of 5 dB; (2) MSL was reduced to -10 dB SPL; and (3) the 1-kHz band was included. With all these changes the percentage pass rate improved by 0.36%. Conclusions: The current choice of SNR and MSL criteria appears robust. Only a small increase in pass rate is possible without affecting case detection.

Design: Prospective data collection involved participants conducting the system's horizontal calibration test. Eye measurements were then recorded for a 60 degrees deviation (looking from 30 degrees right to -30 degrees left) and repeated after the goggles and infrared camera were removed/repositioned. Participants' eye measurements were also recorded after the geometric calibration had been activated. Study sample: Twenty-two participants with no history of visual or vestibular pathology were recruited for this study. Results: No significant differences were found when the goggles were removed and replaced (p = 0.21); when the infrared camera was repositioned within the goggles (p = 0.50); or when the goggles were removed and the camera repositioned (p = 0.18) after horizontal calibration. A significant difference was found during the assessment of geometric calibration (p <= 0.01). Conclusions: Calibration is not affected by removal or repositioning of the goggles and/or infrared camera within the goggles, therefore suggesting recalibration may not be necessary. Caution should be exercised when using the equipment's geometric calibration and should only be used when the patient is unable to conduct the system's horizontal calibration test.

TI Sudden hearing loss followed by deep vein thrombosis and pulmonary embolism in a patient with factor V Leiden mutation SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Sudden sensorineural hearing loss; factor V Leiden; deep vein thrombosis; pulmonary embolism ID ACTIVATED PROTEIN-C; THROMBOPHILIC RISK-FACTORS; VENOUS THROMBOSIS; RESISTANCE AB Objective: Factor V Leiden (FVL) is by far the most prevalent inherited thrombophilic abnormality in Western countries, and this genetic condition has been associated with sudden sensorineural hearing loss (SSHL). Audiologists should be aware that SSHL may be the precursor of life-threatening thromboembolic events, especially in Caucasians who are more likely to be FVL carriers. Design: Case report. Study sample: A 41-year-old male patient. Results: Although this is not the first report of SSHL in a FVL carrier, it is the first to describe SSHL occurring in a heterozygous FVL carrier who - within a month - was also diagnosed with deep vein thrombosis of the left common femoral, saphenous, and popliteal veins, and pulmonary embolism of the left pulmonary artery branch serving the posterior basal segment of the inferior lobe. Conclusions: SSHL is an emergency condition that warrants prompt medical examination and treatment. Hematological investigations should be considered in SSHL patients at least for those with a family history of thrombotic events, and for women on estrogen-progestin therapy or during pregnancy, with a view to providing adequate antithrombotic prophylaxis and reducing the risk of other thromboembolic events.

Design: Waveforms with and without the application of a notch filter were recorded from babies undergoing routine ABR tests at 4000, 1000 and 500 Hz. Any change in response morphology was judged subjectively. Response latency, amplitude, and measurements of response quality and residual noise were noted. An ABR simulator was also used to assess the effect of notch filtering in conditions of low and high mains interference. Results: The use of a notch filter changed waveform morphology for 500 Hz stimuli only in 15% of tests in newborns. Residual noise was lower when 4000 Hz stimuli were used. Response latency, amplitude, and quality were unaffected regardless of stimulus frequency. Tests with the ABR stimulator suggest that these findings can be extended to conditions of high level mains interference.

Design: The resource contains 700 sentences inspired by the original English Harvard sentences along with speech recordings from a male and female native peninsular Spanish talker. Sentences each contain five keywords for scoring and are grouped into 70 lists of 10 sentences using an automatic phoneme-balancing procedure. Study sample: Twenty-three native Spanish listeners identified keywords in the Sharvard sentences in speech-shaped noise. Results: Psychometric functions for the Sharvard sentences indicate mean speech reception thresholds of -6.07 and -6.24 dB, and slopes of 10.53 and 11.03 percentage points per dB at the 50% keywords correct point for male and female talkers respectively. Conclusions: The resulting open source collection of Spanish sentence material for speech perception testing is available online.

Design: Internet-based cross-sectional survey using open-ended questions. Responses were analysed using a simplified content analysis approach to link concept to ICF categories according to linking rules. Study sample: Hearing health professionals (experts) recruited through e-mail distribution lists of professional organizations and personal networks of ICF core set for hearing loss steering committee members. Stratified sampling according to profession and world region enhanced the international and professional representation. Results: Sixty-three experts constituted the stratified sample used in the analysis. A total of 1726 meaningful concepts were identified in this study, resulting in 209 distinctive ICF categories, with 106 mentioned by 5% or more of respondents. Most categories in the activities & participation component related to communication, while the most frequent environmental factors related to the physical environment such as hearing aids or noise. Mental functions, such as confidence or emotional functions were also frequently highlighted. Conclusions: More than half (53.3%) of the entire ICF classification categories were included in the expert survey results. This emphasizes the importance of a multidimensional tool, such as the ICF, for assessing persons with hearing loss.

Design: Two commercially available tests of auditory gap detection (Random gap detection (RGDT) test, and Gaps-in-noise (GIN) test) were administered to all participants. Study sample: Adult professional musicians (APM) (N = 11, age range 28-61 years); children with central auditory processing disorder (CAPD) (N = 22, age range 7.5-17 years); and first episode psychosis patients (FEP) (N = 17, age range 18-48 years). Results: It was not possible to calculate a threshold for the RGDT for 13 of 22 children with CAPD and for 7 of 17 adults with FEP due to response inconsistency. Analysis of variance (ANOVA) excluding cases that produced inconsistent RGDT results showed that only RGDT thresholds differed across groups (F = 8.73, p = 0.001). Three t-tests comparing test means within group revealed statistically significant differences between the gap detection thresholds obtained with the RGDT vs. the GIN for each group. No significant correlations were seen between RGDT and GIN. Conclusion: Lower/better gap detection thresholds and smaller standard deviations were obtained using the GIN in all three groups. Lack of correlation between the two tests suggests that they may measure different processes.

All participants completed a pretraining examination of their ability to analyse ABR waveforms, eight hours of ABR analysis training over eight weeks using one of three training modes-manual, simulator or combined manual and simulator training, and a posttraining examination of their ability to analyse ABR waveforms. Study sample: Fourteen third-year audiology students (13 female, one male, aged 21 to 22 years) participated in this study. Results: Participants who completed the manual or the combined manual and simulator training achieved significantly higher normalized gain scores on their ABR waveform analysis examinations compared to those who completed the simulator training (p < 0.05). Conclusions: Our findings suggest that the improvements seen in the ability of these audiology students to analyse ABR waveforms were driven primarily by the manual training. The minimal improvements seen in the students who received the simulator training suggest that face-to-face instruction could be required to enhance the ability of audiology students to analyse ABR waveforms.

Design: Sound pressure measurements in the ear canal were used to derive, with hearing threshold measurements, hearing thresholds expressed in terms of the forward-going sound pressure wave, hearing thresholds based on coupler-based calibration, and hearing thresholds expressed in terms of the sound pressure measured at the microphone. Study sample: Fifty-two adults, 18 to 34 years of age, served as the study group. Results: Audiogram configurations were similar up to 2000 Hz for the three expressions of hearing threshold, consistent with the ear canal acting as a simple volume up to this frequency. Above 2000 Hz, notable differences in hearing threshold were found, consistent with the acoustic input impedance of the ear differing from a rigid, hard-walled cavity. Repeat testing showed all three expressions of hearing threshold to be repeatable. High density measurements of hearing threshold from 3000 to 6000 Hz provided qualified support for the derivation of the forward-going sound pressure wave. Conclusions: Hearing thresholds expressed in terms of the forward-going sound pressure wave are repeatable, and with in-situ calibration, may be superior to the current coupler-based method.

Then, we compare our values with existing results at extended high-frequencies (8 to 20 kHz) in an attempt to establish new standards for potential international adoption. Design: A prospective study in a group of otologically healthy subjects. Study sample: A total of 645 subjects aged between 5 and 90 years were recruited. Pure-tone thresholds were determined for conventional and extended high-frequencies. Results: There was an increase in the hearing thresholds as a function of frequency and age. For the 20 to 69 years old group, thresholds were lower in females than in males, especially at 12.5 and 16 kHz. Our threshold values are comparable to those presented in previous studies that used different instrumentation and populations. Conclusions: When comparing different studies the hearing thresholds were found to be similar. Therefore, it would be possible to establish international standard thresholds.

Design: Subjects participated in word and tone identification tasks. Two processing conditions - the conventional advanced combination encoder (ACE) and tone-enhanced ACE were tested. Test materials were Cantonese disyllabic words recorded from one male and one female speaker. Speech-shaped noise was added to clean speech. The fundamental frequency information for periodicity enhancement was extracted from the clean speech. Electrical stimuli generated from the noisy speech with and without periodicity enhancement were presented via direct stimulation using a Laura 34 research processor. Subjects were asked to identify the presented word. Study sample: Seven post-lingually deafened native Cantonese-speaking CI users. Results: Percent correct word, segmental structure, and tone identification scores were calculated. While word and segmental structure identification accuracy remained similar between the two processing conditions, tone identification in noise was better with tone-enhanced ACE than with conventional ACE. Significant improvement on tone perception was found only for the female voice. Conclusions: Temporal periodicity cues are important to tone perception in noise. Pitch and tone perception by CI users could be improved when listeners received enhanced temporal periodicity cues.

Design: Sequencing of the coding region, basal promoter, exon 1, and donor splice site of the GJB2 gene; screening for the presence of the two common GJB6 deletions. Study sample: A cohort of 102 Sicilian NSHL patients. Results: Fifteen different mutations in GJB2 and seventeen different genotypes were detected. No GJB6 mutations were found. The hearing impairment was profound in the 64.72% of probands (mean PTA(0.25-4) kHz of 88.82 +/- 26.52 dB HL). A total of 81.37% of patients harboured at least one c. 35delG allele; c.167delT and c.-23 + 1G > A were identifi ed in 10.78% and the 9.8% of patients respectively; c. 35delG homozygotes presented more severe hearing impairment (75.59% of profound hearing loss) and a higher mean PTA(0.25-4) kHz (96.79 +/- 21.11 dB HL) with respect to c. 35delG/non-c. 35delG and c. 35delG/Wt patients (P < 0.05). Conclusions: This work underlines the role of c.35delG, c.167delT and c.-23 + 1G > A as the most frequent causes of NSHL in Sicily. The c. 35delG frequency found is similar to those reported in other populations of the Mediterranean area. The analysis of genetic and audiologic data confi rmed a variability in the phenotype associated to a single genotype.

Additionally, it clinically evaluates a range of Nucleus 6 and Nucleus 5 programs to determine the performance benefits provided by new input processing technologies available in SmartSound iQ. Design: Speech understanding tests were used to clinically validate the default Nucleus 6 program, by comparing performance outcomes against up to five custom Nucleus 5 or Nucleus 6 programs in a range of listening environments. Clinical comparisons between programs were conducted across the following listening environments; quiet, speech weighted noise (co-located and spatially separated noise), and 4-talker babble (co-located and spatially separated noise). Study sample: Twenty-one adult cochlear implant recipients participated. Results: Significant speech understanding benefits were found with the default Nucleus 6 program compared to the participants 'preferred program using their Nucleus 5 processor and compared to a range of custom Nucleus 6 programs. All participants successfully accepted and upgraded to the new default Nucleus 6 SmartSound iQ program. Conclusion: This study demonstrates the acceptance and clinical benefits of the Nucleus 6 cochlear implant system and SmartSound iQ.

The objective of this study was to ascertain the presence of mutations in WFS1 among children with HI from unknown causes. Design: We screened 105 Finnish children with HI for mutations in exon 8 in WFS1. Study sample: Children were born in a defined area in Northern Finland and they had sensorineural, mild to profound, syndromic, or nonsyndromic HI. They were negative for GJB2 mutations and for the m. 1555A>G and m. 3243A>G mutations in mitochondrial DNA. Results: We found three rare variants and the novel p.Gly831Ser variant in WFS1. Segregation analysis suggested that the novel variant had arisen de novo. The p.Gly831Ser variant may be a new member to the group of heterozygous WFS1 mutations that lead to HI, while the pathogenicity of the rare variant p.Gly674Arg remained unclear. The other two rare variants, p.Glu385Lys and p.Glu776Val, did not segregate with HI in the families. Conclusions: WFS1 gene mutations are a rare cause of HI among Finnish children with HI.

By further developing the online program, it might be possible to foster behavioral changes that will positively affect hearing-aid users. Design: A randomized controlled study with two groups of participants. The intervention group underwent a five-week online intervention while the control group was referred to a waiting list. Questionnaires were used as outcome measures. Study sample: Seventy-six experienced hearing-aid users participated in the study, ranging in age from 26 to 81 years (mean 69.3 years). Results: The findings showed significant improvements in the intervention group after the intervention, measured by the hearing handicap inventory for the elderly. The effects were maintained and improved at the follow-up. Furthermore, the results indicated that the participants in the intervention group improved at two items of the international outcome inventory for hearing aids, and the effects were partly maintained at the follow-up. Finally, significant improvements in the domain of psychosocial wellbeing were found at the follow-up. Conclusions: This study provides further evidence that the internet can be used to deliver intervention of rehabilitation to hearing-aid users.

Design: A listening habit survey was conducted. Subjects were divided into two groups for analysis. A subject was placed within the high risk group if he/she reported listening to music at near maximum volume and had a physical measurement of his/her preferred listening level recorded at >85 dBA. DPOAE and TEOAE levels were measured and compared between the two groups. Study sample: A total of 1928 students from a tertiary educational institution in Singapore. Results: TEOAE levels were found to be significantly lower in the high risk group at 4 kHz. DPOAE levels were also found to be significantly depressed in the high risk group at 1, 2, 3, and 4 kHz with the largest mean difference at 4 kHz. A four-way ANOVA carried out for OAE amplitudes using gender, ear laterality, risk profile, and years of usage as independent factors also showed that risk profile was a significant factor in determining the OAE amplitude at 4 kHz. Conclusion: We have demonstrated that both DPAOE and TEOAE values are diminished in the Asian subjects at high risk for noise exposure.

TI Inflammation is associated with a worsening of presbycusis: Evidence from the MRC national study of hearing SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Presbycusis; age-related hearing loss; inflammation; bio-markers ID OLDER-PEOPLE FINDINGS; ACCELERATED PRESBYCUSIS; HERTFORDSHIRE COHORT; IMMUNE FUNCTIONS; ANIMAL-MODELS; INNER-EAR; PURE-TONE; ADULTS; IMPAIRMENT; MORTALITY AB Objective: Inflammaging, a state of chronic inflammation in the elderly, is now thought to be a key element of the ageing process and contributor to age-related disease. In a previously published study, we identified a significant association between inflammation levels and severity of presbycusis among individuals aged 63 to 73 ("younger old") within an available audiometric range 0.5 to 4 kHz. Our aim was to see if this association would be identified among participants in the MRC national study of hearing, and whether the strength of the association would increase with greater age, or for very low or very high audiometric frequencies. Design: Cross-sectional analysis of cohort data. Study sample: Three hundred and sixty community-dwelling adults age 60 years and over, representing all those with white blood cell count and audiometric data available. Results: A significant independent association between (higher) WBC and (worse) hearing level was identified. This effect increased with age. The strongest association was among those over 75, for whom average hearing threshold levels among those with lower WBC was 17 dB better than those with higher WBC. Conclusions: The current findings support an association between inflammaging (a condition potentially amenable to pharmacological treatment or lifestyle management) and presbycusis.

Design: Retrospective review. Study sample: Seventy-five CAA patients and fifty CAS patients who underwent congenital meatoplasty with canalplasty and tympanoplasty between 2007 and 2012. Results: Paired comparison analyses detected no significant difference in preoperative ABG but significant changes in postoperative ABG, ABG, the number of ABG < 30 dB and ABG < 10 dB between CAA and CAS. Complications such as postoperative stenosis, bony regrowth, external aural canal (EAC) infection, EAC eczema, total deaf, and lateralization of the tympanic membrane (TM) were observed in 61.3% of patients with CAA and 20% of patients with CAS. Chi square test detected significant differences in complications between patients with CAA and CAS (chi(2) = 20.73, p < 0.01). Conclusion: Meatoplasty with canalplasty and tympanoplasty in individuals with CAS can yield reliable and lasting positive hearing results with a low incidence of severe complications. The existence and preoperative condition of patients 'TM and EAC skin helped improve hearing results and decrease the incidence of complications. However, the final hearing results and complications required stricter indications for CAA patients.

Design: The patients answered questions concerning tinnitus laterality, duration, character, aggravation, alleviation, previous treatment, and circumstances of onset. The results of tympanometry, pure-tone audiometry, distortion-product otoacoustic emissions, tinnitus likeness spectrum, MML, and uncomfortable loudness level were evaluated. Study sample: Patients with several tinnitus etiological factors were excluded. The remaining participants were divided into groups according to medical history: acute acoustic trauma: 67 ears; chronic acoustic trauma: 82; prolonged use of oral estrogen and progesterone contraceptives: 46; Meniere's disease: 25; congenital hearing loss: 19; sensorineural sudden deafness: 40; dull head trauma: 19; viral labyrinthitis: 53; stroke: 6; presbycusis: 152. Data of 509 ears were analysed. Results: Tinnitus pitch was highest in patients with acute acoustic trauma and lowest in patients receiving estrogen and progesterone. MML was lowest after acute acoustic trauma and in congenital hearing loss, and highest after a stroke and in the case of presbytinnitus. Conclusions: Tinnitus pitch and MML are etiology dependent.

Close examination of methods across studies exposed the use of variable stimulus parameters, especially rise/fall time (R/FT) and plateau time (PT) as the possible reason. However the effect of variation in R/FT and PT on cVEMP response parameters has been largely uncharted. Design: The study aimed at evaluating the impact of R/FT and PT on cVEMPs elicited by 500-Hz short tone-bursts (STBs) at 95 dB nHL using R/FT from 1 to 4 ms and PT from 0 to 3 ms. Study sample: 30 healthy individuals with normal audio-vestibular system. Results: Significant prolongation of latencies with increasing R/FT and PT (p < 0.05) was noticed. The amplitude however varied significantly only for some R/FTs and PTs. R/FT of 2 ms, in combination with 1-ms PT, produced large amplitudes with lowest variability in amplitude and latency parameters. Conclusions: R/FT of 2 ms along with PT of 1 ms formed a good amalgamation and could be considered optimum for clinical recording of cVEMPs elicited by 500-Hz STBs, although slight deviances in these parameters might not impact the outcome significantly.

This study is investigating whether stimulation closer to the cochlea also gives improved hearing sensitivity. Furthermore, the study compares shifts in hearing sensitivity (BC thresholds) and ear-canal sound pressure (ECSP). Design: BC hearing thresholds and ECSP have been measured for stimulation at two positions: the existing bone-anchored hearing aid (BAHA) position, and a new bone conduction implant (BCI) position that is located closer to the cochlea. Study sample: The measurements were made on 20 normal-hearing subjects. Results: Depending on frequency, the ipsilateral hearing threshold was 3-14 dB better, and the ipsilateral ECSP was 2-12 dB higher for the BCI than for the BAHA position, with no significant differences between threshold and ECSP shifts at group level for most frequencies, and individually only for some subjects. Conclusions: It was found that both the objective ECSP and the subjective hearing threshold measurements gave similar improvement as previous LDV measurements for stimulation closer to the cochlea. One exception was that the LDV measurements did not show the improved sensitivity for frequencies below 500 Hz found here.

Design: Cross-sectional study. Study sample: One hundred and sixty-one workers were studied, 77 exposed to solvents and 84 unexposed. Fourteen solvents were measured, including toluene, xylene, and n-hexane. Pure-tone audiometry and brainstem auditory-evoked potentials (BAEP) were performed. Industrial noise was <85 dBA and exposure levels to organic solvents were low. Results: The exposed group showed a hearing impairment in both ears compared with the unexposed workers. Multiple linear regression models adjusted by age, chronic pathologies, and environmental noise for frequency means between 125 and 8000 Hz produced the following results: for the left ear, R-2 = 33.3%, exposed vs. unexposed beta = 4.1 (p < 0.001); and for the right ear, R-2 = 38%, exposed vs. unexposed beta - 4.8 (p < 0.001). Adjusted for age and chronic pathologies, waves III and V, and interpeak interval latencies were increased (p < 0.05) in both ears in the exposed group. Conclusions: Although solvent mixture concentrations and noise levels were low, our results demonstrate that there may be a concurrent ototoxicity and neurotoxicity condition and emphasize the importance of including BAEP analysis for comprehensive assessments. Future studies that include otoacoustic emissions assessments to monitor cochlear function and central auditory processing tests are imperative.

It follows that any proposed policy or implementation plan that maps highly onto the CCM is more likely to lead to improved outcomes. The aim of this study was to compare long-term condition (LTC) policy documents and audiology quality standard documents with the CCM and to highlight the need for further research in service implementation and clinical outcome. Design: We carried out a keyword-in-context content analysis of relevant documents. Study sample: Documents relating to health department policy on LTCs, audiology service improvement initiatives in England and the CCM. Results: This analysis shows that current audiology implementation documents in England map poorly onto the CCM compared to health policy documents relating to the management of LTCs. The biggest discrepancies occur in self-management support, delivery system design, and decision support. These elements are supported by the best evidence of potential improvements in clinical outcome. Conclusions: Our content analysis of audiology service quality improvement documents in England suggests they compare poorly to some elements of the CCM. We discuss the implications this might have for future research. C1 [Barker, Fiona; de Lusignan, Simon] Univ Surrey, Dept Healthcare Management & Policy, Guildford GU2 7XH, Surrey, England.

User-operated audiometry was developed as an alternative to traditional audiometry for research purposes among musicians. Design: Test-retest reliability of the user-operated audiometry system was evaluated and the user-operated audiometry system was compared with traditional audiometry. Study sample: Test-retest reliability of user-operated 2AFC audiometry was tested with 38 nave listeners. User-operated 2AFC audiometry was compared to traditional audiometry in 41 subjects. Results : The repeatability of user-operated 2AFC audiometry was comparable to traditional audiometry with standard deviation of differences from 3.9 dB to 5.2 dB in the frequency range of 250-8000 Hz. User-operated 2AFC audiometry gave thresholds 1-2 dB lower at most frequencies compared to traditional audiometry. Conclusions: User-operated 2AFC audiometry does not require specific operating skills and the repeatability is acceptable and similar to traditional audiometry. User operated 2AFC audiometry is a reliable alternative to traditional audiometry. C1 [Schmidt, Jesper Hvass; Andersen, Ture] Univ Southern Denmark, Odense Univ Hosp, Dept Audiol, Odense, Denmark.

Design: The National Longitudinal Study on Hearing (NL-SH study) is a large prospective study among adults aged 18 to 70 years, conducted via the internet in the Netherlands. Hearing ability was measured with a digits-in-noise test and comorbidity was assessed through self-report. Study sample: Cross-sectional data of 890 hearing-impaired and 975 normally-hearing adults were analyzed. Both descriptive statistics and multinomial logistic regression analyses were conducted. Results: Of the NL-SH participants with insufficient or poor hearing ability, 78.5% reported to suffer from at least one additional chronic condition. This proportion was larger than in the normally-hearing group (68.6% with one or more chronic conditions and 37.7% with two or more). After adjustment for age and gender, 'dizziness causing falling', 'diabetes' and 'arthritis types other than osteoarthritis and rheumatic arthritis' were significantly associated with poor hearing ability. Conclusions: Our results show that some previously reported associations do not only occur in older age groups, but also in younger cohorts. Comorbidity is relevant in the rehabilitation (multi-disciplinary care) and the clinical encounter.

Design: Pure-tone audiometry, transient evoked otoacoustic emissions (TEOAEs), and distortion product otoacoustic emissions (DPOAEs) were performed in a group of adolescents with and without DM1. Clinical characteristics, disease duration, and glycated haemoglobin levels were studied. Study sample: Participants were 40 adolescents with DM1 and 40 healthy subjects. Results: Sensorineural hearing loss, affecting frequencies of 6000 and 8000 Hz, was found only in DM1 subjects when compared to the controls (7.7% vs. 0%, p < 0.05). A higher prevalence of cochlear damage was detected by DPOAE responses, 32% belonging from the diabetic group, vs. 3.7% in the control group. Absent TEOAE responses were observed in only three individuals, all from the diabetic group (5.1% of the tests performed in the diabetic group). Additionally, hearing thresholds were better in diabetic subjects with good control when compared to ones with regular or poor control (p = 0.00). Hearing thresholds were higher in poorly controlled diabetics when compared to subjects with good (p = 0.000) or regular control (p = 0.006). Conclusion: Early evidence of cochlear damage was detected in adolescents with DM1 leading to hearing loss at high frequencies. Abnormal DPOAEs responses were found more frequently than the alterations in TEOAEs and pure-tone audiometry, suggesting that DPOAEs evaluation is the most sensitive and it could be used for monitoring the progression of cochlear damage during the early stages of hearing impairment.

ISO 16832 describes an internationally standardized CLS procedure for the acoustical domain. This study focuses on the reproducibility of CLS following the recommendations of ISO 16832 using electrical stimuli presented to cochlear implant (CI) users. Design: Repeated CLS measurements were done using single-electrode stimuli at four electrode positions. Loudness growth functions (LGFs) described loudness as a function of level (mu A). LGF shapes were characterized with an exponential b parameter. The reproducibility of the b parameter and inter-session intra-subject differences in percentage dynamic range (DR) between 'Very Soft' and 'Loud - Very Loud' levels were analysed. Study sample: Ten CI users. Results: Inter-session differences did not significantly differ between loudness categories or electrode positions. Across loudness categories the standard deviation of inter-session differences equalled 7.2% DR. The reproducibility of LGF shapes was moderate (r = 0.63). The LGFs of 43% of the measured electrodes significantly deviated from linear (nonzero b parameter). Conclusions: The reproducibility was comparable to the reproducibility for acoustical stimulation in normal-hearing and hearing-impaired listeners. CLS data for electrical stimuli are preferably fitted with a model that is flexible in describing LGF shapes.

Design: Two experiments were conducted, one with auditory-only (AO) and one with auditory-visual (AV) stimuli, both using the same speech recognition in noise materials. Four signal-to-noise ratios (SNRs) were used, two in each experiment. The two SNRs targeted 80% and 50% correct performance. Motivation was manipulated by either having participants listen carefully to the speech (low motivation), or listen carefully to the speech and then answer quiz questions about the speech (high motivation). Study sample: Sixteen participants with normal hearing participated in each experiment. Eight randomly selected participants participated in both. Results: Using AO and AV stimuli, motivation generally increased subjective ratings of listening effort and tiredness. In addition, using auditory-visual stimuli, motivation generally increased listeners' willingness to do something to improve the situation, and decreased their willingness to avoid the situation. Conclusions: These results suggest a listener's mental state may influence listening effort and choice of coping strategy.

TI Severe auditory processing disorder secondary to viral meningoencephalitis SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory processing disorder; meningoencephalitis ID CORTICAL DEAFNESS; PERCEPTION; AGNOSIA; CHILD AB Objective: To describe auditory function in an individual with bilateral damage to the temporal and parietal cortex. Design: Case report. Study sample: A previously healthy 17-year old male is described who sustained extensive cortical injury following an episode of viral meningoencephalitis. He developed status epilepticus and required intubation and multiple anticonvulsants. Results: Serial brain MRIs showed bilateral temporoparietal signal changes reflecting extensive damage to language areas and the first transverse gyrus of Heschl on both sides. The patient was referred for assessment of auditory processing but was so severely impaired in speech processing that he was unable to complete any formal tests of his speech processing abilities. Audiological assessment utilizing objective measures of auditory function established the presence of normal peripheral auditory function and illustrates the importance of the use of objective measures of auditory function in patients with injuries to the auditory cortex. Conclusions: Use of objective measures of auditory function is essential in establishing the presence of normal peripheral auditory function in individuals with cortical damage who may not be able to cooperate sufficiently for assessment utilizing behavioral measures of auditory function.

TI Hearing threshold levels for a population of 11 to 35 year old Australian females and males SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing thresholds; adolescents; hearing loss AB Objective: Detailed information on the hearing threshold levels (HTLs) of young Australians was gathered as part of a large-scale study of the relationship between HTL and leisure-noise exposure in young Australians. Design: HTL data for the study population (18-35 year olds) was carefully collected, as well as otoscopy, tympanometry, contra-lateral acoustic reflexes, and otoacoustic emissions (transient and distortion product), together with a comprehensive hearing health history - both past and present. Study sample: The sample cohort consisted of 1407 individuals, females and males. Results: Prior to analysis, HTL data were filtered according to both a 'Low' and 'High' set of exclusion criteria. The results obtained for both high-screen and low-screen datasets were around +5 dB above the traditionally accepted values of audiometric zero. This is consistent with previous published reports. Conclusion: Comparison with 'ISO 7029 Acoustics: Statistical distribution of hearing thresholds as a function of age 'indicated that threshold values for this dataset have a similar distribution to those of the Standard. This data provides a suitable reference HTL ('normative') database for young Australians. C1 [Williams, W.; Carter, L.; Seeto, M.] Natl Acoust Labs, Sydney, NSW, Australia.

Simple musical structures, lyrics that are easy to follow, and clear rhythm/beat have been reported among the top factors to enhance music enjoyment. The present study investigated the preference for modified relative instrument levels in music with normal-hearing and cochlear implant subjects. Design: In experiment 1, test subjects were given a mixing console and multi-track recordings to determine their most enjoyable audio mix. In experiment 2, a preference rating experiment based on the preferred relative level settings in experiment 1 was performed. Study sample: Experiment 1 was performed with four postlingually deafened cochlear implant subjects, experiment 2 with ten normal-hearing and ten cochlear implant subjects. Results: A significant difference in preference rating was found between normal-hearing and cochlear implant subjects. The latter preferred an audio mix with larger vocals-to-instruments ratio. In addition, given an audio mix with clear vocals and attenuated instruments, cochlear implant subjects preferred the bass/drum track to be louder than the other instrument tracks. Conclusions: The original audio mix in real-world music might not be suitable for cochlear implant recipients. Modifying the relative instrument level settings potentially improves music enjoyment.

The objective of this study was to examine data collected with a revised Danish translation of the IOI-HA in order to: (1) evaluate the effect of the revision, and (2) to examine if the psychometric properties of the revised translation of the IOI-HA are equivalent to those of previously validated translations. Design: Psychometric properties were evaluated performing inter-item correlation analysis, principal component analysis, and item-total correlation. Study sample: Three hundred forty-one adult hearing-impaired participants - all of whom were voluntary hearing aid testers attached to the Global Audiology Group in GN ReSound A/S on a non-payment basis - were mailed a revised Danish IOI-HA questionnaire. Results: Statistical analysis revealed good internal consistency along with a clear division of items into two distinct factors. Conclusions: The revised Danish translation of the IOI-HA proves internally consistent. Furthermore, it possesses psychometric properties equivalent to those reported in several corresponding studies of other translations. Data obtained from it can therefore validly be considered comparable to data obtained from previously validated translations of the IOI-HA.

TI The characteristics of Audioscan and DPOAE measures in tinnitus patients with normal hearing thresholds SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audioscan; DPOAE; notches; tinnitus; normal hearing thresholds ID PRODUCT OTOACOUSTIC EMISSION; AUDIOGRAM; PITCH AB Objectives: To investigate auditory dysfunction in patients with tinnitus and normal hearing thresholds using two sensitive audiological measures. Design: The study was designed to investigate the characteristics of Audioscan and DPOAE tests in tinnitus patients with normal hearing thresholds. Audioscan and DPOAE notches were analysed and compared. All tests were performed in a sound-treated chamber or in a sound-treated room. Study sample: Forty-five tinnitus patients with normal hearing thresholds were examined following a written clinical protocol. Results: The averaged hearing levels obtained from tinnitus participants were significantly worse at high frequencies than those derived from the normative data. There was a significantly higher prevalence of Audioscan and DPOAE notches, whose central frequencies matched tinnitus frequencies in the mid-frequency regions, but not in the low-and high-frequency regions. A significant correlation was found between the centre frequencies of the Audioscan notches and the DPOAE notches from 500 to 4000 Hz. Conclusion: Tinnitus in different frequency regions may be associated with different underlying mechanisms of tinnitus generation. Some negative results on the Audioscan and DPOAE notches matching tinnitus pitches may be due to a limited set of discrete frequencies used for the tinnitus pitch matching test.

Design: Listener-specific error rate and familiarity rating of 200 NU-6 words were obtained. Lexical data (normative familiarity, frequency of occurrence, neighborhood density, and frequency of neighborhood competitors) for these words were obtained from the Hoosier mental lexicon. Study sample: Participants included 10 monolinguals and three groups of 10 bilinguals differing mainly in age of acquisition and length of schooling/working in English. Results: Lexical effects were minimal for monolinguals' word recognition. Listener-specific familiarity rating correlated to error rate better than the Hoosier normative rating. Frequency of occurrence was the most significant lexical variable in accounting for bilinguals' measures and its effect was the greatest on bilinguals foreign born and educated. Age of English acquisition tended to affect familiarity rating, whereas length of schooling/working in English tended to affect error rate. Conclusions: Frequency of word occurrence significantly affects bilinguals' familiarity rating and error rate of the NU-6 words. Listener-specific familiarity rating should be obtained to best predict error rate on the test. C1 Long Isl Univ, Dept Commun Sci & Disorders, Brooklyn, NY 11201 USA.

Design: Participants were assessed for SPD with the Listening in Spatialized Noise - Sentences test (LiSN-S). Participants diagnosed with SPD were instructed to use the LiSN & Learn auditory training software until 100 games had been completed. Study sample: Participants were 144 Indigenous Australian children (aged between 6; 0 [years; months] and 12; 2). Results: Ten participants (6.9%) presented with SPD. Nine took part in the auditory training study. Post-training LiSN-S performance improved on average by 0.9 population standard deviations (1.4 dB). There was a significant correlation (r = 0.71, p = 0.031, eta(2) = 0.51) between total number of LiSN & Learn games played (mean = 65, SD = 27) and improvement in LiSN-S performance. Teachers rated all participants as improving in their listening abilities post-intervention. Conclusions: There is a high prevalence of SPD in the Indigenous Australian population. LiSN & Learn training is effective in remediating SPD in this population and is considered a beneficial intervention by teachers, however improvement in spatial processing is dependent on training program uptake.

Design: The test is based on the Danish speech material Dantale II, which consists of five words sentences (Wagener et al, 2003). For each word presented the subject selected a response from ten alternative words. Two versions of the test were made: one with and one without the possibility that for each word presented the subject could answer "I do not know" (?-button). Using a listening test the two versions were evaluated against a traditional test, where the subjects orally repeated the words that were perceived. Study sample: Twenty-four normal-hearing subjects. Results: The speech intelligibility as a function of the signal-to-noise ratio can be described by logistic functions in the different user-operated tests and in the traditional test. The logistic parameters obtained from the user-operated test with the ?-button agree with the parameters obtained in a traditional test. The homogeneity of the speech material is uninfluenced when the material is used in a user-operated test. Conclusions: It is reasonable to use the Dantale II speech material for a user-operated speech in noise test, and the use of the ?-button is favourable.

TI Proposed norms for the Glasgow hearing-aid benefit profile (GHABP) questionnaire SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing impairment; disability; handicap ID QUALITIES; SPEECH AB Objective: To form a normative set of responses to the GHABP questionnaire from a large regional dataset. Design : Participants were asked to rate their hearing disability, handicap, hearing-aid (HA) use, HA benefit, HA satisfaction, and residual (aided) disability on a five-point scale for four situations: quiet conversation, television (TV) listening, noisy conversation, and group conversation. A subset of participants also estimated the time spent in these situations. Study sample : A group of 1574 adults with normal to profound hearing thresholds participated. Results: There was a significant relationship between increasing perceived disability and increasing hearing loss as given by the better-ear audiometric average (BEA). Responses for HA measures did not vary greatly with hearing loss: HA use was reported as high, whereas residual disability, HA benefit, and satisfaction were all reported on average as moderate. Conclusions: The results can be used as a normative dataset with which to evaluate individual responses in the clinic, where the GHABP provides a useful short-form questionnaire to engage the patient. The lack of systematic changes in hearing-aid related responses shows room for improvement in the benefit afforded by amplification.

Design: The KAB was completed by 235 participants. Relationships between knowledge and attitudes about hearing and hearing conservation, participation in noisy activities, and use of hearing protection were examined. Study sample: 117 males and 118 females aged between 18 and 80 years (mean = 42.3, SD = 4.1) recruited from the Portland VA Medical Center, local universities, and a community college. Results: Knowledge scores ranged from 15.6% to 93.8%. Factor analyses revealed six attitude factors, interpreted as measuring perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, and cues to action. Over 95% of participants routinely participated in at least one noisy activity but few used hearing protection while doing so. The attitude scores of individuals who used hearing protection differed significantly from the scores of those who did not. Conclusions: Significant relationships between use of hearing protection and scores on the KAB provide validation that the HBM is a valuable framework for understanding hearing health behaviors, and evidence that the KAB is a valid tool for assessing these attitudes and behaviors.

TI Benefit from non-linear frequency compression hearing aids in a clinical setting: The effects of duration of experience and severity of high-frequency hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aids; frequency compression; acclimatization ID IMPAIRED LISTENERS; SPEECH; AUDIBILITY; CHILDREN; INTELLIGIBILITY; OUTCOMES AB Objectives: To determine whether non-linear frequency compression (NLFC) is effective for hearing-impaired adults in a clinical setting. To determine whether benefit from NLFC is related to duration of NLFC experience or severity of high-frequency hearing loss. Design: Participants were fitted with Phonak frequency compression hearing aids as part of their standard clinical care, using the manufacturer's default fitting settings. Participants had been using NLFC for between 1 and 121 weeks at the time of testing. Speech recognition thresholds in noise and consonant recognition in quiet were measured with and without NLFC enabled. Study sample: Forty-six experienced adult hearing-aid users. Results: Consonant recognition in quiet, but not speech recognition in noise was significantly better with NLFC enabled. There was no significant correlation between duration of frequency compression experience and benefit. Benefit for consonant recognition was negatively correlated with mean audiometric thresholds from 2-6 kHz. Conclusions: NLFC was beneficial for consonant recognition but not speech recognition in noise. There was no evidence to support the idea that a long period of acclimatization is necessary to gain full benefit. The relation between benefit and high-frequency thresholds might be explained by the poor audibility of compressed information for some listeners with severe loss.

Design: Retrospective study with the comparative analysis of two groups of children. Study sample: Cases identified from screening were selected from 34 321 preschool children who underwent screening for delayed-onset hearing loss between October 2009 and May 2011. Sporadic cases of delayed-onset hearing loss were selected from pediatric clinical records. Cases from the first group were excluded from the latter to avoid duplication. Two groups were given the same questionnaire to record risk indicators, diagnosis, and age at intervention. Results: The average age of 26 children at the time of diagnosis in the screening group (52.81 +/- 13.23 months) was significantly earlier than in the 33 cases identified in the sporadic group (62.03 +/- 12.86 months; p < 0.05). The age at intervention of children with bilateral moderate to severe hearing loss in the screening group (50.40 +/- 10.76 months) was also earlier than in the sporadic group (62.73 +/- 13.77 months; p < 0.05). Conclusions: Improved rates of early diagnosis could therefore be achieved with hearing screening for preschool children with no significant symptoms of delayed-onset hearing loss.

Design: Participants heard a series of three words (S1, S2, and S3). The task was to indicate whether S2 was in the same semantic category as S3. Semantic priming was quantified as the difference between AERPs to the second word when it was semantically related to the first word (S2-R) or unrelated to the first word (S2-UR). Interest was focused entirely on the processing negativity (PN) component of the AERP to S2. The purpose of S3 was to delay the task decision so that the LPC generated by the decision would not confound the measurement of the PN component to S2. Sample: Ten children (9-11 years), 11 young adults (20-30 years), and 10 seniors (60-70 years). Results: The semantic priming effect was evident in the difference between peak amplitude of the PN component of the AERP to S2R and S2UR in all three groups. Children showed a clear asymmetry favoring the left hemisphere. In young adults, the asymmetry still favored the left hemisphere, but the degree of asymmetry was less robust. In the case of seniors, the priming effect was greater over the right hemisphere. Conclusion: Results suggest that all age groups benefit from contextual support, as evidenced by the semantic priming effect. However, differences in hemispheric asymmetry of activation indicate that perhaps seniors may need to recruit additional, but somewhat different brain resources to manage otherwise largely automatic tasks.

Therefore, this parametric study was designed to compare the effect of binaural and monaural stimuli presentation on speech-evoked ABR features in the parallel assessment of subcortical asymmetry of speech stimuli acoustic elements. Design: Electrophysiological responses to the speech syllable /da/ were recorded within three stimulus presentation modes. Study sample: Forty-eight normal hearing monolingual Persian speakers were included in the current study as volunteer cases. Results: Shorter right ear latency was observed for peaks A and E, but the overall response timing was comparable within different stimulus presentation modes. Binaural stimulation generally led to larger response than monaural stimulation and affected the encoding of speech spectral elements. Moreover, no significant interpeak interval difference was observed in the sustained portion of responses. Response to the right and left ear stimulation was highly correlated, and a symmetrical pattern was observed between the two ears. Conclusions: The timing of speech-evoked responses is not related to the stimulus presentation mode; however, binaural stimulation produces more robust responses. Lateral asymmetry in the representation of speech elements was not considerable at the brainstem level.

TI Influence of dose and duration of isoflurane anesthesia on the auditory brainstem response in the rat SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Electrophysiology; isoflurane; auditory brainstem response; latency; rat ID EVOKED-POTENTIALS; OTOACOUSTIC EMISSIONS; GENERAL-ANESTHESIA; STAPEDIUS REFLEX; PROPOFOL; VOLATILE; HUMANS; MEMORY AB Objective: Isoflurane anesthesia can have significant effects on processing of sounds at the peripheral and central levels, manifesting in changes in auditory-evoked potentials. The current study tested whether duration of isoflurane anesthesia changes thresholds, amplitudes, and latencies of the auditory brainstem response (ABR). Design: The study tested ABRs in a rat animal model under isoflurane anesthesia. Study variables were duration of isoflurane anesthesia, stimulus frequency, stimulus level, and the dose of isoflurane. Rats were anesthetized with 1.5% or 2% isoflurane. ABRs were collected from 90 to 5 dB SPL at 5-40 kHz. Three full ABR series were collected over a 105-minute period. Thresholds were assigned, and ABR wave amplitudes and latencies were measured at each stimulus frequency and level. Study sample: Ten Sprague-Dawley rats were tested in a repeated measures design. Results: Statistical analyses revealed no significant effects of dose or duration on threshold, but a series of significant interactions between test variables for the amplitude and latency measurements. Conclusions: In the rat, dose and duration of isoflurane anesthesia induced inconsistent changes in latency and amplitude of the ABR. At 40 kHz, isoflurane dose had more powerful effects on latency and amplitude than occurred at other frequencies. C1 Ohio State Univ, Dept Speech & Hearing Sci, Columbus, OH 43220 USA.

For a hearing-impaired person, a hearing aid is often beneficial, but noise and annoying sounds can result in non-use of the hearing aid, temporary or permanently. Objective: The purpose of this study was to identify annoying sounds in a daily soundscape for hearing-aid users. Design: A diary was used to collect data where the participants answered four questions per day about annoying sounds in the daily soundscape over a two-week period. Study sample: Sixty adult hearing-aid users. Results: Of the 60 participants 91% experienced annoying sounds daily when using hearing aids. The annoying sound mentioned by most users, was verbal human sounds, followed by other daily sound sources categorized into 17 groups such as TV/radio, vehicles, and machine tools. When the hearing-aid users were grouped in relation to age, hearing loss, gender, hearing-aid experience, and type of signal processing used in their hearing aids, small and only few significant differences were found when comparing their experience of annoying sounds. Conclusions: The results indicate that hearing-aid users often experience annoying sounds and improved clinical fitting routines may reduce the problem.

TI Low-frequency signals support perceptual organization of implant-simulated speech for adults and children SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Electric-acoustic stimulation; perceptual organization; hearing loss; bimodal stimulation; hybrid implants ID ELECTRIC-ACOUSTIC STIMULATION; COCHLEAR-IMPLANT; SPECTRAL INTEGRATION; WORD RECOGNITION; BIMODAL HEARING; OPPOSITE EAR; CUES; PHONEME; CONTEXT; SYSTEM AB Objective: Using signals processed to simulate speech received through cochlear implants and low-frequency extended hearing aids, this study examined the proposal that low-frequency signals facilitate the perceptual organization of broader, spectrally degraded signals. Design: In two experiments, words and sentences were presented in diotic and dichotic configurations as four-channel noise-vocoded signals (VOC-only), and as those signals combined with the acoustic signal below 0.25 kHz (LOW-plus). Dependent measures were percent correct recognition, and the difference between scores for the two processing conditions given as proportions of recognition scores for VOC-only. The influence of linguistic context was also examined. Study sample: Participants had normal hearing. In all, 40 adults, 40 seven-year-olds, and 20 five-year-olds participated. Results: Participants of all ages showed benefits of adding the low-frequency signal. The effect was greater for sentences than words, but no effect of diotic versus dichotic presentation was found. The influence of linguistic context was similar across age groups, and did not contribute to the low-frequency effect. Listeners who had poorer VOC-only scores showed greater low-frequency effects. Conclusion: The benefit of adding a low-frequency signal to a broader, spectrally degraded signal derives in some part from its facilitative influence on perceptual organization of the sensory input.

Design: This is a prospective longitudinal controlled study. Study sample: Third to fifth graders (n = 220) filled out a baseline questionnaire; participated in a 60 minutes Dangerous Decibels (R) classroom presentation; answered a follow-up questionnaire immediately after the presentation; worked with their teachers on an activity booklet about hearing health ten weeks later; and filled out a three-months follow-up questionnaire. Students that did not receive health hearing education served as a control group (n = 51). A mixed analysis of variance was performed, with time as the within-subjects independent variable, and the intervention as the between-subjects independent variable. Results: The study group exhibited significant short- and long-term improvements in knowledge, attitudes, and intended behavior related to NIHL and acoustic trauma prevention, and in decreased exposures to loud sounds and barriers to the use of hearing protective strategies. Conclusions: This study demonstrated the effectiveness of a Brazilian version of the Dangerous Decibels classroom program with an additional supplementary workbook intervention.

TI Warfighter auditory situation awareness: Effects of augmented hearing protection/enhancement devices and TCAPS for military ground combat applications SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory detection; auditory identification; hearing protection; impulse noise; military hearing; noise exposure; situation awareness; fitness for duty ID PROTECTION; AUGMENTATIONS; ENHANCEMENT; DESIGN; NOISE AB Objective: To determine the effects of current hearing protection/enhancement devices (HPEDs) and tactical communications and protection systems (TCAPS) on auditory detection and identification of three critical military signals associated with potential "threats." Design: Utilizing a 6 x 3 within-subject experimental design, 24 normal-hearing Virginia Tech Reserve Officer Training Corps (ROTC) cadets and active duty soldiers participated. Study sample: Five HPEDS and TCAP devices plus the open ear were tested. On each trial, either wearing a device or with open ears, subjects walked along a 3000-foot line of discrete distance markers toward the auditory threat, which was not visible but still within line-of-sight over flat terrain, stopping to listen when instructed. On approach to the threat, the linear distance at first detection was measured, followed by a continued approach until positive identification occurred. Then the subject reversed direction, retreating away from the threat until detection was lost. Results: ANOVA and post hoc tests were applied to determine statistically-significant differences among HPEDs, TCAPS, and the open ear on the objective detection and identification distance measures. Conclusions: The results have serious implications for selection of HPDs, HPEDs, and TCAPS for applications where preservation of auditory situational awareness via the fundamental detection and identification tasks are essential.

TI Short-term variability of pure-tone thresholds obtained with TDH-39P earphones SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiometry; noise-induced hearing loss; reliability; occupational health ID HEARING CONSERVATION PROGRAM; SENNHEISER HDA-200; NOISE; RELIABILITY; PERMANENT; SHIFT AB Objective: To estimate the short-term variability and correlates of variability in pure-tone thresholds obtained using audiometric equipment designed for occupational use, and to examine the justification for excluding 8 kHz as a mandatory threshold in occupational hearing conservation programs. Method: Pure-tone thresholds and other hearing-related tests (e.g. noise dosimetry, otoscopy, middle-ear assessment) were conducted with a group of 527 adults between 20 and 69 years of age. Five measurement visits were completed by participants within 14 days. Results: The 50% critical difference boundaries were -5 and 0 dB at 4 kHz and below and -5 and 5 dB at 6 and 8 kHz. The likelihood of spurious notches due to test-retest variability was substantially lower than the likelihood of failing to detect a notched configuration when present. Correlates of variability included stimulus frequency, baseline threshold, acoustic reflectance of the ear, average noise exposure during the previous eight hours, age, and the tester's level of education in audiology. Conclusion: The short-term variability in 8-kHz pure-tone thresholds obtained with the TDH-39P earphone was slightly greater than at other frequencies, but this difference was not large enough to justify the disadvantages stemming from the inability to detect a 6-kHz notch.

TI Auditory risk estimates for youth target shooting SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Firearms; youth; recreational shooting; noise-induced hearing loss; auditory risk; impulse noise ID HEARING-LOSS; NOISE; CHILDREN AB Objective: To characterize the impulse noise exposure and auditory risk for youth recreational firearm users engaged in outdoor target shooting events. The youth shooting positions are typically standing or sitting at a table, which places the firearm closer to the ground or reflective surface when compared to adult shooters. Design: Acoustic characteristics were examined and the auditory risk estimates were evaluated using contemporary damage-risk criteria for unprotected adult listeners and the 120-dB peak limit suggested by the World Health Organization (1999) for children. Study sample: Impulses were generated by 26 firearm/ammunition configurations representing rifles, shotguns, and pistols used by youth. Measurements were obtained relative to a youth shooter's left ear. Results: All firearms generated peak levels that exceeded the 120 dB peak limit suggested by the WHO for children. In general, shooting from the seated position over a tabletop increases the peak levels, L-Aeq8 and reduces the unprotected maximum permissible exposures (MPEs) for both rifles and pistols. Pistols pose the greatest auditory risk when fired over a tabletop. Conclusion: Youth should utilize smaller caliber weapons, preferably from the standing position, and always wear hearing protection whenever engaging in shooting activities to reduce the risk for auditory damage.

TI Methods for evaluating temporal trends in noise exposure SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Noise; hearing conservation; demographics/epidemiology; psychoacoustics/hearing science ID HEARING CONSERVATION PROGRAM; WORKERS; CONSTRUCTION; MILITARY; IMPACT; SURVEILLANCE; PREVENTION; PROTECTION; HEALTH; INJURY AB Objective: Hearing conservation programs have been mandatory in many US industries since 1983. Since then, three program elements (audiometric testing, hearing protection, and training) have been the focus of much research. By comparison, little has been done on noise exposure evaluation. Design: Temporal trends in time weighted average (TWA) exposures and the fraction of measurements exceeding 85 dBA were evaluated by facility, by exposure group within facility, and by individual worker within facility. Study sample: A large dataset (> 10 000 measurements over 20 years) from eight facilities operated by a multinational aluminum manufacturing company was studied. Results: Overall, exposures declined across locations over the study period. Several facilities demonstrated substantial reductions in exposure, and the results of mean noise levels and exceedance fractions generally showed good agreement. The results of analyses at the individual level diverged with analyses by facility and exposure group within facility, suggesting that individual-level analyses, while challenging, may provide important information not available from coarser levels of analysis. Conclusions: Validated metrics are needed to allow for assessment of temporal trends in noise exposure. Such metrics will improve our ability to characterize, in a standardized manner, efforts to reduce noise-induced hearing loss. C1 [Neitzel, R.

TI Temporary threshold shift after impulse-noise during video game play: Laboratory data SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Gunshot; impulse noise; video game; temporary threshold shift; TTS; hearing ID INDUCED HEARING-LOSS; AUDITORY RISK; OTOACOUSTIC EMISSION; SENNHEISER HDA-200; N-ACETYLCYSTEINE; ACETYL-CYSTEINE; ACOUSTIC INJURY; AGE; EXPOSURE; MUSIC AB Objective: Prevention of temporary threshold shift (TTS) after laboratory-based exposure to pure-tones, broadband noise, and narrowband noise signals has been achieved, but prevention of TTS under these experimental conditions may not accurately reflect protection against hearing loss following impulse noise. This study used a controlled laboratory-based TTS paradigm that incorporated impulsive stimuli into the exposure protocol; development of this model could provide a novel platform for assessing proposed therapeutics. Design: Participants played a video game that delivered gunfire-like sound through headphones as part of a target practice game. Effects were measured using audiometric threshold evaluations and distortion product otoacoustic emissions (DPOAEs). The sound level and number of impulses presented were sequentially increased throughout the study. Study sample: Participants were normal-hearing students at the University of Florida who provided written informed consent prior to participation. Results: TTS was not reliably induced by any of the exposure conditions assessed here. However, there was significant individual variability, and a subset of subjects showed TTS under some exposure conditions. Conclusions: A subset of participants demonstrated reliable threshold shifts under some conditions. Additional experiments are needed to better understand and optimize stimulus parameters that influence TTS after simulated impulse noise. C1 [Spankovich, C.; Griffiths, S.

Design: A descriptive study using a 28-item survey administered by personal interview. Study sample: Two-hundred and ten youth aged 10 to 17 years responded. Results: Seventy-eight percent of those surveyed began shooting before the age of ten. The majority reported using large caliber firearms capable of rapid fire for both hunting and target practice. Most youths in this study were not aware of, and therefore, were not utilizing HPDs specifically designed for the shooting sports. Ten percent of subjects reported constant tinnitus and 45% notice tinnitus occurred or worsened after shooting. Although the majority of YRFUs reported good or perfect hearing, a small percentage (4-5%) of youth reported having only "fair" hearing. Conclusion: YRFUs are putting themselves at risk beginning at a young age for noise-induced hearing loss (NIHL) and tinnitus based on self-reported shooting habits and inconsistent use of HPDs during both target practice and hunting activities. This research highlights the need for early education and intervention efforts to minimize the risk of NIHL in youth.

Study sample: Audiological data of 40 123 South African mine workers were investigated. Data of a non-noise-exposed control group (n = 6162) and group exposed to underground noise (>= 85 dB A (TWA) (n = 33 961) were included. Within these two larger noise-exposed groups two homogenous exposure groups (HEG) were also selected for analyses, namely the driller group (n = 4399) and the administration group (administrative workers) (n 2211). Participants were categorized in terms of noise exposure, age, and race. Results: Significantly different thresholds (worse for underground noise group) with respect to the median for all frequencies after adjusting for age was evident between the noise-exposed and control groups (ANCOVA). The largest differences in hearing thresholds between the noise-exposed and control groups were observed at 3 and 4 kHz in the age group 36 to 45 years. Administration and driller group differed significantly (driller group worse results) with respect to the mean LFA512 and HFA346 after adjusting for age (ANCOVA). Black males had significantly better high-frequency hearing compared with white male counterparts but significantly worse low-frequency hearing. Conclusion: Age was the most important influence on hearing thresholds for the noise and control groups. Race was shown to be a very significant factor determining susceptibility to NIHL and ARHL.

Design : A 2 x 2 x 6 mixed design with correlational analyses was used to compare participant results on a standardized listening in noise sentence repetition task (QuickSin; Killion et al, 2004), presented in an auditory and an audiovisual condition as signal-to-noise ratio (SNR) varied from 25-0 dB and to determine individual differences in working memory capacity and short-term recall. Study sample: Thirty-eight young adults without ADHD and twenty-five young adults with ADHD. Results: Diagnosis, modality, and signal-to-noise ratio all affected the ability to process speech in noise. The interaction between the diagnosis of ADHD, the presence of visual cues, and the level of noise had an effect on a person's ability to process speech in noise. Conclusion: Young adults with ADHD benefited less from visual information during noise than young adults without ADHD, an effect influenced by working memory abilities. C1 [Michalek, Anne M.

Design: Retrospective study. Study sample: Seventy-five patients with unilateral sudden deafness underwent an inner-ear test battery. Registering the grades of sudden deafness was based on the number of abnormal test results in the inner ear test battery. Results: After treatment for three consecutive months, mean hearing gain declined significantly from Grade I (one abnormal test) to Grade IV (four abnormal tests). Significant relations existed between hearing outcome and oVEMP test results (p < 0.05), caloric test results (p < 0.05), but not cVEMP test results and pre-treatment mean hearing level. Combined caloric and oVEMP test results demonstrated a stronger predictor with a c statistic of 0.722 than either test alone, indicating that this regression model fits the whole set of observations well and is effective in predicting the hearing outcome. Conclusion: Abnormal caloric and oVEMP test results in sudden deafness patients may indicate poor prognosis for hearing improvement, whereas hearing recovery can be anticipated when both tests reveal normal responses.

TI Clinical assessment of spectral modulation detection for adult cochlear implant recipients: A non-language based measure of performance outcomes SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Spectral modulation detection; spectral envelope perception; spectral modulation detection; spectral resolution; cochlear implants; speech understanding; word recognition ID SPEECH RECOGNITION; RIPPLE RESOLUTION; NORMAL-HEARING; LISTENERS; PERCEPTION; NOISE; USERS; REVERBERATION; LISTS AB Objective: Spectral modulation detection (SMD) provides a psychoacoustic estimate of spectral resolution. The SMD threshold for an implanted ear is highly correlated with speech understanding and is thus a non-linguistic, psychoacoustic index of speech understanding. This measure, however, is time and equipment intensive and thus not practical for clinical use. Thus the purpose of the current study was to investigate the efficacy of a quick SMD task with the following three study aims: (1) to investigate the correlation between the long psychoacoustic, and quick SMD tasks, (2) to determine the test/retest variability of the quick SMD task, and (3) to evaluate the relationship between the quick SMD task and speech understanding. Design: This study included a within-subjects, repeated-measures design. Study sample: Seventy-six adult cochlear implant recipients participated. Results: The results were as follows: (1) there was a significant correlation between the long psychoacoustic, and quick SMD tasks, (2) the test-retest variability of the quick SMD task was highly significant and, (3) there was a significant positive correlation between the quick SMD task and monosyllabic word recognition. Conclusions: The results of this study represent the direct clinical translation of a research-proven task of SMD into a quick, clinically feasible format.

However, it does have an advantage of being a predominantly reflection emission. The reflection component has been found to be sensitive to cochlear damage. Our objective was to compare the two types of DPOAE to track subtle changes due to aging. Design: We used the most suitable stimulus parameters to record the fine structures of 2f2-f1 DPOAE and 2f1-f2 DPOAE for comparison in two groups of individuals. Study sample: Young adults and middle-aged adults with normal hearing sensitivity participated in the experiment. Both ears of all participants were tested. Results: Although reductions were noted in the both types of DPOAE in the middle-aged participants compared with the young adults, the decrease in amplitude of the 2f2-f1 DPOAE was found to be statistically significant. This corresponded with statistically significant reductions in the reflection component of the 2f1-f2 DPOAE. Reductions in the 2f2-f1 DPOAE were found with both, high-level and low-level primaries. Conclusions: These results highlight the advantages of analysing fine structure data of the 2f2-f1 DPOAE to track subtle cochlear changes in response to aging.

Design: Persons with different degrees of self-reported hearing impairment completed an online questionnaire constructed from items taken from the literature on communication strategies but reworded to be understood by people with normal hearing. Tactics were examined for frequency of use in two severities of impairment and between genders. All the data were then factor analysed and factor scores related to variables of relevance to communication. Study sample: A large convenience sample (n = 188) with a range of self-assessed hearing impairment from normal to profound. Results: Descriptive data revealed some differences in frequency of use in relation to severity and gender. Factor analysis yielded six clearly interpretable factors, the largest relating to disengagement (avoidance). Self-assessed impairment was chiefly associated with a speech reading tactic, negatively with environmental optimization strategies, and to a small extent with disengagement and conversation repair. Conclusions: Only the tactic of speech reading was closely associated with impaired hearing, with some evidence that females were more inclined to use it.

Design: Word and sentence stress perception, discrimination of fundamental frequency (F0), intensity and duration, and forward digit span were measured twice over approximately 16 months. Musical activities were assessed by questionnaire. Study sample: Twenty-one early-implanted and age-matched normal-hearing (NH) children (4-13 years). Results: Children with cochlear implants (CIs) exposed to music performed better than others in stress perception and F0 discrimination. Only this subgroup of implanted children improved with age in word stress perception, intensity discrimination, and improved over time in digit span. Prosodic perception, F0 discrimination and forward digit span in implanted children exposed to music was equivalent to the NH group, but other implanted children performed more poorly. For children with CIs, word stress perception was linked to digit span and intensity discrimination: sentence stress perception was additionally linked to F0 discrimination. Conclusions: Prosodic perception in children with CIs is linked to auditory working memory and aspects of auditory discrimination. Engagement in music was linked to better performance across a range of measures, suggesting that music is a valuable tool in the rehabilitation of implanted children.

TI Auditory network connectivity in tinnitus patients: A resting-state fMRI study SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Tinnitus; fMRI; functional connectivity; resting-state; auditory network ID FUNCTIONAL CONNECTIVITY; PSYCHOMETRIC PROPERTIES; LATERALIZED TINNITUS; HUMAN BRAIN; CORTEX; QUESTIONNAIRE; ACTIVATION AB Objective: Resting-state functional magnetic resonance imaging (fMRI) uncovers correlated activity between spatially distinct functionally related brain regions and offers clues about the integrity of functional brain circuits in people with chronic subjective tinnitus. We chose to investigate auditory network connectivity, adopting and extending previously used analyses methods to provide an independent evaluation of replicability. Design: Independent components analysis (ICA) was used to identify coherent patterns arising from spontaneous brain signals within the resting-state data. The auditory network component was extracted and evaluated. Bivariate and partial correlation analyses were performed on pre-defined regions of bilateral auditory cortex to assess functional connectivity. Study sample: Our design carefully matched participant groups for possible confounds, such as hearing status. Twelve patients (seven male, five female; mean age 66 years) all with chronic constant tinnitus and eleven controls (eight male, three female; mean age 68 years) took part. Results: No significant differences were found in auditory network connectivity between groups after correcting for multiple statistical comparisons in the analysis. This contradicts previous findings reporting reduced auditory network connectivity; albeit at a less stringent statistical threshold. Conclusions: Auditory network connectivity does not appear to be reliably altered by the experience of chronic subjective tinnitus. C1 [Davies, J.; Gander, P. E.; Hall, D.

This study investigates if a further improvement is achieved when using a closed set of consonant-vowel-consonant (CVC) speech items with the same vowel, and/or a low-pass (LP) filtered version of the standard speech-shaped noise. Design: Speech reception thresholds in noise were gathered for the digit triplet, CVC, and CVC_LP test and compared to the high-frequency pure-tone average (PTA). Study sample: 118 noise-exposed workers showing a wide range of high-frequency hearing losses. Results: For the 84 Dutch-speaking participants, the CVC test showed an increased measurement error and a decreased between-subject variation, leading to a weaker correlation with the PTA(2,3,4,6) (R = 0.64) and thus a lower sensitivity compared to the digit triplet test (R = 0.86). However, the use of LP-filtered noise resulted in a sensitivity improvement (R = 0.79 versus R = 0.64) due to the large increase in between-subject spread. Similar trends were found for the 34 French-speaking workers. Conclusions: Using CVC words with the same vowel could not increase the sensitivity to detect isolated high-frequency hearing loss. With LP-filtered noise, test sensitivity improved, but it did not surpass the original digit triplet test.

Design: Hearing aid user guides were assessed using four readability formulae and a standardized tool to assess content and design (SAM - Suitability Assessment of Materials). Study sample: A sample of 36 hearing aid user guides (four user guides from nine different hearing aid manufacturers) were analysed. Results: Sixty nine percent of user guides were rated 'not suitable' and 31% were rated 'adequate' for their suitability. Many scored poorly for scope, vocabulary, aspects of layout and typography, and learning stimulation and motivation. The mean reading grade level for all user guides was grade 9.6 which is too high for older adults. Conclusion: The content, design, and readability of hearing aid user guides are not optimal for older adults and thus may serve as a barrier to successful hearing aid outcomes for this population.

Despite extensive literature from a range of health-care professions that provide description and measurement of patient-centred care, a definition of patient-centredness in audiological rehabilitation is lacking. The current study aimed to define patient-centred care specific to audiological rehabilitation from the perspective of older adults who have owned hearing aids for at least one year. Design: Research interviews were conducted with a purposive sample of older adults concerning their perceptions of patient-centredness in audiological rehabilitation, and qualitative content analysis was undertaken. Study sample: The participant sample included ten adults over the age of 60 years who had owned hearing aids for at least one year. Results: Data analysis revealed three dimensions to patient-centred audiological rehabilitation: the therapeutic relationship, the players (audiologist and patient), and clinical processes. Individualised care was seen as an overarching theme linking each of these dimensions. Conclusions: This study reported two models: the first model describes what older adults with hearing aids believe constitutes patient-centred audiological rehabilitation. The second provides a guide to operationalised patient-centred care. Further research is required to address questions pertaining to the presence, nature, and impact of patient-centred audiological rehabilitation.

Previous research had suggested a link between higher levels of technology use and hearing aid success. Design: General technology use was evaluated using a purposefully developed 25-item questionnaire. Twelve items related to everyday technology use (e. g. DVD player) and 13 related to advanced technology use (e. g. Bluetooth). Study sample: Four groups of older adults with HI participated in the study: (1) non-consulters (n = 49), (2) consulters (n = 62), (3) unsuccessful hearing aid owners (n = 61), and (4) successful hearing aid owners (n = 79). Results: Preliminary analyses revealed a main effect in the use of everyday and advanced technology across the four participant groups. However, it was found that age and living arrangements accounted for most of the variance in reported everyday technology use (p < .030; p = .029, respectively) and age and gender accounted for the variance in reported advanced technology use (p < .001; p = .040, respectively). For everyday technology, an increase in age and living alone were associated with decreased technology use and for advanced technology use, age and female gender were associated with decreased technology use. Conclusions: Although we hypothesized that technology use would be less amongst non-consulters and unsuccessful hearing aid owners, our findings did not support this prediction. Technology use did not vary by group membership once the covariates of age, gender, and living arrangements were accounted for.

Design: In a retrospective study, audiological factors, attitudinal beliefs (as derived from the health belief model), client demographics, psychological factors, and age-related factors were evaluated. Study sample: Participants included 160 individuals, 60 years or older, with unilateral or bilateral hearing impairment (HI), fitted with hearing aids for the first time in the previous two years. Participants were assigned to either an unsuccessful hearing aid owner group (n = 75) or a successful hearing aid owner group (n = 85) based on their self-reported hearing aid use and benefit. Results: A multivariate, binomial logistic regression model indicated five factors associated with group membership: participants who had greater support from significant others; more difficulties with hearing and communication in everyday life before getting hearing aids; more positive attitudes to hearing aids; coupled with greater perceived self-efficacy for advanced handling of hearing aids; or who were receiving more gain from their devices; were more likely to be successful hearing aid owners. Conclusions: These findings highlight the importance of addressing non-audiological factors in order to assist older adults achieve success with hearing aids.

This study investigated audiologists' preferences for patient-centredness and identified factors that explain audiologists' preferences for patient-centredness. Design: All members of the Audiological Society of Australia received two questionnaires: (1) a descriptive questionnaire (e. g. age, gender, place of residence, years in practice, employment characteristics), and (2) a modified patient-practitioner orientation scale (PPOS; Krupat et al, 2000) which measures preferences for two aspects of patient-centredness, sharing and caring. Study sample: In total 663 (46%) audiologists returned both questionnaires fully completed. Results: Mean PPOS scores indicated that audiologists prefer patient-centredness. Linear regression modelling identified that older audiologists, that had practiced longer, and who worked in community education, industrial audiology, or teaching had a significantly greater preference for patient-centredness than their peers. In contrast, audiologists who practiced in a private environment and who worked in the area of assessment of adults had a significantly lesser preference for patient-centredness than their peers. Conclusions: Audiologists prefer client-centredness and age, years of experience, and employment characteristics can partly explain preferences for patient-centredness. Future research should explore the relationships between patient-centredness and intervention outcomes in audiology. C1 [Laplante-Levesque, Ariane] Eriksholm Res Ctr, DK-3070 Snekkersten, Denmark.

Design: A retrospective research design was employed. Participants completed 14 measures, after which two multivariate, multinomial logistic regression models were fitted to the data to determine which factors were associated with consultation for HI and hearing aid uptake. Study sample: Three-hundred-and-seven individuals who were 60 years or older and who presented with a unilateral or bilateral HI participated in the study. Non-hearing aid owners were assigned to a non-consulter group (n = 55) or a consulter group (n = 92); hearing aid owners were assigned to an unsuccessful hearing aid owner group (n = 75) or a successful hearing aid owner group (n = 85). Results: A similar combination of factors was associated with the decisions to consult a health professional about HI and/or to adopt hearing aids. The most important factors related to attitudinal beliefs (e. g. perceived benefits of hearing aids) and external cues to action (e. g. support from significant others). Greater HI also influenced consultation and adoption of hearing aids. Conclusions: Findings highlight the importance of non-audiological factors in hearing rehabilitation to improve consultation for HI and hearing aid adoption.

This study aimed to determine what factors were associated with achieving adequate hearing aid self-efficacy. Design: A retrospective research design was employed wherein hearing aid self-efficacy was the primary outcome. Explanatory variables included personal demographics, visual disability, and experiences related to participants 'hearing ability and hearing aids. Study sample: A total of 307 older adults with hearing impairment participated in the study (147 non hearing aid owners and 160 hearing aid owners). Results: Non-hearing aid owners were more likely to report adequate hearing aid self-efficacy if they reported no visual disability, had experienced hearing loss for longer, reported more positive support from a significant other, and were not anxious about wearing hearing aids. Hearing aid owners were more likely to report adequate hearing aid self-efficacy if they had had a positive hearing aid experience and no visual disability. Conclusions: More research is needed to develop and evaluate intervention approaches that promote optimal levels of hearing aid self-efficacy among older adults with hearing impairment.

The aims of this study were to obtain normative data, and to evaluate the clinical feasibility and predictive value of an Australian version of the ANL test in an older population. Design: Repeated ANL measurements were presented diotically using earphones. All participants provided demographic information and hearing aid owners were asked about their aid use. Study sample: A total of 290 older adults were assessed; 166 participants had a hearing impairment and 96 owned a hearing aid. Results: The mean ANL was lower than previously reported. While age and gender had no effect on ANL, a significant, but weak, correlation was found between ANL and hearing loss. The test-retest reliability showed the results were clinically unreliable. In addition, the ANL did not predict hours or pattern of hearing aid use. Conclusions: While the Australian ANL test showed several similar characteristics to previous versions of the test, low test-retest reliability raised questions about its clinical value as a predictor for long-term hearing aid use.

Design : Participants completed the hospital anxiety and depression scale and completed two cognitive tasks: the Vienna determination task and a variant of the Stroop paradigm. In addition, tinnitus sufferers completed the subjective tinnitus severity scale. Study sample : Thirty-three tinnitus sufferers and 33 controls took part in the study (n = 66). Results : Tinnitus sufferers were no more depressed nor anxious than controls, but they performed less well on both cognitive tasks. Conclusions : Possible causes and implications of these performance decrements are discussed, with particular attention given to the possibility that subjective distress is an important moderating factor in tinnitus sufferers.

Design: Speech perception was assessed using speech reception threshold in noise (SRTn) for sentences and consonant identification in quiet and at different signal-to-noise ratios (15, 10, 5, and 0 dB SNR). Study sample: Ten ANSD listeners and normal-hearing listeners participated in the study. Results: ANSD listeners required significantly higher SRTn when compared to the normal-hearing listeners. Companding reduced SRTn more significantly in listeners with ANSD, but for normal-hearing listeners there was only a marginal reduction. In the consonant identification task, ANSD listeners performed poorer than normal-hearing listeners in quiet and noise. Companding improved consonant identification in quiet and at 15 dB SNR for listeners with ANSD, whereas no improvement was observed in normal-hearing listeners. Conclusion: Results of the present study demonstrate that companding improved speech perception in quiet and noise for ANSD listeners. The amount of improvement is higher at higher SNRs. In normal-hearing listeners, companding showed marginal improvement in both quiet and noise. The findings are discussed for rehabilitation of ANSD listeners by hearing aids which incorporate the companding strategy.

TI A factor analysis of the SSQ (Speech, Spatial, and Qualities of Hearing Scale) SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Psychoacoustics/hearing science; behavioral measures; hearing aids; speech perception ID EXPLORATORY FACTOR-ANALYSIS; BILATERAL COCHLEAR IMPLANTS; CONFIDENCE-INTERVALS; PARALLEL ANALYSIS; FACTOR LOADINGS; SAMPLE-SIZE; AID USERS; BENEFIT; NUMBER; LOCALIZATION AB Objective: The speech, spatial, and qualities of hearing questionnaire (SSQ) is a self-report test of auditory disability. The 49 items ask how well a listener would do in many complex listening situations illustrative of real life. The scores on the items are often combined into the three main sections or into 10 pragmatic subscales. We report here a factor analysis of the SSQ that we conducted to further investigate its statistical properties and to determine its structure. Design: Statistical factor analysis of questionnaire data, using parallel analysis to determine the number of factors to retain, oblique rotation of factors, and a bootstrap method to estimate the confidence intervals. Study sample: 1220 people who have attended MRC IHR over the last decade. Results: We found three clear factors, essentially corresponding to the three main sections of the SSQ. They are termed "speech understanding", "spatial perception", and "clarity, separation, and identification". Thirty-five of the SSQ questions were included in the three factors. There was partial evidence for a fourth factor, "effort and concentration", representing two more questions. Conclusions: These results aid in the interpretation and application of the SSQ and indicate potential methods for generating average scores.

For this reason, a workshop was developed for audiologists interested in expanding their counselling skills. Since one-time workshops typically do not result in changes in practice, this program adopted a distributed-over-time learning model, consisting of 20 hours of participation across six weeks. The extended nature of the program provided multiple opportunities to learn several counselling strategies, and apply and evaluate the effectiveness of these strategies in clinical settings. Design: Learning objectives were assessed throughout the six-week program. However, at the conclusion of each program, it was unknown whether new knowledge carried over into sustained new skills. Therefore, we surveyed attendees six months after their program, to determine if the program had affected changes in their practice. Study sample: Twenty clinicians (response rate +/- 91%) participated in the survey. Results: All respondents made some, and often many, changes in patient communication. They applied several counseling concepts to their work settings and reported positive changes in patient-clinician dynamics. Conclusion: Results suggest that a six-week program is effective in helping clinicians change their counseling skills within their practice.

Design: Prospective pilot study. Study sample: Thirteen adult patients who underwent unilateral cochlear implant surgery were examined with high-resolution rotational tomography after cochlear implantation. All subjects were also tested with VNG, and 12 of the subjects were tested with cVEMP and audiometry before and after surgery. Results: We found that although the electrode was originally planned to be positioned inside the scala tympani, only 8 of 13 had full insertion into the scala tympani. Loss of cVEMP response occurred to the same extent in the group with full scala tympani positioning and the group with scala vestibuli involvement. There was a non-significant difference in the loss of caloric response and residual hearing between the two groups. Interscalar dislocation of the electrode inside the cochlea was observed in two patients. A higher loss of residual hearing could be seen in the group with electrode dislocation between the scalae. Conclusions: Our findings indicate that intracochlear electrode dislocation is a possible cause to loss of residual hearing during cochlear implantation but cannot be the sole cause of postoperative vestibular loss.

Design: Four members of an Iranian deaf family were recruited in this study. The GJB2 coding region and exon-intron boundaries were investigated using direct sequencing. Study sample : The proposita was a 12-year-old girl with congenital non-syndromic hearing loss. She was born to consanguineous parents. The proposita, her parents and deaf maternal uncle were screened for GJB2 mutations. Results: Sequencing demonstrated the presence of the c.176_191del and c.327_328delGGinsA mutations in the proposita, the c.176_191del mutation in her father, and the c.35delG and c.327_328delGGinsA mutations in trans in her apparently unaffected mother as well as in her congenitally deaf uncle. Follow-up pure-tone audiometry revealed moderate to severe mid-and high-frequency hearing loss in the mother. Conclusions: This study shows the complexity of genetic testing and counseling for hearing loss.

The stimuli used were low frequency tone pips calibrated to reference levels derived from ISO 389 values. Design: Tone pips were presented via supra-aural earphones and a B71 Radioear bone vibrator at 0.5 or 1 kHz. ABR thresholds from both transducers were compared at each frequency. Study sample: twenty-seven newborn hearing screening referrals (33 ears) who passed an ABR discharge criterion at 4 kHz. Results: Median air-and bone-conduction ABR threshold differences were 30 dB at 0.5 kHz and 20 dB at 1 kHz. Conclusion: The 0.5 kHz data from this study and previous studies were compared. Previous studies suggested lower figures for the bone-conduction stimulus level correction. Likely sources of this discrepancy are discussed. The average 0.5 kHz bone-conduction correction value for infants <3 months old is about 28 dB. The correction for 1 kHz is 20 dB. We recommend that calibration reference levels used in this study be adopted and that appropriate corrections be applied to bone conduction ABR thresholds in infants <3 months old before calculation of any air-bone gap and subsequent clinical interpretation.

Design: VEMPs and OVEMPs were obtained simultaneously from subjects in supine posture with both head and eyes elevated. Thresholds to ITA were measured using four different response identification methods. Study sample: Twelve adult subjects with no history of auditory or vestibular deficits. Results: VEMP and OVEMP thresholds were found within the range of -8 to -26 dB re 0.2 g, with overall VEMP thresholds being lower than OVEMP thresholds by average of 3-10 dB, depending on the method used. Conclusion: VEMPs can be obtained at lower ITA stimulation levels than OVEMPs. Threshold values depend on the method used to define response presence. C1 [Paillard, Aurore C.; Todd, Neil P.

Design: We measured twelve ANL repetitions, i.e. four complete ANL tests (4 x 3 repetitions), at one session using diotic presentation and a non-semantic ANL version. Study sample: Thirty-two normal-hearing adults. Results: Small order and fatigue effects were seen. We used the coefficient of repeatability (CR) to assess the repeatability; CRs ranged between 3.9 and 7.6 dB for the four ANL tests. Using the twelve ANL repetitions we removed the variability of the ANL across subjects by normalizing the data to the individual mean ANL for the twelve repetitions. The mean normalized ANL across the subjects rapidly approached the ANL normalized to the individual mean for the 12 repetitions (0 dB), and after three repetitions the SD seemed to be stable at about 3 dB. Conclusions: The findings suggest that both order and fatigue affect the ANL. The findings also suggest that it may be more accurate to speak of an acceptable noise range than ANL. These findings have large implications for how we understand acceptable noise and it would explain a large part of the variability seen among normal-hearing and perhaps hearing-impaired subjects.

Design: Listeners were presented speech-perception-in-noise sentences processed at three levels of concurrent multi-talker babble and reverberation. For each condition, 50 sentences with multiple semantic cues and 50 with minimum semantic cues were randomly presented. Listeners verbally reported and wrote down the target words. The metric, k, was derived from percent-correct scores for sentences with and without semantics. Study sample: Ten native and 33 non-native listeners participated. Results: The presence of semantics increased recognition benefit by over 250% for natives, but access to semantics remained limited for non-native listeners (90-135%). The k was comparable across conditions for native listeners, but level-dependent for non-natives. The k for non-natives was significantly different from 1 in all conditions, suggesting semantic cues, though reduced in importance in difficult conditions, were helpful for non-natives. Conclusions: Non-natives as a group were not as effective in using semantics to facilitate English sentence recognition as natives. Poor listening conditions were particularly adverse to the use of semantics in non-natives, who may rely on clear acoustic-phonetic cues before benefitting from semantic cues when recognizing connected speech.

We hypothesised that, among individuals with normal auditory thresholds, the mechanism of frequency selectivity might differ between subjects with and without tinnitus. Our objective was to identify any differences between normal-hearing individuals with tinnitus and those without in terms of psychophysical tuning curves (PTCs) and threshold-equalising noise (TEN) test results. Design: We determined PTCs and performed the TEN test. Study sample: We evaluated 57 individuals, 16 with bilateral tinnitus (tinnitus-group) and 41 without tinnitus (control-group). Results: We found significant differences between tinnitus and control groups regarding the following: 2 kHz PTCs obtained in noise at 6 and 8 kHz; 4 kHz PTCs obtained in noise at 2 and 8 kHz; and 6 and 8 kHz PTCs obtained in noise at 2 and 3 kHz. The TEN test revealed differences between groups in terms of auditory thresholds, which were significantly higher in the tinnitus group. In addition, none of the individuals in the tinnitus group were found to have dead regions in the cochlea. Conclusions: Despite having normal auditory thresholds, individuals with tinnitus have auditory patterns that differ significantly from those seen in individuals without tinnitus, such differences being suggestive of cochlear impairment.

Design: This was achieved by studying the correlation between (1) phoneme identification in quiet and in a steady-state or fluctuating (8 Hz) noises, and (2) amplitude-modulation detection thresholds (MDTs) at 8 Hz (i.e. slow temporal modulations). Study sample: Twenty-one CI users, unilaterally implanted with the same device, were tested in free field with their everyday clinical processor. Results: Extensive variability across subjects was observed for both phoneme identification and MDTs. Vowel and consonant identification scores in quiet were significantly correlated with MDTs at 8 Hz (r= -0.47 for consonants, r= -0.44 for vowels; p < 0.05). When the masker was a steady-state noise, only consonant identification scores tended to correlate with MDTs at 8 Hz (r= -0.4; p = 0.07). When the masker was a fluctuating noise, consonant and vowel identification scores were not significantly correlated with MDTs at 8 Hz. Conclusions: Sensitivity to slow amplitude modulations is correlated with vowel and consonant perception in CI users. However, reduced sensitivity to slow modulations does not entirely explain the limited capacity of CI recipients to understand speech in noise. C1 [Gnansia, Dan] Neurelec, F-06224 Vallauris, France.

Design: Three experimental steps were carried out: (1) a perceptual optimization of the recorded materials, (2) an evaluation in normal-hearing (NH) listeners, and (3) a validation in CI-users. Measurements were performed both in quiet and in noise. Study sample: Forty-four NH subjects and six CI-users participated. Results: After selecting the sentences with a similar intelligibility, the reference psychometric curve for NH listeners was determined, showing steep slopes for measurements in quiet (12.3%/dB) and in noise (18.7%/dB), similar to the LIST with female voice. The 38 lists of 10 sentences yielded equal scores, and the within-subject test-retest reliability was high (1.7 dB in quiet, 1.1 dB in noise). For the CI-users, parallel psychometric curves were found between the LIST with male and female voice. Conclusions: The LIST-m is a reliable and valid speech intelligibility test that can be used for CI-users, both in quiet and in noise.

Design: A population-based, longitudinal study was performed on outcomes of children with hearing impairment (LOCHI) in Australia. The demographic characteristics of the children were described, and their developmental outcomes were evaluated at three years of age. Performance of children with ANSD was compared with that of children without ANSD in the LOCHI study. Study sample: There were 47 children with ANSD in the study sample. Results: Sixty-four percent of children with ANSD have hearing sensitivity loss ranging from mild to severe degree, and the remaining have profound hearing loss. At three years, 27 children used hearing aids, 19 used cochlear implants, and one child did not use any hearing device. Thirty percent of children have disabilities in addition to hearing loss. On average, there were no significant differences in performance level between children with and without ANSD. Also, the variability of scores was not significantly different between the two groups. Conclusions: There was no significant difference in performance levels or variability between children with and without ANSD, both for children who use hearing aids, and children who use cochlear implants.

Design: Children born between 2002 and 2007 who were identified with hearing loss and received audiological intervention by 3 years of age in Australia enrolled in the study. Their demographic characteristics are described. Study sample: Four hundred and fifty-one children in New South Wales, Victoria, and Southern Queensland. Results: Data on age at first hearing-aid fitting for different degrees of hearing loss are reported together with demographic characteristics of the cohort. Conclusion: A unique environment in Australia where all children with varied access to universal newborn hearing screening received the same consistent hearing services from a national hearing service provider makes it possible to investigate the effects of access to early auditory intervention on children's outcomes at a population level.

Design and study sample : A randomized controlled design was implemented as part of a population-based, longitudinal study on outcomes of children with hearing impairment (LOCHI) in Australia. Two hundred and eighteen children were randomly assigned to either the NAL or the DSL prescription for first fitting of hearing aids. Their performance outcomes were evaluated. Results: Prescriptive targets were closely matched in children's hearing aids. There were no significant differences in children's language, speech production, or functional performance between prescriptions. Parents' ratings of children's device usage and loudness discomfort were not significantly different between prescription groups. Functional performance within the first year of fitting together with degree of hearing loss, presence of additional disabilities, and maternal education explained 44% of variation in language ability of children by three years of age. Conclusions: There was no significant association between choice of hearing-aid prescription and variance in children's outcomes at three years of age. In contrast, additional disability, maternal educational level, and early functional performance were significant predictive factors of children's outcomes. C1 [Ching, Teresa Y.

Design: A randomized controlled trial was conducted as part of the population-based longitudinal study on outcomes of children with hearing impairment (LOCHI). Participants were randomly assigned to fitting with NLFC (Phonak Naida V SP or UP) or with conventional processing in hearing aids, prescribed by using either the NAL or the DSL formula. Standardized tests of speech production, receptive and expressive language were administered, and parent ratings were collected. All assessments were double-blinded. Study sample: Participants were 44 of the 450 children in the LOCHI cohort. Results: Compared to children using conventional processing, receptive and expressive language was higher but receptive vocabulary and consonant articulation scores were lower for children who use NLFC. There was increased substitution of affricates by fricatives for children using NLFC, compared to children using conventional amplification. After allowing for the effect of multiple demographic variables, the difference in global language scores between groups was not significant (effect: 0.8 [95% confidence interval: -6.7, 8.3]). Conclusions: There is insufficient evidence to indicate a difference in language ability between children using NLFC and those using conventional amplification. C1 [Ching, Teresa Y.

Design: A between-group comparison of speech intelligibility index (SII) and loudness, based on hearing aids fitted according to NAL-NL1, DSL v4.1, or DSL m[i/o] prescriptions. A within-group comparison of gains prescribed by DSL m[i/o] and NAL-NL2 for children in terms of SII and loudness. Study sample: Participants were 200 children, who were randomly assigned to first hearing-aid fitting with either NAL-NL1, DSL v4.1, or DSL m[i/o]. Audiometric data and hearing-aid data at 3 years of age were used. Results: On average, SII calculated on the basis of hearing-aid gains were higher for DSL than for NAL-NL1 at low input level, equivalent at medium input level, and higher for NAL-NL1 than DSL at high input level. Greater loudness was associated with DSL than with NAL-NL1, across a range of input levels. Comparing NAL-NL2 and DSL m[i/o] target gains revealed higher SII for the latter at low input level. SII was higher for NAL-NL2 than for DSL m[i/o] at medium-and high-input levels despite greater loudness for gains prescribed by DSL m[i/o] than by NAL-NL2. Conclusion: The choice of prescription has minimal effects on speech intelligibility predictions but marked effects on loudness predictions. C1 [Ching, Teresa Y.

TI Hearing-aid safety: A comparison of estimated threshold shifts for gains recommended by NAL-NL2 and DSL m[i/o] prescriptions for children SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing-aid safety; threshold shift; hearing-aid prescription; children; NAL-NL2; DSLm[i/o] ID TEMPORARY; NOISE AB Objective: To investigate the predicted threshold shift associated with the use of nonlinear hearing aids fitted to the NAL-NL2 or the DSL m[i/o] prescription for children with the same audiograms. For medium and high input levels, we asked: (1) How does predicted asymptotic threshold shifts (ATS) differ according to the choice of prescription? (2) How does predicted ATS vary with hearing level for gains prescribed by the two prescriptions? Design: A mathematical model consisting of the modified power law combined with equations for predicting temporary threshold shift (Macrae, 1994b) was used to predict ATS. Study sample: Predicted threshold shift were determined for 57 audiograms at medium and high input levels. Results: For the 57 audiograms, DSL m[i/o] gains for high input levels were associated with increased risk relative to NAL-NL2. The variation of ATS with hearing level suggests that NAL-NL2 gains became unsafe when hearing loss >90 dB HL. The gains prescribed by DSL m[i/o] became unsafe when hearing loss >80 dB HL at a medium input level, and >70 dB HL at a high input level. Conclusion: There is a risk of damage to hearing for children using nonlinear amplification. Vigilant checking for threshold shift is recommended. C1 [Ching, Teresa Y.

Design: A population-based prospective cohort study; with randomized controlled trials of hearing aid prescription and non-linear frequency compression. Sample: 451 children in New South Wales, Victoria and Southern Queensland. Results: Significant predictors of language outcomes at 3 years of age included severity of hearing loss, gender, presence of additional disabilities, maternal education, and age at cochlear implantation. Although prescription did not have a significant effect on outcomes, its influence on loudness and hearing aid safety has implications for management. After controlling for a range of predictor variables, nonlinear frequency compression did not have a significant effect on outcomes. For the same hearing sensitivity, the presence of auditory neuropathy did not have a significant effect on outcomes. Conclusions: These findings form the basis for evidence-based guidelines for management of children with hearing loss. C1 [Ching, Teresa Y.

Design: Based on the analysis of informal parent discussion groups, four open-ended questions were formulated to solicit information about parents' expectations following diagnosis, as well as experiences and challenges when raising a child with a hearing loss. Study sample: Forty parents of children, aged between three to five years, who were diagnosed with hearing loss before the age of three years. Results: Parents' responses revealed strong support for early intervention, high expectations for their child's development, and desire for information tailored to individual needs. Parents also reported anxiety relating to their perceptions of the significance of consistent device usage on their child's development. Further concerns arose from their observations of the difficulties experienced by their child in real-world environments despite consistent device usage, and their perception of their child's language delay despite early intervention. Conclusions: The findings point to a need to support parents to form realistic expectations based on current knowledge. Implications for clinicians to provide improved management of children with hearing loss are discussed. C1 Hearing Cooperat Res Ctr, Melbourne, Vic, Australia.

TI D-methionine pre-loading reduces both noise-induced permanent threshold shift and outer hair cell loss in the chinchilla SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Noise-induced hearing loss; otoprotection; pre-loading; methionine ID INDUCED HEARING-LOSS; FREE-RADICALS; INNER-EAR; ACOUSTIC OVERSTIMULATION; GUINEA-PIG; PREVENTION; PROTECTION; EXPOSURE; COCHLEA; GLUTATHIONE AB Objective: This study tested multiple dosing epochs of pre-loaded D-methionine (D-met) for otoprotection from noise-induced hearing loss (NIHL). Design: Auditory brainstem response (ABR) thresholds were measured at baseline, 1 day, and 21 days following a 6-hour 105 dB sound pressure level (SPL) octave band noise (OBN) exposure. Outer hair cell (OHC) counts were measured after day 21 sacrifice. Study sample: Three groups of five Chinchillas laniger each were given a 2-day regimen comprising five doses of D-met (200 mg/kg/dose) intraperitoneally (IP) starting 2, 2.5, or 3 days prior to noise exposure. A control group (n = 5) received five doses of equivalent volume saline IP starting 2.5 days prior to noise exposure. Results: ABR threshold shifts from baseline to day-21 post-noise exposure were reduced in all D-met groups versus controls, reaching significance (p < 0.05) in the 3-day group. D-met groups showed reduced OHC loss relative to controls at day-21 post-noise exposure, reaching significance (p < 0.05) at all frequency regions in the 3-day group and at the 2, 4, and 8 kHz frequency regions in the 2.5-day group. Conclusions: D-met administration in advance of noise-exposure, without further administration, significantly protects from noise-induced ABR threshold shift and OHC loss.

The present study assessed the discrimination of differences in F0 contour peak alignment by adolescent users of cochlear implants (CIs). Design: In Experiment 1, subjects discriminated between rise-fall F0 contours located early in the syllable and those aligned late. Recorded utterances with manipulated F0 were used as stimuli and all subjects wore a unilateral CI. In Experiment 2, bilaterally-implanted subjects repeated Experiment 1 in the bilateral condition. Study sample: Twenty-one CI users aged 12-21 years participated. A normally-hearing control group (n = 20) also completed Experiment 1. Results: Listeners with normal hearing (NH) could discriminate between F0 peaks differing by 80 ms or more. Results varied among the CI users, with only four users displaying a pattern of results similar to that of the NH listeners. Sixteen CI users responded inconsistently or at chance levels (p > 0.05; binomial test). Ten CI users who were bilaterally implanted completed the tests in unilateral and bilateral listening conditions. Conclusions: Results suggest that CI users may have difficulty discriminating between F0 alignment and that use of bilateral implants did not provide an advantage to discrimination.

TI Prevalence of hearing loss in patients with late-onset Pompe disease: Audiological and otological consequences SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Late-onset Pompe disease; glycogenosis type II; stapedial reflex; hearing threshold; residual noise AB Objective: The metabolic disorder Pompe disease mainly affects the skeletal muscle in adults. The hearing impairment due to stapedius muscle involvement in adult patients is not known. Design : The frequency, severity, and type of hearing impairment was characterized prospectively using pure-tone audiometry, tympanometry, stapedial reflexes, otoacoustic emissions, and brainstem-evoked response audiometry in adult patients on enzyme replacement therapy for genetically confirmed Pompe disease. Study sample: 11 adult patients (median age: 47 years, range: 22-71). Results: Four patients complained about subjective hearing disturbances. Using World Health Organization definition of hearing impairment, abnormal hearing thresholds resulting in mild hearing loss were found in 36% of patients. Compared to normative data (ISO 7029), the hearing threshold was below the median in all but three ears. Stapedial reflexes could not be elicited ipsilateral in 18% and contralateral in 36%. Auditory brainstem responses showed no retrocochlear pathology. Conclusions: The prevalence of hearing loss slightly exceeded the normative data of the general population. Consistent with previous studies the hearing impairment was usually mild. The percentage of pathological stapedial reflexes exceeded that of matched control subjects and suggests a selective involvement of the stapedius muscle, potentially as a sequela of Pompe disease.

Its weak amplitude often prevents its measurement with a high signal-to-noise ratio (SNR). Recording of FFR using multichannel EEG is possible but expensive and it involves the manual screening of raw data. Design: We describe a new method to extract FFR features by prescreening the raw data using automatic monitoring of sound pressure in the ear canal. Removal of stimulus artifacts, noise reduction, and data selection were systematically studied. Study sample: The reliability of our new method was tested by comparing FFRs tracking accuracy and pitch perception in fifteen individuals with normal hearing. Results: The extracted FFRs tracking accuracy was significantly correlated with behavioral measures of pitch perception, indicating that FFR could be used to represent individual differences in pitch perception ability among a population with similar hearing characteristics. Conclusion: The designed system could extract FFR signals more accurately with high SNR after signal prescreen and noise reduction.

Decade audiograms were also compared among two groups of affected subjects with different mutations of USH2A. Design: DNA samples from patients with Usher syndrome type II were analysed. The audiological features of patients and affected siblings with USH2A mutations were also examined to identify genotype-phenotype correlations. Study sample : Genetic and audiometric examinations were performed in 18 subjects from nine families with Usher syndrome type IIA. Results: Three different USH2A mutations were identified in the affected subjects. Both similarities and differences of the auditory phenotype were seen in families with several affected siblings. A variable degree of hearing loss, ranging from mild to profound, was observed among affected subjects. No significant differences in hearing thresholds were found the group of affected subjects with different pathological mutations. Conclusions: Our results indicate that mutations in the USH2A gene and the resulting phenotype are probably modulated by other variables, such as modifying genes, epigenetics or environmental factors which may be of importance for better understanding the etiology of Usher syndrome.

To investigate the performance benefits up to one year post-implantation in terms of speech recognition, sound quality, and quality of life. Design: Prospective, with sequential enrolment and within-subject comparisons. Postoperative performance using a Freedom Hybrid sound processor was compared with that of pre-operative hearing aids. Study sample: Sixty-six adult hearing-impaired subjects with bilateral severe-to-profound high frequency hearing loss. Results: Group median increase in air-conduction thresholds in the implanted ear for test frequencies 125-1000 Hz was <15 dB across the population; both immediately and one year post-operatively. Eighty-eight percent of subjects used the Hybrid processor at one year post-op. Sixty-five percent of subjects had significant gain in speech recognition in quiet, and 73% in noise (>= 20 percentage points/2 dB SNR). Mean SSQ subscale scores were significantly improved (+1.2, +1.3, +1.8 points, p < 0.001), as was mean HUI3 score (+0.117, p < 0.01). Combining residual hearing with CI gave 22-26 %age points mean benefit in speech recognition scores over CI alone (p < 0.01). Conclusions: Useful residual hearing was conserved in 88% of subjects. Speech perception was significantly improved over preoperative hearing aids, as was sound quality and quality of life. C1 [Lenarz, Thomas] MHH, Hannover, Germany.

Design: Normative study. Study sample: The study was conducted to obtain oVEMP responses from 54 healthy individuals in age range of 18-30 years. The responses were acquired for tone-bursts at octave and mid-octave frequencies from 250 to 2000 Hz from the inferior oblique muscle using contralateral electrode placement. The frequencies were compared for amplitude and threshold. Results: oVEMPs were present in 100% of individuals at or below the frequency of 1000 Hz. The responses had maximum amplitude and lowest thresholds at 500 Hz. There were at least two replicable peak-complexes namely n1-p1 and p1-n2. Both these complexes revealed tuning at 500 Hz. Comparison between the two peak-complexes revealed higher amplitudes and lower thresholds for p1-n2 complex. Conclusions: oVEMPs are tuned to 500 Hz for both peak-complexes, with p1-n2 being more robust. Future studies using the threshold of oVEMP may be better suited to use p1-n2 complex for this purpose, provided vestibular origin of the second complex is proved. Additionally, careful use of tuning property is recommended when evaluating pathological conditions.

Design: Cross-sectional within a comparative study of subjects. Study sample: Subjects were 325 first-grade and second-grade children (6-10 years old) from primary schools in Shenzhen, China. Results: Using the conventional pure-tone screening test with the pass/refer criterion set as 25 dB HL, as the "gold standard ", the sensitivity and specificity of the automated hearing screening test was 0.63 and 0.82, respectively. No specific pattern in the failure rates was observed to relate to the students' grade. There was no statistically significant age effect or gender effect. Conclusions: The results suggest that with further improvement in terms of its sensitivity and specificity, it may be feasible to use the automated hearing screening test system to conduct routine school hearing screenings.

The often-used sequential test strategy saves time, but the multiple testing increases the probability of falsely detected responses. Therefore, the critical test value must guarantee the specified error probability for the maximum test step number. However, response detection at all lower test step numbers is disadvantaged. We propose calculating the critical test values for each test step number, which correspond exactly to the given error probability. Design: The critical test values for each test step were calculated by the method described by Sturzebecher et al (2005). A table with the test values was implemented with customized software of the Eclipse ASSR system (R) (Interacoustics, Denmark). Study sample: Table-related testing was performed on a sample of raw EEG data collected during the routine clinical measurement of frequency-specific auditory steady-state responses (ASSR) for hearing threshold assessment. Results: The new test strategy leads to a significantly increased detection rate and a significantly shorter detection time. Conclusions: The new test strategy can improve the performance of the objective hearing threshold assessment and of the newborn hearing screening.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Age-related hearing loss (ARHL); epidemiology; cohort; generational study ID GENERATIONAL-DIFFERENCES; ADULT-POPULATION; THRESHOLD LEVELS; PREVALENCE; IMPAIRMENT; MORTALITY AB Objective: The state of hearing in 75-year old persons was measured in a population based epidemiological study with the aim of studying if hearing had changed during a time span of 29 years. Design: An epidemiological study of generational effects in three age cohorts. Study sample: Three age cohorts were included: cohort 1 (n: 267) born in 1976-77, cohort 4 (n: 197) in 1990-91, and cohort 6 (n: 570) in 2005. The same test procedures using pure-tone audiometry and a short questionnaire were applied to the three cohorts of 75-year old residents in the same city. Results: The hearing was essentially unchanged during the span of the investigation-almost three decades. Low-frequency hearing was up to about 10 dB poorer in the most recently studied cohort compared to the previously studied cohorts. The reason for this difference is considered to depend on methodological factors. Self-assessed hearing and tinnitus was mainly unchanged, or had minor changes both to the better and to the worse. Conclusions: The hearing, both measured with pure-tone audiometry and with a short questionnaire, of 75-year old persons has not changed at all, or only marginally, over three decades.

Design: The BHIs of Australian war veterans were calculated from their hearing threshold levels (HTLs) and compared with their scores on a hearing questionnaire, the hearing measurement scale (HMS). Study sample: The HTLs of 282 Australian war veterans were measured at frequencies from 0.25 to 8 kHz and scores on the HMS were obtained from 154 of those veterans. Results: No grounds could be found for altering the frequencies included in the average HTL or the high fence of 92 dB HL used in calculating the monaural hearing impairments (MHIs) of the veterans, and no grounds could be found for altering the ratio of 5: 1 used in determining the BHI from the MHIs of the better and worse ears. However, agreement between HMS score and BHI was improved by reducing the low fence used in calculating MHI from 25 to 15 dB HL. Conclusion: A modified version of BHI provided an improved procedure for estimating severity of hearing loss from audiograms but would not be suitable for compensation purposes. C1 [Macrae, J.

Design: Prospective cohort study. Study sample: Analysis of 100 unrelated Brazilian patients with severe to profound bilateral SNHL submitted to cochlear implant (CI) between 2002 and 2010 at the University of Campinas hospital. The study was based upon three groups: individuals with congenital, progressive, and sudden SNHL. Results: After the diagnostic investigation, the number of cases with unknown etiology was reduced from 72 to 42 (a 42% reduction); 25% of cases were due to environmental factors, 19% to genetic causes, and 14% to inner-ear abnormalities or other clinical features. The genetic and imaging findings contributed to the diagnosis of SNHL in 19% and 20% of the cases analysed, respectively. Molecular testing mainly contributed to the diagnosis of patients with congenital SNHL, while the contribution of radiologic examination was higher for individuals with progressive or sudden SNHL. A sequential diagnostic protocol was proposed based on these data. Conclusions: The proposed diagnostic workup algorithm could provide better optimization of etiologic diagnosis, as well as reduced costs, compared to a simultaneous testing approach.

TI Using response time to speech as a measure for listening effort SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Listening effort; speech perception; speech in noise; digits ID NORMAL-HEARING; NOISE; ENHANCEMENT; PERFORMANCE; CHILDREN; TASKS; EASE AB Objective: Speech signals that do not differ in intelligibility might differ in listening effort. This study aimed to investigate the effect of background noise on response time to intelligible speech. Design: We added various amounts of stationary noise to spoken digit triplets and measured the influence of noise on the response time for both an identification and an arithmetic task: Task 1 'identify the final digit in a triplet', and Task 2 'calculate the sum of the initial and the final digits in a triplet.' Study sample: Twelve normal-hearing participants with a mean age of 30.6 years (range: 28-44 years). Results: Response time increased with lower (i.e. worse) signal to noise ratios for both tasks, even for signal to noise ratios with almost maximum intelligibility (close to 100%). The response time during the arithmetic task was more affected by the noise than during the identification task, but the arithmetic task demonstrated higher variance. Conclusions: The response time to digit triplets reduces significantly for increasing signal to noise ratios, even where speech intelligibility is optimal.

Design: Unaided ANLs were measured pre-hearing-aid fitting. Hearing-aid success was assessed three months post-fitting using the international outcome inventory for hearing aids (IOI-HA) and a hearing-aid use questionnaire. Study sample: Eighty adults with hearing impairment completed the study. Results: Both Taiwanese and ISTS ANLs were significantly associated with hearing-aid success, with higher ANLs suggesting poorer outcomes. However, the ANL's prediction accuracy for the probability of hearing-aid success was either much lower than that suggested by some literature, or was not much different from that of simply predicting all listeners as successful users. Conclusions: The current study suggested the possibility of using ANL to predict hearing-aid success. However, the usefulness of ANL as a clinical tool is unlikely to be as great as indicated by the literature.

ELSTs of all sizes can cause irreversible hearing loss which can, however, be prevented through early diagnosis and treatment. We aim to emphasize the challenges of prophylactic ELST screening and to explore the role of audiometry in pre-symptomatic ELST screening. Design: For a period of 17 years our patient was screened for ELSTs with inner-ear MRI (magnetic resonance imaging), audiometry, and clinical interviews. Study sample: A male vHL patient who became deaf in one ear due to a radiologically undetectable ELST. Results: Despite annual MRIs, the ELST was not visible until four months after onset of deafness when it appeared as a 1.4 x 1.4 mm tumor mass. Although his hearing was objectively within normal limits for the first 14 years, a distinct pattern of low-frequency hearing loss could retrospectively be seen at all audiometries. Conclusions: Audiometry is a candidate screening tool for detection of non-symptomatic pre-MRI-visible ELSTs, and we have initiated an international collaborative study to further determine its application. At present, we suggest an ELST screening protocol of yearly audiological assessment and inner ear MRI.

Design: The primary research method of this single case study was qualitative interviewing drawing on a narrative approach to elicit the parents' perspectives about their experiences over time. Each parent was interviewed separately, but thematic analyses were undertaken both within and across interviews in order to identify overlaps and differences. Study sample: Participants included the parents of a five-year old child with severe-profound hearing loss, cochlear nerve deficiency, and bilateral common cavities who had received a CI at the age of 18 months. Results: Four themes were identified across the four narrative stages that emerged from the parents' accounts of their experiences regarding their daughter's CI. Themes included hope and despair, questioning professionals' motivations, does deafness need a cure, and bringing the child into the family. Although these themes emerged from both parents' accounts, each parent expressed different perspectives and insights within them. Conclusions: Findings highlight the central place of parental needs and perspectives in decision-making regarding a CI, particularly in the context of uncertain outcomes.

TI Pure-tone audiometric threshold assessment with in-ear monitoring of noise levels SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiometry; octave band measurements AB Objective: Our objective was to obtain reliable threshold measurements without a sound booth by using a passive noise-attenuating hearing protector combined with in-ear 1/3-octave band noise measurements to verify the ear canal was suitably quiet. Design: We deployed laptop-based hearing testing systems to Tanzania as part of a study of HIV infection and hearing. An in-ear probe containing a microphone was used under the hearing protector for both the in-ear noise measurements and threshold audiometry. The 1/3-octave band noise spectrum from the microphone was displayed on the operator's screen with acceptable levels in grey and unacceptable levels in red. Operators attempted to make all bars grey, but focused on achieving grey bars at 2000 Hz and above. Study sample: 624 adults and 197 children provided 3381 in-ear octave band measurements. Repeated measurements from 144 individuals who returned for testing on three separate occasions were also analysed. Results: In-ear noise levels exceeded the maximum permissible ambient noise levels (MPANL) for ears not covered, but not the dB SPL levels corresponding to 0 dB HL between 2000-4000 Hz. In-ear noise measurements were repeatable over time. Conclusions: Reliable audiometry can be performed using a passive noise-attenuating hearing protector and in-ear noise measurements.

TI Hearing-aid users' voices: A factor that could affect directional benefit SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aid; directional microphone; voice ID OLDER-ADULTS; VISUAL CUES; MICROPHONE; PREFERENCE; TECHNOLOGIES; IMPACT; TESTS; NOISE AB Objective: Backward-facing directional processing (Back-DIR) is an algorithm that employs an anti-cardioid directivity pattern to enhance speech arriving from behind the listener. An experiment that was originally designed to evaluate Back-DIR, together with its follow-up experiment, are reported to illustrate how hearing-aid users' voices could affect directional benefit. Design: Speech recognition performance was measured in a speech-180 degrees/noise-0 degrees configuration, with aids programmed to Back-DIR enabled or omnidirectional processing. In the original experiment, the conventional hearing-in-noise test (HINT) was used, wherein listeners repeated heard sentences. In the follow-up experiment, a modified HINT was used, wherein a carrier phrase was presented before each sentence. Study sample: Fifteen adults with sensorineural hearing loss participated in both experiments. Results: Significant Back-DIR benefit (relative to omnidirectional processing) was observed in the follow-up experiment, while not in the original experiment. Conclusions: In the original experiment, hearing aids were affected by listeners' voices such that Back-DIR was not always activated when the target speech was presented. In the follow-up experiment, listeners' voice effects were eliminated by the carrier phrase activating Back-DIR before the sentences were presented. The results suggest that the effect of hearing-aid technologies is highly dependent on the characteristics of listening conditions.

Design: Speech-in-noise performances were measured using BKB sentences presented in diffuse babble-noise, using morphemic scoring. Target of the algorithm was a test-retest standard deviation of 1.13 dB within the presentation of 32 sentences. Normal-hearing participants completed repeated measures using manual administration targeting 50% correct, and the automated procedure targeting 25%, 50%, and 75% correct. Aided hearing-impaired participants completed testing with the automated procedure targeting 25%, 50%, and 75% correct, repeating measurements at the 50% point three times. Study sample: Twelve normal-hearing and 63 hearing-impaired people who had English as first language. Results: Relative to the manual procedure, the algorithm produced the same speech reception threshold in noise (p = 0.96) and lower test-retest reliability on normal-hearing listeners. Both groups obtained significantly different results at the three target points (p < 0.04) with observed reliability close to expected. Target accuracy was not reached within 32 sentences for 18% of measurements on hearing-impaired participants. Conclusions: The reliability of the algorithm was verified. A second test is recommended if the target variability is not reached during the first measurement. C1 Natl Acoust Labs, Sydney, NSW, Australia. Hearing CRC, Sydney, NSW, Australia.

This study investigates effects of uncontrollable parameters in domestic self-screening, such as presentation level and transducer type, on speech reception thresholds (SRTs) obtained with Earcheck. Design: Subjects performed 26 Earchecks that differed regarding presentation level (65, 71, and 77 dBA), presentation mode (monotic or diotic), and masking noise (two different low-pass filtered noises) in the lab. To investigate effects of test environment, participants conducted eight additional Earchecks at home using different transducer types (headphones or loudspeakers). Study sample: Thirty noise-exposed workers, either normal-hearing (n = 10), or with different degrees of NIHL (n = 20), participated. Results: There was a minor effect of presentation levels exceeding 65 dBA in severely impaired listeners. Diotic presentation mode yielded lower SRTs compared to monotic presentation mode. Normal-hearing test results at home were poorer than in the laboratory, whereas hearing-impaired subjects performed better in domestic testing. Using loudspeakers deteriorated SRTs significantly in comparison to headphones, but only in hearing-impaired subjects. Conclusions: A monotic presentation mode using headphones is recommended for domestic screening. Since domestic testing affects SRT results, a follow up study using a large study population should assess Earcheck's validity when performed at home. C1 [Leensen, Monique C.

TI Qualitative interviews on the beliefs and feelings of adults towards their ownership, but non-use of hearing aids SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing loss; hearing-aid non-use; qualitative research ID HELP-SEEKING; OF-LIFE; IMPAIRMENT; SATISFACTION; AUDIOLOGY AB Objective: Up to a quarter of the adults who own hearing aids never use them. To provide these 'non-users' with the best help, hearing care professionals need to have an in-depth understanding of the non-users' beliefs and feelings with regard to the non-use. This qualitative study explored these beliefs and feelings in order to increase our understanding of hearing aid non-users. Design: Individual face-to-face semi-structured interviews were completed. Study sample: Eleven hearing aid owners (aged 54-80 years) who reported that they never or hardly ever used their hearing aids. Results: The participants expressed a variety of feelings towards their non-use, including indifference, self-annoyance, frustration, powerlessness, shame, and guilt. Their feelings were related to beliefs about: (1) the severity of their hearing handicap with and without hearing aids, (2) whom or what was responsible for the non-use, and (3) the attitudes of significant others towards the non-use. Conclusions: Hearing-aid non-users differ in their beliefs and feelings towards the non-use. A patient-centred approach is needed. C1 [Linssen, Anouk M.; Anteunis, Lucien J.

TI Preliminary comparison of bone-anchored hearing instruments and a dental device as treatments for unilateral hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Unilateral hearing loss; single-sided deafness; bone conduction; bone-anchored hearing device; speech perception; sound localization ID SINGLE-SIDED DEAFNESS; INNER-EAR DEAFNESS; IMPAIRED LISTENERS; COMPRESSION SPEED; CONDUCTION DEVICE; HIGH-FREQUENCIES; LOCALIZATION; BAHA; AID; OUTCOMES AB Objective: To compare the effectiveness of two types of treatment for unilateral hearing loss (UHL), bone-anchored hearing instruments (BAHI) and a dental device (SoundBite). Design: Either BAHI or SoundBite were worn for 30 days, and then the devices were swapped and the second device was worn for 30 days. Measures included unaided and aided sound-field thresholds, sound localization, and perception of speech in babble. The APHAB questionnaire was administered for each trial period. Study sample: Nine adult BAHI wearers with UHL. Results : Mid-frequency aided thresholds were lower for SoundBite than for BAHI. Both devices gave benefits for localization after 30 days, but there was no difference between devices. Speech perception was better for both devices than for unaided listening when the target speech came from the poorer hearing side or in front, and the interfering babble came from the better-hearing side. There was no consistent difference between devices. APHAB scores were better for SoundBite than for BAHI. Conclusions : Speech perception and sound localization were similar for the two types of device, but the SoundBite led to lower aided thresholds and better APHAB scores than the BAHI.

TI Assessment of auditory processing disorder in children using an adaptive filtered speech test SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiology; auditory processing disorder; speech perception; hearing disorders; speech acoustics ID TEMPORAL CUES; LANGUAGE; INTELLIGIBILITY; DISCRIMINATION; RECOGNITION; PERCEPTION AB Objective: One type of test commonly used to assess auditory processing disorder (APD) is the 'filtered words test' (FWT), in which a monaural, low-redundancy speech sample is distorted by using filtering to modify its frequency content. One limitation of the various existing FWTs is that they are performed using a constant level of low-pass filtering, making them prone to ceiling and floor effects that compromise their efficiency and accuracy. A recently developed computer-based test, the University of Canterbury Adaptive Speech Test-Filtered Words (UCAST-FW), uses an adaptive procedure intended to improve the efficiency and sensitivity of the test over its constant-level counterparts. Design: The UCAST-FW was administered to school-aged children to investigate the ability of the test to distinguish between children with and without APD. Study sample: Fifteen children aged 7-13 diagnosed with APD, and an aged-matched control group of 10 children with no history of listening difficulties. Results : Data obtained demonstrates a significant difference between the UCAST-FW results obtained by children with APD and those with normal auditory processing. Conclusions: These findings provide evidence that the UCAST-FW may discriminate between children with and without APD with greater sensitivity than its constant-level counterparts.

The study was aimed at finding an optimum repetition rate for the chirp stimulus that facilitates a short response detection time in the frequency domain. Design: Chirp-evoked ABR were recorded at six different stimulation rates between 20/s and 100/s. The stimulation level was 35 dB nHL. The mean harmonic related SNR was calculated, and the response detection time and rate were assessed using a detection algorithm. Study sample: A group of 80 sleeping and 27 awake newborns with normal hearing were included. Results: The highest mean harmonic-related SNR in both groups was found at 60/s. The signal-to-noise ratio (SNR) was significantly smaller for the awake newborns. A significantly shorter detection time can be achieved for both newborn groups at 60/s compared to the other rates tested. Response detection in the group of awake newborns profited more from the change to 60/s compared to the sleeping newborns. Conclusions: It can be expected that with this optimized stimulus paradigm a shorter test time and a higher specificity of the hearing screening can be reached.

Design: ABR to click stimuli at 40 dB nHL were simultaneously recorded from two electrode configurations, ipsilateral mastoid to high forehead (Mi-Fh) and nape to high forehead (N-Fh), with two EEG rejection levels (+/- 5 mu V and +/- 10 mu V). Stimulus rates were between 39.1 and 69.1 per second. Efficiency was measured by confidence in the ABR for a given test time. Study sample: Thirty babies who had passed a targeted newborn hearing screen with ABR thresholds < 40 dB nHL. Results: The N-Fh configuration, as expected, gave on average a larger response amplitude compared to the Mi-Fh configuration but was only marginally significantly better in terms of test efficiency. There was no significant effect of stimulus rate on test efficiency between 39.1/s and 59.1/s. The lower +/- 5 mu V EEG rejection level was more test efficient. Conclusions: This study provides some evidence that, for ABR threshold testing in babies, alternatives of ipsilateral mastoid or nape electrode and a range of stimulus rates have little or no effect on test efficiency. The results support the use of low EEG rejection limits.

Design: The video head impulse test (vHIT) was used to measure the eye movement response to small unpredictable passive head turns at intervals after the attack. Study sample: Two patients diagnosed with acute right unilateral vestibular neuritis. Results: There was full restoration of horizontal canal function in one patient (A) as shown by the return of the slow phase eye velocity response to unpredictable head turns, while in the other patient (B) there was little or no recovery of horizontal canal function. Instead this second patient generated covert saccades during head turns. Conclusion: Despite the objective evidence of their very different recovery patterns, both patients reported, at the final test, being happy and feeling well recovered, even though in one of the patients there was clear absence of horizontal canal function. The results indicate covert saccades seem a successful way of compensating for loss of horizontal canal function after unilateral vestibular neuritis. Factors other than recovery of the slow phase eye velocity are significant for patient recovery. C1 [Manzari, L.] MSA ENT Acad Ctr, Cassino, FR, Italy. [Burgess, A. M.; MacDougall, H.

Design: Cortical maturation, measured by P1 cortical auditory evoked potential (CAEP) latency, was regressed against scores on the infant toddler meaningful auditory integration scale (IT-MAIS). Implantation age was also considered in relation to CAEP findings. Study sample: Cross-sectional and longitudinal samples of 24 and 11 children, respectively, with ANSD fitted with CIs. Results: P1 CAEP responses were present in all children after implantation, though previous findings suggest that only 50-75% of ANSD children with hearing aids show CAEP responses. P1 CAEP latency was significantly correlated with participants' IT-MAIS scores. Furthermore, more children implanted before age two years showed normal P1 latencies, while those implanted later mainly showed delayed latencies. Longitudinal analysis revealed that most children showed normal or improved cortical maturation after implantation. Conclusion: Cochlear implantation resulted in measureable cortical auditory development for all children with ANSD. Children fitted with CIs under age two years were more likely to show age-appropriate CAEP responses within six months after implantation, suggesting a possible sensitive period for cortical auditory development in ANSD. That CAEP responses were correlated with behavioral outcome highlights their clinical decision-making utility.

Design: In Experiment 1, 22 music pieces were initially selected and paired as a 'familiar music piece' and 'unfamiliar music piece' based on familiarities amongst the general public in the categories of classical music (6), Chinese folk music (8), and pop music (8). Following the selection criteria, one pair of music pieces from each music category was selected and used for the MQRT in Experiment 2. In Experiment 2, the MQRT was validated using these music pieces in the categories 'Pleasantness', 'Naturalness', 'Fullness', 'Roughness', and 'Sharpness'. Study sample: Seventy-two adult participants and 30 normal-hearing listeners were recruited in Experiments 1 and 2, respectively. Results: Significant differences between the familiar and unfamiliar music pieces were found in respect of pleasantness rating for folk and pop music pieces as well as in sharpness rating for pop music pieces. The comparison of music category effect on MQRT found significant differences in pleasantness, fullness, and sharpness ratings. Conclusion: The Chinese MQRT developed in the present study is an effective tool for assessing music quality.

The end-product of these tests is a graphical profile summarizing absolute threshold, frequency selectivity, and compression characteristics across a spectrum of frequencies (0.25-6 kHz). Design: A battery of three psychophysical hearing tests consisted of measures of absolute threshold, frequency selectivity, and compression. An automated, cued, single-interval, adaptive tracking procedure was employed. The tests results were collated and used to generate a readily visualized 'profile' for each listener. Study sample: Participants were 83 adults (57 impaired-hearing and 26 good-hearing, age 20-75 years). Results: Listeners tolerated the tests well. Single-ear profiles were obtained in an average of 74 minutes testing time (range 46-120 minutes). The variability of individual measurements was low. Substantial differences between normal and impaired listeners and also among the impaired listeners were observed. Qualitative differences in compression and frequency-selectivity were seen that could not be predicted by threshold measurements alone. Conclusions: The hearing profiles are informative with respect to supra-threshold hearing performance and the information is easily accessible through the graphical display. Further development is required for routine use in a clinical context. C1 [Lecluyse, Wendy] Univ Campus Suffolk, Sch Appl Social Sci, Ipswich IP4 1QJ, Suffolk, England.

TI Audiometric thresholds and portable digital audio player user listening habits SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiometry; MP3 player; self-reported hearing loss ID SENSORINEURAL HEARING-LOSS; PERSONAL MUSIC PLAYERS; SOUND PRESSURE LEVELS; MP3 PLAYER; NOISE EXPOSURE; SUBJECTIVE TINNITUS; OLD STUDENTS; YOUNG-ADULTS; CHILDREN; ADOLESCENTS AB Objective: To examine the relationship between portable digital audio player listening behaviours and (1) measured sound pressure levels, (2) audiometric measures, (3) self-reported hearing loss symptoms. Design: A questionnaire to evaluate listening behaviours, including self-reported hearing loss symptoms and listening duration/ volume settings. Multivariate regression analysis was used to determine the relationship between these variables, audiometric evaluation, calculated exposure levels, Lex(8hr), and measured sound pressure levels, Leq(32sec). Study sample : This study included 103 males and 134 female subjects aged 10 to 17 years. Results : Calculated Lex(8hr) and measured Leq(32sec) levels increased with age and self-reported usage time. Audiometric thresholds averaged over 4 and 8 kHz were higher when usage exceeded fi ve years as compared to less than one year. Higher measured sound pressure levels were associated with worse audiometric thresholds at (0.5, 1, 2 kHz, averaged) and 4 kHz. Self-reported hearing loss symptoms were reported by 33% to 50% of subjects. Conclusions: In this cohort sample, our results support a statistical association between hearing acuity and (1) Self-reported weekly usage in hours; (2) Tightness of fi t; (3) Years of usage; and (4) Measured sound pressure levels. Generalizing these results beyond the current sample would require additional research.

TI Prescription of hearing-aid output for tinnitus relief SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Tinnitus; treatment; hearing aids ID FREQUENCY-RESPONSE; PITCH; AMPLIFICATION; THERAPY; GAIN AB Objective: Tinnitus is a perceived sound that cannot be attributed to an external source. This study attempts to identify a prescription of amplification that is optimized as a first-fit setting for tinnitus relief. Design : Participants compared the effect of high frequency amplification on their tinnitus. Stimuli were 13 speech files with different amounts of high frequency amplification (three cut-off frequencies and four gain settings) to simulate the effects of a change in DSL(I/O) v5.0 prescription in the high frequencies. Study sample: Twenty-five participants with chronic tinnitus participated in the study. Results: A 6-dB reduction to prescribed gain at 2 kHz emerged as the most preferred output (26.47% participants) to interfere with participants' tinnitus. Overall, 70.58% of the participants' preferred a 3 to 6 dB reduction in output while 29.42% preferred a similar increase across all cut-off frequencies. A trend was observed in which the higher the tinnitus pitch the more similar the preferred output to DSL(I/O) v5.0. Conclusion: DSL(I/O) v5.0 appears to be a good starting point for prescription of hearing-aid output for tinnitus management. Long-term benefits of different prescriptions for tinnitus still need to be ascertained.

However, at least at high stimulation levels, strong interactions reduce response amplitudes. The present study investigates ASSR interaction at a moderate stimulus level. Design: Sinusoidal carriers modulated at rates near 40 Hz were used as probe. Unmodulated and modulated interferers were presented ipsi- or contralaterally. Study sample: Twenty normal-hearing subjects participated. Results: Unmodulated interferers did not significantly change ASSR amplitudes. Modulated interferers, presented ipsilaterally or contralaterally, both significantly reduced the ASSR SNR by 13% and 8%, respectively. Conclusions: To compensate for the average SNR reduction would require a 32% and 18% longer measurement time for ipsi- and contralateral interferers, respectively, far less than the doubling of measurement time for two single measurements, emphasizing the MASSR technique advantage. However, the largest reduction for a single subject was 22% for the amplitude and 28% for the SNR, almost completely undoing the benefit in measurement time in MASSR. The individually varying interaction effects even at 60 dB SPL clearly limits the advantage of using the MASSR for modulation rates near 40 Hz over corresponding single ASSR measurements, at least for two simultaneous carriers.

Design: Pre- and post-tests were administered to two groups of subjects following the use of an interactive CD-ROM for tele-educational training. Study sample: Two groups of subjects were used: Group I (GI) consisted of 43 CHWs who had previously participated in at least one training activity involving hearing health, and Group II (GII) were 47 CHWs who had received no prior training in hearing health. Results: CHWs retained a significant amount of training content. There was not significant correlation between the global post-training questionnaire score and performance on the simulation activity (GI: r = 0.11, p = 0.698 and GII: r = 0.29, p = 0.074), and the simulation activity performance was significantly better among GI CHWs (p = 0.05). Conclusion: The CHWs' training in infant hearing health using an interactive tele-educational tool was effective, as the CHW demonstrated significant short-term information retention and applied such data in hypothetical situations representative of their daily activities.

HRQOL was also compared to a normative population. The second aim was to compare perceived effort (PE) and disturbance after completing a task in office noise between the two study groups. Design: A Swedish version of the short form-36 (SF-36) and the hearing handicap inventory for adults (HHIA) was used to determine HRQOL and hearing handicap. The Borg-CR 10 scale was used to measure PE and disturbance. Study sample: Hearing impaired (n = 20) and normally hearing (n = 20) participants. The normative sample comprised of 597 matched respondents. Results: Hearing-impaired employees report relatively good HRQOL in relation to the normative population, but significantly lower physical functioning and higher PE than their normally-hearing peers in noise. Results from the HHIA showed mild self-perceived hearing handicap. Conclusions: The current results demonstrate that physical health status can be negatively affected even at a mild-moderate severity of HI, and that a higher PE is reported from this group when performing a task in noise, despite the regular use of hearing aids.

TI Development of a subjective loudness rating scale SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Loudness rating; subjective assessment of noise; noise exposure ID NOISE AB Objective: In an earlier study (Beach et al, 2012), detailed noise exposure measurements were obtained through individual dosimetry. In this further analysis of the data we ask the question " Can the effort required to converse in noise be used to estimate the experienced A-weighted noise level? " Design: The noise levels experienced during specific activities were obtained from the analysis of dosimetry results from personal noise exposure meters worn by study participants. The measured noise levels from particular events were compared to a subjectively judged 'loudness rating' reported by the person wearing the dosimeter during the measured event. Study sample: Volunteers (females = 20, males = 22) between 18 and 35 years (average age = 26.8) willing to wear dosimeters and keep a simple activity log. Results: The relation between the objectively measured and the subjectively judged levels was consistent for the group over a large number of events. Conclusions: The subjective loudness rating index was shown to be a convenient tool that can be utilized for the retrospective estimation of noise levels from individual activities.

TI Improving speech-in-noise recognition for children with hearing loss: Potential effects of language abilities, binaural summation, and head shadow SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech-in-noise recognition; children; hearing loss; spatial release from masking ID BILATERAL COCHLEAR IMPLANTS; SPATIAL RELEASE; YOUNG-CHILDREN; WORD RECOGNITION; PERCEPTION; INTELLIGIBILITY; ADULTS; MASKING; AGE; PERFORMANCE AB Objective: This study examined speech recognition in noise for children with hearing loss, compared it to recognition for children with normal hearing, and examined mechanisms that might explain variance in children's abilities to recognize speech in noise. Design: Word recognition was measured in two levels of noise, both when the speech and noise were co-located in front and when the noise came separately from one side. Four mechanisms were examined as factors possibly explaining variance: vocabulary knowledge, sensitivity to phonological structure, binaural summation, and head shadow. Study sample: Participants were 113 eight-year-old children. Forty-eight had normal hearing (NH) and 65 had hearing loss: 18 with hearing aids (HAs), 19 with one cochlear implant (CI), and 28 with two CIs. Results: Phonological sensitivity explained a significant amount of between-groups variance in speech-in-noise recognition. Little evidence of binaural summation was found. Head shadow was similar in magnitude for children with NH and with CIs, regardless of whether they wore one or two CIs. Children with HAs showed reduced head shadow effects. Conclusion: These outcomes suggest that in order to improve speech-in-noise recognition for children with hearing loss, intervention needs to be comprehensive, focusing on both language abilities and auditory mechanisms.

TI False air-bone gaps at 4 kHz in listeners with normal hearing and sensorineural hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiometry; automated audiometry; hearing; hearing test; air conduction; bone conduction; threshold; air-bone gap; artificial mastoid ID AMTAS(R) AUTOMATED-METHOD; CONDUCTION THRESHOLDS; ACOUSTIC RADIATION; VIBRATORS; CALIBRATION; VALIDATION; EAR AB Objective: This report presents data from four studies to examine standard bone-conduction reference equivalent threshold force levels (RETFL), especially at 4 kHz where anomalous air-bone gaps are common. Design: Data were mined from studies that obtained air-and bone-conduction thresholds from normal-hearing and sensorineural hearing loss (SNHL) participants, using commercial audiometers and standard audiometric transducers. Study sample: There were 249 normal-hearing and 188 SNHL participants. Results: (1) Normal-hearing participants had small air-bone gaps at 0.5, 1.0, and 2.0 kHz (-1.7 to 0.3 dB) and larger air-bone gaps at 4 kHz (10.6 dB). (2) SNHL participants had small air-bone gaps at 0.5, 1.0, and 2.0 kHz (-0.7 to 1.7 dB) and a larger air-bone gap at 4 kHz (14.1 dB). (3) The 4-kHz air-bone gap grew with air-conduction threshold from 10.1 dB when the air-conduction threshold was 5-10 dB HL to 21.1 dB when the air-conduction threshold was greater than 60 dB. (4) With the 4-kHz RETFL corrected by the average SNHL air-bone gap, the relationship between RETFL and frequency is linear with a slope of -12 dB per octave. Conclusions: The 4-kHz air-bone gaps for listeners with SNHL could be avoided by adjusting the 4-kHz RETFL by -14.1 dB.

Design: A previously developed functional model of auditory processing was used to simulate the complete loss of inner hair cells (IHC), dysfunction of outer hair cells (OHC), complete loss of IHCs in combination with OHC dysfunction, and IHC insensitivity. The model predictions were verified through comparison with experimental data. Study sample: This study compares PTC data of five normal-hearing listeners and six hearing-impaired listeners with model-simulated PTC data. Results: It was shown that OHC activity and IHC insensitivity may significantly alter the shift of PTC tips with increasing probe level. Conclusions: Model results suggest that OHC activity and IHC insensitivity can change the outcome of dead region diagnosis using PTCs. Supplementary to PTC dead region diagnostic information, model results may provide additional information regarding the edge frequency of a dead region and OHC function.

TNF-alpha signaling has been shown to be activated in NIHL and to control spiral modiolar artery vasoconstriction that regulates cochlear microcirculation. It was the aim of this experimental study to analyse the effects of the TNF-alpha inhibitor etanercept on cochlear microcirculation and hearing threshold shift in NIHL in vivo. Design: After assessment of normacusis using ABR, loud noise (106 dB SPL, 30 minutes) was applied on both ears in guinea pigs. Etanercept was administered systemically after loud noise exposure while control animals received a saline solution. In vivo fluorescence microscopy of strial capillaries was performed after surgical exposure of the cochlea for microcirculatory analysis. ABR measurements were derived from the contralateral ear. Study sample: Guinea pigs (n=6, per group). Results: Compared to controls, cochlear blood flow in strial capillary segments was significantly increased in etanercept-treated animals. Additionally, hearing threshold was preserved in animals receiving the TNF-alpha inhibitor in contrast to a significant threshold raising in controls. Conclusions: TNF-alpha inhibition using etanercept improves cochlear microcirculation and protects hearing levels after loud noise exposure and appears as a promising treatment strategy for human NIHL.

Design: Cochlear dead regions were diagnosed using the TEN-HL test. A frequency discrimination test utilizing an adaptive three-alternative forced choice method provided difference limens for reference frequencies 0.25 kHz and 0.5 kHz. Study sample: Among 105 subjects with bilateral high-frequency hearing loss, unilateral dead regions were found in 15 subjects. These, and an additional 15 matched control subjects without dead regions, were included in the study. Results: Ears with dead regions performed best at the frequency discrimination test. Ears with a contralateral dead region performed significantly better than ears without a contralateral dead region at 0.5 kHz, the reference frequency closest to the mean audiogram cut-off, while the opposite result was obtained at 0.25 kHz. Conclusions: Results may be seen as sign of a contralateral effect of unilateral dead regions on the discrimination of stimuli with frequencies well below the audiogram cut-off in adult subjects with bilateral high-frequency hearing loss.

Design: A 60-item version of the questionnaire was developed and completed by 223 participants who also provided information about their hearing health behaviors (help seeking, hearing-aid acquisition, and hearing-aid use). Study sample: Individuals aged between 22 and 90 years recruited from a primary care waiting area at a Veterans hospital. Seventy-six percent were male, 80% were Veterans. Results: A 26-item version of the HBQ with six scales was derived using factor analysis and reliability analyses. The scales measured: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, and cues to action. HBQ scores differed significantly between individuals with different hearing health behaviors. Logistic regression analyses resulted in robust models of hearing health behaviors that correctly classified between 59% and 100% of participant hearing health behaviors. Conclusions: The HBM appears to be an appropriate framework for examining hearing health behaviors, and the HBQ is a valuable tool for assessing hearing health beliefs and predicting hearing health behaviors.

However, delayed-onset hearing loss subsequent to newborn hearing screening remains a concern. This study aimed to investigate the prevalence of delayed-onset hearing loss in preschool children who previously passed newborn hearing screening in Hubei Province in mid-south China. Design: Preschool children were screened by transient evoked otoacoustic emission (TEOAE) for delayed-onset hearing loss. Children referred after the TEOAE screening were assessed audiologically. Study sample: Between March 2010 and September 2011, 28 546 preschool children (4.86 +/- 1.67 years old), who had passed newborn hearing screening were targeted for screening from four cities in Hubei Province, China. Results: During the study period, 540 children (1.89%) were referred for audiologic assessment and 22 (0.77/1000) of them had permanent delayed-onset hearing loss, including 8 (0.28/1000) with bilateral moderate hearing loss, 10 (0.35/1000) with mild bilateral hearing loss, 2 (0.07/1000) with unilateral moderate hearing loss, and 2 (0.07/1000) with unilateral mild hearing loss. Conclusions: Despite the success of newborn hearing screening, the provision of hearing screening in preschool remains essential for identifying delayed-onset hearing loss.

This study has the purpose of developing a speech test signal in Brazilian Portuguese that is electroacoustically similar to the international long-term average speech spectrum (ILTASS) for use in real ear verification systems. Design: A Brazilian Portuguese speech passage was recorded using standardized equipment and procedures for one female talker and compared to ISTS. The passage consisted of simple, declarative sentences making a total of 148 words. Study sample: The recordings of a Brazilian Portuguese passage were filtered to the ILTASS and compared to the International Speech Test Signal (ISTS). Aided recordings were made at three test levels, for three audiograms for the Brazilian Portuguese passage and the ISTS. Results: The unaided test signals were spectrally matched to within 0.5 dB. Aided evaluation revealed that the Brazilian Portuguese passage produced aided spectra that were within 1 dB on average, within about 2 dB per audiogram, and within about 3 dB per frequency for 95% of fittings. Conclusion: Results indicate that the Brazilian Portuguese passage developed in this study provides similar electroacoustic hearing-aid evaluations to those expected from the standard ISTS passage.

The objective of the present study was to investigate whether a similar effect can be obtained for persons with hearing impairment and whether such an effect is dependent on individual differences in working memory capacity. Design: A sentence-final word identification and recall (SWIR) test was conducted in two noise backgrounds with and without noise reduction as well as in quiet. Working memory capacity was measured using a reading span (RS) test. Study sample: Twenty-six experienced hearing-aid users with moderate to moderately severe sensorineural hearing loss. Results: Noise impaired recall performance. Competing speech disrupted memory performance more than speech-shaped noise. For late list items the disruptive effect of the competing speech background was virtually cancelled out by noise reduction for persons with high working memory capacity. Conclusions: Noise reduction can reduce the adverse effect of noise on memory for speech for persons with good working memory capacity. We argue that the mechanism behind this is faster word identification that enhances encoding into working memory.

TI The applicability of a speech-in-noise screening test in occupational hearing conservation SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech-in-noise; self-administered; screening; occupational hearing conservation; speech reception threshold; noise-induced hearing loss; prevention ID CONSTRUCTION WORKERS; RECEPTION THRESHOLD; RELIABILITY; PROTECTION; AUDIOMETRY; TELEPHONE; INTERNET; INDUSTRY AB Objective: Noise-induced hearing loss (NIHL) is the most reported occupational health disease in the Netherlands. The internet-based speech-in-noise test Earcheck (Albrecht et al, 2005; Leensen et al, 2011b) is designed to detect beginning NIHL and can be a valuable tool in occupational hearing health surveillance. The aim of this study is to investigate the validity of Earcheck compared to regular screening audiometry. Design: Subjects performed online Earcheck tests at home. The results are compared to a pure-tone screening audiogram obtained during regular occupational health examination. A subgroup performed the measurements twice to assess test-retest reliability. Study sample: Two hundred and forty-nine male construction employees who recently had a periodic occupational health examination participated. Results: An average learning effect of -1.6 dB was found, that reduced with increasing test number. The test-retest variability was 1.6 dB. Sensitivity to detect beginning NIHL was 68%, with a specificity of 71%. Conclusions: Although sensitivity and specificity values are only moderate, the broad internet application still promises a valuable addition to current practice. The relatively high learning effect indicates that more reliable results can be obtained after a longer test session. When this is put into practice some improvement in sensitivity and specificity may be expected as well. C1 [Leensen, Monique C.

Design: Sequencing of the coding region, basal promoter, exon 1, and donor splice site of the GJB2 gene; screening for the presence of the two common GJB6 deletions. Study sample: A cohort of 264 Portuguese NSSHL patients. Results: At least one out of 21 different GJB2 variants was identified in 80 (30.2%) of the 264 patients analysed. Two mutant alleles were found in 53 (20%) of these probands, of which 83% (44/53) harboured at least one c. 35delG allele. Twenty-seven (10.2%) of the probands harboured only one mutant allele. Subsequent analysis revealed that the GJB6 deletion del(GJB6-D13S1854) was present in at least 7.4% (2/27) of the patients carrying only one mutant GJB2 allele. Overall, one in five (55/264) of the patients were diagnosed as having DFNB1-related NSSHL, of which the vast majority (53/55) harboured only GJB2 mutations. Conclusions: This study provides clear demonstration that mutations in the GJB2 gene are an important cause of NSSHL in Portugal, thus representing a valuable indicator as regards therapeutical and rehabilitation options, as well as genetic counseling of these patients and their families.

TI Placebo effects in hearing-aid trials are reliable SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Placebo effect; reliability; hearing-aid trial ID PAIN; EXPECTATIONS; ANALGESIA AB Objective: A recent study suggested that placebo effects are a source of bias in non-blinded hearing-aid trials. Given the potential impact of this finding on the interpretation of non-blinded trials and design of future research trials, the objective of the present study was to investigate the reliability of this effect. Design: Using the same procedure as an earlier study, participants were told that they were taking part in a trial of new hearing-aid technology. Participants compared two devices that were acoustically identical, except one was described as "new" and the other as "conventional". Participants completed a speech-in-noise test, sound quality ratings, and rated overall personal preference for both hearing aids. Study sample: Sixteen adult hearing-aid users. Results: Participants had significantly better mean speech-in-noise performance (70.9% versus 66.8%, Z = 2.30, p = 0.02, effect size Pearson's r = 0.15) and sound quality ratings for the "new" hearing aid (8.1 versus 7.4, Z = -2.99, p = 0.003, r = 0.28). A significant proportion of participants (75%) expressed an overall preference for the "new" hearing aid (p = 0.001, effect size. phi(c) = 0.66). Conclusion: Placebo effects reliably impact on hearing-aid trials. In order to control for placebo effects, double-blind methodology is optimal. However, when double-blinding is not possible other strategies may be appropriate.

We translated and validated a Chinese version of SADL (CSADL). Design: The SADL was translated from English to Mandarin Chinese by two bilingual physicians. The CSADL was administered to hearing-aid users and tested for reliability and validity. Study sample: There were 155 hearing-aid users who completed the CSADL prospectively, and 39 subjects were retested after 4 to 6 weeks for test-retest reliability. Results: The CSADL had good internal consistency (Cronbach alpha = 0.63 to 0.92), within survey reliability (r = 0.54 to 0.69; P <= .05), and test-retest reliability (r = 0.93 to 0.98; P <= .05). The CSADL dimensions correlated well with worse-ear speech discrimination score (P <= .05). The CSADL global score significantly correlated with the general health (r = 0.236; P <= .05), vitality (r = 0.162; P <= .05), social functioning (r = 0.190; P <= .05), and mental health (r = 0.224; P <= .05) subscales of the Mandarin Chinese Taiwan version of the medical outcome 36-item short-form health survey. Conclusions: The CSADL is a valid and reliable questionnaire to evaluate satisfaction among Chinese hearing-aid users.

A new fitting methodology is presented that, at its simplest level, requires a single volume adjustment, and at its advanced level, provides access to 22-channel fitting. It is implemented on multiple platforms, including a mobile platform (Remote Assistant Fitting) and an accessible PC application (Nucleus Fitting Software). Additional tools for home care and surgical care are also described. Design: Two trials were conducted, comparing the fitting methodology with the existing Custom Sound T methodology, as fitted by the recipient and by an experienced cochlear implant audiologist. Study sample: Thirty-seven subjects participated in the trials. Results: No statistically significant differences were observed between the group mean scores, whether fitted by the recipient or by an experienced audiologist. The lower bounds of the 95% confidence intervals of the differences represented clinically insignificant differences. No statistically significant differences were found in the subjective program preferences of the subjects. Conclusions: Equivalent speech perception outcomes were demonstrated when compared to current best practice. As such, the new technology has the potential to expand the capacity of audiological care without compromising efficacy.

Design: Retrospective data collection. Study sample: Sixty-four consecutive patients with unilateral sudden deafness or severe sensorineural hearing loss and either high-resolution CT (HRCT) of the temporal bone (isotropic spatial resolution <= 0.8 mm; n = 18) or high resolution CISS MRI (isotropic spatial resolution <= 1 mm; n = 55) were included. Nine patients underwent both imaging modalities. A standardized reading regarding labyrinthine ossifications was performed by an experienced head and neck radiologist blinded to clinical symptoms. Results: Radiologic signs of cochlear ossification were present in 14 patients (12 CT and 2 MRI). Eight patients showed unilateral and six patients bilateral signs of cochlear ossification. In all except one of the unilateral cases, the deafened ear was affected. Conclusions: Signs of cochlear ossification were found in an unexpectedly high rate (14/64, 22%) of patients with acute deafness. The data suggest HRCT of the temporal bone to be more sensitive to detect labyrinthine ossification than MRI. HRCT of the temporal bone should therefore be considered in patients with impaired recovery of acute deafness to exclude cochlear ossification; if present, and, in cases of early signs, the patient should be evaluated further to facilitate early cochlear implantation before progression impedes electrode insertion, reflecting latest developments considering cochlea implants for single-sided deafness to be effective.

Study sample: The cohort of babies studied were all babies referred for hearing assessment from the universal newborn hearing screen in Sheffield, UK for the period January 2002 to September 2007, who were found to have a significant hearing impairment. Design: The results of hearing assessment following referral from the newborn hearing screen were collected together with those of follow-up tests carried out up to an age when behavioural testing had established ear-and frequency-specific thresholds at 0.5, 1, 2 and 4 kHz. Results: The standard deviation of the difference between the follow up and the tone pip ABR thresholds was 10.5 dB for the 4-kHz tone pip, 16.8 dB for the 1-kHz tone pip, and ranged between 21.7 and 24.7 dB for click ABR. Conclusions: The results of the study show that tone pip ABR following referral from newborn hearing screening has a similar accuracy to that reported in older subjects, and is a much better predictor compared to click ABR.

Both sinusoidal amplitude modulated tones and tone pip stimuli were investigated. Design: Modulation/stimulus rates were 70, 80, and 90 Hz and the peak to peak stimulus levels were matched for the two different types of stimuli, at 90.5 dBSPLppe. Study sample: The study was carried out on fourteen normallyhearing adults (9 males and 5 females) Results: Overall the ASSR amplitude to the two types of stimuli was similar. In general there was an increasing response amplitude between rates of 70 and 90 Hz; The relationship between the amplitude of the response and the modulation/stimulus rate varied considerably between subjects. Conclusions: Optimum stimulus rates based on group data may not give the best rate in a significant proportion of subjects. Currently tone pip ABR is the primary method used in assessing hearing in babies. Finding a way of avoiding suboptimal stimulus rates for '80-Hz' ASSR in babies will improve the likelihood of ASSR being seen as an alternative.

TI Healthy diets, healthy hearing: National Health and Nutrition Examination Survey, 1999-2002 SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Diet; nutrition; healthy eating index; hearing loss ID ORAL MAGNESIUM INTAKE; OLDER-ADULTS; AUDITORY FUNCTION; ANALGESIC USE; EATING INDEX; RISK-FACTORS; BEAVER-DAM; US ADULTS; IMPAIRMENT; PREVALENCE AB Objective: A significant relationship between dietary nutrient intake and susceptibility to acquired hearing loss is emerging. Variability in the outcomes across studies is likely related to differences in the specific metrics used to quantify nutrient intake and hearing status. Most studies have used single nutrient analysis. Although this analysis is valuable, interactions between nutrients are increasingly recognized and could modify modeling of single nutrient effects. Therefore, we examined the potential relationship between diet and hearing using a metric of overall dietary quality. Design: This cross-sectional analysis was based on healthy eating index data and audiological thresholds. Study sample: Data for adults between the ages of 20 to 69 years of age were drawn from the National Health and Nutrition Examination Survey, 1999-2002. Results: Controlling for age, race/ethnicity, sex, education, diabetes, and noise exposure, we found a significant negative relationship (Wald F = 6.54, df = 4, 29; p <= 0.05) between dietary quality and thresholds at higher frequencies, where higher dietary quality was associated with lower hearing thresholds. There was no statistically significant relationship between dietary quality and threshold sensitivity at lower frequencies. Conclusions: The current findings support an association between healthier eating and better high frequency thresholds in adults. C1 [Spankovich, C.; Le Prell, C.

Previous assessments of reliability tested children with normal hearing or mild hearing impairment, and most studies used a version of the test without a masking sound. We assessed test-retest reliability for children with hearing impairment using maskers of broadband noise and two-talker babble. Design: Stimuli were presented from a loudspeaker. The signal-to-noise ratio (SNR) was varied adaptively to estimate the speech-reception threshold (SRT) corresponding to 70.7% correct performance. Participants completed each masked condition twice. Study sample: Fifty-five children with permanent hearing impairment participated, aged 3.0 to 6.3 years. Thirty-four children used acoustic hearing aids; 21 children used cochlear implants. Results: For the noise masker, the within-subject standard deviation of SRTs was 2.4 dB, and the correlation between first and second SRT was +0.73. For the babble masker, corresponding values were 2.7 dB and +0.60. Reliability was similar for children with hearing aids and children with cochlear implants. Conclusions: The results can inform the interpretation of scores from individual children. If a child completes a condition twice in different listening situations (e. g. aided and unaided), a difference between scores >= 7.5 dB would be statistically significant (p <.05).

Design: Correlational study. Study sample: Forty South African and 40 Chinese adults with a hearing loss and their partners. The participant group included 42 females and 38 males ranging in age from 32 to 92 years. Results: Ninety-five percent of South African and 60% of Chinese participants completed the assembly task, either on their own or with assistance from their partners. Better health literacy, younger age, and a more prestigious occupation were significantly associated with independent task completion for the South African and Chinese participants. Task accuracy was significantly linked to higher levels of cognitive function among South African participants, while a paucity of valid data prevented an analysis of accuracy from being conducted with the Chinese data. Conclusion: Individuals of diverse backgrounds can manage the self-fitting hearing-aid assembly task as long as health literacy levels and cultural differences are considered.

Design: Retrospective analysis. Study sample: 2 307 880 children born 01/04/06-30/09/09 in England. Results: Overall the prevalence for all PCHI in children with risk factors who pass newborn hearing screening is 1.49/1000. The risk factors with the highest prevalence are (1) Syndrome (other than Down's) associated with a hearing loss; (2) NICU with refer in both ears at OAE and pass in both ears at AABR; (3) Craniofacial anomaly; (4) Down's syndrome; (5) Congenital infection. Conclusion: Targeted surveillance for children who pass the screen and have the risk factors 1-5 listed above will be retained within the English NHSP; targeted surveillance for children who pass the screen and have other risk factors is not effective and has been discontinued.

Unilateral cochlear implantation has become an accepted treatment for ANSD but treatment options for the contralateral ear remain controversial. We report spatial hearing measures in a child with ANSD before and after receiving a second cochlear implant (CI). Study sample : An 11-year-7-month old boy with ANSD and expressive and receptive language delay received a second CI eight years after his first implant. Design: The SLA and SRM were measured four months before sequential bilateral CIs (with the contralateral ear plugged and unplugged), and after nine months using both CIs. Results: Testing done before the second CI, with the first CI alone, suggested that residual hearing in the contralateral ear contributed to sound localization accuracy, but not word recognition in quiet or noise. Nine-months after receiving a second CI, SLA improved by 12.76 degrees and SRM increased to 3.8-4.2 dB relative to pre-operative performance. Results were compared to published outcomes for children with bilateral CIs. Conclusions: The addition of a second CI in this child with ANSD improved spatial hearing.

TI A short form of the Speech, Spatial and Qualities of Hearing scale suitable for clinical use: The SSQ12 SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech; spatial and qualities of hearing scale; short version; clinical use; SSQ ID COCHLEAR; PERFORMANCE; ADULTS; AID AB Objective: To develop and evaluate a 12-item version of the Speech, Spatial and Qualities of Hearing scale for use in clinical research and rehabilitation settings, and provide a formula for converting scores between the full (SSQ49) and abbreviated (SSQ12) versions. Design: Items were selected independently at the three centres (Eriksholm Research Centre, MRC Institute of Hearing Research, University of New England) to be representative of the complete scale. A consensus was achieved after discussion. Study sample: The data set (n = 1220) used for a factor analysis (Akeroyd et al, submitted) was re-analysed to compare original SSQ scores (SSQ49) with scores on the short version (SSQ12). Results: A scatter-plot of SSQ12 scores against SSQ49 scores showed that SSQ12 score was about 0.6 of a scale point lower than the SSQ49 (0-10 scale) in the re-analysis of the Akeroyd et al data. SSQ12 scores lay on a slightly steeper slope than scores on the SSQ49. Conclusions: The SSQ12 provides similar results to SSQ49 in a large clinical research sample. The slightly lower average SSQ12 score and the slightly steeper slope reflect the composition of this short form relative to the SSQ49.

TI Real-ear output measures of ear level fluency devices SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Instrumentation; assistive technology; hearing conservation; noise ID ALTERED AUDITORY-FEEDBACK; FOLLOW-UP; SPEECH; STUTTER; PEOPLE; IMPACT AB Objective: The purpose of this study was to measure real-ear aided and saturated responses of SpeechEasy (TM) devices and compare responses while devices delivered altered auditory feedback (AAF) and non-altered feedback (NAF). Design: A repeated measures quasi-experimental design was employed. Study sample: Ten people fitted with completely-in-the-canal or open fit behind-the-ear devices participated. Probe microphone measures were obtained with speech, and 17 chirp stimuli presented at 75 dB and 85 dB SPL, respectively. Measurements were compared with devices delivering AAF (i.e. delayed and frequency shifted) versus NAF. Results: Maximum outputs were approximately 100-105 dB SPL in the 2000-4000 Hz range. Statistically significant differences in device SPL output as a function of device setting (AAF vs. NAF) were found for seven chirp stimuli (p <.05) when levels were sampled at points that were not temporally aligned with the output chirps but not for speech stimulus (p =.17). Device output varied across individuals and with open fit devices dominated by ear canal resonance effects. Conclusions : Real-ear aided responses were equivalent with speech input when devices delivered AAF and NAF. Real-ear saturated responses were not, however, comparable between AAF and NAF settings and may be underestimated if AAF delay is not accounted for.

Design: Tests were performed with tone pips and NB CE-Chirps at 4 kHz or 1 kHz. The response amplitude, response quality (Fmp), and residual noise were compared for both stimuli. Study sample: Thirty babies (42 ears) who passed our ABR discharge criterion at 4 kHz following referral from their newborn hearing screen. Results: Overall, NB CE-Chirp responses were 64% larger than the tone pip responses, closer to those evoked by clicks. Fmp was significantly higher for NB CE-Chirps. Conclusion: It is anticipated that there could be significant reductions in test time for the same signal to noise ratio by using NB CE-Chirps when testing newborns. This effect may vary in practice and is likely to be most beneficial for babies with low amplitude ABR responses. We propose that the ABR nHL threshold to eHL correction for NB CE-Chirps should be approximately 5 dB less than the corrections for tone pips at 4 and 1 kHz.

TI A cochlear implant user with exceptional musical hearing ability SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Pitch direction discrimination; melody recognition; timbre recognition; absolute pitch; relative pitch; consonance rating; cochlear implant; music perception ID CLINICAL-ASSESSMENT; SPEECH RECEPTION; ELECTRIC HEARING; RELATIVE PITCH; PERCEPTION; RECIPIENTS; RECOGNITION; LISTENERS; CONSONANCE; APPRAISAL AB Although the perception of music is generally poor in cochlear implant users, there are a few excellent performers. Objective: The aim of this study was the assessment of different aspects of music perception in one exceptional cochlear implant user. Design: The assessments included pitch direction discrimination, melody and timbre recognition, relative and absolute pitch judgment, and consonance rating of musical notes presented through the sound processor(s). Study sample: An adult cochlear implant user with musical background who lost her hearing postlingually, and five normally-hearing listeners with musical training participated in the study. Results: The CI user discriminated pitch direction for sounds differing by one semitone and recognized melody with nearly 100% accuracy. Her results in timbre recognition were better than average published data for cochlear implant users. Her consonance rating, and relative and absolute pitch perception were comparable to normally-hearing listeners with musical training. Conclusion: The results in this study showed that excellent performance is possible on musical perception tasks including pitch perception using present day cochlear implant technologies. Factors that may explain this user's exceptional performance are short duration of deafness, pre- and post-deafness musical training, and perfect pitch abilities before the onset of deafness.

It includes measures of loudness perception, listening effort, speech perception, spectral and temporal resolution, spatial hearing, self-reported disability and handicap, and cognition. Clinical applicability and comparability across different centres are investigated. Design: Headphone tests were conducted in five centres divided over four countries. Effects of test-retest, ear, and centre were investigated. Results for normally-hearing (NH) and hearing-impaired (HI) listeners are presented. Study sample: Thirty NH listeners aged 19-39 years, and 72 HI listeners aged 22-91 years with a broad range of hearing losses were included. Results: Test-retest reliability was generally good and there were very few right/left ear effects. Results of all tests were comparable across centres for NH listeners after baseline correction to account for necessary differences between test materials. For HI listeners, results were comparable across centres for the language-independent tests. Conclusions: The auditory profile forms a clinical test battery that is applicable in four different languages. Even after baseline correction, differences between test materials have to be taken into account when interpreting results of language-dependent tests in HI listeners. C1 [van Esch, Thamar E.

Design : This is a crossover four period trial. Study sample: Sixteen school-aged children with moderately severe to profound hearing losses participated in the study. The children were fitted with Phonak Naida V SP hearing aids according to the two prescriptive procedures. Results : The results showed that children performed significantly better with DSL v5 than with NAL-NL1 prescription for sentence perception in quiet. The paired-comparison judgments of speech intelligibility showed seven children significantly preferred the DSL v5 prescription while two children preferred the NAL-NL1 prescription. The average scores on functional and ratings by parents and teachers performance of children in real life were significantly better for the DSL v5 prescription. At the end of all trials, nine children preferred the DSL v5 prescription, four preferred the NAL-NL1 prescription, and two had no preference. Conclusions : Hearing aids fitted based on the DSL v5 procedure would seem to be more appropriate than the NAL-NL1 procedure for children with moderately severe to profound sensorineural hearing loss, at least in quiet listening environments.

Design: (1) Repeated measures in normal ears with experimentally-induced negative MEP; (2) Retrospective analysis of clinical data from ears with negative MEP. Study sample: Experimental data: 57 adult ears. Clinical data: 200 adult ears. Results: Mean peak Y-tm significantly increased (similar to 0.10 mmhos) under negative MEPs (> -190 daPa). TW increased, up to similar to 50 daPa, for MEP < -130 daPa. V-ea decreased when MEP < -190 daPa. With increasing negative MEP, peak Y-tm and tympanogram gradient tended to decrease. The within-subject variation of all measures and difference between normal and negative MEP were small. Conclusions: The tympanometry procedure increases peak Y-tm in ears with low to moderate negative MEP, and decreases gradient and V-ea with high negative MEP. This is referred to as hypercorrection of the admittance and should be accounted for in clinical norms. Results imply that tympanogram asymmetry is due to divergent effects of air pressure on the middle ear. The variability of tympanometry does not increase and reliability not decrease under negative MEP.

Design: Prospective study. Test-retest reliability was determined by assessing adults with AMTAS air-and bone-conduction audiometry. Accuracy was determined by comparing AMTAS and manual audiometry conducted on adults. AMTAS testing was conducted in a quiet room and manual audiometry in a sound booth. Study sample: Ten participants for test-retest reliability tests and 44 participants to determine accuracy were included. Participants had varying degrees of hearing loss. Results: For test-retest reliability the overall difference in air-conduction hearing thresholds (n = 119) was 0.5 dB. The spread of differences (standard deviation of absolute differences) was 4.9 dB. For bone-conduction thresholds (n = 99) the overall difference was -0.2 dB, and the spread of differences 4.5 dB. For accuracy the overall difference in air-conduction hearing thresholds (n = 509) between the two techniques was 0.1 dB. The spread of differences was 6.4 dB. For bone-conduction thresholds (n = 295) the overall difference was 0 dB, and the spread of differences 7.7 dB. Conclusions: Variations between air-and bone-conduction audiometry for automated and manual audiometry were within normally accepted limits for audiometry. However, AMTAS thresholds were elevated but not significantly different compared to other contemporary studies that included an automated audiometer.

Design: Cortical potentials were recorded for consonant-vowel syllable and tonal complex stimuli with varying pre-transition durations. Study sample: Ten individuals (three male and seven female) in the age range from 18 to 26 years, with normal hearing sensitivity, participated in the study. Results: The results revealed that a minimum pre-transition duration of 100 ms for tonal stimulus (with spectral change) and 80 ms for consonant-vowel syllable is necessary in order to elicit ACC. The latency of N1(1) and P2(1), which is the response for change within the ongoing stimulus, increased with increase in pre-transition duration. The amplitude of the evoked responses did not show any significant change. Conclusions: It was found that minimum pre-transition duration required in eliciting ACC for speech and non-speech stimulus is not same. The speech stimulus required lesser duration of pre-transition than non-speech stimulus. Further studies regarding the acoustic aspects of sound on CAEP in isolation are warranted. C1 [Ganapathy, M.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Aging; hearing aid ID BLUE MOUNTAINS HEARING; OLDER-ADULTS; IMPAIRMENT; PREVALENCE; USERS; DETERMINANTS; DISABILITIES; DEVICES; AGE AB Objective: Age-related hearing loss is an increasingly important public health problem affecting approximately 40% of 55-74 year olds. The primary clinical management intervention for people with hearing loss is hearing aids, however, the majority (80%) of adults aged 55-74 years who would benefit from a hearing aid, do not use them. Furthermore, many people given a hearing aid do not wear it. The aim was to collate the available evidence as to the potential reasons for non-use of hearing aids among people who have been fitted with at least one. Design: Data were gathered via the use of a scoping study. Study sample: A comprehensive search strategy identified 10 articles reporting reasons for non-use of hearing aids. Results: A number of reasons were given, including hearing aid value, fit and comfort and maintenance of the hearing aid, attitude, device factors, financial reasons, psychosocial/situational factors, healthcare professionals attitudes, ear problems, and appearance. Conclusions: The most important issues were around hearing aid value, i.e. the hearing aid not providing enough benefit, and comfort related to wearing the hearing aid. Identifying factors that affect hearing aid usage are necessary for devising appropriate rehabilitation strategies to ensure greater use of hearing aids.

Design: Speech in quiet and in noise were compared to preoperative data attained with conventional hearing aids so that each subject served as his or her own control in a single test protocol. Study sample: Eighteen adults implanted monaurally with the VSB in the poorer hearing ear. Experience with the VSB ranged from nine to 25 months. Results: Sixteen of the 18 subjects were successful VSB users, wearing their device all waking hours. There was no significant deterioration in the averaged bone conduction results preoperatively versus post-operatively (p > 0.05). Speech recognition in quiet results were not significantly different to performance attained whilst wearing hearing aids (p > 0.05). Speech recognition in noise performance was substantially improved with use of the VSB in most test conditions. Conclusions: For the majority of the subjects, the VSB was an effective method of hearing restoration for their mixed and conductive hearing loss C1 [Marino, Roberta; Linton, Nicola; Eikelboom, Robert H.; Statham, Elle] Ear Sci Inst Australia, Subiaco, WA, Australia.

Study sample: Ninety-eight children received implants before 2.5 years, and 62 children received implants between 2.5 and 5 years of age. Design: Language was assessed using four subtests of the Comprehensive Assessment of Spoken Language (CASL). Standard scores were evaluated by contrasting age of implantation and follow-up test time. Results: Children implanted under 2.5 years of age achieved higher standard scores than children with older ages of implantation for expressive vocabulary, expressive syntax, and pragmatic judgments. However, in both groups, some children performed more than two standard deviations below the standardization group mean, while some scored at or well above the mean. Conclusions: Younger ages of implantation are associated with higher levels of performance, while later ages of implantation are associated with higher probabilities of continued language delays, particularly within subdomains of grammar and pragmatics. Longitudinal data from this cohort study demonstrate that after 6 years of implant experience, there is large variability in language outcomes associated with modifiers of rates of language learning that differ as children with implants age.

In spite of this, there is limited understanding of the underlying mechanisms. We hypothesized that individuals with hyperacusis would be prone to suffer from psychiatric disorders, related in particular to anxiety. Therefore, psychiatric morbidity and personality traits were investigated, along with different sociodemographic and clinical characteristics. Design: Patients were assessed with a clinical interview related to symptoms of hyperacusis, the Mini-international neuropsychiatric interview (MINI), and the Swedish Universities scales of Personality (SSP) to study psychiatric disorders and personality traits. Study sample: A group of 62 Swedish patients with hyperacusis between 18 and 61 years (mean 40.2, SD 12.2) was included. Results: Altogether 56% of the patients had at least one psychiatric disorder, and 47% had an anxiety disorder. Also, personality traits related to neuroticism were over-represented. A majority, 79%, suffered from comorbid tinnitus, and a similar proportion used measures to avoid noisy environments. Conclusions: The over-representation of anxiety disorders and anxiety-related personality traits in patients with hyperacusis suggests common or cooperating mechanisms. Cognitive behavioural treatment strategies, proven efficient in treating anxiety, may be indicated and are suggested for further studies.

Design: Word-recognition scores (WRSs) were obtained in quiet and in the presence of background competing continuous and interrupted noise at signal-to-noise ratios (SNRs) of -20, -10, 0, and 10 dB. Study sample: Two groups of 33 ML Persian and 36 BL Turkish-Persian volunteers participated. Results: WRSs significantly differed between ML and BL subjects at four sensation levels in the presence of continuous and interrupted noise. However, the difference in the release from masking between ML and BL subjects was not significant at the studied SNRs. Conclusions: BL Turkish-Persian listeners seem to show poorer performance when responding to Persian words in continuous and interrupted noise. However, bilingualism may not affect auditory temporal resolution ability. C1 [Omidvar, Shaghayegh; Tahaei, Ali Akbar] Univ Tehran Med Sci, Sch Rehabil, Dept Audiol, Tehran 1545913487, Iran.

Design: A cross-sectional e-mail survey using the demand-control-support questionnaire, a short version of the effort-reward imbalance (ERI) questionnaire, and descriptive data. Study sample: Five-hundred Swedish licensed audiologists. Results: Overall, the results indicate differences in psychosocial work environment pertaining to the practice types. These differences are small and the type explains few percent of the variability accounted in the measures of psychosocial work environment. Social support seems important for the psychosocial work environment and is considered a reward in itself. Using the demand-control model, 29% of the audiologists reported working in a high-stress psychosocial work environment. Using the ERI-ratio to estimate the imbalance between effort and reward it was shown that that 86% of the participants experienced an unfavorable work situation where the rewards do not correspond to the efforts made. Conclusions: The organizational framework has minor effect on self-reported psychosocial work environment for Swedish licensed audiologists. The percentage of unfavorable ERI-ratios seen in Swedish audiologists seems conspicuously high compared to other working populations in general, but also compared to other health service workers.

Design: The study used a sequential groups design. Twenty participants were asked to find and demonstrate understanding of 11 key points of information contained within two NHS leaflets, A and B (10 participants each), through individual structured-interviews. Participants' views of the leaflets were explored through a short semi-structured interview. Following analysis, a revised leaflet was developed and tested on a further 20 participants. Study sample: 40 participants (25F/15M, aged 46-72) with no experience of balance problems or balance assessment appointments. Results: Participants exhibited difficulties with finding and/or understanding 5/11 and 6/11 points of information within leaflets A and B, respectively. Five out of eleven points of the revised leaflet also posed problems. Ten out of eleven points were understood by >90% of participants testing the revised leaflet compared with 6/11 points for leaflets A and B. Conclusions: Some balance appointment PILs contain information which is difficult to find and/or understand for some readers. PILs should be evaluated prior to use using performance-based methods, since poor information provision may lead to increased patient anxiety and appointment non-attendance, cancellation, or postponement.

The impact of these designs on the reliability of real ear measurements (REMs) has not been reported. The purpose of this study was to obtain REM reliability data for instant fit coupling systems. Design: REM reliability data was obtained for four different instant-fit coupling systems and for standard size 13 tubing and custom earmolds. REMs were performed for all five coupling systems two times and by two examiners. Study sample: Ten normal-hearing individuals (20 ears) served as participants. Results: The REM test-retest reliability is high for the four instant fit coupling systems as well as for the custom earmolds. The REM inter-examiner reliability is high for three of the four instant fit coupling systems. Conclusions: Carrying out REMs with instant fit coupling systems appears to be fundamentally no different than performing REMs with conventional hearing aids. For either, care should be taken in probe tube placement in terms of insertion depth and maintaining the probe tube placement, and other best practices regarding test environment and test setup should be observed.

Little is understood about why only a small percentage of patients become severely affected. Catastrophic thinking has been suggested as one potentially relevant factor that might influence a patient's coping behavior, and thus tinnitus habituation. The current study investigates the concept of tinnitus catastrophizing and its relation with distress and medical utilization in recent onset tinnitus. Design: Participants were administered a survey assessing catastrophizing, tinnitus distress, medical utilization, coping, and mood disturbance. Regression analyses investigated the nature of tinnitus catastrophizing and its contributions to distress and health care utilization. Study sample: 278 subjects with tinnitus for less than six months were recruited from Ear-Nose-Throat units, through the internet, and newspaper articles. Results: Controlling for background variables, high subjective tinnitus loudness, low behavioral coping, and depressive symptoms were significantly associated with tinnitus catastrophizing. Furthermore, greater tinnitus catastrophizing was related to higher distress and more frequent medical visits. Conclusions: Tinnitus catastrophizing appears to be pivotal already at an early stage of tinnitus experience. Addressing catastrophizing by specific prevention and intervention programs might reduce the development of distress and medical utilization in the long term. Longitudinal studies are required to clarify cause-effect relations. C1 [Weise, Cornelia] Univ Marburg, Dept Psychol, Div Clin Psychol & Psychotherapy, D-35032 Marburg, Germany.

Goverts, S. Theo TI The effect of a carrier phrase on hearing aid amplification of single words in quiet SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech perception; hearing aids; speech audiometry; amplitude compression AB Objective: A common method to assess the functional benefit of hearing aids is by measuring the performance-intensity curve of single words in quiet with and without hearing aids. Currently, virtually all hearing aids use signal processing, which may have a marked effect on gain as a function of time. Thus, hearing-aid behavior may be different for a word presented in isolation compared to the same word preceded by a carrier phrase, which is a closer replication of natural conversation. The present research was conducted to assess this difference. Design: In a hearing-aid test box, speech materials were routed through hearing aids and the output was recorded with a 2cc coupler. Study sample: Seven different hearing aids were programmed according to the manufacturer's fitting rules, using a given hearing loss. Results: Depending on the hearing aid, and the hearing-aid setting, differences in the overall level of the hearing-aid processed words ranged from -1.5 to 3.5 dB. Differences were due to slow attack times in amplitude compression. Conclusions: Although differences were small for most hearing aids, the use of a carrier phrase should be considered in speech intelligibility tests to ensure that hearing-aid performance closer reflects that in real life.

Design: A retrospective study was performed; it included a review of medical records and follow-up 28-30 years after surgery, including audiometry, clinical examination, structured interview, and a validated questionnaire, IOI-HA. Study sample: Sixty-five patients, who had undergone stapedectomy at a tertiary referral center in 1977-79. Results: In 95% of the subjects there was a theoretical need for hearing-aid amplification at follow-up; 46% of the subjects had no hearing aids, while 26% had unilateral and 28% bilateral hearing aids. Hearing sensitivity in the best ear predicted hearing-aid uptake. Of the subjects with a hearing aid, 94% were everyday users and 54% were full-time users (>8 hours/day). The subjects reported a high level of satisfaction (mean 4.5) and benefit (mean 4.2), but also residual activity limitations (mean 3.1). Conclusions: The study shows that there is an unmet need for long-term hearing rehabilitation among patients previously undergoing surgery for otosclerosis. The patients who were using hearing aids were generally very satisfied with their hearing aids, but they still reported residual activity limitations.

Design: Prospective study. Study sample: Initially, 20 healthy volunteers aged 23-38 years underwent cVEMP tests in supine position using head elevation method by BCV tapping at the Fz and inion. On another day, the same subjects underwent cVEMP tests in seated position with head rotation method by BCV tapping at the Fz and inion. Another 20 healthy subjects aged 41-60 years undergoing cVEMP tests by BCV tapping at the inion were also included for comparison. Results: Tapping at the inion (100%) had significantly higher response rate of cVEMPs than tapping at Fz (65-70%), regardless of whether the head was elevated or rotated. Except for mean latencies of p13 and n23, the mean p13-n23 amplitude, corrected amplitude, and asymmetry ratio did not differ significantly between the elevation and rotation methods when cVEMPs were elicited by inion tapping; both methods showed excellent test-retest reliability. Conclusions: The BCV at the inion is the optimal method for eliciting BCV cVEMPs. These responses can be recorded using either the seated/head rotation method or supine/head elevation method.

This study investigated young people's participation in high-noise leisure activities and the relationship between their leisure noise exposure, symptoms of hearing damage, and perception of risk. Design: Participants completed an online survey relating to participation in selected high-noise leisure activities, symptoms of hearing damage, and beliefs about the risk posed by these activities. Study sample: One thousand 18- to 35-year-old Australian adults completed the survey. Results: Annual noise exposure from the five leisure activities ranged from 0-6.77 times the acceptable noise exposure, with nightclubs posing the greatest risk. Those who attended one noisy activity were more likely to attend others, in particular nightclubs, pubs, and live music events. Noise exposure was correlated with early warning signs of hearing damage and perceived risk of damage. Conclusions: Active young adults who engage in noisy activities are showing early signs of hearing damage. Furthermore, they perceive the risk associated with their activities. The challenge for researchers and hearing health practitioners is to convert self-perceived risk into positive hearing health behaviours for long-term hearing health.

Design: An online survey was used to investigate participants' own hearing health, their engagement with noise reduction behaviour, and their beliefs about hearing health and the risk posed by leisure activities. Study sample: Results are presented for 1000 Australian young adults (18 - 35 years). Results: Most participants reported current good hearing health, although over a fifth showed possible early warning signs of damage. Approximately half of participants took steps to reduce their noise exposure. However, preventative action was not related to hearing loss symptomology, or perceived personal risk of noise-related damage. Participants' engagement with hearing health was related to beliefs about the risk posed by leisure noise, hearing health awareness, and the importance of hearing. Conclusions: There is a need to further educate young people about the risks posed to hearing by leisure activity participation and factors that may assist improve hearing health. It is important that hearing health messages move past the traditional emphasis on knowledge, and move towards the use of more personalized motivators of noise reduction behaviour.

Design: A randomized trial of the four interventions with a non-intervention comparison group. Questionnaires were completed prior to, immediately after, and three months after each intervention. Study: Interventions included: (1) A classroom presentation by older-peer educators, (2) A classroom presentation by health professionals, (3). Exploration of a museum exhibition, and (4). Exploration of an internet-based virtual museum. A comparison group received no intervention. Study sample: Fifty-three fourth grade classrooms (1120 students) participated in the study. Results: All interventions produced significant improvements but the number of improvements decreased over time. In terms of effectiveness, the classroom programs were more effective than the internet-based virtual exhibit, which was more effective than the visit to the museum exhibition. Self-reported exposures indicated that as many as 94.5% of participants were at risk for NIHL. Conclusions: Interpersonal, interactive educational interventions such as the classroom program are more effective and have longer impact than self-directed learning experiences for NIHL and tinnitus prevention, however each may have an important role in promoting hearing health in elementary school students.

TI Impact of daily noise exposure monitoring on occupational noise exposures in manufacturing workers SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Exposure monitoring; noise; intervention study ID HEARING PROTECTION DEVICES; ATTENUATION AB Objective: Despite the use of hearing protection devices (HPDs), noise induced hearing loss (NIHL) remains one of the most prevalent occupational conditions. A new technology allows for daily monitoring of noise exposures under HPDs. We report on an intervention employing the voluntary use of this technology in a worksite setting. Design: Volunteers were fitted with a device allowing them to monitor noise exposure under their hearing protection on a daily basis. The trends in noise exposures for individuals who completed at least six months of the intervention were analysed. Study sample: Recruitment occurred at three manufacturing facilities, with 127 workers enrolling and 66 workers actively using the device during their work shifts. Results: Among volunteers downloading regularly, the percentage of daily exposures in excess of the OSHA action level (85 dBA) decreased from 14% to 8%, while the percentage of daily exposures in excess of 90 dBA decreased from 4% to less than 2%. Conclusion : Initial results from this longitudinal study indicate that volunteers find daily noise exposure monitoring to be feasible, and that workers who monitor daily are able to reduce exposures. The results of subject adherence shed light on the challenges and possibilities of worksite interventions for health and safety.

Design: Acoustic comparison of impulses generated from typical .22 and .32 caliber starter pistols firing blanks were made to impulses generated from comparable firearms firing both blanks and live rounds. Acoustic characteristics are described in terms of directionality and distance from the shooter in a simulated outdoor running track. Metrics include peak sound pressure levels (SPL), A-weighted equivalent 8-hour level (L-eqA8), and maximum permissible number of individual shots, or maximum permissible exposures (MPE) for the unprotected ear. Results: Starter pistols produce peak SPLs above 140 dB. The numbers of MPEs are as few as five for the .22-caliber starter pistol, and somewhat higher (<= 25) for the .32-caliber pistol. Conclusion: The impulsive sounds produced by starter pistols correspond to MPE numbers that are unacceptably small for unprotected officials and others in the immediate vicinity of the shooter. At the distances included in this study, the risk to athletes appears to be low (when referencing exposure criteria for adults), but the sound associated with the starter pistol will contribute to the athlete's overall noise exposure.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing conservation; noise; behavioral measures; psychoacoustics/hearing science ID COLLEGE-STUDENTS; LISTENING HABITS; HEARING; NOISE AB Objective: This study was designed to evaluate the usage patterns of portable listening device (PLD) listeners, and the relationships between self-report measures and long-term dosimetry measures of listening habits. Design: This study used a descriptive correlational design. Study sample: Participants (N = 52) were 18-29 year old men and women who completed surveys. A randomly assigned subset (N = 24) of participants had their listening monitored by dosimetry for one week. Results: Median weekly noise doses reported and measured through dosimetry were low (9-93%), but 14.3% of participants reported exceeding a 100% noise dose weekly. When measured by dosimetry, 16.7% of participants exceeded a 100% noise dose weekly. The self-report question that best predicted the dosimetry-measured dose asked participants to report listening duration and usual listening level on a visual-analog scale. Conclusions: This study reports a novel dosimetry system that can provide accurate measures of PLD use over time. When not feasible, though, the self-report question described could provide a useful research or clinical tool to estimate exposure from PLD use. Among the participants in this study, a small but substantial percentage of PLD users incurred exposure from PLD use alone that increases their risk of music-induced hearing loss. C1 [Portnuff, C. D.

Design: A within-subject repeated measures design was employed to compare air (250 to 8000 Hz) and bone (250 to 4000 Hz) conduction pure-tone thresholds, measured in retirement facilities, with thresholds measured in a sound-treated booth. Study sample: One hundred and forty-seven adults (average age 76 +/- 5.7 years) were evaluated. Pure-tone averages were >= 25 dB in 59%, mildly (>40 dB) elevated in 23%, and moderately (>55 dB) elevated in 6% of ears. Results: Air-conduction thresholds (n = 2259) corresponded within 0 to 5 dB in 95% of all comparisons between the two test environments. Bone-conduction thresholds (n = 1669) corresponded within 0 to 5 dB in 86% of comparisons. Average threshold differences (-0.6 to 1.1) and standard deviations (3.3 to 5.9) were within typical test-retest reliability limits. Thresholds recorded showed no statistically significant differences (paired samples t-test: p > 0.01) except at 8000 Hz in the left ear. Conclusion : Valid diagnostic pure-tone audiometry can be performed in a natural environment with recently developed technology, offering the possibility of access to diagnostic audiometry in communities where sound-treated booths are unavailable.

Design: A population-based cohort of 4202 adults was examined with air conduction pure-tone audiometry, transient OAE (TEOAE), and distortion product OAE (DPOAE). Participants completed 15 self-report items on hearing disability. Results: Correlation coefficients in the range of 0.3 to 0.5 were observed between OAE (TEOAE, and DPOAE) and self-reported hearing depending on age and sex. Pure-tone average hearing thresholds generally predicted self-reported hearing slightly better than did the OAE measures. Adding TEOAE and DPOAE as predictors in a multivariate model together with the scores from pure-tone audiometry did not predict self-reported hearing better than did pure-tone audiometry alone. The relationship between OAE and self-reported hearing was stronger in men than in women and became more manifest with age, a trend also stronger in men. Conclusions: OAEs were shown to be a valid measure of self-reported hearing disability of the general population but added no additional information to what pure-tone hearing thresholds had already captured.

TI The equivalence of acceptable noise level (ANL) with English, Mandarin, and non-semantic speech: A study across the US and Taiwan SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Acceptable noise level; English; Mandarin; international speech test signal ID COCHLEAR IMPLANT USERS; HEARING-AID USE; BACKGROUND-NOISE; LISTENERS; PERCEPTION; TALKERS; MASKING; BENEFIT AB Objective: Acceptable noise level (ANL) determines the maximum noise level that a listener is willing to accept while listening to speech. The objective of this study was to determine the equivalence of ANL measured using different speech stimuli for native speakers who lived in the U. S. and Taiwan. Design: ANLs were measured using English, Mandarin, and the international speech test signal (ISTS) at each site. The same babble noise was used across speech stimuli. The ANLs were considered equivalent if the difference was unlikely to be greater than 3 dB. Study sample: Thirty adults with normal hearing were recruited at each site. Results: For each site, the equivalence test suggested that the native-language and foreign-language ANLs were equivalent. Between the two sites, ANLs measured using the listener's native language were also equivalent. Although the ISTS ANL obtained within each site was equivalent to, and highly correlated to, the native-language ANL, the data were unable to confirm the equivalence of the ISTS ANLs obtained from the two sites. Conclusions: The results suggested the possibility of directly comparing ANL measures carried out in different countries using different languages. However, it remains unclear if the ISTS can serve as an international ANL stimulus. C1 [Ho, Hsu-Chueh; Hsiao, Shih-Hsuan] Buddhist Dalin Tzu Chi Gen Hosp, Dept Otolaryngol, Chiayi, Taiwan.

Design: A retrospective observational study initially, followed by a postal Glasgow health status inventory (GHSI) to establish the patients' functional outcomes. Study sample: A clinical database of 32 781 cases was interrogated from which 2199 cases of severe /profound hearing loss were identified. From these, an adult sample stratified in terms of age and gender of n = 302 was contacted. Results: An estimated 6.7% of the local clinical population and 0.7% of the general population were found to have hearing > 70 dB averaged over 0.5, 1, and 2 kHz. Most patients were fitted with bilateral hearing aids, using a non-linear prescription, and as a group they reported a high level of social support. Conclusions: This study has estimated the prevalence of severe and profound hearing loss as 6.7% of the clinical population, and 0.7% of the general population. This is consistent with previous work, although it probably underestimates the prevalence. Further work is indicated to strengthen the estimate.

Design: Clinical evaluations, sequence analysis of mitochondrial DNA (mtDNA) as well as two nuclear genes TRMU and MTO1 encoding mitochondrial proteins. Study sample: Two Chinese families with aminoglycoside-induced and NSHL. Results: Clinical evaluations revealed incomplete penetrance (28.6% vs. 40.0%) and variable phenotype of hearing losses between two families. When the effect of aminoglycosides was excluded, the penetrances were both 0%. Sequence analysis of mitochondrial genomes showed a homoplasmic 1494C>T mutation in the 12S rRNA gene (MT-RNR1) in all maternal relatives, as well as distinct sets of mtDNA polymorphism belonging to Eastern Asian haplogroups D4j and D5a2, respectively. However, none of these mtDNA variants was highly evolutionarily conserved and implicated to have functional significance. No mutations were identified in either TRMU or MTO1 gene. Conclusions: Mitochondrial 1494C>T mutation is the molecular basis responsible for the NSHL of two families, and the use of aminoglycoside antibiotics can worsen the hearing of the mutation carriers. Our results indicate the importance of a systematic screening for the mitochondrial 1494C>T mutation in Chinese subjects in the prevention of aminoglycoside-induced and non-syndromic hearing loss.

TI Refractory effects of the N1 event-related potential in experienced cochlear implant patients SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implant; EEG; hearing loss; auditory evoked potential (AEP); auditory refractory period ID INDEPENDENT COMPONENT ANALYSIS; AUDITORY-EVOKED POTENTIALS; CROSS-MODAL PLASTICITY; CORTICAL REORGANIZATION; HEARING-LOSS; USERS; CHILDREN; SPEECH; PERCEPTION; STIMULI AB Objective: To determine if cochlear implant (CI) patients exhibit a temporal processing deficit for auditory stimuli, by examining refractory effects of the N1 event-related potential (ERP) component. Design: CI patients and normally-hearing controls were tested in an auditory refractory period paradigm while ERP recordings were collected across the scalp. Participants were presented with brief 500-Hz tones that were separated by inter-stimulus intervals (ISIs) of 500, 1000, or 3000 ms. The amplitude of the N1 was examined as a function of ISI within each group. Study sample: Ten adult CI patients and 13 age-matched normally-hearing controls were tested. Patients had long-lasting severe or profound sensorineural hearing loss prior to implantation, and a minimum of two years experience with CI activation. Results: Unlike normally-hearing controls, CI users showed no refractory effect for tones at 500 ms ISIs compared to 1000 ms. However, similar to controls, recovery from refractoriness was observed in anterior locations at 3000 ms. Conclusion: The refractory period threshold, defined as the minimum ISI where different N1 amplitudes are elicited, is greater than 1000 ms in CI patients; at least double that of normally-hearing controls.

TI Gaps-in-noise (GIN (c)) test results in children with and without reading disabilities and phonological processing deficits SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory processing; auditory temporal resolution; dyslexia; gap detection ID DEVELOPMENTAL DYSLEXIA; DETECTION THRESHOLDS; CONTRAST SENSITIVITY; PRESCHOOL-CHILDREN; SPEECH-PERCEPTION; ABILITY; LITERACY; DISORDER; SKILLS; PERFORMANCE AB Objective: To determine if the gaps-in-noise (GIN (c)) test could differentiate children with dyslexia and significant phonological awareness deficits from a group of children with normal reading skills. Design: A prospective study of GIN test performance in two groups of children. Participants were administered routine audiological tests, a phonological processing test, and an auditory temporal resolution test (GIN test). Statistical testing was completed to determine if significant differences existed between groups on GIN test results and phonological processing measures, and to examine potential relationships between these test measures. Routine clinical analysis procedures examined the performance of the two groups from a clinical perspective. Study sample: Participants included 61 children between the ages of 8 years, 1 month and 9 years, 11 months, separated into two groups: children with dyslexia and significant phonological deficits (Group I); normal-reading peers with age-appropriate phonological skills (Group II). Results: Children in Group I showed longer gap detection (GD) thresholds and lower gap identification scores than did the children in Group II. Results of statistical and clinical testing revealed significant differences between the groups. Conclusion: An auditory temporal processing deficit is a factor to be considered in children presenting with dyslexia and phonological processing disorders.

Davis, Adrian Simpson, Sue Packer, Claire TI The future role of genetic screening to detect newborns at risk of childhood-onset hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Horizon scanning; genetic screening; genetic testing; hearing loss; innovation ID DEAFNESS; MUTATIONS; TECHNOLOGIES; IMPAIRMENT; MICROARRAY; GENOMICS; AGE AB Objective: To explore the future potential of genetic screening to detect newborns at risk of childhood-onset hearing loss. Design: An expert led discussion of current and future developments in genetic technology and the knowledge base of genetic hearing loss to determine the viability of genetic screening and the implications for screening policy. Results and Discussion: Despite increasing pressure to adopt genetic technologies, a major barrier for genetic screening in hearing loss is the uncertain clinical significance of the identified mutations and their interactions. Only when a reliable estimate of the future risk of hearing loss can be made at a reasonable cost, will genetic screening become viable. Given the speed of technological advancement this may be within the next 10 years. Decision-makers should start to consider how genetic screening could augment current screening programmes as well as the associated data processing and storage requirements. Conclusion: In the interim, we suggest that decision makers consider the benefits of (1) genetically testing all newborns and children with hearing loss, to determine aetiology and to increase knowledge of the genetic causes of hearing loss, and (2) consider screening pregnant women for the m. 1555A>G mutation to reduce the risk of aminoglycoside antibiotic-associated hearing loss.

Design: Patients and their parents underwent clinical and genetic evaluations. To identify genetic mutations, sequencing of SLC26A4 was carried out. Study sample: Two siblings and their parents. Results: Clinical evaluations showed that patient 1 suffered from bilateral postlingual progressive sensorineural hearing loss with enlarged vestibular aqueduct and slight diffuse multinodular goiter with euthyroid, and patient 2 suffered from bilateral prelingual progressive sensorineural hearing loss with enlarged vestibular aqueduct and no goiter with euthyroid. Furthermore, the sequence analysis of SLC26A4 indicated that either of the two siblings presented a compound heterozygote for the c.919A>G mutation in the splice site of intron 7 and for the c. 1548insC mutation in exon 14. Their mother was a heterozygous carrier of the splice site mutation in intron 7, and their father was a heterozygous carrier of the insertion mutation in exon 14. Conclusions : Mutation analysis identified a compound heterozygous mutation (c.919A>G/c. 1548insC) in SLC26A4 in two Chinese siblings with Pendred syndrome. Also, c. 1548insC was first reported in the Chinese population. Although the two siblings from the same family carried the same genotype, they presented different phenotypes.

Design: The auditory stimuli, presented through a loudspeaker, consisted of four carrier tones (500, 1000, 2000, and 4000 Hz), presented singly for behavioral testing but combined (multiple frequency technique), to estimate thresholds using the ASSR. Study sample: Twenty normal-hearing adults were examined. Results: The average differences between the physiological and behavioral thresholds were between 17 and 22 dB HL. The Spearman rank correlation between ASSR and behavioral thresholds was significant for all frequencies (p < 0.05). Significant differences were found in the ASSR amplitude among frequencies, and strong correlations between the ASSR amplitude and the stimulus level (p < 0.05). Conclusions: The ASSR in sound field testing was found to yield hearing threshold estimates deemed to be reasonably well correlated with behaviorally assessed thresholds.

Sirimanna, Tony TI Evolving concepts of developmental auditory processing disorder (APD): A British Society of Audiology APD Special Interest Group 'white paper' SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Behavioral measures; paediatric; speech perception; psychoacoustics/hearing science ID BRAIN-STEM; SPEECH; CHILDREN; RELIABILITY AB Children with listening difficulties, but normal audiometry, may be diagnosed with APD. The diagnosis is typically based on poor performance on tests of perception of both non-speech and speech stimuli. However, non-speech test results correlate only weakly with evaluations of speech-in-noise processing, cognitive skills, and caregiver evaluations of listening ability. The interpretation of speech test results is confounded by the involvement of language processing mechanisms. Overall, listening ability is associated more with higher-level, cognitive and analytic processing than with lower-level sensory processing. Current diagnosis of a child with APD, rather than another problem (e. g. language impairment, LI), is determined more by the referral route than by the symptoms. Co-occurrence with other learning problems suggests that APD may be a symptom of a more varied neurodevelopmental disorder. Alternately, APD has been proposed as a cause of language-based disorders, but there is no one-to-one mapping between listening and language among individuals. Screening for APD may be most appropriately based on a well-validated, caregiver questionnaire that captures the fundamental problem of listening difficulties and identifies areas for further assessment and management. This approach has proved successful for LI, and may in future serve as a metric to help assess other, objective testing methods. C1 [Moore, David R.] MRC Inst Hearing Res, Nottingham, England.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Frequency compression; cognition; speech-in-noise; trail making test; reading span test ID WORKING-MEMORY; TRANSPOSITION; OUTCOMES AB Objective:The aim was to investigate the relationship between cognitive ability and frequency compressed speech recognition in listeners with normal hearing and normal cognition. Design:Speech-in-noise recognition was measured using Institute of Electrical and Electronic Engineers sentences presented over earphones at 65 dB SPL and a range of signal-to-noise ratios. There were three conditions:unprocessed, and at frequency compression ratios of 2:1 and 3:1 (cut-off frequency, 1.6 kHz). Working memory and cognitive ability were measured using the reading span test and the trail making test, respectively. Study sample:Participants were 15 young normally-hearing adults with normal cognition. Results:There was a statistically significant reduction in mean speech recognition from around 80% when unprocessed to 40% for 2:1 compression and 30% for 3:1 compression. There was a statistically significant relationship between speech recognition and cognition for the unprocessed condition but not for the frequency-compressed conditions. Conclusions:The relationship between cognitive functioning and recognition of frequency compressed speech-in-noise was not statistically significant. The findings may have been different if the participants had been provided with training and/or time to 'acclimatize' to the frequency-compressed conditions.

Design: A literature search of peer-reviewed, published journal articles was conducted in online bibliographic databases. Study sample: Three databases for medical research were included in this review. Results: Mutations in PRPS1 are associated with a spectrum of non-syndromic to syndromic hearing loss. Hearing loss in male patients with PRPS1 mutations is bilateral, moderate to profound, and can be prelingual or postlingual, progressive or non-progressive. Audiogram shapes associated with PRPS1 deafness are usually residual and flat. Female carriers can have unilateral or bilateral hearing impairment. Gain of function mutations in PRPS1 cause a superactivity of the PRS-I protein whereas the loss-of-function mutations result in X-linked nonsyndromic sensorineural deafness type 2 (DFN2), or in syndromic deafness including Arts syndrome and X-linked Charcot-Marie-Tooth disease-5 (CMTX5). Conclusions: Lower residual activity in PRS-I leads to a more severe clinical manifestation. Clinical and molecular findings suggest that the four PRPS1 disorders discovered to date belong to the same disease spectrum. Dietary supplementation with S-adenosylmethionine (SAM) appeared to alleviate the symptoms of Arts syndrome patients, suggesting that SAM could compensate for PRS-I deficiency.

Design: A within-subject design with repeated measures across conditions was used. Speech recognition thresholds in noise were obtained for the different conditions. Study sample: Twenty adults without prior experience with hearing aids. All had symmetric sensorineural mild hearing loss in the lower frequencies and moderate to severe hearing loss in the higher frequencies. Results: Speech recognition performance in noise was not significantly better with an omnidirectional microphone compared to unaided, whereas performance was significantly better with a directional microphone (1.6 dB with open fitting and 4.4 dB with closed earmold) compared to unaided. With open fitting, no significant additional advantage was obtained by combining the directional microphone with a noise reduction algorithm, but with closed earmolds a significant additional advantage of 0.8 dB was obtained. Conclusions: The significant, though limited, advantage of directional microphones and the absence of additional significant improvement by a noise reduction algorithm should be considered when fitting open-fit hearing aids.

Design: Descriptive cross-sectional group design. Study sample: Two hundred HIV positive adult patients (56.5% male; 43.5% female; mean age: 37.99 +/- 6.66 years) attending the Infectious Disease Clinic of a tertiary referral hospital in Pretoria, South Africa were included. Patients were interviewed, medical files were reviewed, and clinical examinations, including otoscopy, tympanometry, pure-tone audiometry, and distortion product otoacoustic emissions, were conducted. A matched HIV negative control group was used to compare hearing loss prevalence. Results: Tinnitus (26%), vertigo (25%) hearing loss (27.5%), otalgia (19%), and ear canal pruritis (38%) were prevalent self-reported symptoms. Abnormalities in otoscopy, tympanometry, and otoacoustic emissions were evident in 55%, 41%, and 44% of patients respectively. Pure-tone average (PTA) hearing loss >25 dBHL was evident in 14% of patients and 39% for hearing loss >15 dBHL (PTA). Significant differences across average thresholds in the HIV positive and HIV negative control group was present. An increase in self reported vertigo, self reported hearing loss, OAE abnormalities, and hearing loss (PTA>15 dBHL and PTA>25 dBHL) was seen with disease progression but was not statistically significant. A significant increase (p<.05) in sensorineural hearing loss was however evident with disease progression. Conclusions: Auditory and otological symptoms are more common in patients with HIV with a general increase of symptoms, especially sensorineural hearing loss, towards advanced stages of disease progression.

Study sample: Thirty-five healthy newborns tested within the first two weeks of birth. Design: In each case cABR and MSSR (0.5 and 2 kHz) were recorded with and without acoustic stimulation, using AUDIX equipment. With this test sample of recordings, ROC curves were evaluated separately for each statistic evaluated: (1) the standard deviation ratio (SDR) and the correlation coefficient ratio (CCR) for the cABR; (2) the Hotelling T2 (HT2) and circular T2 (CT2) for the MSSR. Results: All objective detection methods performed well (areas under ROC (AUC) > 0.9). The MSSR statistics showed significantly larger AUCs at both frequencies (HT2:0.98 and 1; CT2:0.96 and 0.99) than the cABR measures (SDR: 0.91 and CCR: 0.92). The HT2 hits rate was the highest (97-100% at 0.5 and 2 kHz) for fixed false alarms rates of both 10 and 20%. Conclusions: This superiority of performance of T2-like statistics, reflecting inherent advantages of MSSR analysis for automation, warrants serious consideration for further development of newborn screening technology.

Design: PTA was performed at six frequencies at the screening level 20 dB HL. Referral criteria were threshold levels >= 25 dB HL at two or more frequencies for one ear or both. Study sample: 1478 participants aged 7-91 years were included. Results: 1470 (99.5%) people cooperated in screening of which 1325 (90%) could be tested on both ears at all six frequencies. A majority, 987 (66.8%), performed ordinary PTA, 234 (15.8%) conditioned play audiometry, and 249 (16.9%) behavioural observation audiometry. Six hundred and sixty-nine (45%) passed and 809 (55%) failed according to referral criteria. Of those failing, 441 (54.5%) accepted referral to clinical evaluation. Conclusions: PTA with slight modifications is applicable for screening of a population with mild to profound intellectual disability. The most challenging and time-consuming activity is to introduce the test procedure in a way that reduces anxiety and establishes trust.

Study sample: The sample consisted of 242 upper secondary school students aged 15-19 years. Design: Variables defined by the theory of planned behaviour (TBP) and health belief model were tested in this quantitative study. Results: Fifty-three percent of the adolescents reported that they used hearing protection at concerts to some degree, and 33 individuals (14%) reported that they used hearing protection in 50% of cases or more. The average degree of hearing protection use was reported to be 17% of the visits at concerts. Norms, perceived control, barriers, and noise sensitivity were associated with attitudes towards loud music. In addition, norms, barriers, permanent tinnitus, and noise sensitivity were significantly correlated with hearing protection use. However, intention was not significantly correlated with hearing protection use. Conclusions: From a systems theoretical approach it can be suggested that preventive strategies must consider more levels than just the individual, in order to achieve long lasting behavioural changes in adolescents' listening habits. To be able to get useful knowledge about preventive strategies, it is necessary to add context-specific variables into generic models such as TPB.

Design: Open-ended questionnaire. Study sample: Significant others of members of the Finnish Meniere's Federation. Results: The predominant responses concerned effects on their lives and lifestyle-participation restrictions (effects on personal and community life)-and on personal contextual factors (uncertainty of life). In contrast they fail to list such effects of the patients, focussing rather on the patients' symptoms. Five percent of the responses given entailed positive experiences. Conclusions: Significant others of patients with MD listed a wide range of effects of their partner's condition on them. We encourage doctors and therapists to include the significant others in the rehabilitation process to enable them to understand the patient's condition, to help the significant other, and so better support the patients concerned.

Design : A qualitative study was conducted at an audiology clinic at a hospital in South Africa. Data collection included observation and video-recording of assessment and feedback sessions as well as post-session semi-structured interviews with the audiologists and caregivers. Recorded sessions were analysed using sociolinguistic methods and a transcription-less approach. Interviews were analysed via content analysis. Study sample: Participants included four audiologists and five caregivers whose children had been referred for an initial audiological assessment. Results: Feedback sessions included explanations of the hearing mechanism, tests, audiogram, diagnosis and recommendations. Most caregivers were able to recall the final diagnosis and recommendations, but demonstrated poor recall and understanding of explanations of the audiogram and hearing mechanism. Conclusions: Results highlight the importance of tailoring information towards specific caregiver needs during feedback sessions and acknowledging the goals and agenda of the caregiver. There is a need for a greater focus on information counselling in curricula and training programmes, and several suggestions are made in this regard.

Design: Case report. Study sample: Six members of a family participated in an audiological evaluation that included pure-tone audiometry, immittance tests, auditory brainstem responses (ABR), and otoacoustic emissions (OAE). The radiological evaluation was conducted through temporal bone CT scans using a Toshiba 16 channels Aquilon Spirale. Neuropsychiatric evaluation was also administered. Results: Three participants were diagnosed with severe sensorineural hearing loss of cochlear origin and cochlear malformations visible in CT scans. One participant had a mild mixed-hearing loss and no cochlear malformations. Two participants had normal audiological and radiological findings. Conclusions: We believe our study can provide helpful insight on the clinical findings of a rare mutation, of which few data have been presented in literature.

Design: Absorbance was measured in the ear canal over frequencies from 0.25 to 8 kHz at ambient pressure or as a swept tympanogram. CHL was defined using criterion airbone gaps of 20, 25, and 30 dB at octaves from 0.25 to 4 kHz. A likelihood-ratio predictor of CHL was constructed across frequency for ambient absorbance, and across frequency and pressure for absorbance tympanometry. Performance was evaluated at individual frequencies and for any frequency at which a CHL was present. Study sample: Absorbance and conventional 0.226-kHz tympanograms were measured in children of age three to eight years with CHL and with normal hearing. Results: Absorbance was smaller at frequencies above 0.7 kHz in the CHL group than the control group. Based on the area under the receiver operating characteristic curve, wideband absorbance in ambient and tympanometric tests were significantly better predictors of CHL than tympanometric width, the best 0.226-kHz predictor. Accuracies of ambient and tympanometric wideband absorbance did not differ. Conclusions: Absorbance accurately predicted CHL in children and was more accurate than conventional 0.226-kHz tympanometry.

Design: Cochlear tuning measures based on SFOAE phase gradients and SFOAE-2TS 'Q' were used to test this hypothesis. SFOAE magnitude and phase gradient were measured using a pure-tone sweep from 1248 to 2496 Hz at 50 dB SPL. 2TS curves of SFOAE were recorded with a suppressor frequency swept from 1120 to 2080 Hz at 50 dB SPL. DPOAE f2-sweep phase gradient was also obtained to allow comparisons with the literature. All three assays were performed across with-and no-CAS conditions. Study sample: Twenty-two young, normal-hearing adults. Results: CAS did not produce a statistically significant change in the tuning metric in any of the OAE methods used, despite producing significant reductions in the OAE magnitude. Conclusion: It is unknown whether this insensitivity to CAS is due to an insensitivity of these three measures to cochlear mechanical tuning. The results suggest that any changes in tuning induced by CAS that may occur are small and difficult to detect using the OAE measurement paradigms used here.

TI Performance at different stimulus intensities with the within- and across-channel adaptive tests of temporal resolution SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Temporal resolution; gap detection; within-channel; across-channel; ATTR ID HEARING-IMPAIRED LISTENERS; GAP DETECTION THRESHOLDS; IN-NOISE TEST; WITHIN-CHANNEL; BAND STIMULI; FREQUENCY; AGE; SPEECH; DISCRIMINATION; BANDWIDTH AB Objective: The Adaptive Tests of Temporal Resolution (ATTR (c)) software provides within-channel (WC) and across-channel (AC) adaptive measures of temporal resolution that are feasible for clinical applications. The purpose of the present study was to obtain normative values for young adults on two of the ATTR tests: the narrow-band noise within-channel (NBN-WC) test and the narrow-band noise across-channel (NBN-AC) test, at different stimulus intensities. Design: Gap detection thresholds were measured at five sensation levels. A Latin square design was used to control for practice effects. Study sample: The NBN-WC group and the NBN-AC group each consisted of 25 young adults with normal hearing. Results: Gap detection thresholds for both conditions decreased with increasing stimulus intensity, and stimulus intensities above 20 dB SL were not associated with large improvements in performance. Variability was larger in the NBN-AC condition. Values obtained for the NBC-WC condition were very similar to previously reported ATTR results despite equipment and design differences. Conclusion: Results provide normative values for NBN-WC and NBN-AC performance on the ATTR and suggest that the ATTR is a robust test for clinical use.

TI Preferred delay and phase-frequency response of open-canal hearing aids with music at low insertion gain SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aid; open canal; delay; phase; music ID SPEECH PRODUCTION; IMPAIRED SUBJECTS; FITTINGS; LIMITS; DISTURBANCE; PERCEPTION; PATH AB Objective: Preferences between low delays and phase-frequency responses of behind-the-ear, open-canal hearing aids were investigated with acoustic conditions deemed sensitive to delay effects by normal-hearing listeners. Design: Hearing aids with the following selectable delay and phase response options were fitted at low insertion gain: (1) 1.4 ms delay, minimum phase; (2) 3.4 ms delay, minimum phase; and (3) 3.4 ms delay, linear phase. Blind paired comparisons were made between processing options and between each option and a muted hearing-aid output with two music stimuli. The three alternative forced choice responses were "Slightlyprefer", "Prefer ", or "Strongly prefer". Study sample: Twelve hearing-impaired musicians. Results: At the 3.4-ms delay, the minimum-phase response was significantly preferred to the linear-phase response for one music sample and vice-versa for the other sample with a sign test (p < 0.04) but not a Wilcoxon signed rank test that accounted for the low preference strength. Preferences between all other processing conditions were not significant. Conclusions: In acoustic conditions sensitive to delay effects, delays of 1.4 or 3.4 ms were either not detected or no less preferable than no delayed aided signal. It is unclear whether different phase-frequency responses may be preferred with different music stimuli.

Design and study sample: A retrospective evaluation of the clinical outcomes of 70 tinnitus patients fitted with hearing aids was undertaken. The primary outcome measure was the TRQ, with a secondary subjective measure of tinnitus masking. Results: Participants who achieved masking with their hearing aids had greater reduction in TRQ scores. Masking was more likely to be achieved when participants had good low-frequency hearing and tinnitus pitch fell into the frequency range of the hearing aids. Conclusions: The results support the use of hearing aids for tinnitus management, and suggest that masking may be a significant contributor to hearing aid success, implying that high-frequency amplification may be effective in high-pitch tinnitus.

We aimed to investigate the relationship of WC and pitch pattern sequence (PPS) score in adults. Design: The association of WC with PPS score was analysed. Study sample: Volunteer helpers at a community hospital, 391 adults >= 40 years, with normal or symmetrical sensorineural hearing loss were randomly selected. Results: After adjusting for age, gender, pure-tone average, systemic diseases, and habits, WC was significantly negatively associated with PPS. In a subgroup analysis by gender and age, the PPS score was negatively associated with WC only for males who were older than 55 years old, but not for males who were younger than 55 years old or females in either age group. Meanwhile, central obesity showed positive association with abnormal PPS recognition ability (PPS score < 90%) of borderline significance only for males who were older than 55 years old, but not for males who were younger than 55 years old or females in both age groups. Conclusions: WC or central obesity is an independent risk factor for poor central auditory function, especially in older male subjects.

The aim of this study was to compare the phoneme /integral/ from word medial and word initial positions and its influence on the CAEP. Design: Stimuli from word medial positions were found to have shorter rise times compared to the same phonemes from word initial positions. A repeated measures design was carried out with CAEPs elicited using /integral/ from a word initial and a word medial position. Study sample: Sixteen individuals with audiometric thresholds within normal limits participated in the study. Results: Stimuli /integral/ from a word medial position elicited CAEPs with significantly larger amplitudes and shorter latencies compared to /integral/ from a word initial position (p < 0.05). Conclusions: Findings from this study, incorporating naturally produced speech sounds, suggest the need to consider spectral and temporal variations when choosing stimuli to optimize the amplitude and latency characteristics of the CAEP. Overall, findings illustrate good test-retest reliability of CAEP measures using speech stimuli with clinical equipment.

Design: The percentage hearing losses of war veterans who had hearing ranging from normal to profound deafness were determined and compared with their scores on two hearing questionnaires. Study sample: A self-report hearing questionnaire was completed by 282 war veterans and 154 of those veterans were given the hearing measurement scale in the form of a structured interview. Results: A percentage loss of hearing of 0 agreed well with the questionnaire scores representing the limit of normal hearing, and a percentage loss of hearing of 100 agreed well with the questionnaire scores representing total loss of hearing. Percentage loss of hearing accounted for 83% of the variance in scores on the hearing questionnaire and 81% of the variance in scores on the hearing measurement scale. Conclusion: The National Acoustic Laboratories procedure for determining percentage loss of hearing provides a valid measure of hearing disability.

Design: Hearing thresholds were determined monaurally for broad-band chirps and octave-band chirps using the Etymotic Research, ER-3A insert earphone. The chirps were presented using two repetition rates, 20 and 90 stimuli/s, and with alternating polarity in blocks of one second duration. The test procedure and test conditions were in accordance with the recommendations given in ISO 389-9 (2009). The ascending method (ISO 8253-1, 2010) was applied using a step size of 5 dB. The chirps were played back from a Tucker Davies Technologies System II, and a Matlab program controlled the test setup. The results are specified in dB peak-to-peak equivalent threshold sound pressure levels (dB peETSPL). Study sample: The test group consisted of 25 otologically-normal young adults (age 18-25 years). Results: The results are in good agreement with the results from another investigation of hearing thresholds using the same chirp stimuli, and the values for the octave-band chirps are in line with the standardized reference values for corresponding tone bursts (ISO 389-6, 2007). Conclusions: The results of the present investigation are relevant for the international standard on short duration signals, ISO 389-6 (2007).

Design: Case-control study. Genetic and acquired risk factors of these three groups were compared with healthy controls. Study sample: Forty-nine, 60, and 101 patients affected respectively by sudden sensorineural hearing loss, central retinal vein occlusion, or stroke associated with small vessel disease, enrolled during a three-year period were compared with 210 healthy controls. Results: The frequency of hyperhomocysteinemia (homocysteine >= 15 mu mol/L) was higher in each disease group than in controls. A statically significant, albeit weak, correlation between the MTHFR C677T mutation and hyperhomocysteinemia was found in all three diseases. Conclusions: Hyperhomocysteinemia proved to be a risk factor for sudden sensorineural hearing loss. Based on these results, we propose to analyse homocysteine in sudden sensorineural hearing loss patients and, if its values are high, to evaluate the presence of MTHFR C677T mutation.

Design: Baseline performance of clinically created CI settings was evaluated objectively (CNC and BKB-SIN) and subjectively (listening situation questionnaire). Participants underwent the Clarujust optimization procedure during two sessions, each two weeks apart, allowing for acclimatization and experience with each group of programs. Outcome testing was completed on both optimization settings during the two week follow-up session. CNC and BKB-SIN scores were compared within participants across test sessions. Study sample: Twenty adult experienced CI users were reprogrammed using the Clarujust T fitting procedure. Results: Significant improvements (p < 0.05) on CNC words and BKB-SIN sentences were observed with optimized maps compared to maps programmed using standard methods. Subjective performance also showed increased satisfaction with the optimized maps. The maps for individual users varied significantly and no single fitting applied for all patients. Conclusions: The Clarujust optimization method of programming CIs shows promise to improve patient performance and increase patient satisfaction in a shorter clinical test time.

Design: Bilateral performance was compared to performance of the implanted side with the best monaural speech recognition in quiet result. Parental reports were collected in a questionnaire. Results from the CI children were compared to binaural and monaural performance of normal-hearing peers. Study sample: Sixty-four children aged 5.1-11.9 years who were daily users of bilateral cochlear implants. Thirty normal-hearing children aged 4.8-9.0 years were recruited as controls. Results and Conclusions : Group data showed a statistically significant bilateral speech recognition and sound localization benefit, both behaviorally and in parental reports. The bilateral speech recognition benefit was smaller in quiet than in noise. The majority of subjects localized high and low frequency sounds significantly better than chance using bilateral implants, while localization accuracy was close to chance using unilateral implants. Binaural normal-hearing performance was better than bilateral performance in implanted children across tests, while bilaterally implanted children showed better localization than normal-hearing children under acute monaural conditions.

Furthermore, subject-related factors possibly associated with hearing impairment (HI), i.e. handedness, eye color, and susceptibility to sunburn, were studied. Design: A cross-sectional, unscreened, population-based, epidemiological study among adults. Study sample: The subjects (n = 850), aged 54-66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed. Results: Chronic middle-ear disease (both active and inactive) was the most common ear disease with a prevalence of 5.3%, while the prevalence of otosclerosis was 1.3%, and that of Meniere's disease, 0.7%. Noise exposure was reported by 46% of the subjects, and it had no effect on hearing among those with no ear disease or other otological risk factors for HI. Dark eye color and non-susceptibility to sunburn were associated with HI among noise-exposed subjects. Conclusions: Common ear diseases and other otological risk factors constitute a major part of the etiologies of HI among adults. Contrary to previous studies, noise exposure turned out to have only marginal effect on hearing among those with no otological risk factors.

Document evidence of early prelingual auditory development (EPLAD), identify factors that affect EPLAD, and define performance milestones that can guide best practices. Design: Unblinded, prospective, within-subject, repeated-measures design. Audiological measures and measures of EPLAD were taken at baseline, 3, 6, and 12 months after hearing-aid fitting. Study sample: Subjects were 45 pediatric patients initially fitted with hearing aids between 1 and 5.5 years of age. Four groups were formed for analysis purposes based on severity of hearing loss (moderate-to-severe and profound) and initial fitting age (<= 30 months and > 30 months). Results: All groups exhibited statistically significant increases in EPLAD within six months of hearing-aid fitting, and those with profound losses exhibited further statistically significant improvement between six and 12 months. Similar EPLAD levels were reached at 12 months regardless of severity of hearing loss. The EPLAD trajectory is similar to that following early cochlear implantation. Conclusions: Measures of EPLAD provide a means of evaluating outcomes following early pediatric hearing-aid intervention, supplementing behavioral audiological measures.

Design: Monaural TFS sensitivity was assessed using the TFS1 test (Moore & Sek, 2009) at centre frequencies of 850 and 2000 Hz, and binaural TFS sensitivity was assessed using the TFS-LF test (Hopkins & Moore, 2010a) at centre frequencies of 500 and 850 Hz, using a sensation level of 30 dB. Study sample: Thirty-five newly recruited normal-hearing subjects (thresholds better than 20 dB HL from 250 to 6000 Hz) were tested. Their ages ranged from 22 to 61 years. Results: There was a significant correlation between age and TFS sensitivity at all frequencies for both TFS tests. For the single centre frequency (850 Hz) that was used for both tests, scores for the two tests were modestly but significantly correlated. Conclusions: Sensitivity to TFS decreases with increasing age. The monaural and binaural TFS tests appear to reflect at least somewhat distinct auditory processes. C1 [Moore, Brian C.

Design: HQ-scores and uncomfortable loudness levels (ULLs) were assessed in 348 individuals (140 men and 208 women) with low, intermediate, and high EE-levels. Results: Four individuals (1.1%) met the critical value for hyperacusis according to the HQ. An exploratory factor analysis extracted three factors from the HQ accounting for 57.6% of the variance. Internal consistency was acceptable for all subscales and for the total score, with Crohnbach's alpha ranging from 0.65 to 0.86. When controlling for hearing loss, significant correlations between the HQ and ULLs were found on both ears in those with intermediate (right: -0.328; left: -0.320) and high EE (right: -0.349; left: -0.393), but not with low EE (right: -0.204; left: -0.196). All correlations were negative, indicating that higher HQ-scores are correlated with lower ULLs. The strongest correlations were found for the social dimension, indicating that social aspects may correspond best to audiological parameters (ULLs) of hyperacusis. Conclusions: The results emphasize the need to take other factors, such as emotional exhaustion (long-term stress), into consideration when assessing hyperacusis with a questionnaire.

Marshall, Lynne TI Measurements of earplug attenuation under supra-aural and circumaural headphones SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing protection; HPD; earplugs; attenuation; fit-testing; supra-aural; circumaural; headphones; TDH AB Objective: Supra-aural audiometric headphones are generally not recommended for use in measuring the attenuation of earplugs, because contact between the headphone and pinna and/or earplug could alter the attenuation obtained, and because of concerns of non-comparability between modes of excitation from supra-aural headphones and the sound-field procedure required by the standardized method. In this study, we compared measurements of earplug attenuation obtained under Telephonics TDH-50P supra-aural headphones with measurements obtained under circumaural headphones designed expressly for such testing. Design: The attenuation of three types of earplugs (foam, premolded quadruple-flange, and custom-molded) was measured in a repeated-measures design. Study sample: The study sample comprised 42 normal-hearing adults (21 females, 21 males). Results: With the foam earplugs, nearly all of the attenuation measurements under the supra-aural headphones fell within 10 dB of the measurements under the circumaural headphones. With the flange and custom earplugs, approximately 10% of individuals obtained spuriously high attenuation under the supra-aural headphones. Conclusions: We conclude that standard supra-aural audiometric headphones are suitable for measuring the attenuation provided by foam earplugs. However, supra-aural headphones should not be used to measure the attenuation of flange or custom-molded earplugs. The potential exists for substantial over-estimation of attenuation, especially of custom plugs. C1 [Tufts, Jennifer B.; Palmer, Jillian V.] Univ Connecticut, Dept Commun Sci, Storrs, CT 06269 USA.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Respect; people with hearing aids; medical students; hearing-aid effect ID CLOSE RELATIONSHIPS; ATTITUDES; COMMUNICATION; PERCEPTIONS; AMERICAN; CARE AB Objective: To investigate, in line with the "hearing-aid effect", whether medical students would have less respect for a young male with a hearing aid than without when he was described as either respectworthy (i.e. as deserving respect) or non-respectworthy, and whether their attitudes differed from non-medical students. The interaction between the presence/absence of a hearing aid and respectworthiness on respect level was also explored. Design: Participants were shown a photograph and a written description of a young male. They were pseudo-randomly assigned to one of four core conditions reflecting the presence or absence of a hearing aid and the young man's respectworthiness, and completed questions regarding their behaviours, beliefs, and feelings of respect towards him. Study sample: One hundred and eighty-one medical students and a control group of 92 non-medical students. Results: Results showed more respect for the young male with a hearing aid than without from female participants, and for the young male described as respectworthy compared to non-respectworthy in medical and in non-medical students. However, medical students had more respect for the young male with and without a hearing aid than non-medical students. Conclusions: Findings were contrary to the "hearing-aid effect". Possible explanations are given and implications are discussed. C1 [Clucas, Claudine; St Claire, Lindsay] Univ Bristol, Ctr Hearing & Balance Studies, Bristol BS8 1TN, Avon, England.

TI Prediction of aided and unaided audiograms using sound-field auditory steady-state evoked responses SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory steady state evoked response; hearing aids; amplitude growth function; sound field ASSR; objective fitting ID BRAIN-STEM RESPONSE; HEARING-AIDS; AUDIOMETRY; SELECTION; CHILDREN; INFANTS; FREQUENCY; THRESHOLDS; AMPLITUDE; ONSET AB Objective: To assess sound field auditory thresholds of hearing-impaired adults by using auditory steady-state evoked responses (ASSRs). Design: ASSRs were recorded to carrier frequencies of 500, 1000, 2000, and 4000 Hz, each uniquely modulated at a single frequency of 80-100 Hz. ASSR thresholds were compared to behavioral auditory thresholds. Study sample: Twenty adults (11 male, age 35.6 years) with moderate-severe sensorineural hearing loss who had used hearing aids, and 10 normal-hearing subjects (mean age 22.4 years). Results: For most frequencies, behavioral sound-field thresholds were slightly lower than ASSR thresholds in both aided and unaided conditions, with a significant correlation between them. Differences between ASSR and behavioral thresholds ranged between 516 dB in the unaided and between 5-16 dB in the aided condition. The ASSR amplitude growth function to 2000 Hz was steeper in both the aided and unaided conditions than in the normal-hearing group. Conclusions: Sound-field ASSRs can predict behavioral auditory thresholds in both the unaided and aided condition, as well as behavioral functional gains. The ASSR growth function for 2000 Hz is suggested to reflect an underlying mechanism of intensity encoding common to abnormal loudness perception frequently reported in cases of cochlear hearing loss.

Forsline, Anna TI Hearing-aid counseling: Comparison of single-session informational counseling with single-session performance-perceptual counseling SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aids; rehabilitation of hearing impaired; counseling ID MEDICAL INFORMATION; REPORTED HANDICAP; OLDER-PEOPLE; ADULTS; USERS; IMPAIRMENT; OUTCOMES; PROGRAM; MEMORY; INVENTORY AB Objective: Hearing-aid counseling can improve outcome but programs are often too resource-intensive to be clinically practical. Here we examined the effectiveness of single-session informational counseling with single-session performance-perceptual counseling. Design: Two forms of counseling were compared: informational counseling (IC) and performance-perceptual counseling (PPC). IC focused on discussing communication strategies and tips for hearing-aid use. PPC addressed the discrepancy between measured and perceived ability to understand speech. Outcomes were measured eight-to-ten weeks post-counseling using quantitative and qualitative measures: Hearing handicap inventory, abbreviated profile of hearing aid benefit, psychosocial impact of assistive devices scale (PIADS), international outcome inventory for hearing aids, and a semi-structured exit interview. Study sample: Seventy-four hearing aid-users with symmetrical sensorineural hearing loss participated. Results: Scores on the hearing questionnaires showed no change following either form of counseling. Scores on the PIADS improved for participants as a whole, and the semi-structured interview revealed increased hearing-aid use, better understanding and acceptance of hearing loss, increased use of communication strategies, and improved ability to explain hearing difficulties to others. Conclusions: A single session of hearing-aid counseling can improve hearing-aid use and satisfaction. Open-ended interview and/or quality of life measures are more sensitive to these benefits than hearing questionnaires.

TI Firefighter hearing health: An informatics approach to screening, measurement, and research SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Informatics; Omaha System; firefighters; hearing ID NOISE; WORKERS AB Objective: The purpose of this study was to evaluate the use of a standardized interface terminology, the Omaha System, with respect to noise-induced hearing loss (NIHL). Design: A descriptive, correlational design was employed for this secondary analysis with the data from an ongoing hearing protection intervention study. Study sample : A total of 346 firefighters were included. Results: First, an evidence-based standardized care plan (EB-SCP) for hearing screening was developed and validated by clinical experts. Second, occupational health records were used to compute Omaha System Knowledge, Behavior, and Status outcomes. Third, research data were mapped to Omaha System rating scales. For Knowledge, the mean score was close to 'adequate' (3.7). For Behavior, the mean score was close to 'rarely appropriate' (2.2). For Status, the mean score was close to 'minimal sign/symptom' (4.4). Significant positive relationships were found between Knowledge and Behavior (Spearman's rho = .13, p = .01), and between Behavior and hearing Status (Spearman's rho = .12, p = .02). Conclusions: Findings support the validity of the new Knowledge, Behavior, and hearing Status. Informatics methods such as the standardized NIHL EB-SCP and outcome data sets will create opportunities for clinical decision support and data exchange across various health care settings, thus supporting population-based hearing health assessments and outcomes.

TI Auditory discrimination: The relationship between psychophysical and electrophysiological measures SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory evoked potential; auditory event-related response; auditory discrimination ID CORTICAL EVOKED-POTENTIALS; AGE-RELATED DIFFERENCES; ACOUSTIC CHANGE; FREQUENCY DISCRIMINATION; INTENSITY DISCRIMINATION; SPECTRAL ENVELOPE; CHANGE COMPLEX; C-PROCESS; GAPS; NEUROPATHY AB Objectives: This study aimed to (1) investigate the relationship between the acoustic change complex (ACC) and perceptual measures of frequency and intensity discrimination, and gap detection; and (2) examine the effects of acoustic change on the amplitudes and latencies of the ACC. Design: Psychophysical thresholds for frequency and intensity discrimination and gap detection, as well as ACCs elicited by stimuli containing increments in frequency, or intensity or gaps, were recorded from the same group of subjects. The magnitude of the acoustic change was systematically varied for the ACC recording. Study sample: Twenty-six adults with normal hearing, ranging in age between 19 and 39 years. Results: Electrophysiological and psychophysical measures for frequency and intensity discrimination were significantly correlated. Electrophysiological thresholds were comparable to psychophysical thresholds for intensity discrimination but were higher than psychophysical thresholds for gap detection and frequency discrimination. Increasing the magnitude of acoustic change increased the ACC amplitude but did not show consistent effects across acoustic dimensions for ACC latency. Conclusions: The ACC can be used as an objective index of auditory discrimination in frequency and intensity. The ACC amplitude is a better indicator for auditory processing than the ACC latency.

Design: Retrospective case review from a tertiary referral center. Study sample: Thirty patients suspected to have Meniere's disease were assessed by ECochG and CHAMP tests. Results: Positivity of ECochG with SP/AP amplitude ratio >.40 or >.35 was compared with CHAMP V-delay or CHAMP R x D. Positive ECochG results were found in 43% (>.40 SP/AP ratio) and 63% (>.35 SP/AP ratio) of patients, comparing to positive CHAMP V delay in 27% and CHAMP R x D in 30% of patients. A significant difference (p < .01) was found between ECochG and CHAMP in diagnostic sensitivity. Also, a positive inter-aural correlation was found in CHAMP results (p < .003), but not in ECochG (p = .082) results. Conclusions: ECochG is a more sensitive test than CHAMP in detecting the presence of endolymphatic hydrops in Meniere's patients. CHAMP covaried interaurally in unilateral Meniere's patients whereas ECochG did not. C1 [Angelo, Richard M.; Yue, Qing] Bloomsburg Univ Penn, Dept Audiol & Speech Pathol, Bloomsburg, PA 17815 USA.

Study sample: In total, 64 people who had obtained hearing aids completed both IOI-HA versions and 27 people who had participated in communication programs completed both IOI-AI versions. Results: Participants reported higher scores on the modified (word) daily-use item than on the original (number) daily-use item. Participants who completed the IOI-AI did so significantly more than participants who completed the IOI-HA. This was true both after intervention completion and three months later. Conclusion: This study showed that comparisons between IOI-HA and IOI-AI daily-use item scores should be made with caution. Word daily-use response options are recommended for the IOI-AI (i.e. Never; Rarely; Sometimes; Often; and Almost always).

Design: Students were screened for their hearing at frequencies 2, 4, and 6 kHz and at a level of 20 dB HL. Failure of the screening was defined by missing at least one frequency in one ear. In addition to hearing screening, the students filled out a questionnaire asking for practices related to exposure to loud music. Study sample: 1296 adolescents aged 14 to 15 years. Results: The overall rate of failing the hearing screening was 14.9% (95% CI: 13.0% -16.8%). The rate was similar in adolescents with no, little, or moderate exposure to loud music (10% to 15%), but significantly increased (22% to 25%) in adolescents with high exposure. Conclusions: The observed failing rate compares well to findings on the prevalence of hearing deficits in adolescents reported in other studies. In addition, our study suggests that the risk for hearing damage from loud music is not steadily increasing with increase of exposure, but exists only under conditions of extreme listening.

Design: CAEP recordings to speech-based stimuli were made at three presentation levels (55, 65, or 75 dB SPL) when a group of hearing-impaired infants were either aided or unaided. Later-obtained behavioral audiograms were used as the gold standard against which to evaluate the accuracy of the automatic detection of the presence/absence of CAEP responses. Study sample: Participants were 18 infants with confirmed sensorineural hearing loss. Results: Higher sensation levels led to a greater number of present CAEP responses being detected. More CAEP waveforms were detected in the aided condition than in the unaided condition. Conclusion: Our results suggest that the presence/absence of CAEP responses defined by the automatic statistical criterion was effective in showing whether increased sensation levels provided by amplification were sufficient to reach the cortex. This was clearly apparent from the significant increase in cortical detections when comparing unaided with aided testing.

Design: Prospective, observational study conducted in seven countries, using linguistically harmonized versions of the THI-12 in six languages. These were evaluated for test-retest reliability, internal consistency reliability, known-groups validity, and construct validity. Basic psychometric properties of supporting instruments were compared. Questionnaires were completed by the subjects at baseline and again after 12-30 days. Study sample: Adults with a clinical diagnosis of subjective tinnitus. Results: An exploratory factor analysis of the THI-12 items for the U. S. study population at baseline revealed a single common factor of high eigenvalue. Confirmatory factor analysis supported this in the separate countries. Test-retest reliability was moderate to high, and the conclusions were supported by a known-groups analysis; correlations with other scales expected to support construct validity were moderate. Conclusions: The THI-12 total score showed acceptable psychometric properties for all countries tested. The relationships between the THI-12 and the one-month and one-week versions of the TRS and TSS were similar and convergent. The THI-12 is thus a promising diagnostic tool for assessing treatment effects in multi-cultural and multi-lingual trials on tinnitus therapy.

This study investigates Danish hearing-aid users' ANL performance using Danish and non-semantic speech signals, the repeatability of ANL, and the association between ANL and outcome of the international outcome inventory for hearing aids (IOI-HA). Design: ANL was measured in three conditions in both ears at two test sessions. Subjects completed the IOI-HA and the ANL questionnaire. Study sample: Sixty-three Danish hearing-aid users; fifty-seven subjects were full time users and 6 were part time/non users of hearing aids according to the ANL questionnaire. Results: ANLs were similar to results with American English speech material. The coefficient of repeatability (CR) was 6.5-8.8 dB. IOI-HA scores were not associated to ANL. Conclusions: Danish and non-semantic ANL versions yield results similar to the American English version. The magnitude of the CR indicates that ANL with Danish and non-semantic speech materials is not suitable for prediction of individual patterns of future hearing-aid use or evaluation of individual benefit from hearing-aid features. The ANL with Danish and non-semantic speech materials is not related to IOI-HA outcome.

TI Accuracy of distortion-product otoacoustic emissions-based ototoxicity monitoring using various primary frequency step-sizes SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Distortion-product otoacoustic emissions; ototoxicity monitoring; cisplatin; fine structure ID FINE-STRUCTURE; MODEL AB Objective: A cisplatin ototoxicity monitoring protocol was recently proposed using distortion-product otoacoustic emissions (DPOAEs) measured in 1/48th octave steps over the highest obtainable quarter octave (Dille et al, 2010). This protocol can take up to 40 minutes to complete in both ears among seriously ill patients in a potentially noisy test environment. The goal of the current study was to contrast the diagnostic accuracy of ototoxicity monitoring protocols based on changes in DPOAE levels at wider, more rapidly tested, primary frequency step sizes. Design: Measure DPOAE levels in 1/48th octave steps over the highest half-octave of obtainable DPOAEs prior to treatment and at each ototoxicity monitoring session during the course of treatment with cisplatin. Study sample: Nineteen cancer patients being treated with cisplatin at the Portland Veterans Affairs Medical Center were observed over 56 monitoring appointments. Hearing thresholds in the sensitive region for ototoxicity (SRO) were measured concurrently with DPOAE levels. Results: DPOAE levels measured in 1/24th octave steps provided comparable accuracy, and half the testing time, to the 1/48th octave step protocol previously described. Conclusions: DPOAE level shifts measured in 1/24th octave steps may provide a basis for rapid ototoxicity monitoring among adult cancer patients treated with cisplatin.

McArdle, Rachel TI Speech-in-noise measures: Variable versus fixed speech and noise levels SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory perception; hearing loss; speech perception; speech recognition in multitalker babble ID INTELLIGIBILITY; RECOGNITION AB Objective: The purpose was to determine if speech-recognition performances were the same when the speech level was fixed and the noise level varied as when the noise level was fixed and the speech level varied. Design: A descriptive/quasi-experimental experiment was conducted with Lists 3 and 4 of the revised speech perception in noise (R-SPIN) test, which involves high predictability (HP) and low predictability (LP) words. The R-SPIN was modified into a multiple signal-to-noise paradigm (23-to -1-dB in 3-dB decrements) from which the 50% points were calculated with the Spearman-Karber equation. Study sample: Sixteen young listeners with normal hearing and 48 older listeners with pure-tone hearing losses participated. Results: The listeners with normal hearing performed better than the listeners with hearing loss on both the HP and LP conditions. For both groups of listeners, (1) performance on the HP sentences was better than on the LP sentences, and (2) the mean 50% points were 0.1 to 0.4 dB lower (better) on the speech-variable, babble-fixed condition than on the speech-fixed, babble-variable condition. Conclusions: For practical purposes the <= 0.4-dB differences are not considered noteworthy as the differences are smaller than the decibel value of one word on the test (0.6 dB).

This study validates a new TEOAE-AABR screening device. Design: TEOAE and AABR screenings were performed in 299 ears with both the new NHS device and a well-established and validated one. Furthermore, 49 ears, suspected of having a hearing loss, underwent the screenings and an additional diagnostic ABR. Study sample: One hundred and fifty newborns and infants were included in the study (median age 1.0 months, range 0-54 months; among them 39 babies from neonatal intensive care units). Results: Screening with both devices resulted in a concordance of. kappa=.98 for TEAOE measurements and .96 for AABR measurements. The mean measurement durations were significantly shorter for the new device than for the established one for both TEOAE (15.4 vs. 17.2 s) and AABR (26.6 vs. 32.7 s). Conclusions: The algorithm of the new screening device is as valid as that for the established one. The shorter test durations with the new device facilitate hearing screenings and allow for a higher number of valid measurements in restless children than with former comparable procedures.

Design : Paragraph-length narratives were presented for recall under two listening conditions in a within-participants design: presentation without interruption (continuous) at an average speech-rate of 150 words per minute; and presentation interrupted at periodic intervals at which participants were allowed to pause before initiating the next segment (self-paced). Study sample : Participants were 24 adults ranging from 21 to 33 years of age. Half had age-normal hearing acuity and half had mild-to-moderate hearing loss. The two groups were comparable for age, years of formal education, and vocabulary. Results : When narrative passages were presented continuously, without interruption, participants with hearing loss recalled significantly fewer story elements, both main ideas and narrative details, than those with age-normal hearing. The recall difference was eliminated when the two groups were allowed to self-pace the speech input. Conclusion : Results support the hypothesis that the listening effort associated with reduced hearing acuity can slow processing operations and increase demands on working memory, with consequent negative effects on accuracy of narrative recall.

TI Newborn hearing screening in youth health care in the Netherlands: National results of implementation and follow-up SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Universal neonatal hearing screening (UNHS); implementation; youth health care; hearing loss (HL); newborn ID BRAIN-STEM RESPONSE; PROGRAM; EXPERIENCE; CHILDREN; IMPAIRMENT; CHILDHOOD; LANGUAGE; COSTS AB Objective: The aim of this study is to investigate whether the quality of the Dutch, community based, universal newborn hearing screening programme is consistent over time. Design: Universal newborn hearing screening data from three cohorts are compared on a number of quality targets concerning the outcome of the screening and the process of the screening in a three stage, community based, hearing screening programme. Study sample: A total of 552 820 children entered the study (189 794 in 2002-2006; 181 574 in 2008, and 181 452 in 2009). Results: Participation in the programme is high from implementation onwards and increases over time for all screen stages to percentages above 99%. Refer rates are within quality targets and they are consistent over time. The screening is completed within 42 days of birth for 91.5% of the children in the last cohort. Of all children screened, 0.29% to 0.30% are referred to a speech and hearing centre. Participation in diagnostic testing is 93.3% to 95.2%. Of all referred children 77% to 85% receive a diagnosis within 122 days of birth. Conclusions: A good quality neonatal hearing screening programme in youth health care has been established in the Netherlands. However, both participation in diagnostic testing after a positive screen result and the timing of the diagnostic testing can still be improved. C1 [Uilenburg, N. N.; Kauffman-de Boer, M.

However, it is not known how these two factors interact. The present study aims to explore this interaction when amplitude (intensity) and phase (time) shifts occur simultaneously. Design: Participants listened to dichotically presented pairs of consonant-vowel syllables (216 trials) under nine different experimental conditions, systematically varying amplitude (+9 dB) and phase (+35 ms) shifts. Participants reported which syllable they perceived on each trial. Study sample: Thirty-two healthy adults. Results: The results showed an expected right ear advantage (REA) in the baseline (nosound manipulation) condition. While amplitude shifts favoring the right ear were found to have a greater effect on REA than phase shifts, phase shifts favoring the left ear were found to have a greater effect on left ear advantage (LEA) than amplitude shifts. Furthermore, phase shifts favoring the left ear had a greater effect on LEA than phase shifts favoring the right ear on REA. Conclusions: Present results may have consequences for the training of individuals with auditory and phonetic difficulties, e. g. auditory processing deficits or dyslexia, by aiding the design of optimal combinations of acoustic and phonetic training tools.

This study obtained such data for Russian natives in the US and analysed the data using the perceptual assimilation model (PAM) and speech learning model (SLM). Design: Listeners were randomly presented 200 NU-6 words in quiet. Listeners responded verbally and in writing. Performance was scored on words and phonemes (word-initial consonants, vowels, and word-final consonants). Study sample: Seven normal-hearing, adult monolingual English natives (NM), 16 English-dominant (ED), and 15 Russian-dominant (RD) Russian natives participated. ED and RD listeners differed significantly in their language background. Results: Consistent with the SLM, NM outperformed ED listeners and ED outperformed RD listeners, whether responses were scored on words or phonemes. NM and ED listeners shared similar phoneme error patterns, whereas RD listeners' errors had unique patterns that could be largely understood via the PAM. RD listeners had particular difficulty differentiating vowel contrasts /i-I/, /ae-epsilon/, and /a-A/, word-initial consonant contrasts /p-h/and /b-f/, and word-final contrasts /f-v/. Conclusions: Both first-language phonology and second-language learning history affect word and phoneme recognition. Current findings may help clinicians differentiate word recognition errors due to language background from hearing pathologies.

Design: Cross-sectional within a comparative study of subjects. Study sample: Subjects were 100 Chinese adults who attended the audiology clinic in a hospital for a hearing test. Results: There was no significant difference in the thresholds of unmasked air-conduction hearing obtained with the computerized self-administered hearing test via a smartphone and those obtained with standard pure-tone audiometry. High test-retest reliability was observed with the self-administered hearing test (intraclass correlation coefficient = 0.95), and was comparable with that observed in standard pure-tone audiometry (intraclass correlation coefficient = 0.97). The thresholds of the self-administered hearing test measured in a sound-proof booth were not significantly different from those measured in a quiet office room. Conclusions: The results suggest that the computerized self-administered hearing test is a reliable and valid measure of unmasked air-conduction hearing thresholds.

Design: A group of tinnitus subjects with hyperacusis was compared to tinnitus subjects without hyperacusis, and healthy controls. For assessing noise avoidance, a questionnaire was developed (noise avoidance questionnaire, NAQ) and the duration of self-exposure to a pure tone was assessed as a behavioral index. Different self-rating instruments concerning tinnitus (STI, TF-12), hyperacusis (GUF), and anxiety (BAI, STAI-T) were used, as well as a psychoacoustic indicator of hyperacusis (ULL). Study sample: Fifty-six tinnitus subjects with/without hyperacusis and 30 controls without tinnitus and hyperacusis participated in the experiment. Results: The findings indicate that subjects with hyperacusis reported significantly more noise-related avoidance in daily life and show significantly shorter exposure to a pure tone than non-hyperacusic subjects, while discomfort was at the same level for each individual. Self-reported avoidance behavior correlated significantly with distress attributed to hyperacusis (r = 0.81), and with anxiety ratings. Conclusions: These results suggest that hyperacusis is associated with noise-related avoidance behavior and anxiety. Systematic exposure to sound could play a significant role in the treatment of hyperacusis.

Design: Two keyword pairs (hearing loss and hearing aids) were entered into five country-specific versions of the most commonly used internet search engine in May 2011. Sample: For each of the 10 searches, the first 10 relevant websites were included. After removing duplicates, a total of 66 websites were assessed. Their origin (commercial, non-profit organization, or government), date of last update, quality (Health On the Net (HON) certification and DISCERN scores), and readability (Flesch Reading Ease Score, Flesch-Kincaid Grade Level Formula, and Simple Measure Of Gobbledygook) were assessed. Results: Most websites were of commercial origin and had been updated within the last 18 months. Their quality and readability was highly variable. Only 14% of the websites had HON certification. Websites that were of non-profit organization origin had significantly higher DISCERN scores. Readability measures show that on average, only people with at least 11-12 years of education could read and understand the internet information presented. Conclusions: Based on these results, this article provides a list of recommendations for website developers and clinicians wishing to incorporate internet information into their practice.

This study tests to what extent novel model-based processing schemes might improve performance in particular for non-stationary noise conditions. Design: Two prototype model-based algorithms, a speech-model-based, and a auditory-model-based algorithm were compared to a state-of-the-art non-parametric minimum statistics algorithm. A speech intelligibility test, preference rating, and listening effort scaling were performed. Additionally, three objective quality measures for the signal, background, and overall distortions were applied. For a better comparison of all algorithms, particular attention was given to the usage of the similar Wiener-based gain rule. Study sample: The perceptual investigation was performed with fourteen hearing-impaired subjects. Results: The results revealed that the non-parametric algorithm and the auditory model-based algorithm did not affect speech intelligibility, whereas the speech-model-based algorithm slightly decreased intelligibility. In terms of subjective quality, both model-based algorithms perform better than the unprocessed condition and the reference in particular for highly non-stationary noise environments. Conclusion: Data support the hypothesis that model-based algorithms are promising for improving performance in non-stationary noise conditions.

Design: Case study of a 5-year-old female who presented with a complaint of headaches, accompanied with a history of symptoms that could be associated with a left unilateral congenital auditory neuropathy. She was later diagnosed with a large, left-sided posterior fossa mass determined to be a JPA. Study sample: Case study of a child identified at birth with a constellation of symptoms consistent with unilateral auditory neuropathy spectrum disorder (ANSD). Results: The early onset symptoms, that can be the same for ANSD or for a brainstem tumor that involves the auditory nerve, suggests that the JPA was congenital. This child, if initially followed by neurology may not have been identified earlier with this tumor, however a baseline MRI or monitoring neuroimaging may have been available for reference or led to earlier detection of the lesion. It may not have changed her management, however, this case stresses the importance of the recommendations in the 'Guidelines for Identification and Management of Infants and Young Children with Auditory Neuropathy Spectrum Disorder' that include a referral to a neurologist for a baseline assessment and neuroimaging. Conclusion: An undetected JPA can have the same audiological clinical presentation as a unilateral ANSD. This case description highlights the need to heighten awareness for neurological and radiological monitoring in cases of ANSD, especially when the presentation is unilateral.

Another purpose was to determine the benefits of personal FM systems. Design: The study is a randomized control trial where participants were allocated to groups receiving one of the two interventions, with and without personal FM, or to the no intervention group. The six-week intervention included weekly one-hour sessions with a therapist in the clinic, plus 1-2 hours per week of parent-directed homework. Study sample : 55 children (7 to 13 years) with APD participated in the study. Intervention outcomes included reading, language, and auditory processing. Results: Positive outcomes were observed for both training approaches and personal FM systems on several measures. Pre-intervention nonverbal IQ, age, and severity of APD did not influence outcomes. Performance of control group participants did not change when retested after the intervention period. Conclusions: Both intervention approaches were beneficial and there were additional benefits with the use of personal FM. Positive results were not limited to the areas specifically targeted by the interventions. C1 [Sharma, Mridula; Purdy, Suzanne C.] Macquarie Univ, Dept Linguist Audiol, Sydney, NSW 2109, Australia.

Design: A cohort that had received a universal neonatal hearing screen was followed-up until school entry, and confirmation of deafness compared with that from parallel cohorts that had not received the screen. Study: Three 10-year cohorts were compared: a cohort of 35 668 enrolled for universal neonatal hearing screening, a historical cohort of 31 538 when neonatal screening was unavailable, and a cohort of 32 890 when targeted screening was in place. Results: Prevalence of deafness by school age was 3.65/1000 with a neonatal yield of 1.79/1000. The screen had been 89% sensitive to moderate and worse deafness, 79% to unilateral deafness, and 49% to mild impairments. The median age of confirmation had been reduced from 218 to 16 weeks, but for those not identified neonatally there had been no significant improvement in the age of confirmation over the previous 25 years. The yield from post-neonatal screens had been reduced from 1.8/1000 to 0.2/1000, and with a yield of 0.8/1000, reactive referral remained a more effective route to identification. Conclusions: Even with UNHS in place post-neonatal routes to identification need to be maintained and improvements investigated.

Design: The masked threshold of noise bands (250-8000 Hz), continuous discourse, and the amount of masking produced were determined. The maximal vocalization level was determined, that still allowed the subject to just follow the continuous discourse. Study sample: Twenty persons with sensory-neural HI, twelve with a high-frequency (HF) loss and eight with low-, mid-frequency or flat (LMF) loss. Results: The [a:] gave a significantly higher masked threshold at 70 and 80 dBA vocalization for subjects with HF loss than for normal-hearing (NH) subjects, and somewhat higher thresholds than for those with LMF loss. The amount of masking produced was significantly smaller for subjects with HI than NH. Conclusions: It is important to consider masking effects of self-produced sounds in auditory rehabilitation, and in the future design of hearing aids.

Castro, Franz Zenker Wardenga, Nina Kollmeier, Birger TI A Spanish matrix sentence test for assessing speech reception thresholds in noise SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech recognition; speech reception threshold (SRT); Spanish sentence test in noise; matrix test ID INTELLIGIBILITY; HEARING AB Objective: To develop, optimize, and evaluate a new Spanish sentence test in noise. Design: The test comprises a basic matrix of ten names, verbs, numerals, nouns, and adjectives. From this matrix, test lists of ten sentences with an equal syntactical structure can be formed at random, with each list containing the whole speech material. The speech material represents the phoneme distribution of the Spanish language. The test was optimized for measuring speech reception thresholds (SRTs) in noise by adjusting the presentation levels of the individual words. Subsequently, the test was evaluated by independent measurements investigating the training effects, the comparability of test lists, open-set vs. closed-set test format, and performance of listeners of different Spanish varieties. Study sample: In total, 68 normal-hearing native Spanish-speaking listeners. Results: SRTs measured using an adaptive procedure were 6.2 +/- 0.8 dB SNR for the open-set and 7.2 +/- 0.7 dB SNR for the closed-set test format. The residual training effect was less than 1 dB after using two double-lists before data collection. Conclusions: No significant differences were found for listeners of different Spanish varieties indicating that the test is applicable to Spanish as well as Latin American listeners. Test lists can be used interchangeably. C1 [Hochmuth, Sabine; Brand, Thomas; Zokoll, Melanie A.; Kollmeier, Birger] Carl von Ossietzky Univ Oldenburg, Inst Phys, D-26129 Oldenburg, Germany.

Design: The study had a cross-sectional design in which participants were asked to fill in written questionnaires. Study sample: The sample consisted of 119 individuals with moderate to profound AHL, acquired in adulthood. Symptoms of depression and anxiety, cognitive coping strategies, and goal-related coping processes were assessed. Results: Relationships between these variables were statistically tested by Pearson correlations and multiple regression analyses. The results showed that ruminative and catastrophizing ways of coping were related to the reporting of more symptoms of depression and/or anxiety. In contrast, refocusing attention to more pleasant issues, disengaging from unattainable goals, and re-engaging in alternative, meaningful goals were related to the reporting of less symptomatology. Conclusions: These results provide us with important targets for prevention and intervention of mental health problems in people with AHL.

Design: Prospective study. Study Sample: Fourteen healthy subjects underwent oVEMP tests combined with real-time triaxial accelerometry. Results: Under BV stimulation from a vibrator to the Fz and Fpz sites, acceleration magnitudes along x-, y- or z-axis did not significantly differ between the two sites. The mean nI and pI latencies of the oVEMPs stimulated at Fz were significantly earlier than those at Fpz. However, no statistical differences existed in the nI-pI interval and amplitude between the two sites. A blunt or double peak nI configuration was noted in three subjects (22%) when tapping at Fpz, but not at Fz, likely because different muscles contributing to the oVEMPs. Conclusion: While both Fz and Fpz are effective sites for generating an oVEMP, the variation in human skull shapes and properties will lead to different acceleration profiles being transmitted to the vestibular apparatus. These differing stimuli may lead to different oVEMP profiles, so if one site does not produce the expected response, the clinician should try the other site.

The aim of this study was to assess the repeatability of the ANL measured in normal-hearing subjects using running Danish and non-semantic speech materials as stimuli and modulated speech-spectrum and multi-talker babble noises as competing stimuli. Design: ANL was measured in both ears at two test sessions separated by a period ranging from 12 to 77 days. At each session the measurements at the first and the second ear were separated in time by 15-30 minutes. Bland-Altman plots and calculation of the coefficient of repeatability (CR) were used to estimate the repeatability. Study sample: Thirty nine normal-hearing subjects. Results: The ANL CR was 6.0-8.9 dB for repeated tests separated by about 15-30 minutes and 7.2-10.2 dB for repeated tests separated by 12 days or more. Conclusions: The ANL test has poor repeatability when assessed with Danish and non-semantic speech materials on normal-hearing subjects. The same CR among hearing-impaired subjects would imply too poor repeatability to predict individual patterns of future hearing-aid use.

Design: Twenty-eight otologically normal test subjects participated in the ETSPL determination for the Etymotic Research ER-10C probe. Study sample: ETSPLs were determined up to 16 kHz and were compared to the reference hearing thresholds associated with the ER-3A insert earphone. Both 'regular' and 'baby' foam eartips were used. Results: At most frequencies, no significant threshold differences were observed between the insert earphone and the DPOAE probe. However, at 1 kHz and 4 kHz, the mean thresholds for the insert earphone were generally lower than those for the DPOAE probe, suggesting systematic differences at those frequencies. Repeated calibration runs resulted in deviations of about 0.6 dB. Similar deviations were noticed when using foam eartips of different sizes up to 10 kHz. Conclusions: Knowing the reference thresholds for DPOAE probes enables measurements of (subjective) hearing thresholds and (objective) otoacoustic emissions using the same probe. Probe fitting and eartip size had negligible effect on the determination of ETSPLs. The obtained data may be proposed for inclusion in future audiometry standards.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Classroom; Noise; Speech discrimination score; Unilateral hearing loss ID REVERBERATION TIME; SPEECH-INTELLIGIBILITY; CHILDREN; AMPLIFICATION; PERFORMANCE; IMPAIRMENT; PREVALENCE AB Objective: To determine the optimal seating position in a noisy classroom for students with unilateral hearing loss (UHL) without any auditory rehabilitation as compared to normal-hearing adults and student peers. Design: Speech discrimination scores (SDS) for babble noise at distances of 3, 4, 6, 8, and 10 m from a speaker were measured in a simulated classroom measuring 300 m 3 (reverberation time = 0.43 s). Study Sample: Students with UHL (n = 25, 10-19 years old), normal-hearing students (n = 25), and normal-hearing adults (n = 25). Results: The SDS for the normal-hearing adults at the 3, 4, 6, 8, and 10 m distances were 90.0 +/- 6.4%, 84.7 +/- 7.9%, 80.6 +/- 10.0%, 75.5 +/- 12.6%, and 68.8 +/- 13.0%, respectively. Those for the normal-hearing students were 90.1 +/- 6.2%, 78.1 +/- 9.4%, 66.4 +/- 10.7%, 61.8 +/- 11.2%, and 60.8 +/- 10.9%. Those for the UHL group were 81.7 +/- 9.0%, 70.2 +/- 12.4%, 62.1 +/- 17.2%, 52.4 +/- 17.1%, and 48.9 +/- 17.9%. The UHL group needed a seating position of 4.35 m to achieve an equivalent mean SDS as those for normal-hearing adults seated at 10 m. Likewise, the UHL group needed to be seated at 6.27 m to have an equivalent SDS as the normal-hearing students seated at 10 m. Conclusions: Students with UHL in noisy classrooms require seating ranging from 4.35 m to no further than 6.27 m away from a teacher to obtain a SDS comparable to normal hearing adults and student peers.

Design: A cross-sectional survey with population-based controls. Study sample: Forty-five patients, with sensorineural or mixed HI and an available blood sample for GJB2 sequencing from DNA, were selected from 166 East Greenlanders by specialist audiology examination, including pure-tone air and bone conduction audiometry from 125 Hz to 8000 Hz. Controls were 108 East- and 109 West-Greenlanders. Results: Forty-five patients with HI were included, 24 males and 21 females. Median age was 35 years (range: 5-76). The c.35delG allele frequency was 3.3%. One patient, homozygous for the c.35delG GJB2 mutation, had bilateral congenital profound HI. Another with mixed HI was heterozygous for the same mutation. Three were heterozygous for the p.V27I variant and one was heterozygous for the p.V153I variant. The frequency of the c.35delG mutation in the controls varied between 0.5% in West Greenland to 2.3% in East Greenland. Conclusion: The c. 35delG GJB2 mutation occurs in Greenland with low frequency. We conclude the main causes behind the prevalence of HI in this population are chronic otitis media, noise traumas, and/or unidentified genetic causes.

Design: Sentence stimuli corrupted by reverberation, noise, and reverberation + noise are presented to 11 CI listeners for word identification. They are tested in two reverberation conditions (T-60 = 0.6 s, 0.8 s), two noise conditions (SNR = 5 dB, 10 dB), and four reverberation + noise conditions. Study sample: Eleven CI users participated. Results: Results indicated that reverberation degrades speech intelligibility to a greater extent than additive noise (speech-shaped noise), at least for the SNR levels tested. The combined effects were greater than those introduced by either reverberation or noise alone. Conclusions: The effect of reverberation on speech intelligibility by CI users was found to be larger than that by noise. The results from the present study highlight the importance of testing CI users in reverberant conditions, since testing in noise-alone conditions might underestimate the difficulties they experience in their daily lives where reverberation and noise often coexist.

Design: Participants wore personal noise exposure meters for up to five days. During this time, participants kept diaries of daily events and estimated the loudness of these events and their overall noise exposure using 1-to-10 rating scales. Study sample: A group of 45 volunteers aged between 18 and 35 years participated in the study. Results: 86% of participants' subjective estimates were significantly correlated with the objective noise measurements. Multiple regression showed that age, overall lifestyle noise, and diary quality were predictors of the strength of correlation observed. In addition participants' subjective estimates of their overall noise exposure were significantly correlated with their actual average daily noise exposure. Conclusions: Results suggest that individuals can make a reasonable estimate of the loudness of events they experience and the overall level of noise they experience. These results may have significant influence for those interested in producing effective hearing health awareness programs in that individuals may be capable of assessing their own degree of hazard exposure.

Design: Cross-sectional survey. Study sample: One hundred and twenty-five experienced hearing-aid users. Methods: The subjects completed a history form seeking demographic data and a questionnaire combining the SADL-CH instrument with questions seeking subjects' subjective ratings of satisfaction with some hearing-aid features and overall satisfaction with their hearing aid. Results: The SADL-CH questionnaire had a good internal consistency reliability estimate (alpha = 0.79) comparable to that of the original version. SADL-CH scores were observed to have significant correlations with other satisfaction ratings on some hearing-aid features and the overall satisfaction measure. A high degree of test-retest reliability (intraclass correlation coefficient = 0.79) was observed. Confirmatory factor analysis revealed that the SADL-CH questionnaire had a four-factor structure. Interim norms were derived for the SADL-CH questionnaire. The level of hearing-aid satisfaction in Chinese adults was generally lower than that reported in studies conducted among Western populations. Conclusion: The SADL-CH questionnaire is a reliable and valid instrument for measuring hearing-aid satisfaction.

TI Agreement between psychophysical tuning curves and the threshold equalizing noise test in dead region identification SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Psychoacoustics/hearing science; anatomy and physiology; medical audiology; noise ID FREQUENCY HEARING-LOSS; COMBINATION TONES; PURE-TONE; BASILAR-MEMBRANE; MASKING; LEVEL; DIAGNOSIS; COCHLEA; INTELLIGIBILITY; PERCEPTION AB Objective: Identification of dead regions is currently based on the results of psychophysical tuning curves (PTC) and the threshold equalizing noise (TEN) test. Summers et al (2003) found poor agreement (56%) between PTC- and TEN test results. Kluk and Moore (2005) argued that these results are explained by beat- and/or combination tone detection. The purpose of this study was to examine the diagnostic dead region relationship between PTCs, modified for beats and/or combination tone detection, and the TEN test with levels calibrated in hearing levels (HL), i.e. TEN[HL]. Design: Twenty-four hearing-impaired ears were evaluated using PTCs and the TEN[HL] test. Results: The results show an agreement of about 75%, depending on the criteria applied, between PTC and the TEN[HL] test. Results also show that PTC probe levels affected diagnostic results in PTCs. Conclusions: Recommended criteria based on the highest agreement score included a PTC shift of 20% and an 8-dB probe elevation above TEN masking levels for the TEN[HL] test. Low agreement scores and level dependent effects in PTCs and the TEN[HL] test suggest that identification of dead regions using a single test is not reliable.

Design: SOE was measured using the forward masking technique (selectivity), as well as with a "fixed stimulus, variable recording" (scanning) technique. SOE profiles were produced at three current levels and at three sites along the array. Additionally, effects of the position of the recording electrodes and artefact rejection methods were studied in five subjects. Furthermore, correlation between SOE data and speech perception data was tested. All data were analysed using linear mixed models. Study sample: Measurements were performed intraoperatively in 31 users of the Advanced Bionics HiRes 90K cochlear implant. Results: The selectivity method produced narrower excitation profiles than the scanning method, showing an asymmetry along the array with wider SOE apically. Moreover, the position of the recording electrode shifted the SOE curves towards the recording contact, enhancing asymmetry. Neither significant effects of current level or artefact rejection methods were observed, nor a significant correlation with speech perception. Conclusions : SOE profiles obtained with the scanning method are wider than with the selectivity method. Both are insensitive to various parameter settings, although selectivity curves are shifted towards the recording contact. C1 [van der Beek, Feddo B.; Briaire, Jeroen J.; Frijns, Johan H.

Design: A cross-sectional study to compare HFT results obtained from neonates in two head positions (face sideways and face up). Study sample: One hundred and fifty-seven neonates (80 female, 77 male; mean age = 48.3 +/- 26.7 hours) participated. Results: The mean uncompensated admittance at 200 daPa obtained in the face sideways position was significantly greater than that obtained in the face up position (1.02 versus 0.96 mmho). A significant ear effect for baseline compensated admittance was found (right/left = 0.64/0.53 mmho). However, there were no significant main effects for head positions for the tympanometric peak pressure, baseline compensated static admittance, and component compensated static admittance measures, indicating that these measures are resilient to head positions. Conclusion: These findings support the use of HFT normative values regardless of the two head positions investigated in the present study.

Robert TI Steady-state analysis of auditory evoked potentials over a wide range of stimulus repetition rates: Profile in children vs. adults SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory evoked potentials; auditory steady-state responses; total harmonic distortion; harmonic sum ID MODULATION FOLLOWING RESPONSE; EVENT-RELATED POTENTIALS; AMPLITUDE-MODULATION; YOUNG-CHILDREN; THRESHOLD ESTIMATION; FREQUENCY; INFANTS; PHASE; AMFR; ASSR AB Objective: Auditory steady-state responses (ASSR) evoked by recurrent brief tones were assessed over a wide range of stimulus repetition rates apropos the traditionally measured obligatory, transient, auditory evoked potentials. Repetition rates of <= 10 Hz have received little attention in the context of the ASSR stimulus-response analysis approach, speculated to provide technical advantages/additional information over more traditional transient stimulus-response paradigms. Design : Magnitudes were measured at repetition rates from 0.75 to 80 Hz, using trains of repeated tone-burst stimuli. Study sample : Twelve normal-hearing children and a reference sample of 25 young adults. Results : Results show that response magnitudes were significantly larger in children than adults at repetition rates of <= 5 Hz. Magnitudes were largest at the two lowest repetition rates, following the trends expected from the transient auditory evoked potential (AEP) literature. The harmonic sum is proposed as a more appropriate measure of response magnitude than amplitude of the fundamental alone. Conclusions : The analysis methods used in this paper may give information that will have applications for clinical testing. Of pragmatic importance is that the stimulus rate profile could be determined without subjective wave identification and/or interpretation, and thus by a method that is inherently more objective than conventional AEP analysis.

TI Auditory skills, language development, and adaptive behavior of children with cochlear implants and additional disabilities SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implant; pediatric ID DEAF-CHILDREN; HANDICAPPED-CHILDREN; SPEECH; ATTENTION; OUTCOMES; AGE AB Objective: The objective of this study was to evaluate the development of functional auditory skills, language, and adaptive behavior in deaf children with cochlear implants (CI) who also have additional disabilities (AD). Design: A two-group, pre-test versus post-test design was used. Study sample: Comparisons were made between 23 children with CIs and ADs, and an age-matched comparison group of 23 children with CIs without ADs (No-AD). Assessments were obtained pre-CI and within 12 months post-CI. Results: All but two deaf children with ADs improved in auditory skills using the IT-MAIS. Most deaf children in the AD group made progress in receptive but not expressive language using the Preschool Language Scale, but their language quotients were lower than the No-AD group. Five of eight children with ADs made progress in daily living skills and socialization skills; two made progress in motor skills. Children with ADs who did not make progress in language, did show progress in adaptive behavior. Conclusions: Children with deafness and ADs made progress in functional auditory skills, receptive language, and adaptive behavior. Expanded assessment that includes adaptive functioning and multi-center collaboration is recommended to best determine benefits of implantation in areas of expected growth in this clinical population.

The purpose of this study was to investigate the sound pressure level (SPL) at head positions likely to be encountered in routine audiological practice. Design: Eight National Health Service SF clinics were used to obtain SPL measurements. Part 1 of the study investigated SPL variability at positions around the CP (0.15 m and 0.30 m). Parts 2 and 3 of the study, investigated the SPL at two typical head heights of the infant population. Study sample: Only sound field measures were obtained. Results: Part 1: 32% and 40% of measurements of SPL around the CP were > 2 dB different from the SPL at the CP (0.15 m and 0.30 m). Parts 2 and 3: 55% and 38% of measurements of SPL, at the two infant head heights, were > 2 dB from the SPL at the CP. Conclusions: Variability in SPL, due to head movement, is to be expected when performing SF audiometry. Furthermore, the typical head heights of infants will introduce additional variability, unless the position of the CP is chosen carefully.

Design: Baseline and 17-months follow-up hearing status was examined with pure-tone audiometry, TEOAEs, and DPOAEs. Study sample : A total of 233 noise-exposed employees were measured, while 60 subjects from this group contributed to test-retest reliability measures. Results: Group-averaged changes and individual shifts followed similar patterns: decreases for audiometry at 6-8 kHz and DPOAE at 1.5 kHz, and enhancements for DPOAE at 3 kHz. TEOAEs showed an overall deterioration while both individual deteriorations and enhancements were larger than chance. DPOAE at 6 kHz showed the largest group-averaged change, while the number of individual shifts was not significant. There were no clear relations between changes in audiometry and changes in OAE. Conclusion: Significant individual OAE changes do not necessarily follow the same pattern as the group-averaged results. This limits the applicability of OAE testing for the monitoring of individual subjects. Furthermore, hearing deterioration might manifest itself in a local enhancement of otoacoustic emissions and not only in the form of decreases in amplitude.

Study sample: Sixty-two patients with Meniere's disease. Design: Retrospective study. Results: Out of 62 patients 65% received one injection, 24% two, 6% three, 3% five, and 2% six injections. Between injections, class A vertigo control was obtained after two weeks in all cases. Before ITPG, out of 62 pure-tone threshold audiograms 37 were 'flat'. Average hearing threshold at 2 kHz was significantly better than that of 250, 500, and 0.75 kHz on the affected side. Conclusions: Hearing threshold in advanced MD is often flat with a characteristic small peak in the high frequency range, most frequently around 2-3 kHz.

TI Evaluation of patients with vertigo of vertebrobasilar insufficiency origin using auditory brainstem response, electronystagmography, and transcranial Doppler SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Vertigo; vertebrobasilar insufficiency (VBI); electronystagmography (ENG); transcranial Doppler (TCD); auditory brainstem response (ABR); pulsatility index (PI); mean flow velocity (MFV); posterior inferior cerebellar artery (PICA) ID ANGIOGRAPHIC FINDINGS; VASCULAR-DISEASE; BLOOD-FLOW; ISCHEMIA; STROKE; SONOGRAPHY; DIAGNOSIS; STENOSIS; DEAFNESS; MRI AB Objectives: Vertigo can be a manifestation of underlying vertebrobasilar stroke in older adults. The study objectives were to investigate the correlation, sensitivity, and specificity of the auditory brainstem response (ABR), electronystagmorgraphy (ENG), and transcranial Doppler (TCD) collectively to distinguish between vertigo due to vertebrobasilar insufficiency (VBI) and vertigo due to non-VBI. Design: Prospective experimental study comparing ENG, ABR, and TCD battery findings between two groups of patients with vertigo and a control group. Study sample: Participants included 14 patients with vertigo of VBI origin, 14 patients with vertigo of non-VBI, and 11 matched controls. Results: Participants with VBI had more abnormal findings in the ENG (86%), TCD (72%), and ABR (64%) compared to the non-VBI group (64%, 21%, and 7%, respectively) and the control group. The combined battery revealed positive correlations, 64% sensitivity, and 84% positive predictive value (PPV) in the VBI group, and 100% specificity with lack of correlations in the non-VBI group. Conclusions: The modest sensitivity and PPV helps with early detection of VBI, thus preventing risk of vertebrobasilar stroke in 84% to 64% of patients. The 100% specificity in the non-VBI group rules out VBI, thus reducing the referral rate for unnecessary, diagnostic evaluations and ineffective treatment.

Study sample: Nine CI users with contralateral residual acoustic hearing. Design: Absolute acoustic thresholds in the unimplanted ear were measured and frequency selectivity was assessed via psychophysical tuning curves. An adjustment method was used to match the percepts elicited by pulse trains on individual electrodes with various acoustic signals (pure tones, narrow-band noises, and bandpass filtered pulse trains). The starting frequency of the acoustic signal was roved and matches were obtained at different loudness levels. Results: Acoustic frequency selectivity varied widely. Two subjects showed clear evidence of frequency selectivity extending above 500 Hz. Only these subjects produced consistent pitch matches over repeated measurements. For other subjects, the acoustic frequency eventually selected tended to correlate with the initially presented frequency. There was limited evidence of level effects and these were inconsistent across subjects and electrodes. Conclusions: Across-modality pitch/timbre matching appears unlikely to provide a generally applicable method for determining the effective characteristic frequencies of cochlear implant electrodes. Frequency selectivity above 500 Hz may be necessary for consistent pitch/timbre matches. C1 [Green, Tim; Faulkner, Andrew; Rosen, Stuart] UCL, London WC1N 1PF, England.

Two experiments were conducted with specific aims of (1) developing sentence material that is grammatically and semantically within the linguistic abilities of children; and (2) improving the efficiency of the test by equalizing the relative intelligibility of individual items in sentences. Design and Study sample: Sentences were extracted from spoken material of Chinese children aged between 4 and 5 years of age. The sentences were tested for intelligibility in a four-talker babble by 96 adult native speakers of Mandarin. Psychometric functions were generated, and used for adjusting signal-to-noise ratios of individual items by varying the level of the time-locked babble to equate intelligibility of the target speech. These adjusted stimuli were tested for intelligibility using a different group of 64 adult listeners. Results: The signal-to-noise ratio for 50% correct was not different before and after adjustments (-6.1 dB and -6.0 dB, respectively). However, there was a significant reduction in standard deviation from 2.3 dB before adjustment to 1.1 dB after adjustment (p < 0.05). Conclusions: The experiments established a corpus of Mandarin BKB-like sentences with four-talker babble as competing noise, in which the test items' homogeneity was optimized via psychometric evaluation (HOPE).

A relative amplitude difference is defined in the present paper as the difference in Na-Pa amplitude between two electrodes (e.g. vertical bar Na-Pa at C3 minus Na-Pa at C4 vertical bar, or electrode effects) or between two ears (e.g. vertical bar Na-Pa on left ear stimulation minus Na-Pa on right ear stimulation vertical bar, or ear effects). In contrast, an absolute amplitude is defined as a single Na-Pa measurement made at one electrode for stimulation of one ear (e.g. Na-Pa measured at C3 on left ear stimulation). Design: Cross-sectional study. Study sample: 155 pediatrics with normal peripheral and central hearing, and no history of psychological, neurological, or learning disability issues. Results: Within-group variability was significantly smaller for relative differences when compared to absolute amplitude measures. Electrode effects showed significantly less variability than ear effects. Normative values for ear and electrode effects were reported. Conclusions: Relative differences may provide better utility in the clinical diagnosis of central auditory pathology in pediatrics when compared to absolute amplitude measures because these difference measures show significantly lower variability when examined across subjects.

Design: Independent component analyses were performed to evaluate coherent spontaneous activity in distributed brain networks. The resting-state functional connectivity scores between the right and left auditory networks were measured. Direct comparison of resting-state connectivity between tinnitus patients and controls was made using a two-sample t-test. Study sample: Four patients (three male, one female; mean age 45 +/- 3.92 years) with chronic tinnitus lateralized to the left ear, and six age-matched controls (four male, two female; mean age 45 +/- 2.76 years) participated in this case study. Results: The average resting-state functional connectivity (FC) score between the left and right auditory cortical regions was significantly lower in tinnitus patients than in controls (P < 0.05). Direct comparison between patients and controls showed that increased functional connectivity caused by tinnitus occurred predominantly in the left amygdala and in the dorsomedial prefrontal cortex. Conclusions: Our pilot study suggested that resting state functional magnetic resonance imaging (fMRI) could be useful to investigate possible alterations in resting-state neuronal activity between the auditory and non-auditory networks in tinnitus patients.

Robert TI Steady-state analysis of auditory evoked potentials over a wide range of stimulus repetition rates in awake vs. natural sleep SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory evoked potentials; auditory steady-state responses; total harmonic distortion; harmonic sum; sleep ID MODULATION FOLLOWING RESPONSE; MIDDLE LATENCY; FREQUENCY; ONSET AB Objective : Auditory steady-state responses (ASSR) evoked by recurrent tones were assessed over a wide range of stimulus repetition rates embracing well the traditionally measured transient AEPs. Repetition rates of <= 10 Hz have received little attention in the context of the ASSR stimulus-response analysis approach which is speculated to provide technical advantages, if not additional/supplemental information, over more traditional transient stimulus-response paradigms. Design: Magnitudes were measured at repetition rates from 0.75 to 80 Hz, using trains of recurrent tone-burst stimuli. Study sample: Twenty-five normal-hearing adults during sleep and awake. Results: Results show that response magnitudes for adults tested during sleep were significantly larger than those for adults while awake at repetition rates < 5 Hz. Magnitudes were largest at the two lowest repetition rates, as expected from corresponding results obtained using conventional methods. Conclusions: The analysis methods used in this paper may give information that will have applications for clinical testing. Results confirm and extend knowledge of the effects of repetition rate on AEPs over a range embracing the gamut of responses as traditionally classified, specifically at the beginning stages of natural sleep.

Design: Prospective study. Study sample: 180 consecutive children aged 2 to 5 years, referred for language retardation and/or behavioral problems, who could not be tested by behavioral methods, underwent ABR and ASSR recordings. The children who did not spontaneously nap were sedated by intrarectal pentobarbital eventually potentiated by oral alimemazine. Results: A spontaneous nap was obtained in only 23 cases, 72 children received only pentobarbital, and 85 received both pentobarbital and alimemazine. Even so, recording was impossible in 16 cases, and interrupted before completion of the ASSR recordings in 45 cases. Children went to sleep in average 64 min +/- 40. The average recording time for the ABR was 20 minutes, and for the ASSR 25 minutes. Conclusion: Sedation by pentobarbital, eventually completed by oral alimemazine, allows ABR and/or ASSR recordings in 89.8% of the children who did not nap in the recording room, and is therefore a good alternative to general anesthesia in these children.

Design: The study included two parts: (1) A self-report questionnaire on music listening habits, and (2) Physical measurements of preferred listening levels, in quiet and in everyday background noise. Study sample: Young teenagers aged 13 to 17 years. Part 1 included 289 participants with mean age of 14 years. Part 2 included 11 and 74 participants (2A and 2B) with a mean age of 15 years. Eleven listened to PLDs in quiet conditions (2A) and 74 in everyday background noise (2B). Results: Questionnaire main findings indicated that most of the participants reported high or very high volume settings and demonstrated low awareness towards loud music listening consequences. Physical measurements corrected for diffuse field indicated mean preferred listening levels of: 82 (SD = 9) dBA in quiet, and 89 (SD = 9) dBA in the presence of background noise. The potential risk to hearing of PLDs users was calculated using the 8 hour equivalent level. Conclusion: More than 25% of the participants in the noisy condition were found to be at risk according to occupational damage risk criteria (NIOSH, 1998).

TI Comparison of self-reported and audiometrically-measured hearing loss in the Australian Defence Force SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing loss; Audiometry; Self-report; Military; Sensitivity; Specificity ID NOISE EXPOSURE; ACCURACY; POPULATION; WORKING; COHORT AB Objective: To investigate the relationship between self-reported and audiometrically-measured hearing loss in a sample of Australian Defence Force personnel. Design: Responses to a question regarding hearing problems were compared with contemporaneous audiometric data. Study sample: 3335 members of the Australian Defence Force for whom anonymised medical records were available. Results: The sensitivity of self-report data to identify higher-frequency hearing loss was lower than sensitivity at other frequencies, and positive predictive values were moderate to poor at all frequencies. Performance characteristics of self-report compared with audiometric data also varied with age, sex, and rank. Conclusions: While self-report hearing loss data have good performance characteristics for estimating prevalence of hearing loss as defined by audiometric criteria, this study indicates that the usefulness of self-report data in identifying individuals with hearing loss may be limited in this population.

Design: The ANL test was applied to three NRAs. Furthermore, the measured Delta ANL was predicted using several methods based on either the calculation of the signal-to-noise ratio or correlation methods of the processed signals with an unprocessed reference signal. Study sample: Ten normal-hearing and eleven hearing-impaired subjects accomplished the ANL test. Results: In general, the ANL test could determine an increased acceptance of noise with some NRAs. However, great inter-individual differences also resulted that were attributed to audible distortions when an NRA was used. Prediction of the mean measured Delta ANL was possible, but individual prediction of Delta ANL failed due to inter-individual differences. Mean Delta ANL was predicted more accurately for hearing-impaired subjects when individual hearing loss was taken into account. Conclusions: The ANL test is a suitable tool for measuring the advantage of one NRA. A prediction of the measured individual Delta ANL failed. However, mean Delta ANL could be predicted with some methods. Furthermore, the individual hearing loss should be taken into account for a more accurate prediction for hearing-impaired subjects.

Design : EFRs were recorded in animals at different postnatal ages (15, 20, 25, 35, and 70 postnatal days) in response to broadband noise (BBN) and tones of 8000 and 4000 Hz modulated in amplitude using a continuous sweep of modulation frequencies. Responses were analysed in the 90-190 Hz modulation frequency (MF) range. Study sample: Forty individuals (eight individuals for each age bracket) were included in the present study. Results: During maturation, the MF at which the maximum amplitude was obtained (BMF, best modulation frequency) shifted to higher values when animals were stimulated with tones. At the same time, the amplitude of the response at the BMF increased. For every group of animals, the amplitude of the response continuously decreased for MFs higher than the BMF. However, less steep decreases of amplitude were obtained as animals became adults. Conclusions: These results provide normative data regarding the maturation of the EFR in rats. They provide information for the development of predictor models to estimate the temporal resolution of the auditory system during maturation.

Design: Fast-PTCs with swept-noise (SN) and gated-noise (GN) maskers were measured at signal frequencies of 500, 1000, 2000, and 4000 Hz. The effect of amplitude modulating the signal in the GN condition was evaluated. Two PTC runs were obtained for each condition to assess training effects. Study sample: Eight normally-hearing young adults participated in the study. Results: The SN and GN methods resulted in similar estimates of frequency selectivity when training effects were considered. Amplitude modulating the tone in the GN method reduced the effect of training. On average, SN-PTCs were most repeatable compared to the two other methods and they were not affected by training. Estimation of the shift in the PTC tip frequency was not affected by the measurement method or training effects. Fast-PTC methods resulted in similar estimates of tuning as compared to published notched-noise data. Conclusions: The SN method and the GN procedure with amplitude modulated signals allowed for time-efficient estimation of frequency selectivity that was unaffected by training.

Objective : The purpose of the present study was to adapt the PEACH scale into the Malay language, and to collect normative data on a group of children with normal hearing. Study sample: The participants were parents of 74 children aged between 3 months and 13 years of age. Parents were requested to observe their children's auditory/oral behavior in everyday life and to record their observations in the PEACH booklet. Results: High internal consistency (Cronbach's alpha = 0.93) and item-total correlation were found (0.52-0.85). Similar to the published norms for English-speaking children, near-perfect scores were achieved by Malaysian children around 40 months of age. Conclusions: The adapted version can be used to evaluate amplification for children in the Malay speaking environment. The normative curve relating age to scores for the Malay PEACH can be used as a reference against which functional aural/oral performance of hearing-impaired Malaysian children can be evaluated.

TI Binaural dichotic presentation to reduce the effects of spectral masking in moderate bilateral sensorineural hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Binaural hearing; comb filters; dichotic presentation; sensorineural hearing loss; spectral masking; spectral splitting ID SOUND LOCALIZATION; IMPAIRED LISTENERS; HIGH-FREQUENCIES; RESPONSE-TIMES; SPEECH; INTELLIGIBILITY; NOISE; MODELS; ENHANCEMENT; BANDS AB Objective: The objective of the study was to evaluate the effectiveness of binaural dichotic presentation using comb filters with complementary magnitude responses, based on fixed bandwidth and auditory critical bandwidth, in improving speech perception by persons with moderate bilateral sensorineural hearing loss, and to assess its effect on localization of the sound source. Design and Study sample: Listening tests involving consonant recognition and source direction identification were conducted on six normal-hearing subjects under simulated hearing loss and on eleven subjects with moderate bilateral sensorineural loss in quiet. Results: The tests on normal-hearing subjects showed higher recognition scores and smaller response times for the comb filters based on the auditory critical bandwidth. The tests using these comb filters on the hearing-impaired subjects resulted in an increase of 14%-31% (mean: 22%) in recognition scores and a significant decrease in response times, with no significant effect on the identification of the direction of broadband sound sources. Conclusions: The results show that dichotic presentation may be useful for speech processing in binaural hearing aids.

TI DPOAEs and contralateral acoustic stimulation and their link to sound hypersensitivity in children with autism SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Autism; contralateral suppression; distortion-product otoacoustic emissions; hypersensitivity; outer hair cells ID PRODUCT OTOACOUSTIC EMISSIONS; COCHLEAR MICROMECHANICAL PROPERTIES; INFANTILE-AUTISM; DISTORTION PRODUCTS; HEARING-LOSS; BRAIN; HUMANS; SUPPRESSION; DYSFUNCTION; ALTERS AB Objective: The hypersensitivity of children with autism to sound is a relatively unexplained behavior. The goal of the current study was to investigate the DPOAE characteristics of children with autism compared to a control group. Design : DPOAEs with and without contralateral stimuli were measured in two groups in three different conditions. Study sample : The study employed 14 children with autism and a control group with 28 age-matched participants. Results : In the without-contralateral stimulus condition, the overall S/N of DPOAEs was greater for the control group compared to the autism group (p < 0.0005). For both groups, the DPOAE S/N increased as a function of frequency in both ears. In the with contralateral stimulus condition, group and ear effects were noticed, however, no age, frequency, or contralateral stimulus type (BBN vs. 1000 Hz) effect could be detected. Conclusions: Presence of reduced DPOAEs in the autism group does not support the hypothesis that sound hypersensitivity in children with autism may be related to overactive outer hair cells function; rather it may be due to early cochlear dysfunction. Also, sound hypersensitivity in the autism group may be due to abnormality of the efferent auditory pathway as shown by lack of sufficient contralateral suppression.

No specific listener characteristics have been identified as being related to a listener's ability to accept background noise. The purpose of this study was to determine whether or not locus of control and self-control are related to ANL. Design: Correlational design. Study sample: Participants were seventy young adults (21 male, 49 female; aged 19 to 39 years) with normal hearing. Participants completed psychological profiles that evaluated locus of control and self-control and their ANLs were measured. Results: Results revealed correlations between ANL and self-control. Listeners with higher levels of self-control accepted more background noise than listeners with lower levels of self-control. Conclusions: This research suggests that exercises aimed at strengthening a listener's auditory self-control may lead to improved background noise acceptance. Improvement in background noise acceptance could lead to improved hearing-aid success. Future research should explore these possibilities.

The aim of the present study was to generate Danish, Swedish, and a non-semantic version of the ANL test and investigate normal-hearing Danish and Swedish subjects' performance on these tests. Design: ANL was measured using Danish and Swedish running speech with two different noises: Speech-weighted amplitude-modulated noise, and multi-talker speech babble. ANL was also measured using the non-semantic international speech test signal (ISTS) as speech signal together with the speech-weighted amplitude-modulated noise. The latter condition was identical in both populations. Study sample: Forty Danish and 40 Swedish normal-hearing subjects. Results: In both populations ANL results were similar to previously reported results from American studies. Generally, significant differences were seen between test conditions using different types of noise within ears in each population. Significant differences were seen for ANL across populations, also when the non-semantic ISTS was used as speech signal. Conclusions: The present findings indicate that there are extrinsic factors, such as instructions, affecting the ANL results. C1 [Brannstrom, K.

A disadvantage of older German single word speech audiometric tests for children is their inapplicability in quiet and in noise. Moreover, their discrimination functions are shallower than those of optimized sentence tests, particularly in noise. The Oldenburg sentence test for children (Oldenburger Kinder-Satztest; OlKiSa) has already been shown to test reliably the speech perception in noise in normal-hearing children. Testing hearing-impaired children in noise, however, may be difficult. Therefore, quality criteria and norms for testing in quiet are also needed. Study sample : The OlKiSa in quiet was validated with 224 normal-hearing children between ages 4 to 10 years. Results: The discrimination functions are steeper (6.4 to 10.7 %/dB) than those of the commonly used German single word tests. Age-specific standards for 50% speech perception in quiet (speech reception threshold, SRT) are provided. Conclusions : The OlKiSa is a valid audiometric test to quantify speech perception in quiet in children from age 4.

Design : First, the FrMatrix was developed and normative values were obtained. Subsequently, speech reception thresholds (SRTs) for the three types of tests were gathered at four study centers representing different geographic regions in Belgium and France. Study sample: Fifty-seven normal-hearing listeners took part in the normative study of the FrMatrix, and 118 subjects, with a wide range of hearing thresholds, participated in the comparative study. Results : Homogenizing the individual words of the FrMatrix with regard to their intelligibility resulted in a reference SRT of - 6.0 (+/- 0.6) dB SNR and slope at the SRT of 14.0 %/dB. The within-subject variability was only 0.4 dB. Comparison of the three tests showed high correlations between the SRTs mutually (>0.81). The FrMatrix had the highest discriminative power, both in stationary and in fluctuating noise. For all three tests, differences across the participating study centers were small and not significant. Conclusions : The FIST, the FrMatrix, and the FrDigit3 provide similar results and reliably evaluate speech recognition performance in noise both in normal-hearing and hearing-impaired listeners.

TI Self-assessed hearing abilities in middle- and older-age adults: A stratified sampling approach SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Self-assessment; hearing ability; tinnitus; hearing-aid outcomes ID SCALE SSQ; SPEECH; QUALITIES; DISABILITY; BENEFIT; AID; ACCEPTABILITY AB Objective: For evaluation of audiological service outcomes, the primary objective was to determine baseline and target profiles on the Speech, Spatial, and Qualities of Hearing Scale (SSQ); a secondary objective was to test a short form of the SSQ; opportunity was also taken to compare responses of samples providing consistent versus inconsistent self-assessments. Design: 2 x 2 x 2 factorial design crossed age, reported presence versus absence of hearing difficulty, and low versus high self-rated hearing ability. Study sample: Eight samples (total, n = 413), representing two age ranges; a response of "yes" or "no" to a question about having hearing difficulty, and either low or high self-rated hearing ability on six items from the SSQ. Results: Using present and previous results, baseline SSQ profiles were determined indicating the pattern of response likely to be observed prior to clinical intervention, and both an achieved outcome and "ideal" target outcome from such intervention. The six-item SSQ yielded better test-retest results in consistent versus inconsistent samples. The inconsistent samples showed signs of different interpretations of "hearing difficulty". Conclusions: Baseline, and both actual and ideal target outcomes can guide comparative appraisal of clinical achievements; more research is needed to determine a robust short form of the SSQ.

Design and Study samples: Data were collected from 126 Qatari patients (58 males and 68 females) belonging to inbred families (56%), showing an autosomal recessive pattern of inheritance (96%). Fifty-three patients were less than 10 years old, 55 in the age range of 10 to 20 years, while 18 were aged between 20 and 30 years. All subjects had moderate to severe sensorineural hearing loss and were screened for GJB2 mutations, GJB6 deletion, and for A1555G mitochondrial mutation. Results: Four patients were homozygous and one was heterozygous for c. 35delG; five were homozygous for the IVS1 + 1G < A, and two were heterozygous for c. 22(T > C. Only 8.3% of the pathogenic alleles were detected. No patients were positive for GJB6 deletion or for A1555G. Conclusions: These findings: (1) demonstrate that GJB2, GJB6 deletion and A1555G mutation account for a minor proportion of NSHHL in the Qatari population, (2) further strengthen the need to search for causative genes, (3) clearly contribute to establishing preventive strategies for NSHHL in Qatar and in the Gulf area.

Design: Qualitative narrative study. Study sample : Twenty-one families participated whose children had been identified with ANSD through the newborn hearing screening programme. Results: The majority of parents in the sample were overwhelmed with perinatal health issues and initially gave the diagnosis of ANSD very low priority. Conclusions: An understanding of parents' perspective is particularly relevant to everyone involved in early support and management of infants with ANSD.

The researchers further wished to analyse the various factors leading to patient satisfaction/dissatisfaction with their Baha. We developed a new questionnaire to obtain a comprehensive impression of individual patient practices, general satisfaction, and experiences with their Baha in respect to time spent using Baha, sound quality, annoyance from noise disturbance, ease of communication, cosmetic appearance, and satisfaction with the Baha amongst patient relatives, an aspect not previously investigated. Design: The study design was retrospective and executed as a postal questionnaire. The questionnaire was developed by the authors of this paper. Study sample: Patients operated on for a Baha at our hospital from 1989 to 2007. Results: The response rate was 92.4%. Eighty-six percent were satisfied or very satisfied with their Baha. Ninety-one percent of respondents could communicate using their Baha in a one-on-one conversational setting. A primary factor leading to dissatisfaction, experienced by 70% of responding patients, was annoyance from wind noise. Conclusions: Baha was found to yield good overall patient satisfaction over the long-term, and it was possible to identify specific factors attributing to satisfaction/dissatisfaction.

The purpose of the present experiment was to determine whether this same effect occurs in far-field recordings, i.e. recordings similar to those made in human subjects. The effect of inhalant anesthesia on ASSR amplitude in response to multiple stimuli was also investigated. Design: Stimuli consisted of three sinusoidally-amplitude modulated tones with carrier/modulation frequencies of (1/.095 kHz), (2/.1 kHz), or (4/.107 kHz). The modulated carriers were presented to the right ear either alone or in combination, while recordings were made from subdermal needle electrodes placed on the head. Study sample: Nine adult chinchillas. Results: A 20%-70% decrease in the response amplitude with the presentation of multiple ASSR-generating stimuli was found, which depended on both carrier frequency as well as stimulus pairing. In general, both the ASSR and the noise floor were reduced under anesthesia. Conclusions: The time savings obtained from presenting multiple stimuli simultaneously may not be as great as initially predicted, as the time saving is at least partially offset by the observed amplitude reduction.

Fibrinogen is known as a risk factor for both microvascular dysfunction and SSNHL. Therefore, the aim of this study was to investigate the effect of elevated serum levels of fibrinogen on cochlear blood flow and hearing function in vivo. Design: One group of guinea pigs received two consecutive injections of 100 mg fibrinogen while a control group received equimolar doses of albumin. Measurements of cochlear microcirculation by intravital microscopy and of hearing thresholds by auditory brainstem response (ABR) recordings were carried out before, after first and after second injection. Study sample: Ten healthy guinea pigs were randomly assigned to a treatment group or a control group of five animals each. Results: Serum fibrinogen levels were elevated after the first and second injections of fibrinogen compared to basal values and control group respectively. Increasing levels of fibrinogen were paralleled by decreasing cochlear blood flow as well as increasing hearing thresholds. Hearing threshold correlated negatively with cochlear blood flow. Conclusions: The effect of microcirculatory impairment on hearing function could be explained by a malfunction of the cochlear amplifier. Further investigation is needed to quantify cochlear potentials under elevated serum fibrinogen levels.

TI Effective masking levels for bone-conducted amplitude- and frequency-modulated tones in adults with normal hearing: A behavioural study SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Effective masking levels; bone conduction; auditory steady-state response; behavioural hearing assessment ID DIFFERENCE; AUDIOMETRY AB Objectives: (1) to estimate the amount of masking needed to eliminate perceptual responses to 1000- and 4000-Hz bone-conducted mixed amplitude-(AM) and frequency-modulated (FM) tonal stimuli in adults with normal hearing, and (2) to compare these findings to recently reported effective masking levels (EMLs) for bone-conducted 80-Hz ASSRs. Design: Stimuli were bone-conducted single sinusoidal tones with carrier frequencies of 1000 and 4000 Hz (Mixed modulation (MM): 100% AM & 25% FM at 85-101 Hz) presented to the temporal bone at 15-45 dB HL for 1000 Hz and 25-35 dB HL for 4000 Hz. Air-conducted 1- and 4-Hz narrow-band noise maskers were presented to both ears simultaneously using ER-3A insert earphones. EMLs for each of the stimuli were determined behaviourally. Study sample: Seventeen adults (mean age: 27.6 years) with normal hearing participated. Results: Overall, EMLs were 10-17 dB higher for perceptual responses compared to ASSRs for 1000 and 4000 Hz. Linear regression analyses revealed that behavioural and ASSR EMLs were not significantly correlated for most of the stimuli presented except for 1000-Hz presented at 45 dB HL (r=.64, p=.013). Conclusions: EMLs are frequency-and testing method-dependent for bone-conducted MM tonal stimuli for normal-hearing adults.

Design: Prospective cross-sectional study through interviews with children and their parents. Study sample: 753 children were selected and invited to participate. The final sample was 475 children and 404 parents. Results: In general, children disliked noisy places (67%). Although 87.4% of the children and 93.9% of the parents considered loud sounds damaging to the ears, children were poorly informed about hearing protection and did not have hearing protection devices. Children were mostly exposed to parties and concerts with loud music (51.9%), carnaval (Mardi Gras) parties (38.2%), firecrackers (36.8%), and loud music at home or in the car (33.1%), or from listening to loud music with earphones (17.3%). Compared to children from private schools, children from public schools had a greater preference for loud sounds and were less informed about hearing protection. Conclusions: Knowledge of hearing risk from loud sounds was not enough to prompt preventive behaviors, and adults exposed children to loud sounds.

Louie, Amber Nahid, Musarrat Shoveller, Jean TI Potential barriers to engineered noise control in food and beverage manufacturing in British Columbia, Canada: A qualitative study SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing conservation program; engineered noise control; qualitative; food and beverage manufacturing ID HEARING PROTECTION USE; WORKERS-COMPENSATION CLAIMS; HEALTH-PROMOTION MODEL; WASHINGTON-STATE; RISK; INTERVENTION; ENFORCEMENT; MANAGEMENT; EXPOSURE; SAFETY AB Objective: Noise is probably the most ubiquitous of occupational hazards. While many jurisdictions require hearing conservation programs (HCP), the most effective intervention engineered noise controls (ENC)-is rarely implemented. We used a qualitative study design to investigate barriers to the implementation of ENC. Design & study sample : Fifty-five individuals at eight food and beverage manufacturers participated. In-depth interviews were conducted and analysed using grounded theory techniques. HCP audits provided contextual information. Results: None of the companies had fully implemented HCP as required by regulation. Many factors emerged as possible barriers to the implementation of engineered noise control, including: poor knowledge of relevant regulations, noise reduction options and the health impacts of noise; weak technical skills and experience; low ranking of noise as a hazard by stakeholders; issues around job insecurity, weak language skills; lack of 'quiet' machine options and information from equipment manufacturers; poor employer-regulator relationships; barriers to employee-employer reporting; informal valuation of ENC costs; and feasibility issues. Conclusions: Potential barriers to the implementation of ENC were identified, and classified at three levels at which they operated. Many barriers could be addressed by a more rigorous application of existing HCP regulation and improvements in education, technical support, and regulatory enforcement.

Results: Median overall daily average levels were 79 and 77 dBLeq(A,8,equiv), with average levels exceeding EPA recommended levels for 70% of participants. Median levels were similar between the hours of 9 a.m. and 9 p.m., and varied little across days of the week. Gender, occupational classification, and history of occupational noise exposure were related to average noise levels, but age, educational attainment, and non-occupational noise exposures were not. Conclusions: A large portion of the general population is exposed to noise levels that could result in long-term adverse effects on hearing. Gender and occupation were most strongly related to exposure, though most participants in this study had occupations that are not conventionally considered noisy.

TI Multivariate DPOAE metrics for identifying changes in hearing: Perspectives from ototoxicity monitoring SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Otoacoustic emission; noise-induced hearing loss; ototoxicity monitoring ID PRODUCT OTOACOUSTIC EMISSIONS; FAST FOURIER-TRANSFORMS; SENSORY CELL LOSS; OUTER HAIR-CELLS; DISTORTION-PRODUCT; NOISE EXPOSURE; SUPPRESSION EXPERIMENTS; IMPAIRED SUBJECTS; BASILAR-MEMBRANE; TEST-PERFORMANCE AB Distortion-product otoacoustic emissions (DPOAEs) provide a window into real-time cochlear mechanical function. Yet, relationships between the changes in DPOAE metrics and auditory sensitivity are still poorly understood. Explicating these relationships might support the use of DPOAEs in hearing conservation programs (HCPs) for detecting early damage leading to noise-induced hearing loss (NIHL) so that mitigating steps might be taken to limit any lasting damage. This report describes the development of DPOAE-based statistical models to assess the risk of hearing loss from cisplatin treatment among cancer patients. Ototoxicity risk assessment (ORA) models were constructed using a machine learning paradigm in which partial least squares and leave-one-out cross-validation were applied, yielding optimal screening algorithms from a set of known risk factors for ototoxicity and DPOAE changes from pre-exposure baseline measures. Single DPOAE metrics alone were poorer indicators of the risk of ototoxic hearing shifts than the best performing multivariate models. This finding suggests that multivariate approaches applied to the use of DPOAEs in a HCP, will improve the ability of DPOAE measures to identify ears with noise-induced mechanical damage and/or hearing loss at each monitoring interval. This prediction must be empirically assessed in noise-exposed subjects.

TI Awarding and promoting excellence in hearing loss prevention SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing loss prevention; hearing conservation; noise-induced hearing loss; occupational health and safety; recognition program ID NOISE EXPOSURE; HEALTH; PROGRAM AB Objective: To describe the rationale and creation of a national award to recognize and promote hearing loss prevention. Design: In 2007, the National Institute for Occupational Safety and Health partnered with the National Hearing Conservation Association to create the Safe-in-Sound Excellence in Hearing Loss Prevention Award (TM) (www.safeinsound.us). The objectives of this initiative were to recognize organizations that document measurable achievements and to share leading edge information to a broader community. Results: An expert committee developed specific and explicit award evaluation criteria of excellence in hearing loss prevention for organizations in different industrial sectors. The general approach toward award criteria was to incorporate current 'best practices' and familiar benchmarks of hearing loss prevention programs. This approach was reviewed publicly. In addition, mechanisms were identified to measure the impact of the award itself. Interest in the award was recorded through the monitoring of the visitor traffic registered by the award web site and is increasing yearly. Specific values and strategies common across award winners are presented. Conclusion: The Safe-in-Sound Award (TM) has obtained high quality field data; identified practical solutions, disseminated successful strategies to minimize the risk of hearing loss, generated new partnerships, and shared practical solutions with others in the field.

This study tests the ANSI S12.42 methods with a range of hearing protection devices measured in field conditions. Design: The method utilizes an acoustic test fixture and three ranges for impulse levels: 130-134, 148-152, and 166-170 dB peak SPL. For this study, four different models of hearing protectors were tested: Bilsom 707 Impact II electronic earmuff, E.A.R Pod Express, E.A.R Combat Arms version 4, and the Etymotic Research, Inc. Electronic BlastPLG (TM) EB1. Study sample: Five samples of each protector were fitted on the fixture or inserted in the fixture's ear canal five times for each impulse level. Impulses were generated by a 0.223 caliber rifle. Results: The average IPILs increased with peak pressure and ranged between 20 and 38 dB. For some protectors, significant differences were observed across protector examples of the same model, and across insertions. Conclusions: The EPA's proposed methods provide consistent and reproducible results. The proposed impulse NRR rating should utilize the minimum and maximum protection percentiles as determined by the ANSI S12.42-2010 methods.

TI Azimuthal auditory localization of gunshots in a realistic field environment: Effects of open-ear versus hearing protection-enhancement devices (HPEDs), military vehicle noise, and hearing impairment SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing protection-enhancement device; electronic hearing protector; level dependent hearing protector; sound localization; impulse noise localization; localization in noise; firearm noise; gunshot; sniper; auditory localization; azimuth ID SOUND LOCALIZATION; LEVEL; AUGMENTATIONS; DESIGN AB Objective: A controlled field experiment was conducted to evaluate localization of suprathreshold gunshot reports (from blank cartridges) with four hearing protection-enhancement devices (HPEDs) in comparison to the open ear with ambient outdoor noise and in 82 dBA diesel military heavy truck noise. Design: Five measures of localization accuracy and response time for eight shooter positions in azimuth were measured. Study sample: Nine normal-hearing and four impaired-hearing participants were tested. Results: Statistical analysis showed worse accuracy and response time performance with the electronic earmuffs (Peltor Com-Tac II (TM) in full gain position) than with the other tested HPEDs (Etymotic EB 1 and EB 15 High-Fidelity Electronic BlastPLG (TM) electronic earplugs, both set to Lo gain positions; and 3M Single-Ended Combat Arms (TM) passive earplug in level-dependent, "open" position). Performance with all HPEDs was worse than that with the open ear, except on right-left confusions, in which the earmuff stood alone as worst, and in response time, for which the EB 1 was equivalent to the open ear. There was no significant main effect of noise on performance. Hearing impairment increased right-left confusions. Subjective ratings related to localization generally corroborated objective localization performance. Conclusions: None of the tested HPEDs preserved "normal" localization performance.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing loss; hearing impairment; hearing aids; help-seeking; older adults; literature review; ICF ID QUALITY-OF-LIFE; AGE; PREVALENCE; EPIDEMIOLOGY; INFORMATION; TECHNOLOGY; PEOPLE AB Objective: The purpose of this review paper was to identify factors that influence older adults' decisions to seek help for hearing impairment and to adopt hearing aids. Design: A literature search of abstracts within peer-reviewed journal articles published in English between 1990 and 2010 was conducted in online bibliographic databases using the keywords: hearing; impair* or loss; seek* or candidate* or applicant* or acquir*; and hearing aid* or help or advice. Results: Twenty-two articles that were directly relevant to this topic were included in this review. Conclusions: The evidence suggests that individuals are more likely to seek help for hearing impairment and/or adopt hearing aids if they: (1) have a moderate to severe hearing impairment and self-reported hearing-related activity limitations or participation restrictions; (2) are older; (3) perceive their hearing as poor; (4) consider there to be more benefits than barriers to amplification; and (5) perceive their significant other/s as supportive of hearing rehabilitation. A barrier to help-seeking for hearing impairment and hearing aid adoption appears to be general practitioners' management of age-related hearing impairment.

Wang, Shouyan Bleeck, Stefan TI Relationship between speech recognition in noise and sparseness SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Glimpsing; babble; Speech intelligibility index; Cocktail party effect ID RECEPTION THRESHOLD; NORMAL-HEARING; FLUCTUATING NOISE; MASKING RELEASE; INTELLIGIBILITY; LISTENERS; SENTENCES; SOUNDS; LEVEL; TIME AB Objective: Established methods for predicting speech recognition in noise require knowledge of clean speech signals, placing limitations on their application. The study evaluates an alternative approach based on characteristics of noisy speech, specifically its sparseness as represented by the statistic kurtosis. Design: Experiments 1 and 2 involved acoustic analysis of vowel-consonant-vowel (VCV) syllables in babble noise, comparing kurtosis, glimpsing areas, and extended speech intelligibility index (ESII) of noisy speech signals with one another and with pre-existing speech recognition scores. Experiment 3 manipulated kurtosis of VCV syllables and investigated effects on speech recognition scores in normal-hearing listeners. Study sample: Pre-existing speech recognition data for Experiments 1 and 2; seven normal-hearing participants for Experiment 3. Results: Experiments 1 and 2 demonstrated that kurtosis calculated in the time-domain from noisy speech is highly correlated (r > 0.98) with established prediction models: glimpsing and ESII. All three measures predicted speech recognition scores well. The final experiment showed a clear monotonic relationship between speech recognition scores and kurtosis. Conclusions: Speech recognition performance in noise is closely related to the sparseness (kurtosis) of the noisy speech signal, at least for the types of speech and noise used here and for listeners with normal hearing.

The focus is on four approaches which have all previously been applied to audiologic research: grounded theory, interpretative phenomenological analysis, conversational analysis, and qualitative content analysis. Conclusions: This article provides a review of methodological issues useful for those designing qualitative research projects in audiology or needing assistance in the interpretation of qualitative literature.

TI Hearing help-seeking and rehabilitation: Perspectives of adults with hearing impairment SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing impairment; Hearing help-seeking; Audiologic rehabilitation; Hearing aids; Qualitative ID QUALITATIVE CONTENT-ANALYSIS; OLDER-PEOPLE; TRUSTWORTHINESS AB Objective: This study investigated the perspectives of adults with hearing impairment on hearing help-seeking and rehabilitation. Design: Individual semi-structured interviews were completed. Study sample: In total, 34 adults with hearing impairment in four countries (Australia, Denmark, UK, and USA) participated. Participants had a range of experience with hearing help-seeking and rehabilitation, from never having sought help to being satisfied hearing-aid users. Results: Qualitative content analysis identified four main categories ('perceiving my hearing impairment', 'seeking hearing help', 'using my hearing aids', and 'perspectives and knowledge') and, at the next level, 25 categories. This article reports on the densest categories: they are described, exemplified with interview quotes, and discussed. Conclusions: People largely described hearing help-seeking and rehabilitation in the context of their daily lives. Adults with hearing impairment rarely described clinical encounters towards hearing help-seeking and rehabilitation as a connected process. They portrayed interactions with clinicians as isolated events rather than chronologically-ordered steps relating to a common goal. Clinical implications of the findings are discussed.

Design: REIGs were compared for the two methods using a warble tone sweep at 65 dB SPL. The differences between the two methods at 0.25, 0.5, 1, 2, 3, 4 and 6 kHz were recorded. Study sample: Eighty-three ears of a consecutive sample of 48 candidates for open-fit hearing aids were included. Results: The mean difference between MPSE and MPCE REIGs was less than 1 dB at all frequencies. Analysis of variance showed that the main effect of method was not significant, and there was no significant interaction between method and frequency. Conclusions: The results for the MPSE and MPCE methods did not differ significantly for the patients with mild-to-moderate hearing losses tested here, for whom REIGs were generally less than 20 dB. Further research is needed to identify the REIG values at which the differences between MPCE and MPSE methods become clinically significant.

Design and study sample: Three hundred and forty-six elderly adults participated in a survey that included questionnaires and home visits. Fifty-five percent of participants admitted to having hearing difficulties, and 59% of these owned hearing aids. The participants' most frequently cited reason for not acquiring hearing aids was that they did not think their hearing problem was perceived as severe enough. Participants with hearing difficulties who did not own hearing aids showed worse general and mental health. Many of the elderly participants were successful in their rehabilitation, and their hearing-aid outcomes were similar to those of a younger group, with the exception of a greater proportion of non-users among the elderly. Conclusion: Many older people with self-reported hearing difficulties do not acquire hearing aids, despite this study's findings that older people are likely to have success with hearing rehabilitation. It is important to make greater efforts to try to increase elderly adults' awareness of hearing loss and the benefits of hearing rehabilitation.

Design: Multiple ASSRs to AM, FM, and MM to 0.5, 1, 2, and 4 kHz tones modulated between 0.078 and 0.092 kHz were recorded and compared. MM phase settings across the cycle at 45 intervals were used and optimum phase settings were predicted using a sinusoidal model. Study sample: Twenty neonates with click ABR thresholds of <= 40 dB nHL. Results: ASSR amplitudes were significantly larger to AM than FM stimuli. MM phase setting had a significant effect on amplitude at 1, 2, and 4 kHz but not 0.5 kHz. MM phase settings (+/- 95% confidence intervals) of 276 (+/- 9.5 degrees) and 270 (+/- 19.1 degrees) were predicted for 1 and 2 kHz, respectively. The 0.5 and 4 kHz data were not sufficient to model any effect of phase. MM and AM response latencies increased with decreasing carrier frequency. Some MM response latencies were significantly different from AM response latencies, however no consistent trend was apparent. Test times were significantly affected by phase setting. Conclusions: MM phase settings have a significant effect on ASSR response amplitude and latencies in neonates.

Although a structural basis for the abnormality has been widely accepted, the influence of cognitive variables on the degree of observed asymmetry has gained increasing attention. To study this issue, we manipulated cognitive influences on interaural asymmetry in an adult with the auditory complaints typically associated with APD. Study sample: A 55 year-old woman with complaints of difficulty understanding speech in noisy environments despite normal audiometric levels. Design: Several experimental dichotic procedures were administered. Each procedure was characterized by the manipulation of cognitive task demands. Results: Interaural asymmetry was greatest when the demands on attention and/or memory were maximal. Electrophysiological data revealed interaural asymmetry on later stages of information processing. Conclusions: Results are discussed in relation to auditory-specific outcomes on clinical tests for APD.

Study sample: The questionnaires were administered to a group of 290 hearing-aid candidates (ECHO) and 462 experienced hearing-aid users (SADL) recruited at different audiological centres in Germany. Design: The psychometric properties of the German versions and the original questionnaires were similar as confirmed by factor analysis and internal consistency analysis. Results: When comparing outcomes for the ECHO and SADL inventories from the two study groups it was found that satisfaction outperformed expectations. In addition, the relationships of the questionnaire subscales with personality traits as measured with the Big Five inventory were examined. Certain weak though statistically significant correlations were found revealing that personality in hearing-impaired persons does not greatly affect ECHO and SADL outcomes. In contrast, ECHO subscale scores were clearly associated with the motivation to use amplification and might thus help to detect non-adherents. Conclusion: These findings, along with the fact that pre-fitting expectations can be directly compared to post-fitting satisfaction, makes the application of the ECHO and SADL inventories highly valuable in rehabilitative audiology.

Huggard, Peter TI Occupational stress amongst audiologists: Compassion satisfaction, compassion fatigue, and burnout SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Occupational stress; burnout; compassion fatigue; compassion satisfaction; healthcare professional; audiologist ID SUPPORT; NURSES; CARE AB Objective : This study aimed to investigate occupational stress amongst audiologists, along with quantification of their professional quality of life: Burnout, compassion fatigue, and compassion satisfaction. Design : A cross-sectional postal survey research design using an audiology occupational stress questionnaire (AOSQ), and the professional quality of life (ProQOL) instrument. Study sample : The sample consisted of members of the New Zealand Audiological Society. One hundred and forty-five questionnaires were mailed, 82 responses were received. Results : The main findings suggest that six stress factors dominate clinical audiology: (1) time demand, (2) audiological management, (3) patient contact, (4) clinical protocol, (5) patient accountability, and (6) administration or equipment. A significant relationship was found between increasing age of the audiologist and risk of acquiring burnout (chi-square (1) = 6.119, p < 0.05). Pearson's correlation's revealed time demand was the strongest predictor of low compassion satisfaction (r = 0.327) and burnout (r = 0.463), while stress associated with patient contact was the strongest predictor of compassion fatigue (r = 0.352). Conclusions : This study identifies sources of stress for clinical audiologists and different factors that contribute to professional quality of life.

Primary open-angle glaucoma, a neurodegenerative disease of the optic nerve, has recently been associated with a spectrum of mitochondrial abnormalities. This study sought to investigate auditory processing in individuals with open-angle glaucoma. Design/Study sample: Twenty-seven subjects with open-angle glaucoma underwent electrophysiologic (auditory brainstem response), auditory temporal processing (amplitude modulation detection), and speech perception (monosyllabic words in quiet and background noise) assessment in each ear. A cohort of age, gender and hearing level matched control subjects was also tested. Results: While the majority of glaucoma subjects in this study demonstrated normal auditory function, there were a significant number (6/27 subjects, 22%) who showed abnormal auditory brainstem responses and impaired auditory perception in one or both ears. Conclusions: The finding that a significant proportion of subjects with open-angle glaucoma presented with auditory dysfunction provides evidence of systemic neuronal susceptibility. Affected individuals may suffer significant communication difficulties in everyday listening situations.

Effect of wide dynamic range compression and modulation-based noise reduction SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aid; wind; wide dynamic range compression; modulation-based; noise reduction ID MICROPHONES POLAR CHARACTERISTICS AB Objective: The objectives of this study were: (1) to examine the effect of wide dynamic range compression (WDRC) and modulation-based noise reduction (NR) algorithms on wind noise levels at the hearing aid output; and (2) to derive effective strategies for clinicians and engineers to reduce wind noise in hearing aids. Design: Three digital hearing aids were fitted to KEMAR. The noise output was recorded at flow velocities of 0, 4.5, 9.0, and 13.5 m/s in a wind tunnel as the KEMAR head was turned from 0 to 360. Study sample: Flow noise levels were compared between the 1:1 linear and 3:1 WDRC conditions, and between NR-activated and NR-deactivated conditions when the hearing aid was programmed to the directional and omnidirectional modes. Results: The results showed that: (1) WDRC increased low-level noise and reduced high-level noise; and (2) different noise reduction algorithms provided different amounts of wind noise reduction in different microphone modes, frequency regions, flow velocities, and head angles. Conclusions: Wind noise can be reduced by decreasing the gain for low-level inputs, increasing the compression ratio for high-level inputs, and activating modulation-based noise reduction algorithms.

Effect of microphone directivity SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aid; cochlear implant; wind; polar pattern; directionality; directional; omnidirectional; microphone ID POLAR CHARACTERISTICS AB Objectives: The objectives were: (1) to examine the effects of a directional microphone with different directivity patterns and different microphone combinations on wind noise levels at the hearing aid output; and (2) to derive strategies appropriate for hearing aid selection and future designs. Design: The in-situ frequency responses of a behind-the-ear hearing aid (BTE1) were matched when the hearing aid was programmed to dipole, hypercardioid, cardioids, or adaptive microphone mode. The in-situ frequency responses of another hearing aid (BTE2) were matched among an omnidirectional microphone (OMNI), an adaptive directional microphone (ADM), and a combination of an omnidirectional microphone at low frequencies and an adaptive directional microphone at high frequencies (MIXED). Flow noise was recorded at flow velocities of 0, 4.5, 9.0, and 13.5 m/s. Measurements were repeated for the hypercardioid pattern of BTE1. Study sample: Flow noise recorded using directional microphones with four directivity patterns and using OMNI, ADM, and MIXED. Results: Directional microphones with different directivity patterns generated similar flow noise levels. ADM yielded higher overall levels than OMNI and MIXED, which had similar overall levels. Conclusions: The adaptive directional microphone is the most versatile microphone for use in wind. The mixed microphone mode is a viable wind noise reduction option.

Design: A parallel case study design was adopted. Communication dyads undertook a 20-minute conversation followed by a 20-minute session of tracking. The interactions were audio-recorded, transcribed, and analysed for patterns of repair according to current conversation analytic conventions (Schegloff et al, 1977). The research questions were addressed via both qualitative and quantitative methods. Study sample: Three communication pairs (dyads), each comprising an adult with acquired hearing impairment and their chosen familiar communication partner, participated in this study. Results: Analysis revealed that patterns of repair were constrained by the task requirement in tracking for the receiver/hearing-impaired adult to repeat text segments spoken by the sender/familiar communication partner with 100% accuracy. Conclusions: Whilst tracking has a number of useful conversational qualities, it may have only limited ecological validity when applied to the evaluation and training of repair behaviour.

Since 2006 in Flanders and 2009 in the Netherlands, both programs have replaced the older ALGO Portable devices with the newer ALGO 3i devices. However, in both countries, ALGO 3i devices have a significantly higher rate of referrals than ALGO Portable devices. In Flanders, the refer rate has more than doubled with the switch to ALGO 3i devices. In the Netherlands, screening centers which used ALGO 3i devices also showed a significant increase in referrals. In both countries, the percentage of children diagnosed with permanent hearing loss remained approximately the same. Design: A technical comparison of both device types was carried out to identify possible causes for the increase in referrals. The stimulus output of two ALGO Portable and three ALGO 3i devices was recorded and analysed for stimulus level, spectral properties, and stimulus irregularities. Results: ALGO 3i devices stimulate at a peak level 4.6 dB lower than ALGO Portable devices, have a different stimulus spectrum and show unexplained stimulus irregularities during 4% of the stimulation time. Conclusions: A number of technical differences were found between both device types which could explain the increase in referrals.

Design: The TFS1 test was described by Moore and Sek (2009). The task is to discriminate a harmonic complex tone from a tone in which all frequency components are shifted upwards by the same amount in Hz. The TFSLF test was described by Hopkins and Moore (2010a). The task is to detect changes in lateral position of a binaurally presented tone based on interaural phase difference (IPD). Both tests have been implemented in software that can be run on a PC with a good-quality sound card. The software includes a routine for measuring the absolute threshold at the test frequency. Results: For each test, an experimental run at a single frequency takes about three minutes. Practice tasks (frequency discrimination of pure tones for TFS1 and discrimination of changes in lateral position based on interaural level difference for TFSLF) are also implemented that are similar to the main task, but easier. Conclusions: The software implementation allows sensitivity to TFS to be measured quickly without a requirement for specialized equipment. C1 [Sek, Aleksander; Moore, Brian C.

The current study aimed to look at attitudinal factors that influence practitioners' decisions to discuss hearing difficulties with older patients and refer them for hearing rehabilitation. Design: A questionnaire based on constructs from the Health Belief Model was used to examine factors that may influence practitioners' referral decisions. Study Sample: One hundred and ten practitioners' attitudes to hearing rehabilitation were examined. Results: The results indicated that practitioners have a high level of awareness about their older patients' susceptibility to hearing loss, and a good understanding of the severity of the associated impacts on older adults' lives. Although practitioners acknowledged the theoretical benefits of hearing rehabilitation, many appear less certain about the potential for actual benefit for their older adults. Barriers to referral include negative perceptions about how older patients prioritise hearing, and patients' ability to afford and adapt to the use of hearing aids. Conclusions: Additional research and education targeted at these area may be beneficial for medical practitioners to increase referral behaviour and improve discussions about hearing rehabilitation with their older patients.

Study sample: Forty-six normal-hearing, solvent-exposed subjects and 46 normal-hearing, control subjects were selected to participate in the study. Design: All subjects must present with normal hearing thresholds and absence of history of variables related to the onset of auditory dysfunction. Subjects were evaluated with a test battery comprising pure-tone audiometry (PTA), dichotic digits (DD), pitch pattern sequence (PPS), filtered speech (FS), random gap detection (RGD), masking level difference (MLD), and hearing-in-noise (HINT) tests. Results: Analyses of covariance (ANCOVA) were performed to compare the mean values of the dependent variables (results for DD, PPS, FS, RGD, MLD, and HINT) between solvent-exposed and control subjects. Age and average hearing thresholds (500-8000 Hz) were included in the analyses as covariates. Significant differences for DD, PPS, FS, and RGD results were found between groups. Conclusion: This study provides further evidence of the central auditory dysfunction associated with solvent exposure.

Design : DNA samples from non-syndromic hearing-impaired infants enrolled in a neonatal screening programme for sensorineural hearing loss were analysed by PCR and by direct sequencing. The audiological features of infants with biallelic GJB2 mutations were also examined to identify genotype-phenotype correlations. Study sample : Molecular analyses were carried out in 129 affected and five unaffected infants. Results : A genetic etiology of hearing loss was identified in 28% of infants, including several at environmental risk of hearing loss. Neither GJB6 nor GJB3 (a gene not previously investigated in the Campania population) mutations were found. Conclusions : This study confirms the importance of universal neonatal hearing screening. The identification of a genetic cause in infants at environmental risk indicates that such infants should be included when investigating etiology. We confirm that also in our geographical area, c.35delG homozygotes tend to have severe symmetrical hearing loss, whereas hearing impairment is milder in compound heterozygotes.

Design: A repeated-measures meta-analytical approach was used to compare effect sizes between binaural CI arrangements for each of the three binaural-listening phenomena and between the two test paradigms. Study sample: A total of 95 effect sizes were calculated and analyzed from 42 peer-reviewed studies published between January 2000 and April 2011. Results: Findings revealed significant effect sizes for both CI arrangements for the binaural phenomena of summation and head-shadow effect. A significant effect size for binaural squelch was determined only for bilateral CI users. Further, the two paradigms resulted in similar effect sizes for bilateral and bimodal users, with the exception of binaural squelch. Here, significant effect sizes were significant only in the fixed-testing paradigm. Conclusions: The average user of binaural CI arrangements realizes the binaural phenomena of summation and the head-shadow effect, but only the bilateral CI arrangement is afforded the advantage of binaural squelch. Statistically, listeners fit with bilateral CIs have a slight advantage in binaural performance over those using bimodal stimulation.

Study sample: This study involved 26 subjects who had previously undergone NTT at a single private practice. Design: Patients with high level of hearing loss were divided into two groups: Standard protocol group (SP) concluded the treatment following the standard NTT protocol proposed by the treatment's developers and Neuromonics guidelines. Extended protocol group (EP) was treated using a variation of the standard protocol, in which patients continued in stage 1 of the treatment for a prolonged time. Consistent with previously reported studies of the NTT, the tinnitus reaction questionnaire was used to assess tinnitus distress. Clinical outcomes for the two groups were analysed. Results: Both groups achieved statistically significant improvement of their tinnitus distress. EP group achieved quicker clinical benefits when compared to the SP group. Conclusions: Extension of high stimulation period from two to four months may be beneficial for patients with higher level of hearing loss undergoing NTT.

TI Prospective effects of hearing status on loneliness and depression in older persons: Identification of subgroups SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing status; depression; loneliness; older persons; longitudinal ID QUALITY-OF-LIFE; NOISE SCREENING-TEST; IN-NOISE; PSYCHOSOCIAL HEALTH; ELDERLY POPULATION; MENTAL-HEALTH; IMPAIRMENT; COMMUNITY; ASSOCIATION; ADULTS AB Objective : To determine the possible longitudinal relationships between hearing status and depression, and hearing status and loneliness in the older population. Design : Multiple linear regression analyses were used to assess the associations between baseline hearing and 4-year follow-up of depression, social loneliness, and emotional loneliness. Hearing was measured both by self-report and a speech-in-noise test. Each model was corrected for age, gender, hearing aid use, baseline wellbeing, and relevant confounders. Subgroup effects were tested using interaction terms. Study sample : We used data from two waves of the Longitudinal Aging Study Amsterdam (2001-02 and 2005-06, ages 63-93). Sample sizes were 996 (self-report (SR) analyses) and 830 (speech-in-noise test (SNT) analyses). Results : Both hearing measures showed significant adverse associations with both loneliness measures (p < 0.05). However, stratified analyses showed that these effects were restricted to specific subgroups. For instance, effects were significant only for non-hearing aid users (SR-social loneliness model) and men (SR and SNT-emotional loneliness model). No significant effects appeared for depression. Conclusions : We found significant adverse effects of poor hearing on emotional and social loneliness for specific subgroups of older persons. Future research should confirm the subgroup effects and may contribute to the development of tailored prevention and intervention programs.

Design: Clinical assessments (Tinnitus Handicap Inventory: THI, visual analog scale to rate the degree of the tinnitus: VAS, hearing levels in pure-tone audiometry) were conducted upon entry into the study (baseline) and at 12 weeks follow-up (week 12). Blood sampling to measure HPA axis-related hormones took place between 9: 00 and 10: 00 a. m. at baseline and at 12 weeks follow-up. Study samples: This study consisted of 20 unilateral Meniere's disease patients and 21 patients with other diseases with unilateral sensorineural hearing loss and tinnitus. Results: A significant deterioration of the hearing level at high frequency range, especially at 2 kHz, was found during the 12 weeks follow-up in the Meniere's disease group (p < 0.05). The average hearing levels significantly correlated with the serum cortisol level at baseline and week 12 in the Meniere's disease group, especially regarding the high frequency levels (p < 0.01). Conclusions: Our results suggest that the cortisol levels influence the endolymphatic homeostasis resulting in a deterioration of hearing at high frequency with upstaging of Meniere's disease.

TI The speech intelligibility benefit of a unilateral wireless system for hearing-impaired adults SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing impairment; speech intelligibility; wireless technology ID FM SYSTEMS; AID DELAYS; NOISE; RECOGNITION; PERFORMANCE; AUDIBILITY AB Objective: This study measured the effects of two previously untested practical considerations-venting and transmission delays-on speech intelligibility in a simulated unilateral wireless system, where a target signal in background noise was transmitted wirelessly to the hearing-impaired (HI) listener. Design: Speech reception thresholds (SRTs) relative to the signal-to-noise ratio (SNR) were measured by varying the surrounding babble noise level. The target signal was presented at 0 degrees azimuth in the soundfield and unilaterally via an insert earphone, using open and closed fittings with simulated-wireless delays ranging between 0-160 ms. SRTs were also measured unaided and with participants' current hearing aid(s). Study sample: Thirty-three mild-to-moderate sensorineural HI adults participated in the experiment. Results: For an open fitting, the results showed a 5-dB SNR benefit in SRT compared to unaided performance at shorter delays. For a closed fitting, the majority of participants could accurately recognize speech below - 20 dBSNR across delays. Conclusions: These results highlight the efficacy of wireless systems with HI adults. Speech-intelligibility benefits are affected by transmission delays only when the delay is greater than 40 ms and the coupling is vented.

Design: Perceptual evaluations of intelligibility, phonation, resonance, and articulation were compared between the several subgroups. Study sample: Thirteen biCI children, 14 uniCI children, 10 HA children using hearing aids and 11 NH children participated. Results: The biCI children did not show statistically significant differences with the NH children for overall intelligibility, phonation, and resonance. Yet, significantly more distortions and consonant cluster reductions were observed in the biCI children compared with the NH children. In comparison with the uniCI and HA children, the NH as well as the biCI children obtained better evaluations for intelligibility, phonation, resonance, and articulation of consonants. Conclusions: The results of this study demonstrated a possible additional beneficial effect of bilateral implantation on several speech characteristics of prelingually deaf children and as a consequence highlighted the interest of further research.

Design: Subjects wore the devices in daily life in a crossover study for periods ranging from 25 to 63 days. A speech-in-noise test was carried out as well as measures of noise reduction and feedback suppression algorithms. User satisfaction was reported using the NSH and the GHABP questionnaires. At the end of the test, subjects selected one of the devices for permanent use. Study sample: Twelve first-time users of BAHIs. Results: Eight subjects selected the Ponto Pro; four selected the BP100. The Ponto Pro was rated as easier to operate than the BP100, the visual appearance of the Ponto Pro was rated as nicer than that of the BP100, and speech understanding was rated higher with the Ponto Pro than with the BP100. Speech-in-noise tests showed improvements using directional microphones with the Ponto Pro. Conclusions: 67% of the subjects opted for permanent use of the Ponto Pro, which, compared to the BP100, was rated to have a nicer look, to be easier to operate, and to yield better speech intelligibility.

Listening effort refers to the attentional and cognitive resources required to understand speech. Design : All participants performed a closed-set word recognition task and tactile pattern recognition task separately and concurrently. Accuracy and reaction time data were collected. The criterion for single task word recognition performance was set to 80% correct across experiments and across age groups. Study sample : For each experiment, 25 young and 25 older adults with normal hearing and normal (or corrected normal) vision participated. Results : Under equated performance conditions, older adults expended more listening effort than young adults with both audio-only and audiovisually presented speech. Furthermore, the processing demands of audiovisual speech recognition were greater than audio-only speech recognition for all participants. Conclusions : These results suggest that while visual cues can improve audiovisual speech recognition, they can also place an extra demand on processing resources with performance consequences for the word and tactile tasks under dual task conditions.

The aim of this study was to investigate the prevalence of different audiogram configurations among older adults. In addition, audiogram configurations among subjects reporting hearing problems were examined. Design : Cross-sectional, population-based, unscreened epidemiological study among older adults. Study sample : The subjects (850), aged 54-66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed. Results : The most prevalent audiogram configuration among men was high-frequency steeply sloping (65.3% left ear, 51.2% right ear) and among women, high-frequency gently sloping (33.0% left ear, 31.5% right ear). There were significantly more flat configurations among women than among men. Unclassified audiograms were common especially among women (17.5%). Subjects reporting hearing difficulties, difficulties in following conversation in noise, or tinnitus, more often had a high-frequency steeply sloping configuration than those not reporting. Conclusions : High-frequency sloping audiogram configurations were common among older adults, and a high-frequency steeply sloping configuration was common among those reporting hearing problems.

As a first step, the current investigation trained participants using either a single talker or multiple talkers to determine if auditory training leads to transfer-appropriate gains. Design : The experiment implemented a 2 x 2 x 2 mixed design, with training condition as a between-participants variable and testing interval and test version as repeated-measures variables. Participants completed a computerized six-week auditory training program wherein they heard either the speech of a single talker or the speech of six talkers. Training gains were assessed with single-talker and multi-talker versions of the Four-choice discrimination test. Participants in both groups were tested on both versions. Study sample : Sixty-nine adult hearing-aid users were randomly assigned to either single-talker or multi-talker auditory training. Results : Both groups showed significant gains on both test versions. Participants who trained with multiple talkers showed greater improvement on the multi-talker version whereas participants who trained with a single talker showed greater improvement on the single-talker version. Conclusion : Transfer-appropriate gains occurred following auditory training, suggesting that auditory training can be designed to target specific patient needs.

Design: Prospective birth cohort study. Study sample : Repeat hearing thresholds were measured in 5032 children, as part of the Avon Longitudinal Study of Parents and Children (ALSPAC) at age 7, 9, and 11 years. Pregnancy, birth, and early medical history were obtained prospectively through parental questionnaires and medical records. Results: Twenty children had mild and seven had high-frequency bilateral sensorineural hearing loss, giving a combined prevalence of 0.5% (95% CI 0.4-0.8%). These children were more likely than the rest of the study sample to have been admitted to hospital at 6-18 months (OR 2.7, 95% CI 1.00-7.30). Parents of these children were more likely to have suspected a hearing problem when the children were 3 years old (OR 2.4, 95% CI 1.05-5.60). Conclusions: This is the first UK prospective cohort study to investigate the prevalence of mild and high-frequency hearing loss. This study, which has the advantage of a large sample size and repeat hearing measures over a four year period, reports lower prevalence values than US cross-sectional studies.

Design : Subjects underwent videonystagmography including saccades, smooth pursuit (SP), optokinetic test (OKN), gaze nystagmus assessment, bithermal caloric test, and static posturography. Study sample : Study groups included 74 workers in plastics manufacturing, aged 40 (SD 8) years, exposed to styrene and dichloromethane, and the reference group of 49 non-exposed subjects, aged 36 (SD 10) years. Results : More than 60% of exposed and non-symptomatic workers revealed abnormal results of vestibular tests. Saccadic latency elongation (p = 0.0098), lower gain in SP (p = 0.0037) and OKN (p = 0.0000) were more common in the exposed group, as well as lower reactivity (p = 0.0337) and mean slow phase velocity of caloric nystagmus. Static posturography revealed higher sway velocities in the test with eyes closed, on foam and worse results of three from five limit of stability tests. No relationship between chemicals exposure and vestibular and balance test results was found. Conclusions : In principle, our findings indicate the possibility of high-level deficits in the central part of vestibular system. Lower vestibular reactivity may suggest that bilateral vestibular hypofunction might also be the possible consequence of solvent exposure.

These tests are adaptive speech-in-noise tests using either digit triplets or monosyllables, presented in stationary speech-shaped noise. These tests can be highly valuable in increasing the awareness and prevention of noise-induced hearing loss (NIHL). This study evaluates these online speech-in-noise tests and investigates their potential to detect NIHL. Design: In a multi-centre study the results of the three online screening tests are compared to pure-tone audiometry and to the Dutch sentence SRT test (Plomp & Mimpen, 1979a), which is considered the clinical standard. Study sample : In total, 49 normal-hearing listeners and 49 patients with different degrees of NIHL participated. Results : The online tests show good reliability, but there is much overlap in outcomes between normal-hearing listeners and participants with early NIHL. In addition, rather low correlations of the test results with both the Dutch sentence SRT test and pure-tone thresholds are found. These findings result in rather low test sensitivity: 54% (NHT) and 51% (EC), or low specificity: 49% (OEC). Conclusions: The online screening tests in their current form are unsuitable to be used for early NIHL screening purposes. C1 [Leensen, Monique C.

TI Speech-in-noise screening tests by internet, Part 2: Improving test sensitivity for noise-induced hearing loss SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Noise-induced hearing loss; Speech-in-noise; Self-screening; Speech reception threshold; Non-stationary noise; Prevention ID RECEPTION THRESHOLD; IMPAIRED LISTENERS; FLUCTUATING NOISE; WORD RECOGNITION; YOUNG-ADULTS; INTELLIGIBILITY; ADOLESCENTS; MUSIC; PREVALENCE; DISORDERS AB Objective : An easily accessible screening test can be valuable in the prevention of noise-induced hearing loss (NIHL). The Dutch National Hearing Foundation developed 'Earcheck', an internet-based speech-in-noise test, presenting CVC-words in stationary broadband noise. However, its sensitivity to detect NIHL appeared to be low, 51% (Leensen et al, 2011, part 1). The aim of the current study is to examine ways to improve Earcheck's sensitivity for (early) NIHL using different forms of noise filtering. Design : The test's stationary broadband masking noise is replaced by six alternatives, including noises that have been temporally modulated, spectrally filtered by high-pass or low-pass filters, and combinations of temporal modulation and spectral filtering. Study sample : In this multi-centre study, 49 normal-hearing and 49 subjects with different degrees of NIHL participated. Results : Hearing-impaired subjects deviated more clearly from normal performance when executing the test with alternative masking noises, except for the high-pass filtered conditions. Earcheck with low-pass filtered noise made the best distinction between normal hearing and NIHL, without reducing test reliability. The use of this noise condition improved the sensitivity of Earcheck to 95%. Conclusion : The use of low-pass filtered masking noise makes speech-in-noise tests more sensitive to detect NIHL in an early stage. C1 [Leensen, Monique C.

Design: Over a period of one year, clinicians implemented their usual protocol and recorded a brief history for those with normal audiometry. Study Sample: The number of people seen by the service was 2924 children (0-16 years old) and 4757 adults (17-100 years old). Results: Adults and school-age children were most commonly referred by their primary care doctor for difficulties listening in noise or following a conversation, and younger children by their home health visitor for speech production problems. Children tended to be referred on to speech pathology or APD clinics whereas adults were discharged. Conclusions: The prevalence of normal cases was 5.1% among the children and 0.9% among all adults. For younger adults (17-60 years, n = 1025), the prevalence was 4.0%. Based on comparison with those referred with hearing loss, we estimate the prevalence of APD among children and adults, defined as listening problems despite normal audiometry, to be about 0.5-1.0% of the general population.

Design: Subjects diagnosed with cancer and treated with platinum-based chemotherapy in childhood underwent audiometric evaluations. Study Sample: Fifteen subjects (eight females and seven males) fulfilled the criteria set for the study, and four of those received customized open-fitting hearing-aids. Results: Subjects with cisplatin-induced ototoxicity had severe difficulties recognizing words in noise, and scored as low as 54% below reference scores standardized for age and degree of hearing loss. Hearing-impaired subjects' self-reported hearing-handicap correlated significantly with word recognition in a quiet environment but not in noise. Word recognition in noise improved markedly (up to 46%) with hearing-aids, and the self-reported hearing-handicap and disability score were reduced by more than 50%. Conclusions: This study demonstrates the importance of testing word recognition in noise in subjects treated with platinum-based chemotherapy in childhood, and to use specific custom-made questionnaires to evaluate the experienced hearing-handicap. Open-fitting hearing-aids are a good alternative for subjects suffering from poor word recognition in noise.

Design: This cross-sectional study was conducted as part of NoiseChem, a European Commission 5th Framework Programme research project, by occupational health institutes in Finland, Sweden, and Poland. Study sample: Participants' ages ranged from 18-72 years (n = 1620 workers). Participants exposed to styrene, alone or with noise, were from reinforced fiberglass products manufacturing plants (n = 862). Comparison groups were comprised of workers noise-exposed (n = 400) or controls (n = 358). Current styrene exposures ranged from 0 to 309 mg/m(3), while mean current noise levels ranged from 70-84 dB(A). Hearing thresholds of styrene-exposed participants were compared with Annexes A and B from ANSI S3.44, 1996. Results: The audiometric thresholds of styrene exposed workers were significantly poorer than those in published standards. Age, gender, and styrene exposure met the significance level criterion in the multiple logistic regression for the binary outcome 'hearing loss' (P = 0.0000). Exposure to noise (<85 dBA p = 0.0001; >= 85 dB(A) p = 0.0192) interacted significantly with styrene exposure. Conclusions: Occupational exposure to styrene is a risk factor for hearing loss, and styrene-exposed workers should be included in hearing loss prevention programs.

Design: Cross-sectional study. The IOI-HA was administered in a paper and pencil format. Study sample: The IOI-HA and self-designed questionnaire were mailed to 1502 experienced hearing-aid users who received their hearing aids from 14 hearing service centers in mainland China. In all, 1049 completed responses were included in the final analysis, and descriptive statistics were reported. Results: The mean scores of each item of the IOI-HA ranged from 3.55 to 4.16. The IOI-HA scores showed a skewed distribution, with the maximum frequency for a score of 4 or 5. The total IOI-HA scores ranged from 9 to 35, and the mean total score was 26.3. The results compared favorably with the previous reports, and slightly higher than the published norms, indicating a high level of self-reported outcomes. Conclusiones: The IOI-HA could be used as an effective tool to measure the general effectiveness of the hearing aid outcomes in China. The implementation of the IOI-HA is time-efficient, imposing little burden on the clinician and patient.

This study examined parents' perceptions of the decision process and of the benefits of two implants. Design: The study adopted a qualitative approach, examining parents' views through individual semi-structured interviews. Study sample: The participants consisted of the parents of 15 children at one centre in Ontario, Canada, where 26 children had received bilateral implants. Children ranged in age from 1.8 to 11.9 years and their experience with two implants ranged from 0.3 to 4.2 years. Results: Parents described decision-making as relatively straightforward. However, many parents shared concerns related to surgery. Primary reasons for choosing two implants were neuroplasticity, preference for a backup device, and maximizing potential through technology. Expected outcomes included better speech understanding in noise and the ability to locate the source of sounds. Perceived benefits of bilateral implantation included improved speech understanding in noise, the availability of a backup implant, and parents' assurance that they had provided their children with the best possible access to hearing. Conclusions: Overall, parents were satisfied with the second implant and identified benefits that are not easily quantifiable through traditional clinical measures.

Roxann TI A study of recorded versus live voice word recognition SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech audiometry; Speech recognition; Word recognition; Monitored live voice; Recorded ID SPEECH-DISCRIMINATION; SCORES; INTELLIGIBILITY AB Objective: To determine administration times for word recognition presented via monitored live voice (MLV) and compact disc (CD) recordings. Design: A quasi-experimental design was used. Fifty-word NU-6 lists were presented in three conditions: (1) MLV, (2) short ISI CD recording, and (3) long ISI CD recording. Study sample: Listeners with normal hearing (NH) and hearing impairment (HI) participated in this study. Results: Average administration time using MLV was significantly shorter than using recorded word lists for both groups of listeners. MLV presentation to the NH listeners was significantly faster than the MLV presentation to the HI listeners. There were no significant differences between groups in the administration times for any of the recorded lists (long or short ISI). Considerably more variability in administration time was observed for MLV presentation compared to recorded presentations. Conclusions: MLV presentation was about one minute faster than the shortest CD recording of the NU-6 fifty-item word lists, but it was only 49 seconds quicker when administering tests to individuals with hearing loss. Because the majority of our patients are hearing impaired, the difference of 49 seconds is not clinically significant. This difference is even less when 25-item word lists are used.

However, only a few studies have investigated carrier frequencies of GJB2 mutations in the general population. The aim of this study was to estimate the carrier frequencies of three GJB2 mutations, including 235delC, V37I, and G45E, in the general Korean population. Design: A standard questionnaire of self-reported hearing loss was used to identify and recruit subjects. Screening for three mutations was performed using an allele-specific polymerase chain reaction (PCR), PCR-restriction fragment length polymorphism, and direct DNA sequencing. Study sample: A total of 1256 unrelated healthy individuals were analysed in the present study. Results: Of the 1256 individuals, 24 had GJB2 mutations; 11 were found to be heterozygous for 235delC, 11 were heterozygous and one was homozygous for V37I, and one was heterozygous for G45E. One individual had a compound heterozygous mutation of 235delC/V37I. The allele frequencies of 235delC, V37I, and G45E mutations were 0.44%, 0.52%, and 0.04%, respectively. The carrier frequency of either the 235delC or V37I mutation was estimated to be 0.88% with 95% binomial CI, 0.44-1.56. Conclusions: These results will facilitate diagnosis of, and genetic counseling for, hearing loss in Koreans.

Design: A qualitative research paradigm called qualitative description was selected to address this issue. Study sample: Twelve people who had an adult onset hearing loss, and were gainfully employed, participated in audio-recorded semi-structured interviews designed to probe issues related to disclosure of hearing loss. A photo elicitation interview technique was employed during the interviews. Content analyses were used to extract pertinent information from verbatim transcripts. Results: Five recurring themes emerged as important considerations in relation to this topic: (1) perceived importance of the situation; (2) perceived sense of control; (3) community affiliation; (4) burden of communication; and (5) coexisting issues related to hearing loss. Conclusions: The findings are discussed in relation to other concealable stigmatizing traits, stigma-theory, and social-cognitive theory. The clinical implications of these findings are discussed, with particular emphasis placed on worker self-efficacy.

Specific diagnoses of otological and audiological disorders, which can result in hearing loss, were searched for. Design: A retrospective register study. Study sample: Three age cohorts, 474 70- and 75-year olds ("younger"), and 252 85-year olds ("older"), were studied. Clinical pure tone and speech audiometry was used. Data from medical files were included. Results: Conductive hearing loss was diagnosed in 6.1% of the "younger" elderly persons, and in 10.3% of the "older" ones. Specific diagnoses ( chronic otitis media and otosclerosis) were established in about half of the cases. Sensorineural hearing loss, other than age-related hearing loss and noise induced hearing loss, was diagnosed in 3.4% and 5.2% respectively. Severely impaired speech recognition, possibly reflecting age-related auditory neuropathy, was found in 0.4% in the "younger" group, and in 10% in the "older" group. Bilateral functional deafness was present in 3.2% of the 85-year-old persons, but was not present in the 70-75-year group. Conclusion: The incidence of probable age-related auditory neuropathy increases considerably from 70- 75 to 85 years. There are marked differences between "younger" and "older" elderly persons regarding hearing loss that severely affects oral communication.

The purpose of this study was to examine the quantitative properties of the FFR trends with an exponential curve-fitting model. Design : FFR trends obtained with increasing number of sweeps (up to 8000 sweeps) at three stimulus intensities (30, 45, and 60 dB nHL) were fit to an exponential model that consisted of estimates of background noise amplitude, asymptotic response amplitude, and a time constant. Five objective indices (Frequency Error, Slope Error, Tracking Accuracy, Pitch Strength and RMS Ratio) were used to represent different perspectives of pitch processing in the human brainstem. Study Sample : Twenty-three native speakers (16 males; age = 24.7 +/- 2.1 years) of Mandarin Chinese were recruited. Results : The results demonstrated that the exponential model provided a good fit (r(2) = 0.89 +/- 0.10) to the FFR trends with increasing number of sweeps for the five objective indices. Conclusions : The exponential model, combined with the five objective indices, can be used for difficult-to-test patients and may prove to be useful as an assessment and diagnostic method in both clinical and basic research efforts.

The purpose of this study was to establish a standardized procedure for clinical use in the measurement of the MLD Design : A newly developed computer software program using both an adaptive procedure (MLDA) and a Bekesy procedure (MLDB) was evaluated in this study. Study sample : Forty normal-hearing, native-English speaking adults between the ages of 18 and 26 years were included in the study. Results : Both the MLDA and MLDB procedures showed statistically significant sex differences in the masked thresholds used to obtain the MLD, but not for the calculated MLD value; hence, normative data need not be reported separately by sex. Furthermore, statistically significant differences between procedures were observed, with the MLDA procedure producing higher MLDs. The MLDA procedure permitted a d' analysis, which could not be determined using the MLDB procedure. For MLDA, d' = 1.4, test sensitivity = 96.4%, and test specificity = 60.3%. Conclusions: The results of this study indicate that MLDA is a more efficient testing procedure due to MLDA's higher MLD average and the statistical data available (d', and measures of sensitivity and specifi city).

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech recognition in noise; Linguistic complexity; Gottingen sentence test; Speech reception threshold ID SPEECH-INTELLIGIBILITY; WORKING-MEMORY; COMPREHENSION; APHASIA; NOISE; RECEPTION; HEARING; DISSOCIATION; THRESHOLD; LISTENERS AB Objective: We investigated if linguistic complexity contributes to the variation of the speech reception threshold in noise (SRTN) and thus should be employed as an additional design criterion in sentence tests used for audiometry. Design: Three test lists were established with sentences from the Gottingen sentence test (Kollmeier & Wesselkamp, 1997). One list contained linguistically simple sentences, the other two lists contained sentences with two types of linguistic complexity. For each listener the SRTN was determined for each list. Study Sample: Younger and older listeners with normal hearing and older listeners with hearing impairment were tested. Results: Younger listeners with normal hearing showed significantly worse SRTNs on the complex lists than on the simple list. This difference could not be found for either of the older groups. Conclusions: The effect of linguistic complexity on speech recognition seems to depend on age and/or hearing status. Hence, pending further research, linguistic complexity seems less relevant as a sentence test design criterion for clinical-audiological purposes, but we argue that a test with larger variation in linguistic complexity across sentences might show a relation between linguistic complexity and speech recognition even in a clinical population.

Design : BC thresholds were determined for 40 participants using the standardized P-3333 headband and a leather adjustable headstrap with variable static forces (2.4, 3.4, 4.4, 5.4 N). Comfort ratings were examined using a five-point Likert scale. Results : Mean BC thresholds were within +/- 2 dB across all conditions; differences may be considered small enough to be clinically insignificant. Participants experienced significantly greater discomfort with the P-3333 versus the adjustable headstrap. The mean static force of the P-3333 varied considerably and was higher in situ than the calibration standard of 5.4 N. Conclusions: The results suggest that future revisions of relevant international and national standards should address the use of an adjustable headstrap and a static force less than 5.4 N.

Design: VGD was measured using two talker sets with different inter-gender fundamental frequencies (F(0)), as well as different acoustic CI simulations. Vowel and consonant recognition in quiet and noise were also measured and compared with VGD performance. Study sample: Eleven postlingually deaf CI users. Results: The results showed that (1) mean VGD performance differed for different stimulus sets, (2) VGD and speech recognition performance varied among individual CI users, and (3) individual VGD performance was significantly correlated with speech recognition performance under certain conditions. Conclusions: VGD measured with selected stimulus sets might be useful for assessing not only pitch-related perception, but also spectral and temporal processing by individual CI users. In addition to improvements in spectral resolution and modulation detection, the improvement in higher modulation frequency discrimination might be particularly important for CI users in noisy environments.

Design: The development of the MQRTB involved three stages: (1) Selection of test items for the MQRTB; (2) Verification of its length and complexity with normally-hearing individuals; and (3) Pilot testing with CI recipients. Study Sample: Part 1 involved 65 adult listeners, Part 2 involved 10 normally-hearing adults, and Part 3 involved five adult MED-EL CI recipients. Results: The MQRTB consisted of ten songs, with ratings made on scales assessing pleasantness, naturalness, richness, fullness, sharpness, and roughness. Results of the pilot study, which compared FSP and HDCIS for music, indicated that acclimatization to a strategy had a significant effect on ratings (p < 0.05). When acclimatized to FSP, the group rated FSP as closer to ''exactly as I want it to sound'' than HDCIS (p < 0.05), and that HDCIS sounded significantly sharper and rougher than FSP. However when acclimatized to HDCIS, there were no significant differences between ratings. There was no effect of song familiarity or genre on ratings. Conclusions: Overall the results suggest that the use of FSP as the default strategy for MED-EL recipients would have a positive effect on music appreciation, and that the MQRTB is an effective tool for assessing music sound quality.

Design: We examined two groups of patients: women with epidural anesthesia underwent four tests of distortion product otoacoustic emissions(DPOAEs): on admission, and fifteen minutes, one hour, and three hours after the last epidural bolus of local anesthetic. Auditory brainstem response (ABR) tests were performed on admission, and one hour, and three hours after the last epidural bolus. Women who gave birth without epidural anesthesia underwent DPOAEs tests on admission, during a uterine contraction, during active delivery, and three hours after labor. ABR tests were performed on admission, during a uterine contraction, and three hours after labor Study sample: twenty patients participated in the study. Twelve gave birth with epidural anesthesia and eight without anesthesia. Results: No significant changes in DPOAEs and ABR recordings were found between the two groups. Conclusions: Epidural anesthesia does not impair the sensory or the neural elements of the hearing system and therefore does not influence hearing.

Design: Explorative analysis of the German tinnitus handicap inventory (THI-12) to assess potential sensitivity to tinnitus therapy in placebo-controlled randomized studies. Correlation analysis, including Cronbach's coefficient alpha alpha and explorative common factor analysis (EFA), was conducted within and between assessments to demonstrate the construct validity, dimensionality, and factorial structure of the THI-12. Study sample: N == 618 patients suffering from subjective tinnitus who were to be screened to participate in a randomized, placebo-controlled, 16-week, longitudinal study. Results: The THI-12 can reliably diagnose tinnitus-related impairments and disabilities and assess changes over time. The test--retest coefficient for neighboured visits was r > 0.69, the internal consistency of the THI-12 total score was alpha alpha <= 0.79 and alpha alpha <= 0.89 at subsequent visits. Predictability of THI-12 total score and overall variance increased with successive measurements. The three-factorial structure allowed for evaluation of factors that affect aspects of patients'' health-related quality of life. Conclusions: The THI-12, with its three-factorial structure, is a simple, reliable, and valid instrument for the diagnosis and assessment of tinnitus and associated impairment over time.

It was hypothesized that children with APD would demonstrate smaller changes. Design: Levels of DPOAEs were recorded for f(2) stimulus tones fixed at 2, 3, and 4 kHz while the f(1) tone was ramped around nominal stimulus frequency ratios of f(2)/f(1) == 1.22 and 1.10. Mean and maximum absolute changes resulting from contralateral broadband noise presented at 60 dB SPL were evaluated across the DPOAE frequency bands for each individual and for both groups of subjects. Study sample: Eight normal-hearing children and eight children with APD whose audiometric thresholds were normal participated. Results: There were no significant differences in DPOAE inhibition between normal hearing and APD groups, or previously recorded adult data. Mean absolute changes were typically near 1 dB, except for f(2) == 4 kHz and the stimulus frequency ratio 1.22 where inhibition was only 0.5 dB. However, there were individual children in both groups who demonstrated larger DPOAE changes for some stimulus parameters. Conclusions: The inhibition of otoacoustic emissions requires further study in APD children. C1 [Purcell, David W.] Univ Western Ontario, Elborn Coll, Natl Ctr Audiol, London, ON N6G 1H1, Canada.

Design: Two seven-step continua of synthetic CV syllables were constructed, with frication pole varied from /s/ to /integral a < .80). Results : The validity of the LSEQ was demonstrated by comparing the LSEQ scores to audiologic measures, responses on questionnaires, and to the scores for reference groups of younger and older listeners with normal hearing. Conclusion : The findings indicate that the LSEQ is a valid and reliable measure of listening self-efficacy with good potential for use in clinical and research settings.

Design : The English THI (THI-E) was translated into Hebrew by two bilingual investigators, independently. A third investigator then constructed the final Hebrew THI version (THI-H) from the two translations. This version was administered to fifty consecutive patients at the tinnitus clinic. Participants also assessed tinnitus severity and loudness, and completed the Hebrew versions of the Beck's depression inventory and the state anxiety inventory. Study Sample : The participants were fifty consecutive patients (older than 18 years of age, with a tinnitus lasting over three months) who were referred to a tinnitus clinic (none of them declared compensation seeking). Results : A very good internal consistency was found (alpha = 0.93), with significant correlation between the subscales of the THI-H and the Beck depression inventory score and the state anxiety inventory score. Conclusions : A valid and reliable THI-H questionnaire was constructed.

Design: Subjects were fitted binaurally with four directional microphone conditions (i.e., binaural omnidirectional, right asymmetric directional, left asymmetric directional and binaural directional microphones) using Siemens Intuis Directional behind-the-ear hearing aids. Speech understanding in noise was assessed using the Hearing in Noise Test, and acceptance of background noise was assessed using the Acceptable Noise Level procedure. Speech was presented from 0 degrees A degrees while noise was presented from 180 degrees A degrees azimuth. Results/Conclusions: The results revealed that speech understanding in noise improved when using asymmetric directional microphones compared to binaural omnidirectional microphone fittings and was not significantly hindered compared to binaural directional microphone fittings. The results also revealed that listeners accepted more background noise when fitted with asymmetric directional microphones as compared to binaural omnidirectional microphones. Lastly, the results revealed that the acceptance of noise was further increased for the binaural directional microphones when compared to the asymmetric directional microphones, maximizing listeners' willingness to accept background noise in the presence of noise. Clinical implications will be discussed. C1 [Bryan, Melinda Freyaldenhoven] Louisiana Tech Univ, Ruston, LA 71272 USA. [Kim, Jong S.] Yakima Valley Hearing & Speech Ctr, Yakima Valley, WA USA.

Design: We compared the HHIE-S score and the single question with audiometry results. By analysing the receiver operating characteristic (ROC) curves of the HHIE-S scores we estimated the appropriate cut-off points for the different degrees of hearing loss. Study Sample: 164 home-dwelling subjects in the age cohorts of 70, 75, 80 and 85 years in an industrialized town in Finland filled in the questionnaire, and attended the audiometry. Results: For the detection of moderate or worse hearing loss (i.e., pure tone average at 0.5-4 kHz frequencies > 40 dB), the HHIE-S cut-off score of > 8 had a sensitivity of 100% and a specificity of 59.7%. The single question had a sensitivity of 100% and a specificity of 70.7%. Thus, the single question was equally sensitive and more specific in detecting moderate or worse hearing loss than the HHIE-S score. However, for the detection of mild hearing loss (i.e., pure tone average > 25 dB), the HHIE-S was more sensitive but less specific than the single question.

TI Re-examining the relationship between audiometric profile and tinnitus pitch SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Audiogram; Audiometric edge; Correlation; Principal components; Multiple regression ID AUDITORY-CORTEX; HEARING-LOSS; PLASTICITY; MECHANISMS; AUDIOGRAM; SYSTEMS; CATS AB Objective: We explored the relationship between audiogram shape and tinnitus pitch to answer questions arising from neurophysiological models of tinnitus: ''Is the dominant tinnitus pitch associated with the edge of hearing loss?'' and ''Is such a relationship more robust in people with narrow tinnitus bandwidth or steep sloping hearing loss?'' Design: A broken-stick fitting objectively quantified slope, degree and edge of hearing loss up to 16 kHz. Tinnitus pitch was characterized up to 12 kHz. We used correlation and multiple regression analyses for examining relationships with many potentially predictive audiometric variables. Study Sample: 67 people with chronic bilateral tinnitus (43 men and 24 women, aged from 22 to 81 years). Results: In this ample of 67 subjects correlation failed to reveal any relationship between the tinnitus pitch and the edge frequency. The tinnitus pitch generally fell within the area of hearing loss. The pitch of the tinnitus in a subset of subjects with a narrow tinnitus bandwidth (n == 23) was associated with the audiometric edge. Conclusions: Our findings concerning subjects with narrow tinnitus bandwidth suggest that this can be used as an a priori inclusion criterion. A large group of such subjects should be tested to confirm these results.

TI Tinnitus and its risk factors in the Beaver Dam Offspring Study SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Tinnitus; Demographics/epidemiology; Hearing conservation; Aging ID BLUE MOUNTAINS HEARING; OLDER-ADULTS; PREVALENCE; IMPAIRMENT; ALCOHOL AB Objective: To assess the prevalence of tinnitus along with factors potentially associated with having tinnitus. Design: Data were from the Beaver Dam Offspring Study, an epidemiological cohort study of aging. Study Sample: After a personal interview and audiometric examination, participants (n == 3267, ages 21--84 years) were classified as having tinnitus if in the past year they reported having tinnitus of at least moderate severity or that caused difficulty in falling asleep. Results: The prevalence of tinnitus was 10.6%. In a multivariable logistic regression model adjusting for age and sex, the following factors were associated with having tinnitus: hearing impairment (Odds Ratio (OR) == 3.20), currently having a loud job (OR == 1.90), history of head injury (OR == 1.84), depressive symptoms (OR == 1.82), history of ear infection (men, OR == 1.75), history of target shooting (OR == 1.56), arthritis (OR == 1.46), and use of NSAID medications (OR == 1.33). For women, ever drinking alcohol in the past year was associated with a decreased risk of having tinnitus (OR == 0.56). Conclusions: These results suggest that tinnitus is a common symptom in this cohort and may be associated with some modifiable risk factors.

Design: Participants listened in quiet and with background babble to word triplets, evaluating whether the third word was related to the preceding words. A temporo-spatial principal component analysis was conducted on ERPs to the first and second words (S1 and S2), processed without an overt behavioral response. One factor corresponded to the N400 and revealed greater processing negativity for unrelated as compared to related S2s in quiet and in babble. Study sample: Twelve young adults with normal hearing. Results: Background babble had no significant impact on the N400 in the posterior region but increased neural processing negativity at anterior and central regions during the same timeframe. This differential processing negativity in babble occurred in response to S2 but not S1. Furthermore, background babble impacted processing negativity for related S2s more than unrelated S2s. Conclusions: Results suggest that speech processing in a modestly degraded listening environment alters neural activity associated with auditory working memory, attention, and semantic processing in anterior and central scalp regions.

Design: A convenience sampling method was used to identify and recruit subjects. The subjects completed a history form seeking demographic data, the APHAB-CH, and a questionnaire seeking a subjective rating of hearing aid performance and overall satisfaction with their hearing aid. Study Sample: The subjects were 134 experienced hearing aid users. Results: The APHAB-CH had a good internal consistency reliability estimate (alpha alpha == 0.85) comparable to that of the original version. Significant correlation was observed between the APHAB-CH scores and other subjective ratings for hearing aid performance and the overall satisfaction measure. A high test-retest reliability (intraclass correlation coefficient == 0.84) was observed. Confirmatory factor analysis revealed that the APHAB-CH had a two-factor structure comprising ""hearing disability"" and ""averviseness."" Normative data in terms of equal-percentile profiles were dervied for the APHAB-CH. Conclusion: The results suggest that the APHAB-CH is a reliable and valid measure of the outcomes of hearing aid fitting C1 Chinese Univ Hong Kong, Dept Otorhinolaryngol Head & Neck Surg, Hong Kong, Hong Kong, Peoples R China.

The development of auditory receptive skills and spoken language is often delayed in children who use cochlear implants, which may affect their appreciation of and responses to music. This in turn may be interpreted as disinterest in music. A questionnaire was developed to determine whether differences in exposure and responses to music exist between young cochlear implant recipients and their normally hearing peers. Design. The questionnaire was developed by a multidisciplinary team and distributed to parents of preschool children with normal hearing and to parents of preschool children who had been implanted at least one year prior. Study sample. The cochlear implant group comprised 23 children and was gender and age matched (within +/-+/- 2 months) to a group of children with normal hearing. Results & Conclusions. Young cochlear implant recipients receive similar exposure to audiovisual music media, parental singing and musical instruments at home. However, the data suggest that they receive less exposure to children's music presented without visual stimuli. Parents also reported less sophisticated responses to music for this group. The findings of this study have important implications concerning the provision of age-appropriate music habilitation materials and activities for young cochlear implant recipients.

The objective of the study was to determine the speech perception abilities for spectrally modified speech signals in individuals with auditory dys-synchrony. Study Sample. The speech identification scores of 30 normal hearing and 12 individuals diagnosed as having auditory dys-synchrony were studied. Design. Phonemically balanced words in Kannada developed by Yathiraj and Vijayalakshmi (2005) were presented unfiltered and filtered at 1700 Hz low-pass and 1700 Hz high-pass cut-off frequencies, and speech identification performance was assessed. Results. Results revealed that there is a highly significant difference in speech identification scores for unfiltered and low-pass filtered words. This difference could be attributed to the physiological coding deficits of low frequency information which are usually coded by phase locked responses in auditory nerve fibers (Sek & Moore, 1995). Conclusions. Thus, low-pass filtered words can be used as an effective tool to identify individuals with auditory dys-synchrony, especially those who have good speech identification scores in quiet.

Design: The P1-N1-P2 response to the onsets of stimuli (markers) defining a silent gap for within-channel (spectrally identical markers) and across-channel (spectrally different markers) conditions was examined using four perceptually-equated gap durations. Study Sample: A group of 24 older adults (mean age = 63 years) with normal hearing or minimal hearing loss participated. Results: Older adults exhibited neural activation patterns that were qualitatively different and more frontally oriented than those observed in a previous study (Lister et al., 2007) of younger listeners. Older adults showed longer P2 latencies and larger P1 amplitudes than younger adults, suggesting relatively slower neural travel time and altered auditory inhibition/arousal by irrelevant stimuli. Conclusion: Older adults appeared to recruit later-occurring T-complex-like generators for gap processing, compared to earlier-occurring T-complex-like generators by the younger group. Early and continued processing of channel cues with later processing of gap cues may represent the inefficiency of the aging auditory system and may contribute to poor speech understanding in noisy, real-world listening environments.

Conversely, it remains essentially undocumented whether hearing-aid users expected not to have occlusion-related problems experience own-voice issues. Design: To investigate this topic, a dedicated Own Voice Qualities (OVQ) questionnaire was developed and used in two experiments with stratified samples. Study Sample: In the main experiment, the OVQ was administered to 169 hearing-aid users (most of whom were expected not to have occlusion-related problems) and to a control group of 56 normally-hearing people. In the follow-up experiment, the OVQ was used in a cross-over study where 43 hearing-aid users rated own voice for an open fitting and a small-vent earmould fitting. Results: The results from the main experiment show that hearing-aid users (without occlusion) have more problems than the normal-hearing controls on several dimensions of own voice. The magnitude of these differences was found to be generally larger than the differences observed between the open fitting and the small-vent fitting in the follow-up experiment. Conclusions: This suggests that own voice is a potentially important concern, even for hearing-aid users who are not expected to have occlusion-related problems.

TI Implementation of a fast method for measuring psychophysical tuning curves SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Psychophysical tuning curves; Frequency selectivity; Dead regions ID FREQUENCY HEARING-LOSS; DEAD REGIONS; MASKING; THRESHOLD; COCHLEA; PERCEPTION; DIAGNOSIS; SPEECH; NOISE AB Objective: To implement a fast method for measuring psychophysical tuning curves (PTCs) for use in clinical applications, such as assessment of frequency selectivity and detection of dead regions in the cochlea. Design: The method is based on that described by Sek et al (2005) and has been implemented in software that can be run on a PC with a good-quality sound card. In addition to the main narrowband noise masker, a lowpass noise masker can be generated to prevent detection of a distortion band corresponding to the simple difference tone. Results: The software includes a routine for measuring the absolute threshold at the signal frequency and includes methods for estimating the frequency at the tip of the PTC. A PTC can typically be determined in about three minutes. A small amount of practice (two to three runs) may be required to achieve stable results. Conclusions: The software implementation allows PTCs to be measured quickly without a requirement for specialised equipment. C1 [Sek, Aleksander; Moore, Brian C.

TI Effects of speech signal content and speaker gender on acceptance of noise in listeners with normal hearing SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Acceptance of noise; Acceptable noise level; Most comfortable level; Speaker gender; Speech context ID BACKGROUND-NOISE; PRESENTATION LEVEL; PERCEPTION AB Objective: The purpose of this research was to determine if the content and/or speaker gender of a running speech sample affected the acceptance of background noise within a participant. Design: A male and a female recording of the Arizona Travelogue (Cosmos Inc.) and the ipsilateral competing message (ICM) from the synthetic sentence identification with ICM were created and used as the experimental speech signals. Two acceptable noise level measurements were obtained and averaged for each condition. Twenty-one participants rated interest level in the speech sample for each condition. Study Sample: Forty-three listeners with normal hearing participated. Results: Interest level was significantly greater for the ICM than the Arizona Travelogue speech samples, and was significantly greater for female samples. Neither the content of the sample nor the gender of the speaker significantly affected the most comfortable level or the acceptable noise level. Conclusions: Findings suggest that the acceptable noise level can be measured using various types of speech signals for normal-hearing listeners.

Gustav Weber, Jennifer Bellanova, Martina TI Clinical evaluation of a new hearing aid anti-cardioid directivity pattern SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aid; Directional; Anti-cardioid; Reverse cardioid ID PERFORMANCE AB Objective: The purpose of this research was to evaluate a new directional hearing aid algorithm which automatically adapts to an anti-cardioid pattern in background noise when a speech signal originates from behind the hearing aid user. Design: Using the hearing-in-noise-test (HINT) in the soundfield, with the sentences delivered adaptively from the back (180) and the standard HINT competing noise from the front (0; 72 dB SPL), the participants were tested for three different hearing aid conditions: omnidirectional, conventional adaptive directional, and adaptive directional with the anti-cardioid algorithm enabled. Study Sample: Adults (n = 21) with bilaterally symmetrical downward sloping sensorineural hearing loss; experienced hearing aid users and aided bilaterally for experimental testing. Results: Results revealed a significant effect for the hearing aid microphone setting (p < .0001), with a HINT mean RTS of 4.2 dB for conventional adaptive directional, -0.1 dB for omnidirectional, and -5.7 dB when the anti-cardioid algorithm was active. This was a large effect size (Cohen's f2). Conclusion: The findings suggest that the signal classification system steered the algorithm correctly, and that when implemented, the anti-cardioid polar pattern resulted in an improvement in speech recognition in background noise for this listening situation.

Design: Three programs differing in T-levels were created for ten subjects. Using the T-level setting that provided the lowest FM-tone, sound-field threshold levels for each subject, three additional programs were created with input dynamic range (IDR) settings of 50, 65 and 80 dB. Study Sample: Subjects were postlinguistically deaf adults implanted with either the Clarion CII or 90K CI devices. Results: Sound-field threshold levels were lowest with T-levels set higher than 10% of M-levels and with the two widest IDRs. Group data revealed significantly higher scores for CNC words presented at a soft level with an IDR of 80 dB and 65 dB compared to 50 dB. Although no significant group differences were seen between the three IDRs for sentences in noise, significant individual differences were present. Conclusions: Setting Ts higher than the manufacturer's recommendation of 10% of M-levels and providing IDR options can improve overall speech perception; however, for some users, higher Ts and wider IDRs may not be appropriate. Based on the results of the study, clinical programming recommendations are provided.

Design: A lexical tone perception test and a pitch interval discrimination test were administered to a group of CI users and a group of normal-hearing (NH) listeners. Sample study: Nineteen adult CI users and 10 NH listeners who are native-Mandarin-Chinese speakers participated in the study. Result: Tone-perception performance of the CI group was, on average, 58.3% correct (+/- 19.78% correct), and performance of the NH group was near perfect. The CI group had a mean threshold of 5.66 semitones (+/- 5.57 semitones) in pitch discrimination as compared to the threshold of 0.44 semitone from the NH group. There was a strong correlation between the CI users' tone-perception performance and their pitch discrimination threshold (r = -0.75, p < 0.001). Conclution: Musical and lexical pitch perceptions are strongly correlated with each other and they might share similar mechanisms in electric hearing.

Study Sample: Twenty experienced adult CI users participated in the study in connection with upgrading to a new speech processor and at a two-year follow-up. Design: Blinded paired-comparisons between FSP and HDCIS were performed for speech intelligibility and music sound quality. Standard speech recognition tests in quiet and in noise were also accomplished to monitor the participants' actual performance and to evaluate long-term outcomes. Results: Overall, the paired-comparison results showed no significant differences between the strategies, however, the total numbers of significant individual preferences were: 11 FSP vs. 12 HDCIS for speech, and 4 FSP vs. 15 HDCIS for music. The average speech recognition score decreased significantly after one month with FSP, but after two years there were no significant difference compared to the initial results with CIS+. Conclusions: Owing to the large individual differences in subjective preference, and the fact that the FSP strategy was not superior to the CIS variations, the recipients should be given the opportunity of choosing between the strategies C1 [Magnusson, Lennart] Univ Gothenburg, Sahlgrenska Univ Hosp, Dept Audiol, S-41345 Gothenburg, Sweden.

Ensemble directors of public school and college bands, orchestras, and choirs, are unaware and unprepared to recognize and manage risk from excessive sound exposures. Schools of music and conservatories around the world, and the organizations that accredit them, need to embrace the idea that schools of music are best suited to facilitate change, conduct research, create and impart knowledge, institute competency, and most importantly, cultivate a culture of responsibility and accountability throughout the music discipline. By drawing attention to actions pursued at and through the College of Music at the University of North Texas, the purpose of this paper is to encourage change and to assist others in efforts to reach the best conditions for preventing irreversible hearing disorders associated with music.

However, commonly-used audiometric databases either do not take these differences into account, or account for them using data not easily generalized to the US population. The objective of this study was to obtain distributions that are generalizable to the US population without significant history of exposure to occupational noise. Cumulative pure tone threshold distributions from the National Health and Nutrition Examination Survey (NHANES) III and the 1999-2004 data from the continuous NHANES were fitted with an asymmetric sigmoid function with reverse asymmetry, by gender, ethnicity, age, ear, and the stimulus frequency. Results indicated that conditional distributions based on these factors are warranted. Percentiles on the cumulative distribution functions can be transformed into standard normal variates (i.e. z-scores) to facilitate combination of results over time or across individuals with different demographic characteristics. However, combinations across frequency could obscure meaningful differences between the reference group and the hearing test results under analysis.

Monroe, Tim Drambarean, Viorel TI Better protection from blasts without sacrificing situational awareness SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Head motion; Localization; Situational awareness; Transparent blast plug earplugs ID SPECTRAL CUES; HEARING-LOSS; SOUND; LOCALIZATION; PLANE AB A large number of soldiers returning from war report hearing loss and/or tinnitus. Many deployed soldiers decline to wear their hearing protection devices (HPDs) because they feel that earplugs interfere with their ability to detect and localize the enemy and their friends. The detection problem is easily handled in electronic devices with low-noise microphones. The localization problem is not as easy. In this paper, the factors that reduce situational awareness - hearing loss and restricted bandwidth in HPD devices - are discussed in light of available data, followed by a review of the cues to localization. Two electronic blast plug earplugs with 16-kHz bandwidth are described. Both provide subjectively transparent sound with regard to sound quality and localization, i.e., they sound almost as if nothing is in the ears, while protecting the ears from blasts. Finally, two formal experiments are described which investigated localization performance compared to popular existing military HPDs and the open ear. The tested earplugs performed well regarding maintaining situational awareness. Detection-distance and acceptance studies are underway.

A three-pronged intervention to increase HPD use was conducted among construction workers and included a baseline hearing loss prevention training, follow-up ''toolbox'' (TB) reinforcement trainings, and use of a personal noise level indicator (NLI). A total of 176 subjects on eight sites completed three assessments. Prior to intervention, HPDs were used an average of 34.5% of the time and increased significantly, up about 12.1% after intervention and 7.5% two months after interventions were completed. The increase in HPD use was greatest among the group receiving both TB and NLI interventions; up about 25% from baseline, and this group was about two times more likely to use HPDs than the BL (baseline) training only group. This study demonstrates the mild impact of a well-constructed HPD use training and provides support for the additional use of a personal NLI to increase use of HPDs among construction workers. The most effective procedures for using such instruments require further exploration.

Study sample and Design: We used the ""Strengths and Difficulties Questionnaire"" (SDQ) to assess the mental health problems of 32 adolescents with CI (mean age 15.0 years) and 212 normal hearing peers (mean age 15.0 years). Results: Parent and teacher ratings for the CI subjects (ES emotional symptoms, HA inattention-hyperactivity, CP conduct-problems and PBS pro-social behavior) did not differ significantly from the results of normal hearing peers. However, teachers rated significantly more cases as having peer problems (PP) and more cases as having very high (clinical) total difficulty scores (TDS) in the CI group. The SDQ results of the CI users correlated significantly with poor results in auditory performance and special school education. The age at CI implantation was not found to be a correlated with emotional, behavioral and social problems. Conclusions: Our findings indicate that the mental health of deaf adolescents with CI is comparable to that of normal hearing peers.

TI Development of a Mandarin tone identification test: Sensitivity index d ' as a performance measure for individual tones SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Speech reception threshold; Mandarin; Tone language; Tone identification; Detection theory; Performance-intensity function; Sensitivity ID PSYCHOMETRIC FUNCTION; NOISE TEST; COCHLEAR IMPLANTS; MATERIALS SPOKEN; SPEECH; HEARING; RECOGNITION; INFORMATION; PERCEPTION; ENVELOPE AB Objective: The aim of this study was to develop comprehensive test material for Mandarin tone identification in noise for a male and a female talker. Additionally, the sensitivity index d' as a measure for the listeners' performance to identify individual tones was evaluated. Design: The study followed a prospective design. Study sample: The complete material comprises 72 loudness-balanced syllables in all 4 Mandarin tones. For a selection of 20 syllables, i.e. 80 test words, performance-versus-intensity functions were measured in spectrally matched noise for 16 normal-hearing participants. Results: The average speech reception thresholds in noise were --12.9 dB for the male and --13.6 dB for the female talker recordings. The corresponding slopes were 8.6%/dB and 7.3%/dB. As a performance measure for individual tones, the proportion of correct responses to specific tones was substantially contaminated by response bias. The sensitivity index d', calculated according to detection theory, provided reasonable and unbiased performance versus intensity functions. Conclusions: The results firstly indicate that the material is homogenous enough for use as a speech test in clinical work and research. Secondly, to assess the discrimination performance for individual tones, d' values outperform the simple proportion of correct responses.

Design: Commercial hearing aids with a microphone placed in-the-ear-canal (ITC), behind-the-ear (BTE), and in-the-pinna (ITP) were evaluated in the frontal and full horizontal plane, and in the frontal vertical plane. Study Sample: A group of 13 hearing-impaired subjects evaluated the hearing aids. Nine normal-hearing listeners were used as a reference group. Results and Conclusions: Differences in sound localization in the front-back dimension were found for different hearing aids. A large inter-subject variability was found during the front-back and elevation experiments. With ITP or ITC microphones, almost all natural spectral information was preserved. One of the BTE hearing aids, which is equipped with a directional microphone configuration, generated a sufficient amount of spectral cues to allow front-back discrimination. No significant effect of hearing aids on elevation performance in the frontal vertical plane was observed. Hearing-impaired subjects reached the same performance with and without the different hearing aids. In the unaided condition, a frequency-specific audibility correction was applied. Some of the hearing-impaired listeners reached normal hearing performance with this correction.

Design: Music quality was assessed using a rating scale for three types of music: orchestral classical music, jazz instrumental, and a female vocalist. The music stimuli were subjected to a wide range of simulated hearing aid processing conditions including, (1) noise and nonlinear processing, (2) linear filtering, and (3) combinations of noise, nonlinear, and linear filtering. Study sample: Quality ratings were measured in a group of 19 listeners with normal hearing and a group of 15 listeners with sensorineural hearing impairment. Results: Quality ratings in both groups were generally comparable, were reliable across test sessions, were impacted more by noise and nonlinear signal processing than by linear filtering, and were significantly affected by the genre of music. Conclusions: The average quality ratings for music were reasonably well predicted by the hearing aid speech quality index (HASQI), but additional work is needed to optimize the index to the wide range of music genres and processing conditions included in this study.

Study Sample: Commonly used bisyllabic and trisyllabic Cantonese words were digitally recorded by native male and female talkers and then evaluated by twenty normal-hearing Cantonese listeners. Design: The recorded bisyllabic words were psychometrically evaluated and arranged into four WR lists and eight half-lists that are relatively homogeneous in audibility. Using logistic regression, SRT materials were developed by selecting 28 trisyllabic words with relatively steep psychometric functions and digitally adjusting their intensity to match the listeners'' mean pure-tone average. Result: The mean psychometric slopes for the WR materials were 7.5%/dB for the male talker and 7.6%/dB for the female talker, with no statistically significant differences between the lists or half-lists. At intensity levels required for 50% intelligibility, the mean psychometric slopes of the male and female talker SRT materials were 14.5%/dB and 14.9 %/dB, respectively. Conclusion: High-quality digital recordings of Cantonese speech audiometric WR and SRT materials were developed and validated in this study. These materials are available on compact disc, indexed by talker gender. C1 [Nissen, Shawn L.] Brigham Young Univ, Dept Commun Disorders, Provo, UT 84602 USA.

The speech material originated from Nielsen & Dau (2009) where a sentence-based intelligibility equalization method was presented. Design: In the present study, the speech material was evaluated for naturalness and a subset of sentences selected. The new sentence lists were validated, and after three weeks retested. An additional experiment investigated how recollection of sentences affected the listeners'' performance. Study sample: 16 NH and 16 HI listeners participated in the validation and retest. Twelve HI listeners participated in the experiment on recollection. Results: The average speech recognition threshold in noise (SRT(N)) for the NH listeners was --2.52 dB, with an overall standard deviation of 0.87 dB. The within-subject standard deviation was similar for the NH and the HI listeners. In the retest, the SRT(N) decreased by 0.4 dB in both groups. Conclusions: The Danish HINT consists of 10 test lists and three practice lists each containing 20 sentences. The validation results are comparable to those of other versions of HINT. The test seems equally reliable for NH and HI listeners. After three weeks, reliable results can be obtained when sentence lists are reused with the same listeners.

NIHL is the most prevalent and preventable occupational disease in most Asian countries. Sources of noise in these countries include manufacturing and agriculture industries, exploitation of natural resources, and urban traffic. The highest attributable fraction of adult-onset hearing loss resulting from noise exposure in the world comes from Asian countries. NIHL is a serious health problem in Asia, not only because of the number of affected labourers, but also because the majority of Asian countries are still developing economies where access to health services and preventive programmes are limited. Lack of awareness about NIHL among employers, employees, and health care professionals is one of the main barriers for the prevention of NIHL in Asia. In this paper, the sources of noise, NIHL prevalence in different industries, local legislation, and research publications on NIHL from Asia are discussed.

All subjects reported normal hearing during telephone interviews, yet not all subjects had normal sensitivity as defined by well-accepted criteria. At one or more test frequencies (0.25--8 kHz), 7% of ears had thresholds >= 25 dB HL and 12% had thresholds >= 20 dB HL. The proportion of ears with abnormal findings decreased when three-frequency pure-tone-averages were used. Low-frequency PTA hearing loss was detected in 2.7% of ears and high-frequency PTA hearing loss was detected in 7.1% of ears; however, there was little evidence for ''notched'' audiograms. There was a statistically reliable relationship in which personal music player use was correlated with decreased hearing status in male subjects. Routine screening and education regarding hearing loss risk factors are critical as college students do not always self-identify early changes in hearing. Large-scale systematic investigations of college students'' hearing status appear to be warranted; the current sample size was not adequate to precisely measure potential contributions of different sound sources to the elevated thresholds measured in some subjects.

Design: The study employed a counterbalanced design. Three lists of monosyllabic English and bisyllabic Spanish words (50 words per list per language) were presented in two blocks. For each block, word lists were presented in quiet and at +6 and 0 dB SNR. Listeners repeated each word in verbal and written forms. At the end of the experiment, they rated the familiarity of the test words on a seven-point scale. Study Sample: Twenty English-dominant (ED) and 22 Spanish-dominant (SD) normal-hearing adult listeners participated in the study. Results: Most test words, English or Spanish, were familiar to the listeners. However, ED listeners were less familiar with Spanish than English words, whereas SD listeners were less familiar with English than Spanish words. Contribution of word familiarity to word recognition remained largely constant across listening conditions for both English and Spanish tests. Conclusions: Despite high familiarity of most test words, clinicians should be aware of the residual effects of familiarity on the English word test even after most unfamiliar words are removed, regardless of clients' language dominance.

Design: A collection of sentences was developed, rated for naturalness and grammatical complexity, and digitally recorded using a female speaker. Sentences found to have similar psychometric curve slopes, with equivalent intelligibility at three different noise levels, were arranged into 22 phonemically matched lists of ten sentences each. List equivalence was evaluated in normal-hearing listeners in full and reduced bandwidth conditions. Test-retest reliability of the remaining lists was evaluated in a second group of listeners. Study Sample: All listeners were native speakers of Afrikaans with normal hearing. For evaluation of list equivalence, ten listeners were used. Twenty other listeners were used to evaluate test-retest reliability. Results: A collection of eighteen phonemically matched lists was produced. Lists were found to be of equivalent difficulty in full and reduced bandwidth conditions, and to have good test-retest reliability in normal-hearing listeners. The average recognition threshold of these lists was -2.73 dB signal-to-noise ratio (standard deviation = 0.64 dB), and within-subject variability was 1.22 dB. Conclusions: The developed test provides a valid and reliable means of measuring sentence recognition thresholds in noise in Afrikaans.

The secondary purpose was to investigate the relationships among ASSRs, word recognition in quiet, and word recognition in babble. Design: ASSRs were elicited by a complex mixed-modulation tonal stimulus (carrier frequencies of 500, 1500, 2500, and 4000 Hz; modulation rate of 40 or 90 Hz) presented in quiet and in babble. The level of each carrier frequency was adjusted to match the level of the multitalker babble spectrum, which was based on the long term speech spectrum average. Word recognition in noise (WIN) performance was measured and correlated to ASSR amplitude and ASSR detection rate. Study Sample: Nineteen normal-hearing adults and nineteen adults with sensorineural hearing loss were recruited. Results and Conclusions: The presence of babble significantly reduced the ASSR detection rate and ASSR amplitude for NH subjects, but had minimal effect on ASSRs for HI subjects. In addition, babble enhanced ASSR amplitude at high stimulus levels. ASSR detection rate and ASSR amplitude recorded in quiet and babble were significantly correlated with word recognition performance for NH and HI subjects.

It was previously found that the children's version (the SCAN-C) over diagnoses auditory processing disorder in UK children. This study was conducted to assess the use of the SCAN-A with UK adults. Design: Comparison of UK adult's SCAN-A performance to US-based normative data. Study Sample: 31 UK adults aged 19 to 64 years (M 24, sd 10). Results: The UK sample scored significantly worse on three subtests: the Filtered Words (FW), Competing Words (CW) and Competing Sentences (CS) sections as well as on the Total Score. Conclusions: Applying US norms to UK adult's performance results in a high rate of over-identification of listening difficulties. Alternative UK norms are provided and implications for use of the SCAN-A with UK adolescents and adults are discussed.

Consequently, the incidence of hearing loss is not well established. Objective: To document the incidence of hearing loss in cystic fibrosis (CF) children. Design: Hearing function of 45 children from Great Ormond Street Hospital was assessed using pure-tone audiometry up to 20kHz and DPOAEs up to 8kHz. Study Sample: 39/45 of participants had received intravenous (IV) AGs, 23 of which received repeated IV AGs every 3 months. Results: In this high exposure group, 8 (21%) had clear signs of ototoxicity; average 8-20kHz thresholds were elevated by similar to 50dB and DPOAE amplitudes were >10dB lower at f2 3.2-6.3 kHz. The remaining 31/39 (79%) of AG exposed patients had normal, even exceptionally good hearing. The 21% incidence of ototoxicity we observed is substantial and higher than previously reported. However, our finding of normal hearing in children with equal AG exposure strongly suggests that other unknown factors, possibly genetic susceptibility, influence this outcome. Conclusions: We recommend comparable auditory testing in all CF patients with high AG exposures. Genetic analysis may help explain the dichotomy in response to AGs found.

GJB2 mutations are responsible for more than half of all cases of prelingual nonsyndromic recessive deafness in Caucasians, representing the most important deafness-causing factor in the industrialized world. Other genes such as MTRNR1 are also involved. In sub-Saharan Africa, environmental factors seem to dominate genetic contributions, but few studies on the etiology of deafness in Africa are available for comparison. Design: prospective cross sectional study. Study Sample: we performed a molecular screen of the GJB2 and MTRNR1 genes in 70 deaf children and 67 unaffected controls in Maroua (Cameroon) and a literature analysis focused on deafness epidemiology in developing countries. Results: no GJB2 mutations emerged, and only a single MTRNR1 variant that may be pathogenic was found. Conclusion: environmental factors turn out to be more relevant than genetic factor in the Maroua population.

Very little attention has been paid in the literature to quality of life (QoL), psychosocial consequences and audiological rehabilitation after SSHL. Design: We studied how level of hearing loss, hearing recovery, tinnitus and vertigo affect QoL after SSHL and the psychosocial consequences of SSHL in terms of sick leave. Furthermore, the audiological rehabilitation given to patients in connection with SSHL and the benefit of the rehabilitation were studied. Study Sample: Three hundred and sixty-nine (369) patients with SSHL were analysed in the present study. Results: Annoying tinnitus and remaining vertigo after SSHL were the strongest predictors of negative effects on QoL. Conclusions: The study indicates that patients with SSHL require extended audiological rehabilitation including a multi-disciplinary rehabilitation approach (medical, social and psychological) to cope with the complex issues that can arise after SSHL.

Auditory neuropathy spectrum disorder (ANSD) affects approximately 10% of patients with sensorineural hearing loss. While many studies report abnormalities at the level of the cochlea, auditory nerve, and brainstem in children with ANSD, much less is known about their cortical development. We examined central auditory maturation in 21 children with ANSD. Design. Morphology, latency and amplitude of the P1 cortical auditory evoked potential (CAEP) were used to assess auditory cortical maturation. Children's scores on a measure of auditory skill development (IT-MAIS) were correlated with CAEPs. Study Sample. Participants were 21 children with ANSD. All were hearing aid users. Result. Children with ANSD exhibited differences in central auditory maturation. Overall, two-thirds of children revealed present P1 CAEP responses. Of these, just over one third (38%) showed normal P1 response morphology, latency and amplitude, while another third (33%) showed delayed P1 response latencies and significantly smaller amplitudes. The remaining children (29%) revealed abnormal or absent P1 responses. Overall, P1 responses were significantly correlated with auditory skill development. Conclusion: Our results suggest that P1 CAEP responses may be: (i) A useful indicator of the extent to which neural dys-synchrony disrupts cortical development, (ii) A good predictor of behavioral outcome in children with ANSD.

Design: A repeated ABCD experimental design for the four rate conditions was employed. A sinusoidally amplitude modulated acoustic signal was presented to the audio input of a research processor. Stimuli were presented at an acoustic level that produced electrical levels close to the subjects' most comfortable level (MCL) of stimulation and at an acoustic level 20 dB below this. Study Sample: Ten postlingually deaf adult users of the Nucleus CI24 cochlear implant participated. Results: Acoustic modulation detection thresholds (MDTs), averaged across the subject group, were significantly better for rates of 500 pps/ch compared to the other rates examined for stimuli presented at MCL. In addition, there was a significant relation between speech perception in noise and acoustic MDTs at MCL. Conclusions: The benefits obtained in speech perception and modulation detection as a function of rate were attributed to an increased electrical dynamic range as a function of stimulation rate, at least for rates up to 500 pps/ch.

Design: Seven different masker types with Dutch speech materials were evaluated. Amongst these maskers were the ICRA-5 fluctuating noise, the international speech test signal (ISTS), and competing talkers in Dutch and Swedish. Study Sample: Normal-hearing and hearing-impaired subjects. Results: The normal-hearing subjects benefited from both temporal gaps and temporal fine structure in the fluctuating maskers. When the competing talker was comprehensible, performance decreased. The ISTS masker appeared to cause a large informational masking component. The stationary maskers yielded the steepest slopes of the psychometric function, followed by the modulated noises, followed by the competing talkers. Although the hearing-impaired group was heterogeneous, their data showed similar tendencies, but sometimes to a lesser extent, depending on individuals' hearing impairment. Conclusions: If measurement time is of primary concern non-modulated maskers are advised. If it is useful to assess release of masking by the use of temporal gaps, a fluctuating noise is advised. If perception of temporal fine structure is being investigated, a foreign-language competing talker is advised.

Voice pitch carries important cues for speech perception in humans. Recent studies have shown the feasibility of recording the frequency-following response (FFR) to voice pitch in normal-hearing listeners. The presence of such a response, however, has been dependent on subjective interpretation of experimenters. The purpose of this study was to develop and test an automated procedure including a control-experimental protocol and response-threshold criteria suitable for extracting FFRs to voice pitch, and compare the results to human judgments. Design. A set of four Mandarin tones (Tone 1 flat; Tone 2 rising; Tone 3 dipping; and Tone 4 falling) were prepared to reflect the four contrastive pitch contours. Two distinctive algorithms, short-term autocorrelation in the time domain and narrow-band spectrogram in the frequency domain, were used to estimate the Frequency Error, Slope Error, Tracking Accuracy, Pitch Strength and Pitch-Noise Ratio of the recordings from individual listeners as well as the power and false-positive rates of each algorithm. Study Sample. Eleven native speakers (five males; age: mean +/- SD = 31.4 +/- 4.7 years) of Mandarin Chinese were recruited. Results. The results demonstrated that both algorithms were suitable for extracting FFRs and the objective measures showed comparable results to human judgments. Conclusions. The automated procedure used in this study, including the use of the control-experimental protocol and response thresholds used for each of the five objective indices, can be used for difficult-to-test patients and may prove to be useful as an assessment and diagnostic method in both clinical and basic research efforts.

TI Speech understanding in noise with an eyeglass hearing aid: Asymmetric fitting and the head shadow benefit of anterior microphones SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory disorder; Hearing; Human; Treatment; Prosthesis; Hearing aid; Directional microphone; Dual microphone; Outcomes ID DIRECTIONAL BENEFIT; RECEPTION THRESHOLD; IMPAIRED LISTENERS; ARRAY; LEVEL AB Objective: To test speech understanding in noise using array microphones integrated in an eyeglass device and to test if microphones placed anteriorly at the temple provide better directivity than above the pinna. Design: Sentences were presented from the front and uncorrelated noise from 45, 135, 225 and 315 degrees. Study Sample: Fifteen hearing impaired participants with a significant speech discrimination loss were included, as well as 5 normal hearing listeners. Results: The device (Varibel) improved speech understanding in noise compared to most conventional directional devices with a directional benefit of 5.3 dB in the asymmetric fit mode, which was not significantly different from the bilateral fully directional mode (6.3 dB). Anterior microphones outperformed microphones at a conventional position above the pinna by 2.6 dB. Conclusions: By integrating microphones in an eyeglass frame, a long array can be used resulting in a higher directionality index and improved speech understanding in noise. An asymmetric fit did not significantly reduce performance and can be considered to increase acceptance and environmental awareness. Directional microphones at the temple seemed to profit more from the head shadow than above the pinna, better suppressing noise from behind the listener. C1 [Mens, Lucas H.

Design: The SII of meaningful and nonsense sentences were held constant for each of three bandwidths to test the hypothesis that perception would be equivalent in each condition. The sentences were filtered to produce three bandwidth conditions (low-pass cut-off frequency: 0.8, 1.25, 2.5 kHz) and the sensation level within each bandwidth was adjusted to produce a similar SII (0.43-0.48). Sentences were presented in broadband noise to facilitate equivalent audibility across subjects in each bandwidth condition. Study sample: Participants were 20 adults between the ages of 19 and 47 years and 20 eight-year-old children. All participants had normal hearing. Results and conclusion: Contrary to the hypothesis, performance of both groups increased significantly as bandwidth increased. Significant main effects of group and sentence type were also found. These results indicate that performance was governed largely by the bandwidth of the stimuli and that those effects were not represented well in the SII.

This study investigated the ability of AN subjects to perceive temporally modified consonant-vowel (CV) pairs and shed light on their phonological awareness skills. Design: Four Arabic CV pairs were selected: /ki/-/gi/, /to/-/do/, /si/-/sti/ and /so/-/zo/. The formant transitions in consonants and the pauses between CV pairs were prolonged. Rhyming, segmentation and blending skills were tested using words at a natural rate of speech and with prolongation of the speech stream. Study sample: Fourteen adult AN subjects were compared to a matched group of cochlear-impaired patients in their perception of acoustically processed speech. Results: The AN group distinguished the CV pairs at a low speech rate, in particular with modification of the consonant duration. Phonological awareness skills deteriorated in adult AN subjects but improved with prolongation of the speech inter-syllabic time interval. Conclusions: A rehabilitation program for AN should consider temporal modification of speech, training for auditory temporal processing and the use of devices with innovative signal processing schemes. Verbal modifications as well as visual imaging appear to be promising compensatory strategies for remediating the affected phonological processing skills.

This report describes the application of the software tool "Fitting to Outcomes eXpert" (FOX) in programming the cochlear implant (CI) processor in new users. FOX is an intelligent agent to assist in the programming of CI processors. The concept of FOX is to modify maps on the basis of specific outcome measures, achieved using heuristic logic and based on a set of deterministic "rules". Design. A prospective study was conducted on eight consecutive CI-users with a follow-up of three months. Study Sample. Eight adult subjects with postlingual deafness were implanted with the Advanced Bionics HiRes90k device. The implants were programmed using FOX, running a set of rules known as Eargroup's EG0910 advice, which features a set of "automaps". The protocol employed for the initial 3 months is presented, with description of the map modifications generated by FOX and the corresponding psychoacoustic test results. Results. The 3 month median results show 25 dBHL as PTA, 77% (55 dBSPL) and 71% (70 dBSPL) phoneme score at speech audiometry and loudness scaling in or near to the normal zone at different frequencies.

Study sample: Subjects consisted of 20 adults (40 ears) with normal hearing sensitivity. Design: Puretone thresholds (PTs) were obtained in 2 dB steps at each octave band. The newly developed Korean bisyllabic words were used to establish the speech recognition thresholds (SRTs). The SRT was the level at 50% correct responses based on the psychometric function performed from -8 dB HL (12 dB SPL) up to the level at or above 90% correct responses in 2 dB steps. Results Conclusions: The mean SRT was 23.44 dB SPL for sets comprised of 36 Korean bisyllabic words. Thus, the difference between English and Korean RSRTLs was about 3.44 dB. We recommend further study to recalculate the RSRTL for Korean speech audiometry with more subjects.

This study investigated the validity and reliability of in-situ air conduction hearing thresholds measured with closed and open domes relative to thresholds measured with insert earphones, and explored sources of variability in the measures. Twenty-four adults with sensorineural hearing impairment attended two sessions in which thresholds and real-ear-to-dial-difference (REDD) values were measured. Without correction, significantly higher low-frequency thresholds in dB HL were measured in-situ than with insert earphones. Differences were due predominantly to differences in ear canal SPL, as measured with the REDD, which were attributed to leaking low-frequency energy. Test-retest data yielded higher variability with the closed dome coupling due to inconsistent seals achieved with this tip. For all three conditions, inter-participant variability in the REDD values was greater than intra-participant variability. Overall, in-situ audiometry is as valid and reliable as conventional audiometry provided appropriate REDD corrections are made and ambient sound in the test environment is controlled.

The aim of this study was to evaluate how these 'missing patients' feel and whether they still use their sound generators after they discontinue retraining therapy. We interviewed 269 tinnitus patients by phone who never returned to the clinic after receiving initial counseling and a generator for sound enrichment. Twenty-six percent did not have tinnitus anymore, 30.5% still used the sound generator to treat their tinnitus, and 43.5% did not use their sound generator but still suffered from tinnitus. This study suggests that therapists need to contact missing patients periodically to follow their improvement, encourage them, and decide on new therapeutic approaches as necessary.

A distinction was made between hearing-related and other health care contacts. Data were collected at the baseline measurement of the national longitudinal study on hearing, and at each month during a subsequent period of six months. Hearing status was determined using an internet speech-in-noise test. The sample comprised 1295 normally-hearing and hearing-impaired subjects, aged 18-65 years. Adjusting for confounders, regression models showed that hearing-impaired respondents had significantly more contacts and higher costs for primary, secondary, and occupational care than normally-hearing respondents during the period under investigation. The differences were due to a larger number of health care contacts for which hearing impairment was the main motive to seek help. After excluding these contacts, the differences in health care use and costs between the groups were not significant. This suggests that besides hearing-related contacts, adults with hearing impairment do not make more use of health care resources than adults without hearing difficulties.

Existing artificial signals do not adequately fulfill these requirements. Moreover, recordings from natural speakers represent only one language and are therefore not internationally acceptable. For this reason, an International Speech Test Signal (ISTS) was developed. It is based on natural recordings but is largely non-intelligible because of segmentation and remixing. When using the signal for hearing aid measurements, the gain of a device can be described at different percentiles of the speech level distribution. The primary intention is to include this test signal with a new measurement method for a new hearing aid standard (IEC 60118-15).

This study compared the effects of reduced visual acuity on auditory-visual (AV) speech-recognition in noise among younger and older adults. Two groups of participants performed a closed-set sentence-recognition task in one auditory-alone (A-alone) condition and under three AV conditions: normal visual acuity (6/6), and with blurred vision to simulate a 6/30 and 6/60 visual impairment. The results showed that (1) the addition of visual speech cues improved speech-perception relative to the A-alone condition, (2) under the AV conditions, performance declined as the amount of blurring increased, (3) even under the AV condition that simulated a visual acuity of 6/60, the speech recognition scores were significantly higher than those obtained under the A-alone condition, and (4) generally, younger adults obtained higher scores than older adults under all conditions. Our results demonstrate the benefits of visual cues to enhance speech understanding even when visual acuity is not optimal.

TI Combining acoustic and electric stimulation in the service of speech recognition SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implants; Combined acoustic and electric stimulation; Bilateral cochlear implants ID BILATERAL COCHLEAR IMPLANTATION; USE HEARING-AIDS; FUNDAMENTAL-FREQUENCY; AUDITORY-SYSTEM; OPPOSITE EARS; PERCEPTION; NOISE; ADULTS; BENEFITS; CONJUNCTION AB The majority of recently implanted, cochlear implant patients can potentially benefit from a hearing aid in the ear contralateral to the implant. When patients combine electric and acoustic stimulation, word recognition in quiet and sentence recognition in noise increase significantly. Several studies suggest that the acoustic information that leads to the increased level of performance resides mostly in the frequency region of the voice fundamental, e. g. 125 Hz for a male voice. Recent studies suggest that this information aids speech recognition in noise by improving the recognition of lexical boundaries or word onsets. In some noise environments, patients with bilateral implants can achieve similar levels of performance as patients who combine electric and acoustic stimulation. Patients who have undergone hearing preservation surgery, and who have electric stimulation from a cochlear implant and who have low-frequency hearing in both the implanted and not-implanted ears, achieve the best performance in a high noise environment.

The objective of this study was to investigate the prevalence of HI and possible differences between ears in older adults. The subjects (n = 850), aged 54-66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed. Another questionnaire was mailed to collect information on non-participants. The prevalence of HI averaged over the frequencies of 0.5, 1, 2, and 4 kHz for the better ear >= 20 dB HL was 26.7% (men: 36.8%, women: 18.4%). There was no difference between left and right ear pure-tone averages over the frequencies 0.5, 1, 2, and 4 kHz (PTA (0.5-4 kHz)), but a significant difference of -0.8 dB HL was found for the low frequencies 0.125, 0.25, and 0.5 kHz (PTA (0.125-0.5 kHz)), and 4.4 dB HL for the high frequencies over 4, 6, and 8 kHz (PTA (4-8 kHz)). In conclusion, HI was a highly prevalent finding in this age group. C1 [Hannula, Samuli; Maki-Torkko, Elina; Majamaa, Kari; Sorri, Martti] Univ Oulu, Dept Clin Med, FIN-90014 Oulu, Finland.

Listening effort was measured using a dual task paradigm. Participants repeated monosyllabic words presented in a background of children's chatter (primary task) at SNRs that are considered typical of the school classroom environment (quiet, +4, 0, -4 dB) while simultaneously rehearsing sets of five digits for recall (secondary task). High listening effort requires greater cognitive resources and is associated with reduced performance on the secondary task. The study sample consisted of 31 normal-hearing children (9-12 years). Performance was generally maintained on the listening task when multitasking; however, performance decreased on the secondary recall task, especially at the more negative SNRs. This demonstrates that considerable listening effort is required when listening at SNRs that are typical of the school classroom.

Current bilateral BAHA configurations, for sounds directly facing listeners, will apply forces that are in-phase with each other and directed roughly towards the center of the head. Below approximately 1000 Hz the two cochleae respond in approximately the same direction and with approximately the same phase to each BAHA, thus it may be preferable to drive bilateral BAHAs such that when one pushes, the other pulls. This can be achieved by adjusting the relative phase offset of the BAHAs, and doing so results in greater vibration and improved hearing threshold. In this paper we compare performance of bilateral BAHAs driven in this configuration to the standard configuration. In twelve normal participants we show significant improvements in low-frequency (<= 750 Hz) hearing thresholds using out-of-phase BAHAs. The threshold measurements are further supported by velocimetric measurements taken at the cochlear promontory in a cadaveric head. Comparing vibration arising from each configuration confirms that out-of-phase driving results in greater vibration. Neither dataset shows either improved or reduced threshold at high frequencies.

Moore and Sek (2009) developed a fast and easy to administer test of sensitivity to TFS, but it can only be used at medium to high frequencies. Here we describe a binaural method that can be used at lower frequencies. An adaptive two-alternative forced-choice task was used. Each interval contained four tones with frequency f; in one interval all tones were diotic, and in the other tones one and three were diotic while tones two and four had an interaural phase shift, Delta phi. The task was to identify the interval with the phase-shifted tones. For normal-hearing subjects, the effects of sensation level and training on performance were small, and the test could be performed reliably for f - 250, 500, and 750 Hz.

People who present manifestations of hearing loss are often perceived by others to be cognitively diminished, less able, and socially incompetent. In order to avoid being identified as a member of a stigmatized group, individuals with hearing loss may choose not to seek health services or fail to comply with recommended treatments. The purpose of this study was to better understand how stigma impacted upon the help-seeking activities of adults with an acquired hearing loss. Ten people who had hearing loss, and were members of peer-support groups participated in audio-recorded semi-structured interviews. Verbatim transcripts were analysed using thematic analyses. Analyses revealed that lasting decisions about hearing loss management were made following 'critical junctures', when the negative stress found in the respondent's social and physical environment far outweighed positive energy, or when the positive energy found in the respondent's environment far outweighed the negative stress. The time course development of these processes is described. C1 [Southall, Kenneth; Gagne, Jean-Pierre] Univ Montreal, Ctr Rech, Inst Univ Geriatrie Montreal, Montreal, PQ H3W 1W5, Canada.

A total of 273 newborn babies (106 males and 147 females) were assessed twice (Test 1 and Test 2) on the same day, followed by two more assessments (Test 3 and Test 4) for 118 babies (48 males and 70 females) who returned six weeks later. Five HFT measures including the peak compensated static admittance and component compensated static admittance were assessed for test-retest reproducibility. The results showed no significant differences in mean values of the HFT results between the test and retest conditions for newborn (Test 1/ Test 2) and six-week-old babies (Test 3/ Test 4). High reproducibility for all HFT measures was found for both age groups, as judged by the high intra-correlation coefficients of between 0.75 and 0.95. Normal variations of the HFT measures were established using the 90% range of absolute test-retest difference. Changes in test-retest findings exceeding the 95th percentile values may be considered significant, indicating possible functional changes.

Nonsense syllables were degraded using two schemes (PM: phase modulation; FM: frequency modulation) designed to remove temporal envelope (E) cues while preserving TFS cues in 16 0.35-octave-wide frequency bands spanning the range of 80 to 8020 Hz. For both schemes, hearing-impaired listeners performed significantly above chance level (PM: 36%; FM: 31%; chance level: 6.25%), but more poorly than normal-hearing listeners (PM: 80%; FM: 65%). Three hearing-impaired listeners showed normal or near-normal reception of nasality information. These results indicate that for mild to moderate levels of hearing loss, cochlear damage reduces but does not abolish the ability to use the TFS cues of speech. The deficits observed for both schemes in hearing-impaired listeners suggest involvement of factors other than only poor reconstruction of temporal envelope from temporal fine structure.

Two groups of 12 subjects participated: younger individuals (22-29 years, M = 24.3) and older adults (50-69 years, M = 57.5). Mean hearing threshold levels (250 to 8000 Hz) for both groups were 30 dB HL or better. Most comfortable listening level (MCL) and background noise level (BNL) measurements were completed in each reverberant condition, and from these measurements, ANLs were calculated. Significant main effects for age and reverberation were not found for ANL or MCL. These results suggest that reverberation does not affect the amount of background noise individuals are willing to accept, or the level of speech individuals choose as the MCL. These results can be used by clinical audiologists to counsel patients regarding the use of communication strategies. Additionally, these results can be used to support previous findings that ANL is not related to the intelligibility of the speech signal.

Its deign comprised a cross-sectional investigation of members of a self-help group, using a questionnaire of positive experiences, an oto-neurological questionnaire, EuroQol, and Meniere's impact rating. The study sample was 542 members of the Finnish Meniere Federation. Results showed that the positive questions explained 21% of the variance of the EuroQol TTO, 31% of the EuroQol VAS measure, and 35% of the Meniere's impact. This compared with 40% of the variance explained by symptomatic complaints. When both the symptoms and positive measures were taken together, there was an increase in the proportion of the variance explained for the VAS (42%) and Meniere's rating (50%), but not for the TTO (42%). A perspective on the disorder was the main positive experience associated with the increased variance explained. Positive experiences have a significant impact on self-rated quality of life. The results suggest that encouraging a positive perspective on the condition, in addition to treating the underlying symptoms, could be useful in rehabilitative management.

ID EXPERIENCE; SYLLABLES; CHILDREN; SOUNDS; PITCH AB Based on studies in English speakers, it has been proposed that speech-evoked brainstem responses (ABRs) may be used clinically to assess central auditory function. Whether the same procedure can be used across speakers of different languages remains unclear, because recent findings suggest that language experience affects even subcortical processing of speech. The goal of the present study was to characterize brainstem responses to the syllable /da/ in Arabic and Hebrew speakers using the US developed BioMARK procedure. To that end, ABRs evoked by clicks and the syllable /da/ were collected from 37 normal-hearing students from the University of Haifa. Neither the transient nor the sustained components of the brainstem response differed significantly between Arabic and Hebrew speakers. Across the two groups, timing of the major components of the speech-evoked response as well as the correlations between the speech- and click indices were well within the US norms. Therefore, brainstem processing of the syllable /da/ does not differ between speakers of English and speakers of Semitic languages such as Arabic and Hebrew.

The size and shape of the DD 45 transducer resembles the classic Telephonics TDH 39 earphone. Pure-tone hearing threshold measurements were performed for both ears of 29 test subjects. All audiometric frequencies from 125 to 8000 Hz were used. The data are intended for inclusion in future standardized reference equivalent threshold sound pressure levels.

TI Modelling the speech reception threshold in non-stationary noise in hearing-impaired listeners as a function of level SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Hearing aids; Psychophysics; Prevention; Occupational hearing loss; Speech perception ID INTELLIGIBILITY; PARAMETERS; QUIET AB The extended speech intelligibility index (ESII) model (Rhebergen et al, 2006) forms an upgrade to the conventional speech intelligibility index model. For normal-hearing listeners the ESII model is able to predict the speech reception threshold (SRT) in both stationary and non-stationary noise maskers. In this paper, a first attempt is made to evaluate the ESII with SRT data obtained by de Laat and Plomp (1983), and Versfeld and Dreschler (2002) of hearing-impaired listeners in stationary, 10-Hz interrupted, and non-stationary speech-shaped noise measured at different noise levels. The results show that the ESII model is able to describe the SRT in different non-stationary noises for normal-hearing listeners at different noise levels reasonably well. However, the ESII model is less successful in the case of predicting the SRT in non-stationary noise for hearing-impaired subjects. As long as the present audibility models cannot describe the auditory processing in a listener with cochlear hearing loss accurately, it is difficult to distinguish between raised SRTs due to supra-threshold deficits or factors such as cognition, age, and language skills.

The listeners were fitted bilaterally with CIC and BTE hearing aids having similar bandwidth capabilities. The goal was to determine whether differences in microphone placement for these two styles (CICs at the ear canal entrance; BTEs above the pinna) would influence the availability of pinna-related spectral cues and hence localization performance. While lateral and polar angle localization was unaffected by the hearing aid style, the rate of front-back reversals was lower with CICs. This pattern persisted after listeners accommodated to each set of aids for a six week period, although the overall rate of reversals declined. Performance on all measures in all conditions was considerably poorer than in a control group of listeners with normal hearing.

Four groups of 40 older adult participants completed the SSQ twice at an interval of about a half year, using either the same or different administration methods at the two test times. The SSQ was administered using an interview method and/or it was self-administered and then returned by mail. Although the method of test administration did not systematically affect scores on the SSQ, the highest test-retest correlation (r = 0.83) was observed using the interview method at both test times, making it the best choice for the purpose of demonstrating the effectiveness of interventions. The other three combinations of dual-administration in this study also provided reliable results and may be preferable because the self-administration method is less time-consuming and labour-intensive. In conclusion, both the interview and self-administration methods are recommended, but with the best choice depending on the goals of the tester.

Linear filtering was used to implement the CAMEQ2-HF-prescribed gains for speech with an input level of 65 dB SPL. The results obtained using four normal-hearing (NH) and fifteen hearing-impaired (HI) listeners showed: (1) The gains were sufficient to make components above 5 kHz audible when those components were presented alone, and when they were presented together with the lower-frequency components; (2) NH listeners preferred a wider bandwidth (10 or 7.5 kHz versus 5 kHz) for both pleasantness and speech clarity, while HI listeners usually preferred a narrower bandwidth for pleasantness but a wider bandwidth for clarity; (3) HI listeners performed better on the 'S-test' (detection of word-final /s/ or /z/) with a wider than with a narrower bandwidth (7.5 versus 5 kHz); (4) Identification of vowel-consonant-vowel nonsense syllables improved with increasing bandwidth from 5 to 7.5 kHz for the NH but not for the HI listeners.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Adenomatous polyposis coli; Hearing loss, Sensorineural; Audiometry, Pure tone ID PROTEIN; LOCALIZES AB The mutation causing familial adenomatous polyposis (FAP) affects the adenomatous polyposis coli (Apc) gene, which has a role in the cytoskeleton and has been shown to be important in the structure of supporting cells in the cochlea. One previous study suggested that FAP sufferers may have sensorineural hearing loss. In order to demonstrate whether this is the case we invited patients known to suffer from familial adenomatous polyposis to take part in our study. Audiograms were performed and compared to normal values for that patient's age and gender calculated using ISO standard data. Thirteen patients were included in the study analysis. No conductive hearing losses were identified. A statistically significant greater hearing loss was identified at 500 Hz (2.8 dBHL, P = 0.03) and 1000 Hz (2.5 dBHL, P = 0.05). No audiometric difference could be identified between the patients with FAP and attenuated FAP. A power calculation demonstrated that the study was of adequate size. This study did not demonstrate a clinically significant difference in hearing loss between the FAP group and the calculated normal values. C1 [Jones, Stephen E.

Medical records from individuals diagnosed with childhood cancer and treated with platinum-based chemotherapy between 1985 and 2000 at the University Hospital in Lund Sweden were reviewed retrospectively. Fifteen subjects, who fulfilled the eligibility criteria set for the study, underwent a thorough audiometric evaluation. The results show that the hearing loss, in subjects with ototoxicity had increased after the end of treatment, to include also the lower frequencies. The largest deterioration in hearing thresholds, up to 55 dB HL, was found at frequencies above 2 kHz. The findings also reveal that the subjects have a considerably greater hearing loss handicap and disability than would be expected from the results of the audiometric evaluations. The conclusion of this study is that children and adolescence treated with platinum-based chemotherapy should have regular audiometric follow-up examinations, also many years after the end of treatment. Furthermore, assessments of self-reported hearing disability should be made during and after chemotherapy.

Eleven normal volunteers served as subjects. Six caloric stimulus delivery conditions included air with two speculum sizes, speculum only and with a rubber tube extension, and water. The resulting nystagmus was used as an index of stimulus efficiency. The effectiveness of the air stimulus was found to be dependent on the diameter of the speculum used for air delivery. The narrower speculum generated nystagmus that was typically twice that generated by the wider speculum. Users of air caloric equipment whose design includes a speculum that influences the effectiveness of the stimulus should be aware of this dependency and ensure their clinical interpretation of results is made with reference to appropriate normative data.

TI Effect of changing pulse rate on profile parameters of perceptual thresholds and loudness comfort levels and relation to ECAP thresholds in recipients of the Nucleus CI24RE device SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implant; electrically evoked compound action; potentials; stimulation rate; processor fitting ID COCHLEAR IMPLANT; PROCESSOR; CHILDREN; EAP AB The Nucleus CI24RE 'Freedom' device offers higher stimulation rates and lower noise levels in action potential measurements (ECAPs) than previous devices. A study including ten European implant teams showed that the effect of changes in rate from 250 to 3500 pulses per second on tilt and curvature of the T and C profiles is insignificant. When changing rate one may change the levels at all electrodes by the same amount. Using an automated procedure ECAPs could be measured quickly and reliably at a noise level of only 1 mu V. However, this did not result in improved correlations between the tilt and curvature parameters of the ECAP profiles and those of the T and C profiles. Average C levels appear to differ markedly among implant centers; a better assessment protocol is required. When increasing stimulus rate one should take into account that this requires higher pulse charges per second and more power consumption.

A 41-year-old male, totally deaf after a bilateral TB fracture, underwent an audiological, electrophysiological, and imaging investigation in order to assess the integrity of the VIIIth cranial nerves. Five months later he received a simultaneous bilateral CI. Speech perception tests were conducted at different time points. A significant advantage by dichotic listening was observed since the beginning of the habilitation program. The patient achieved a 100% word and sentences recognition in quiet at 12 months. His listening skills in noisy conditions were improved by the use of two implants. A CI in TB fractures is feasible if the VIII nerve is intact and the cochlea is spared by the fracture rim. The early timing of the procedure probably contributed to its success by preventing cochlear fibrosis and ossification.

The relative masking level (RLM) of twenty normally-hearing volunteers was measured behaviourally using ipsilaterally presented unfiltered noise in the presence of ABR stimuli. The upper limit for RLM was found to be typically 30 dB above the stimulus level when the stimulus was calibrated in dBnHL to ISO 389-6 (2007) and the noise was measured in dBSPL. This value is recommended when calculating the level of noise necessary to prevent cross-hearing during ABR testing.

Nevertheless, some individuals are unsuccessful with this strategy. The goals of the present study were to develop tests to improve the diagnostic test battery before rehabilitation of hearing-impaired persons with bilateral or unilateral amplification, and to evaluate the tests with normally-hearing subjects and with two groups of hearing-impaired persons. The latter two groups contained 11 successful and 11 unsuccessful users of bilateral amplification respectively. Hearing thresholds, speech recognition in noise, signal analysis ability, binaural abilities, and dichotic tests were used in the investigation. The subjects answered a questionnaire and hearing aid gain curves were measured. The results for the two groups were similar for peripheral hearing functions and binaural performance. The unilateral amplification group showed significantly worse results in speech-in-noise and dichotic tests. Spatial aspects within the questionnaire were correlated to amplification preference. We therefore suggest the inclusion of speech-in-noise, dichotic tests, and questions on spatial orientation into the diagnostic scheme before rehabilitation with hearing aids.

The study included 1633 adult subjects with normal hearing or symmetric sensorineural hearing impairment who underwent pure-tone audiometry between July 2007 and December 2008. K-means cluster analysis was employed to categorize audiometric shapes. Eleven audiogram shapes were identified: rising, flat, peaked 8-kHz dip, 4-kHz dip, 8-kHz dip, mild sloping, severe 8-kHz dip, sloping, abrupt loss, severe sloping, and profound abrupt loss. By using the classification system and nomenclature identified for audiogram shapes as outlined in this study, errors based on personal experiences can be reduced and a consistency can be developed across clinics.

The present study was designed to test a number of delay and high-pass combinations under worst-case (i.e. most sensitive) conditions. Eighteen normal-hearing and 18 mildly hearing-impaired subjects performed the test in a paired comparison (A/B) task. The subjects were asked to select a preferred setting with respect to sound quality. The test was set in an anechoic chamber using recorded speech, environmental sounds, and own voice. Experimental hearing aids were fitted binaurally with open domes thus providing maximum ventilation. The preference data were processed using a statistical choice model that derives a ratio-scale. The analysis indicated that in these test conditions there was no change in sound quality when varying the delay in the range 5-10 ms and that there was a preference for 2000 Hz high-pass filtering in most conditions, regardless of the hearing losses tested.

TI Studying tinnitus in the ICF framework SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Behavioral measures; Psycho-social/emotional; Psychoacoustics/hearing science; Tinnitus ID QUALITY-OF-LIFE; OLDER-ADULTS; PREVALENCE; ATTENTION; ANNOYANCE AB Activity limitation and participation restriction (AL/PR) on account of tinnitus was studied in the ICF framework in order to understand how tinnitus restricts individuals from fulfilling social and economic obligations. The objective of the study was to study the impact of tinnitus in the framework of ICF. Twenty-one adults in the age range of 20-60 years with chronic tinnitus (> 3 months) and with normal hearing sensitivity were included in the study. THI was mapped to the framework of ICF. Twenty out of twenty-five items belonged to the domains under body function and five items addressed AL/PR. Five more AL/PR items applicable to tinnitus were added to THI. The THI + ICF questionnaire tested well on test reliability (0.987) and internal consistency (0.873). Body function was significantly more affected than AL/PR (P = 0.0005). These results suggest that tinnitus does not result in significant AL/PR from the ICF perspective. Further, psycho-acoustic characteristics such as intensity, frequency of tinnitus, and time since onset of tinnitus have only minimal if any impact on AL/PR.

All participants were right-handed and included a group of young adults with normal hearing and a group of older adults with minimal sensorineural hearing loss. In all conditions, performance by the young adults was better than performance by the older adults. A right-ear advantage was observed for both groups. Due to a greater deficit in dichotic digits recognition performance in the left ear of older subjects their right-ear advantages were larger than those for the young adults. The results support an age-related disadvantage in recognition performance for dichotic stimuli presented to the left ear of older subjects that is not entirely accounted for by differences in hearing sensitivity between subject groups but may be related to a primary cognitive deficit.

TI Speech perception performance as a function of stimulus pulse rate and processing strategy preference for the Cochlear (TM) Nucleus (R) CI24RE device: Relation to perceptual threshold and loudness comfort profiles SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implant; Speech perception; Stimulation rate; Processor fitting ID AUDITORY-NERVE FIBERS; STIMULATION RATE; ELECTRICAL-STIMULATION; RECOGNITION; SYSTEM; IMPLANTS; TALKER AB Current cochlear implants can operate at high pulse rates. The effect of increasing pulse rate on speech performance is not yet clear. Habituation to low rates may affect the outcome. This paper presents the results of three subsequent studies using different experimental paradigms, applying the Nucleus CI24RE device, and conducted by ten European implant teams. Pulse rate per channel varied from 500 to 3500 pulses per second with ACE and from 1200 to 3500 pps with CIS strategy. The results showed that the first rate presented had little effect on the finally preferred rate. Lower rates were preferred. The effect of pulse rate on word scores of post-linguistic implantees was small; high rates tended to give lower scores. However, there were no significant differences between the word scores across subjects if collected at the individually preferred pulse rate. High pulse rates were preferred when the post-implantation threshold was low. C1 [Smoorenburg, Guido F.] La Palladienne, F-83890 Plan Peyrassou, Besse Issole, France.

TI Uncomfortable loudness levels in experienced unilateral and bilateral hearing aid users: Evidence of adaptive plasticity following asymmetrical sensory input? SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Uncomfortable loudness level; Hearing aid; Acclimatisation; Reorganisation; Functional plasticity; Central gain process ID FUNCTIONAL PLASTICITY; TIME-COURSE; BRAIN-STEM; ACCLIMATIZATION; DEPRIVATION; LISTENERS AB Munro and Trotter [Inter J Audiol 45, 684-688, 2006] reported an asymmetry in uncomfortable loudness levels (ULLs) in a preliminary study using 12 experienced unilateral hearing aids users. The aim of the present study was to investigate ULLs in a larger sample of listeners with unilateral and bilateral hearing aid experience. Participants were adults with symmetrical high-frequency hearing impairment. There were 48 listeners with unilateral experience, 13 listeners with bilateral experience and a control group of 47 listeners with no hearing aid experience. The minimum duration of hearing aid experience was 2 years. ULLs were measured at 0.5, 1, 2 and 4 kHz. The unilateral group showed a statistically significant inter-aural asymmetry of 3-5 dB. Compared to the controls, there was a non-significant trend of higher ULLs in the fitted ear and lower ULLs in the not-fitted ear. ULLs in the bilateral group were symmetrical and similar to the control group. The findings suggest that changes in ULL may be a feature of asymmetrical sensory input and are consistent with a central gain mechanism.

Data was drawn from two hospital-based and community-based NHS programs in Lagos, Nigeria, with a total screened population of 11 893 infants. Two automated TEOAE screening devices-Echo-Screen and ECHOCHECK-were available for this study. Ambient noise levels ranged from 61.0-90.5 dBA in the hospital wards and 55.6-82.5 dBA in the community health centers. One TEOAE model could not be activated at the prevailing noise levels. No significant pattern was observed in average noise levels and overall TEOAE referrals across all screening sites. However, the false-positive rates ranged from 1.4-13.8%. This study suggests that valid TEOAE screening is attainable in the Negroid race in settings with ambient noise levels up to 68 dBA but the associated high false-positive rates may necessitate additional screening with auditory brainstem response to achieve acceptable overall referral rates for timely diagnostic evaluation.

A narrative approach was used to gain an in-depth understanding of the meaning and contextual issues that impact upon the adaptation process of older adults and their transitions in using hearing devices. Four women over the age of sixty who were identified as being consistent hearing aid users took part in three face-to-face interviews. Wengraf's (2001) biographic-narrative-interview guiding framework was used to gather data in this study. Data were analyzed both holistically and thematically from a phenomenological perspective to identify the meaning and essence of the participants' experiences. The results revealed an overarching theme of meaningful participation in life situations and events that were linked to purposeful use and non-use of hearing aids. Barriers and facilitators related to participation, which in turn affect hearing aid use and acceptance, were uncovered. The results of this study have implications for audiologic research, and practice. C1 [Jennings, Mary Beth] Univ Western Ontario, Elborn Coll, Natl Ctr Audiol, London, ON N6G 1H1, Canada.

Participants: Thirty adults with varying degrees and configurations of hearing loss ranging from mild to severe. Methods: Hearing aid output was measured after the initial fitting to DSL v5.0a targets and after determination of the PLL after approximately 90 days. The Client Oriented Scale of Improvement (COSI) was used to evaluate outcome. Results: The 95% confidence interval of fits to target ranged from 5.8 to 8.4 dB across frequency. The DSL v5.0a adult algorithm approximated the PLLs of the participants within 2.6 dB on average. Hearing aid fittings provided positive subjective outcome improvements on the COSI. Conclusions: Findings suggest that the use of DSL v5.0a for the fitting of hearing aids on adults with acquired hearing loss was feasible and provided an appropriate initial fitting.

TI The effects of a second stimulus on the auditory steady state response (ASSR) from the inferior colliculus of the chinchilla SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Auditory steady state response; Inferior colliculus; Chinchilla ID ENVELOPE FOLLOWING RESPONSE; MODULATION-FOLLOWING RESPONSE; BRAIN-STEM RESPONSE; BINAURAL INTERACTION COMPONENT; FREQUENCY-FOLLOWING RESPONSE; GATED PURE-TONES; MONGOLIAN GERBIL; STOCHASTIC RESONANCE; CENTRAL MASKING; THRESHOLD AB The auditory steady-state response (ASSR) is an auditory evoked potential which follows the envelope of the stimulus. One of the advantages of the ASSR is that multiple stimulation frequencies can be tested simultaneously. In experiment 1, we evaluated the effects of simultaneously presenting two separate stimuli on ASSR response amplitude. In experiment 2, we evaluated the effects of presenting two ASSR-generating stimuli monotically vs. dichotically, either ipsilaterally or contralaterally to the recording electrode. Recordings were made from the chinchilla inferior colliculi, in response to tonebursts, two-tones, or sinusoidally-amplitude modulated tones. We found that the addition of a second stimulus resulted in a reduction in ASSR response amplitude at moderate to high stimulus levels. The amount of amplitude reduction was typically larger in the monotic (e.g. similar to 50%) vs. dichotic condition (e.g. similar to 10-20%), regardless of whether the responses were recorded ipsilaterally or contralaterally to the ear of stimulus presentation. In conclusion, central as well as peripheral interactions contribute to the reduction in ASSR amplitude in response to the simultaneous presentation of multiple stimuli C1 [McNerney, Kathleen M.; Burkard, Robert F.] SUNY Buffalo, Dept Rehabil Sci, Buffalo, NY 14214 USA.

TI Hearing aids as an adjunct to counseling: Tinnitus patients who choose amplification do better than those that don't SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Tinnitus; Hearing aids; Counseling; Treatment outcome; Habituation; Amplification; Sound therapy ID HANDICAP-QUESTIONNAIRE; PSYCHOMETRIC PROPERTIES; BENEFITS AB Hearing aids are commonly used for tinnitus management (Kochkin & Tyler, 2008) but there is limited evidence to support their use. The purpose of this study was to quantify the effectiveness of hearing aids and counseling as a tinnitus treatment option. This study is a retrospective analysis of tinnitus handicap questionnaire (THQ, Kuk et al, 1990) results from 58 tinnitus patients with hearing loss who received counseling, and (1) chose to follow recommendations of hearing aid fitting, or (2) chose not to have hearing aids. The groups (N = 29 each) had similar audiometric configuration, tinnitus duration, and age. It was hypothesized that the use of hearing aids would provide greater reduction in THQ scores than counseling alone. THQ scores were reduced 12 months following counseling but improvement in THQ only reached statistical significance for the group that received hearing aids (p < 0.0001). The hearing aid group had reduced; psychosocial handicap (p < 0.0002); and tinnitus-hearing handicap (p < 0.0005). It is concluded that patients with hearing loss and tinnitus should trial amplification. C1 [Searchfield, Grant D.; Kaur, Manpreet] Univ Auckland, Audiol Sect, Auckland 92019, New Zealand.

Participants (n = 2922, aged 48-92 years) not reporting tinnitus at baseline (1993-1995) were followed for up to ten years. In addition to audiometric testing and anthropometric measures, data on tinnitus, health, and other history were obtained via questionnaire. Potential risk factors were assessed with discrete-time proportional hazards models. The 10-year cumulative incidence of tinnitus was 12.7%. The risk of developing tinnitus was significantly associated with: history of arthritis (hazard ratio (HR) = 1.37), history of head injury (HR = 1.76), history of ever smoking (HR = 1.40), and among women, hearing loss (HR = 2.59). Alcohol consumption (HR = 0.63 for >= 141 grams/week vs. < 15 grams/week), age (among women, HR = 0.90 for each five-year increase in age), and among men, obesity (HR = 0.55), were associated with decreased risk. The risk of developing tinnitus was high for older adults, and associated with modifiable health and behavioral factors. C1 [Nondahl, David M.; Cruickshanks, Karen J.; Klein, Barbara E.

The aims of this study were to describe outcomes for a large sample of clients fitted with hearing aids and to investigate factors associated with mean IOI-HA scores, with a view to providing guidance about factors that warrant particular attention in the clinic in order to improve outcomes. Measures used were the international outcome inventory hearing aids (IOI-HA; Cox & Alexander, 2002) and a series of questions about satisfaction with hearing aid performance in different listening situations, hearing aid attributes, and clinical service. The participant sample consisted of 1653 adults, most often fitted bilaterally (78%); 81% had digital aids with at least two listening programs. Results of the regression analysis indicated that there were a number of significant factors that, in total, explained 57% of the variance in IOI-HA scores. Higher mean IOI-HA scores were most strongly associated with greater satisfaction with hearing aid attributes of aid fit/comfort, clarity of tone and sound, and comfort with loud sounds and with satisfaction in the listening situations of conversation with one person, in small groups, in large groups, and outdoors. These findings highlight the importance of focusing rehabilitation on improving satisfaction with aided listening across a range of environments and with key attributes of hearing aid performance.

Advances in genetics have made it possible to identify several genes related to HI. This information can cast light upon prognostic factors regarding the outcome in cochlear implantation, and provide information both for scientific and genetic counselling purposes. From 1992 to 2005, 273 children from 254 families (probands) were offered cochlear implants in Norway. An evaluation of the causes of HI, especially regarding the genes GJB2, GJB6, SLC26A4, KCNQ1, KCNE1, and the mutation A1555G in mitochondrial DNA was performed in 85% of the families. The number of probands with unknown cause of HI was thus reduced from 120 to 68 (43% reduction). Ninety-eight (46%) of the probands had an identified genetic etiology of their HI. A relatively high prevalence of Jervell and Lange-Nielsen syndrome was found. The main causes of severe and profound HI were similar to those found in other European countries. GJB2 mutations are a common cause of prelingual HI in Norwegian cochlear implanted children. C1 [Siem, Geir] Univ Oslo, Oslo Univ Hosp, Rikshosp, Dept Otolaryngol, N-0027 Oslo, Norway.

According to the literature, nystagmus and vertigo may be more pronounced when the affected ear is either up or down. In some patients, both right and left D-H tests can trigger nystagmus with the same direction. The proposed treatment options with the addition of a different manoeuvre applied by the authors of the present study in cases of ASC lithiasis, seem to present a respective variety regarding the position of the affected ASC during the procedure of canalith repositioning. The aim of this study is to analyse the mechanisms underlying both the proposed treatment options and the clinical findings in the D-H examination. The results of this analysis stimulate further investigation, since they probably imply that repositioning manoeuvres might vary in their effectiveness when applied to different clinical subgroups of ASC BPPV.

This experience is referred to as King-Kopetzky syndrome (KKS), obscure auditory dysfunction (OAD), or auditory processing disorder (APD). Logistic regression was used to consider the associations between help-seeking and a range of audiological and illness perception measures. Results indicate that help-seekers present with poorer speech in noise thresholds than non help-seekers, and that coherent illness perceptions and a negative belief in the consequences of hearing difficulties are associated with help-seeking status, regardless of hearing sensitivity.

These cases are clinically categorized as King-Kopetzky syndrome (KKS), obscure auditory dysfunction (OAD), or auditory processing disorder (APD). While recent research has focussed on the possible mechanistic basis for these difficulties, the perceptions of the hearing difficulties that lead people to seek help have not hitherto been identified. This study presents findings from an observational survey of causal attributions of hearing difficulties from 100 people with KKS. The findings suggest that participants regard immunity and risk related causes of hearing difficulties as pre-dominant. Psychological factors were not considered to be causal for hearing difficulties. These factors were not affected by diagnostic classification. These findings inform audiologists about their patient beliefs for the first time. The authors suggest that clinicians take care to ensure that their counselling is responsive to these beliefs.

Discrimination abilities of non-native speech sounds (Malayalam) from its native counterparts (Hindi) were monitored during 12 days of training. Contralateral inhibition of otoacoustic emissions were measured on the first and twelfth day of training. Results suggested that training significantly improved reaction time and accuracy of identification of nonnative speech sounds. There was a significant positive correlation between the slope (linear) of identification scores and change in distortion product otoacoustic emission inhibition at 3000 Hz. Findings suggest that during perceptual learning feed back from the MOCB may fine tune the brain stem and/or cochlea. However, such a change, isolated to a narrow frequency region, represents a limited effect and needs further exploration to confirm and/or extend any generalization of findings.

However, the reasons why people choose particular interventions and not others have not been systematically investigated. This study explored the factors influencing the rehabilitation decisions of adults with acquired hearing impairment. Four options (hearing aids, group communication program, individual communication program, and no intervention) were discussed using shared decision making with 153 adults with acquired hearing impairment who had not previously received hearing rehabilitation. A selected sub-sample of 22 participants described the factors that influenced their decision during a semi-structured interview. Using qualitative content analysis, seven categories of factors influencing rehabilitation decisions were identified: (1) convenience; (2) expected adherence and outcomes; (3) financial costs; (4) hearing disability; (5) nature of intervention; (6) other people's experiences, recommendations, and support; and (7) preventive and interim solution. All categories of factors were a positive influence for a particular intervention for some participants and a negative influence for the same intervention for other participants. The results support a client-centred approach to decision making.

A questionnaire was developed and completed by 25 students (bilateral hearing aid users, 10-20 years old). Responses for hearing aid microphone mode (M) and telecoil mode (T) were collected. Two attributes, audibility and awareness, were identified and assigned to either mode. Better audibility was achieved in T-mode. Students with severe hearing loss benefited more using T-mode when compared to the better hearing students, especially in more difficult listening situations. Better awareness was achieved in M-mode; students could better hear, locate and segregate sounds in the environment around them. Depending on the situation, students make different choices between audibility and awareness. Self-assessment is a promising approach for determining what combination of ALD design and function that will best benefit the students.

Subjects consisted of 91 inpatients with tinnitus and hyperacusis. The GUF showed a good reliability (alpha=.92). The factorial structure of the questionnaire reported by Nelting et al (2002) was not completely supported by the evidence in this study. The total score and the single items showed small to moderate correlations with the other modes of measuring hyperacusis. Evidence for convergent and discriminant validity were found, but overall the results corroborate the conceptual heterogeneity of the construct hyperacusis and its dependency on the assessment method. Four items of the GUF with particularly low correlations were excluded from the questionnaire. The revised GUF total score showed slightly but not statistically significant higher convergent and discriminant validity.

Young children are sometimes initially provided with such maps and the aim was to gain an insight into what level of benefit they might provide. Maps with upper stimulation levels set equally across the array (i.e. 'flat' maps) were compared with normal 'customized' maps in established adult users of the MED-EL C40+ device. Speech discrimination was significantly poorer for the flat maps overall (mean of 72.7% for customized map, and 60.5% for flat map) and loudness balance estimates showed a range of degrees of imbalance. These results suggest that flat maps may provide paediatric CI users with useful levels of performance when psychophysical or objective measures cannot be obtained. The poorer performance with the flat map suggests that customized maps should be fit as soon as possible to provide paediatric patients with the maximum benefit of the CI device.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Insertion gain; Digital feedback suppression; Hearing instruments; Modified pressure method; Real-ear measurements; Verification AB Audiologists typically verify hearing instrument fitting using real-ear measurements (REM) Recently the modified pressure with stored equalization method (MPSE) has been recommended for use when verifying open non-occluding hearing instruments The MPSE method does not use a reference microphone to maintain loudspeaker output during real-ear measurements and is therefore susceptible to changes in the signal level at the client's ear which result from movement of the client's head and torso during the verification process To determine the size of these errors, the real-ear unaided response (REUR) was measured prior to and following the Oiling of a non-functioning hearing aid in the contralateral ear Twenty young adults participated Identical head positions for the two measurements should yield zero difference measures across all frequencies measured Loudspeaker-to-client azimuths of 0 degrees and 45 degrees were investigated Mean difference measures across the frequencies investigated were less than 1dB for both azimuths with one standard deviation from these mean differences typically less than 15 dB Results suggest that the MPSE method does not introduce clinically significant errors in real-ear measurements when verifying hearing instrument fitting in the population examined.

In particular the associations of hearing loss, level of signal processing, and fitting type ( bilateral versus unilateral fitting) with hearing aid use, satisfaction with and management of the aid were evaluated. A sub-group with symmetrical hearing loss was analysed (n = 6027). Regular use was more frequent in bilateral users and in owners of devices with more complex signal processing, but the strongest determinant of regular use was severity of hearing loss. Satisfaction was higher in the group wearing simple devices, while fitting type and degree of hearing loss had no influence on satisfaction rates. Moderate and severe hearing loss was associated more frequently with poor management of the aid than mild hearing loss. It was concluded that bilateral amplification and advanced signal processing features may contribute to successful hearing aid fitting, but the resulting differences must be considered to be relatively small.

Quentin TI Effectiveness of computer-based auditory training for adult users of cochlear implants SO INTERNATIONAL JOURNAL OF AUDIOLOGY LA English DT Article DE Cochlear implants; Auditory training; Auditory learning ID IMPAIRED CHILDREN; DISTORTED SPEECH; PERFORMANCE; ADAPTATION; DISCRIMINATION; PERCEPTION; LISTENERS; TIME AB Cochlear implantation is effective at restoring partial hearing to profoundly deaf adults, but not all patients receive equal benefit. The present study evaluated the effectiveness of a computer-based self-administered training package that was designed to improve speech perception among adults who had used cochlear implants for more than three years. Eleven adults were asked to complete an hour of auditory training each day, five days a week, for a period of three weeks. Two training tasks were included, one based around discriminating isolated words, and the other around discriminating words in sentences. Compliance with the protocol was good, with eight out of eleven participants completing approximately 15 hours of training, as instructed. A significant improvement of eight percentage points was found on a test of consonant discrimination, but there were no significant improvements on sentence tests or on a test of vowel discrimination. Self-reported benefits were variable and generally small. Further research is needed to establish whether auditory training is particularly effective for identifiable sub-groups of cochlear-implant users.
