AB Sensorineurally hearing-impaired ( HI) subjects often report difficulties in complex acoustical environments. To investigate whether these problems arise from specific deficits in the frequency selectivity in binaural listening conditions, thresholds were measured for a 500-Hz sinusoid in phase ( So) or antiphase (S pi) masked by a diotic notched noise ( No). The equivalent rectangular bandwidth (ERB) for filters derived from diotic (NoSo) and dichotic (NoS pi) threshold curves is larger for the HI subjects than for the normal-hearing (NH) subjects. However, the ratio of binaural to monaural ERB is the same. The data indicate that there is no additional retrocochlear impairment reducing the binaural frequency selectivity of HI subjects. A specific binaural impairment was also tested by measuring the perception of binaural pitch (Huggins' pitch). Two out of eight HI subjects failed to perceive this pitch, although in the masking experiment they obtained a binaural masking-level difference of up to 10 dB. The current data therefore provide no clear evidence for a specific binaural impairment factor in hearing impairment that deteriorates several aspects of binaural processing in a similar way.

AB This study aimed to determine if adolescents/young adults gained additional perceptual benefit from sequential bilateral cochlear implants within 12 months, and to document adaptation to the second implant. Assessments comprised a pediatric version of The Speech, Spatial and Qualities of Hearing Scale (SSQ), anecdotal reports of device use and daily listening, and the Adaptive Spondee Discrimination Test (AdSpon). All nine participants achieved full-time use of, a preference for, and superior daily listening with, bilateral implants. Eight participants were comfortable using the second implant alone, and two achieved similar daily listening with either implant alone. SSQ ratings were higher post-operatively for the majority of participants. AdSpon performance was superior bilaterally for five participants with noise ipsilateral to the first implant, but not contralateral. Unilateral performance with either implant was similar for one participant. A second implant may provide additional benefit up to 19 years of age, even with congenital hearing loss and >16 years between implants. Families and clinicians should understand the aspects of second-implant candidacy and post-operative use that are unique to adolescents/young adults.

AB A French speech intelligibility screening test in noise that applies digit triplets as stimuli has been developed and evaluated for both telephone and broadband headphone use. After optimizing the speech material based on the intelligibility of the individual digits, norms for normal-hearing subjects were established. Speech reception thresholds (SRTs) of -6.4 +/- 0.4 and -10.5 +/- 0.3 dB SNR, and slopes of 17.1 and 27.1 %/dB were obtained for telephone and broadband headphone presentation, respectively. The French digit triplet test by telephone was then implemented as an automatic self-screening test by home telephone, and further evaluated in normal-hearing and hearing-impaired listeners. A test-retest variability of 0.7 dB was found and the correlation between SRT and pure-tone average (PTA(0.5,1,2,4)) was 0.77. One month after launching the test, 20 000 calls were registered. It can be concluded that both versions of the newly developed test have steep slopes and small SRT differences across normal-hearing listeners. The screening test by telephone is highly reliable and proves to fulfill the need for an easily accessible and objective hearing screening.

AB A cross-sectional survey was conducted among 3646 persons, 15 to 23 years of age, in the southern plains District of Sarlahi, Nepal, to assess the prevalence and severity of hearing loss and middle-ear dysfunction, and adverse effects of hearing loss on social integration. Between 2006 and 2008, subjects were enumerated and underwent otoscopic, tympanometric, and audiometric evaluations at central sites in villages. Hearing loss was diagnosed in subjects who failed a hearing screening and exhibited an average air conduction threshold value greater than or equal to 30 dBHL in the worse ear. Clinically, 32.8% of subjects exhibited a dull or retracted tympanic membrane, and 18% had abnormal tympanometry. Nearly 12% failed the hearing screening test, among whom more than half, or 6.1% overall, had hearing loss. Hearing-impaired subjects were six- to eight-fold (ORs, with 95% CIs excluding 1.0) more likely to report problems in hearing usual sounds or communicating with other people. Among young adults living in southern Nepal, hearing loss is common, and associated with social disability.

AB The World Health Organization's International Classification of Functioning, Disability and Health (ICF) has adopted a multifactorial understanding of functioning and disability, merging a biomedical paradigm with a social paradigm into a wider understanding of human functioning. Altogether there are more than 1400 ICF-categories describing different aspects of human functioning and there is a need to developing short lists of ICF categories to facilitate use of the classification scheme in clinical practice. To our knowledge, there is currently no such standard measuring instrument to facilitate a common validated way of assessing the effects of hearing loss on the lives of adults. The aim of the project is the development of an internationally accepted, evidence-based, reliable, comprehensive and valid ICF Core Sets for Hearing Loss. The processes involved in this project are described in detail and the authors invite stakeholders, clinical experts and persons with hearing loss to actively participate in the development process.

AB The purpose of this research was to investigate the congruent/incongruent perceptions of hearing-loss related quality of life between members of couples and to determine how incongruence was affected by individual psychosocial characteristics, specifically measures of mood (negative affect and positive affect), stress, and communication in the marriage. An exploratory correlational analysis was performed on data for 52 couples in which only one member had a hearing loss. In the regression analyses the independent variables were hearing-loss related quality of life scores measured in people with hearing loss, measured in significant others, and differences in hearing-loss related quality of life among members of a couple. The results demonstrate that both in people with hearing loss and their significant others, perceptions of hearing-loss related quality of life is highly correlated with negative mood scores. Incongruence in hearing-loss related quality of life scores reported by members of a couple were highly correlated with negative affect measured within each individual. Future research evaluating the effectiveness of audiologic rehabilitation can use measures of mood as an outcome variable.

AB The objective of the present study was to evaluate the integrity of the peripheral and central auditory systems of sickle cell disease (SCD) patients, through electrophysiological evaluation utilizing auditory evoked potentials, and comparing the results obtained in SCD patients with individuals without SCD. A total of 80 individuals were evaluated: 40 SCD patients; and 40 healthy age- and sex-matched controls. Brainstem auditory evoked response (BAER) was used to check neural integrity and electrophysiological thresholds, and cognitive potential (P300) to analyse the auditory selective attention. Despite the exclusion of individuals with comorbidities typical of SCD, the predominance of hearing loss among the patients was detected in 16 ears (20%). The absolute latencies of the BAER were within the expected range but the SCD group showed a small but statistically significant reduction of the interpeaks I-V, indicative of cochlear alteration. P300 latency and amplitude were adequate for both groups suggesting the absence of central auditory system abnormalities. The present findings suggest that SCD causes variable degree of cochlear abnormalities without evidence of neural problems.

AB To describe the adaptive pattern of cortically generated auditory evoked potentials elicited by repeated stimuli via cochlear implants (CIs), the late auditory evoked potential (LAEP) was collected from nine postlingually deafened adult CI users. Tone bursts were presented in 30 trains consisting of 10 tone bursts each, with inter-stimulus intervals (ISIs) of 0.7 ms and inter-train intervals (ITIs) of 15s. The response to the first stimulus and the response to later tone bursts in the train were compared. Results showed that the LAEP for the first tone burst was larger than that for later tone bursts, displaying an adaptive pattern. This pattern appeared to be more prominent in CI users with good speech perception performance than in those with poorer performance. This finding is meaningful in the context of our future research to restore normal adaptation in CI users to improve their speech perception performance.

AB Objective: The objective of the present study was to compare three methods of estimating the audibility of aided speech using the Baha.
   Subjects: 23 Adult Baha users with primarily bilateral conductive hearing loss were recruited from the Bone Conduction Amplification Program at the Institute for Reconstructive Sciences in Medicine in Edmonton, Alberta, Canada.
   Methods: A test Baha was set to each subject's preferred listening level. The same Baha was used to assess the audibility of the long-term average speech spectrum (LTASS) for each of the following three approaches: 1) Aided soundfield thresholds, 2) Real Ear SPL, and 3) Real Head Acceleration Level. Results: Significant differences were discovered between the three approaches. Aided soundfield thresholds consistently over-estimated the sensation level of aided speech. The Real Ear SPL approach provided reasonable estimates in the mid-frequencies. However, low- and high-frequency estimates for the Real Ear approach have significant limitations.
   Conclusions: The Real Head Acceleration Level appears to be the most accurate method of determining aided audibility with the Baha.

AB Speech and music are time-varying signals organized by parallel hierarchical rules. Through a series of four experiments, this study compared the masking effects of single-talker speech and instrumental music on speech perception while manipulating the complexity of hierarchical and temporal structures of the maskers. Listeners' word recognition was found to be similar between hierarchically intact and disrupted speech or classical music maskers (Experiment 1). When sentences served as the signal, significantly greater masking effects were observed with disrupted than intact speech or classical music maskers (Experiment 2), although not with jazz or serial music maskers, which differed from the classical music masker in their hierarchical structures (Experiment 3). Removing the classical music masker's temporal dynamics or partially restoring it affected listeners' sentence recognition; yet, differences in performance between intact and disrupted maskers remained robust (Experiment 4). Hence, the effect of structural expectancy was largely present across maskers when comparing them before and after their hierarchical structure was purposefully disrupted. This effect seemed to lend support to the auditory stream segregation theory.

AB This study describes the prevalence and characteristics of noise-induced hearing loss (NIHL) in student musicians (N = 329) aged 18-25 years. Students completed a questionnaire regarding exposures before a hearing assessment. NIHL was defined by the presence of a notch 15 dB in depth at 4000 or 6000 Hz relative to the best preceding threshold. Overall prevalence of NIHL was 45%, with 78% of notches occurring at 6000 Hz. The proportion of the total population with bilateral notching at any frequency was 11.5%, mostly occurring at 6000 Hz. There was a significant increase in the frequency of notching in students who reported more than two hours per day of personal practice. There were no significant associations for instrument group or other noise exposures. The data suggest that susceptibility to NIHL among students of music is not uniform and cannot be ascribed solely to the instrument played and other exposures. Students with bilateral losses tend to have deeper notches and may represent a group that has an inherent predisposition to NIHL.

AB The aim of the study was to estimate the prevalence of the exposure to ototraumatic factors and auditory symptoms, and to analyse the relations between these factors in a group of young healthy men. A total of 839 men, 19-22 years old, were recruited for the study when reporting for primary military service. A questionnaire was distributed and audiometry was performed. The prevalence of tinnitus, sensitivity to noise, and measured hearing impairment in the study group was 23.2%, 15.5%, and 14.5% respectively. Exposure to occupational noise often was reported by 21.4%, and playing loud music often by 16.5%. The young men who had experienced tinnitus after noise exposure had an elevated risk of high frequency hearing impairment, tinnitus, and sensitivity to noise. Those who played loud music had elevated prevalence values of tinnitus but not of hearing impairment. In this young group we observed high prevalence values of ototraumatic factors and auditory symptoms. We also observed significant correlations between tinnitus after noise exposure, self-assessed hearing symptoms, and hearing impairment.

AB The aim of this study was to screen 349 patients affected by sensorineural hearing loss (SNHL), mostly from the Campania region (southern Italy), for GJB2 gene mutations and for two deletions of the GJB6 gene (del GJB6-D13S1830 and del GJB6-D13S1854). We identified pathogenetic GJB2 mutations in 51 cases (15% of patients). No GJB6 mutation was found. We also examined the audiologic features of the patients for whom we had an etiologic diagnosis, in order to identify correlations between the severity of hearing loss and the type of mutation.

AB Three studies are reported assessing the validity of AMTAS (R), an automated method for obtaining an audiogram, including air- and bone-conduction thresholds (stimuli delivered by a forehead-placed transducer) with masking noise presented to the non-test ear. In Study 1, six subjects at each of three sites were tested using manual audiometry by two audiologists at each site. The mean differences between the audiograms for the paired audiologists provided a measure of the reliability of traditional audiometry. In Study 2, thirty subjects (5 normal hearing, 25 hearing impaired) were tested using AMTAS and manual audiometry. For air- conduction thresholds, AMTAS-manual differences were similar to inter-tester differences in Study 1, but for bone-conduction thresholds, the former were larger. Two possible sources of the greater differences were identified, (1) incorrect reference-equivalent threshold force levels for forehead bone conduction, and (2) a differential effect of middle-ear disease on forehead and mastoid bone-conduction thresholds. In Study 3, intersubject variability was studied for forehead and mastoid bone-conduction thresholds. The results indicate similar variability for the two placement sites.

AB Permanent hearing loss is a leading global health care burden, with 1 in 10 people affected to a mild or greater degree. A shortage of trained healthcare professionals and associated infrastructure and resource limitations mean that hearing health services are unavailable to the majority of the world population. Utilizing information and communication technology in hearing health care, or tele-audiology, combined with automation offer unique opportunities for improved clinical care, widespread access to services, and more cost-effective and sustainable hearing health care. Tele-audiology demonstrates significant potential in areas such as education and training of hearing health care professionals, paraprofessionals, parents, and adults with hearing disorders; screening for auditory disorders; diagnosis of hearing loss; and intervention services. Global connectivity is rapidly growing with increasingly widespread distribution into underserved communities where audiological services may be facilitated through telehealth models. Although many questions related to aspects such as quality control, licensure, jurisdictional responsibility, certification and reimbursement still need to be addressed; no alternative strategy can currently offer the same potential reach for impacting the global burden of hearing loss in the near and foreseeable future.

AB Percutaneous bone anchored hearing aids (BAHA) are today an important rehabilitation alternative for patients suffering from conductive or mixed hearing loss. Despite their success they are associated with drawbacks such as skin infections, accidental or spontaneous loss of the bone implant, and patient refusal for treatment due to stigma. A novel bone conduction implant (BCI) system has been proposed as an alternative to the BAHA system because it leaves the skin intact. Such a BCI system has now been developed and the encapsulated transducer uses a non-screw attachment to a hollow recess of the lateral portion of the temporal bone. The aim of this study is to describe the basic engineering principals and some preclinical results obtained with the new BCI system. Laser Doppler vibrometer measurements on three cadaver heads show that the new BCI system produces 0-10 dB higher maximum output acceleration level at the ipsilateral promontory relative to conventional ear-level BAHA at speech frequencies. At the contralateral promontory the maximum output acceleration level was considerably lower for the BCI than for the BAHA.

AB Moore et al (1999b) described a procedure, CAMEQ, for the initial fitting of multi-channel compression hearing aids. The procedure was derived using a model of loudness perception for impaired hearing. We describe here the development of a new fitting method, CAMEQ2-HF, which differs from CAMEQ in the following ways: (1) CAMEQ2-HF gives recommended gains for centre frequencies up to 10 kHz, whereas the upper limit for CAMEQ is 6 kHz; (2) CAMEQ is based on the assumption that the hearing aid user faces the person they wish to hear and uses a free-field-to-eardrum transfer function for frontal incidence. CAMEQ2-HF is based on the assumption that the user may wish to hear sounds from many directions, and uses a diffuse-field-to-eardrum transfer function; (3) CAMEQ2-HF is based on an improved loudness model for impaired hearing; (4) CAMEQ2-HF is based on recent wideband measurements of the average spectrum of speech.

AB Temporal modulation transfer function (TMTF) is one of the most common methods for evaluating temporal acuity in the auditory system. In this experiment, we recorded cortical responses to amplitude modulation of tone carriers from implanted electrodes in guinea pigs to generate TMTFs by calculating the response amplitude changes as a function of modulation frequencies (Mfs). High-frequency hearing loss above 8 kHz was established using tone overstimulation (12 kHz, 110 dB SPL for 30 hours). The impact of this acoustic trauma on temporal resolution in the low-frequency range (below and at 8 kHz) was evaluated with the repeated tests of TMTFs until eight weeks post trauma. Deterioration in temporal resolution was found to develop over time, especially at 2 kHz, which was indicated by the decrease in -3 dB cutoffs in TMTFs and by the overall decrease in the AM response amplitude. Potential mechanisms that may underlie this off-channel affect are discussed.

DE Real-ear measurement; Hearing aid; Directivity; Directional benefit;

AB Due to individual characteristics such as head size, earmould type, and earmould venting, the directional benefit that an individual will obtain from a hearing aid cannot be predicted from average data. It is therefore desirable to measure real ear directional benefit. This paper demonstrates a method to measure real ear hearing aid directivity based on a general approach to measure the broadband output signal-to-noise ratio of a hearing aid. Errors arising from non-linearity were tested in simulation and found to be low for typical hearing aid compression ratios. Next, the efficacy of the method to estimate directional benefit was demonstrated on KEMAR. Finally the variability of directional benefit was explored in real-ears. Significant differences in signal-to-noise ratio between directional and omnidirectional microphone settings were demonstrated at most azimuths. Articulation-Index-weighted directional benefit varied by more than 7 dB across ears at some azimuths. Such individual variation in directional benefit has implications when fitting hearing aids: it should not be assumed that all users will receive similar directional benefit from the same hearing aid.

AB One of the widely used tests to evaluate functional asymmetry of cerebral hemispheres is the dichotic listening test with the usually prevailing right ear advantage. The current study aims at assessing hemispheric laterality in an adult sample of individuals with dyslexia, with auditory processing disorder (APD), and adults experiencing comorbidity of the two mentioned disorders against a control group with normal hearing and absence of learning disabilities. Results exhibit a right hemispheric dominance for the control and APD group, a left hemispheric dominance for the group diagnosed with both dyslexia and APD, and absence of dominance for the dyslexia group. Assessment of laterality was repeatable and produced stable results, indicating a true deficit. A component of auditory processing, specifically the auditory performance in competing acoustic signals, seems to be deficient in all three groups, and laterality of hemispheric functions influenced at least for auditory-language stimuli in the two of the three groups, one being adults with dyslexia and the other being adults with comorbidity of dyslexia and APD.

AB Low health literacy is reported to have negative consequences on patient understanding of health-related information: however, there is a dearth of research regarding health literacy in an audiology-specific context. This study examines the grade level of language used in verbal and written communication samples during routine hearing aid orientation appointments. Patient counseling sessions were videotaped and transcribed hearing aid instruction guides used during counseling sessions were also transcribed, The Flesch-Kincaid grade level formula was used to determine the approximate United States grade level equivalent of tire counseling sessions. hearing aid instruction guides, and to predict patient health literacy. The results indicate that patient predicted health literacy likely impacts understanding of both one-on-one counseling and hearing aid instruction guides.

AB A study of prevalence and aetiology was performed on 63 children and 127 adults in Denmark with congenital deafblindness. Using a Scandinavian definition of deafblindness, the prevalence of congenital deafblindness was found to be 1:29000. Thirty-five different aetiological causes of deafblindness were found. Causes of congenital deafblindness wen., different among adults compared to causes among children. Rubella syndrome (28%, n = 36) and Down syndrome (8%, n = 10) were the largest groups among people above 18 years of age. Among children CHARGE syndrome (16%, n = 13) was the largest group. Ethnicity was also evaluated. Among children 72% were Danish, but among the adults 98% were Danish. Implications of difference in aetiology and ethnicity are discussed in relation to the Scandinavian traditions of clinical practice and identification of congenital deafblindness.

AB Auditory processing disorder (APD) is diagnosed when a patient presents with listening difficulties which can not be explained by it peripheral hearing impairment or higher-order cognitive or language problems. This review explores the association between auditory processing disorder (APD) and other specific developmental disorders such its dyslexia and attention-deficit hyperactivity disorder. The diagnosis and aetiology of APD are similar to those of other developmental disorders and it is well established that APD often co-occurs with impairments of language. literacy, and attention, The genetic and neurological causes of APD are poorly understood, but developmental and behavioural genetic research with other disorders suggests that clinicians should expect APD to co-occur with other symptoms frequently. The clinical implications of co-occurring symptoms of other developmental disorders are considered and the review Concludes that a multi-professional approach to the diagnosis and management of APD, involving speech and language therapy and psychology its well its audiology, is essential to ensure that children have access to the most appropriate range of support and interventions.

AB The present study examined the relationship between dichotic speech recognition and state anxiety. State anxiety. as determined by, he Stale-Trait anxiety inventory (STAI), was measured pre- and post-dichotic testing in a group of young adults with normal hearing. Dichotic speech recognition was measured for three types of speech stimuli: 3-pair digits, monosyllabic words, and consonant-vowels. Results revealed significant increases in state anxiety as a function of dichotic testing for all stimulus types. There was not a significant difference, however, in suite anxiety between the stimulus types. A subset of subjects (n=44) repeated the experiment a second time. There were no significant differences in state anxiety experienced due to dichotic listening between the two sessions. Results from the present study confirm that dichotic listening induces significant increases in state anxiety in a group of young adults with normal hearing. Although statistically significant, the mean increase in state anxiety does not exceed normative levels for college students. Further. the effect of anxiety on dichotic speech recognition performance appears minimal in this population.

ID INDUCED HEARING-LOSS; RANDOM-POPULATION; NOISE; ASYMMETRY; DIP; AGE
AB It is a common misconception that high frequency audiometric notches are diagnostic of noise induced hearing loss. The aim of this study was to identify the prevalence of high frequency notch (HFN) in all audiovestibular medicine outpatient clinic population at a district general hospital. One hundred and forty nine consecutive adult patients were assessed. According to standard practice at the audiovestibular clinic, a full clinical history with particular emphasis on neuro-otological symptoms, noise exposure. and medical risk factors for sensorineural hearing loss was taken. After standard 8-frequency pure tone audiometry, subjects were divided into those with HFN and those without. There were 84 (56%) females and 65 (44%) males with a mean age of 45 years (range: 19 to 91 years). A total of 39.6% hall notches not attributable to noise (occupational or recreational) or any other known risk factor. In 29 (49.2%) and 15 (25.4%) the HFN was present in the left and right ear respectively whereas 15 (25.4%) were bilateral, The frequency least affected was 3 kHz while 4 kHz and 6 kHz were affected in almost equal proportions. In 53 ears (71.6%), the notch depth was less than 20 dBHL (10-19 dB) compared to 21 cars (28.4%) with a depth of 20 dBHL or more. This study concludes that high frequency notch without excessive noise exposure or any other known factor is common. It is neither diagnostic of, nor invariable with NIHL unless a convincing history of hazardous noise exposure is elicited front the history.

AB Knowledge regarding the variability of transient-evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) is essential in clinical settings and improves their utility in monitoring hearing status over time. In the Current Study, TEOAFs and DPOAEs were measured with commercially available OAE-equipment in 56 normally-hearing cars during three sessions. Reliability was analysed for the retest measurement without probe-refitting. the immediate retest measurement with probe-refitting, and retest measurements after one hour and one week. The highest reliability was obtained in the retest measurement without probe-refining, and decreased with increasing time-interval between measurements. For TEOAEs, the lowest reliability was seen at half-octave frequency hands 1.0 and 1.4 kHz whereas for DPOAEs half-octave frequency hand 8.0 kHz had also poor reliability. Higher primary tone level combination for DPOAEs yielded to a better reliability of DPOAE amplitudes. External environmental noise seemed to be the dominating noise source in normal-hearing subjects, decreasing the reliability of emission amplitudes especially in the low-frequency region.

AB Approximately 2-4% of newborns with perinatal risk factors present heating loss. The aim of this study was to analyse the auditory function in infants with perinatal brain injury (PBI). Brainstem auditory evoked potentials (BAEPs), auditory steady state responses (ASSRs), and tympanometry studies were carried out in 294 infants with PBI (586 cars. two infants had unilateral microtia-atresia). BAEPs were abnormal in 158 (27%) ears, ASSRs in 227 (39%), and tympanometry anomalies were present in 131 (22%) ears. When ASSR thresholds were compared with BAEPs, the assessment yielded 92% sensitivity and 68% specificity. When ASSR thresholds were compared with tympanometry results as ail indicator Of Middle-ear pathology, the assessment gave 96% sensitivity and 77% specificity. When BAEP thresholds were compared with tympanometry results, sensitivity was 35% and specificity 95%. In conclusion, BAEPs are useful test for neonatal auditory screenings they identify with more accuracy sensorineural hearing losses. ASSRs are more pertinent for identifying conducive hearing loss associated with middle-car pathology. The consistency and accuracy of these results could be considered in additional studies.

AB Current research has shown that although adult cochlear implant (CI) users generally find music to be less enjoyable following implantation. training may help some recipients to improve their music perception. This Study developed and administered a questionnaire (The University of Canterbury Music Listening Questionnaire: UCMLQ), to collect information which could then be used to develop such a music training program (MTP). One hundred adult recipients completed the UCMLQ. Results showed that respondents generally found music to be less enjoyable post-implantation, and thought that music did not sound as they would expect it to sound to a person with normal hearing. However, it was reported that Music listening could be enhanced by controlling the listening environment, being selective about die music chosen. and using a contralateral HA. The preferred logistics for a NITP were 30-minute sessions, 2-3 times Per week, using it DVD format. The program should focus on improving recipients' ability to recognize times, and encompass a wide range of musical styles. The findings support the development of a NITP for CI users to better enable them to enjoy and appreciate music, and to maximize their potential With Current technology.

AB Efforts to correlate peripheral neurophysiologic function with perceptional deficits seen in autistic disorder (AD) have resulted in mixed findings, reflecting the high degree of heterogeneity observed in these individuals. We used the auditory brainstem response to study the effect of stress (high click presentation rate) on the auditory system in 20 children with AD (7-13 years) and 20 age-matched typically developing (TD) children. We report latency prolongations in children with AD vs. TD at waves I, III, and V that differed by ear of presentation: overall, left ear showed significant prolongations by group while right ear did not. The 'stressed' condition produced prolongations for both groups at each wave. At wave V. children with AD showed significant prolongations vs. TD, particularly for the right car. For children with AD, wave V latency prolongations corresponded to language outcome as measured by VIQ. with longer prolongations associating with lower VIQ. preliminary results provide evidence for reduced Synaptic efficiency in auditory pathways in children with AD, which may form the neural bases for sensory reactivity and language impairment.

AB An elevation of the plasma arginine vasopressin (AVP) level has been frequently observed in Meniere's disease patients. However, little is known regarding the mechanism behind this elevation. The plasma AVP levels in acute phase were determined in 21 Meniere's disease patients and 16 patients with other types of vertigo, The plasma AVP levels of Meniere's disease patients in the acute phase were significantly higher than in those of other vertigo patients (p<0.01). In Meniere's disease patients with abnormally high levels of AVP (more than 3.5 pg/ml) in the acute phase, 36% of patients were resistant to conservative treatments for frequent vertigo attacks for the follow-up period of at least 2years. A significant correlation was observed between the plasma AVP in the acute phase and the highest heating threshold level at a frequency of 1 kHz for the follow-up period of at least I year (r=0.45, p<0.05). These results suggest that the elevation in plasma AVP level in the acute phase is associated with the prognosis of Meniere's disease.

AB The aim of this study was to investigate hyperacusis measurement tools and to assess the correlation between diagnostic methods for hyperacusis in daily ENT practice. We studied two hyperacusis questionnaires: the Hyperacusis Questionnaire (HQ) and the Multiple-Activity Scale for Hyperacusis (MASH), audiometric measurements (uncomfortable loudness level (ULL) and dynamic range (DR)), and the questions 'Do you have a lower tolerance for noise T and 'Are you afraid of noise?' Hyperacusis was assessed in 46 patients presenting with primary complaints of tinnitus. A validated Dutch version of the HQ is provided. A correlation was found between scores on the HQ and the MASH (p=0.000, R(2)=034). Significantly higher scores for both questionnaires were found in patients reporting decreased sound tolerance (p=0.000 and 0.002, respectively) or fear of noise (p 0.002 and 0.004, respectively). Overall, no correlations were found between scores on questionnaires and audiometric values including ULL and DR. The HQ and MASH were confirmed to be valid measurement tools for hyperacusis complaints. No correlations were found between audimetric measurements and hyperacusis complaints.

AB The aim of this study was to evaluate a clinical test proposed to verify the output setting of hearing aids. Across three test sites, 56 bilaterally fitted hearing aid users were recruited. They answered questions about real-life loudness discomfort experiences and then completed the output verification test. Using an ascending method, a 1,500 kHz narrowband noise and a selection of broadband environmental noises were presented in 5 dB steps from 80 to 90 dB SPL. Response options included 'acceptably loud', and 'uncomfortably loud'. A swept pure tone presented at 90 dB SPL was also administered. Some loudness discomfort was reportedly experienced in real life by 82% of the participants. Generally, the test noises produced low specificity, with the 1,500 kHz narrowband noise being the best predictor of loudness discomfort experiences in real life, while the swept pure tone showed low sensitivity. Individual reactions to specific sounds and the test equipment and environment used are argued to affect the laboratory performance. A better understanding of these factors is needed before the test can be improved.

AB The effect of phased caffeine withdrawal and abstention on tinnitus severity was assessed using a pseudo-randomized, double-blinded, placebo-controlled crossover trial of 30 days duration. Sixty-six volunteers who experienced tinnitus and who usually consumed at least 150 mg/day of caffeine participated. The intervention was a direct replacement of usual caffeinated tea/coffee with double-blinded supplies, under one of two conditions. Condition 1: Maintenance followed by phased withdrawal. Condition 2: Phased withdrawal followed by reintroduction and maintenance. Tinnitus severity was measured by the total score of the Tinnitus Questionnaire on Days 1, 15, and 30. Secondary measures included twice daily self-rated symptoms relevant to tinnitus and caffeine withdrawal. Caffeine had no effect on tinnitus severity, the mean difference between caffeinated and decaffeinated days being-0.04 (95% confidence interval -1.99 to 1.93), p=0.97. Significant acute adverse symptoms of caffeine withdrawal were observed. No evidence was found to justify caffeine abstinence as a therapy to alleviate tinnitus, but acute effects of caffeine withdrawal might add to the burden of tinnitus.

AB Test results and management data are summarized for 260 patients with diagnoses of Auditory Neuropathy Spectrum Disorder (ANSD). Hearing aids were tried in 85 of these patients, and 49 patients tried cochlear implants. Approximately 15% reported some benefit from hearing aids for language learning, while improvement in speech comprehension and language acquisition was reported in 85% of patients who were implanted. Approximately 5% (13/260) of the total population developed normal speech and language without intervention. Patients were diagnosed at our laboratory (n = 66) or referred from other sites (n=194), and all showed absent/grossly abnormal auditory brainstem responses (ABR), often 'ringing' cochlear microphonics, and the presence or history of otoacoustic emissions. Etiologies and co-existing conditions included genetic (n=41), peripheral neuropathies (n=20), perinatal jaundice and/or anoxia and/or prematurity (n=74). These patients comprise 10% or more of hearing impaired patients: their language acquisition trajectories are generally unpredictable from their audiograms.

AB This study explored: (1) the benefits of an FM system in real-world environments from the perspective of adults with cochlear implants, and (2) the factors and barriers to using an FM system with a cochlear implant. Using a qualitative research design, 14 adults with unilateral cochlear implants recorded their experiences during a two-month trial period with a personal FM system and responded to a questionnaire at the end of the trial. A detailed analysis of 169 journal entries (230 hours of FM use) permitted a description of the benefits and negative aspects associated with FM use in everyday listening environments. The primary benefits were related to improved access to and quality Of Sound, improved distance listening, case of listening, and better social integration. Negative perceptions were associated with the equipment both with regard to physical aspects and adjustments. In addition, technical, individual, social, and environmental factors were identified that can influence the user's decision to use the FM device. Questionnaire responses indicated that the majority of individuals rated the FM system as somewhat or very helpful. The findings suggest that FM systems can improve communication in everyday listening environments for some adults with cochlear implants.

AB It has been generally accepted that excessive exposure to loud music causes various hearing symptoms (e.g. tinnitus) and consequently leads to a risk of permanent hearing damage, known as noise-induced hearing loss (NIHL). Such potential risk of NIHL due to loud music exposure has been widely investigated in musicians and people working in music venues. With advancements in sound technology and rapid developments in the music industry. increasing numbers of people, particularly adolescents and young adults, are exposing themselves to music on a voluntary basis at potentially harmful levels, and over a substantial period of time, which can also cause NIHL. However, because of insufficient audiometric evidence of hearing loss caused purely by music exposure, there is still disagreement and speculation about the risk of hearing loss from music exposure alone. Many studies have suggested using advanced audiological measurements as more sensitive and efficient tools to monitor hearing status as early indicators of cochlear dysfunction. The purpose of this review is to provide further insight into the potential risk of hearing loss caused by exposure to loud music, and thus contribute to further raising awareness of music induced hearing loss.

AB The aim of this study was to investigate the association between maternal infection with Toxoplasma gondii IT. gondii) in pregnancy and subsequent risk of hearing loss in the offspring. The study included 27 727 children born in Norway 1992-1994, Maternal toxoplasma infection during pregnancy was ascertained by serological examination and fetal infection was ascertained by parasite detection in amniotic fluid and/or postnatal serological examination. Hearing loss was defined as mean hearing loss >35 dB HL, in the better car averaged over the pure-tone hearing thresholds at 500, 1000, and 2000 Hz, and the children were identified through linkage to the Norwegian Registry of Hearing Loss in Children. Twenty-two of the 27 727 children (0.08%) were diagnosed with hearing loss. Forty women had primary T. gondii infection in pregnancy. None of their offspring had hearing loss. There was also no association between T. gondii infection prior to pregnancy and hearing loss in the offspring. Hence, we did not find any association between T. gondii infection in pregnancy and hearing loss in the offspring.

AB This paper reports intelligibility judgments and real-life functional performance of 48 children in a double-blind, cross-over trial comparing the NAL-NL1 and the DSL v.4.1 prescriptions. Intelligibility judgments were obtained by using a paired-comparisons procedure with audio-visual stimuli. Functional performance of children during two eight-week periods, each with hearing aids adjusted to one prescription, was assessed by parents and teachers (PEACH and TEACH) and by children's self reports (SELF). Consistently across reports, performance was significantly better in quiet than in noise. On average, better performance in noise (a higher Noise subscale score) was associated with NAL-NL1 than with DSL v.4.1, both for the PEACH and the SELF. This difference was significant for the SELF in Australia. Intelligibility judgments revealed preferences that were equally split between prescriptions in both countries, on average. In the Australian sample, intelligibility judgments agreed with the questionnaire ratings and with parents' ratings. An increase in preference for NAL was significantly associated with lesser hearing loss. The effect was not significant in the Canadian sample.

AB The relative effectiveness of the NAL-NL1 and the DSL4.1 prescriptions for 48 children with mild to moderately severe hearing loss was studied using a double-blind, four-period, two-treatment cross-over design in Australia and in Canada. Evaluations included speech perception tests, loudness ratings, reports from parents and teachers on functional performance in real life, children's self-reports, paired-comparison judgements of intelligibility, and children's preferences in real-world environments. Electroacoustic measures of hearing aids revealed that gain differences dominated the comparison. Across trials and measures, individual Australian children consistently preferred either the NAL-NL1 or the DSL v. 4.1 prescription. An overall figure of merit (FOM), calculated by averaging the standardized difference scores between prescriptions for all measures, revealed that the strongest prescription-related differences were found in Australia. On average, an advantage and preference for the NAL-NL1 prescription was associated with lesser degrees of hearing loss. This research provides evidence on the effectiveness of the NAL-NL1 and DSL v. 4.1 prescriptions, and highlights the need for evaluating and fine-tuning amplification to meet the diverse needs of individual children in real life.

AB This paper examined how hearing aids adjusted for comparing NAL-NL1 with DSL v.4.1 prescription formulas matched prescriptive targets. The real-ear-to-coupler differences (RECD) of 48 children ( 24 in Australia and 24 in Canada) were measured and used to derive coupler gain targets. Verification of gain and output were carried out in an HA2-2cc coupler. Electroacoustic measurements revealed a minimal difference between NAL-NL1 and DSL v.4.1 frequency-response slopes due to practical limitations of the devices, even though the prescribed differences were large ( up to 13 dB/octave). The difference in overall gain was generally achieved in the hearing aids, with DSL v.4.1 prescribing higher overall gain than NAL-NL1. The mean RECD at 4 kHz was 5 dB higher for children in Australia than in Canada. As the same RECDs were used in deriving targets for both prescriptions, this is unlikely to affect the results of the comparison. The impact of a gain difference between prescriptions on children's performance and preferences in real life is reported in separate papers.

AB This document describes the national protocol for the selection, fitting, verification, and evaluation of amplification for hearing-impaired children in Australia. It also outlines the approach to management of children who have auditory neuropathy spectrum disorder, children who have mild and unilateral hearing loss, and children who require cochlear implantation. Audiological management of all Australian citizens and permanent residents under twenty-one years of age who have a hearing loss is carried out by the national hearing service provider, Australian Hearing. It is funded by the Australian Government's Hearing Services Program to provide fully subsidised hearing aids, frequency modulated ( FM) systems and ongoing audiological management. All hearing aids for children are multi-channel devices that offer wide dynamic range compression, directional microphone technology and feedback cancellation as well as access to multiple listening programs, telecoil and audio-input facilities. Hearing aid gain, frequency response and maximum power output are derived according to the NAL-NL1 prescription procedure and verified using real ear measurements. Amplification benefit is evaluated using a range of speech perception tests and functional assessment questionnaires.

AB This paper reports real world preferences of children in a double-blind, cross-over trial comparing NAL-NL1 and DSL v.4.1 prescriptions. Twenty-four children wore digital WDRC hearing aids at each site ( Australia, Canada). Multi-memory hearing aids provided the NAL and DSL programs in each of two memories. Diaries were completed during two counterbalanced trials, providing overall preference, situational preference, and preference comments. Ratings were reliable, and situational preferences factored into quiet/low level situations versus noisy/reverberant/high level situations. Children at both sites used DSL v4.1 for hearing low level speech, or when they wanted to hear loudly and clearly. Children used NAL-NL1 when they wished to hear sounds at a lower level, or to reduce background noise. Children expressed strong preferences for having the choice of both programs. Canadian children were more likely to prefer DSL than were the Australian children. Factors such as listening environment and prior listening experience are discussed in interpreting these findings.

AB This paper reports speech and loudness measures on a group of children in a double-blind cross-over trial comparing the NAL-NL1 and DSL[i/o] prescriptions. Twenty-four children with hearing impairment were fitted with digital WDRC hearing aids at each site ( Australia, Canada). Speech recognition was measured for nonsense syllables and for the 50% correct threshold for sentence recognition in noise. Loudness ratings for sentences were made on a 7-point scale. Measures were made at fitting and repeated following 8-week trials. Fitting orders were randomized and counterbalanced. Significant differences in consonant recognition occurred for individual children. On average, scores at the 80 dB SPL presentation level were better with the NAL-NL1 fitting. Loudness ratings differed at baseline but did not differ following home trials. Speech recognition scores revealed a small but significant interaction of prescription with level in quiet but not in noise. Individual children had significant performance differences. Loudness ratings showed significant acclimatization effects for children at both sites.

AB Choice of the most appropriate car for CI in postlingually hearing-impaired adults is becoming more relevant as more patients are considered eligible for intervention. The aim of this stud), is to review factors that influence this choice and to formulate a flowchart. An extensive Medline search was performed. Factors can be divided into surgical, audiological. and patient factors. Surgical factors are anatomic variation and otological medical history. Both are divided in absolute and relative contra-indications. Duration of deafness and residual hearing are combined in the audiological factor. Likeliness of improvement of speech perception after CI at different durations of deafness is estimated. This is followed by comparison of between-car differences in duration of deafness. If there is a large difference, above the presented 5% interval, the car with the shortest duration is preferred. This review and its flowchart are an aid for decision making in the choice of ear for CI. Being as representative of current knowledge as possible, future refinements may occur as new insights are gained.

AB Pure-tone thresholds were used as the reference and compared with extrapolated distortion product otoacoustic emission input/output-functions and auditory steady state responses (ASSR) in hearing-impaired adults, using the Cochlea-Scan and Ancient devices. Fifty-three subjects presenting sensorineural deficits were included in the study. The DPOAE data were recorded using the detailed Cochlea-Scan threshold modality, and ASSR responses were assessed at 1.0. 2.0, and 4.0 kHz. The comparison between DPOAE and ASSR threshold values indicated significant mean differences across all tested frequencies. Significant relationships were observed between the behavioral and the DPOAE measurements in the lower frequencies (1.5 and 2.0 kHz). The Cochlea-Scan algorithm seems to overestimate hearing threshold. Logistic regression models (probability of DPOAE response p = 0.9), suggested that the identifiable hearing levels are less than 34 dB HL (at 2.0 and 4.0 kHz) and less or equal to 38 and 40 dB HL at 1.5 and 6.0 kHz respectively The Cochlea-Scan DPOAE protocols can be used in cases presenting mild hearing deficits (i.e. <40 dB HL).

AB This study evaluated prototype multichannel nonlinear frequency compression (NFC) signal processing on listeners with high-frequency hearing loss. This signal processor applies NFC above a cut-off frequency The participants were hearing-impaired adults (13) and children (11) with sloping. high-frequency hearing loss. Multiple Outcome measures were repeated using it modified withdrawal design. These included speech sound detection, speech recognition. and self-reported preference measures. Group level results provide evidence of significant improvement of consonant and plural recognition when NFC was enabled. Vowel recognition (lid not change significantly Analysis of individual results allowed for exploration of individual factors contributing to benefit received from NFC processing. Findings Suggest that NFC processing can improve high frequency speech detection and speech recognition ability for adult and child listeners. Variability in individual outcomes related to factors such as degree and configuration of hearing loss. age of participant, and type of outcome measure.

AB This study investigates the effect of the Nucleus CI24RE implant's neural response telemetry (NRT) system. which has less internal noise compared to its predecessor, the CI24M/R implant. on the NRT threshold (TNRT) profile across the array. CI24M/R measurements were simulated by ignoring CI24RE Measurements with response amplitudes below 50 uV Comparisons of the estimated TNRTs from the CI24RE measurements and the CI24M/R simulations Suggest that, apart front a constant level difference. the TNRT profiles from the newer implant generally would not have differed very much from those of its predecessor. This view was also reflected by principal component analysis (PCA) results which revealed a 'shift' component similar to that reported by Smoorenburg et al (2002). On the whole, there is no indication that current practices of using the TNRT profiles for assisting with speech processor programming need to be revised for the CI24RE implant.

AB This longitudinal study investigated how chronic gunshot noise exposure affects cochlear and saccular function in police officers who engaged in regular target shooting practice using dual protection (car plugs plus earmuffs) for > 10 years. In 1997. 20 male police officers underwent audiometry before and two weeks after shooting. Twelve of the original subjects were re-examined by audiometry coupled with vestibular evoked myogenic potential (VEMP) test in 2007. Significant deterioration of mean hearing thresholds at Frequencies of 500 Hz through 4000 Hz was noted ten years later. affecting both ears. However, only the frequencies of 4000 and 6000 Hz on he left car revealed significant difference in mean hearing thresholds compared with healthy controls. Abnormal VEMP responses were evident in nine police officers (75%). including absent VEMPs 7 and delayed VEMPs 2. In conclusion, deterioration to hearing may occur after long term exposure to gunshots, even when double hearing protection is used. Further study is in progress regarding how to preserve both cochlear and saccular function during long term gunshot exposure.

AB Musician earplugs are marketed and recommended For use in music settings but no studies have evaluated these products with musicians. This study evaluated the influences of earplugs on college Students' perception and abilities to communicate in a musical environment. attitudes of carplugs, comfort over time, and file influence of earplugs on ability to play music. College students (N = 323) were provided with earplugs for use during and following all experimental condition designed to mimic a night club. Results underline the challenges of earplugs in environments that are both tend and require verbal interaction. Responses to comfort questions were variable and suggest a multi-factorial set of influences that may include intrinsic variables. Despite these limitations. subjects in this Study generally liked the earplugs and believed that they are valuable. However, the earplugs were not viewed favorably by musicians willing to use the earplugs while playing music. This Study Supports the view that earplugs are subject to many problems and should be considered as a last resort.

AB This research aimed at describing satisfaction with hearing aids From the perspective of the client as a consumer. A disconfirmation-expectancy new model. derived from consumer research. was evaluated. This model posits that pre-fitting expectations. post-fitting performance and the experience of flow performance compares to expectations (disconfirmation), contribute to satisfaction. Positive disconformation occurs when performance is better than original expectations and is associated with higher satisfaction. Negative disconfirmation is when performance is poorer than expectations and is associated with dissatisfaction. New hearing aid users in Hong Kong (N=42) were tested with a newly developed self-report measure (PHACS: profile of hearing aid consumer satisfaction) that included items focused oil hearing ability, problems, cost, and service. Pre-fitting expectations and post-fitting performance, disconfirmation, and satisfaction were measured. Results showed that expectations were generally not related to satisfaction, that disconfirmation was correlated with many aspects of Satisfaction, and that performance was most strongly related to satisfaction. The implications of the findings are that healing aid performance is the most important clement tor determining, satisfaction: however disconfirmation should not be overlooked.

AB This study tested a theoretical model of tinnitus-related distress and of general distress that involved acceptance of tinnitus symptoms and emotional intelligence as factors that May Protect against Such distress. One hundred and sixty-two tinnitus sufferers from throughout Australia completed measures of acceptance of tinnitus, symptoms. emotional intelligence. tinnitus-related distress, and general distress. As hypothesized, greater acceptance of tinnitus symptoms was associated with less tinnitus-related distress Emotional intelligence was not associated with tinnitus distress. Greater acceptance and less tinnitus distress were both associated with less general distress. and the association between acceptance and general distress was mediated by tinnitus-related distress. The findings, which provide partial support for the tested model. may have implications for efforts to assist distressed tinnitus sufferers.

AB The aim of this study was to develop Polish sentence tests for accurate measuring of speech intelligibility in masking interfering noise. Two sets of sentence lists have been developed. The first set was composed of 25 lists and was used for sentence intelligibility scoring. The second set was composed of 22 lists and was used for word intelligibility scoring. The lists in each set have been phonemically and statistically balanced. The speech reception threshold (SRT) and slope of the psychometric function at the SRT point (S(50)) were determined in normal-hearing subjects. It was found that the mean SRT and mean list-specific S(50list) for the first set were equal to -6.1 dB and 25.5%/dB, respectively. The mean SRT and the mean list-specific S(50list) for the second Set were: -7.5 dB and 20.8%/dB. Due to a relatively steep slope of the psychometric functions, the Polish sentence tests were shown to he accurate materials for speech intelligibility measurements against interfering noise They are file first sentence speech-in-noise tests developed for Slavonic languages.

AB Digital noise reduction systems in modern digital hearing aids aim to improve either speech intelligibility or listening comfort. Little is known. however, about the actual gain reduction produced by different noise reduction systems. The aim of this study is to compare the gain reduction of different noise reduction systems. We applied a systematic variation of different Presentation levels of the input signal, different signal-to-noise ratios. and different target hearing loss configurations. The gain reduction of 12 different hearing aids writs compared both qualitatively and quantitatively by means of principal value decomposition.
   The results show that these hearing aids differ considerably in their responses. These differences are presented qualitatively by Plotting contour maps that give the gain reduction its function of signal-to-noise-ratio and Frequency. The quantitative analysis show that the gain reduction produced by most hearing, aids can be characterized by two transfer functions. The most important being,in overall gain reduction. In addition to this, the frequency response is tilted to achieve either more low-frequency reduction and less high-frequency reduction, or the opposite.

AB This study addresses the ultrastructural and functional damage and subsequent recovery of the inner ear in the Atlantic cod following intrasaccular gentamicin injection. Inner car damage was assessed using SEM and measurements of AEP following 250-Hz pure-lone stimuli. Data from gentamicin-treated fish were compared with control (no injection) and sham (injection of saline) fish. Control fish had normal response thresholds associated with well-developed hair cell bundles in their macula sacculi. Strain fish had higher response thresholds compared with control fish during the First week post-intervention, but response thresholds were subsequently normal. Treated fish displayed significant inner car damage associated with all increased average AEP threshold on the third day following treatment. Thereafter. inner car tissue displayed signs of progressive regeneration until it was comparable to controls from the 14th day. Response thresholds were similar to those of control Fish from the 17th day following treatment. These observation Suggest that the macula sacculi of Atlantic cod call regenerate toward's it near-complete functional and ultrastructural recovery within 17-21 days Following ototoxic gentamicin treatment.

AB The objective of this study was to estimate the prevalence Of hearing impairment ill four genetically isolated Italian villages (Carlantino, Campora, Gioi-Cardile, and Stoccareddo), 1682 subjects were recruited from all the individuals participating in a multidisciplinary study. They underwent otoscopy and pure-tone audiometry and completed it questionnaire. The audiological data show that the percentage of impaired people increases with age and ill particular becomes relevant aged over 40. For this reason we decided to compare the PTA values of individuals aged 40 or older. The PTA values, of Stoccareddo and Carlantino are statistically different front PTAs of the other villages. Campora and Gioi-Cardile. both located within the Cilento National Park, have similar middle-low frequency PTA values while sonic differences are present at high frequencies. Using pedigrees it was possible to calculate the heritability of the trait. For Carlantino and Gioi-Cardile the percentage of the phenotype variation attributable to genetic variation is not significant. while for Campora file heritability value is 0.49 (p = 0.01) suggesting, that genetic factors may have an important role.

AB A data bank of prevalence of hearing impairment tor monitoring and implementation of programmes in national or global level and for the estimate of the global burden hits been established. A systematic search was conducted of random-sample population-based studies of bilateral hearing impairment with clearly defined hearing threshold levels. Fifty-three studies from 31 countries from all WHO regions were found to meet the selection criteria. The prevalence of mild and disabling hearing impairment and other details from the studies are reported by WHO region. Although a large number of studies were found. only a small number among them were suitable surveys of prevalence of bilateral hearing impairment in the general population. Hearing impairment is it major disability that should he monitored at all ages: more population-based surveys are needed ill all regions of the world. Utilization of the WHO protocol is recommended for collection and analysis of data in standard ways; especially recommended is the use of WHO threshold levels and to report the prevalence of bilateral impairment. both of which required to calculate burden.

AB The aim of this study wits to assess the receptive language and speech production abilities of it group of school-aged children with auditory neuropathy/dys-synchrony-type hearing loss, Ten children who had received it cochlear implant in one or both cars participated. Findings for this group were compared with those for a matched cohort of implanted children with other forms of sensorineural hearing loss and with those for a group of auditory neuropathy/dys-synchrony children who were long-term hearing aid users.
   Results for 9 of the ten implanted children with auditory neuropathy/dys-synchrony were similar to those of the general population of paediatric implant recipients. (One child, who gained little perceptual benefit from his device, showed severely delayed spoken language development). Results for the group of aided auditory neuropathy/dys-synchrony subjects were comparable to those for their implanted counterparts suggesting that affected children should not automatically be considered cochlear implant candidates.

AB This preliminary study examined the effects of hearing loss and aging on the detection of AV asynchrony in hearing-impaired listeners with cochlear implants. Additionally, the relationship between AV asynchrony detection skills and speech perception was assessed. Individuals with normal-hearing and cochlear implant recipients were asked to make judgments about the synchrony of AV speech. The cochlear implant recipients also completed three speech perception tests, the CUNY. HINT sentences, and the CNC test. No significant differences were observed in the detection of AV asynchronous speech between the normal-hearing listeners and the cochlear implant recipients. Older adults in both groups displayed wider timing windows, over which they identified AV asynchronous speech its being synchronous, than younger adults. For the cochlear implant recipients, no relationship between the size of the temporal asynchrony window and speech perception performance was observed. The findings from this preliminary experiment suggest that aging has a greater effect oil the detection of AV asynchronous speech than the use of a cochlear implant. Additionally, the temporal width of the AV asynchrony function was not correlated with speech perception skills for hearing-impaired individuals who use cochlear implants.

AB Listeners with high-frequency dead regions (DRs) benefit from amplification of frequencies up to 1.7 times the edge frequency, f(e), of the DR. Better consonant identification might be achieved by replacing the band from f(e) to 1.7f(e) with a higher spectral band. We aimed to identify the optimal band, using simulations with normal-hearing listeners. In experiment 1, nonsense syllables were lowpass filtered to simulate DRs with f(e) of 0.5, 0.75, and 1.0 kHz. Identification was measured for each of these base bands alone and with a bandpass-filtered band added (but not transposed). The added band either extended from f(e) to 1.7f(e) or its center frequency was increased, keeping bandwidth fixed in ERB(N)-number. Performance improved with increasing center frequency and then reached an asymptote or declined. Experiment 2 used a mid-frequency base band. and a lower-frequency added band. The results also showed a beneficial effect of frequency separation of the added and base bands. Experiment 3 resembled experiment 1, but with bandwidth Fixed in Hertz. For higher-frequency added bands, the benefit was lower than for experiment 1.

AB Audiometric characteristics of a recently introduced more powerful, behind-the-ear, BAHA sound processor, the BAHA Intenso, were evaluated in 23 patients with contra-indications for using conventional hearing aids. All patients had mixed hearing loss with boneconduction thresholds ranging between 30 and 50 dB HL. Boneconduction gain, defined as the difference in aided free-field detection thresholds and unaided boneconduction thresholds, was calculated at the octave frequencies between 500 Hz and 4 kHz. Median boneconduction gain of the Intenso ranges from 0 dB at 500 Hz to 12 dB at 2 kHz with substantial interindividual variability. The upper limit of the BAHA Intenso's fitting range was established by requiring aided speech reception thresholds with CVC-monosyllables of at most 60 dB SPL. The fitting range of the BAHA Intenso appeared to be limited to 42, 44, 58, and 48 dB HL for boneconduction thresholds at 0.5, 1, 2, and 4 kHz, respectively. Loudness growth functions at 0.5 and 3 kHz as obtained with 7-point categorical scaling showed an adequate aided dynamic range.

AB This study examined the effects of extending high-frequency bandwidth, for both a speech signal and a background noise, on the acceptable signal-to-noise ratio (SNR) of listeners with mild sensorineural hearing loss through utilization of the Acceptable Noise Level (ANL) procedure. In addition to extending high-frequency bandwidth. the effects of reverberation time and background noise type and shape were also examined. The study results showed a significant increase in the mean ANL (i.e, participants requested a better SNR for an acceptable listening situation) when high-frequency bandwidth was extended from 3 to 9 kHz and from 6 to 9 kHz. No change in the ANL of study participants was observed as a result of isolated modification to reverberation time or background noise stimulus. An interaction effect. however, of reverberation time and background noise Stimulus was demonstrated, These Findings may have implications for future design of hearing aid memory programs for listening to speech in the presence of broadband background noise.

AB GJB2 mutations are major causes of autosomal recessive nonsyndromic hearing loss (ARNSHL) in many populations. However, a few mutations have an ethnic-specific background. We performed it review by means of a meta-analysis to evaluate the influence of the 35delG on ARNSHL. A PubMed, InterScience, British Library Direct, and Sciencedirect search using keywords '35delG', 'GJB2' and 'Connexin 26' associated with 'carrier frequency' was carried Out to include all papers front February 1998 to February 2008. 35delG carrier frequencies in 23187 random controls were analysed and categorized, corresponding with geographical boundaries, from all over the world. Mean carrier frequencies of 35delG mutation were found to be 1.89, 1.52, 0.64, 1, and 0.64 for European, American, Asian, Ocean, and African populations, respectively. We round that the average 35delG carrier frequency is highest in southern Europe and lowest in eastern Asia. The south-to-north European gradient in the carrier frequency of 35delG was confirmed and also a west-to-east Asian gradient is suggested. This study highlights the importance of establishing prevalence. based on the local population for screening and diagnostic programs of live births.

AB Children with auditory processing disorders (APD) were fitted with Phonak EduLink FM devices for home and classroom use. Baseline measures of the children with APD, prior to FM use, documented significantly lower speech-perception scores, evidence of decreased academic performance, and psychosocial problems in comparison to an age- and gender-matched control group. Repeated measures during the school year demonstrated speech-perception improvement in noisy classroom environments as well as significant academic and psychosocial benefits. Compared with the control group, the children with APD showed greater speech-perception advantage with FM technology Notably, after prolonged FM use, even unaided (no FM device) speech-perception performance was improved in the children with APD, suggesting the possibility of fundamentally enhanced auditory system function.

AB Transposition of acoustic information from higher to lower frequencies may help people with severe or profound high-frequency hearing loss, especially when a 'dead region' is present. Previously, we (Robinson et al. 2007) evaluated the benefit of an FFT-based transposition algorithm in a laboratory study. Although results were promising, we hypothesized that further training and exposure would be needed to gain the full benefit. This was tested here by implementing the algorithm in wearable digital hearing aids. Five subjects with high-frequency dead regions used the aids for five weeks. Performance on the transposing and control conditions was compared objectively using speech tests (vowel-consonant-vowel, 's' detection, and speech in noise) and subjectively using questionnaires. Overall, the results showed no benefit with the transposition even after experience. Subjective preference was generally for the control condition.

AB The objective of this study was to investigate the effect of tightened hearing protection regulations on tinnitus in the Finnish Defence Forces. The initial study group comprised 252 officers and non-commissioned officers (NCOS), of which 229 were included in the final study group. Subjective symptoms of tinnitus and audiometric test results for these officers and NCOs examined before retirement, from 1984 to 1986 (Period 1), and 2003 to 2005 (Period 11), were reviewed. Changes in tinnitus reports between the two time periods. during which regulations had been revised, were investigated. Prevalence of tinnitus showed a decline both in officers (from 68% to 63%) and in NCOs (from 76% to 72%) between the two study periods, in accordance with tightened hearing protection regulations. The Cox regression analysis showed a significantly decreased hazard ratio for constant or disturbing tinnitus for Period II. Tinnitus prevalence, especially constant or disturbing tinnitus, in the Finnish Defence Forces was diminished by tightened hearing protection regulations. Tinnitus might be more persistent than hearing loss and does not necessarily improve in direct relation to hearing loss after protective measures.

AB Modern cochlear implant systems deliver impulse transmission rates up to 50 000 pps. It emerged that the fast stimulation rates led to enhanced speech comprehension. Impedance measurement is an important aspect in cochlear implant testing procedures. Impedance values are a measure of the electrical resistance between the individual implant electrodes. Increased impedances were attributed frequently to inflammatory/tissue-related processes. In recent years, however we have repeatedly found cases of impedance increase for which the inflammatory model did not provide a satisfactory explanation. The aim of this study is to evaluate increases in impedance in our cochlear implant population, to attempt to find their cause, and to formulate therapeutic hypotheses. In our cochlear implant programme (> 3000 recipients) we screened our database for impedance increases over time during device fitting. We found 16 patients with 18 affected ears in whom impedance increases were clearly demonstrated. We found that especially in cases without any sign of prior inflammation, increasing the pulse width of the stimulation strategy seems to be an effective tool to return increases impedances to normal levels.

AB The purpose of this study was to examine patterns of energy of reflectance (ER) in preoperative and postoperative conditions in otosclerotic ears. It was also within the scope of this paper to investigate whether the changes in ER pattern post-operatively correlate to the improvement in hearing its measured by pure-tone audiometry. ER was measured in 15 surgically confirmed otosclerotic ears (mean age: 44 years) before and after the stapes surgery. The most prominent change in ER pattern following the surgery in majority of the subjects was a sharp and deep drop in ER value between 700-1000 Hz. There was also a secondary wider and smaller increase in ER value following the surgery between 2000-4000 Hz. Moreover, in most cases the drop in ER values following the surgery in low frequencies (<= 1000 Hz) approximated the mean ER values in the normal group. Comparison of ER patterns with hearing improvement as measured by air conduction averaged across low (250-1000 Hz) and high (2000-6000 Hz) frequency hands before and after the surgery did not reveal any significant correlation. However, there was a general positive correlation trend for ER changes in low frequency band and AC changes. especially for high frequency bands. Changes in ER pattern may potentially be useful as an objective tool for monitoring the impact of the stapes reconstructive surgery and evaluating different surgical protocol.

AB The goal of this study was to examine the relationships between scores obtained from measures of speech perception and language in a group of young children with hearing loss (HL). Eighteen children (mean age = 4.3 years)and their mothers participated in this study. Speech perception was measured using the online imitative test of speech pattern contrast perception (OLIMSPAC). Standardized language age equivalent scores were obtained using the Reynell developmental language scales-[1]. Number of word tokens, word types, and mean length of utterance (MLU) were extracted from the children's spontaneous language samples. Significant positive relationships were observed between children's OLIMSPAC scores and both standardized language scores (r ranging from 0.60 to 0.69; p < 0.01) and all measures derived from children's spontaneous language samples (r ranging from 0.80 to 0.86; p < 0.01). After controlling for child age, OLIMSPAC scores explained 34.1% of the variance in children's MLU. Using a new speech perception measure with reduced language demands, strong positive correlations were evident between speech perception and language skills for a young group of children with HL.

AB English-as-a-second-language (ESL) listeners have difficulty perceiving English speech presented in background noise. The current study furthered this line of investigations by including participants who varied widely in their age of English acquisition and length of English learning: 24 native English monolingual (EML). 12 simultaneous bilingual (SBL). 10 early ESL (E-ESL), and 14 late ESL listeners. Word recognition scores were obtained in quiet and in the presence of speech-weighted noise, multi-talker babble, forward-playing music, and time-reversed music. All words and competing signals were presented at 45 dB HL. EML and SBL listeners' performances were found to be similar across test conditions. ESL, especially L-ESL listeners, performed significantly EML and SBL listeners. Overall, speech-weighted noise and multi-talker babble showed greater masking effect than music; however, the difference in performance between L-ESL and EML listeners was the largest for the music maskers, indicating that L-ESL listeners are susceptible to weaker maskers. Age of acquisition and length of learning were both shown to be good indicators of SBL and ESL listeners' performance.

AB Hearing threshold sound pressure levels were measured for the Sennheiser HDA 280 audiometric earphone. Hearing thresholds were measured for 25 normal-hearing test subjects at the 11 audiometric test frequencies from 125 Hz to 8000 Hz. Sennheiser HDA 280 is a supra-aural earphone that may be seen as a substitute for the classical Telephonics TDH 39. The results are given as the equivalent threshold sound pressure level (ETSPL) measured in an acoustic coupler specified in IEC 60318-3. The results are in good agreement with an independent investigation from PTB, Braunschweig, Germany. From acoustic laboratory measurements ETSPL values are calculated for the ear simulator specified in IEC 60318-1. Fitting of earphone and coupler is discussed. The data may be used for a future update of the RETSPL standard for supra-aural audiometric earphones, ISO 389-1.

AB We studied the relationship between tinnitus pitch and the audiogram in 195 patients. Patients with tone-like tinnitus reported a higher pitch (mean = 5385 Hz) compared to those with a noise-like quality (mean = 3266 Hz). Those with a flat audiogram were more likely to report: a noise-like tinnitus, a unilateral tinnitus, and have a pitch < 2000 Hz. The average duration of bilateral tinnitus (12 years) was longer than that of unilateral tinnitus (5 years). Older subjects reported a less severe tinnitus handicap questionnaire score. Patients with a notched audiogram often reported a pitch <= 8000 Hz. Subjects with normal hearing up to 8000 Hz tended to have a pitch >= 8000 Hz. We failed to find a relationship between the pitch and the edge of a high frequency hearing loss. Some individuals did exhibit a pitch at the low frequency edge of a hearing loss, but we could find no similar characteristics among these subjects. It is possible that a relationship between pitch and audiogram is present only in certain subgroups.

AB The purpose of this study was to investigate the role of anxiety sensitivity and behavioral avoidance in tinnitus distress and functioning. A cross-sectional sample of 283 individuals experiencing tinnitus was obtained from an epidemiological national survey study on hearing loss, dizziness, and tinnitus. The subjects completed a series of questionnaires measuring anxiety sensitivity, anxiety, and depression. They also answered questions regarding tinnitus distress, functioning, and avoidance. Results revealed a positive significant correlation between anxiety sensitivity and tinnitus distress. This relationship was not better explained by anxiety and depression symptoms. In addition, the findings provided support for a model where behavioral avoidance fully mediated the relationship between anxiety sensitivity and tinnitus functioning, and partially mediated the relationship between anxiety sensitivity and tinnitus distress. Implications for the role of anxiety sensitivity and behavioral avoidance in tinnitus research are discussed

AB In this study, monosyllabic Mandarin speech test materials (MSTMs) were developed for use in word recognition tests for speech audiometry in Chinese audiology, clinics Mandarin monosyllabic materials with high familiarity were designed with regard to phonological balance and recorded digitally with a male voice. Inter-list equivalence of difficulty was evaluated for a group of 60 subjects (aged 18-25 years) with normal hearing. Seven lists with 50 words each were found to be equivalent. These seven equivalent lists were used to measure performance-intensity (PI) functions for a group of 32 subjects with normal hearing and a group of 40 subjects with mild to moderate sensorineural hearing loss. The mean slope of PI function was found to be 4.1%/dB and 2.7%/dB, respectively. The seven lists of Mandarin monosyllabic materials were found to have sufficient reliability and validity to be used in clinical situations.

AB In this study we asked to what extent auditory evoked potentials can help us to understand the complex processes underlying word comprehension. Monosyllabic and bisyllabic words were presented to 34 young adults in the context of a semantic category judgment. The basic paradigm assessed the typicality effect, the tendency for classification of members of a category to be made more accurately and more rapidly for strong exemplars than for weak exemplars. Event-related potentials (ERPs) were recorded from 30 active scalp electrodes. The ERP waveform in response to the semantic categorization of a word was characterized by unique activity in four temporal intervals; (1) a negative peak at a latency of about 100 ms, (2) a positive peak at a latency of about 200 ms, (3) a broad negativity extending over the latency range from 200 to 600 ms, and (4) a broad positivity extending from 600 to 1400 ms. Independent component analysis (ICA) of the individual EEG epochs yielded four maximally independent components, interpreted as (1) exogenous detection of a change in the acoustic environment, followed by allocation of cognitive resources, especially sustained attention, to the analysis of subsequent acoustic events, (2) phonological processing, (3) semantic processing, and (4) decision processing. The morphologies of the four ICA waveforms were consistent with a parallel processing, interactive model of word recognition, and subsequent semantic categorization.

AB The aim of this study was to describe the clinical features of hearing loss due to mutations on connexin 26/30 coding genes (GJB2/GJB6). Mutations in the GJB2 gene are found to account for approximately 50% of cases of autosomal recessive non-syndromic deafness. Several European studies have estimated that the GJB2 healthy carrier condition involves about 2-4% of the population, with the 35delG mutations being the most common. A 342-kb deletion truncating the GJB6 gene (encoding connexin-30) has been associated with autosomal recessive non-syndromic deafness, mostly as digenic inheritance of the Cx30 deletion/Cx26 mutation. The following retrospective study describes audiological features and genotypes of a large cohort of 376 Italian hearing-impaired patients who underwent genetic screening for the GJB2/GJB6 genes and received follow-up care at our centre between January 2002 and October 2006. Sixteen different genotypes causing deafness in more than 27% of patients with either biallelic mutations or digenic inheritance GJB2/GJB6 were identified. The most frequent mutations were 35delG, M34T, L90P, and R184P.

AB Salicylate, a common drug frequently used long term in the clinic, is well known for causing reversible hearing loss and tinnitus. Our previous study, however, demonstrated that chronic administration of salicylate progressively raised the amplitude of distortion product of otoacoustic emissions (DPOAEs), which are mainly caused by (outer hair cell) OHC electromotility. How salicylate affects OHC electromotility to cause this paradoxical increase remains unclear. One possibility is that it could affect prestin, which is a motor protein that contributes to the mechano-electrical properties of OHCs. In this experiment, we assessed the effect of acute and chronic salicylate treatment on prestin expression. Interestingly, after long-term salicylate injection (200 mg/kg, twice daily for 14 days), prestin gene and protein levels were up-regulated about twofold. These levels returned to baseline 14 days after treatment stopped. Acute injection of salicylate (single injection, 400 mg/kg) did not affect prestin levels. These data reveal that chronic salicylate administration markedly, but reversibly, increased prestin levels which may contribute to the enhanced DPOAE amplitudes we observed previously with similar salicylate treatment, which may be responsible for salicylate-induced tinnitus generation.

AB A prototype self-report measure of vestibular rehabilitation outcome is described in a previous paper. The objectives of the present work were to identify the most useful items and assess their psychometric properties. Stage 1: One hundred fifty-five participants completed a prototype 36-item Vestibular Rehabilitation Benefit Questionnaire (VRBQ). Statistical analysis demonstrated its subscale structure and identified redundant items. Stage 2: One hundred twenty-four participants completed a refined 22-item VRBQ and three established questionnaires (Dizziness Handicap Inventory, DHI; Vertigo Symptom Scale short form, VSS-sf; Medical Outcomes Study short form 36, SF-36) in a longitudinal study. Statistical analysis revealed four internally consistent subscales of the VRBQ: Dizziness, Anxiety, Motion-Provoked Dizziness, and Quality of Life. Correlations with the DHI, VSS-sf, and SF-36 support the validity of the VRBQ, and effect size estimates suggest that the VRBQ is more responsive than comparable questionnaires. Twenty participants completed the VRBQ twice in a 24-hour period, indicating excellent test-retest reliability. The VRBQ appears to be a concise and psychometrically robust questionnaire that addresses the main aspects of dizziness impact.

AB The purpose of this study was to examine the effects of altering the fundamental frequency (F0) on perception of prosody and speaker gender in both normal-hearing listeners and cochlear implant (CI) recipients. Tests with natural speech and defined modifications of the F0 were performed, and the resulting changes in perception were measured. Compared to the normal-hearing listeners, most of the CI users exhibited worse outcomes, especially for sentence stress. In contrast, the speaker gender tests yielded similar results for both groups when artificially modifying the F0 contour. The results seemed to be strongly related to the duration of alterations in F0. Although the perception of prosodic cues was limited in most of the CI recipients, they showed qualitatively similar results to normal-hearing listeners in that the boundary between questions and statements and between female and male voices was comparable. A large inter-individual difference in performance was observed among the CI recipients, which could not be attributed to different processor or implant types or to other factors such as implant experience.1.

AB The effect of the level of threshold equalizing noise (TEN) on the diagnosis of dead regions (DRs) was investigated. Participants comprised 23 adults with sensorineural hearing impairment. Masked thresholds were measured monaurally with TEN at 60, 70, 80, and 90 dB HL/ERBN. Absolute and masked thresholds (with TEN at 80 dB HL/ERBN) were retested. The diagnosis was unaffected by TEN level at any frequency for eight of the 13 participants who met the criteria for a DR. For four of the latter, increasing the TEN level changed the diagnosis from DR to no DR, mainly at 1.5 kHz, corresponding to the edge frequency, fe, of the DR. For one participant with a low-frequency DR, increasing the TEN level changed the diagnosis from no DR to DR, only at 1 kHz. The changes with level were too large to be explained in terms of test repeatability. Overall, the results of the TEN test are usually not affected by TEN level, except for test frequencies close to fe when absolute thresholds are near-normal for frequencies adjacent to fe.

AB The fitting of a cochlear implant together with aided residual hearing was evaluated by means of matching frequency and/or perceived pitch between acoustic and electric modalities. Five cochlear implant users with the Nucleus Freedom electrode array with residual acoustic hearing participated. Psychophysical procedures were used to create a map in which the implant was programmed to provide the listener with high-frequency information only above the frequency at which acoustic hearing was no longer considered useful. This was compared to a second map which provided the full frequency range. Listeners wore each map for a number of weeks before speech recognition was measured in quiet and noise. Post-operatively across subjects, average hearing thresholds worsened by 27 dB. However, cochlear implantation provided superior recognition of speech compared to pre-operative scores, with the best results found when subjects were wearing their hearing aids together with the implant. No significant differences were found between the two maps on speech tests when subjects were wearing their implant together with hearing aid/s. In conclusion, the combination of a cochlear implant together with hearing aid/s was effective at providing speech perception benefits for the listeners of the current study, regardless of the frequency-to-electrode allocation selected.

AB The objective of this study was to investigate trends in the referral process among pediatric cochlear implant candidates. Medical and audiologic charts between 2003 and 2005 were reviewed, and children five years and younger with moderately-severe or worse sensorineural hearing loss were included. Of the 105 audiograms meeting the inclusion criteria, 69% were referred for a cochlear implant, and 52% were considered as definite candidates for an implant by audiologists with expertise in cochlear implant technology. Children referred for an implant, compared to children who were not referred, were more likely to have married parents (91% vs. 70%, p=0.02) and more likely to have private insurance (56% vs. 29%, p=0.02). Multivariable regression results were consistent with the unadjusted findings regarding marital status, but not insurance status. Children with sensorineural hearing loss are inconsistently referred to cochlear implant teams despite similar audiologic findings. To reach the Healthy People 2010 goals, this disparity should be addressed. A further understanding of the population of children not referred is important in diminishing inconsistencies and understanding barriers to care.

AB Speech reception tests are commonly administered by manually scoring the oral response of the subject. This requires a test supervisor to be continuously present. To avoid this, a subject can type the response, after which it can be scored automatically. However, spelling errors may then be counted as recognition errors, influencing the test results. We demonstrate an autocorrection approach based on two scoring algorithms to cope with spelling errors. The first algorithm deals with sentences and is based on word scores. The second algorithm deals with single words and is based on phoneme scores. Both algorithms were evaluated with a corpus of typed answers based on three different Dutch speech materials. The percentage of differences between automatic and manual scoring was determined, in addition to the mean difference in speech recognition threshold. The sentence correction algorithm performed at a higher accuracy than commonly obtained with these speech materials. The word correction algorithm performed better than the human operator. Both algorithms can be used in practice and allow speech reception tests with open set speech materials over the internet.

AB Audiologic candidacy criteria for determining cochlear implantation candidacy in children are evolving. The objective of the study was to examine clinical practice related to the cochlear implantation of children who typically do not meet audiologic criteria for this technology. Practitioners' perspectives on the process and the factors influencing candidacy decisions were explored through focus group interviews with hospital and school-based practitioners. The interviews were analysed using qualitative techniques to identify key issues. The findings from the interviews informed a questionnaire which was sent to all cochlear implant centers in Canada to further examine clinician views and experiences with this special population. Responses were collected from 11 of the 12 centers and indicated that children with hearing outside typical criteria were receiving implants. The definition of 'borderline' varied across the programs from approximately 70 dB HL to less than 90 dB HL. All centers emphasized the importance of considering factors beyond the child's audiometric thresholds in candidacy decision-making.

AB Early diagnosis and intervention of hearing loss are directly influenced by the knowledge and attitude towards this condition among medical personnel, particularly in countries where screening is not performed routinely. The objective of this paper was to evaluate the attitude and knowledge of hearing loss in a group of physicians. A questionnaire with five Likert-type items and five multiple choice and fill-in-the-blank items was completed by 2727 physicians selected to start a medical residency. Results suggested that physicians' knowledge level on the matter is deficient and their attitude is far from the ideal; however, physicians selected for a residency in audiology showed slightly better results.

AB The objective of this study was to investigate whether universal neonatal hearing screening could be integrated in the youth health care program. The screening was performed by nurses of the well baby clinics. A three stage transient evoked otoacoustic emission screening was performed in three different screening settings in order to study the most effective set up regarding participation, refer rates, and costs. In one setting parents visited the well baby clinic, and in two settings babies were screened at home (either in combination with the screening for metabolic diseases or during an intake visit). Screening was performed on 3114 healthy newborns. The setting where universal neonatal hearing screening is integrated with the screening for metabolic diseases, proved to be most efficient and effective. The participation rate of 88.9% was highest in this setting and the overall refer rate (1.4%) was the lowest. The implementation of universal neonatal hearing screening by the well baby clinic nurses was judged to be possible. The results of this study formed the basis for nationwide implementation.

AB This paper provides an analysis of participation in paid employment for people with a hearing loss over the full span of adult ages. The paper is based on original analysis of the 2003 Australian survey of disability, aging and carers (SDAC). This analysis shows that hearing loss was associated with an increased rate of non-participation in employment of between 11.3% and 16.6%. Advancing age and the existence of co-morbidities contribute significantly to reduced participation in employment. A disproportionate impact is evident for women and for those having low education and communication difficulties. Controlling for co-morbidities, hearing loss was associated with a 2.1% increase of non-participation in employment, a proportional difference of 1.4 times the population. People with hearing loss were less likely to be found in highly skilled jobs and were over-represented among low income earners. The SDAC data set provides self-report findings on the experience of disability rather than hearing impairment. As such, these findings serve as a conservative estimate of the impact of hearing loss on accessing well-paid employment.

AB The hearing status of 109 Indigenous prisoners was investigated at five prison locations in Victoria, using audiological methods and face-to-face interview. The study found predominantly mild, sensorineural hearing loss. The rate of conductive hearing impairment was consistent with an age-matched general adult population (UK). All eardrums were intact, and 89% of middle-ears were normally air filled. Results showed 12% of prisoners had a hearing loss (average. 0.5, 1, 2, 4 kHz 25 dB) in at least one ear, compared with 5% in an age-matched Australian adult population. More than a third (36%) had high-frequency, sensorineural hearing impairment (4 or 6 kHz 25 dB), in one or both ears. Over half of the inmates (58%) reported hearing problems sometimes, and 4% reported a lot of hearing trouble. The majority of prisoners (92%) reported exposures to loud noise, and tinnitus was reported by 72% of prisoners. For hearing-impaired individuals within the correctional system, the reduced ability to communicate with ease may impact detrimentally on daily interactions, and may impede progress through rehabilitation programs.

AB South Africa has an exceptionally high incidence of traumatic brain injury in its paediatric population but very little systematic research has been conducted on the outcome of such injury. A number of socio demographic variables influence the mechanism of injury as well as its management. This paper reports on a study documenting the educational and audiological outcomes of a group of 100 subjects who sustained their injuries prior to the age of 12 years. The hearing and communication profile of this group is considered in relation to educational outcome. An illustrative case study will demonstrate the multiple influences on outcome in this setting, as well as the need for integrated team management. In the sample, 31% had a reported hearing loss, confirmed audiologically in 14% of subjects. The majority of the sample returned to a mainstream school. However, analysis indicated that about 75% of the sample was in need of specialized education, while only 22% of that sample had received any additional support. The implications of these findings for audiological policy and practice are highlighted.

AB The purpose of this paper was to present estimates of costs and effects of selected interventions for hearing impairment in Africa and Asia. The method used mathematical simulation models on the basis of WHO burden of disease information, and WHO-CHOICE costing databases. Findings showed that in both regions, screening strategies for hearing impairment and delivery of hearing aids cost between I$1000 and I$1600 per DALY, with passive screening being the most efficient intervention. Active screening at schools and in the community are somewhat less cost-effective. In the treatment of chronic otitis media, aural toilet in combination with topical antibiotics costs is more efficient than aural toilet alone, and costs between I$11 and I$59 in both regions. The treatment of meningitis with ceftriaxone costs between I$55 and I$217 at low coverage levels, in both regions. In more absolute terms, the vast majority of all considered intervention strategies are cost-effective strategies according to international benchmarks, in both regions concerned. In conclusion, various strategies are economically attractiv;e to reduce the disease burden of hearing impairment around the world.

AB Recent evidence suggests that sensitivity to the temporal fine structure (TFS) of sounds is adversely affected by cochlear hearing loss. This may partly explain the difficulties experienced by people with cochlear hearing loss in understanding speech when background sounds, especially fluctuating backgrounds, are present. We describe a test for assessing sensitivity to TFS. The test can be run using any PC with a sound card. The test involves discrimination of a harmonic complex tone (H), with a fundamental frequency F0, from a tone in which all harmonics are shifted upwards by the same amount in Hertz, resulting in an inharmonic tone (I). The phases of the components are selected randomly for every stimulus. Both tones have an envelope repetition rate equal to F0, but the tones differ in their TFS. To prevent discrimination based on spectral cues, all tones are passed through a fixed bandpass filter, usually centred at 11F0. A background noise is used to mask combination tones. The results show that, for normal-hearing subjects, learning effects are small, and the effect of the level of testing is also small. The test provides a simple, quick, and robust way to measure sensitivity to TFS.

AB This study examined: (1) the prevalence of hearing-aid use in a clinical population of adults with unilateral cochlear implants, (2) the relationship between hearing-aid use, severity of hearing loss, duration of deafness and duration of cochlear implant use, and (3) the benefits of bimodal hearing from the users' perspective. Using a retrospective design, 31 adults were identified as bimodal users, and 93 adults implanted in the same period were identified as non hearing-aid users. The two groups were similar in regards to duration of deafness but differed in severity of hearing loss and time since implantation. Questionnaires examining frequency and situations of hearing-aid use were completed by 24 of 31 bimodal users. Fifteen of these 24 adults reported hearing-aid use more than 50% of the time. These findings suggest that, of the 72 adults in this study with useable hearing (pure-tone average better than 110 dB), about 30% or less regularly combined a hearing aid and cochlear implant. The questionnaire results suggest that regular bimodal users prefer bimodal hearing across a variety of listening environments such as music, noise, and reverberation.

AB The purpose of this study was to investigate the efficiency of the Swiss hearing aid dispensing system, and to determine factors contributing to successful hearing aid provision. A national cross sectional survey was performed using a postal questionnaire with 8707 adult hearing aid owners (response rate 62%). To correct results for a potential non-response bias, 193 randomly selected non-respondents were contacted by telephone. Data on hearing loss and type of hearing aid were provided by the hearing aid dispensing practice. Logistic regression analyses were performed to identify determinants of non-regular use and dissatisfaction. Eighty-five percent used their device(s) regularly, 12% only occasionally and 3% never. Eighty percent were satisfied with their aids. Non-regular use of hearing aids was significantly associated with age, gender, regional language, total duration of use, type of amplification, hearing aid category, hearing loss, and dissatisfaction with and difficulties in managing the aid. Dissatisfaction was associated with regional language, total duration of use, difficulties in managing the aid, and non-regular use. It was concluded that rates of regular hearing aid use and satisfaction are high in Switzerland.

DE FM system; Cochlear implant; Speech recognition
ID HEARING HANDICAP INVENTORY; NOISE; USERS
AB The primary aim of this study was to examine the effects of frequency-modulated (FM) settings on speech-recognition performance in noise of listeners using two different cochlear implant speech processors. Participants included eight users of ESPrit 3G speech processors and nine users of Auria speech processors. A modified adaptive-testing paradigm was used to assess speech recognition in noise with the cochlear implant and FM system at four receiver-gain settings: +6, +10, +14, or +20. In the no-FM condition, performance differences were not detected between the two processor groups. In the FM conditions, significantly better performance was found for participants with the Auria processor compared to those using the ESPrit 3G processor. Increases in receiver gain did not significantly improve speech recognition of participants using ESPrit 3G processors, but did significantly influence performance for those using Auria processors. For Auria users, the +6 setting resulted in significantly poorer performance than all other conditions, and optimal FM performance was found in the +14 and +20 gain settings. Clinical recommendations will be provided according to results of the study.

AB Routine recall for reassessment of adult hearing-aid users has been recommended by national audiology standards in the United Kingdom. The objective of this study was to determine whether recalling patients after three years was appropriate within a publicly-funded health service model, by investigating changes in hearing thresholds, and problems presented by adult hearing-aid users at reassessment appointments. Patients who had not had contact (except for the repair service) with the department for three years or more were invited to participate in the pilot reassessment programme, and 62% attended (total of 95 subjects). The reassessment appointment was found to be clearly appropriate for 58% of subjects seen, using our defined criteria. 100% of subjects were also found to need minor interventions. It is suggested that recall for reassessment after three years was generally appropriate for this patient group whose needs were not adequately met by self-referral and repair services. Some evidence was also found that subjects who have not accessed open repair clinics might be suitable for targeting for reassessment appointments.

AB Cochlear implants usually employ an automatic gain control (AGC) system as a first stage of processing. AGC1 was a fast-acting (syllabic) compressor. AGC2 was a dual-time-constant system; it usually performed as a slow-acting compressor, but incorporated an additional fast-acting system to provide protection from sudden increases in sound level. Six experienced cochlear-implant users were tested in a counterbalanced order, receiving one-month of experience with a given AGC type before switching to the other type. Performance was evaluated shortly after provision of a given AGC type and after one-month of experience with that AGC type. Questionnaires, mainly relating to listening in quiet situations, did not reveal significant differences between the two AGC types. However, fixed-level and roving-level tests of sentence identification in noise both revealed significantly better performance for AGC2. It is suggested that the poorer performance for AGC1 occurred because AGC1 introduced cross-modulation between the target speech and background noise, which made perceptual separation of the target and background more difficult.

AB The aim of this study was to describe the prevalence of specific audiogram configurations in a healthy, otologically screened population between 55 and 65 years old. The audiograms of 1147 subjects (549 males and 598 females between 55 and 65 years old) were collected through population registries and classified according to the configuration of hearing loss. Gender and noise/solvent-exposure effects on the prevalence of the different audiogram shapes were determined statistically. In our population 'Flat' audiograms were most dominantly represented (37%) followed by 'High frequency Gently sloping' audiograms (35%) and 'High frequency Steeply sloping' audiograms (27%). 'Low frequency Ascending' audiograms, 'Mid frequency U-shape' audiograms and 'Mid frequency Reverse U-shape' audiograms were very rare (together less than 1%). The 'Flat'-configuration was significantly more common in females, whereas the 'High frequency Steeply sloping'-configuration was more common in males. Exposure to noise and/or solvents did not change this finding. In addition, females with a 'Flat' audiogram had a significantly larger amount of overall hearing loss compared to males. Furthermore, our data reveal a significant association between the prevalence of 'High frequency Steeply sloping' audiograms and the degree of noise/solvent exposure, despite a relatively high proportion of non-exposed subjects showing a 'High frequency Steeply sloping' audiogram as well.

AB This study explores the opportunities for and barriers to improving environmental conditions in order to reduce the risk for music-induced hearing loss in people who attend music venues. Individual semi-structured interviews were held with 20 representatives of music venues and of governmental organizations, according to a semi-structured interview guide. The interviews were audiotaped, transcribed, and systematically coded using a content-analysis technique. Reported opportunities to reduce music volume included improving the acoustics and installing advanced speaker systems. The most important barrier reported was the lack of clear definitions of what levels of high-volume music are hazardous. Other barriers mentioned included economic considerations, and the beliefs that visitors demand high-volume music in music venues and are personally responsible for their own hearing. Before measures to improve environmental conditions are implemented, the exact dangers of exposure to high-volume music have to be established. Evidence-based guidelines and safety standards for leisure-time noise exposure should therefore be developed.

AB The purpose of the present study was to investigate possible associations between college students' attitudes, risk-taking behaviour related to noisy activities, and hearing problems such as threshold shifts or self-experienced hearing symptoms. The sample included 258 students aged between 17 and 21 enrolled at the University of Pennsylvania, USA. A questionnaire measuring attitudes towards noise, use of hearing protection, and self- reported hearing symptoms was distributed among the students. After completing the questionnaire a hearing screening, including pure-tone audiometry and tympanometry, was conducted. The result revealed that 26% had thresholds poorer than the screening level of 20 dBHL. Attitudes were significantly related to self-experienced hearing symptoms, but not to threshold shifts. Attitudes and noise sensitivity was, significantly related to use of hearing protection. Hearing protection use was found in activities such as using firearms, mowing lawns, and when using noisy tools but was less reported for concerts and discotheques. It can be concluded that the young adults in this study expose themselves to hearing risks, since the use of hearing protection is in general very low.

AB The 'fast' method for measuring psychophysical tuning curves (PTC) uses a masker that sweeps across frequency and a Bekesy threshold tracking procedure. The fast-PTC procedure has been recommended as a technique for diagnosing cochlear dead regions in adults. The aim of this study was to evaluate the fast-PTC procedure in children. Twelve normal-hearing children (7-10 years old) and five adults were tested. The fast-PTCs were measured for 1000 and 4000 Hz signals using ascending and descending masker sweeps. Measurements were repeated on a separate day to assess test-retest variability. All children were able to perform the task; however it was possible to define the tip in only 87% of the fast-PTCs. Although the variability in tip frequency was higher for children, the mean difference between children and adults was not statistically significant. As expected, the difference on retest was higher for children. Studies investigating the use of the fast-PTC procedure with hearing-impaired children are warranted.

AB The aims of this study were to investigate statistically the way a revised version of the children's implant profile (GOSHChIP) is used to inform candidacy decisions and explore its utility in predicting outcomes in the first three years of implant use. A retrospective case series analysis design was employed. Data were collated for 127 children with a mean age of 4.7 years at implantation. Concerns in a number of areas of the child's pre-implant functioning as rated on the GOSHChIP (spoken or manual communication skills, cognitive abilities, family structure and support, and use of hearing aids) were associated with speech perception and intelligibility outcomes following implantation. In terms of non-verbal cognitive abilities, the score on tests of fluid reasoning skills (sequencing), that contributes to the cognitive factor on the GOSHChIP, was found to significantly predict speech perception and speech intelligibility post implant. The GOSHChIP is a useful tool in making paediatric cochlear implant candidacy decisions, and in forming a guide for counselling parents about the potential benefit their child may receive from an implant.

ID CODING STRATEGY; SYSTEM
AB The objective of this study was to explore cochlear implant users' speech perception performance in quiet and in noise for low to moderate stimulation rates. Eight postlingually deaf adult users of the Nucleus CI24 cochlear implant (contour electrode array) using the ESPrit 3G speech processor participated in this study. Monosyllabic word recognition in quiet and sentence perception in noise was evaluated for low to moderate stimulation rates of 275, 350, 500, and 900 pulses-per-second/channel (pps/ch). All four stimulation rate programs were balanced for loudness. A repeated ABCD experimental design was employed. Take home practice was provided with each stimulation rate. Subjects also responded to a comparative questionnaire to examine their rate preference for a variety of listening situations. Results for six of the eight subjects showed no significant effect of rate for monosyllables in quiet. However, results for the sentence test in noise demonstrated improvements with 500 or 900 pps/ch stimulation rates in seven out of the eight subjects. Although there was not a close relationship between each subject's subjective preference and the rate program that provided best speech perception, most subjects indicated a preference for 500 pps/ch rate in noise.

AB The objective of this study was to determine the psychometric properties of a Chinese (Cantonese) version of the Tinnitus Questionnaire (TQ), which is a psychometric self-report measure of perceived tinnitus-related distress. The subjects were 114 adults who attended audiology clinics with a primary or secondary complaint of tinnitus. They completed the Chinese versions of the TQ (TQ-CH), Short-Form 36 Health Survey (SF-36), and Hospital Anxiety and Depression Scale (HADS). The subjective severity of tinnitus and tinnitus-related problems were scored using rating scales. The TQ-CH and its subscales had good internal consistency reliability estimates (alpha = 0.75-0.94), which were comparable to those of the original version. Significant correlations were observed between the TQ-CH and psychological distress, tinnitus-related problem ratings, and severity ratings. Factor analysis showed the high construct validity of the TQ-CH subscales. High test-retest reliablity (intraclass correlation coefficient =0.96) was observed. The results suggest that the TQ-CH is a reliable and valid measure of general tinnitus-related distress that can be used in clinical settings to quantify the impact of tinnitus on daily living.

AB Distortion product otoacoustic emissions (DPOAEs) have been used to examine the development of hearing in the rat and gerbil. However, no reports of DPOAE measurement from the onset of hearing in mice are available. Commercially-available components were assembled and adapted to provide a suitable probe microphone and sound delivery system for measuring DPOAE in developing C57BL/6J mice. Furthermore, DPOAE data were compared with the findings of the auditory brainstem response (ABR). DPOAEs were obtained at 8 kHz from 11 days after birth, 20 kHz from 12 days, and 30 kHz from 13 days. Adult-like patterns of DPOAE were obtained 21 days at 8 and 20 kHz, and 28 days at 30 kHz. On the other hand, the ABR thresholds at 12 to 36 kHz appeared between 11 and 12 days and were saturated at 14 days. Based on these data, the onset of measureable DPOAEs in the mouse were earlier than in the rat and gerbil. The maturation of DPOAE in the mouse begins at a lower frequency in the high frequency range. In addition, the ABR threshold reached maturation earlier than DPOAE.

AB This paper describes low-frequency auditory steady-state responses (ASSRs) to speech-weighted noise stimuli. The effect of modulation frequency was evaluated within the frequency range below 40 Hz. Furthermore, objective ASSR measures were related to speech understanding performance in normal-hearing and hearing-impaired listeners. The variability in ASSR recordings over independent test sessions was larger between subjects than within. Trends of increased responses around 10 and/or 20 Hz were found in all subjects. Obtained latency estimates of the responses pointed to primarily cortical sources involved in ASSR generation at low frequencies. Furthermore, significant differences between normal-hearing and hearing-impaired adults were found for ASSRs to stimuli related to the temporal envelope of speech. Comparing these responses with phoneme identification scores over different stimulus levels showed both measures increased with stimulus level in a similar way (rho = 0.82). At a fixed stimulus level, ASSRs were significantly correlated with speech reception thresholds for phonemes and sentences in noise (rho from -0.45 to -0.53). These results indicate that objective low-frequency ASSRs are related to behavioral speech understanding, independently of level.

AB This study aimed to assess the extent and implications of short-term hearing fluctuation in Meniere's disease. Thirty-six subjects diagnosed with Meniere's were recruited to measure their own hearing using in-situ audiometry via a hearing aid (Widex Diva) and a portable programmer (SP3). Self-hearing tests measuring up to 14 frequency bands were conducted three times a day over eight weeks using the expanded Sensogram (TM). Twenty-three ears showed low frequency fluctuation while ten fluctuated in mid frequencies with some 'double peak' audiogram configurations. Eight ears in the later stages of Meniere's, contrary to expected, also recorded fluctuation across all frequencies. Self-hearing testing Meniere's ears over eight weeks revealed great hearing fluctuation with significant changes in audiogram configuration. It suggests that as endolymphatic hydrops progresses through the cochlea, low frequency fluctuation is followed by fluctuation in the mid frequencies, leading to fluctuation across all frequencies. Use of a self-hearing test may facilitate diagnosis and hearing aid fitting for this population, as clinical audiograms may not provide accurate information of hearing fluctuation.

AB The effects of hearing impairment on the person with the impairment and on their significant others are pervasive and affect the quality of life for all involved. The effect of hearing impairment on significant others is known as a third-party disability. This study aimed to develop and psychometrically test a scale to measure the third-party disability experienced by spouses of older people with hearing impairment. The Significant Other Scale for Hearing Disability (SOS-HEAR) was based on results of a previous qualitative study investigating the effect of hearing impairment on a spouse's everyday life. Psychometric testing with 100 spouses was conducted using item analysis, Cronbach's alpha, factor analysis, and test-retest reliability. Principal components analysis identified six key underlying factors. A combined set of 27 items was found to be reliable (alpha =0.94), with weighted kappa for items ranging from fair to very good. The SOS-HEAR is a brief, easy to administer instrument that has evidence of reliability and validity. The SOS-HEAR could serve as a means of identifying spouses of older people with hearing impairment in need of intervention, directed towards either the couple or the spouse alone.

AB The main aim of the study is to address the relationship between hearing status and need for recovery. In addition, the role of hearing status in the relationship between psychosocial work characteristics (i.e. job demands and job control) and need for recovery was assessed. The sample comprised 925 normally-hearing and hearing-impaired working adults (aged 18-65 years) participating in the National Longitudinal Study on Hearing. Hearing status was determined using the national hearing (speechin-noise) test over the internet. Psychosocial work characteristics and need for recovery were assessed using the job content questionnaire and the Dutch questionnaire on the experience and assessment of work. Regression models revealed a significant association between hearing status and need for recovery after work, poorer hearing leading to an increasing need for recovery. Additionally, poorer hearing led to a higher odds for risky levels of need for recovery. Hearing status did not influence the significant relationship between psychosocial work characteristics (i.e. job demand and job control) and need for recovery after work. Implications for clinical practice, such as the necessity of having adequate enablement programs for this specific group of patients, are discussed.

AB The objective of this study was to examine behaviors and attitudes of Brazilian teenagers towards noise, and determine their audiological characteristics. Participants were 245 young persons (14 to 18 years old) who attended private school. Behaviors and attitudes were measured using the validated Portuguese version of the Youth Attitude to Noise Scale (YANS). Pure-tone audiometry was used to evaluate the hearing of a sub-sample of 24 participants. Music played through personal media players was the most common exposure reported. A substantial percentage of participants reported temporary tinnitus (69%) after attending discos, music concerts, and listening to music through headphones. Tinnitus complaints were more frequent among females (41%) than males (27%). Four participants (1.6%) reported use of a hearing protector. Among a sub-sample of 24 participants, two (8%) young women had bilateral audiometric notches. YANS scores in the present study were slightly lower than those obtained in Sweden and the US, indicating a more negative attitude towards noise. Gender, age, country, and/or region are variables that will influence exposure to noise or music and possibly hearing outcomes.

AB Individuals with auditory neuropathy (AN) often suffer from temporal processing deficits causing speech perception difficulties. In the present study an envelope enhancement scheme that incorporated envelope expansion was used to reduce the effects of temporal deficits. The study involved two experiments. In the first experiment, to simulate the effects of reduced temporal resolution, temporally smeared speech stimuli were presented to listeners with normal hearing. The results revealed that temporal smearing of the speech signal reduced identification scores. With the envelope enhancement of the speech signal prior to being temporally smeared, identification scores improved significantly compared to temporally smeared condition. The second experiment assessed speech perception in twelve individuals with AN, using unprocessed and envelope-enhanced speech signals. The results revealed improvement in speech identification scores for the majority of individuals with AN when the envelope of the speech signal was enhanced. However, envelope enhancement was not able to improve speech identification scores for individuals with AN who had very poor unprocessed speech scores. Overall, the results of the present study suggest that applying envelope enhancement strategies in hearing aids might provide some benefits to many individuals with AN.

AB Few materials are available to assess speech perceptual skills in young children without hearing impairments. However, children with a range of developmental conditions are at risk of speech discrimination deficits. Tasks that reliably assess speech perception skills are thus necessary for research and clinical practice. The development and application of two speech perception tests are described. Data were collected from 105 children, aged 4-5 years, attending mainstream schools, on two tasks, mispronunciation detection and non-word XAB, in quiet and in a background of multi-talker babble. Children's receptive language skills were also measured. Performance on mispronunciation detection was significantly better than on the XAB non-word task, and significantly better in quiet than in babble. Performance significantly improved with age, and speech discrimination was significantly related to receptive language abilities. Scores obtained in quiet and in babble were highly correlated and findings suggest there may be no advantage to testing in noise, except to avoid ceiling effects on performance. These tasks prove useful in the assessment of young children who may have speech discrimination deficits.

AB The objective of this research was to create a Mandarin closed-set sentence recognition test based on the English pediatric speech intelligibility (PSI) test (Jerger & Jerger, 1984) for evaluation of speech perception in children as young as three years of age. Developmentally normal children (N = 93), 3-6 years of age, were administered the Mandarin PSI (MPSI) via a computer-controlled protocol. Perfect performance was observed for all children in quiet and at +10 and +5 dB signal-to-noise ratios (SNRs). Significant age and developmental trends were seen for the more difficult SNRs, 0 dB, -5 dB, and -10 dB, with 75% of 5-6 year olds reaching the most difficult SNR. Children who reached each of the more difficult SNRs, regardless of age, exhibited the same pattern of performance on all easier conditions, indicating that the final SNR achieved, rather than percent correct scores, may be a better descriptor of performance. The MPSI comprises part of a hierarchical assessment battery for pediatric speech perception for evaluation of intervention alternatives for Mandarin-speaking children with hearing impairment.

AB A Danish speech intelligibility test for assessing the speech recognition threshold in noise (SRTN) has been developed. The test consists of 180 sentences distributed in 18 phonetically balanced lists. The sentences are based on an open word-set and represent everyday language. The sentences were equalized with respect to intelligibility to ensure uniform SRTN assessments with all lists. In contrast to several previously developed tests such as the hearing in noise test (HINT) where the equalization is based on scored (objective) measures of word intelligibility, the present test used an equalization method based on subjective assessments of the sentences. The new equalization method is shown to create lists with less variance between the SRTNs than the traditional method. The number of sentence levels included in the SRTN calculation was also evaluated and differs from previous tests. The test was verified with 14 normal-hearing listeners; the overall SRTN lies at a signal-to-noise ratio of -3.15 dB with a standard deviation of 1.0 dB. The list-SRTNs deviate less than 0.5 dB from the overall mean.

AB To study the spatial hearing abilities of bilateral hearingaid users in multi-talker situations, 20 subjects received fittings configured to preserve acoustic cues salient for spatial hearing. Following acclimatization, speech reception thresholds (SRTs) were measured for three competing talkers that were either co-located or spatially separated along the front-back or leftright dimension. In addition, the subjects' working memory and attentional abilities were measured. Left-right SRTs varied over more than 14 dB, while front-back SRTs varied over more than 8 dB. Furthermore, significant correlations were observed between left-right SRTs, age, and low-frequency hearing loss, and also between front-back SRTs, age, and high-frequency aided thresholds. Concerning cognitive effects, leftright performance was most strongly related to attentional abilities, while front-back performance showed a relation to working memory abilities. Altogether, these results suggest that, due to raised hearing thresholds and aging, hearingaid users have reduced access to interaural and monaural spatial cues as well as a diminished ability to 'enhance' a target signal by means of top-down processing. These deficits, in turn, lead to impaired functioning in complex listening environments.

DE Speech perception; Cochlear implant; Behavioral measures

AB This study was undertaken to assess the speech perception benefits, 24 months after cochlear implantation (CI), in 20 young people (age at CI, 8-18.5 years) with prelingual profound hearing loss, in addition to the use of a proposed CI candidacy assessment profile. Speech perception was evaluated in terms of word and sentence perception before CI, and at six-monthly intervals for two years after CI. Before undergoing CI, all participants were tested on a pre-implantation assessment profile. Compared to the pre-CI findings, group results over 24 months post-CI demonstrated improved speech perception abilities reaching, on average, 46% for word recognition, 71.3% for sentences in quiet, and 33.6% for sentences in noise. Pre-CI profile scores correlated significantly with all speech perception results obtained 24 months after CI. Thus, despite their relatively late ages at implantation, all participants showed gradually improving performance in speech perception. The results showed a high variability in the outcomes of the participants. The pre-CI profile appeared to be useful in formulating realistic expectations of CI outcome during pre-implantation consultations, suggesting that expectations can and should be managed according to each patient's pre-implantation assessment.

ID RECREATIONAL NOISE EXPOSURE; HEARING; ADOLESCENTS; MUSIC; PLAYERS
AB Long term use of personal stereo players (PSP) is now established as a potential risk to hearing health if exposure levels are not maintained at what are accepted as safe levels. Comparison of PSP user test results indicate that mean listening levels (L(Aeq)) have decreased from 86.1 dB in 2002/03 to 81.3 dB in 2008 and mean exposure levels (L(Aeq,8h)) have decreased from 79.8 dB to 74.7 dB over the same time period, in a user population whose mean age has increased from 23.6 years (SD = 5.7) to 26.0 years (SD = 10.5). This reduction in exposure level of 5 dB also means that the percentage of user population at risk of noise injury and subsequent hearing loss has decreased from 25% to 17% when judged by criterion commonly used for workplace occupational noise exposure standards.

AB Frequency-dependent microphone directionality alters the spectral shape of sound as a function of arrival azimuth. The influence of this on horizontal-plane localization performance was investigated. Using a 360 loudspeaker array and five stimuli with different spectral characteristics, localization performance was measured on 21 hearing-impaired listeners when wearing no hearing aids and aided with no directionality, partial (from 1 and 2 kHz) directionality, and full directionality. The test schemes were also evaluated in everyday life. Without hearing aids, localization accuracy was significantly poorer than normative data. Due to inaudibility of high-frequency energy, front/back reversals were prominent. Front/back reversals remained prominent when aided with omnidirectional microphones. For stimuli with low-frequency emphasis, directionality had no further effect on localization. For stimuli with sufficient mid- and high-frequency information, full directionality had a small positive effect on front/back localization but a negative effect on left/right localization. Partial directionality further improved front/back localization and had no significant effect on left/right localization. The field test revealed no significant effects. The alternative spectral cues provided by frequency-dependent directionality improve front/back localization in hearing-aid users.

Animals were exposed to noise (6 kHz, at 120 dB SPL for 60 minutes) and then auditory brainstem responses (ABR) and vestibulo-ocular reflex (VOR) were measured at 6 hours, 1 day, 3, 7, and 21 days after noise. Western blotting and immunostaining for 4-hydroxy-2-noneal (4-HNE) and vascular endothelial growth factor (VEGF) were performed in the cochlear and vestibular regions at 1 and 7 days after noise exposure. A significant decrease of VOR gain was observed on day 1 and the recovery was completed at day 21. ABR threshold values reached a level of 80 dB at day 1 after trauma reaching a value of about 50 dB SPL on day 21. 4-HNE expression, a marker of lipid peroxidation was strongly increased in the cochlea. In the vestibule, 4-HNE immunoreactivity was faint. However, VEGF was up-regulated both in the cochlea and vestibule. In conclusion, the expression of VEGF in both cochlear and vestibular structures suggests a reparative role with potentially therapeutic implications.

AB ECochG has long been shown to complement the diagnosis of MD, primarily through measurement of the SP/AP amplitude ratio. While reported in the literature to be highly specific to this disorder, ECochG's sensitivity in the general MD population remains relatively low (ranging from 20-65%). The current study assessed the sensitivity and specificity of the ECochG protocol we employ for suspected MD patients, which includes measuring both the amplitudes and areas of the SP and AP to clicks (to derive the SP/AP amplitude and area ratios), and the SP amplitudes to 1000 and 2000 Hz tone bursts. A retrospective chart review was conducted to compare ECochG results from 178 suspected MD patients with their eventual diagnoses. Measurements of highest sensitivity and specificity (determined using a logistic regression analysis) included: SP amplitude, SP area, SP/AP area ratio, and total SP-AP area. Sensitivity and specificity values associated with these measures were 92% and 84%, respectively. The sensitivity value is considerably higher than previously reported, and is attributable to the inclusion of area measurements in our protocol.

AB The widespread use of portable listening devices (PLDs) has increased concern about the potential for hearing impairment caused by their use. The current study investigated the effects of external noise and exercise on the use of PLDs. The 24 participants listened to the same song on an iPod during rest-in-quiet, rest-in-noise, and exercise-in-noise conditions. Preferred listening levels (PLLs) were recorded and participants' maximum noise doses were calculated. Participants selected significantly higher listening levels in both noise conditions than in the quiet condition. The variability of volume selection was reduced significantly in the noise conditions. The maximum daily noise dose would have been exceeded by seven participants in the rest-in-noise condition and by eight in the exercise-in-noise condition compared to one participant in the rest-in-quiet condition. These results indicated that increased background noise causes individuals to increase the volume on their PLDs to potentially dangerous levels and that increased noise alone was not the only factor affecting the participants as the addition of exercise induced even further increases in PLLs.

AB The detection of adult cortical auditory evoked potentials (CAEPs) can be challenging when the stimulus is just audible. The effectiveness of a statistic compared with expert examiners in (1) detecting the presence of CAEPs when stimuli were present, and (2) reporting the absence of CAEPs when no stimuli were present, was investigated. CAEPs recorded from ten adults, using two speech-based stimuli, five stimulus presentation levels, and non-stimulus conditions, were given to four experienced examiners who were asked to determine if responses to auditory stimulation could be observed, and their degree of certainty in making their decision. These recordings were also converted to multiple dependent variables and Hotelling's T2 was applied to calculate the probability that the mean value of any linear combination of these variables was significantly different from zero. Results showed that Hotelling's T2 was equally sensitive to the best of individual experienced examiners in differentiating a CAEP from random noise. It is reasonable to assume that the difference in response detection for a novice examiner and Hotelling's T2 would be even greater.

AB FM systems have been used to compensate for poor signal-to-noise ratios in classrooms. This study evaluates benefits of a 6-week trial of personal FM systems used during the school day for children with reading delay aged 6-11 years, using a randomized control design. Teachers and children completed the LIFE-UK questionnaire. Test-retest reliability of the LIFE-UK children's version was confirmed in a separate group of 18 children from the same school. The 23 children in the FM group had significantly improved teacher ratings, and the children's ratings of classroom listening for difficult situations were significantly better after the trial. These changes did not occur for the 23 control-group children. Most children (92%) commented positively about the FM after the trial. It is likely that a longer FM trial or a specific reading intervention combined with FM will be required for the benefits of enhanced listening to affect performance on standardized reading tests.

AB The effects of four configurations of an environmental noise reduction (ENR) algorithm on preferences, speech understanding, and satisfaction were investigated. The gain reduction at 0 dB modulation depth was either 10 dB in all channels (ENR StrongFlat) or shaped from 2-10 dB across channels according to a speech importance function (ENR MildSII). This gain reduction was either invariant (ENR Constant) or varied with (ENR Variable) the noise level. Ten hearing-impaired participants blindly compared pairs of configurations in real-world situations and recorded their preferences. Sentence reception thresholds (SRTs) were measured in quiet and noise, and satisfaction was rated with speech in noise. Half of the participants preferred ENR MildSII and half preferred ENR StrongFlat. All preferred ENR Variable to ENR Constant. Overall, the preferred ENR configuration was preferred to ENR off in 90% of responses. No statistically significant effect on SRTs was found, but a clinically significant effect of up to 2 dB could not be ruled out from the available data. ENR significantly improved satisfaction for listening comfort, ease of speech understanding, and sound quality.

AB An n-of-m speech coding strategy has been developed for the Clarion Cochlear Implant Series 1.x (1.0 & 1.2). The basic principle is to reduce the number of stimuli per cycle, by neglecting the less significant spectral components, and to concentrate on the more dominant frequency bands. In this study 20 subjects, implanted with a Clarion device, used an n-of-m strategy at 1666 pps per channel. The outcomes using this strategy were compared with the outcomes using conventional processing (CIS at 833 pps/channel). Eight of the 20 subjects underwent additional testing with the n-of-m strategy with the rate set at 833 pps/channel. Using the n-of-m strategy at 1666 pps showed statistically significant improvement in performance over the CIS strategy, with 16 of the 20 subjects achieving better results. However, there was no statistically meaningful difference in performance between n-of-m at 833 pps and the CIS strategy running at the same rate. Results therefore suggest that n-of-m strategy can be an alternative to CIS, particularly when the implant hardware limits the overall stimulation rate.

AB In order to evaluate the efficiency of middle-ear prostheses in near-real conditions, an artificial model was developed that approximately simulates the actual geometrical and biomechanical properties of the ear system (excluding the ossicular chain). The sound transmission characteristics of selected commercial middle-ear prostheses and of a synthetic test material were measured using laser Doppler vibrometry (LDV) in this model. The model's realistic properties enabled clinical tympanometry to be used to control the stiffness. In addition the influences of the implant mass on transmission characteristics were investigated. With an averaged displacement between 10 and 100 nm/Pa up to 2000 Hz, the transmission characteristic of the model was comparable with data obtained from the intact middle ear in temporal bone experiments. From the acoustical point of view, no significant material-specific differences could be found. Increasing the mass of the implants to more than 50 mg results in poorer acoustic transmission. In general, changes to the stiffness involving compliance values greater than 3.5 ml and smaller than 0.2 ml led to poorer acoustic transmission.

AB This paper deals with the question of how the general public should be addressed when offering hearing screening. Postal-based questionnaires in the United Kingdom, Germany, and the Netherlands were sent to users of hearing devices, those that are in the process of obtaining one, or those that have indicated that they have special interest in hearing. Results of the survey indicated that respondents were enthusiastic about the idea of being able to carry out hearing self-screening tests via the internet, telephone, or questionnaires. A questionnaire as a method to screen on hearing was generally preferred above using the internet, which was preferred over using the telephone for the test. About 27% of the respondents indicated to use exclusively one method. Most respondents indicated that either method provided would be of interest (41%), 17% indicated not to be interested in conducting screening tests using the internet.

AB The aim of this study was to establish parameters for the gaps-in-noise test in normal-hearing young adults. One hundred subjects (50 males and 50 females) received an audiological evaluation to rule out hearing loss and auditory processing disorder. The gaps-in-noise test was then conducted on all subjects. The mean gap detection threshold was 4.19 ms. A psychometric function by gap duration was constructed, revealing that the percentage of correct responses was less than or equal to 5% for a gap duration of 2 ms, 10-30% for a gap duration of 3 ms, 60-70% for a gap duration of 4 ms, and over 96% for gap durations of 5 ms or longer. The results suggest that the data obtained can be applied as reference values for future testing. In the subjects evaluated, the gaps-in-noise test proved to be consistent with low variability.

AB All hearing aids and communication devices introduce nonlinear distortion. The perception of distortion by hearing-impaired subjects was studied using artificial controlled distortions of various amounts and types. Subjects were asked to rate the perceived quality of distorted speech and music. Stimuli were subjected to frequency-dependent amplification as prescribed by the 'Cambridge formula' before presentation via Sennheiser HD580 earphones. The pattern of the ratings was reasonably consistent across subjects, but two of the eight subjects showed inconsistent results for the speech stimuli. Center clipping and soft clipping had only small effects on the ratings, while hard clipping and 'full-range' distortion had large effects. The results indicate that most hearing-impaired subjects are able to make orderly and consistent ratings of degradations in sound quality introduced by nonlinear distortion. The pattern of results could be predicted reasonably well using a model developed to account for the perception of distortion by normally hearing subjects.

AB This Study investigated the change in music perception of adults undergoing cochlear implantation. Nine adults scheduled for a cochlear implant (CI) were assessed oil it music test battery both prior to implantation (whilst using hearing aids; HAs), and three months after activation of their CIs. The results were compared with data from it group of longer-term CI users and a group of HA-only users. The tests comprised assessments of rhythm, pitch, instrument, and melody perception. Pre-to-post surgery comparisons showed no significant difference in the rhythm, melody, and instrument identification scores. Subjects' scores were significantly lower post-implant for ranking pitch intervals of one octave and a quarter octave (p = 0.007, and p < 0.001, respectively), and were only at chance levels for the smaller interval. However, although pitch perception was generally poorer with a CI than with it HA, it is likely that the use of both devices simultaneously could have provided higher scores for these subjects. Analysis or the other tests' results provided insights into factors affecting music perception for adults with severe to profound hearing impairment.

AB This study evaluated the use of multiple auditory steady-state responses (ASSRs) to estimate the growth of loudness in listeners with normal hearing. Individual intensity functions were obtained from measures of loudness growth using the contour test and front the electrophysiological amplitude measures of multiple amplitude-modulated (77-105 Hz) tones (500, 1000, 2000, and 4000 Hz) simultaneously presented to both ears and recorded over the scalp. Slope analyses for the behavioural and electrophysiological intensity functions were separately performed. Response amplitudes of the ASSRs and loudness sensation judgements increase as the Stimulus intensity increases for the four frequencies studied. A significant relationship was obtained between loudness and the ASSRs. The results of this study Suggest that the amplitude of the ASSRs may be used to estimate loudness growth at least for individuals with normal hearing.

AB Anterior semicircular canal (ASC) lithiasis is uncommon and usually self-treated. In the rare cases when such patients seek medical advice, diagnosis requires careful consideration of the patient's symptoms and the clinical characteristics of the nystagmus triggered by the Dix-Hallpike (D-H) examination. In this study, two atypical cases of ASC benign paroxysmal positional vertigo (BPPV) are presented and the relevant literature is reviewed. Regardless of their unique symptoms, both participants in this study were diagnosed with lithiasis of the left ASC. The clinical manifestations of ASC BPPV may differ significantly from typical symptoms seen in the more common posterior semicircular canal BPPV The possible mechanisms responsible for this intriguing variance, as well as guidelines for diagnosing the affected side. are discussed.

AB Hearing-aid use in the elderly population is problematic since not all people who would benefit from hearing aids actually obtain one. In this study, the relationship between pre-fitting expectations and willingness to use hearing aids is addressed.
   One hundred adult hearing aid candidates (mean age 68.6 years) were randomly recruited from eight different private. ENT practices. The subjects completed a questionnaire comprising a number of different aspects of expectation and some additional variables potentially influencing willingness to use hearing aids. Based on the outcome of the questionnaire a linear regression model predicting motivation to use hearing aids was calculated and evaluated.
   Among the 11 parameters evaluated three contributed significantly to the model of willingness. The three predictor variables were expectations towards improvement of quality of life, stigmatization, and self-rated hearing ability. They accounted for about 55% of the variability in the data for willingness. Examination of a sub-sample three months after the survey had taken place revealed a distinct relationship between willingness and the decision to obtain or decline hearing aids. In conclusion, the results strongly encourage supporting positive expectations in order to motivate individuals with hearing impairment to use hearing systems.

Although research shows that industrial workers have a higher propensity to noise-induced hearing loss, musicians can also develop a hearing loss from noise exposure. Furthermore, musicians can suffer from tinnitus, hyperacusis, and distortion, among other hearing disorders, which can affect their work more severely than a hearing loss. This study investigated the use of hearing protectors, the prevalence of self-reported hearing disorders among musicians, and the importance of these hearing disorders to the musicians. The musicians at three Danish symphony orchestras were asked to complete a questionnaire on the topic. Results showed that Danish musicians are aware of the dangers of loud music, yet they rarely use hearing protectors and not always correctly; however, musicians with hearing disorders use hearing protectors more frequently. In addition, the musicians questioned suffered from different hearing disorders. Education is needed to change musicians' opinion of hearing conservation and hearing protectors. The education must be directed to both the musicians and the administration of the symphony orchestras.

AB Research suggests that Vestibular Rehabilitation (VR) is an effective treatment for dizziness, but there is currently no measure specifically designed to assess treatment outcome, A review of existing self-report measures of dizziness indicates that no measure has been designed for longitudinal application and all suffer from limitations which restrict their usefulness in measuring VR outcome. A need for a psychometrically robust patient-oriented measure of quality of life benefit from VR is identified. The aim of the present study was to explore dimensions relevant to VR with a view to developing a measure of outcome. Eighteen adults receiving VR participated in interviews about the quality of life impact of dizziness. Qualitative analysis revealed 64 themes describing self-perceived quality of life impact. Themes were developed into potential questionnaire items and 35 were selected to represent the quality of life impact of dizziness in a prototype questionnaire. A quarter of items in the prototype questionnaire refer to issues not addressed by existing measures; the remaining items draw together issues covered by the range of questionnaires currently in use.

AB The aim of this study was to evaluate the efficacy of an intraoperative monitoring hearing preservation strategy that includes simultaneous recordings of an auditory brainstem response (ABR) and non-invasive electroco-chleography (ECochG). The combined ABR and tympanic membrane (TM) ECochG testing was performed in 74 patients undergoing acoustic neuroma (AN) surgery. In addition, EMG recordings were conducted to monitor the facial nerve function. Hearing was preserved in 19 of the 30 patients with residual hearing prior to surgery (63%), and facial nerve function was maintained in 89% of the patients. In most cases, the presence of both auditory brainstem and TM-ECochG responses at the end of surgery was associated with preservation of postoperative functional hearing; however, eight patients had a TM-ECochG response with a complete loss of the ABR, pointing to deafferentation of the auditory nerve. Tumour size and preoperative hearing thresholds significantly affected the postoperative hearing. The TM-ECochG response yielded large reproducible responses, which, in some patients, was the only way to monitor the auditory function. This auditory monitoring approach offers a valuable auditory tool that helps to improve the hearing preservation during AN surgery.

AB Traditionally, the speech reception threshold (SRT) for sentences in noise is measured in stationary speech-shaped noise; however, non-stationary masking noises are gradually becoming more common. A previous study by Rhebergen et al. (2006) suggested that a learning effect might be present for the SRT in interrupted noise but not in stationary noise. The current study tested if a stable SRT for female or male speech is reached by determining SRTs in listeners with normal hearing in either stationary or 8-Hz interrupted noise after five replications. Contrary to repeated SRT measurements in stationary noise, a significant improvement was observed for SRTs in interrupted noise with replication. For both speech materials, after Five replications, the SRT in interrupted noise improved about 3 to 4 dB in comparison to the first SRT. Stable thresholds seem to be reached after about two replications. This experiment shows that there is a substantial learning effect present in SRT measurements with interrupted noise but not in stationary noise. With non-stationary noise, it is recommended to include a repeated measures design.

AB We examined the ability of twenty-five hearing-impaired and eight normal-hearing listeners to discriminate between release time constants used for compression in hearing aids. The compressor was a standard three-channel system. The stimuli were normal and 'vocoded' sentences from a male and female database. In agreement with other studies looking at different outcomes, performance varied greatly across individuals. This variation was greater in hearing-impaired listeners, for whom the discriminability of a release time of 5 ms from one of 5000 ins (with the attack time fixed at 5 ms) ranged from chance to perfect. This variability was not significantly related to hearing impairment nor to individuals' compression ratios.

AB The issue of cochlear implantation in deaf children with associated disabilities is an emerging subject. Currently, there is no consensus on whether to implant children with multiple impairments; moreover, it may be difficult to evaluate these children with standard tests pre- or post-implantation. In addition, these children often have poor speech perception and language skills, making assessment more difficult. Despite these factors, these children often receive important benefits in daily life, with an overall improvement in quality of life. In the present study, post-implant outcomes of 23 profoundly deaf children with neuropsychiatric disorders were analysed, using objective measures of speech perception, and a questionnaire administered to the parents, aimed at evaluating the benefits in daily life after implantation. The results were quite variable, but overall positive, in terms of speech perception, communication abilities, and improvement in quality of life. The findings add an additional piece of evidence to support the effectiveness of cochlear implantation in these special cases.

AB Caloric restriction is the only known method of increasing lifespan in laboratory animals. The present study was conducted as part of a larger investigation into the effect of caloric restriction on longevity of rhesus monkeys as a model for human aging. This study focused on the effects of caloric restriction and aging on measures of middle-ear function measured with tympanometry. Peak compensated static acoustic admittance (peak Y-tm) tended to be reduced with aging. For tympanometric width (TW), the effect of age was significant with TW increasing with age. Males had a trend of narrower TW than females. A significant age by sex interaction indicated that TW for males stays relatively constant, whereas TW for females increases with age. The equivalent ear canal volume (V,,) was significantly larger in male monkeys than in female monkeys, and marginally larger for the control monkeys than for the caloric restricted monkeys. These results parallel many findings in middle-car function in aging humans. Longitudinal studies are planned.

AB The profession of audiology took root in Brazil nearly a half a century ago and has since blossomed into a flourishing, well-developed field. Currently, audiologists in Brazil work at private institutions, including private medical practices and dedicated speech and hearing clinics. They are also employed in a wide array of public institutions, including community clinics, elementary schools, colleges, and universities. In both the private sector and health clinics, audiologists perform diagnostic evaluations of auditory and vestibular disorders, select and fit hearing aids, and provide aural rehabilitation. At the public level, they assist with workers' health programs, dispense hearing aids, and aural rehabilitation. There is always room to grow, however, and the future of audiology in Brazil holds both challenges and opportunity. The following article will sketch the development of audiology training and practice in Brazil, provide a picture of how the field stands today, and summarize the unique challenges which the profession faces in this large and diverse nation.

AB Digital feedback suppression (DFS) enables users of hearing instruments (HI) to benefit from amplification levels that normally would provoke whistling or poor sound quality. A standardized test for the measurement of DFS benefit is not available. This paper proposes and evaluates an objective method for assessment of extra feedback-free amplification (headroom) provided by a given DFS. It is shown that the whistle-free loop gain can be calculated from data obtained with simulated real-car measurements with the modified pressure method. Test-retest trials were carried out to assess the reliability of the proposed method. Also, a method was developed for defining an appropriate gain level at which the proposed measurement should be carried out, It is concluded that the proposed method needs to be modified to provide useful information.

AB Changes in pitch perception and hearing thresholds over time have been observed in subjects with monaural fluctuating low-frequency hearing loss and Meniere's disease. Long-term suprathreshold audiometry and binaural pitch matches could provide information of these changes. Ten normal subjects were tested for stability of binaural intensity and pitch matches during 9-22 days in their homes with newly developed portable test equipment. Binaural pitch matches were measured using a 0.25- or 1-kHz reference tone presented at 60 dB SPL to one car, and a loudness-matched test tone of adjustable frequency presented to the other ear. The results showed stable binaural intensity matches (individual inter-quartile ranges, IQRs, 1.2 to 5.7 dB), but binaural pitch matches varied greatly (IQR -0.6 to 5.3X, at 0.25 kHz; IQR - 1.6 to 7.9% at I kHz). Binaural pitch-matching was much better in subjects who could define pitch precisely during monaural pitch matching. It was concluded that in future long-term evaluations of patients with fluctuating inner-ear function, binaural intensity snatches could be suitable for all, but binaural pitch matching only for selected patients.

AB The purpose of this study was to provide age specific normative data of clinical gait and balance tests and to determine to what extent gender contributes to differences in postural control. Standing balance and walking performance was tested in 318 asymptomatic adults. The logistic regression, using both 10- and 30-second time limits as a dichotomization point, revealed a significant age effect for standing on foam with eyes closed, tandem Romberg with eyes closed (TR-EC), and one leg stance (eyes open and closed). The actual effect of decline was different for each test. Both tandem gait and dynamic gait index showed a ceiling effect up to 60 years of age, with a rapid decline of performance for subjects in their seventies. Linear regression equations indicated that for both men and women, timed up and go test (TUG) times increased with age, but even older subjects should perform the TUG in 10 seconds or less. Women performed significantly poorer on the TUG and TR-EC (30-second time limit).

AB The goal of this study was to examine the effect of race and gender on transient evoked otoacoustic emission (TEOAE) characteristics. TEOAE amplitude, noise levels, and hearing thresholds were compared in 81 Caucasian (mean age: 27.8 years) and 81 Chinese (mean age: 24.7 years) young adults with normal hearing. TEOAE amplitude was significantly higher in females than males and in the Chinese group than the Caucasian group. Females had better hearing sensitivity than males consistent with TEOAE results. Hearing sensitivity was not statistically different between the two racial groups; however. the interaction between race and hearing thresholds was significant. As the noise levels between the two racial groups were not statistically different, the observed differences are most likely related to differences in middle-ear transmission properties or to differences in cochlear mechanisms. Documentation of gender and racial differences and understanding the underlying mechanism of these differences will not only assist us in understanding how TEOAE will be affected by middle-ear transmission properties but also will help us in establishing normative data in clinical settings.

AB Children with dichotic left ear deficits received intensive training in phase I and phase 11 clinical trials designed to establish the efficacy of directly training dichotic listening. Dichotic verbal material was presented in the sound Field with intensity adjusted separately for each speaker. Output from the right-sided speaker was initially 20 30 din HL lower than for the left-sided speaker, resulting in excellent performance in the left ear. Intensities were adaptively adjusted throughout training in 1, 2, and 5-dB steps in order to keep performance high across dichotic tasks. In both phase 1 (n =8) and phase 11 (n = 13) trials, children demonstrated significant gains in dichotic left ear performance after training. In phase 11, children also demonstrated significant gains in right ear performance. Overall results from the two trials support the feasibility of this training approach for improving a larger than normal interaural asymmetry on dichotic listening tasks. Significant improvements in language comprehension and word recognition in phase 11 suggest that this type of training may also facilitate language skills in some children.

AB The objective of this paper is to present data on the ages of diagnosis and hearing-aid fitting of children with permanent congenital or early-onset hearing loss who were identified through neonatal hearing screening (NHS) programs or medical referral. Data were collected for 709 children born between 1980 and 2003. Children who were screened were diagnosed significantly earlier (mean 6.3 months) than referred children (mean 39.5 months). For the referred children, the ages of diagnosis and amplification improved over time but remained unacceptably high. In addition, there was an inverse relationship between degree of loss and age of diagnosis, with children with lesser degrees of hearing loss identified later than those with severe to profound hearing loss. These results contribute to the evidence that NHS programs lower the ages of diagnosis and amplification and lead to earlier improved hearing. It is argued that early access to hearing should be the desired primary outcome of NHS. The numerous studies demonstrating improved ages of diagnosis resulting from NHS programs constitute adequate evidence to support these initiatives.

AB Serial audiograms were analysed for seven subjects, who were homozygous for the 35delG GJB2 mutation. The criterion for determining progression of hearing loss was at least a 1-dB loss in air conduction pure-tone average-3 (ACPTA-3) or ACPTA-4 per year for 2 to 10 years, with a minimum change of 10 dB ACPTA 3 or 4. Bilateral progression of hearing loss was found in 43% (3/7) of the subjects. A meta-analysis of seven studies with non-overlapping data sets and similar ascertainment criteria indicated that 19% of DFNB1 subjects with GJB2 mutations have progressive hearing loss. These data suggest that it may be incorrect to assume that congenital hearing loss due to this mutation is stable. We recommend rigorous audiologic surveillance for individuals with DFNB1.

AB This study was designed to investigate the feasibility of applying tone-ABRs in the nursery and neonatal intensive care unit (NICU), and to provide normative tone-ABR data from neonates. Normative tone-ABR latency data were determined. The study obtained intensity series of tone-ABRs from thirty preterm neonates and twenty fullterm neonates who had confirmed normal peripheral auditory function after passing both an OAE and ABR screening examination. ABRs were collected in response to 500, 1500, and 4000 Hz tone bursts at 70, 50, 30, and 20 dB nHL. Mean wave V latencies were compared between groups, ears, and by gender. Responses to tone bursts of 20 and 30 dB nHL were detected in 97% and 100% of all ears respectively, in addition to responses to the higher-intensity stimuli. Preterm neonates' ABRs showed significantly longer latencies than those of the full-term infants. Tone-ABR evaluation was found to be both feasible and reliable as a measure of auditory function in neonates.

AB This study was based on a national retrospective analysis of 1400 questionnaires on the causes of deafness in Omani children, collected from 1986 to 2000. It was found that 70% of the deaf children were from parents of consanguineous marriages, and 30% from non-consanguineous unions. In those with consanguineous families 70.16% were first cousin marriages, 17.54% were second cousins, and 10.86% were from the same tribe. The proportion arising from first cousin marriages was higher than the background rate of first cousin marriages in Oman. In the total cohort. 45% had other family members with hearing loss. There was a greater chance of other relatives being affected in the consanguineous group as opposed to the non-consanguineous group (29.7% versus 15.3%). In most cases the affected relative was a deaf sibling (67.8%). We have demonstrated a higher rate of consanguinity amongst parents of deaf children in Oman and suggest this is associated with a higher frequency of autosomal recessive deafness in this paediatric population.

AB The present study evaluated the use of slow rates of stimulus presentation on the accuracy of the N1-P2 cortical response in estimating hearing threshold. Long interstimulus intervals (ISI) allow the non-specific component of the NI response to emerge, believed to reflect widespread cortical arousal that facilitates sensory and motor responses. We examined whether the non-specific NI would be elicited at intensity levels near threshold. Event-related potentials were recorded to 0.5, 1.0, and 4.0-kHz tone bursts with a long ISI (8-12 s) while the eleven subjects read a book. The stimulus level varied from -5 to 45 dB nHL. The 1.0-kHz tone burst was also presented with a shorter ISI (1.5-2.5 s), akin to that typically used in the audiological setting. The amplitude of N1-P2 was significantly enhanced in the long compared to short ISI condition, but, importantly, only for the stimuli with a level >= 25 dB nHL. Therefore, the N1-P2 recorded with long ISIs was not more precise in estimating threshold than that recorded with short ISIs, remaining visible to within 10 dB of behavioural threshold.

AB Recent work shows that variation in adult hearing function is related both to social class of origin and current social class. This study examines how much of this relationship after adjustment for childhood hearing impairment is explicable by occupational noise, current smoking, and alcohol consumption. A cohort of 9023 persons born in the UK during one week in 1958 was followed periodically, and hearing threshold levels (HTLs) were measured at 1 kHz and 4 kHz at age 45 years. Most (71% and 68%, at 1 kHz and 4 kHz respectively) of the relation to social class of origin of adult HTLs remains after adjustment for these other factors. For the relation to current social class, corresponding values are 64% and 44% (though varying by gender). The magnitude of social class effect is comparable to that of occupational noise. Susceptibility to hearing impairment is likely to be appreciably determined in early childhood.

AB The purpose was to investigate the relationship between noise exposure and tinnitus among workers with normal hearing and hearing loss, respectively. We conducted a cross-sectional survey of 752 workers employed at 91 workplaces, that were investigated by means of full work-shift noise levels, questionnaire data, and bilateral pure-tone audiometry. Tinnitus was not associated with the present noise level, the duration of noise exposure, or the cumulative noise exposure if participants had normal hearing. As expected, such trends were demonstrated if participants had a hearing handicap. Based on these data, we will be cautious in ascribing tinnitus to noise exposure in our patients' workplaces if they have a normal audiogram. Furthermore our data indicates no risk of noise-induced tinnitus at exposure levels where no hearing loss would be expected, e.g. as usually encountered in non-industrial workplaces.

AB The purpose of this retrospective study is to examine the possible association between iris pigmentation and susceptibility to noise-induced hearing loss in 2407 noise-exposed workers. The workers were between 16 to 65 years of age and were exposed to 2 to 42 years of work-related noise. Results demonstrated that dark-eyed workers presented a greater percentage of normal pure-tone thresholds than fair-eyed workers. Fair-eyed workers had threshold averages of 25.1 dB (right ear) and 26.0 dB (left ear) at 3, 4, and 6 kHz, which were significantly worse than workers with dark irises, with threshold averages of 15.8 dB and 17.2 dB in the right and left ear, respectively (p0.01). Fair-eyed workers with less than 10 years of noise exposure had the same audiometric pattern as the dark-eyed workers exposed for more than 10 years. Workers not exposed to noise did not present significant differences in their audiometric pattern as a function of eye colour. These results suggest that iris pigmentation may be an additional indication of susceptibility to noise-induced hearing loss.

AB This study aimed to evaluate the effect of impulse noise on otoacoustic emissions (OAEs) while a passive non-linear earplug or an active level-dependent earmuff was worn. Since none of the standardized attenuation measurement techniques, REAT (real ear at threshold), ATF (acoustic test fixture), or MIRE (microphone in real ear), is designed to test both types in real-wearing condition, OAEs, suitable for detecting subtle changes in the functional integrity of the cochlear outer hair cells, are used. First, DPOAEs (distortion product) and TEOAEs (transiently evoked) of 24 subjects were compared before, immediately after gunfire practice, and after one hour of non-exposure. Secondly, both types of OAEs were evaluated in 31 subjects before and after exposure during a five-day military practice. Significant differences existed between the ears in most cases; the emissions from the right ear had a tendency to be more robust. There were no significant changes in OAEs either before and after exposure, or in the second experiment over multiple days. These findings suggest that the HPDs are able to prevent cochlear damage.

   hearing loss
AB The feeling of ear fullness (FEF) occurs frequently in patients with acute sensorineural hearing loss; the same is true for tinnitus (TIN). However, the cause of FEF in these patients is unclear. This study included 171 ears of patients admitted with unilateral sudden deafness to the ENT division of Fukuoka University Hospital between January 2001 and December 2004. The results showed TIN was mainly associated with worse high-frequency hearing thresholds, where hearing loss was relatively severe, and this association became stronger after the hearing threshold stabilized. FEF was associated with the low-frequency region, where hearing loss was relatively mild, and this association disappeared after the hearing threshold stabilized. In conclusion, TIN is thought to originate in the region where hair cells are impaired; in contrast, FEF may originate from some functional factor rather than an organic lesion of the cochlea.

ID SIGNIFICANT OTHERS; PROFILE; AID
AB The prevalence of hearing impairment (HI) in older people and its detrimental effects on their quality of life and well-being is well known. To date however, there have been few studies investigating the impact on the person's spouse. To investigate this topic, a qualitative study consisting of in-depth interviews was conducted with five female and five male spouses of older people with HI. The aims of the study were: (1) to describe the spouses' experiences of living with someone with a HI; (2) to describe the effect of HI on the couples' communication and relationship; and (3) to identify coping strategies adopted by spouses. An interpretive analysis revealed four themes that described the experience of spouses of older people with HI: (1) the broad ranging effects of the HI on the spouses' everyday lives; (2) the spouses' need to constantly adapt to their partners' HI; (3) the effect of acceptance of the HI on the spouse; and (4) the impact of ageing and retirement. Spouses in this study experienced a wide range of effects as a result of their partners' HI. Implications for audiological rehabilitation are discussed.

AB It is generally recognized that poor results of speech-in-noise tests by hearing-impaired persons cannot be fully explained by the elevated pure-tone hearing threshold. Plomp has shown, among others, that an additional factor has to be taken into account, often referred to in general terms as distortion. In an attempt to specify auditory and cognitive functions which may underlie this distortion, various studies on this topic originating from Plomp's research group are reviewed, as well as other relevant studies which provide quantitative data on the correlations between various types of auditory or cognitive tests (the predictor tests) and speech-in-noise tests. The predictor variables considered include, besides the pure-tone audiogram, measures of spectral and temporal resolution, intensity difference limen, age, and some cognitive aspects. The results indicate that, by and large, these variables fall short in fully explaining the variance observed in the speech-in-noise tests. This strongly suggests that the predictor variables considered so far do not cover all sources of variance relevant for speech reception in noise.

AB Binaural abilities are difficult to assess, yet important to understand, in the course of rehabilitating bilateral cochlear implantees. One purpose of this research was to develop a binaural assessment methodology using direct electrical input to the cochlear implant, ''direct connect assessment'', pre-processed by appropriate headrelated transfer functions (HRTFs) to simulate the binaural cues for spatial release from masking and sound localization. A second purpose was to create and evaluate new, modified rules for adaptively measuring the speech reception threshold in noise with the Hearing In Noise Test (HINT) for use with cochlear implant subjects. A third purpose was to develop a new sound localization protocol whose difficulty is adjusted to the sound localization ability of the individual cochlear implant subject. These new protocols were combined with the direct connect method and evaluated in acoustic hearing subjects and cochlear implant subjects. HINT thresholds and sound localization scores measured in the sound field and with the direct connect method did not differ significantly and were highly correlated in both groups. Measures of spatial release from masking, head shadow effects, binaural squelch, and binaural summation derived from the thresholds also were comparable for both methods. The alternative adaptive rules for HINT were found to measure different points on the same performance-intensity function. These rules allowed all cochlear implant subjects in the study to be tested adaptively and their thresholds to be compared to norms. Sound localization was measured successfully in all subjects with a sector localization protocol whose difficulty is to be adjusted to the localization ability of the subject. This protocol reduced by one-third to one-half the time required to complete the assessment of the localization ability.

AB This study investigated the effects of adaptive dynamic range optimization (ADRO) processing for six bimodal listeners who used a hearing aid in one ear and a cochlear implant in the other. 'Bimodal' refers to the use of acoustic and electrical stimulation together. Bimodal speech recognition thresholds with the Japanese hearing in noise test were significantly lower for two ADRO devices than two non-ADRO devices in quiet, in noise from the front, and in noise from the implanted side. When the noise was presented from the non-implanted side there was no significant difference between the ADRO and non-ADRO conditions. The hearing aid measure of contrast questionnaire indicated that participants preferred ADRO in 77.3% of situations. ADRO was especially preferred in more difficult situations. The ADRO processing was designed for use in bimodal prostheses, and this study confirmed that speech intelligibility and sound quality improvements are obtainable by using ADRO in a bimodal context.

AB Effective communication is a crucial requirement in many workplaces to ensure safe and effective operations. Often, critical verbal communications are carried out in noise, which can be very challenging, particularly for individuals with hearing loss. Diagnostic measures of hearing, such as the audiogram, are not adequate to make accurate predictions of speech intelligibility in real-world environments for specific workers, and thus are not generally suitable as a basis for making employment decisions. Instead, the Hearing in Noise Test (HINT) has been identified and validated for use in predicting speech intelligibility in a wide range of communication environments. The approach to validation of the HINT takes into account the expected voice level of the talker, the communication distance between the talker and the listener, and a statistical model of speech intelligibility in real-world occupational noises. For each hearing-critical task, a HINT screening threshold score is derived upon specification of the minimum level of performance required of the workers. The HINT is available in several languages, so the tools developed are applicable in a wide range of settings, including multilingual workplaces.

AB Differences in performance between unaided and aided performance (omnidirectional and directional) were measured using an open-fit behind-the-ear (BTE) hearing aid. Twenty-six subjects without prior experience with amplification were fitted bilaterally using the manufacturer's recommended procedure. After wearing the hearing aids for one week, the fitting parameters were fine-tuned, based on subjective comments. Four weeks later, differences in performance between unaided and aided (omnidirectional and directional) were assessed by measuring reception thresholds for sentences (RTS in dB), using HINT sentences presented at 0 with R-Space (TM) restaurant noise held constant at 65dBA and presented via eight loudspeakers set 45 apart. In addition, the APHAB was administered to assess subjective impressions of the experimental aid.
   Results revealed that significant differences in RTS (in dB) were present between directional and omnidirectional performance, as well as directional and unaided performance. Aided omnidirectional performance, however, was not significantly different from unaided performance. These findings suggest for the hearing aids and experimental condition used in this study, a patient would require directional microphones in order to perform significantly better than unaided or aided with omnidirectional microphones, and that performance with an omnidirectional microphone would not be significantly better than unaided. Finally, the APHAB-aided scores were significantly better than unaided scores for the EC, BN, RV, and AV subscales indicating the subjects, on average, perceived the experimental aid to provide significantly better performance than unaided, and that aided performance was more aversive than unaided.

AB Accurate pitch perception on the basis of fundamental frequency patterns is essential for the processing of lexical tones in tonal languages such as Cantonese. Speech intelligibility in Cantonese-speaking CI recipients was compared using current signal processing strategies, which typically result in poor pitch perception, and a new strategy, known as the multi-channel envelope modulation (MEM) strategy, was designed to enhance temporal periodicity cues to the fundamental frequency. Performance of nine postlingually hearing-impaired adult cochlear implant users was measured twice using each strategy, initially after a four week trial, and again after two weeks of use with each strategy. Speech intelligibility in speech-spectrum shaped noise was measured using the Cantonese hearing in noise test. A fixed noise level of 65 dB A was used and the signal-to-noise ratios were fixed at either +10, +15, or +20 dB, depending on the baseline performance of individual subjects using the clinical processor. Self-reported benefit in 18 listening situations and overall preference for strategies were obtained at the end of these trial periods. Results showed poorer speech intelligibility with CIS while results obtained using ACE and MEM were comparable. Unfamiliar place coding might have contributed to poorer performance using CIS. Self-reported benefit across strategies did not differ in most listening situations. Participants preferred ACE for listening overall in daily situations, and a few preferred MEM in noise. Whilst the results did not demonstrate any advantages for speech recognition in noise when using MEM compared to ACE, no degradation in performance was observed. This implies that the form of processing employed by MEM retains similar segmental information to that provided by ACE and that potentially, future variations/optimizations of MEM may lead to some improvement in tone perception.

TI LIST and LINT: Sentences and numbers for quantifying speech
   understanding in severely impaired listeners for Flanders and the
   Netherlands
SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
DE speech intelligibility; sentences; numbers
ID RECEPTION THRESHOLD; NOISE TEST; HEARING; HINT
AB A Dutch sentence test (LIST) and a Dutch number test (LINT) have been developed and validated for the accurate measurement of speech reception thresholds (SRT) in quiet and in noise with severely hearing-impaired individuals and cochlear implant recipients in Flanders and the Netherlands. The LIST consists of 35 lists of 10 sentences of equal known difficulty uttered by a female speaker; while the LINT consists of 400 numbers (1-100) by two male and two female speakers. Normative values were determined at fixed S/N ratios and using the adaptive method (Plomp Mimpen, 1979), yielding identical results for SRT and slope. For the LIST, average fitted SRTs were 27.1 (0.9) dB SPL in quiet and -7.8 dB (0.2) SNR in noise. In addition, the LIST in noise displayed a steep discrimination function (17%/dB) and good reliability (within-subject standard deviation=1.2 dB). For the LINT average fitted SRTs in quiet were 20.7 (0.9) dB SPL and about -9.0 dB SNR in noise. Again, the slopes of the performance intensity functions were relatively steep, i.e. 8.5%/dB in quiet and 15.2%/dB in noise, suggesting that the LINT is accurate and efficient and thus capable of reflecting subtle changes in performance. First data with cochlear implanted subjects show that both LIST and LINT are feasible and are capable of mapping a large range of hearing disabilities.

AB The Special Olympics Healthy Hearing Program provides a unique opportunity to determine the hearing service needs of individuals with mild intellectual disabilities participating in athletic endeavors in countries throughout the world. The Healthy Hearing Program screened 855 of 1800 athletes with intellectual disability over a period of a week at Nagano, Japan. Of 855 athletes screened, 58% passed the DPOAE screen and therefore required no further testing. Of the remaining 42%, 186 did not pass pure-tone screening. This number of athletes represents 21.8% of all athletes screened. Tympanometry outcomes for the 186 athletes failing pure-tone screening showed 56% (104) also failing this measure of middle-ear function. 65% of these 104 athletes' outer ear canals were blocked/partially-blocked with cerumen. This amount is in contrast to the 38% presence of cerumen for the 82 athletes failing pure-tone screening but passing tympanometry.

ID ANCHORED HEARING-AIDS; AUDIOMETRIC EVALUATION; VIBRATOR PLACEMENT;

   LOCALIZATION; THRESHOLDS
AB This study tested the prediction that interaural phase differences (IPDs) are converted to interaural level differences (ILDs) with bilateral bone-conduction stimulation due to the effects of acoustic interference arising from transcranial transmission. Seven normal-hearing listeners judged the lateral position of 3000-6000-Hz pure tones, presented via bone vibrators on the mastoids, as a function of IPD. Evidence for lateralization was obtained in five listeners despite humans being insensitive to IPD in pure tones at these frequencies. The direction of lateralization depended on frequency, as well as IPD, for three listeners. It is argued that these findings are consistent with the conversion of external IPD to internal ILD during transcranial transmission. Inter-individual variation in lateralization was apparent and no evidence of lateralization was found in two listeners at the frequency tested, which may reflect, at least in part, inter-individual variation in transcranial transmission properties. The notion that external IPD within the waveform fine-structure at high-frequencies does not influence localization with air conduction may not apply to bone conduction due to the acoustic interference effects.

AB The purpose of this study was to measure changes in intensity and pitch matches to better assess disease activity in fluctuating hearing loss. Long-term suprathreshold audiometry was carried out at home on a subject with a unilateral fluctuating low-frequency hearing loss during a period when the subject demonstrated no symptoms and a period when the subject reported hearing loss, aural pressure, and tinnitus. Daily measurements of binaural intensity and pitch matches were made. Day-to-day fluctuations were clearly accentuated during the period when the subject experienced symptoms. Specifically, deviations from the reference tone were only observed for binaural pitch matches at 1 kHz during the period without symptoms; however, highly fluctuating binaural intensity and pitch matches were observed at 0.25 kHz during the period with symptoms. These fluctuations were not observed in a normal-hearing group. The results suggest that long-term measurements of binaural intensity and pitch matches can be used to monitor disease activity in fluctuating low-frequency hearing loss.

AB A new questionnaire, developed to investigate self-reported hearing difficulties in unilateral deafness, was completed by 221 post-surgical vestibular schwannoma patients. Results were compared to a group of 51 normal hearers and 12 patients with severe unilateral deafness from other causes. The vestibular schwannoma patients rated their post surgical hearing as profoundly deaf in the operated ear, and worse than pre-surgical in the other. Factor analysis of the results revealed a general hearing factor and five factors, indirect listening, direct listening, face-to-face listening, noise and distance, and localization, representing performance in specific listening situations. Two factors, direct listening and face-to-face listening have not been commented upon previously in the literature. No differences were found between the hearing-impaired groups on any of the factors. Both groups gave ratings significantly worse than the normal hearers on all factors, and rated themselves worst on indirect listening, in which speech comes from the impaired side. It was concluded that severe unilateral deafness is a significant disability, requiring more attention in clinical practice, particularly with pre-surgical vestibular schwannoma patients.

AB Input/output functions of the simultaneously recorded acoustic distortion product otoacoustic emissions (DPOAE) and neural frequency following-response distortion products (FFR-DP) at 2f1-f2 were evaluated to determine if these two representations of cochlear nonlinearity exhibit similar response behavior, which would suggest shared cochlear generators. Responses were recorded from normal-hearing adults for a tone burst stimulus pair (F1: 500 Hz; F2: 612 Hz) at 40-70 dB nHL. DPOAE responses were recorded from the ear canal, and FFR responses were recorded differentially from scalp electrodes, representing a vertical configuration. The input/output function for FFR-DP revealed a compressive saturating nonlinearity, whereas the DPOAE input/output function exhibited a linear growth at higher intensities following a compressive behavior at moderate levels. Results appear to suggest that cochlear generators may be contributing differentially to the acoustic and the neural distortion products. Also, FFR-DP responses appeared more identifiable and less variable, particularly at lower stimulus levels, than the corresponding DPOAE. These findings may point to a potential benefit of applying FFR testing to complement DPOAE in evaluating cochlear function at low frequencies.

AB Auditory evoked potential (AEP) recordings often require subjects to ignore the stimuli and stay awake. In the present experiment, early (ABR), middle (MLR), and late latency (LLR) AEPs were recorded to compare the effect of five different distracting tasks: (1) doing nothing eyes open, (2) reading, (3) watching a movie, (4) solving a three-digit sum, and (5) doing nothing eyes closed (or counting the stimuli for LLR). Results showed that neither the amplitudes nor the latencies of the ABR, MLR, or LLR were affected by task. However, the amount of pre-stimulus activity (noise) or amplitude rejection was significantly and differently affected by the distracting task. For the ABR, the math task was the noisiest but, for the MLR, the amount of noise was greater when watching a movie. As for the LLR, reading and watching a movie yielded the lowest percentage of rejected traces. In conclusion, the choice of distracting task depends on the AEP being measured and should be chosen to improve the quality of the AEP traces and thus reduce recording time.

AB The purpose of this study was to determine the impact of a digital noise reduction (DNR) scheme implemented in a current commercial hearing aid. In a double-blinded design, three conditions of onset time (4, 8, 16 seconds) were randomly assigned to the 25 subjects, plus one condition wherein the noise-reduction feature was disengaged. Subsequently, a fifth trial/condition, wherein the subject had access to three memories in which the different onsets were programmed, was carried out. For each of the five conditions, the subjects had an at-home trial, prior to obtaining self-report measures. Laboratory measures of speech perception showed no effect of the DNR, with or without the provision of visual cues. Laboratory-based ratings of ease of listening showed DNR-on (all onset times) to be rated significantly better than DNR-off; for ratings of listening comfort, the 4-second onset time was rated significantly lower (poorer) than the 8-second onset or the DNR-off condition; for ratings of sound quality, DNR-on or -off had no differential effect. Self-report measures indicated significantly higher aversiveness in the DNR-off condition compared to the pre-test scores

AB This study examined the effect of variations in hearing-aid frequency response on real-life functional performance of children with severe to profound hearing loss. A cross-over design was used in a double-blind comparison of the NAL prescription with alternatives that produced either a BOOST or a CUT (6dB/octave from 0.5 to 2kHz), relative to the NAL response. The functional performance of 30 children (aged 7 months to 16 years) when wearing hearing aids adjusted to each response over two to four weeks was assessed by using parents' and teachers' observations (PEACH and TEACH scales). Intelligibility judgments and self-reports were also obtained from school-aged children. Results indicated that on average, variations in frequency response resulted in differences in functional performance in real life. There were significant correlations between PEACH and TEACH, and also between children's intelligibility judgments and subjective reports from children and their parents and teachers. The findings support the use of the NAL response for initial fitting, and the evaluation of children's amplification needs by a systematic use of parents' and teachers' observations.

AB The objective of this study was to compare bone-conduction (BC) auditory steady-state responses (ASSR) for infants and adults with normal hearing to investigate the time course of maturation of BC hearing sensitivity. Bone-conduction multiple ASSRs were recorded in 0-11-month-old (n=35), and 12-24-month-old infants (n=13), and adults (n=18). Low-frequency BC ASSR thresholds increased with age, whereas, high-frequency ASSR thresholds were unaffected by age except for a slight improvement at 2000Hz. Compared to adults, BC ASSR amplitudes for young infants were larger for low frequencies, whereas, their amplitudes were smaller or similar for high frequencies. Compared to adults, young infants are much more sensitive to low-frequency BC stimuli, and probably more sensitive to high-frequency BC stimuli; these differences between infants and adults persist until at least two years of age. Different 'normal levels' for infants of different ages must be used and are proposed in this study.

AB The test-retest reliability of the auditory steady-state response (ASSR) has received limited attention. Therefore, the aim was to assess the test-retest reliability of an 80-Hz multiple-ASSR system in normal-hearing subjects by a comprehensive set of statistical methods. Twenty-nine participants (15 females) aged between 18 and 30 years contributed to two sessions (test-retest), and the ASSR thresholds were determined with a descending search protocol using a 10-dB precision. The test-retest reliability was assessed by a three-layered approach which consisted of Pearson product-moment correlation, analysis of variance (ANOVA), and standard error of measurement (SEM). The correlations for ASSR thresholds ranged from poor (0.34) for 500 Hz CF to moderate (0.55) for 1000, 2000, and 4000 Hz CF. A two-way ANOVA of the difference scores (ASSR threshold minus behavioral threshold) demonstrated no significant difference between test and retest. The SEM determined the normal tolerance for clinical error of repeated thresholds and the ASSR SEM values fell well within 10 dB HL. This investigation shows that the multiple ASSR-technique produces a clinically acceptable test-retest reliability for normal-hearing adults.

AB The objective of this study was to improve the sensitivity of ABR recordings in newborns via a procedure that utilizes the ear canal as a recording site. Conventional recordings were compared to ear canal recordings of the ABR in 45 normally-hearing newborns who passed their newborn hearing screening. Responses were obtained at stimulus levels of 80, 60, 40, and 20 dBnHL using forehead (+) to ear canal (-), versus forehead (+) to mastoid (-) electrode configurations. ABR parameters evaluated included measurement of component amplitudes of wave I and V, absolute latencies of I and V, the I-V interwave interval, and amplitude ratio. At stimulus levels of 80, 60, and 40 dBnHL, wave I amplitude was significantly larger using the ear canal configuration. This investigation shows that the amplitude of wave I is significantly larger and easier to identify when the ear canal is used as one of the recording sites in comparison to more conventional scalp (mastoid) recordings.

AB Patients fitted with one (CI) versus two (CI+CI) cochlear implants, and those fitted with one implant who retain a hearing aid in the non-implanted ear (CI+HA), were compared using the speech, spatial, and qualities of hearing scale (SSQ) (Gatehouse Noble, 2004). The CI+CI profile yielded significantly higher ability ratings than the CI profile in the spatial hearing domain, and on most aspects of other qualities of hearing (segregation, naturalness, and listening effort). A subset of patients completed the SSQ prior to implantation, and the CI+CI profile showed consistently greater improvement than the CI profile across all domains. Patients in the CI+HA group self-rated no differently from the CI group, post-implant. Measured speech perception and localization performance showed some parallels with the self-rating outcomes. Overall, a unilateral CI provided significant benefit across most hearing functions reflected in the SSQ. Bilateral implantation offered further benefit across a substantial range of those functions.

AB The aim was to study hearing impairment in commercial pilots. A total of 634 male and 30 female pilots (N=664) in a Swedish airline company underwent repeated audiological tests during the period 1974-2005. The last test was used to study hearing impairment. The mean values for the hearing test at 3, 4, and 6 kHz were used for the ear with worse hearing impairment. Data was compared with a general adult Swedish population (n=603) not occupationally exposed to noise. Equivalent noise levels gate to gate (Leq) were measured in the cockpit of different aircraft. Leq was 75-81 dB (A), peak exposures were 105 dB (A) from the cabin call signal. Median values were similar as in the reference group at all ages. There was no association between years of employment, tobacco smoking, and hearing impairment, when adjusted for age and gender by multiple logistic regressions analysis. In conclusion, pilots are exposed to equivalent noise levels below the current Swedish occupational standard of 85 dB (A), with short peak exposures above the standard, and have normal age-matched hearing thresholds.

AB Audiograms measured with a high frequency resolution often show quasi-periodic ripples of up to 15dB in normal-hearing listeners. This fine structure of the threshold in quiet is commonly associated with the active processes in the cochlea. Therefore its absence is discussed in the literature as an indicator of cochlear vulnerability. In order to enable a quick detection and an objective quantification of threshold fine structure, two instruments are introduced and evaluated in this article: (1) a high-resolution tracking method for measuring fine structure ('FINESS'), and (2) an automatic fine-structure detector ('FINESS-detector'). The method is tested on 22 subjects for its reliability, its accuracy, and drifts with frequency by analysing test/retest experiments and by comparing the measured thresholds to results from a reference procedure. The results indicate that FINESS and the FINESS-detector are suitable techniques for the measurement and detection of threshold fine structure that may help to investigate further into whether fine structure is a sensitive tool for the detection of an early hearing loss.

AB Hearing impairment (HI) is the most frequent sensory disorder, with a genetic etiology in 50% of all cases, due to mutations in 44 identified genes. Autosomal recessive inheritance explains the majority, with GJB2 (connexin 26) mutations accounting for 15-50% of paediatric HI. Delayed presentation of HI to 11-60 months in cases of biallelic GJB2 mutations is a concern, necessitating a good audiological follow-up in addition to neonatal hearing screening. Providing a genetic diagnosis in congenital HI has implications for the prognosis, the possible risk of associated medical manifestations, and precise genetic counseling of the family, and should be integrated into the medical examinations done in order to diagnose syndromic features. Large-scale mutation detection methods, such as micro arrays, are promising for wider genetic testing, but few studies on their clinical utility have been published, so far. Limitations of interpretation of genetic test results, combined with significant ethical issues, currently do not justify to institute genetic screening for GJB2 mutations in neonates before a diagnosis of HI is established.

AB Current considerations in pediatric speech perception assessment are highlighted in this article with a focus on specific test principles and variables that must be addressed when evaluating speech perception performance in children. Existing test materials are reviewed with an emphasis on the level of sensitivity and standardization that they have for accurate assessment of a child's speech perception performance. A test battery approach is advocated because speech perception is an abstract construct, and in order to provide a comprehensive assessment of a child's capabilities, information is needed from several sources of concrete data. The importance of ongoing speech perception assessment in children is also emphasized because a child's progress over time must be monitored to determine if improvements need to be made with amplification and intervention efforts. Results from pediatric speech perception assessments can provide practical information regarding the prognosis of speech, language, reading, and cognitive abilities of children as well as steps that need to be taken in the intervention process.

AB In 1984 the Bone-Anchored Hearing Aid, or BAHA, system was introduced. Its transducer is coupled directly to the skull percutaneously to form a highly effective bone-conduction hearing device. Clinical studies on adults with conductive hearing loss have shown that the BAHA system outperforms conventional bone-conduction hearing aids. Therefore, the next step was to apply the BAHA system in children with congenital or acquired conductive hearing loss. Reviewed data showed that, on average, such children benefited significantly more from the BAHA than from reconstructive surgery. Thus, BAHA application appears to be the best option to achieve normal communication and speech and language development in children with bilateral conductive hearing loss. However, in children under the age of three to four years, a conventional solution must be applied, e.g. a bone conductor with a transcutaneous coupling, because they are too young to undergo BAHA implant surgery. In the case of unilateral congenital conductive hearing loss, there is no convincing evidence in the clinical literature for early intervention. In summary, the BAHA system can be considered a new, indispensable tool for children with bilateral conductive hearing loss.

AB Recent studies show that several audiovestibular pathologies in the paediatric population may be immune-mediated. This is even more probable if the pathology is associated with a coexisting systemic autoimmune disorder. At this time, however, the current literature is limited to a few case reports, and little is known with regard to prevalence, diagnosis, and management of immune-mediated inner-ear disorders in children. This review aims to shed some light on clinical presentation, diagnosis, and treatment of paediatric immune-mediated inner-ear disorders. Sudden and progressive sensorineural hearing loss is discussed, in addition to some of the systemic autoimmune disorders commonly associated with immune-mediated audiovestibular pathology such as Cogan's syndrome, systemic lupus erythematosus, Behcet's disease, Sjogren's syndrome, and juvenile idiopathic arthritis.

AB When vertigo and dizziness are diagnosed in a child, this is a matter of concern for the physician and the child's family. Prior to a comprehensive otological, neurological, and vestibular clinical examination, physicians often request CT or MRI scanning, although in most cases such expensive testing is unnecessary. The present work is based on the results of a 14-year study conducted with a sample of more than 2,000 children referred for vertigo and balance disorders to the functional vestibular evaluation unit of the ENT pediatric department at Robert Debre Hospital (Paris). The clinical signs of vestibular deficit and the most frequent aetiologies of vertigo and dizziness in children are detailed (migraine equivalent, ophthalmologic disorders, benign paroxysmal idiopathic pediatric vertigo, and temporal bone fracture), which has been helpful in determining the best diagnostic procedure and therapy for vertigo in children.

AB Dizziness can be caused by a variety of peripheral vestibular, central, and systemic disease processes. Eustachian tube dysfunction with and without middle-ear effusion has been considered one of the most common causes of balance disturbances in young children. Several studies have indicated that during an episode of otitis media the child's balance deteriorates and the child may become clumsy and fall more often. Thus, not only the adverse effect on hearing should be considered in the management of a child with otitis media, but also the child's balance.

ID MOTOR DEVELOPMENT; COCHLEAR IMPLANT; INFANTS
AB Congenitally deaf infants and children commonly suffer vestibular failure in both ears, and impairment of postural control, locomotion, and gait. The development of gross motor functions, such as head control, sitting, and walking is likely to be delayed, but fine motor function is usually preserved unless disorders of the central nervous system are present. These children can eventually catch up with their normal peers in terms of development and growth as a result of central vestibular compensation. The visual and somatosensory systems, pyramidal and extrapyramidal motor system (cerebellum, basal ganglia, cerebrum) and intellectual development, compensate for vestibular failure in infants and children with congenitally hypoactive or absent function of the semicircular canals and otolith organs.

AB The performance of mental alerting during caloric testing has always been considered important, however its use/benefit during electronystagmography (ENG)/videonystagmography (VNG) testing has been questioned. The aim of this study was to investigate the effect of mental alerting tasks on peripheral type vestibular nystagmus recorded during ENG. Thirty patients with significant spontaneous/gaze or positional nystagmus (slow phase velocity >= 6 degrees/s) were recruited from consecutive referrals for vestibular assessment. Nystagmus was recorded by ENG both in the presence and absence of mental alerting for each patient. Investigation of nystagmus by analysis of variance (ANOVA) revealed significantly larger nystagmus (higher value SPV) with mental alerting than with no alerting (p <0.001), and for some patients nystagmus traces were reduced to a flat line (no nystagmus) with no alerting. The study demonstrates the importance of mental alerting in helping overcome central suppression of nystagmus and highlights its importance to help identify peripheral type nystagmus during ENG.

AB The presentation of contralateral noise during the recording of transient evoked otoacoustic emissions (TEOAEs) reduces the amplitude of the TEOAE in normally-hearing adults. This is known as TEOAE suppression. The present study investigated TEOAE suppression in 18 adults with learning disabilities (LDs) compared to 18 adults without LDs. TEOAEs were elicited by 60 dB p.e. SPL clicks and were suppressed by the presentation of 60 dB SPL contralateral broadband noise. Suppression was measured as a change in the overall TEOAE response amplitude, and also analysed in 2-ms epochs representing different TEOAE frequency-response bands. A significant interaction was evident between group type and ear tested. Participants in the control group had right ear dominance for the suppression effect, whereas the left ear was found to be dominant for the LD group. These findings suggest a mechanism of the medial olivary cochlear bundle and efferent auditory pathway that differs in those with LD compared to those with typical learning abilities.

AB Tympanometry is a non-invasive, quick, and inexpensive method for examining the middle-ear function. Its limited value in differentiating otosclerotic from normal middle ears caused researchers to develop new methods for evaluation of middle ears. Resonant frequency had been found to be higher in otosclerotic middle ears than normals. We conducted multiple-frequency tympanometry measurements in 25 surgically confirmed otosclerotic ears and 100 normal ears. Mean middle-ear resonant frequency for the otosclerotic group was found to be 1190 Hz and mean middle-ear resonant frequency of the control group was 934.6 Hz (p <0.001). With a cut off value of 1025 Hz (based on 95% confidence interval), sensitivity was 80% and specificity was 82%. The present findings confirm the advantage of the resonant frequency estimation over conventional tympanometry in detecting middle-ear status and mechanics in patients with otosclerosis. As a conclusion, detecting resonant frequency when evaluating patients for otosclerosis must be an essential part of examination. Nevertheless, further investigation is necessary for better diagnosis of otosclerosis preoperatively.

AB This study aimed to determine whether gain adaptation occurs, and at which frequency bands, among new hearing aid (HA) users. Fifty new and 26 experienced HA users were fitted with three listening programs (NAL-NL1 and NAL-NL1 with low- and high-frequency cuts) in the same hearing instrument family. Real-life gain preferences and comfortable loudness levels were measured one, four, and 13 months post-fitting for the new HA users, and one month post-fitting for the experienced HA users. Relative to experienced HA users, new HA users preferred progressively less overall gain than prescribed as the hearing loss became more severe. Gain adaptation occurred in new HA users with greater hearing loss, but was not complete 13 months post-fitting, and was not explained by changes in loudness perception. Preferences for a high-frequency gain cut by half of all study participants could not be predicted from audiological data. Gain adaptation management is recommended for new HA users with more than a mild hearing loss.

AB The aim of this study was to describe the adaptation to bilateral cochlear implant use and the perceptual benefits demonstrated by 10 children who were successful users of a first implant when a second was received before four years of age. Although one subject rejected the second implant at switch-on, the nine subjects who accepted the device adapted easily to bilateral implant use and developed useful listening skills with the second implant. Tests of localization (left versus right) and speech detection in noise were administered in the unilateral and bilateral conditions, usually after six months experience. All subjects demonstrated some bilateral benefit on speech detection testing (mostly due to a headshadow effect), and the majority localized left versus right. Results suggested that outcomes may be negatively impacted by increased age at the time of second implant switch-on. The majority of the subjects adapted well to bilateral implant use within six months and demonstrated some perceptual benefit and, according to subjective parent reports, improved daily functioning; however, device rejection must be discussed pre-operatively as a possibility.

ID HEARING IMPAIRMENT; DEVELOPING-COUNTRIES
AB This paper describes the international education and practice of audiology with the broader aim of proposing possible cost-effective and sustainable education models to address the current situation. Major audiology organizations worldwide were surveyed from February 2005 to May 2007, and organizations from 62 countries (78% of the world population) returned a completed survey. Overall, the results suggested a wide range of professionals providing hearing health care, and 86% of the respondents reported a need for more audiologists. There was also considerable variation in the scope of practice among the different hearing health care professionals, and the minimum education levels of audiologists with similar scopes of practice. The countries surveyed fell into four broad categories in terms of professional resources, and the results highlighted the urgent need for forward planning at both national and international levels. The study highlights options for addressing some of the challenges in educating audiologists and the provision of hearing health care services globally.

ID SOUND PRESSURE LEVELS; INSERT EARPHONES; REFERENCE ZERO; CALIBRATION
AB Hearing thresholds for clicks and tonebursts were measured on 26 otologically normal persons (age 18-25 years) using the earphones Sennheiser HDA 200 and Telephonics TDH 39. The test signals are specified in IEC 60645-3 and in ISO 389-9. The acoustic test signals were presented both as a single stimulus and as repeated stimuli with the repetition rate of 20 Hz. The frequencies used for the toneburst were: 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. Test signals and measurement methods were all in accordance with the recommendations given in ISO 389-9: Preferred test conditions for the determination of reference hearing threshold levels. The results are given as peak-to-peak equivalent threshold sound pressure levels (peETSPL). The results are in good agreement with other sparse results from literature and are part of the basis for the ISO 389-6 standard from 2007.

AB Thirteen subjects made consecutive long-term recordings of binaural intensity and pitch matches in their homes using portable equipment to assess hearing fluctuations. Two groups of subjects were used; one with monaural fluctuating low-frequency hearing loss (FLFHL) without vertigo, and one with monaural Meniere's disease (i.e. FLFHL with vertigo). The subjects measured binaural pitch matches using a 0.25- or 1-kHz reference tone presented at 60 dB SPL to one ear, and a loudness-matched test tone of adjustable frequency presented to the other ear during one to several weeks. Their results were compared to those previously obtained from ten normal-hearing subjects. Both groups of subjects showed fluctuations in binaural intensity and pitch matches not seen in the normal-hearing group. We calculated the average day-to-day difference in matched intensity and frequency for each subject's test period as a measure of disease activity. This measure indicated that the group with Meniere's disease has a higher disease activity than the group with FLFHL without vertigo, and that both these groups of subjects had higher disease activity than normal-hearing subjects.

AB The current study assessed the responses from a survey titled 'Life and Health - Young People 2005', completed by 2878 15-16-year-old adolescents in mainstream schools in the county of Orebro, Sweden. Thirty-nine percent of students with hearing loss (slight, mild, or moderate) and 6% of students with normal hearing reported tinnitus often or always during the past three months. Almost no gender difference was observed among students with normal-hearing reporting tinnitus (boys 6.3%, girls 5.6%); however, a gender difference was noticed among hard-of-hearing (HH) students (boys 50%, girls 28%). Adolescents with both hearing loss and tinnitus reported considerably higher scores for mental health symptoms, substance use, and school problems than other students. Anxiety in the past three months, male gender, and alcohol consumption in the past year were associated with tinnitus in HH students; irritation and anxiety in the past three months, disability, use of illicit drugs, and truancy predicted tinnitus in the normal-hearing group. Consequently, students with a hearing loss and tinnitus are at high risk and should be monitored for subsequent problems.

AB We investigated the influence of cisplatin on spontaneous otoacoustic emissions (SOAEs) by measuring SOAEs, before and after cisplatin administration, in 18 ears of nine patients (one female and eight males) who had received chemotherapy with cisplatin for a brain tumor. No hearing loss was observed after cisplatin administration in eight ears. Before cisplatin administration SOAE was present in four out of these eight ears, and only mild frequency fluctuation was observed even after administration. In 10 ears, sensory neural hearing loss was observed after cisplatin administration. Before cisplatin administration SOAE was present in four out of these 10 ears, and SOAE decreased or disappeared in three ears after administration. In two ears, SOAE was not present before cisplatin administration, but newly appeared after administration. It was indicated that SOAE principally disappeared at the frequencies where the region of the outer hair cells responsible for the same frequencies was injured, but new SOAEs appeared at the frequencies where the region of the outer hair cells was not injured after cisplatin administration.

AB Pathogenic mitochondrial DNA mutations are most often implicated in inherited and acquired hearing impairment. The current review mainly focuses on the 12S rRNA mitochondrial gene mutations associated with non-syndromic deafness without or after aminoglycosides exposure. Aminoglycoside-induced and nonsyndromic deafness has been shown to have a genetic susceptibility and the pathogenic mitochondrial 12S rRNA A1555G mutation was identified as the primary factor underlying the hearing loss in many familial as well as in genetically unrelated cases, particularly in Asian populations where aminoglycoside antibiotics are commonly used even for minor infections. Many families were shown to transmit the aminoglycoside ototoxicity through matrilineal inheritance and the A1555G mutation in the 12S rRNA gene was frequently identified. The aminoglycoside antibiotics are believed to target the mitochondrial ribosome in the cochlea resulting in abnormal RNA processing or decreased efficiency of translation thereby leading to irreversible auditory dysfunction. Such cases may have a genetic predisposition to aminoglycoside ototoxicity following autosomal dominant, autosomal recessive, X-linked, or mitochondrial pattern of inheritance.

AB The effect of inverting electrode location and stimulus perceptibility on the presence of the mismatch negativity (MMN) evoked response was investigated in 20 normal-hearing adult females. Perceptible and imperceptible frequency contrasts were employed in an oddball paradigm. The perceptible contrast consisted of an 1122Hz standard and a 1000Hz target, while the imperceptible contrast consisted of an 1122Hz standard and an 1120Hz target. Data were referenced separately to the tip of the nose, the ipsilateral mastoid, and the mathematical average of the two mastoids. Presence of a response was determined according to strict criteria established a priori. The correspondence between MMN findings and parallel behavioral discrimination data was not systematic. Inverting electrode had an effect of MMN presence. MMNs were more likely to be present for mastoid-referenced data than nose-referenced data. Thus, when using the current paradigm, a mastoid reference is suggested to optimize the detection of the MMN response.

AB Chronic and acute smoking effects on the auditory middle latency response (AMLR) were studied in older (55-81 years) and younger (19-30 years) normal-hearing listeners. Forty healthy participants were selected for one of four groups: older smokers, older nonsmokers, younger smokers, or younger nonsmokers. Biochemical urine analyses confirmed participant categorization as smoker or nonsmoker. Click-evoked AMLRs were acquired once from nonsmokers and twice (chronic condition, acute condition) from smokers. Waveform latency (V, Na, Pa) and relative amplitude (V-Na, Na-Pa) were examined with two independent variables (age, smoking) using MANOVA. Results (n=40) revealed no chronic effect of smoking in the AMLR from smokers compared to nonsmokers. However, in both older and younger smokers (n=20), Na-Pa amplitude was significantly larger in the acute compared to the chronic smoking condition, indicating an acute smoking effect. There was no interaction of smoking and aging. This is a first study describing long-term, chronic and acute smoking effects on AMLRs in older compared to younger listeners. Results suggest that cigarette smoking is an important variable for AMLR research and clinical practice.

AB The goal of the present study was to compare six transposing signal-processing algorithms based on different principles (Fourier-based and modulation based), and to choose the algorithm that best enables identification of environmental sounds, i.e. improves the ability to monitor events in the surroundings. Ten children (12-15 years) and 10 adults (21-33 years) with normal hearing listened to 45 representative environmental (events) sounds processed using the six algorithms, and identified them in three different listening experiments involving an increasing degree of experience. The sounds were selected based on their importance for normal hearing and deaf-blind subjects. Results showed that the algorithm based on transposition of 1/3 octaves (fixed frequencies) with large bandwidth was better (p0.015) than algorithms based on modulation. There was also a significant effect of experience (p0.001). Adults were significantly (p0.05) better than children for two algorithms. No clear gender difference was observed. It is concluded that the algorithm based on transposition with large bandwidth and fixed frequencies is the most promising for development of hearing aids to monitor environmental sounds.

TI Discrimination of envelope statistics reveals evidence of sub-clinical
   hearing damage in a noise-exposed population with 'normal' hearing
   thresholds

AB Noise exposure can affect the functioning of inner hair cells (IHC) within the cochlea, leading to a 'noisy' representation of the properties of sounds even when absolute thresholds are normal. This may lead to a reduced ability to discriminate sounds based on their statistical properties, especially for narrowband sounds presented at low levels, since such sounds excite only a small proportion of the IHCs. This idea was tested by requiring subjects to discriminate a Gaussian noise from a 'low-noise noise' with minimal envelope fluctuations. The noises were centred at 2, 3, or 4kHz. The stimulus duration required for threshold was measured as a function of sensation level (SL) for two groups of normal-hearing subjects, one rarely exposed to high-noise events (control group, C) and one frequently exposed to high-noise events (experimental group, X). For group X, threshold consistently rose for SLs below about 20dB, while for group C the threshold did not consistently rise at low SLs (although it did for a minority of subjects). The worsening in performance with decreasing level was significantly greater for group X than for group C.

AB The purpose of this study was to examine if a pre-determined exposure level and duration of MP3 player music would result in significant changes in cochlear function when measured with audiometric and physiological methods. Distortion-product otoacoustic emissions (DPOAEs), synchronized spontaneous otoacoustic emissions (SSOAEs), and hearing thresholds were measured in 20 normal-hearing adults before and after a 30-minute MP3 player music exposure. DPOAEs were acquired with 65/45 dB SPL primary tones (f2=0.842-7.996 kHz) with a frequency resolution of 8 points/octave. A probe microphone system recorded ear-canal music levels and was used to equalize levels at approximately 85 dBC across individuals during the music presentation. Comparison of pre- and post-exposure measurements revealed no significant differences in hearing thresholds, but DPOAE levels in half-octave bands centered from 1.4-6.0 kHz were significantly reduced following the music exposure. Post-exposure shifts in SSOAE frequency and level were highly variable in individuals identified with SSOAEs. The results for the exposure conditions explored in this study indicate that changes in otoacoustic emissions may precede the development of music-induced hearing threshold shifts.

AB One limitation with the Bone Anchored Hearing Aid (Baha) is too poor amplification for patients with moderate to severe sensorineural hearing losses. Therefore, we investigated if bone conducted (BC) sound transmission improves when the stimulation approaches the cochlea. Also the influence from the squamosal suture on BC sound transmission was investigated. Both sides of the heads on seven human cadavers were used and vibrational stimulation was applied at eight positions on each side with a frequency range of 0.1-10 kHz. A laser Doppler vibrometer was used to measure the resulting velocity of the cochlear promontory. It was found that the velocity of the promontory increases as the stimulation position approaches the cochlea; this was especially apparent at distances within 2.5 cm from the ear canal opening and when the stimulation position was in the opened mastoid. At frequencies above 500 Hz there was on average 10 to 20 dB greater vibrational response at the cochlea when the stimulation was close to the cochlea compared with the normal Baha position. Moreover, even if there were general indications of attenuation of BC sound when passing the squamosal suture, an effect from the suture could not be conclusively determined.

AB In this study we investigated the effects of amalgam dental fillings on auditory thresholds. Participants (n=39) were non-smoking women age 40 to 45. Regression and correlation analyses were performed between auditory thresholds, measured from 0.25 to 16 kHz, and the number/surface area of dental fillings, using the ASHA criteria for ototoxic change as a reference for comparison. No significant correlation (p0.05) was found between composite (non-amalgam) filling or drilling data and auditory thresholds. However, there was a significant positive linear correlation between amalgam filling data and auditory thresholds at 8, 11.2, 12.5, 14, and 16 kHz. The strongest association (r=0.587, n=39, p.001, r2=0.345) was at 14 kHz, where each additional amalgam filling was associated with a 2.4 dB decline in hearing threshold (95% confidence interval [CI], 1.3-3.5 dB). The results suggest an association between more amalgam fillings and poorer thresholds at higher frequencies, which could contribute to presbyacusis in developed countries. This provides further argument for the use of amalgams to be phased out where suitable alternatives exist.

AB This paper summarizes twenty studies, published since 1989, that have measured experimentally the relationship between speech recognition in noise and some aspect of cognition, using statistical techniques such as correlation or factor analysis. The results demonstrate that there is a link, but it is secondary to the predictive effects of hearing loss, and it is somewhat mixed across study. No one cognitive test always gave a significant result, but measures of working memory (especially reading span) were mostly effective, whereas measures of general ability, such as IQ, were mostly ineffective. Some of the studies included aided listening, and two reported the benefits from aided listening: again mixed results were found, and in some circumstances cognition was a useful predictor of hearing-aid benefit.

AB We focus this theoretical paper on a neglected distinction in tinnitus research between moderators and mediators of tinnitus distress. A moderator variable is one that influences the strength of a relationship between two other variables. In the paper we propose that several variables might act as moderators of tinnitus distress. Degree of hearing loss, arousal, insomnia, characteristics of tinnitus, noise sensitivity, and a range of psychological factors such as personality and perceived control are discussed as potential moderators. We then move on to mediator variables. A mediator variable is one that explains the relationship between the two other variables, and must by definition be caused by a predictor, and then mediate between the predictor and the dependent variable. We propose that stress levels (caused by tinnitus), classical conditioning, selective attention towards tinnitus, and psychological acceptance of tinnitus (versus experiential avoidance) might be mediators of distress. We encourage more research on moderators and mediators of tinnitus distress, as these will help illuminate treatment protocols and how they might work.

AB A conceptual framework for human communication, based on traditional biological ecology, is further developed. The difference between communication at the message and behavioural levels is emphasized. Empirical data are presented from various studies, showing that degree of satisfaction with communication is correlated with how close the outcome is to the memory of function prior to hearing impairment. We found no indication that hearing-impaired subjects overestimated their previous hearing or the hearing of normal-hearing people. Satisfaction was also correlated with the outcome and degree of fulfilment of expectations. It did not correlate with improvement of function. The concept of balance was presented and tested using a semi-quantitative approach. Several projects were presented in which the framework was applied: the hearing impaired as counsellor, choosing sides in unilateral deafness, a monitoring device for the deafblind, interaction between Swedish as a second language and hearing impairment, language development in hearing impaired children. By regarding hearing as a component of a communicative system, the perspective of audiological analysis and rehabilitation is broadened.

AB In a single study, silent speechreading and signed language processing were investigated using fMRI. Deaf native signers of British sign language (BSL) who were also proficient speechreaders of English were the focus of the research. Separate analyses contrasted different aspects of the data. In the first place, we found that the left superior temporal cortex, including auditory regions, was strongly activated in the brains of deaf compared with hearing participants when processing silently spoken (speechread) word lists. In the second place, we found that within the signed language, cortical activation patterns reflected the presence and type of mouth action that accompanied the manual sign. Signed items that incorporated oral as well as manual actions were distinguished from signs using only manual actions. Signs that used speechlike oral actions could be differentiated from those that did not. Thus, whether in speechreading or in sign language processing, speechlike mouth actions differentially activated regions of the superior temporal lobe that are accounted auditory association cortex in hearing people. One inference is that oral actions that are speechlike may have preferential access to 'auditory speech' parts of the left superior temporal cortex in deaf people. This could occur not only when deaf people were reading speech, but also when they were processing a signed language. For the deaf child, it is likely that observation of speech helps to construct and to constrain the parameters of spoken language acquisition. This has implications for programmes of intervention and therapy for cochlear implantation.

AB Mozambique is a developing African country recuperating from a lengthy civil war. As a result, documenting the incidence of hearing loss has remained a low priority. This paper provides results from work being carried out by the Mozambique Audiology Program (MAP), which is a philanthropic effort established in 1997 to introduce audiology services and identify auditory disorders in the country. Some decades before the MAP, another program reported extremely high incidence rates of otitis media in 1000 primary school students in the capital city of Maputo. This paper presents the MAP results from mass hearing screenings conducted over a two year period on a cohort group of 2685 students ranging in age from 3-18 years at a preschool and primary school in Chicuque and Maxixe, Mozambique. This current study showed a prevalence of 5% of the total 2685 students across ages with varying degrees of hearing loss resulting from multiple etiologies. External auditory canal obstruction was the greatest otoscopic abnormality (regardless of age), followed by severely limited tympanic membrane mobility (i.e. flat tympanogram) in the absence of EAC obstruction in those students identified with hearing loss. Of the 145 student identified with hearing loss, there were 27 found to have active drainage. Some of the benefits of conducting mass hearing screening in this population are discussed.

DE Deafblindness; Ontological security; Social recognition
ID USHER-SYNDROME; VISUAL IMPAIRMENT; ILLNESS; MODEL
AB Trust, ontological security, and social recognition are discussed in relation to self-identity among people with acquired deafblindness. To date the phenomenon has not been elaborated in the context of deafblindness. When a person with deafblindness interacts with the social and material environment, the reliability, constancy, and predictability of his or her relations is crucial for maintaining or achieving ontological security or a general and fairly persistent feeling of well-being. When these relations fundamentally change, the impact on ontological security will be very negative. The construction of social recognition through the interaction between the self and others is embodied across three dimensions: at the individual level, at the legal systems level, and at the normative or value level. The relationship between trust and ontological security on the one hand and social recognition on the other hand is discussed. It is argued that these basic processes affecting personality development have to be identified and acknowledged in the interactions people with deafblindness experience. Some implications for the rehabilitation of people with acquired deafblindness are presented and illustrated.

AB The objective of this study was to document the development of speech, language, and reading skills between primary and secondary school ages in children who received cochlear implants during preschool years. Subjects were a sample of 85 North American adolescents recruited from a larger sample of 181 participants from a previous investigation. Students were first tested in early elementary school (ages eight to nine years) and were re-evaluated in high school (ages 15-18 years) for this study. The methods used were: performance on a battery of speech perception, language, and reading tests. These were compared at both test ages and significant predictors of outcome level identified through multiple regression analysis. Speech perception scores improved significantly with long-term cochlear implant use. Average language scores improved at a faster than normal rate, but reading scores did not quite keep pace with normal development. Performance in high school was most highly correlated with scores obtained in elementary grades. In addition, better outcomes were associated with lower PTA cochlear implant threshold, younger age at implantation and higher nonverbal IQ. In conclusion, early cochlear implantation had a long-term positive impact on auditory and verbal development, but did not result in age-appropriate reading levels in high school for the majority of students.

AB Wideband reflectance (WBR) is a method of middle-ear analysis that may provide more information and provide a more detailed look at the middle-ear system than tympanometry. WBR has the potential to improve efficiency of newborn hearing screening programs by reducing time needed to accurately diagnose middle-ear status. This prospective study compares wideband reflectance results with 226-Hz and 1000-Hz tympanometry and distortion product otoacoustic emissions in a group of infants and children with cleft lip and palate, who have not been treated with myringotomy or tubes. Results are also compared to normative data in children of similar ages using the same instrument and methods. Results demonstrate that wideband reflectance showed the highest level of agreement (88%) with DPOAE results.

AB This study sought to determine the level of speech intelligibility, narrative abilities, and their interrelationship in 18 Finnish children implanted at the average age of three years, four months. Additionally, background factors associated with speech intelligibility and storytelling ability were examined. Speech intelligibility was examined by means of an item identification task with five listeners per child. Three and five years after activation of the implant, the children reached average intelligibility scores of 53% and 81%, respectively. The story generation abilities of the implanted children exceeded their hearing age by one year, on average. This was found after comparing their results with those of normally-hearing two- to six-year-olds (N = 49). According to multiple regression analysis, comorbidity (number of additional needs), chronological age, and/or age at activation usually explained from 46% to 70% of the variation in speech intelligibility and narrative abilities. After controlling for age, communication mode, and number of additional needs, speech intelligibility and ability to narrate were statistically significantly associated with each other three years after activation, but not anymore five years after activation.

AB Within the International Classification of Functioning, Disability, and Health (ICF; WHO), participation in work is acknowledged as one of the major areas in life (D8). Difficulties that make it impossible for the person to optimally partake in work result in participation restriction. An increasing number of people with hearing loss are seeking help for occupational problems. Various studies identified issues that should be addressed in the management of employees with hearing loss and emphasized the importance of a tailored vocational enablement program. This paper describes a recently developed vocational enablement protocol (VEP) addressing the specific needs of those with hearing loss in the workforce. It is characterized by an integrated approach (occupational physician, otolaryngologist, audiologist, social worker/psychologist, speech-language pathologist). The goal is to facilitate participation in, and retention of, work. The protocol is currently implemented in a few audiological centers in the Netherlands. This paper presents data collected at the audiological center of the VU University Medical Center, Amsterdam. Thus far, 86 patients, aged 19 to 64 years (mean 48, SD 23), have completed the protocol. Experiences with the procedure are described, and recommendations for future practice and research are discussed.

AB The objective of the investigation is to study the interference of different background noises on speech processing. For this purpose speech recognition with the Hagerman test and a test battery with speech comprehension tasks (SVIPS) were performed in speech-weighted background noises varying in temporal structure, signal-to-noise ratio (SNR), and meaningfulness. With different test criteria and a score of perceived effort, the aim was to get a more complete picture of speech comprehension under adverse listening situations. Twenty-four subjects, aged 56-83 years, with a bilateral sensorineural hearing impairment, participated in the study. Differences in performance between the different background noises varied depending on the speech processing task, SNR, and on quantitative versus qualitative outcome measures. Age effects were seen in the Hagerman test and especially in background conditions of modulated noises (speech and reversed speech). Findings are discussed in relation to a hypothesis suggesting that masking and distraction interference from background noises on speech processing at peripheral, central auditory, and cognitive levels depends on the SNR used and the noise type and the listening task.

AB The purpose of the present article is to present an overview of a set of studies conducted in our own laboratory on cognitive and communicative development in children with cochlear implants (CI). The results demonstrate that children with CIs perform at significantly lower levels on the majority of the cognitive tasks. The exceptions to this trend are tasks with relatively lower demands on phonological processing. A fairly high proportion of the children can reach a level of reading comprehension that matches hearing children, despite the fact that they have relatively poor phonological skills. General working memory capacity is further correlated with the type of questions asked in a referential communication task. The results are discussed with respect to issues related to education and rehabilitation.

AB The mismatch negativity (MMN) is an electric brain response which is automatically elicited by any discriminable change in a repetitive sound or sound pattern. When this change is made smaller in magnitude, the MMN is attenuated in amplitude, eventually vanishing at around the discrimination threshold. Therefore the MMN provides a unique objective index for a subject or patient's discrimination accuracy. Furthermore, with the MMN, these discrimination thresholds can be separately determined for all the different auditory attributes. Moreover, the individual's ability to discriminate complex sound stimuli and patterns such as different phonemes can also be measured by using the MMN.

AB Sub-Saharan Africa not only has the highest rates of neonatal, infant, and child mortality worldwide but also accounts for a significant proportion of the global burden of permanent congenital and early-onset hearing loss (PCEHL). This article explores the diverse psychosocial, educational, and economic consequences of PCEHL in the region and highlights the interrelationships between this condition and the crucial domains of early childhood development. It also examines relevant levels of prevention and current practices within the context of the birthing patterns and routine immunization schedules in the first three months of life. It presents practical options for addressing the needs of children with PCEHL and their parents against the backdrop of the prevailing health and socioeconomic conditions. It concludes by underscoring the crucial dimensions of culturally-sensitive interventions as well as the need for ear-care professionals in each country to take advantage of the growing global initiatives for hearing impairment prevention within a multidisciplinary framework to advance the best interests of the affected children and their families.

AB Older adults often have more difficulty listening in challenging environments than their younger adult counterparts. On the one hand, auditory aging can exacerbate and/or masquerade as cognitive difficulties when auditory processing is stressed in challenging listening situations. On the other hand, an older listener can overcome some auditory processing difficulties by deploying compensatory cognitive processing, especially when there is supportive context. Supportive context may be provided by redundant cues in the external signal(s) and/or by internally stored knowledge about structures that are functionally significant in communication. It seems that listeners may achieve correct word identification in various ways depending on the challenges and supports available in complex auditory scenes. We will review evidence suggesting that older adults benefit as much or more than younger adults from supportive context at multiple levels where expectations or constraints may be related to redundancies in semantic, syntactic, lexical, phonological, or other sub-phonemic cues in the signal, and/or to expert knowledge of structures at these levels.

AB A general working memory system for ease of language understanding (ELU, Ronnberg, 2003a) is presented. The purpose of the system is to describe and predict the dynamic interplay between explicit and implicit cognitive functions, especially in conditions of poorly perceived or poorly specified linguistic signals. In relation to speech understanding, the system based on (1) the quality and precision of phonological representations in long-term memory, (2) phonologically mediated lexical access speed, and (3) explicit, storage, and processing resources. If there is a mismatch between phonological information extracted from the speech signal and the phonological information represented in long-term memory, the system is assumed to produce a mismatch signal that invokes explicit processing resources. In the present paper, we focus on four aspects of the model which have led to the current, updated version: the language generality assumption; the mismatch assumption; chronological age; and the episodic buffer function of rapid, automatic multimodal binding of phonology (RAMBPHO). We evaluate the language generality assumption in relation to sign language and speech, and the mismatch assumption in relation to signal processing in hearing aids. Further, we discuss the effects of chronological age and the implications of RAMBPHO.

AB Rudner et al (2008) showed that when compression release settings are manipulated in the hearing instruments of Swedish habitual users, the resulting mismatch between the phonological form of the input speech signal and representations stored in long-term memory leads to greater engagement of explicit cognitive processing under taxing listening conditions. The mismatch effect is manifest in significant correlations between performance on cognitive tests and aided-speech-recognition performance in modulated noise and/or with fast compression release settings. This effect is predicted by the ELU model (Ronnberg et al, 2008). In order to test whether the mismatch effect can be generalized across languages, we examined two sets of aided speech recognition data collected from a Danish population where two cognitive tests, reading span and letter monitoring, had been administered. A reanalysis of all three datasets, including 102 participants, demonstrated the mismatch effect. These findings suggest that the effect of phonological mismatch, as predicted by the ELU model (Ronnberg et al, this issue) and tapped by the reading span test, is a stable phenomenon across these two Scandinavian languages.

AB It is well known that two patients suffering from a sensorineural hearing loss with similar audiograms can benefit significantly differently from amplified hearing even if the same settings of the hearing aids are used. The origin of this problem is complex but one part can be caused by the diagnosis itself; all inner-ear hearing losses are assumed similar. Such hypothesis is a simplification that probably leads to suboptimal hearing-aid fitting. For a better understanding of the signal degeneration caused by a cochlear lesion a model layout of the signal transmission in the peripheral hearing organ is presented. This model differentiates between processes in the inner ear caused by the outer hair cells, the inner hair cells, and the endocochlear potential driving the system. The model is intended to predict alteration of the signal caused by different types of cochlear lesions. Ultimately, the model may lead to improved hearing aids and fittings.

AB Since little information is available on the outcome of early hearing intervention programs in South Africa, this article examines data on infants and families registered with a family-centred, home-based intervention program (HI HOPES) over a 12-month period in order to track the effectiveness of the holistic unbiased support to families of infants and toddlers with a hearing-loss. The aim of HI HOPES, which is based on the SKI-HI model of early intervention in the USA, is to ensure that families are enabled to make informed choices for their unique infant. Data were gathered on 32 infants ages birth to three years and their families using both qualitative and quantitive measures which included analysis of demographic data, quarterly language assessments, and parent satisfaction surveys. The report on the pilot year of this early intervention program shows that, though the sample is small, there is significant improvement in infant receptive and expressive language for infants identified before seven months of age, as well as a high level of satisfaction from families who have received services.

   who have opened their homes to us as we come alongside them to inform
   and empower them on this journey. Thanks to all our early
   interventionists who go into homes weekly, to support and inform
   parents. A special thank you to our researcher Jenni Calvert-Evers who
   worked on the data throughout our first year, and to the HI HOPES team
   (especially Carla Zille and Kelly Naude) for assisting in getting the
   data updated and processed. A final thanks to our resident

AB Verifying the match to prescribed electro-acoustic performance is essential in a scientific approach to pediatric hearing instrument fittings. This study aimed to compare hearing instrument output values, at 65 and 90dB sound-pressure level (SPL) input signals, of instruments fitted to pre-school children in South Africa to the targets prescribed by the DSLm [i/o] (version 5.0) across the frequency range. Outputs of 31 BTE hearing instruments (20 children, 3--6 years) were verified using coupler-based SPL measurements and measured real-ear-to-coupler differences (RECDs). Results revealed that most of the hearing instrument fittings (regardless of the degree of hearing loss) did not match the prescribed targets. Only 25% of the fittings matched three or more output targets at 65 dB SPL input signal. Output values at 90 dB SPL input signal were far below the prescribed targets. It can be concluded that the lack of a systematic evidence-based approach might lead to inconsistent hearing instrument fittings. Findings may be used to educate clinicians to ensure optimal pediatric hearing instrument fittings.

AB Children with hearing loss who happen to reside in Africa deserve the chance to develop according to their potential as much as their peers living in more affluent regions. This leaves a moral obligation to pursue ways of initiating, developing,and growing early hearing detection and intervention services in Africa. For these reasons, the first EHDI Africa international conference was held in Johannesburg, South Africa, in 2007 (13-14 August). The theme was 'Building bridges in Africa: Early childhood development for children with hearing loss'. This special issue contains several reports from the EHDI Africa conference.

AB Parental knowledge and attitudes regarding infant hearing loss are crucial to the successful implementation of EHDI programs, especially in developing countries where concerns have been raised of cultural-based ignorance and resistance towards childhood disabilities. This study investigated maternal knowledge and attitudes amongst 100 South African mothers accessing the public healthcare system using a face-to-face survey. The questionnaire (16 items) probed knowledge of infant hearing loss, superstitious cultural beliefs, and attitude towards early detection and intervention for hearing loss. Results indicate that more than 50% of the sample correctly identified three common etiological factors (ear discharge, medication, congenital) for infant hearing loss. At least one superstitious cultural belief regarding a possible cause of hearing loss was held by 57%. Maternal attitude was overwhelmingly positive with 99% indicating the desire to have their baby's hearing screened after birth and a high acceptance of hearing aids. The study demonstrates a need for increased maternal awareness regarding infant hearing loss but also a readiness for implementation of EHDI programs.

AB The purpose of this study was to examine the current status of newborn/infant hearing screening programs in public sector hospitals in South Africa by means of a descriptive survey. Data was gathered using a self-administered postal questionnaire, which included questions on screening resources and protocols, follow-up, diagnostic, and information management procedures as well as timing of intervention. The questionnaire was sent to 86 speech therapy and audiology departments within public sector hospitals throughout South Africa and 44 questionnaires were returned. The findings indicated that 27% (n = 12) of respondents were conducting some form of hearing screening. The most frequently reported reasons for the absence of a screening program were a lack of appropriate equipment and a shortage of staff. Institutions with active screening programs face many challenges and programs are mostly unsystematic. Reported findings make a valuable contribution to the field of early hearing detection and intervention by providing a baseline for the development and structuring of early hearing detection and intervention services as a priority in the public healthcare sector of South Africa.

AB This investigation examined how age and test condition affect one's ability to comprehend discourse passages, and determined whether age and test condition affect discourse comprehension and closed-set sentence recognition in a similar way. Young and older adults were tested with closed-set sentences from the newly-created build-a-sentence test (BAS) and a series of discourse passages in two audiovisual conditions: favorable, where the talker's head was clearly visible and the signal-to-babble ratio (SBR) was more optimal; and unfavorable, where the contrast sensitivity of the visual signal was reduced and the SBR was less optimal. The older participants recognized fewer words in the BAS than the young participants in both test conditions. Degrading the viewing and listening conditions led to a greater decline in their performance than in the young participants' performance. The older participants also did not perform as well at comprehending spoken discourse in the two test conditions. However, unlike the results from the BAS, the age difference for discourse comprehension was not exacerbated by unfavorable conditions. When attempting to comprehend discourse, older adults may draw upon verbal and cognitive abilities that are relatively insensitive to age.

ID CHILDREN; IDENTIFICATION
AB Hearing loss is referred to as the silent, overlooked epidemic in developing countries, and data reporting the mean age of diagnosis and intervention is virtually non-existent due to limited systematic or routine screening programs. The objective of this paper is to present findings of recent practice in early diagnosis and intervention services in an urban South African context, with specific reference to parental needs for support. Data was collected by means of questionnaire surveys for 54 parents of children with congenital or early-onset hearing loss, followed by focus group discussions conducted with 10 parents. The results of this study indicate the mean age of diagnosis to be 23 months (+/- 18 SD), the mean age of initial hearing-aid fitting to be 28 months (+/- 19 SD), and the mean age of enrollment into an early intervention program to be 31 months (+/- 19 SD). In addition, results signify that this diverse and challenging population of parents of young hearing-impaired children largely depends on the ongoing support, guidance, and commitment of the pediatric audiologist.

AB The purpose of this study was to examine the effect of acceptance versus suppression of disruptions on a mental imagery task in a sample of tinnitus patients. Previous research has indicated that acceptance can be an effective strategy for dealing with unpleasant experiences such as pain and anxiety. The study used a between-group design, including 47 participants who completed a task involving mental imagery in a sound-proof booth. Participants were randomly assigned to three instruction conditions: acceptance, suppression, or a control condition. The results showed a significant difference between the acceptance group and the control group in that participants in the acceptance group were able to focus on the imagery task for a longer time without being interrupted. The study provides preliminary support for the notion that acceptance can be a helpful strategy for tinnitus patients.

ID IDENTIFICATION
AB Though the health and economic issues in developing countries may create situations in which the development of early hearing detection and intervention (EHDI) programs could seem insurmountable, developing countries have some resources that are not easily available to those in the developed world. Developing countries often have well-organized communities in which members work together for the benefit of the individuals within their communities as well as a willingness to learn strategies that can improve the lives of individuals in their communities. Paradoxically, there also exists societal intolerance for disabilities that can result in stigmatization and ultimate isolation of affected families. Hopefully, education within these communities can begin to overcome historical intolerance. While some might argue that sufficient financial resources are the key to the development of an EHDI system, the Colorado system, although grateful for all financial resources, is dependent, first and foremost upon the human resources. This article provides information about the history of the Colorado system in the hopes that lessons learned will provide valuable input to others facing similar challenges.

AB The purpose or this study is to develop and evaluate disyllabic Mandarin speech test materials (MSTMs) in order to facilitate wider use of speech audiometry in Chinese audiology clinics. Phonologically balanced Manclarin disyllabic materials with high familiarity were designed based on the basic rules for developing speech materials and the particular characteristics of Mandarin, and recorded digitally. In order to establish the validity and reliability of these Mandarin disyllabic materials, equivalence of difficulty between the word lists was evaluated for a group of 60 subjects (age-range 18 25 years) with normal hearing. Subsequently, performance-intensity (PI) functions were measured in a group of 30 subjects with normal hearing (age-range 18 25 years), and a group of 35 subjects with sensineural hearing loss. The nine lists of Mandarin disyllabic materials were found to have sufficient reliability and validity to be used in clinical situations.

ID THRESHOLD LEVELS; NOISE; WORKERS; SWEDEN
AB The objective of this study was to estimate the prevalence of hearing impairment in a representative adult population in southern Taiwan and compare the results to those of similar studies in other countries. A stratified systematic cluster sample of 1140 residents, aged >= 20 years, of Tainan City was studied from 2001 to 2003. The test battery included otoscopy, pure-tone audiometry, and a questionnaire covering relevant personal, occupational, and family history. The hearing threshold level (HTL) was defined as the better ear pure-tone average (BPTA) (i.e. the average of hearing thresholds at frequencies 500, 1000, 2000, and 4000 Hz). The prevalence of hearing impairment was 21.4% (95% confidence interval: 19.3 - 23.7%) at BPTA >= 25 dB HTL. Middle ear disease was a significant risk factor for hearing impairment in addition to age and gender. The overall prevalence of hearing impairment may be higher in Taiwan (17.1%) than in western populations (11.5%), but differences in the definition of hearing impairment severity and variation in sex distribution among studies may account for this higher prevalence.

AB The purpose of this study was to estimate the prevalence and severity of presbycusis in older Chinese people in Taipei, Taiwan. Pure-tone audiometry and a questionnaire were administered to a randomly-recruited cohort of people > 65 years old (n=1221) from a community in Taipei. The study cohort showed pure-tone thresholds worsening, especially at frequencies > 2 kHz, with increasing age. The mean pure-tone average at speech frequencies (0.5, 1, and 2 kHz) of the better ear of subjects stratified by five-year age groups ranged from 34.9 dB hearing level (HL) to 46.4 dB HL. The pure-tone average at speech frequency in women was slightly higher than that in men in all age groups. The prevalence of presbycusis (M3 >= 55 dBHL) was 1.6% (65 - 69 years), 3.2% (70 - 74 years), 7.5% (75 - 79 years), and 14.9% (>= 80 years). Persistent tinnitus was present in 13.9% of subjects, and 18.8% of subjects had a history of vertigo. Of subjects with a clinically evident hearing impairment (M3 >= 55 dBHL), 18.4% used hearing aids. These data provide estimates of the prevalence and severity of presbycusis in community-dwelling older persons in Taiwan.

ID MENIERES-DISEASE
AB Hearing losses are frequently described by categories that characterize the configuration, severity, and site of lesion from a pure-tone audiogram. Although many category descriptors are in common use, there are no standard definitions of those terms, nor have the category definitions been validated against current clinical practice. The development and validation of AMCLASS (TM) is described. To validate the classification method, five expert judges selected configuration, severity, and site of lesion categories for 231 audiograms that varied widely in audiometric configuration. Interjudge comparisons indicated that expert judges frequently disagree on how they describe an audiogram. Category definitions were adjusted to maximize agreement between AMCLASS (TM) and the consensus of the judges. The final set of category definitions produced categories that agreed with the consensus more often than the average agreement between pairs of judges.

This paper describes the development of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA), which was constructed in accordance with published recommendations for self-efficacy questionnaire development. The psychometric properties of the MARS-HA were evaluated with new and experienced hearing-aid users. The results revealed strong internal consistency and good testretest reliability in both groups, with the following subscales identified both for the new users and the experienced users: (1) basic handling, (2) advanced handling, (3) adjustment to hearing aids, and (4) aided listening skills. validity was established through the examination of expected differences based on group comparisons, training effects, and the impact of particular hearing aid features. The MARS-HA is a reliable and valid measure of hearing-aid self-efficacy and can be used to assist clinicians in identifying areas of low confidence that require additional audiologic training.

AB The purpose of the present study was to examine the relative contribution of genetic and environmental effects on the air-conducted hearing threshold levels at low (0.125 - 0.5 kHz), mid (1 - 2 kHz), and high (4 - 8 kHz) frequencies separately for the better and worse hearing car in older women. We also examined the distribution of audiogram configurations. Data was analysed using quantitative genetic modelling. As part of the Finnish twin study on aging (FITSA), hearing was measured in 103 monozygotic and 114 dizygotic female twin pairs aged 63 - 76 years. Approximately every third subject had a flat type, and two-thirds a descending type of audiogram configuration. No significant difference was observed in the distribution of audiogram configurations between zygosity groups. In the better ear, additive genetic effects accounted for 64% - 74% of the total variance at different frequencies. For the worse ear, environmental effects were larger. Although overall heritability is rather constant across the frequency spectrum, it is noteworthy that at low and high frequencies frequency-specific genetic and environmental effects together accounted for the majority of the total variance.

ID RELIABILITY; POPULATION
AB The SCAN-C is a test for auditory processing disorders in children developed in the USA. There are concerns that the SCAN-C may over-diagnose auditory processing disorders in UK children. There are also questions concerning the impact of language level and interpretation of SCAN-C results. SCAN-C results from 99 Oxfordshire school children aged 6 to 10 were compared to US-based normative data. Across all age bands, the UK sample scored significantly worse on two subtests: the filtered words (FW) and auditory figure-ground (AFG) sections as well as on the composite score. Differences in performance were largely due to accent effects. Applying US norms to UK children's performance results in a high rate of over-identification of listening difficulties. However, we show that US norms can be used provided SCAN-C scores for children in the UK are adjusted by adding a constant. Using factor analysis, SCAN-C subtests mapped onto two factors; FW and AFG onto a 'monaural low-redundancy degradation' factor, and CW and CS onto a 'binaural separation/competition' factor. Implications for use of the SCAN-C with UK children are discussed.

AB Transient-evoked otoacoustic emissions (TEOAEs) were recorded from more than 30000 newborns over a six year period. Analysis was performed on all the TEOAEs that passed the bedside universal hearing screen (n = 60431), in order to characterize the normal properties of neonatal TEOAEs and to study ear and sex effects. Short recording times (median = 33 s) were observed in combination with high entire TEOAE level (median = 18.8 dB SPL for an 81.8 dB SPL peak stimulus), and high reproducibility (median = 86%). Signal-to-noise ratio (S/N) of the TEOAE was highly frequency-dependent, being poorer at low frequencies. Prolonged averaging increased median reproducibility to 97%, but the minor S/N-improvement at low frequencies did not justify the longer test time. Highly significant mean lateral asymmetries (right > left) and sex differences (female > male) existed in entire TEOAE level, S/N TEOAE, and in half-octave frequency bands (700-4000 Hz). Mean lateral and sex entire TEOAE level differences were 1.1 dB and 1.3 dB, respectively. Stimulus levels were not affected by ear or sex. Hence, physiological differences at the level of organ of Corti were demonstrated in newborns.

ID PREVALENCE
AB We performed a retrospective analysis of TEOAEs from 1415 neonatal ears to investigate whether the application of linear averaging techniques may provide greater screening specificity than conventional nonlinear averaging techniques. Pass criteria were based on correlations between replicate averages, and pass rates were compared between linear and nonlinear averaging techniques. The linear averaging technique gave a higher pass rate as hypothesized, so that 35% of ears that passed using the linear method failed using the nonlinear method. In addition, lack of saturation was more evident for the short-latency components of the TEOAE. These results, from a large sample of recordings obtained under field conditions, indicate that there is potential to improve specificity of neonatal TEOAE screening using linear averaging techniques. A combination of linear and nonlinear techniques for the long and short latency components of the TEOAE, respectively, may offer further advantages.

AB This study analyses results from the first Swedish UNHS program. It includes over 33000 measurement Files from 14287 children at two maternity wards. The screening program uses a two-stage TEOAE test procedure. A database was created in MedLog after data transformation in Word and Excel. The coverage rate was 99.1%. Bilateral pass rate after retesting was 97.0%. A unilateral pass criterion would have resulted in 1268 fewer children (9.0% of target group) for retesting and 231 fewer children (1.6% of target group) for diagnostic evaluation. When the first test was performed on the day the child was born, the pass rate was 64.8%; the pass rate increased to 89.2% when testing >= 3 days after birth. High coverage rates and pass rates were found to be possible, independent of the number of children born at the maternity ward. Learning curves were observed in the program with improvements distributed over time. Test performance was clearly better when the children were tested day two after birth or later.

AB The mode of stimulation employed in newborn screening of the auditory brainstem response has evolved from the clinically standardized supraaural earphone to the tubal insert earphone, to most recently a circumaural earphone developed for this test. Considered here is the need to develop a standard for calibration of such devices for newborn screening applications, in particular. At risk is the prospect of missing the milder degrees of hearing loss, assuming a goal of detecting all clinically-significant congenital hearing losses. Two commercially manufactured test instruments for automated newborn screening were scrutinized via bench testing of sound output from their respective transducers, using a variety of measurements. By convention or design, none of the measurement approaches involved a model of the newborn car, per se. While it was concluded that the manufacturers' method shows Promise, namely as a relatively simple and potentially reliable method of calibration, concerns arose regarding output levels when measured according to both the manufacturers' and the authors' methods. Further work is needed to critically assess calibration methods and to establish, to the extent possible, appropriate norms and validation studies in newborns to provide a better understanding of the actual sound pressure level of the screening stimulus.

AB Reported are the results of meta-analyses of data derived collectively from a sample of 56 published research studies on electric response audiometry (ERA) using auditory steady-state responses (ASSRs). Several specific methodological issues were examined and hypotheses were posited to rigorously test common conclusions drawn from the ASSR literature on the accuracy of ASSR-ERA. Explanatory variables for analyses were type of population (normally hearing and hearing-impaired), type of modulation, number of sweeps acquired during response analysis, electrode montage, and modulation rate (80 vs. 40 Hz). No explanatory variables were found to be significantly related to the degree of disparity between thresholds obtained by ASSR-ERA versus behavioral audiometry in the normally hearing population. Conversely, all but one explanatory variable (i.e. electrode montage) was found to be significantly related to mean threshold differences in the hearing-impaired and combined populations. Results both substantiate some of common conclusions drawn from the literature but call others into question, helping to identify those methodological issues which appear to, or not to, significantly affect the accuracy of estimating threshold using ASSR measurement. In addition to these Findings, another practical outcome of this study was the development of various summary tables of the data analysed from the literature sampled.

AB This study aimed to compare the high frequency (1 kHz) tympanometry (HFT) and acoustic reflex (AR) measures obtained from infants at birth and at 6-7 weeks of age. HFT results and AR thresholds using a 2-kHz tone and broadband noise activators were obtained from 42 healthy full-term neonates (15 boys and 27 girls) at both test sessions, separated by six weeks. The results showed that the mean values of HFT test parameters and AR thresholds obtained at 6-7 weeks were generally greater than those obtained at birth. In particular, the differences in mean values of uncompensated admittance at 200 daPa, uncompensated peak admittance, uncompensated peak susceptance, peak-compensated static admittance, and AR thresholds with a 2 kHz tone and broadband noise were found to be statistically significant. The findings from this study suggest the need to have separate sets of normative LIFT and AR data for infants at birth and 6-7 weeks.

AB When the frequency range over which vent-transmitted sound dominates amplification increases. the potential benefit from directional microphones and noise reduction decreases. Fitted with clinically appropriate vent sizes. 23 aided listeners with varying low-frequency hearing thresholds evaluated six schemes comprising three levels of gain at 250 Hz (0.6. and 12 dB) combined with two features (directional microphone and noise reduction) enabled or disabled in the field. The low-frequency gain was 0 dB for vent-dominated sound. while the higher gains were achieved by amplifier-dominated sounds. A majority of listeners preferred 0-dB gain at 250 Hz and the features enabled. While the amount of low-frequency gain had no significant effect on speech recognition in noise or horizontal localization. speech recognition and front/back discrimination were significantly improved when the features were enabled. even when vent-transmitted sound dominated the low frequencies. The clinical implication is that there is no need to increase low-frequency gain to compensate for vent effects to achieve benefit from directionality and noise reduction over a wider frequency range.

AB We examine a contrast in understanding tinnitus and how this impacts on treatment approaches. First, a physiological account of tinnitus is described based on disinhibition and cortical remapping following injury at the receptor level, the analog for tinnitus being the 'phantom limb pain' phenomenon. Secondly, an experimental model of tinnitus is reviewed that relies on inference from conditioning animal behaviour. Arising from this, a role for conditioning in people distressed by tinnitus has been proposed, based on the unfounded premise that, for humans, tinnitus is a neutral stimulus, the distress being due to association with other stressful events. We critique this because we believe it influences approaches to tinnitus treatment. Finally, the phenomenology of tinnitus in the human case is analysed, with its nature illuminated via a series of distinctions with hearing impairment. Tinnitus can be intrinsically stressful for some people. Understanding this emphasizes the need to involve concepts and treatment in the area of clinical psychology. A flexible coalition between clinical audiologists and clinical psychologists is proposed as fruitful for tinnitus and related rehabilitation.

AB The aim of this study was to investigate the short-term test-retest repeatability of the TEN(H L) test. Participants comprised 15 teenagers (mean age 14 years) with long-standing severe-to-profound hearing impairment, and 20 adults (mean age 74 years) with moderate-to-severe hearing impairment. Testing was repeated using the same equipment and procedures, after an interval of less than five days. The number of cars that met the criteria for diagnosing a cochlear dead region on initial test was three (13%,) and nine (22.5%) for the teenagers and adults, respectively. Overall, the number or cars that changed category on retest was two (8%) and three (7.5%) for the teenagers and adults, respectively. Except at 1.5 and 4 kHz, the number of ears that changed category at individual frequencies was less than 5% for both groups of participants. TEN(HL) test repeatability was good when the results were categorized by ear or by frequency. The majority of ears that changed category on retest just met the dead-region criteria at an isolated frequency. An immediate retest is advisable in such cases.

AB This study investigated learning, in normal-hearing adults, associated with training (i.e. repeated practice) on the discrimination of ongoing interaural time difference (ITD). Specifically, the study addressed an apparent disparity in the conclusions of previous studies, which reported training-induced learning at high frequencies but not at low frequencies. Twenty normal-hearing adults were trained with either low- or high-frequency stimuli, associated with comparable asymptotic thresholds, or served as untrained controls. Overall, trained listeners learnt more than controls and over multiple sessions. The magnitudes and time-courses of learning with the low- and high-frequency stimuli were similar. While this is inconsistent with the conclusion of a previous study with low-frequency ITD, this previous conclusion may not be justified by the results reported. Generalization of learning across frequency was found, although more detailed investigations of stimulus-specific learning are warranted. Overall, the results are consistent with the notion that ongoing ITD processing is functionally uniform across frequency. These results may have implications for clinical populations, such as users of bilateral cochlear implants.

AB An acoustical model using simplified ear anatomy was designed to predict the ear-canal sound pressure occlusion effect in humans. These predictions were compared perceptually as well as with ear-canal sound pressure occlusion effect measurements using a foam earplug with shallow insertion, a foam earplug with deep insertion into the bony part of the ear canal, and a circumaural earmuff. There was good resemblance between model predictions and ear-canal sound pressure measurements. It was also found that all occlusion positions, even deep ear-canal occlusion, produced noticeable occlusion effects. With the bone-conduction transducer at the forehead, the perceived occlusion effect was close to that obtained from ear-canal sound pressure data in the 0.3 to 2 kHz frequency range; when the stimulation was at the mastoid the difference between the perceived and measured ear-canal sound pressure occlusion effect was around 10 dB at frequencies below 1 kHz. Further, the occlusion effect was obtained in two clinical settings: with supra-aural earphones (TDH39), and insert earphones (CIR22). Although both transducers produced occlusion effects, insert earphones produced a greater effect than surpaaural earphones at the low frequencies.

AB This experiment investigated the effect of small-group versus individual hearing loss prevention (HLP) training on the attenuation performance of passive insert-type hearing protection devices (HPDs). A subject-fit (SF) methodology, which gave naive listeners access only to the instructions printed on the HPD product label, was used to determine real-ear attenuation at threshold (REAT) at third-octave noise hands between 125-8000 Hz. REAT measurements were augmented by use of the Hearing Loss Prevention Attitude-Belief (HLPAB) survey, a field-tested self-assessment tool developed by the National Institute for Occupational Safety and Health (NIOSH). Participants were randomly assigned to one of four experimental groups, consisting of 25 listeners each, in a controlled behavioral-intervention trial. There were two types of HPDs (formable and premolded) and two training formats (individual and small group). A short multimedia program, including a practice session, was presented to all 100 listeners. Results showed training to have a significant effect, for both HPDs on real-ear attenuation and attitude, but, importantly, there was no difference between small-group and individual training.

AB A basic finding in developmental neurophysiology is that some areas of the cortex cortical areas will reorganize following a period of stimulus deprivation. In this review, we discuss mainly electroencephalography (EEG) studies of normal and deprivation-induced abnormal development of the central auditory pathways in children and in animal models. We describe age cut-off for sensitive periods for centraly auditory development in congenitally deaf children who are fitted with a cochlear implant. We speculate on mechanisms of decoupling and reorganization which may underlie the end of the sensitive period. Finally, we describe new magentoencephalography (MEG) evidence of somatosensory cross-modal plasticity following long-term auditory deprivation.

AB Research on pediatric cochlear implantation has frequently shown that speech perception, speech production, and language outcomes are better for children who are implanted earlier in life than later. These findings are often explained on the grounds that earlier implantation takes advantage of a critical or sensitive period. This paper reviews the literature concerning sensitive periods within the framework of speech and language development. It particularly emphasizes two alternate mechanisms proposed for these periods: an experience-independent mechanism, and an experience-dependent mechanism. Based on this literature review we proposed that research in the field of pediatric cochlear implantation needs to carefully define what kind of evidence is needed to reflect a sensitive period for speech and language learning. The field also needs to consider designing studies that allow the viability of these two mechanisms to be tested. An example of such a study is provided within.

AB Speech-evoked auditory brainstem responses (speech-ABR) provide a reliable marker of learning disability in a substantial subgroup of individuals with language-based learning problems (LDs). Here we review work describing the properties of the speech-ABR in typically developing children and in children with LD. We also review studies on the relationships between speech-ABR and the commonly used click-ABR. and between speech-ABR and auditory processing at the level of the cortex. In a critical examination of previously published data. we conclude that as many as 40% of LDs have abnormal speech-ABRs and that these individuals are also likely to exhibit abnormal cortical processing. Yet, the profile of learning problems these individuals exhibit is unspecific. Leaving open the question of causality, these data suggest that speech-ABR can be used to identify a large subpopulation of LDs, those with abnormal auditory physiological function. Further studies are required to determine the functional relationships among abnormal speech-ABR, speech perception, and the pattern of literacy-related and cognitive deficits in LD.

AB Changes in the distribution of language function in the brain have been documented from infancy through adulthood. Even macroscopic measures of language lateralization reflect a dynamic process of language development. In this review, we summarize a series of functional MRI studies of language skills in children ages of five to 18 years,both typically-developing children and children with brain injuries or neurological disorders that occur at different developmental stages with different degrees of severity. These studies used a battery of fMRI-compatible language tasks designed to tap sentential and lexical language skills that develop early and later in childhood.

AB The present study utilized a commercially available multiple auditory steady-state response (ASSR) system to test normal hearing adults (n=55). The primary objective was to evaluate the impact of the mixed modulation (MM) and the novel proposed exponential AM(2)/FM stimuli on the signal-to-noise ratio (SNR) and threshold estimation accuracy, through a within-subject comparison. The second aim was to establish a normative database for both stimulus types. The results demonstrated that the AM(2)/FM and MM stimulus had a similar effect on the SNR, whereas the ASSR threshold results revealed that the AM(2)/FM produced better thresholds than the MM stimulus for the 500, 1000, and 4000 Hz carrier frequency. The mean difference scores to tones of 500, 1000, 2000, and 4000 Hz were for the MM stimulus: 20 +/- 12, 14 +/- 9, 10 +/- 8, and 12 +/- 8 dB; and for the AM(2)/FM stimulus: 18 +/- 13, 12 +/- 8, 11 +/- 8, and 10 +/- 8 dB, respectively The current research confirms that the AM(2)/FM stimulus can be used efficiently to test normal hearing adults.

AB Transitory evoked otoacoustic emissions (TEOAE) have been recorded in 60 cars of 31 adult volunteers with nearly normal hearing at stimulus levels ranging from 83 dB SPL peak equivalent down to the individual response threshold using linear and nonlinear recording mode. The stimulus level dependence of response incidence and amplitude has been analysed for the integral response and in time windows selecting response components of limited latency ranges. At stimulus levels above 70 dB SPL peak equivalent the TEOAE records received in linear mode are contaminated with stimulus artifacts. At moderate stimulus levels the TEOAE amplitude differs only to a small extent between the two recording modes. At low levels the linear mode turns out to be better suited for signal detection due to its inherent lower noise level. The response threshold, defined as the highest stimulus level yielding a reproducibility of at least 60%, is significantly correlated to hearing threshold. The consideration of time windowed responses yields best results with respect to incidence and threshold of responses in the latency range between 5 and 10 ms, but it does not enhance frequency specificity.

AB This study examined racial and gender effects on behavioral thresholds and distortion-product otoacoustic emissions (DPOAEs) in the same subjects. Pure-tone behavioral thresholds and DPOAEs were measured in 60 young normal-hearing adult subjects (20 Caucasian, 20 Asian, 20 African-American, with ten females and ten males in each group). Behavioral thresholds were measured from 1000 through 16 000 Hz using Bekesy tracking. A DPOAE frequency sweep was measured with primary stimulus levels of L-1/L-2=60/45 dB SPL, and an f(2)/f(1) of 1.2 at discrete f(2) frequencies between 2000 through 12000 Hz for each subject. Significant racial and gender differences in behavioral thresholds were found at 14000 and 16000 Hz, with the African Americans and females having the best hearing sensitivity. Based on the current results, similar findings for DPOAE frequency sweeps can be expected amongst different racial groups given that no significant differences were identified between the groups. To further define the effects of race and gender on auditory measures, future studies should include larger numbers of subjects, measurement of body size and middle ear reflectance, and examine emission generators.

AB The purpose of this study was to determine the validity of the nystagmus rating scale (NRS) and to assess inter- and intra-rater reliability of audiologists and experts using the scale. Face and content validity was established by eliciting feedback from two neurotologists and one neurologist. A training tape was developed to describe the rating scale and provide practice with patterns of nystagmus in benign paroxysmal positional vertigo (BPPV). Eye movements of 34 patients, ages 33 to 82 years, were videotaped using infrared/video ENG during repositioning maneuvers. Six randomly paired audiologists and six experts viewed the videotape recordings and completed the NRS for each pattern. Cohen's kappa coefficients were calculated to determine inter-rater reliability. The kappa values were 0.31 with 41% agreement for audiologists, and 0.48 with 59% agreement for experts. Intra-rater reliability for a subgroup of audiologists was 0.55 with 64%, agreement, and for experts was 0.75 with 81% agreement. In summary, even in this experienced population, additional training in viewing nystagmus patterns is needed to improve reliability among clinicians during diagnosis and treatment.

AB Cases of central deafness are rare but they can be most informative about the function and dysfunction of the central auditory nervous system. Previous information on the anatomy, physiology, and terminology related to central deafness is reviewed and a patient with central deafness is profiled. The patient suffered bilateral cerebrovascular accidents (CVAs) compromising Heschl's gyrus and some adjacent neural tissue on both sides of the brain, At 18 months post CVAs, this patient could not understand speech presented solely through the auditory modality. Environmental sounds were perceived, but rarely recognized. Pure-tone testing revealed a severe-to-profound hearing loss bilaterally, but otoacoustic emissions, acoustic reflexes, and the auditory brainstern response were essentially within normal ranges for both ears. Middle late and late auditory potentials were compromised, yielding complex modifications of the waveforms. These findings and the compromised vascular anatomy in this case are detailed in this article.

DE psychosocial experience of late deafness
ID DEAFENED ADULTS; HEARING-LOSS; EXPERIENCES; IMPAIRMENT
AB The psychosocial impact of 'late' deafness in adults has received little research attention. The aim of this study was to examine the views of people with experience of late deafness living in the UK. Eight participants (six male; age range 33 to 60) were interviewed by a researcher who had undergone appropriate communication skills training. In-depth. face-to-face, semi-structured interviews were conducted and transcribed. Data were analysed using framework analysis to identify themes. Becoming deafened was a devastating experience for many participants who experienced severe psychological, social, and employment consequences. They no longer felt they belonged in the hearing world, and neither did they belong in the prelingually deaf world. Onset of deafness had left them in a twilight zone between worlds and had robbed them of their identity. Whilst the support received from health and social care professionals was mixed, all participants valued the peer support and training received on an intensive rehabilitation programme delivered by deafened people. Findings provide insight into deafened peoples' psychosocial experiences and emphasize the need for support and advice.

AB The aim of this research was to develop, digitally record, evaluate, and equate speech audiometry materials that can be used to measure the speech reception threshold (SRT) in quiet for native speakers of Taiwan Mandarin. Familiar trisyllabic words were digitally recorded by male and female talkers of Taiwan Mandarin and subsequently evaluated by 20 native listeners with normal hearing at 14 intensity levels (-10 to 16 dB HL) in 2 dB increments. Using logistic regression, psychometric functions were calculated for all words. Twenty-eight words with comparatively steep psychometric functions were selected and digitally adjusted to match the mean subject pure-tone average (5.0 dB HL). This resulted in a list of words that are relatively homogeneous in threshold audibility and psychometric function slope. The mean slopes for the 28 selected male and female trisyllabic Taiwan Mandarin words were 11.3%dB and 11.7%dB respectively.

ID DISEASE
AB Sudden hearing loss is a very rare complication of interferon-alpha treatment. At this time, hearing loss in patients treated with pegylated interferon and ribavirin has only been described in two reports. We present a case of a 27-year-old patient who was diagnosed with Turner syndrome, treated for hepatitis C with pegylated interferon and ribavirin, and suffered from hearing loss during the 10(th) week of treatment. Audiometric examination revealed a bilateral sensorineural hearing loss (SNHL). Auditory brainstem response (ABR) measures confirmed the diagnosis. We decided to comply with the patient's request to continue therapy. which only led to slight further deterioration of the patient's hearing ability. However, IS months after the end of therapy a follow-up audiometric examination disclosed a bilateral SNHL.

TI Test-retest reliability of distortion-product otoacoustic emissions in
   children with normal hearing: A preliminary study
SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
DE DPOAEs; children hearing; reliability
ID EARS
AB The test-retest reliability of DPOAEs was investigated in 24 children (43 ears) with normal hearing at five F2 frequencies (2530, 3561, 5014, 7029. and 10 028 Hz). Two DPOAE recordings were performed on the same subjects in the same location using the same equipment. The second recordings were made 13 to 15 days after the first recording.. The DPOAE level recorded in the subjects ranged between -13.10 and 20.20 dB for all the five frequencies. The variation in DPOAE level was greater at 10 028 Hz than at other frequencies. The mean difference between the test and retest recordings was 0.52 +/- 2.87, 1.57 +/- 4.62, 0.01 +/- 3.38, -0.55 +/- 2.85, and -0.56 +/- 5.57dB at 2530, 3561, 5014, 7029, and 10 028 Hz, respectively. The intra-correlation coefficients for DPOAE level at each of the five (F2) frequencies were 0.85, 0.68, 0.62, 0.89, and 0.64 respectively. Calculations of mean +2SD showed that retest recordings greater than 6.26, 7.67, 6.81, 5.15, and 10.58 dB SPL at 2530, 3561, 5014, 7029, and 10 028 Hz respectively could possibly be interpreted as a significant change in status of the ear.

ID OTITIS-MEDIA; EPIDEMIOLOGY; EFFUSION; COHORT
AB The aims were to: (1) provide word recognition thresholds (WRTs) at 31, 43, and 61 months of age; (2) investigate developmental changes over tirne (3) investigate the relationship between OME and WRT, and (4) investigate the relationship between WRT and hearing thresholds. Around 1000 children were tested longitudinally its part.rthe ALSPAC study. using an adaptive measure of word recognition in quiet. Mean WRTs were 28, 23, and 23 dB (A) at 31, 43, and 61 months, respectively. Normal auditory development is associated with a mean improvement in WRT of 5 dB between age 31 and 61 months. There was it mean increase in WRT of + 5 dB and + 15 dB when OME was present in one and two ears, respectively. Thus, both unilateral and bilateral OME results in a detrimental effect on hearing ability for speech. Additionally, early and 'persistent' OME is associated with greater disability. However by 61 months, previous OME status was not significant. To our knowledge, this is the largest longitudinal study reporting WRT in preschool children with different middle ear status.

AB Recent recommendations to record cochlear microphonic (CM) activity in auditory brainstem response (ABR) waveforms are being driven by reports of 'especially prominent' (Starr et al, 2001, p. 92) CM activity in ABR waveforms that were absent or grossly abnormal. This paper adds to these recommendations by providing the first description of especially prominent CM activity in ABR waveforms that were present and not grossly abnormal. The implications of this description are discussed via a review of the possible non-pathophysiological and pathophysiological causes of especially prominent CM activity in auditory evoked potentials.

AB Results from a large study of adults who completed a randomized crossover study of listening and communication enhancement (LACE (TM)) training were analysed to observe trends. The objective of this study was to determine predictors for greatest improvement following this four-week adaptive auditory training and aural rehabilitation program. Subjects with the poorest scores on the baseline tests, particularly those with the greatest degree of hearing loss, poorest scores on measures of degraded and competing speech, and those with the highest hearing handicap scores, were more likely to have greater improvement overall. However, there was considerable variability among the subjects, and some subjects' positive subjective reports belie smaller overall measured gains. Information collected from both the testing and the counseling of the patient should be taken into consideration when determining whether to proceed with LACE (TM) training.

AB The aim of the study is to understand the implications of disclosing the results of connexin26 (Cx26) gene testing to the concerned family with hearing impaired individuals. The department of biotechnology is funding a multicentric multidisciplinary team from Jawaharlal Nehru Center for Advanced Scientific Research (Bangalore), AYJNIHH (Mumbai), PGIBMS (Chennai), and MAMC (New Delhi) to profile mutations of deafness genes in India. Under this program, blood samples were taken from various centers and were sent to JNCASR for genetic analysis (screening for Cx26 mutations). This case study is an attempt to bring out issues encountered when disclosing the implications of genetic diagnosis to the concerned family.

AB The main purpose of this study is to examine the applicability of an adaptive and interactive optimization strategy to fine-tune three hearing-aid algorithms simultaneously: dynamic compression, temporal signal enhancement, and noise reduction. The optimal combination of these three algorithms was determined by a multidirectional pattern search with an adaptive step size. Additionally, we applied a round-robin procedure to validate the results of the optimization procedure. For both procedures the listeners were asked to compare two consecutive, differently processed sentences in continuous and fluctuating background noises on speech intelligibility. Ten hearing-impaired and four normal-hearing subjects participated. The reliability and consistency of the multidirectional pattern search was low, especially for the fluctuating noise condition. The results of the round-robin procedure did not correspond closely with the pattern search results. These findings suggest that the current implementation of a multidirectional optimization procedure has not yet proven to be applicable for the necessary individual fine tuning of complex signal processing strategies. when the objective is to maximize speech intelligibility.

AB The transiently evoked otoacoustic emission amplitude of 42 preterm babies (84 cars; post-conceptional age [PCA] 30-36 weeks) was compared with the TEOAE amplitude of 39 full-term babies (78 ears; PCA 37-45 weeks) in order to trace the inner ear maturation characteristics. An ILO-92 otoacoustic emission recording system Was used with linear clicks of 70 dB peak equivalent SPL. The results obtained indicated: (1) There was no statistically significant difference between preterm and full-term ears; (2) There was no significant difference between males and females; (3) There was a significant difference between left and right car TEOAE amplitude: (4) The interaction of ear with age in relation to TEOAE amplitude was statistically significant; (5) Noise and stimulus parameters did not reveal any significant differences between right and left ears; (6) A positive correlation existed between birthweight and TEOAE amplitude; and (7) A negative correlation existed between aminoglycoside treatment and TEOAE amplitude. The results indicate subtle changes in TEOAE amplitude over time, showing a natural development of the inner ear function during the process of maturation.

AB Contralateral suppression of transient otoacoustic emissions in 42 premature babies (84 ears; post-conceptional age [PCA] 30-36 weeks) was compared to that of 39 fullterm babies (78 ears; PCA: 37-45 weeks). Eighteen healthy adults and ten young children (5-14 years old) were studied as controls. Risk factors for hearing loss were registered in both preterm and full-term groups. An ILO-92 otoacoustic emission recording system was used to deliver linear clicks to the ear examined and broadband noise to the contralateral ear in an alternating on and off mode.
   Suppression in full-term babies was statistically higher than in preterms, whereas no differences existed between children and adults and children and full-terms. Peripheral auditory lateralization was evident it) adults but was observed only as a trend in newborns. Only prematurity at the time of examination and aminoglycoside treatment for more than seven days had a negative impact on suppression.
   The results support the conclusion that maturation of the efferent system takes place from 30 to 45 weeks PCA. The exact age at which this maturation is accomplished has not yet been clearly determined.

ID HEARING THRESHOLDS; AUDIOMETRY; CHILDREN
AB Infants with hearing loss routinely receive hearing aids several months before reliable behavioral responses to amplified sound can be observed. This necessitates objective measures to validate hearing-aid fittings. A single report has demonstrated the use of ASSRs to determine aided thresholds in children but data in young infants is still lacking. The current study explored aided ASSR compared to unaided ASSR thresholds and subsequent behavioral thresholds in a group of six young infants with hearing loss who received hearing aids between three and six months of age. Aided ASSR thresholds were obtained in 83% of frequencies where aided behavioral thresholds were obtained, with a mean threshold difference of 13 +/- 13 dB. The aided ASSR-based threshold estimates were within 15 dB of behavioral thresholds in 63% of cases. indicating a moderate correlation (r = 0.55). Comparing aided and unaided ASSR measurements revealed an average functional gain of 36 +/- 15 dB. These results indicate that ASSRs can provide the first evidence of robust hearing aid benefit in young infants several months before behavioral responses are observed.

AB Transposition of high-frequency information to lower frequencies may help people with high-frequency hearing loss associated with a 'dead region' (DR) to detect and identify certain consonants, such as 's'. Conventional high-frequency amplification is often not beneficial in such cases. We designed and evaluated a new tiansposition algorithm which was adapted to each subject's highfrequency DR. Frequency components from well within the DR were transposed to just within the DR without applying frequency compression. Low-frequency components were amplified, but unaffected by transposition. Transposition only occurred ifthere was significant highfrequency energy, preventing high-frequency background noise of moderate level from being transposed. Consonant discrimination was tested using vowel-consonantvowel (VCV) stimuli, and the detection of word-final 's' and 'z' was assessed using word pairs. Seven subjects with high-frequency DRs were tested in quiet using a transposed and a control condition. Following transposition, two subjects improved significantly and none performed significantly worse on the VCV-test overall. The peiception of affricates was consistently improved. Averaged across Subjects, the detection of word-final 's' and 'z' was significantly improved, with five subjects improving significantly individually.

AB Binaural interactions within the interior colliculus (IC) elicited by electric and acoustic stimuli were investigated in this study. Using a guinea pig model, binaural acoustic stimuli were presented with different time delays, as were combinations of binaural electric and acoustic Stimuli. Averaged evoked potentials were measured using electrodes inserted into the central nucleus Of the IC to obtain the binaural interaction component (BIC), computed by subtracting the Sum of the two monaural responses from the binaural response. The BICs to acoustic-acoustic stimulation and electric-acoustic stimulation were found to be similar. The BIC amplitude increased with stimulus intensity, but the shapes of the delay functions were similar across the levels tested. The gross-potential data are thus consistent with the thesis that the central auditory system processes binaural electric and acoustic stimuli in a similar manner. These results suggest that the binaural auditory system can process combinations of electric and acoustic stimulation presented across ears and that evoked gross potentials may be used to measure such interaction.

AB Newborn hearing screening is the procedure of choice for ensuring optimal outcomes for infants with hearing loss, whether in a developed or developing country. Unfortunately, apart from a small number of recent exceptions, newborn hearing screening has been a practice reserved for the developed world. Despite the prevailing challenges towards implementing hearing screening in developing countries, there are existing structures in these countries that need to be investigated as possible platforms from which programs can be actualized. Imumnization clinics. constituting part of a primary healthcare approach characteristic of developing countries, offer one such a platform. A novel service delivery model, based on initial results from a Pilot study, was developed for infant hearing screening at immunization clinics in South Africa as an integrated part of primary, secondary, and tertiary levels of healthcare. This type of model is a first step toward ensuring that infants with hearing loss in developing communities are afforded opportunities for optimal development and societal integration through accountable and contextually relevant early hearing detection and intervention services.

AB This study investigated the relationship between individual and disability characteristics and adjustment to acquired hearing loss, and the role hope has in that relationship. A sample of 114 adults with sensorineural hearing loss who had accessed hearing therapy services participated in the study. The mean age of the participants was 67 years. A survey of individual and disability characteristics. hope and adjustment was conducted. Multiple regression analyses were applied to examine possible moderating and mediating models. The results indicate that the degree of loss was the only statistically significant individual and disability characteristic related to adjustment. The trait of hope was found to serve as a mechanism by which the degree of loss affects adjustment. Hearing loss affects hope which in turn affects adjustment. Hope was found to account for 45% or the relationship between the degree of loss and adjustment. Additionally, the study round that self-efficacy and personal meaning may influence hope and despair dimensions in different ways. Discussion centres on the implication of these findings for intervention strategies used in rehabilitation programmes for those with a significant hearing loss.

DE otosclerosis; annular; diffuse; obliterative; hearing threshold;
   air-bone gap
ID REVISION STAPES SURGERY
AB Patients with diffuse obliterative otosclerosis have more extensive footplate pathology than annular cases. As a result of this more skill is required for diffuse otosclerosis cases, and postoperative hearing results are usually worse than annular cases. In this retrospective study we compared the preoperative audiological features of annular and diffuse otosclerosis patients. The subjects were 60 patients with conductive hearing loss who had undergone stapedectomy. Annular and diffuse groups were comprised of 30 patients each. Annular otosclerosis was defined as the footplate pathology involving the annular ligament only, where the footplate of the stapes is very thin and retains its bluish color. On the other hand diffuse, 0 bliterative otosclerosis was defined as the pathology involving the whole footplate and also in some cases extending beyond the confines of the annular ligament. In each group preoperative air- and bone-conduction levels at 125-6000 Hz and 500-4000 Hz were noted respectively. Average air-bone gap for the obliterative otosclerosis group was 37.5 dB; the same value for the annular group was 23.8 dB (p <0.05). The gap characteristics of the audiogram were different for the two groups. The annular group had an air-bone gap which was nearly constant for all the frequencies. In the diffuse otosclerosis group, the air-bone gap was more prominent in the low frequencies and it decreased at higher frequencies. No difference was noted in bone-conduction thresholds, and Carhart notch between the two groups. This study demonstrated that a large air-bone gap in patients with conductive hearing loss may be a sign of diffuse obliterative otosclerosis. This may warn the surgeon that a more challenging surgery is possible, and the patient may have a less favorable hearing result. Therefore, in the presence of a large air-bone gap, it may be appropriate to inform the patient of the strong possibility of diffuse otosclerosis.

AB The effect of chronic, severe tinnitus on two visual tasks was investigated. A general depletion of resources hypothesis states that overall performance would be impaired in a tinnitus group relative to a control group whereas a controlled processing hypothesis states that only tasks that are demanding, requiring strategic processes, are affected. Eleven participants who had experienced severe tinnitus for more than two years comprised the tinnitus group. A control group was matched for age and verbal IQ. Levels of anxiety, depression, and high frequency average hearing level were treated as covariates. Tasks consisted of the say-word (easy) and say-color (demanding) conditions of the Stroop task, a single (baseline) reaction time (RT) task, and dual tasks involving word reading or category naming while performing a concurrent RT task. Results supported the general depletion of resources hypothesis: RT of the tinnitus group was slower in both conditions of the Stroop task, and in the word reading and category naming conditions of the dual task.

AB The aim of this study was to evaluate the efficacy of TRT in patients suffering from tinnitus. The tinnitus disorder affects about 10-15% of the population and, in one person out of a hundred, it is a disabling disorder. TRT treatment is based on Jastreboff's neurophysio logical model. TRT consists of two parts: counselling, and sound therapy by means of dedicated hearing aids and sound generators. It proved to be useful to reduce the symptoms related to tinnitus. Jastreboff's structured interviews were proposed to a sample of 51 patients with tinnitus belonging to the I-II-III-IV classes according to Jastreb-off. These patients were treated for IS months. Sixty-eight percent of patients reported a reduction in the symptoms related to tinnitus, such as sleep disturbance, problems in concentration, and inability to relax. A percentage (64.7%) of patients thought that their quality of life was improved. Patients who had suffered from tinnitus for less than one year achieved significantly better results than patients who had suffered for a longer period of time. TRT is an effective tool in the treatment of tinnitus.

AB The aim of this study was to examine the music exposure and hearing of disc jockeys (DJs). We conducted personal noise dosimetry on 30 DJs and interviewed them regarding their hearing and their job. We conducted pure-tone audiometry, and transient and distortion product otoacoustic emissions before their exposure to music during their work. This First test was preceded by a period of at least 12 hours without exposure to music or noise. We repeated the pure-tone audiometry and otoacoustic emissions after their music exposure, and poorer performances were registered in all retests. The nightclubs' average sound level ranged between 93.2 to 109.7 dB(A). Statistical analysis showed significant bilateral temporary threshold shifts at all frequencies between audiometry performed pre- and post-exposure to amplified music. Transient otoacoustic emissions showed a significant difference in bilateral amplitude and reproducibility at all frequency bands tested. The comparison of distortion product otoacoustic emissions results pre- and post-music exposure showed there was a significant difference in amplitude. Music exposure was associated with temporary and permanent auditory dysfunction among professional DJs.

AB The objectives of the study were to describe the characteristics of the first 79 prelingually deaf cochlear implant users in Norway and to investigate to what degree the variation in speech recognition, speech-recognition growth rate, and speech production could be explained by the characteristics of the child, the cochlear implant, the family, and the educational setting. Data gathered longitudinally were analysed using descriptive statistics, multiple regression, and growth-curve analysis. The results show that more than 50% of the variation could be explained by these characteristics. Daily user-time, non-verbal intelligence, mode of communication, length of CI experience, and educational placement had the highest effect on the outcome. The results also indicate that children educated in a bilingual approach to education have better speech perception and faster speech perception growth rate with increased focus on spoken language.

AB The continuous interleaved sampling (CIS) strategy for cochlear implants has well-established limitations for the perception of pitch changes in speech. This study investigated a modification of CIS in which one channel was dedicated to the transmission of a temporal encoding of fundamental frequency (F0). Normal hearing subjects listening to noise-excited vocoders, and implantees were tested on labelling the pitch movement of diphthongal glides, on using intonation information to identify sentences as question or statement, and on vowel recognition. There were no significant differences between modified processing and CIS in vowel recognition. However, while there was limited evidence of improved pitch perception relative to CIS with simplified F0 modulation applied to the most basal channel, in general it appears that for most implant users, restricting F0-related modulation to one channel does not provide significantly enhanced pitch information.

AB We investigated the acceptability of electrophysiologically derived MAPs and the effect of these MAPs on speech perception in elderly adults using Nucleus 24 cochlear implants. Eight implant recipients aged 75 years or older trialed an electrophysiologically derived MAP and a behavioral MAP. The electrophysiologically derived MAP was based on the threshold and maximum comfort level for electrode 10 and evoked compound action potential thresholds measured on six electrodes using neural response telemetry (NRT). Word perception at 55 dB SPL and sentence perception in noise at 70 dB SPL were assessed after six weeks take-home experience and again after an additional two weeks of experience. During the final two weeks of take-home experience participants indicated their preferred MAP for different listening situations. The NRT derived MAP estimated behavioral T levels well, but underestimated behavioral C levels for apical electrodes in some subjects. Speech perception with N RT derived MAPs was comparable to speech perception with behaviorally measured MAPs. MAPs estimated from NRT data provided good speech perception outcomes for elderly implant recipients and were well tolerated.

AB The aim of the present study was to construct and compare two caloric test protocols, one for water irrigation, and one for air insufflation. A set of reference data was constructed and tabulated as well as the intersubject variability. The effect of age, sex, ear, and temperature, as well as a possible priming effect and order effect were investigated. Forty-seven subjects (18-58 years) without otological or vestibular history participated. Four response parameters were investigated: slow component velocity (SCV), frequency, unilateral weakness (UW), and directional preponderance (DP). Statistically higher SCV values were obtained for water compared to air, with statistically higher standard deviations for SCV water values. No influences of age, sex, car, or temperature could be demonstrated on any of the response parameters. The same applied for the presence of an order effect and a priming effect. Comparing the two protocols to one another led the present authors to favour water as the standard irrigation medium, and air only in situations where water is contra-indicated.

AB Previously, unilateral hearing impairment (UHI) has been considered of little consequence. However. a recent metaanalysis of children with UHI displayed educational and behavioural problems and possible delays of speech and language development, Further. patients with UHI consequently report hearing difficulties. Our study investigated hearing function, possible inner ear protection, and self-assessed hearing problems in 57 subjects aged between 3-80 years with single-sided congenital ear malformations and conductive UHI. Pure-tone thresholds and speech recognition (quiet, noise) were measured, and all patients completed a self-assessment questionnaire. Pure-tone thresholds corresponding to sensorineural function did not significantly differ between the normal (air conduction) and affected ear (bone conduction). However, speech recognition in both quiet and in noise was normal on the non-affected side but significantly worse on the malformed side. A moderate to high degree of s elf-assessed hearing problems were reported. In conclusion, hearing function in the affected ear was found to be subnormal in terms of supra threshold signal processing. Furthermore. a high degree of hearing difficulty was reported. Therefore. active treatment. surgery, or hearing amplification. might be considered.

AB Severe hearing loss among children has often been found 10 be associated with educational disadvantage and lower-than-average performance on cognitive tests. but less is known about the much more widespread milder levels of hearing loss. In a cohort of 22 162 young Danish men appearing before the draft board, about 75% had normal hearing at 20dB, and about 20%, had mild hearing loss not worse than 25 dB in both ears for all tones less than 3000 Hz, and not worse than an average of 45 dB in both ears for all tones above 2000 Hz. The remaining 5% had more severe hearing loss. The proportions who had continued school education after age 16 years among the three groups were 51%, 42% and 34% respectively and their mean IQs were 101.98 and 94. The evidence suggests that even mild hearing loss is associated with distinct educational and cognitive disadvantage which itself may result from difficulties in following classroom teaching.

AB The paper describes the outcomes of an ongoing universal hearing screening program in Tirana. Albania. The main objectives of the project were the evaluation of the feasibility of a neonatal hearing screening program in Albania, and an evaluation of the prevalence of risk factors in the NICU environment. One thousand Five hundred and sixty-one (1561) infants from both the WB and NICU were screened with transient evoked otoacoustic emissions (TEOAE). A detailed history of risk factors was collected in each case, thus it was possible to evaluate the main factors influencing the output of the screening program. It was concluded that the program had the capacity to identify infants with congenital hearing loss provided that an informative component is well-structured and delivered. Also, although the prevalence of risk factors appeared high, the reduction of 'case leakage' would allow the precise estimation of the incidence of hearing loss in the Albanian population.

AB The purpose of this paper is to deter mine ifa relationship exists between APOE alleles and non-syndroinic. sensor-ineural hearing loss (SNHL) in adults. APOE genotype was deter ruined oil DNA obtained from a sample of 89 subjects with nonsyndromic, adult onset SNHL. Median age was 64 years old, and 51 (57%) were males. Allele frequencies ill the Study population were compared to those in the general population. Subjects were divided into two groups. one by severity of hearing loss and another by severity of impairment of word recognition. Each group was stratified by severity, and allele frequencies were compared to the general population. The study found that the APOE allele epsilon 4 was less prevalent in the study population with SNHL than in the general population. No relationship was found between the epsilon 4 allele and severity of hearing loss or severity of impairment of word recognition. The study revealed t hat the APOE epsilon 4 allele was under-represented in the study sample as cornpared to the general population. Future studies associating the epsilon 4 allele with SNHL need to be population-based longitudinal or done in younger subjects.

AB The amplitude of the 2f1-f2 distortion product otoacoustic emission (DPOAE) can be suppressed by presenting contralateral acoustic stimulation. To test the hypothesis that DPOAE contralateral suppression is influenced by the primary frequency in DPgrams, DPgrams were recorded at resolutions of 1.8, and 17 pts/octave in the absence and presence of contralateral broadband noise (BBN). participants were 20 normal hearing human adults. In DPgrams with higher frequency resolutions. DPOAE suppression at amplitude peaks in DPgranis (8 pts/octave: Mean -0.92 dB, SD =0.71 for BBN at 60 dB SPL 17 pts/octave: Mean = -0.25 to 1.44 (dB. SD=0.51 to 0.86 for BBN at 40 to 70 dB SPL. respectively) was larger than the suppression at the dips in DPgrams (8 pts/octave: Mean = -0. 13 dB, SD = 1.00; 17 pts/octave: Mean = -0.03 to -0.73 dB, SD = 0.55 to 0.91). A larger intersubject variability in DPOAE contralateral suppression was observed at the dips. The results suggest that measuring DPOAE contralateral suppression at the primary frequencies corresponding to the peaks in DPgrams with higher frequency resolutions may improve the assessment of the efferent system function.

AB PAX6 encodes a transcriptional regulator that is essential for brain morphogenesis. Heterozygous PAX6 mutation is associated with aniridia and abnormalities of the interhemispheric pathway in humans. We present the case of a 12 year old boy with a known mutation of the PAX6 gene. There were parental concerns regarding his hearing, but repeated pure-tone audiograms were normal. He had a battery of standard central auditory tests, which gave abnormal results in tests which required auditory interhemispheric transfer (dichotic digits and pattern tests). A speech and language assessment, which yielded age-appropriate scores for speech, receptive and expressive language, revealed impaired verbal working memory. These test results were interpreted as indicating impaired auditory sensory and higher order interhemispheric transfer, consistent with reported findings in adults w ith mutations in PAX6, and correlated with his parent-reported hearing difficulties. This is the first report of central auditory and verbal working memory deficits in a child with a PAX6 mutation. Further research is needed to assess how these deficits impact on academic performance particularly in childhood.

AB Mobile phone ownership and usage is now widespread and public concern has developed over possible harmful physiological effects of their use. This study aimed to investigate the prevalence of student mobile phone ownership and any possible chronic effects of usage on hearing, tinnitus and balance. Questionnaires for electronic self-completion were distributed to University of Southampton postgraduates, and 117 out of 160 returned met the criteria for analysis. A total of 94% were current mobile phone users, and only 2% had never used a mobile phone. Duration of ownership and daily usage ranged from 0-7 years and 0-45 minutes respectively. Text-messaging was more popular than talking. High or long-term users reported no worse hearing, tinnitus, or balance than low or short-term users. The results of this study confirm that the prevalence of mobile phone ownership amongst students is extremely high. However there appear to be no harmful effects of mobile phone usage on their audiovestibular systems within the range of exposure of the study, insofar as can be detected by the self-report method employed.

AB The ear vulnerability of a group of combat soldiers was tested. The study initially included 84 soldiers and lasted two years. The soldiers were exposed to the noise of small-arms fire. Measurements included transient-evoked otoacoustic emissions (TEOAE) and pure-tone audiometry. Measurements, initially performed prior to the soldiers' basic training, were repeated several times during the study. In general, TEOAE levels (E) decreased over time. About 57%, of the ears developed a slight hearing loss (SHL) after two years of noise exposure. We define SHL as a threshold shift of 10 dB or greater, in at least at one of the audiometric frequencies 1000, 2000, 3000, 4000, or 6000 Hz. About 63% of the tested ears that had medium TEOAE level (1 < E-m < 8 dB SPL) prior to the noise exposure, developed SHL. On the other hand, among the ears whose E were either very low (E-m <= 1 dB SPL) or very high (E-m >= 8 dB SPL), less than 30% developed SHL. We suggest a prediction for ear vulnerability on the basis of E-m prior to noise exposure.

AB This study looked at whether a hearing education campaign would have behavioral effects on the music listening practices of high school students. A total of 1757 students participated in a hearing education campaign. Before the campaign and one year thereafter they completed a survey asking for: (1) average frequency of discotheque attendance, (2) average duration of stay in the discotheque, (3) use of earplugs in discotheques, (4) frequency of regeneration breaks while at a discotheque, and (5) mean time per week spent listening to music through headphones. On questions (2), (3) and (5) no relevant post-campaign changes were reported. On question (1) students' answers indicated that the frequency of discotheque attendance had even increased after the campaign. The only change in keeping with the purpose of the campaign was an increase in the number of regeneration breaks when at a discotheque. The effect of hearing education campaigns on music listening behavior is questioned. Additional efforts are suggested to encourage adolescents to adopt protective behaviors.

AB The objective of the study was to examine the ability to understand digits in different types of noise. Adaptive speech-in-noise tests were developed that measure the speech-reception-threshold (SRT.) i.e. signal-to-noise ratio that corresponds to 50% intelligibility. Digits were presented in continuous noise, 16-Hz interrupted noise, and 32-Hz interrupted noise. Also the standard Dutch triplet SRTn test in continuous noise was included. Results for forty-two ears of normal-hearing and hearing-impaired adult participants are presented. The ratio between the standard deviation in SRTn values between subjects and the measurement error determines the efficiency of the tests. A high efficiency could be achieved by using triplets instead of digits, or by using 16-Hz interrupted noise instead of continuous noise, because this resulted in a large spread in SRT, values. The simple calculation method of averaging presentation levels was highly efficient. The digit SRT, test in 16-Hz interrupted noise was very efficient in discriminating between normal-hearing listeners and hearing-impaired listeners, and might be used to screen for hearing loss as measured by pure-tone audiometry.

AB The objective of the study was to collect data on the Listening in Spatialized Noise - Sentences Test (LISN-S (R); Cameron & Dillon, 2006) from a group of children with normal hearing, over two test sessions, to determine test-retest reliability. The LISN-S produces a three-dimensional auditory environment under headphones, and is presented using a personal computer. Speech reception threshold (SRT) is determined for target sentences presented in competing speech that is manipulated in respect to location (0 degrees versus +/- 90 degrees azimuth) and/ or the vocal identity of the speaker/s of the stories (same as, or different to, the speaker of the target sentences). Forty-six children aged five to eleven years took part in the study. Mean changes in performance on retest on the LISN-S conditions and advantage measures ranged from 0.1 dB to 1.1 dB. Reliability (r) ranged from 0.3 to 0.8. All correlations were significant (p < 0.05). Across the range of performance measures, critical differences for test score improvements ranged from 2.5 dB to 4.4 dB, making this test suitable for detecting improvements in performance in an individual child diagnosed with central auditory processing disorder following a period of auditory compensation (such as an FM system), or training.

AB This study investigated the effects of listening condition on speech rate judgment. Four listening conditions, in which a single sentence was presented at 21 speech rates ranging from 90 wpm to 250 wpm, were incorporated. These conditions included non-degraded, reverberation, band-pa ss filtered, and low-pass littered conditions, each of which was selected to simulate listening conditions one might encounter in daily life. The participants were 20 young adults (20 to 40 years) with normal hearing. They were asked to make judgments of the rates of speech randomly presented in the four listening conditions using an equal-interval 5-step scale from too slow through too fast. Overall, speech rate was judged to be faster in the reverberant condition than in the other three conditions. These findings may have implications for auditory rehabilitation and counseling.

AB Pendred syndrome, defined as the constellation of goiter, sensori-neural hearing loss, and positive perchlorate discharge test, is the most frequent cause of congenital deafness. Newly introduced diagnostic approaches to the disease are rather expensive and complicated, therefore we evaluated the value of MRI as the sole,,or adjunctive diagnostic approach, and compared it with the traditional ones. Presuming the classic triad as the gold standard, we compared MRI findings in six such defined patients with six cases having goiter, hearing loss, and normal perchlorate discharge test. Our results indicated that MRI was 83.6% sensitive and 66.7% specific in patients fulfilling all three criteria (complete), while in the 'partial' group the sensitivity and speciticity were 66.7% and 100% respectively. In conclusion, MRI, although impressive as an adjunctive diagnostic tool, may not replace the holistic approach, and the latter may be more convenient, cheaper, and still more accurate. However in 'partial' cases with equivocal findings, and in relatives of the patients, MRI may be a valuable diagnostic adjunct.

AB Usher syndrome is both genetically and phenotypically heterogeneous. Traditionally, the condition has been classified into three clinical types, differentiated by the severity and progression of the hearing impairment and by the presence or absence of vestibular symptoms. Recent advances in molecular genetics have enabled researchers to study the phenotypic expression in confirmed molecular groups of Usher. In response to the expansion of clinical and genetic information on Usher, we report an up to date review of the different clinical forms of Usher in known molecular groups and use the emerging evidence to appraise the diagnostic utility of the traditional classification of Usher. Our findings undermine the traditional view that the clinical types of Usher have distinct genetic causes. The pleiotropic effects of some of the major causes of Usher lead to considerable overlap between the different clinical types, with very little evidence for phenotypic-genotypic correlations. The novel synthesis emerging from this review suggests more productive approaches to the diagnosis of Usher in hearing-impaired children which would provide more accurate prognostic information to families.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY

DT Article
DE T-tube; Hurler's syndrome; hearing loss
ID MUCOPOLYSACCHARIDOSES
AB Hearing loss in mucopolysaccharidosis is usually both conductive and sensorineural. The conductive component is attributable to serous otitis media secondary to dysfunction of the eustachian tube and chronic thickening of the mucosa of the middle ear. The conductive component may persist after myringotomy and insertion of short-term or long-term ventilation tubes. In Hurler's syndrome, death usually occurs in the first decade of life. In our study, we present two cases, a three-year-old girl and a four-year-old boy, who were diagnosed with Hurler's syndrome. Both children have a history of otitis media with effusion requiring repeated short-term ventilation tube insertions that were unsuccessful. Permanent t-tubes were inserted in both cases. Results showed an approximate 20 dB improvement in hearing sensitivity postoperatively for each patient.

DE hearing loss; hearing screening; children; benefits; parents'
   perspectives
ID CHILDREN; OUTCOMES
AB Newborn hearing screening has been widely implemented to improve outcomes for children with permanent hearing loss. This study examined benefits beyond those typically measured clinically, by exploring parents' perceptions of the effects of early/late identification of hearing loss. The parents of 17 children in Ontario, Canada, participated in the study. Seven children were identified through systematic screening and ten through traditional referral practices. All children were in oral rehabilitation programs. The study adopted a qualitative approach, examining parent's views through individual interviews. Purposive sampling was used to select a diverse group of parents to allow a broad range of perspectives to emerge. Benefits of early identification included improved communication development and early access to hearing. Negative aspects of late identification included regret for the family and family stress around the child's language gap. Although, screening programs may offer a seamless transition to audiology services, the transition to intervention services appeared less fluid for some families. Overall, parents strongly support infant hearing screening and identify benefits that are not easily quantifiable through traditional clinical measures.

ID HYPERTROPHIC CRANIAL PACHYMENINGITIS; HEADACHE; SPECTRUM
AB We present the case of a 68 year-old man with a diffused hypertrophic pachymeningitis (HP) involving both internal auditory canals. The clinical symptoms were headache, decreased vision in one eye, progressive bilateral and symmetrical sensory-neural hearing loss (PSNHL) responsive to steroid treatment. Although hearing loss is a frequent manifestation of HP, only few studies reported an adequate audiological assessment and follow-up. Mechanisms related to the auditory involvement are discussed on the basis of audiological data. Gadolinium enhanced MRI is the most adequate technique for HP detection and for the differential diagnosis. A delay in the diagnosis of HP seems to be quite common and the consequences may be severe, especially in cases of optic nerve involvement. For these reasons, a cerebral MRI should probably be included in the assessment of PSNHL, especially when neurological signs coexist or are reported in the medical history.

AB The aim of this study was to determine reference peak-to-peak threshold sound pressure levels for air conduction sound transducers using groups of tone bursts as test signals. For this purpose, threshold measurements with five different earphones and a loudspeaker were carried out on groups of 25 young, otologically normal test subjects in the frequency range between 250 Hz and 8000 Hz, following as closely as possible the ISO Preferred Test Conditions. The dependence of the results on repetition rate, type of sound transducer, gender and age of the test subjects, and on reference pure tone thresholds was investigated. The results mainly depend on the reference equivalent sound pressure levels for pure tones of each sound transducer. Together with the results of another study carried out in Denmark, the data of the present study will form the basis for the International Standard ISO 389 Part 6 on reference hearing thresholds for acoustic test signals of short duration.

AB Real-car measurements using the modified pressure method with concurrent (real-time) equalization can be inaccurate, when amplified sound leaks out of the ear canal and reaches the reference microphone. In such situations the reference microphone will detect an increased sound level and reduce the output of the loudspeaker to maintain the desired level. The risk of having errors due to leaks increases if digital feedback suppression (DFS) is used, thus achieving higher feedback-free gain levels. The following hypotheses were tested: a) using the concurrent equalization method for fitting hearing instruments with DFS may result in underestimated real-ear insertion gain (especially when using open fittings) and b) as the benefit of the DFS system increases, this error also increases. Real-ear measurements were carried out in twenty-one subjects using the modified pressure method with stored equalization as well as with concurrent equalization. The results of the study supports both hypotheses. As a consequence it is recommended to use a stored equalization method for real-ear measurements of hearing instruments with DFS and open fitting.

ID OBJECTIVE ASSESSMENT; POTENTIALS
AB The present study evaluated how well auditory steady state response (ASSR) and tone burst cortical evoked response audiometry (CERA) thresholds predict behavioral thresholds in the same participants. A total of 63 ears were evaluated. For ASSR testing, 100% amplitude modulated and 10% frequency modulated tone stimuli at a modulation frequency of 40 Hz were used. Behavioral thresholds were closer to CERA thresholds than ASSR thresholds. ASSR and CERA thresholds were closer to behavioral thresholds at higher frequencies than at lower frequencies. Although predictions based on CERA thresholds are slightly more accurate than ASSR thresholds, the differences may not be clinically significant, particularly when the degree of individual variations is considered. Prediction of hearing thresholds became more accurate when hearing loss increased. Due to variations in prediction across participants, a single correction factor cannot be used. Other factors must be considered in selecting whether to use CERA or ASSR in predicting behavioral thresholds.

AB Although measurement of the detection limits of the 80 Hz auditory steady-state response (ASSR) has proven to be a reasonably reliable tool in estimating hearing sensitivity in the mid-conventional audiometric frequencies (e.g. 1000 and 2000 Hz), results in the literature suggest potentially diminishing performance at 500 Hz and above 4000 Hz. The primary goal of this work was to examine the accuracy of threshold estimation via ASSR measurement for carriers more toward the audiometric extremes. At the same time, different stimulus and recording protocols than those commonly employed in ASSR testing were examined. Using a two-channel recording system, ASSRs were obtained from 15 normal-hearing young adults for an amplitude-modulated carrier of 250 Hz and repeated tone bursts of 100001 6 000 Hz, gated using a Blackman window. Results attest to the ability to record ASSRs to a wide range of carrier frequencies but also suggest that accuracy of threshold estimation suffers toward the audiometric extremes. Feasibility of ASSR-based high-frequency audiometry is demonstrated in principle, but it is not clear that this method will permit adequate sensitivity and accuracy to support such applications as ototoxicity monitoring.

AB Auditory neuropathy is a hearing disorder characterized by abnormal or absent auditory brainstem responses, and the presence of otoacoustic emissions and/or cochlear microphonics, indicating normal functioning of the outer hair cells. Here, subjects with auditory neuropathy, with near-normal hearing to moderate hearing loss, were tested using the TEN(HL) test for diagnosis of dead regions and also using psychophysical tuning curves (PTCs). Results for the majority of subjects met the TEN(HL)-test criteria at one or more frequencies (often at several or all frequencies). However, the PTCs did not show shifted tips. Hence, the positive results of the TEN(HL) test should not be interpreted as indicating the presence of dead regions. Rather, it appears that high thresholds in noise are caused by poor processing efficiency, perhaps associated with loss of neural synchrony.

AB Despite the large number of individuals who speak Russian, only a limited number of high-quality speech audiometry materials are available in a standard dialect of Russian. Thus, the purpose of this study was to develop and evaluate speech audiometry materials that can be used to measure word recognition and SRT testing in quiet for native speakers of Russian. Familiar monosyllabic and bisyllabic words were digitally recorded by male and female talkers of Russian and subsequently evaluated by native listeners. Using logistic regression, psychometric functions were then calculated for all words. Selected monosyllabic words were digitally adjusted to create word recognition lists which are relatively homogeneous with respect to audibility and psychometric slope. Speech reception threshold materials were developed by selecting twenty-five bisyllabic words with relatively steep psychometric function slopes (12.1%/dB and 9.9 %/dB) and digitally equating their intensity to match the mean PTA of the native listeners. Digital recordings of the resulting psychometrically equivalent speech audiometry materials are available on compact disc.

AB The aim of the study was to compare uncomfortable loudness levels (ULLs) in a group of adults before and after unilateral hearing aid experience. Twelve participants presented with a symmetrical hearing loss consistent with natural ageing. Pure tones were presented to each ear separately, commencing at 60 dB HL and increased in 5-dB step sizes until ULL was reached. The post-fitting ULLs were typically measured three years after fitting. Hearing thresholds were symmetrical and remained unchanged after fitting. Mean ULL values were symmetrical before fitting. The mean ULL values increased (i.e. greater tolerance) in both ears after fitting; however, the increase was greatest in the fitted ear: 14.5 and 7 dB at 2000-4000 Hz in the fitted and not-fitted ear, respectively. A separate two-factor repeated ANOVA (car and frequency) was performed on the pre and post-fitting ULL data. There was no statistically significant difference for ear (p > 0.05) when comparing the pre-fitting ULLs. However, there was a statistically significant difference for ear (p < 0.01) when comparing post-fitting ULLs. The underlying mechanism for the asymmetry is unknown but it is consistent with learning induced reorganization within the auditory system.

AB The effect of intravenously administered mexiletine on subjective tinnitus and hearing was studied in six patients, who initially responded positively to lidocame. Distinct mexlletine-induced decreases in tinnitus loudness were demonstrated in three subjects, as reflected by maximum VAS (visual analogue scale) level reduction of 34%, 95%, and 100%, respectively. One subject reported change in tinnitus pitch, another one showed a slight (18% on VAS) tinnitus reduction. and one subject disclosed no effect. Side effects were seen only during one of seven infusions. Mexiletine induced shifts in pure-tone threshold, transient evoked otoacoustic emission. and acoustic reflex threshold, probably reflecting a reversible interference in the function of organ of Corti. The concentration effect relationship remained unclear and no general 'therapeutic' level could be identified. This study confirms the effect of mexiletine on the auditory function and its potential as a possible therapeutic agent or a model for further development in tinnitus pharmacotherapy.

AB People with an acquired hearing loss often have difficulty adjusting to a first hearing aid. Studies have shown that audiological counselling can facilitate adjustment to a first hearing aid. Because of its interactive nature, the internet could be a valuable tool to gain information about the experiences of the new hearing aid user and to address the needs for audiological counselling. An internet-based audiological counselling programme in the form of daily e-mails during the first month after the hearing aid fitting was offered to three new hearing aid users. The data, qualitative in nature, were comprised of the content of the e-mails and of in-depth interviews with the participants and their audiologist, and were analysed according to grounded theory. Overall, the internet-based audiological counselling programme provided rich descriptions of the experiences of the participants and reinforced positive adjustment behaviours experienced by them.

AB Audiologists are reluctant to prescribe digital hearing aids with active digital noise reduction (DNR) to preverbal children due to their potential for an adverse effect on the acquisition of language. The present study investigated the relation between DNR and language acquisition by modeling pre-verbal language acquisition using adult listeners presented with a nonnative speech contrast. Two groups of normal-hearing, monolingual Anglophone subjects were trained over four testing sessions to discriminate novel, difficult to discriminate, non-native Hindi speech contrasts in continuous noise. where one group listened to both speech items and noise processed with DNR, and where the other group listened to unprocessed speech in noise. Results did not reveal a significant difference in performance between groups across testing sessions. A significant learning effect was noted for both groups between the first and second testing sessions only. Overall, DNR does not appear to enhance or impair the acquisition of novel speech contrasts by adult listeners.

AB The study investigated the mental health and other characteristics of people with acquired profound hearing loss (APHL) and contrasted this group with acquired hearing loss (AHL) in general. A survey was completed over the internet by 95 adults and by 27 people who had attended a one-week course of rehabilitation. The latter group completed questionnaires of anxiety and depression, post-traumatic stress. and hearing handicap. The survey covered a wide range of factors associated with the history of hearing loss and evaluated previous contacts with professional services. The data from the two samples were very similar and were combined. The results indicated the existence of sudden and progressive onset groups, reliance on lip-reading, a severe effect of tinnitus, and some support for the conclusion that the psychosocial impact was greater in APHL than in AHL. A subgroup of APHL was severely distressed and handicapped. Respondents valued medical and audiological services but there was little evidence that previous counselling and support had been helpful. Recommendations for rehabilitation are briefly discussed.

AB Previous investigation of an experimental, wearable frequency-compression hearing aid revealed improvements in speech perception for a group of listeners with moderately sloping audiograms (Simpson et al, 2005). In the frequency-compression hearing aid, high frequencies (above 1600 Hz) were amplified in addition to being lowered in frequency. Lower frequencies were amplified without frequency shifting. In the present study, an identical frequency-compression scheme was evaluated in a group of seven subjects, all of whom had steeply sloping hearing losses. No significant differences in group mean scores were found between the frequency-compression device and a conventional hearing instrument for understanding speech in quiet. Testing in noise showed improvements for the frequency-compression scheme for only one of the five subjects tested. Subjectively, all but one of the subjects preferred the sound quality of the conventional hearing instruments. In conclusion, the experimental frequency-compression scheme provided only limited benefit to these listeners with steeply sloping hearing losses.

AB This work was undertaken to answer the question, 'How does the speech audibility/fit-to-gain-target provided by compression change with number of channels?' For each of 957 audiograms and a given number of compression channels, the channel crossover frequencies were set either to maximize the SII (speech intelligibility index) for low-and high-level speech spectra, or to optimize the fit-to-gain targets from the Cambridge method for loudness equalization (CAMEQ). The audiograms comprised all common configurations, and losses ranged from mild to severe. Use of these computational procedures allowed the predicted, channel-number-based performance to be determined separately from the effects of other compression parameters. From one to five channels were sufficient to yield predicted speech recognition performance within 5% of maximum for 90% of the 'mild' and 'moderate' audiograms. Three to nine channels were necessary for the same level of predicted performance for 90% of the 'severe' audiograms. Four channels or fewer were sufficient to produce less than 5 dB rms error in fit to CAMEQ targets for 90% of all audiograms.

AB There is no standardized material to assess auditory processing (AP) in Spanish-speaking adults. The purpose of this research was to develop and obtain initial normative data for AP tests for Spanish-speaking adults. The AP tests comprised the Hong Kong CAPA (Hong Kong central auditory processing assessment) including speech-in-noise, binaural fusion, filtered speech, and dichotic digit tests. In addition five tests already developed by other authors, but with no normative data reported for the target population, were included in the study. These tests were staggered spondaic words, random gap detection, pitch pattern sequence, duration pattern sequence, and masking level difference. Forty normal hearing Chilean adults were assessed to obtain the initial normative data. Several correlations were found between tests and between subtests within the same test category. 90(th) percentiles are suggested as initial normative data.

AB A cross-sectional epidemiological study on prevalence of hearing loss was carried out in an age- and Down's syndrome- stratified random sample of 1598 persons drawn from a base population of 9012 persons, representative of the Dutch adult population of intellectual disability (ID) service users. The re-weighted population prevalence is 30.3% (95% confidence interval [CI]: 27.7-33.0%). Subgroup prevalences range from 7.5% (95% confidence interval [CI]: 3.6-13.3) in the subgroup aged 18-30 years with ID by other causes than Down's syndrome, up to 100% (95% CI: 79.4-100%) in adults over 60 years of age with Down's syndrome. Down's syndrome (OR 5.18, 95% CI 3.80-7.07) and age were confirmed to be risk factors. Age-related increase in prevalence in persons with Down's syndrome appears to occur approximately three decades earlier, and in persons with ID by other causes approximately one decade earlier than in the general population.

ID PROFOUND HEARING IMPAIRMENT; QUALITY-OF-LIFE
AB Cochlear implantation (CI) rates vary between countries, depending on identification routines and economic restrictions. The present study aimed at determining the prevalence of CIs in postlingually deafened, aged 20-69 years, in Goteborg, Sweden. Three patient databases with information on PTA, a questionnaire, medical records and consultations identified 88 subjects with sensorineural hearing loss >= 80 dB HL (PTA of 500, 1000, 3000 Hz), PB word score of <= 30% (better ear), regular use of hearing-aid, and oral language. The prevalence of CIs was 11.8 per 100000 population, and of subjects fulfilling the audiometric candidacy criteria 18.6 per 100000. The mean PTA (op. ear) of subjects awaiting operation was 97 dB HL (SD 12.3), and of already implanted subjects 106 dB HL (SD 10.2). Mean PB word score was 9% (SD 8.9) and 3% (SD 4.9) respectively. Subjects awaiting operation had significantly better residual hearing, emphasizing recent changes in candidacy criteria. Comparing with prevalence from other countries demonstrated that more patients could be candidates for cochlear implantation.

AB The objective of the study was to examine the effects of stimulus duration on vowel perception in normal-hearing and hearing-impaired children. For this purpose, 80 semisynthetic vowel stimuli consisting of eight different Turkish vowels with ten different durations were presented to 14 normal-hearing and 15 hearing impaired children, and they were asked to identify the vowel they heard. Thirteen normal-hearing adults served as speaker subjects to get normative data on mean durations of the Turkish vowels. While there was no significant effect of duration on perception in normal-hearing children, perception errors for very short and very long vowels were observed in hearing-impaired children. The most frequent responses as a function of duration showed four different patterns: (1) three vowels were perceived correctly in all durations; (2) two were perceived correctly in middle and longer durations; (3) two were perceived correctly in middle duration; and (4) only one was perceived correctly in short duration. It was concluded that the effects of stimulus duration on vowel perception were determined by natural duration of the vowel in a given language, and unnaturally short and long vowels were misperceived by hearing impaired subjects.

AB The purpose of this study was to examine the accuracy of self-reported hearing loss in older Latino-American adults. Fifty-nine individuals, 32 women (mean age 62.2 years) and 27 men (mean age 62.4 years), participated. The questionnaire addressed hearing loss, hearing aid use, and other people's views of their hearing abilities. Based on the question, 'Do you feel you have a hearing loss?', the prevalence of self-reported hearing loss was 57.6%, with 56.3% of women and 59.3% of men reporting a hearing loss. Sensitivity, specificity, and accuracy were calculated using this question and compared to the pure-tone average (PTA) at 500, 1000, 2000, and 4000 Hz in the poorer ear. Overall, sensitivity was 75.7%, specificity was 72.7%, and accuracy was 74.6%. Results of this smaller scale study suggest that a single question, used as a screening measure, is both sensitive and specific for hearing loss in older Latino-American adults and may overcome language and cultural barriers. This question can be easily implemented by physicians or other healthcare employees to quickly screen for hearing loss.

AB This study examined the effect that signal processing strategies used in modern hearing aids, such as multi-channel WDRC, noise reduction, and directional microphones have on interaural difference cues and horizontal localization performance relative to linear, time-invariant amplification. Twelve participants were bilaterally fitted with BTE devices. Horizontal localization testing using a 360 degrees loudspeaker array and broadband pulsed pink noise was performed two weeks, and two months, post-fitting. The effect of noise reduction was measured with a constant noise present at 80 degrees azimuth. Data were analysed independently in the left/right and front/back dimension and showed that of the three signal processing strategies, directional microphones had the most significant effect on horizontal localization performance and over time. Specifically, a cardioid microphone could decrease front/back errors over time, whereas left/right errors increased when different microphones were fitted to left and right ears. Front/back confusions were generally prominent. Objective measurements of interaural differences on KEMAR explained significant shifts in left/right errors. In conclusion, there is scope for improving the sense of localization in hearing aid users.

AB Evoked potential thresholds using the 40 Hz auditory steady-state response (ASSR) and cortical auditory evoked potential (CAEP) were recorded at 500 Hz and 4000 Hz test frequencies in 36 subjects with normal acuity, and 30 subjects with sensorineural hearing loss. ASSR threshold sensation levels (SLs) were lower in ears with greater degrees of hearing loss, and for the 500 Hz stimulus. Mean SLs (maximum duration of a single recording: 89 seconds) were as follows at 500 Hz and 4000 Hz respectively: normal hearing group, 16.9 +/- 10.3 dB and 42.4 +/- 14.4 dB; mild-moderate group, 10.6 +/- 8.8 dB and 23.8 +/- 8.1 dB; severe-profound group, 10.0 +/- 13.2 dB and 21.5 +/- 18.9 dB. CAEP SLs showed no change with hearing level and CAEP/behavioural differences were similar at each test frequency. Mean SLs for CAEP threshold (single recording duration: 84 seconds) at 500 Hz and 4000 Hz respectively were: normal hearing group, 10.3 +/- 6.4dB and 11.5 +/- 3.8dB; mild-moderate group, 8.4 +/- 7.4 dB and 13.2 +/- 12.4 dB; severe-profound group, 11.0 +/- 6.6 dB and 15.9 +/- 16.4 dB. The results of this study suggest that while both 40 Hz ASSR and CAEP can reflect the behavioural audiogram, CAEPs may provide a more reliable estimate of hearing in awake adults.

AB The objective of this study was to compare the electrically evoked compound action potentials, intra- versus post-operatively, in cochlear implant patients. In a prospective study twenty-five consecutively implanted adult patients received a multichannel cochlear implant. In all patients, electrically evoked compound action potentials were recorded immediately after cochlear implantation and in a post-operative setting nine months later. The threshold of the electrically evoked compound action potential was determined in both settings. A high success rate (97.4%) was found in the intra-operative setting when recording the electrically evoked compound action potential threshold per patient. The success rate per patient was significantly lower (53.4%) in the post-operative setting. Correlations between the intra- versus the post-operative ECAP thresholds were statistically significant for all electrodes tested. The ECAP thresholds were not significantly different for the two settings. The intra-operative setting is preferable for acquisition of the ECAP threshold.

AB Headphones are the standard presentation device for radio communication in the military. Although bone conduction devices possess several advantages over headphones for some military applications, they are generally considered inappropriate for inclusion in a multi-channel system. The current study tested the feasibility of a multi-channel bone conduction system by measuring the localizability of spatialized auditory stimuli presented through a pair of bone conduction vibrators. Listeners localized a Gaussian noise stimulus spatialized with individualized head-related transfer functions (HRTFs). The sounds were presented from eight virtual locations on the horizontal plane (0, 45, 90, 135, and 180) through either stereo headphones or a stereo bone conduction system. Localization performance was found to be nearly identical for both audio systems, indicating that bone conduction systems can be effectively used for displaying spatial information.

ID MIDDLE-EAR IMPLANT; FLOATING MASS TRANSDUCER; OSSICULAR CHAIN;

AB Early clinical findings are reported for subjects implanted with the Vibrant Med-El Soundbridge((R)) (VSB) device. The present criteria for the VSB, limiting its application to patients with normal middle ear function, have been extended to include patients with ossicular chain defects. Seven patients with severe mixed hearing loss were implanted with the transducer placed onto the round window. All had undergone previous surgery: six had multiple ossiculoplasties, and one had the VSB crimped on the incus with unsuccessful results. Round window implantation bypasses the normal conductive path and provides amplified input to the cochlea. Post-operative aided thresholds of 30 dB HL were achieved for most subjects, as compared with unaided thresholds ranging from 60-80 dB HL. Aided speech reception thresholds at 50% intelligibility were 50 dB HL, with most subjects reaching 100% intelligibility at conversational levels, while unaided thresholds averaged 80 dB HL, with only one subject reaching 100% intelligibility. These results suggest that round window implantation may offer a viable treatment option for individuals with severe mixed hearing losses who have undergone unsuccessful ossiculoplasties.

AB The purpose of this investigation was to compare the effects of monaural and binaural stimulation on unilaterally-measured vestibular evoked myogenic potential (VEMP) magnitude and latency. The subjects were eighteen normal-hearing adults with no history of vestibular disease. Monaural VEMPs were acquired with air-conducted (AC) and bone-conducted (BC) 500 Hz tone bursts presented at 95 dB nHL and 70 dB nHL, respectively. These stimuli were simultaneously paired with 95 dB nHL contralateral tone bursts at 250, 500, 750, or 1000 Hz during acquisition of binaural VEMPs. Results indicated that AC-VEMP relative magnitudes decreased in each of the binaural conditions compared to the monaural condition. However, no changes in relative magnitude between conditions occurred for BC-VEMPs. Similar latencies were observed for monaural and binaural VEMPs. Differences in bilateral interaction seen between the AC-VEMP and BC-VEMP conditions are consistent with modification of sound transmission through the ear during presentations of binaural sound.

TI Speech masking release in listeners with flat hearing loss: Effects of
   masker fluctuation rate on identification scores and phonetic feature
   reception

ID AMPLITUDE-MODULATED NOISE; RECOGNITION; PEOPLE
AB Consonant identification was measured for a stationary and amplitude-modulated noise masker in four listeners with flat Cochlear hearing loss, and four age-matched normal-hearing listeners. The masker modulation rate was systematically varied between 2 and 128 Hz. Masking release (MR), that is better identification performance in fluctuating, than in stationary noise, was highest in a masker fluctuating at 8-16 Hz in all normal-hearing listeners. In comparison, MR was only observed in two out of the four impaired listeners. In these listeners, MR was poorer than normal, and peaked at lower rates, that is 2 or 8 Hz. MR corresponded to increased reception of information for voicing, place, and manner between 2 and 64 Hz in all normal-hearing listeners. In impaired listeners, increased reception of information was mainly observed for manner, and mainly reduced for place, but these differences were not significant. For all phonetic features, MR was observed at lower masker fluctuation rates ( : 32 Hz) than in normal-hearing listeners. This study therefore shows that cochlear damage affects MR, both quantitatively and qualitatively.

AB The objective of this study was to evaluate daily stressors, coping, personality, physical and mental health, and quality of life in Meniere patients. 110 consecutive patients with definite Meniere's disease were assessed using the Dutch Daily Hassles List, Coping Inventory for Stressful Situations (CISS), Symptoms Checklist 90 (SCL-90), NEO Five Factor Inventory (NEO-FFI), General Health Questionnaire (GHQ-12), and the Short Form Health Survey 36 (SF-36). Duration and subjective severity of symptoms were scored using a self-report questionnaire. It was shown that Meniere patients had more daily stressors, used certain coping strategies less often, and had more psychopathology (e.g. anxiety and depression), and a worse quality of life compared to healthy reference groups. No abnormalities in personality were found. Patients with more severe symptoms had more psychopathology and a worse quality of life than patients with mild symptoms. The psychological profile of Meniere patients seems comparable to patients with other chronic diseases. The outcomes should be used to intensify psychological support in patients with this disabling disease.

AB This study compares the occupational performance of employees with and without hearing impairment, and aims to identify occupational difficulties specifically related to hearing loss. The Amsterdam Checklist for Hearing and Work was administered to 150 hearing-impaired employees and 60 normally-hearing colleagues. A multivariate analysis of variance was performed to test group effects, and to examine differences between means. Factors predicting sick-leave were identified by regression analyses. A significant group effect (p < 0.01) was found. Hearing-impaired employees differed from normally-hearing colleagues in their perception of 'environmental noise', 'job control' and the 'necessity to use hearing activities' at work. Also, sick-leave due to distress occurred significantly more often in the hearing impaired group (p < 0.05). 'Hearing impairment', 'job demand', and the requirement to 'recognize/distinguish between sounds' were the strongest risk-factors for stress related sick-leave. The importance of hearing functions besides speech communication is discussed, Implications for rehabilitation are suggested. In future research, hearing loss should be considered as a risk factor for fatigue and mental distress which may lead to sick-leave.

AB The advent of bilateral cochlear implants (CIs) has increased interest in learning on binaural tasks, and studies in normal-hearing listeners provide important background information. However, few studies have considered learning with discrimination of interaural time difference (ITD). Here, learning with ITD was explored using stimuli that are more relevant to bilateral CIs than used previously. Inexperienced listeners were trained with envelope-based ITD using high-frequency amplitude-modulated tones with or without an interaural carrier frequency difference (IFD), the former to simulate asymmetrical bilateral CI insertions. All were tested with and without IFD before and after training. In most listeners, ITD thresholds improved substantially with training, not necessarily reaching asymptote after 3000 trials. In these, the magnitude and time-course of learning was larger than anticipated from a previous study with low-frequency ITD. Learning generalized across IFD and the effect of IFD on ITD thresholds at post-test was smaller than reported previously These results have implications for studies of bilateral CIs, such as the need to provide extensive training to avoid over-estimating any apparent 'impairment'.

AB The objective of this study is to verify the effects of gap marker spectrum on gap-evoked auditory responses. The gap-evoked potentials were recorded using electrodes implanted in the inferior colliculus (IC) and auditory cortex (AC) of guinea pigs. The gap markers were noise bursts in four frequency bands (500-8000 Hz, 500-16000 Hz, 500-32000 Hz, and 16000-32000 Hz), and were tested at three sound levels. The onset response to the post-gap marker was measured to obtain the gap response threshold, and to establish input-output functions for latency and amplitude. Similar to previous behavioural studies, it was found that the gap-response threshold decreased with increasing marker bandwidth. This change was more significant at the cortical level in which the averaged gap-threshold decreased by approximately 2 ms with the bandwidth change. However, the gap threshold in the high frequency region (16000-32000 Hz) was comparable to that of the low frequency region (500-16000 Hz). These results suggest that the total bandwidth of all auditory channels that are recruited determine the temporal resolution measured in gap-evoked potentials.

AB The objective of the study was to investigate the prevalence of congenital and early-onset hearing loss, and the influence of the known risk factors for hearing loss on infants in Jordan and Israel. Subjects were a total of nearly 17000 infants from both countries, including infants with and without risk factors for hearing loss. The hearing screening protocol included distortion product otoacoustic emission, followed in case of repeated OAE referral or high risk (HR) infant by diagnostic auditory brainstem responses. The results indicate that the prevalence and severity of hearing loss amongst Jordanian infants (1.37%) is remarkably higher as compared to the Israeli infants (0.48%). The overall prevalence of bilateral SNHL was seven times more in the Jordanian infants, 18 times in non-risk, and three times in the HR infants relative to the Israeli infants. Risk factors including family history, hyperbilirubinemia, bacterial meningitis, and associated syndromes were more prevalent amongst Jordanian infants. This unique study underscores the importance of sharing and exchanging information to create empirical data to guide health-care providers in adapting protocols to the local constraints in developing countries.

AB The objective of this study was to investigate electrode impedance in cochlear implant recipients in relation to electrically evoked stapedius reflex measurements during surgery, and to electrode design, stimulation mode, and T and C levels over a nine month period after surgery. Seventy-five implant recipients, implanted with a Nucleus straight electrode array or a Contour array, were included. The results show that: (1) during surgery electrode impedance decreases markedly after electrically evoked stapedius reflex measurements, (2) after surgery, during the period without stimulation until speech processor switch-on, impedance increases, (3) after processor switch-on impedance decreases. The lower impedance values after a period of stimulation are found at the higher T and C levels. Impedances of the straight array electrodes are lower than those of the Contour array. The difference corresponds mainly to their respective surface areas. In addition, the straight array shows a larger increase of impedance in the apical direction than the Contour array, probably because of the larger fluid environment around the basal electrodes of the straight array.

ID ANCHORED HEARING-AID; DIRECT BONE CONDUCTION; PATIENTS OPINIONS
AB The performance of the most powerful Bone-Anchored Hearing Aid (BAHA) currently available, the BAHA Cordelle, was evaluated in 25 patients with severe to profound mixed hearing loss. Patients showed bone conduction thresholds at 500, 1000 and 2000 Hz, ranged between 30 and 70 dB HL, and an additional air-bone gap of about at least 30 dB. With the BAHA Cordelle, free-field thresholds improve relative to bone-conduction thresholds with 1.5, 5.0, 17.8, and 4.3 dB at 500, 1000, 2000, and 4000 Hz, respectively, with substantial inter-individual variability. The differences in unaided air conduction thresholds and aided free-field thresholds amount to 45.3, 45.8, 47.5, and 43.5 dB at 500, 1000, 2000, and 4000 Hz, respectively. Speech perception, measured both with monosyllables of the consonant-vowel-consonant type and with bisyllables, showed highly similar results. The fitting range of a (linear) hearing aid is determined by its gain characteristics. Requiring aided speech reception thresholds at or better than 65 dB SPL results in an upper limit of the fitting range of the BAHA Cordelle for bone-conduction thresholds of 51, 56, 67, and 58 dB HL at 500, 1000, 2000, and 4000 Hz, respectively. The dynamic range provided by the BAHA Cordelle was estimated from loudness growth functions at 500, 1500, and 3000 Hz employing 7-point categorical scaling. On average, aided loudness growth functions exhibit normal slopes but they level off at input levels of about 80, 70, 65 dB SPL for 500, 1500, and 3000 Hz stimuli, respectively. Measurements with a skull simulator demonstrated that the levelling-off reflects saturation of the output of the Cordelle. The relatively low saturation levels of the device suggest that increasing maximum output levels may be a worthwhile consideration for candidates with more profound sensorineural loss.

AB The objective was to examine tutors' views regarding motivation to become a lay tutor on a generic, lay-led self-management programme, 'Challenging Deafness' (CD); their experience of course delivery; and the impact of being a tutor on their own lives. Eight tutors (6 male) were interviewed face-to-face. Data were analysed using content analysis. Motivation to become a tutor was associated with desire to help others and establish a new purpose in life. Tutors derived a satisfaction from sharing experiences with course participants and felt their contribution to the welfare of others was valued not only by course participants, but also by friends, family and society. Delivering CD courses reinforced tutors' own self-management, helped develop new skills (e.g. giving presentations), and enhanced confidence. Challenges associated with the tutor role included fatigue, travelling to venues, and managing some course participants. Although tutors felt supported in their role, some felt that advertising materials should reflect the psychosocial nature of the course. Several tutors suggested course modifications specific to the needs of deafened adults.

AB This study evaluated the use of landline and mobile phones in an international sample of cochlear implant users. A custom-designed survey was mailed to cochlear implant users from four different countries. A link to the survey was posted on the MED-EL website, with responses from a further six countries. Results from 196 surveys show that there is a significant shift from preoperative non-use of a telephone to use of a telephone post-operatively. Seventy-one percent of MED-EL cochlear implant users are able to use a landline telephone to some extent and 54% are able to use a mobile phone to some extent. Talking to familiar speakers about familiar topics is the easiest listening condition on the telephone, and it is easier to recognize a voice using the landline. Many respondents found it difficult to make a call without some assistance. Most respondents could manage to call someone in an emergency, even on a mobile phone. Data obtained should provide useful information in the counselling and rehabilitation of cochlear implant recipients and candidates.

   LESIONS; PLASTICITY; DAMAGE; CATS
AB The aim of the present study was to investigate the simple reaction time (RT) performance of patients with steeply sloping sensorineural hearing loss. This kind of bearing loss has the particularity of inducing a reorganization of the primary auditory cortex (Dietrich et al, 2001), the edge frequency of the loss being over-represented. It is assumed that a consequence of this plasticity could be reflected in an improvement in frequency discrimination performances around the edge of the loss (McDermott et al, 1998). In the present study we used pure tones equalized in loudness to investigate whether RT might be altered at the cut-off frequency (Fc) of the loss, or at the frequency that presented the best discrimination-limen-for-frequency (bDLF). The effect of auditory rehabilitation on RT was also studied. A great variability in RT was noted in all our subjects. Our results demonstrated that RT was unmodified at Fc or bDLF, be it before or after hearing aid fitting. However, an improvement in the correlation between RT and frequency discrimination performance was observed at three months post-rehabilitation.

AB A dead region (DR) is a region of the cochlea where there are no functioning inner hair cells and/or neurones. We compared the edge frequencies, f(e), of DRs estimated using four methods: the TEN(HL) test; psychophysical tuning curves (PTCs) measured in simultaneous masking (320-Hz wide noise masker) using a 'fast' method (sweeping masker) and a 'classical' method; and PTCs measured in forward masking (sinusoidal masker) using a 'classical' method. Fourteen subjects with high-frequency DRs were tested. For measurement of PTCs, the signal frequency was chosen to fall inside the DR; the tip frequencies of the PTCs were taken as indicating the values off,. The values off, obtained from the PTCs in forward and simultaneous masking (both fast and classical methods) were similar and were usually close to, but somewhat above, the values off estimated from the TEN(HL) test. Fast PTCs measured in simultaneous masking are recommended for use in clinical practice, as they give a precise estimate of f(e) and are quick to administer.

AB The reliability of the Auditory Steady State Response (ASSR) has not been thoroughly evaluated despite its recent application as a clinical tool for threshold estimation. The purpose of this study was to examine test-retest (TR) reliability of ASSR threshold estimates in an empirical research design. The ASSR, tested using modulation frequencies approximately 80 Hz and above, was evaluated against pure tone audiometry (PTA), and the slow vertex potential (SVP, N-1-P-2). Sixteen normal-hearing young female adults were tested twice, one week apart. Varying degrees of sensorineural hearing loss of a notched configuration were simulated with filtered masking noise. Test-retest reliability was assessed using Pearson-product moment correlation analysis, supplemented by other post-hoc analyses. Results demonstrated moderately strong TR reliability for ASSR at 1000, 2000 and 4000 Hz (r = 0.83-0.93); however, the reliability of ASSR at 500 Hz was weaker (r = 0.75). Results suggest that ASSR-ERA is a reliable test at mid -high frequencies, at least with the configuration and degrees of simulated sensorineural hearing loss examined in this study.

AB This study focussed on self-report outcome in new hearing-aid users. The objectives of the experiment were changes in self-report outcome over time, and relationships between different subjective measures of benefit and satisfaction. Four outcome inventories and a questionnaire on auditory lifestyle were administered to 25 hearing-aid users repeatedly after hearing-aid fitting, and assessments took place one week, four weeks, and 13 weeks after hearing-aid provision. The results showed that, for first-time users who used their hearing aids more than four hours per day, self-reported outcome increased over 13 weeks in some scales, although there was no change in amplification during this time. Furthermore, it was found that, for data collected immediately post-fitting, some subscales were much less face valid than for data collected later. This result indicates that the way in which hearing-aid users assess outcome changes over time. The practical consequence of the results is that early self-report outcome assessment may be misleading for some self-report outcome schemes.

AB The purpose of this study was to evaluate a new clinical assessment, the Dynamic Assessment of Hearing Aids (DANA), for a large clinical population. Unlike traditional questionnaire methods, the DANA has patients use an intuitive graphical computer interface to record visual analogue ratings of satisfaction with various features of their hearing aids (e.g. clarity, cost, appearance). Data were collected from 191 participants. A subset of participants returned for retest. The DANA items assess satisfaction with hearing aids within four domains: communication, physical features, sound quality, and personal reactions. The concurrent validity was determined by comparing DAHA results to those obtained with the satisfaction with amplification in daily life (SADL). Ratings for personal reactions to hearing aids indicate the most satisfaction, and ratings for communication (especially group conversations and phone use) indicate the least satisfaction. The DAHA total score was found to have good test/retest and high internal consistency. Concurrent validity was supported by a strong correlation between total scores on the DAHA and the SADL. Results suggest the DANA maybe an effective tool for clinical use.

AB The aim of this study was to assess the effects of fitting a hearing aid by measuring the benefits derived from hearing aid use. Besides andiologic tests, a short version of the Hearing Handicap Inventory for the Elderly, and the EuroQol questionnaire were used in a prospective study. Ninety-eight first-time hearing aid users were interviewed prior to, and six months after, the fitting of their first hearing aids. The total HHIE-S score changed from 28.7 before, to 12.7 six months after, hearing aid fitting. Altogether 40%-60% of the users reported fewer social or emotional problems. There was a statistically significant positive change in the EQ-VAS score. According to the HHIE-S, hearing aids clearly alleviated hearing disability. The EQ-5D questionnaire was not sensitive enough for measuring the health-related quality of life of subjects with hearing impairment.

AB The objective of this paper is to evaluate the advantages of the Advanced Bionic high resolution mode for speech perception, through a retrospective analysis. Forty-five adult subjects were selected who had a minimum experience of three months' standard mode (mean of 10 months) before switching to high resolution mode. Speech perception was tested in standard mode immediately before fitting with high resolution mode, and again after a maximum of six months high resolution mode usage (mean of two months). A significant improvement was found, between 11 and 17%, depending on the test material. The standard mode preference does not give any indication about the improvement when switching to high resolution. Users who are converted within any study achieve a higher performance improvement than those converted in the clinical routine. This analysis proves the significant benefits of high resolution mode for users, and also indicates the need for guidelines for individual optimization of parameter settings in a high resolution mode program.

AB Tympanometry using 226 Hz, 678 Hz, and 1000 Hz probe tones was undertaken on two groups of babies, age 2 to 21 weeks. A group of 104 babies with normal ABR thresholds or TEOAEs were compared with a second group of 107 babies who had evidence of temporary conductive hearing loss based on the findings of a test battery, which included air and bone conduction ABR. The tympanograms were classified by Method 1, a simple visual classification system, and Method 2, adapted from a system described by Marchant et al (1986). The majority of tympanograms recorded in both groups using the 226 Hz probe tone were 'normal' Type A, with no significant difference in middle ear pressure or static admittance. However, both classification methods demonstrated significant differences between the two groups using the higher frequency probe tones, with Method 2 being the preferred system of classification. Tympanometry using 226 Hz is invalid below 21 weeks and 1000 Hz is the frequency of choice.

AB This investigation assessed the extent to which listeners' preferences for hearing aid microphone polar patterns vary across listening environments, and whether normal-hearing and inexperienced and experienced hearing-impaired listeners differ in such preferences. Paired-comparison judgments of speech clarity (i.e. subjective speech intelligibility) were made monaurally for recordings of speech in noise processed by a commercially available hearing aid programmed with an omnidirectional and two directional polar patterns (cardioid and hypercardioid). Testing environments included a sound-treated room, a living room, and a classroom. Polar-pattern preferences were highly reliable and agreed closely across all three groups of listeners. All groups preferred listening in the sound-treated room over listening in the living room, and preferred listening in the living room over listening in the classroom. Each group preferred the directional patterns to the omnidirectional pattern in all room conditions. We observed no differences in preference judgments between the two directional patterns or between hearing-impaired listeners' extent of amplification experience. Overall, findings indicate that listeners perceived qualitative benefits from microphones having directional polar patterns.

DE expansion; compression
AB The present study investigated the subjective evaluation of expansion time constants in single-channel wide dynamic range compression (WDRC) hearing instruments. Thirty participants utilized binaural WDRC hearing instruments for a two-week trial. Subjective evaluations were conducted by having each participant rate their satisfaction with the expansion time constant on a daily basis and by having each participant indicate their preferred expansion time constant following the completion of the two-week trial. Each change in expansion time constant significantly affected listener satisfaction; however, all time constants resulted in satisfactory performance. Of the users expressing a preference, 75% preferred fast-acting over slow-acting expansion. These findings suggest that dynamic expansion parameters play an important role in determining the effectiveness of the expansion for a given listener.

AB In order to develop a sensitive audiometric protocol for identifying ototoxicity in children, a retrospective study of 16 children treated with cisplatin and/or carboplatin was performed. Audiometric testing was done by means of pure-tone threshold audiometry (PTA), high-frequency audiometry (HFA), and distortion product otoacoustic emissions (DPOAEs).
   Cisplatin caused a sensorineural high-frequency hearing loss in the study group compared to the controls (p < 0.01). Sixty-six percent of the cisplatin patients had a grade 2 or 3 ototoxicity. However, ototoxicity was not found in the patients treated with carboplatin. An excellent correlation was found between DPOAE levels and results obtained by audiometry (r =0.82).
   Patients exposed to cisplatin are at significant risk for the development of drug-induced sensorineural hearing loss. Because of the several advantages of DPOAEs (noninvasive, objective, rapid, easy to use, sensitive) this method should be added in the audiological follow-up in infants and toddlers.

AB Single and double dichotic digit tests in Malay language were developed and standardized as an initial attempt to incorporate tests of auditory processing within the scope of audiology practice in Malaysia. Normative data under free recall, directed right-ear first, and directed left-ear first listening conditions were determined using 120 Malay children between the ages of 6 and I I years old with normal hearing and normal academic performance. Test-retest reliability was assessed in 15 of the study subjects. In general, the double dichotic digit test produced greater differences in scores between age groups, and a greater right-ear advantage than the single dichotic digit test. In addition, the double dichotic digit test also had higher test-retest reliability. These findings suggest the double dichotic digit test is more clinically applicable.

   at age 15
SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
DE acoustic reflex; stapedius reflex; otitis media; audiometric threshold;
   tympanic membrane
AB Previous research has found that childhood otitis media leads to elevated adulthood acoustic reflex thresholds because of worsened audiometric thresholds in the stimulation ear, and abnormality of the tympanic membrane in the ear from which acoustic reflexes were measured. To confirm and expand this finding, our research utilized longitudinal data from 631 general-population-sampled children assessed between ages 5 and 15. Otitis media was assessed to age 9, audiometric thresholds were measured at age 11, and otoscopy and acoustic reflex thresholds testing were performed at age 15. Our findings support the earlier research, in that acoustic reflex threshold was higher in those with the worst experience of childhood otitis media. However, this was directly mediated not by audiometric threshold in the ear to which the stimulus was delivered, but by the amount of tympanic membrane abnormality in both the stimulus and probe ears. This appeared to have an effect independent of audiometric threshold. Furthermore, only those who suffered the worst, persistent, binaural childhood otitis media showed raised acoustic reflex thresholds.

AB The objectives of this study were to (a) estimate the prevalence of auditory dys-synchrony in Mysore, a city of one million population in Southern India and, (b) present the results of audiological testing of this clinical population as well as the relationship between these figures. A register-based study design was employed wherein the results of audiological tests of all patients who visited the Department of Audiology, All India Institute of Speech and Hearing between January 2000 and December 2003 were reviewed. Results showed that the prevalence of auditory dys-synchrony was around I in 183 in individuals with sensory neural hearing loss. Behavioural thresholds and speech identification scores were variable. Around 60% of the individuals had no measurable speech identification scores. There was no relation between the hearing thresholds and speech identification scores or between otoacoustic emissions and speech identification scores. These results indicate that auditory dys-synchrony is not an extremely rare disorder.

ID HEARING IMPAIRMENT
AB Audiology in South Africa is an established profession facing the challenge of serving a diverse population in predominantly developing contexts. The profession has developed over the last half century from an adjunct to speech-language pathology into a profession in its own right. Several tertiary institutions offer undergraduate training in audiology with optional postgraduate qualifications. Institutions are continually adapting to a profession characterised by rapid change - evidenced even in the very composition of the profession itself This article aims to provide an overview of the development and current status of audiology as a profession in South Africa.

AB Objectives: Investigate the profile of young patients complaining of tinnitus and study the prevalence and the severity of tinnitus in schoolchildren.
   Design: Ninety-five consecutive patients (55 boys), 8-20 years old, seeking help for tinnitus at our clinic were studied using audiometry, structural interviews, Tinnitus Severity Questionnaire (TSQ) and Hospital Anxiety and Depression Scale (HAD), together with Visual Analog Scales (VAS) on tinnitus loudness and annoyance.
   Results: The on set of tinnitus was twice as often sudden than gradual. In 54% of the children, tinnitus had started after noise exposure, most commonly listening to music. Correlations were found between the pure-tone average (PTA) of 3, 4, and 6 kHz and TSQ scores; between TSQ and HAD subscales; and between TSQ and VAS. According to the Hospital Anxiety Depression Scale, 32% and 14.5%, respectively, were above the cut level for clinical anxiety and depressive disorders. The girls showed more signs of anxiety disorders than the boys.
   Conclusions: The majority of the help seekers had been exposed to noise, mostly music. Predisposing factors for tinnitus severity are high-frequency hearing loss and anxiety and depressive disorders.

AB The present study investigates differences between a Swedish and an American sample of young students regarding attitudes towards noise and the use of hearing protection at concerts. The study population was comprised of 179 participants from Sweden and 203 participants from the United States, who ranged in age from 17 to 21 years. Questionnaires were used to gather information on hearing symptoms and attitudes towards noise (Youth Attitude to Noise Scale). Multivariate analysis of variance revealed that attitudes towards noise differed significantly due to gender and country. Men had slightly more positive attitude towards noise than women, and men from the USA had more positive attitudes than men from Sweden. Least positive were the women from Sweden (except regarding attitudes towards the ability to concentrate in noisy environments). Multivariate logistic regression analysis was used to examine the influence of attitudes towards noise and country on young people's use of hearing protection at concerts. The results indicated that attitudes and country explained 50% of the variance in use of hearing protection.

AB The objective of this study was to investigate the clinical application of the ASSR (GSI Audera). It was completed in two parts:
   Study 1. Correlation between the ASSR-based threshold estimations and the conventional pure-tone thresholds in adults; and
   Study 2. Correlation between the average of the 2-4 kHz ASSR-based threshold estimations and c-ABR thresholds in children.
   The ASSRs were recorded in awake adults and sleeping infants with a range of hearing loss at Us of 0.5 to 4 kHz and MFs between 46 and 95 Hz. The results show that in hearing-impaired adults (thresholds > 40 dBHL) good correlations can be observed between the behavioural thresholds and the ASSR-based threshold estimations. For the normal- to near-normal-hearing adults, a significant correspondence exists between the ASSR-based threshold estimations and FPTA. In children, strong correlations were found between the c-ABR and the 24 kHz ASSR-based threshold estimation average. These studies illustrate that the GSI Audera ASSR can accurately predict the behavioural audiogram in hearing-impaired subjects. In subjects with normal hearing the individual ASSR-based threshold estimations scatter too much. Instead the average of the ASSR-based threshold estimations corresponds well with the FPTA.

AB Spectral loudness summation was measured for 10- and 1000-ms long bandpass-noise signals with bandwidths in the range of 0.2 to 6.4 kHz centered at 2 kHz for nine listeners with hearing impairment of primarily cochlear origin. Loudness matches between signals with the same duration and different bandwidth were obtained using an adaptive two-interval, two-alternative forced-choice procedure with interleaved tracks. The 3200-Hz wide reference signal had a level of 45 dB or 65 dB SPL. Every signal was individually frequency equalized prior to presentation in order to ensure audibility of all spectral components for the two reference input levels. Generally the same amount of spectral loudness summation for 10- and 1000-ms long signals was obtained for both reference levels. However, some hearing-impaired listeners show, similarly to normal-hearing listeners, a larger spectral loudness summation for short than for long duration signals, indicating that duration effects in spectral loudness summation are caused by retro-cochlear processes.

AB A research program was undertaken to evaluate the efficacy of an audiovisual-FM system as a speechreading aid. The present study investigated the effects of the distance between the talker and the speechreader on a visual-speech perception task. Sentences were recorded simultaneously with a conventional Hi8 mm video camera, and with the microcamera of an audiovisual-FM system. The recordings were obtained from two talkers at three different distances: 1.83 m, 3.66 m, and 7.32 m. Sixteen subjects completed a visual-keyword recognition task. The main results of the investigation were as follows:
   1. For the recordings obtained with the conventional video camera, there was a significant decrease in speechreading performance as the distance between the talker and the camera increased.
   2. For the recordings obtained with the microcamera of the audiovisual-FM system, there were no differences in speechreading as a function of the test distances.
   The findings of the investigation confirm that in a classroom setting the use of an audiovisual-FM system may constitute an effective way of overcoming the deleterious effects of distance on speechreading performance.

AB The BAHA (R) Softband has been developed to provide a transcutaneous anchor for a BAHA (R) until a child is a surgical candidate for the percutaneous BAHA (R) implant. We tested the objective output force level of the BAHA (R) Classic 300 and Compact connected to a Softband on an artificial mastoid to determine: (1) the effects of direct contact force on output force levels (dB); and (2) the required volume control setting to ensure audibility of speech (assuming an average adult reference equivalent threshold force level). Direct contact force was varied from 2 to 5 N in 1 N steps. Output force level increased with increasing contact force. However, the average increase was 3 dB or lower, suggesting that the contact force is of minor importance. Volume control setting appears to be of much greater importance. It is suggested that the volume setting of either device be set to at least 2.5 to ensure audibility of conversational speech. Data from normal-hearing adults with simulated conductive hearing losses are presented to validate this conclusion.

AB The aim of the study was to compare the frequency-specific effects of noise on hearing acuity across the range 250-8000 Hz and the extent to which the patterns of frequency-specific threshold shifts differ between occupational noise and impulse noise. Pure-tone audiometry was administered to an adult general population sample with 51975 subjects who also provided questionnaire information about noise exposure and other risk factors. Threshold shifts induced by life-long occupational noise and impulse noise (mostly shooting) were estimated separately in six age and sex groups for eight frequencies. Reported noise exposure, as well as observed threshold shifts, were moderate among women. Threshold shifts averaged over both ears among subjects in the higher 2% of exposure to occupational noise, reached 13 dB (3000 Hz, age 65 years+) among men and were generally largest at 3000-4000 Hz. The shifts induced by impulse noise reached approximately 8 dB among men 45-64 years and men 65 years+. The effects of impulse noise were strongest at 3000-8000 Hz and varied little within this frequency range.

AB The Competing Words Subtest is a commonly used dichotic listening test for assessing binaural integration in children suspected of having an auditory processing disorder. In 124 children, standard scores from the subtest suggested a binaural integration deficit in 23% of the children tested. Because standard scores are derived from the combined scores of both ears during the test, children with normal performance in one ear and weak performance in the other ear may be overlooked. For these children, a measure of interaural asymmetry may be a more sensitive indicator of a binaural integration deficit. When an age-appropriate criterion for interaural asymmetry from the Competing Words Subtest was used, the incidence of a binaural integration deficit increased to 51% of the children tested. Four typical patterns of dichotic listening performance were identified based on results from the two scoring techniques.

AB The validity and accuracy of the application of the auditory steady-state response (ASSR) to electric response audiometry (ERA) was tested further in a study permitting subjects to be their own controls for hearing loss. Simulated sensorineural hearing loss (SSHL) of complex configuration and varying degrees was effected using filtered masking noise. Thresholds estimated via ASSR-ERA were compared to those measured via conventional pure-tone audiometry. Further, the slow vertex potential N1-P2 was recorded to permit a comparison with an evoked-response test of common content validity and known accuracy. Results in a homogeneous subject sample demonstrated strong intertest correlation and agreement within 10 dB at 1000 to 4000 Hz (on average), but not at 500 Hz. The configurations determined by ASSR-ERA followed behavioral audiometric patterns well, except for the mildest degree of SSHL tested. Consequently, limitations of ERA remain, although ASSR-ERA appears to be quite valid overall and promises (justifiably) broad clinical applicability.

DT Article
DE benign paroxysmal positional vertigo (BPPV); migraine; nystagmus
ID EXPERIENCE
AB This article presents an approach to differentiation of migrainous positional vertigo (MPV) from horizontal canal benign paroxysmal positional vertigo (HC-BPPV). Such an approach is essential because of the difference in intervention between the two disorders in question. Results from evaluation of the case study presented here revealed a persistent ageotropic positional nystagmus consistent with MPV or a cupulolithiasis variant of HC-BPPV. The patient was treated with liberatory maneuvers to remove possible otoconial debris from the horizontal canal in an attempt, in turn, to provide further diagnostic information. There was no change in symptoms following treatment for HC-BPPV. This case was diagnosed subsequently as MPV, and the patient was referred for medical intervention. Treatment has been successful for 22 months. Incorporation of HC-BPPV treatment, therefore, may provide useful information in the differential diagnosis of MPV and the cupulolithiasis variant of HC-BPPV

SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
ID RECEPTION THRESHOLD; INTELLIGIBILITY; SENTENCES; QUIET
AB A Swedish Hearing In Noise Test (HINT), consisting of everyday sentences to be used in an adaptive procedure to estimate the speech recognition thresholds in noise and quiet, has been developed. The material consists of 250 sentences, with a length of five to nine syllables, normalized for naturalness, difficulty and reliability. The sentences were recorded with a female speaker. From the sentences, 25 phonemically balanced lists were created. All lists fluctuate less than I dB of the overall mean. The standard deviation of the test-retest difference is 0.94 dB when testing with one list, and decreases to 0.68 dB and 0.56 dB for two and three lists, respectively. The average speech recognition thresholds in noise for the Swedish sentences were -3.0 dB signal/noise ratio (SD = 1.1 dB). The present study has resulted in a well-defined and internationally comparable set of sentences, which can be used in Swedish audiological rehabilitation and research to measure speech recognition in noise and quiet.

AB The main objective of this study was to describe the outcomes of a communication education program for older people with hearing impairment using the International Outcome Inventory - Alternative Interventions (IOI-AI) and the version for significant others (IOI-AI-SO). Ninety-six people aged 58 to 94 years participated in an interactive group education program for two hours per week for five weeks. The IOI-AI was administered at one to two weeks after the last educational session and 29 significant others also completed the IOI-Al-SO at this time. Overall, positive results were obtained using both questionnaires, and satisfaction with the program was particularly high. Findings also compared favourably to reports of outcomes for other audiological interventions (i.e., another communication training program and hearing aid fitting). Principal components analysis of the IOI-AI revealed a somewhat different factor structure than the original IOI-HA. The two versions of the 101 applied in this study are recommended as simple and effective measures of the outcomes of alternative interventions.

ID CONSERVATION PROGRAM; NOISE
AB The aim of the study was to investigate the incidence and the relative risk of significant threshold shift (STS >= 15 dB deterioration at any ear and audiometric frequency) during primary military service (7-9 months), and to investigate whether subjects with an initial slight hearing loss (thresholds >= 25 dB HL at any audiometric frequency and car) were under increased risk. The investigation was made as a prospective audiometric study and included 747 men. An age-matched group of 138 individuals served as an unexposed control group, whose incidence of STS was 2.9%. In the exposed group the incidence was 7.9% and the relative risk 2.7 risk ratio (RR). In the subgroup of 95 persons, who already at reporting-for-training had a mild hearing loss, the incidence was 17%. The relative risk for STS in this group compared to the control group was 6.8 (RR), and compared to those with normal hearing at reporting was 3.1 (RR). In spite of hearing conservation efforts, hearing deterioration still occurs, above all in the artillery. Those who already at reporting-for-training had a mild hearing loss were at higher risk for STS compared to those with initially normal hearing.

AB The objective of this study was to describe and better understand the factors that influence the use of assistance technologies by older adults who have a hearing loss. We were interested in adopting a methodological approach that would provide an in-depth account of individual experiences related to the use of these technologies. A qualitative research design was therefore selected. Audio-recorded interviews were conducted with ten individuals who were 65 years of age or older and were current successful assistance technology users. Thematic analysis was used to draw meaning from the interview transcripts. The results suggest that successful use of these assistance technologies involves the recognition of hearing difficulties, an awareness that technological solutions exist, consultation for and acquisition of devices, and adapting to device use and modified behaviour. These four landmarks seem to be crucial stages when people either move toward successful assistance technology use or are discouraged from assistance technology use. Based on these results, a representative model of assistance technology awareness, acquisition and utilization is proposed.

AB We evaluated the benefits of fast-acting WDRC, slow-acting AVC. and linear reference fittings for speech intelligibility and reported disability, in a within-subject within-device masked crossover design on 50 listeners with SNHL. Five hearing aid fittings were implemented having two compression channels and seven frequency hands. Each listener sequentially experienced each fitting for a 10-week period. Outcome measures included speech intelligibility under diverse conditions and self-reported disability. At it group level, each nonlinear Fitting was superior to the linear references for benefits in listening comfort, listener satisfaction, reported intelligibility and speech intelligibility. Slow-acting AVC outperformed the fast-acting WDRC fittings for listening comfort, while for reported and measured speech intelligibility the converse was true. For listener satisfaction there were no group differences between the nonlinear fittings. Analysis in terms of Fittings for individual listeners revealed subsets with definite divergences from the group data and hence a need for candidature criteria. There are systematic differences between the benefits of nonlinear and linear fittings, and also within nonlinear fittings with fast versus slow time constants. The patterns of benefit and individual optima depend on the domain of outcome being assessed.

AB We studied candidature for linear, slow-acting AVC hearing aids, and fast-acting WDRC hearing aids in a within-subject within-device crossover design of 50 listeners with SNHL. Candidature dimensions include HTLs. ULLs, spectro-temporal and masking abnormalities, cognitive capacity, and self-reports and acoustic measures of auditory ecology Better performance with linear fittings is associated with flatter audiograms, wider dynamic range, and smaller differences in dynamic range between low and high frequencies, and also with more restricted auditory lifestyles. Better performance with all nonlinear fittings is associated with more sloping audiograms, more restricted dynamic ranges, greater differences in dynamic range between low and high frequencies, and more varied auditory lifestyles. Differential performance between WDRC and AVC Fittings is associated with patterns of variation in auditory ecology (rapid versus slow changes) and cognitive (high versus low) capacity Differential performance between WDRC in two channels, and a hybrid with WDRC in a low-frequency and AVC in a high-frequency channel is associated with psychoacoustic tests of cochlear function (high susceptibility to spectral and temporal smearing, and high susceptibility to upward spread of masking respectively). patterns of candidature include measures beyond auditory function in the domains of cognitive capacity and auditory ecology.

AB The Speech, Spatial and Qualities of Hearing Scale (Gatehouse & Noble. 2004) was applied to three independent clinical groups: 144 people prior to being fitted with amplifications 118 people with six months experience with unilateral amplification; and 42 people with six months experience with bilateral amplification. I-or traditional speech hearing contexts (one-on-one, in groups, in quiet, in noise) there was benefit with one aid, and no further benefit with two. By contrast, hearing speech in demanding contexts (divided or rapidly switching attention) showed benefit with one aid and further benefit with two. In the spatial domain, directional hearing showed some benefit with one hearing aid, and particular further benefit in distance and movement discrimination from fitting with two. There was some benefit from unilateral fitting for elements of the qualities domains (clarity, naturalness, recognisability, segregation of sounds), with no consistent sign of further benefit from two. Bilateral fitting added benefit with respect to listening effort. Two hearing aids offer advantage in demanding and dynamic contexts; these contexts are argued as significant in the maintenance of social competence and emotional wellbeing. The present results go toward establishing the real-world advantages of bilateral hearing aid fitting and suggest that previous, inconclusive clinical Findings reflect inquiry limited to more traditional areas of hearing function.

This was evaluated using a simulated conversation in a car; speech was presented to the right car and car noise was presented either to the right or both ears. In three cross-aid communication conditions, the noise in the right car was scaled and subtracted from the noise in the left car. Speech intelligibility was determined for a group of normally hearing listeners and a group with bilateral hearing loss. The hearing-impaired group had relatively higher intelligibility scores when the car noise was diotic, whereas the normal-hearing group had relatively higher intelligibility scores in the binaural (dichotic) conditions. The cross-aid conditions led to improved intelligibility compared to the reference conditions. The results indicate that the transfer of signals between hearing aids may be of benefit when listening to speech in a car.

AB The purpose of this investigation was to examine the potential for directional hearing aid benefit in listeners with severe hearing loss at multiple SNRs for both auditory only and audio-visual presentation modes. Speech recognition performance was measured using the connected speech test at six SNRs individually determined for each subject in order to avoid floor an ceiling effects. The results revealed significant directional benefit was present at all tested SNRs in the presence of visual information. For auditory only presentations, significant directional benefit was only present at the least positive SNR. The largest directional benefit was measured at the poorest tested SNR for both auditory only and audiovisual presentation modes. The results of this study generally support small but significant directional for listeners with severe hearing loss benefit in a difficult listening environment both with and without the presence of visual information.

TI Influence of artifacts and pass/refer criteria on otoacoustic emission
   hearing screening
SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
AB A screening device for otoacoustic emission (OAE) testing was evaluated via measurements of click evoked OAEs (CEOAEs) and/or distortion product OAEs (DPOAEs) obtained in normally hearing young adults and newborns. Moreover, measurements were performed in a passive cavity and in ears with severe sensorineural hearing loss, in which the occurrence of a pass result was assumed to indicate artifacts. Different parameter settings were investigated. In comparison to normally hearing young adults, overall pass rates in newborns were similar using CEOAEs (93 to 100%), but lower using DPOAEs (65 to 95% vs. 83 to 100%). Pass rates in ears with severe hearing loss were 10% at 2 kHz, 13% at 3 kHz, and lower at other frequencies. Pass rates in the test cavity were generally low. The influence of test frequency on pass rates and calculations using computer simulation indicated the presence of artifacts. The discrimination of such artifacts from biological signals is difficult or impossible, and they may represent a serious problem for efficient OAE screening.

ID SPEECH AUDIOMETRY; INTELLIGIBILITY
AB The development of a word recognition test for Modern Greek, which is comprised of three fifty-word lists, is described herein. The development was guided by four principles: 1) use of the shortest words possible (two syllables for Greek) 2) use of highly frequent words 3) phonetic balance and 4) appropriate balance of first and second syllable stress. The lists were recorded by one male and one female native speakers. Thirty-seven native speakers of Greek listened to all words by both speakers. Across lists, the mean correct identification score was 97.9% for the female voice (95% confidence interval 96.97 to 98.84) and 96.5% (95% confidence interval 95.31 to 97.77) for the male voice. This small difference was statistically significant (P <.01) and concentrated on words with first syllable stress. In future work, these recordings can be used in adult tests of speech perception and can be modified for tests of central auditory processing.

AB Among persons with intellectual disability, the prevalence of hearing impairments is high. During the German Special Olympics Summer Games 2004, a hearing screening was conducted on 755 athletes with intellectual disabilities. Obligatory screening included ear inspection and recording of otoacoustic emissions, and optional screening included tympanometry and brief pure-tone audiometry. 38.0% of the athletes failed the screening. 53.0% needed ear wax removal. 56.1% of the fails indicated sensorineural hearing loss and 13.6% indicated mixed hearing loss. 12.5% of the fails were caused by unremovable ear wax, 1.4% by ear canal affections, and 16.4% by middle ear problems. Left car fails were more frequent than right ear fails. A peripheral hearing disturbance can thus be expected in every third subject. The high failure rate, a considerable percentage of previously undetected profound hearing loss (1.1%), and the frequent need for ear wax removal, suggest that nearly half of persons with intellectual disabilities need regular otological or audiological consultations.

AB Steeply sloping high-frequency hearing loss is often associated with cochlear dead regions. These can be identified by measuring pure-tone thresholds in quiet and in Threshold-Equalising Noise (TEN). However, many patients cannot be adequately tested because the low frequencies in the TEN lead to uncomfortable loudness. We investigated the effect of high-pass filtering on the TEN-test results and the loudness of the TEN. Twenty-four normally hearing subjects and 35 subjects with steeply sloping high-frequency hearing loss were tested, using the standard TEN (TENs), and TEN high-pass filtered at 0.5 kHz (TEN0.5) or 1 kHz (TEN1). For both groups, masked thresholds did not differ across noise types for frequencies above I kHz. Over 50% of the hearing-impaired ears tested met the criteria for a dead region at 4 kHz, using all three noise types. However, masked thresholds and the prevalence of positive TEN-test results at 1 kHz were both lower with the TEN1. The TEN1 was judged the most comfortable noise by 68% of the hearing-impaired subjects. We conclude that high-pass filtering would allow testing at higher TEN levels for patients with steeply sloping hearing loss.

AB The Listening in Spatialized Noise test (LISN (R)) produces a three-dimensional auditory environment under head- phones, using only a PC and an audiometer, and was designed to provide an ecologically valid assessment of auditory figure-ground skills in children. The listener is required to indicate the intelligibility level of a story presented at 0 degrees azimuth, in the presence of distracter sentences simultaneously presented at either 0 degrees or +/- 90 degrees azimuth. Various measures assess the extent to which either spatial, vocal, or spatial and vocal cues combined, increase a listener's ability to comprehend the story, without being affected by differences between participants in variables such as linguistic skills. There was a trend of improved performance with increasing age for 48 normally hearing seven-, eight-, and nine-year-olds, and sixteen adults. Whereas some significant differences were found between adults and children, there were no significant differences in performance between the seven-, eight-, and nine-year-olds on any measure, and no significant gender or practice effects were observed. Future studies on children with suspected auditory processing disorder were considered warranted.

AB The test accuracy and prognostic validity of Multiple Auditory Steady State Responses (MSSR) and click Auditory Brainstem Responses (cABR) was compared within the context of a targeted screening protocol. A sample of 508 high-risk babies was first screened using cABR and MSSR (500 and 2000 Hz). All children (failed/pass) were called back at three to four years of age to determine their hearing status (pure-tone audiometry). Although both methods showed an equally good test performance in the first screen (sensitivity: 100% and specificity: 92-95%), the MSSR may have some potential advantage to identify low-frequency hearing loss. Furthermore, the confirmatory audiometry with MSSR predicted the child hearing status more accurately than the cABR. In conclusion, the MSSR can provide valuable information for the diagnosis and management of infants earlier detected by a screening protocol and further developed might be also useful as a screening test.

AB Confirmation of the conditions of the ossicles is essential for tympanoplasty. However, at present, ossicular mobility is experimentally estimated with palpation by a surgeon, and the results depend on the surgeon's skill. In this study, a new apparatus for quantitatively measuring ossicular mobility was developed. With this apparatus, the ossicles were displaced and the reaction force from the ossicles, (i.e. the load applied to the ossicles) was simultaneously detected. Ossicular mobility of three patients with otosclerosis or chronic otitis media was measured to evaluate the usability of the apparatus. The apparatus can distinguish the differences in ossicular mobility between normal and fixed ossicles, and it makes estimating the change of mobility between pre- and post-treatments for ossicular fixation possible. Positive correlation was seen between ossicular mobility and hearing level.

AB This study questions the basic assumption that prescriptive methods for nonlinear, wide dynamic range compression (WDRC) hearing aids should restore overall loudness to normal. Fifteen normal-hearing listeners and twenty-four hearing-impaired listeners (with mild to moderate hearing loss, twelve with and twelve without hearing aid experience) participated in laboratory tests. The participants first watched and listened to video sequences and rated how loud and how interesting the situations were. For the hearing-impaired participants, gain was applied according to the NAL-NL1 prescription. Despite the fact that the NAL-NL1 prescription led to less than normal overall calculated loudness, according to the loudness model of Moore and Glasberg (1997), the hearing-impaired participants rated loudness higher than the normal-hearing participants. The participants then adjusted a volume control to preferred overall loudness. Both normal-hearing and hearing-impaired participants preferred less than normal overall calculated loudness. The results from the two groups of hearing-impaired listeners did not differ significantly.

AB In a laboratory study, we found that normal-hearing and hearing-impaired listeners preferred less than normal overall calculated loudness (according to a loudness model of Moore & Glasberg, 1997). The current study verified those results using a research hearing aid. Fifteen hearing-impaired and eight normal-hearing participants used the hearing aid in the Field and adjusted a volume control to give preferred loudness. The hearing aid logged the preferred volume control setting and the calculated loudness at that setting. The hearing-impaired participants preferred, in median, loudness levels of -14 phon re normal for input levels from 50 to 89 dB SPL. The normal-hearing participants preferred close to normal overall loudness. In subsequent laboratory tests, using the same hearing aid, both hearing-impaired and normal-hearing listeners preferred less than normal overall calculated loudness, and larger reductions for higher input levels. In summary, the hearing-impaired listeners preferred less than normal overall calculated loudness, whereas the results for the normal-hearing listeners were inconclusive.

AB Fluctuating interfering noises are highly suitable for speech audiometry because of the large inter-individual variability in intelligibility results. This study explores the maximum duration of silent intervals in the masker as an important factor underlying sentence intelligibility in fluctuating noise. Three versions of speech-simulating fluctuating interfering noises based on the icra noises (Dreschler et al, 2001) were explored: The original noise which simulates one interfering speaker and contains pause durations up to two seconds, as well as two modified versions with pause durations limited to 250 ms and 62.5 ms, respectively. In addition, a stationary speech-shaped noise was used, Test-retest reliability as well as speech reception threshold (SRT) and speech intelligibility function slope were determined with hearing-impaired subjects. All fluctuating noises differentiated very well between subjects. Partial rank correlation analysis showed that SRTs in fluctuating noise with longest maximum pause durations mostly depended on SRTs in quiet. SRTs in fluctuating noises with smaller maximum pause durations correlated both with SRTs in quiet and in stationary noise.

AB In the present study, mild impairment of cochlear function in patients with King-Kopetzky syndrome was investigated using DPOAEs. A significant decrease in DPOAE levels in both ears was found in patients with King-Kopetzky syndrome compared with the controls after considering the thresholds as a co-variable. It is noteworthy that the global mean levels of DPOAEs were still significantly greater in controls than in patients with matched thresholds. Further frequency analyses showed a significant decrease in DPOAE levels over the mid- and high-frequency range in patients with better hearing thresholds when compared with those in the control group. Moreover, significantly smaller DPOAEs were found in the ears of patients with King-Kopetzky syndrome and without SOAEs, than in such ears of control subjects after considering the thresholds as a co-variable. However, when SOAEs were present there was no difference. Decreases in DPOAE level appear to represent evidence of minor cochlear pathology, and provide a pathological basis for the difficulty of hearing speech in the presence of background noise, which characterizes King-Kopetzky syndrome.

AB Tone-evoked Auditory Brainstem Responses (tone-burst ABRs) and Auditory Steady-State Responses (ASSRs) with 40 or 90 Hz amplitude modulation (AM) were compared. using the same equipment and recording parameters, to determine which of these three methods most accurately approached the behavioural hearing thresholds in response to 500 Hz and 2000 Hz stimuli in eleven awake adults with normal hearing.
   Estimates of the thresholds obtained with the three methods were 10, 18, and 26 dB SL at 500 Hz; and 10, 12 and 22 dB SL at 2000 Hz; using 40 Hz ASSR, 90 Hz ASSR, and tone-burst ABR, respectively. ASSRs with 40 Hz AM stimuli produced significantly better results (lowest thresholds with SD=0), whereas the wave-V analysis on the tone-burst ABR produced the poorest results. In the averaged ABRs, a robust steady-state potential was also visible. Analysis of those steady-state responses showed estimated thresholds of 13 and 14 dB SL (at 500 and 2000 Hz, respectively), thus considerably better than the estimated thresholds from the wave-V analysis.
   It is concluded that the 40 Hz ASSR showed superior results, especially at 500 Hz.

AB We examined the long-term sequelae in both ears of 42 patients who reported the occurrence of auditory changes resulting from a single exposure to intense sound levels during non-occupational activities. We divided these patients into two groups, based upon noise exposures of either continuous duration or single high-energy impulse. Audiometric data were available for each of these subjects shortly after their noise-exposure events and follow-up examinations took place more than one year after the noise occurrence (range: 1-16 years). The initial median hearing loss for the continuous-type noise exposure group at 3-8 kHz was found to be 9 dB, relative to the age-appropriate norms, in the more affected ears, and hearing function was found to have returned to normal levels at follow-up. The same initial hearing loss was measured for the impulse-type noise group, but a residual heating loss of 4 dB was measured at follow-up. Furthermore, the majority of the subjects from both groups reported tinnitus and hypersensitivity to sound at follow-up, but with minimal impact on their lives.

AB Current tympanometric norms have acknowledged the relevance of age as,in influencing factor. However, little attention has been afforded to other potentialities such its the non-pathological effects of gender, ear asymmetry, and racial heritage. This study aimed to examine normative tympanometric findings in a large sample of Chinese schoolchildren. Using a Madsen 901 Middle Ear Analyzer, data was collected from 269 children (538 ears), ranging in age from 6.2-12.7 years (mean = 9.4 years, SD = 1.7), in Jiangsu province. Descriptive statistics were calculated for the parameters of equivalent car canal volume (chi = 1.03, SD = 0.25, 90% = 0.68-1.46), peak compensated static acoustic admittance (chi = 0.58, SD = 0.34, 90% = 0.26-1.13), tympanometric width (chi = 112, SD=36, 90% = 62-156), and peak pressure (chi = -25, SD = 30, 90% = -85-+10). Statistically significant car asymmetry and grade/age effects were estabished, although differences found were minor. In comparison with past studies in Caucasian paediatric populations, the Chinese normative data displayed minimal disparities.

AB The responses of several insert earphones in the Etymotic 3A series were measured with the occluded ear simulator (IEC 60711) and the 2cc coupler (IEC 60126). Acoustic clicks following a 100 mu s rectangular voltage pulse were compared. The peak-to-peak equivalent sound pressure levels in the ear simulator were found to be 9.2 dB greater than those in the 2cc coupler. The difference wits independent of type of earphone among those tested. Similar comparisons were made for tone pips (brief tones or tone bursts) and continuous tones. For a given drive voltage, differences in earphone output were almost the same as the corresponding differences in published RETSPLs for the occluded ear simulator and 2cc coupler (ISO 389-2).

AB This paper introduces the major phenomena of binaural hearing. The sounds arriving at the two ears are rarely the same: usually one ear will be partially shadowed from the sound source by the head, and the sound will also have to travel further to get to that car. The resulting differences in interaural level and time can be detected by the auditory system and can be used to determine the direction of the source of sound. They also facilitate improvements in the detectability of a target sound masked by some other sound from some other direction. In many circumstances there is a special emphasis to the onset of a sound, which helps to perceptually suppress the complex patterns of reflections and reverberations that are present in most listening environments; yet, the auditory system is often insensitive to-and cannot take advantage of-fast dynamic changes within a sound.

AB This report presents a review of the situation in a number of countries with respect to public health policy for funding of hearing aid services in general and support to bilateral fittings in particular. The data show considerable variations among the countries studied in number of hearing aids fitted per 1000 inhabitants, differing by a factor of 6 between the extremes. Also the percentage of bilateral fittings differs with an average estimated to be of the order of 50%. For hearing-impaired children, bilateral fittings are given full financial support in most countries studied. The data presented indicate the need for a reliable, scientifically valid evidence-base regarding bilateral hearing aid fitting.

ID ROOM ACOUSTICS
AB Acoustically, a room's boundaries can be thought of as dirty mirrors. By repeated reflections, these mirrors generate multiple sound images whose intensities decrease with increasing distance. The sound energy received from these images (conditioned by the inverse square law and atmospheric absorption) sums with direct sound from the source, but with delays that are directly proportional to distance. For a time-varying signal such as speech, it is important to distinguish between 'early' and 'late' reflections. Early reflections enhance perception and arrive from fairly well defined directions. Late reflections generate both energetic and informational masking and arrive from all directions. In effect, late reflections create a diffuse, self-generated noise that adds to the noise from other sources. For all sources, there are inter-aural differences in time of arrival, sound pressure level, and spectrum, together with intra- and inter-aural effects of head movement. These differences and effects are a rich resource of information about source direction and distance, and they facilitate source segregation, selective attention, and release from both energetic and informational masking. To the extent that this information can be preserved in hearing devices, and accessed and used by hearing-impaired listeners, the potential benefits should follow. But deficits of temporal resolution, spectral resolution, bandwidth, and processing skills, together with delays and other effects of signal processing, may limit the benefits - hence the need for prescriptive and performance measures of binaural function.

ID SPEECH-PERCEPTION; OPPOSITE EARS; LOCALIZATION; NOISE
AB It is well recognised that normal hearing people use their hearing in both cars to locate sounds and to understand speech in complex listening conditions. Whereas it is standard practice to provide two hearing aids to children with bilateral hearing loss, the situation with cochlear implantation is less certain. Questions remain as to what binaural aided functioning is possible for children who use a hearing aid and a cochlear implant in opposite ears (bimodal hearing). The first part of this paper draws on research at the National Acoustic Laboratories to show that children who used bimodal hearing devices obtained binaural advantages in localization. They could also take advantage of head shadow and binaural redundancy for speech intelligibility. The second part presents data showing that some hearing-impaired children may have binaural processing deficits even when bilateral stimulation is provided. Additional strategies may be necessary to develop or enable the use of binaural cues by these children.

AB Binaural processing in normal hearing activities is based on the ability of listeners to use the information provided by the differences between the signals at the two ears. The most prominent differences are the interaural time difference and the interaural level difference, both of which depend on frequency. This paper describes the stages by which these differences are estimated by the physiological structures of the auditory system, summarizes the sensitivity of the human listener to these differences, and reviews the nature of the interaural differences in realistic environments.

AB Binaural hearing aids potentially provide binaural cues that can improve the dectability and the spatial separation of multiple sound sources. This paper considers the use of binaural cues and the resultant spatial percepts on listeners' ability to separate simultaneous sound sources. In backgrounds with continuous noise or multiple talkers, the main problem is the detection of individual acoustic components. On the other hand, if a single masking sound is very similar to the target, and both target and masker are spectro-temporally sparse, as is the case with speech, the main problem, at least for listeners with normal hearing, is to decide whether a particular spectro-temporal feature belongs to the target source and to track that source across time. Although the subjective location of a sound source can help in grouping features across time, its effect is most easily observed in the absence of other differences between the sound sources.

AB Reports of hearing disabilities, particularly those acoustically and perceptually dynamic circumstances, are associated with compromised binaural capacities. Those disabilities that are compromised largely correspond to the areas where benefits of bilateral fitting over unilateral fitting emerge. The singular exception is for disabilities in "Sound quality and naturalness". When binaural capacities are measured by traditional static masking level difference paradigms, relationships between compromised binaural capacity and self-reports of disability are largely absent. However, when masking level differences are assessed using dynamic parameters that are more representative of the conditions experienced in everyday living then significant associations between binaural capacities and self-reports of disability do emerge. We contend that, for both the self-report domain and the psychoacoustical domain, procedures should be more properly representative of the dynamic environments that listeners are routinely exposed to.

AB Successful hearing aid fitting occurs when the person fitted wears the aid/s on a regular basis and reports benefit when the aid/s is used. A significant number of people fitted with unilateral or bilateral hearing aids for the first time do not continue to use one or both aids in the long term. In this paper, factors consistently found in previous research to be associated with unsuccessful fitting are explored; in particular, the negative attitudes of some clients towards hearing aids, their lack of motivation for seeking help, inability to identify goals for rehabilitation, and problems with the management of the devices. It is argued here that success in hearing aid fitting involves the same dynamics as found with other assistive technologies (e.g., wheelchairs, walking frames), and is dependent on a match between the characteristics of a prospective user, the technology itself, and the environments of use (Scherer, 2002). It is recommended that for clients who identify concerns about hearing aids, or who are unsure about when they would use them, and/or are likely to have problems with aid management, only one aid be fitted in the first instance, if hearing aid fitting is to proceed at all. Rehabilitation approaches to promote successful fitting are discussed in light of results obtained from a survey of clients who experienced both successful and unsuccessful aid fitting.

ID LOUDNESS SUMMATION
AB In this paper, hearing aid fitting strategies are reviewed and candidature criteria for unilateral and bilateral fittings are discus sed. Fitting strategies are primarily governed by the objectives of hearing aid fitting that can be set in different ways. Based on common goals, fitting strategies can be broken down into three stages: (1) basic fitting, (2) fine-tuning and (3) verification and validation. A fine-tuning concept basing on so-called meta-controllers is described and the issue of bilateral fitting strategies is discussed. In a first order approach, bilateral hearing aids can be fitted in parallel as unilateral aids, followed by bilateral fine-tuning, making sure that loudness is balanced and overall loudness is accepted. Parallel fitting of bilateral aids is more favourable than sequential fitting to avoid rejection because of a negative experience with unilateral amplification due to difficulties in disadvantageous listening situations. Candidature criteria are presented by means of a flow chart structuring the decision making process and arriving at the conclusion that bilateral fitting should be considered the normal case. If there is any doubt about the benefit of bilateral Fitting, a trial with bilateral aids should be performed.

AB This study evaluated functional benefits from bilateral stimulation in 20 children ages 4-14, 10 use two CIs and 10 use one Cl and one HA. Localization acuity was measured with the minimum audible angle (MAA). Speech intelligibility was measured in quiet, and in the presence of 2-talker competing speech using the CRISP forced-choice test. Results show that both groups perform similarly when speech reception thresholds are evaluated. However, there appears to be benefit (improved MAA and speech thresholds) from wearing two devices compared with a single device that is significantly greater in the group with two CI than in the bimodal group. Individual variability also suggests that some children perform similarly to normal-hearing children, while others clearly do not. Future advances in binaural fitting strategies and improved speech processing schemes that maximize binaural sensitivity will no doubt contribute to increasing the binaurally-driven advantages in persons with bilateral CIs.

AB The literature on self-assessed outcomes from bilateral and unilateral hearing aid fitting is reviewed. The nature, aims, and design of different studies are quite varied, and limitations attend many of them. Nonetheless, certain indications can be extracted from the pattern of reported results. Thus, greater measured impairment, greater self-rated disability, and/or more critical contexts of listening emerge as candidate predictors of preference for, or persistence with, a bilateral fitting profile. Two matters are briefly critiqued regarding one vs two hearing aids: 1) the analogue with binocular optical correction; 2) the unaided ear ("deprivation") effect. Questions are raised about the adequacy of the range of hearing functions addressed by previous investigations of bilateral vs. unilateral fitting-and a broadened range of functions is outlined. A recent self-report-based comparison of one versus two hearing aids (Noble & Gatehouse, International Journal of Audiology, 2006) reveals that the benefit of two lies in contexts of more demanding and dynamic listening and in reduced listening effort.

AB Adult users of unilateral Nucleus CI24 cochlear implants with the SPEAK processing strategy were randomised either to receive a second identical implant in the contralateral ear immediately, or to wait 12 months while they acted as controls for late-emerging benefits of the first implant. Twenty four subjects, twelve from each group, completed the study. Receipt of a second implant led to improvements in self-reported abilities in spatial hearing, quality of hearing, and hearing for speech, but to generally non-significant changes in measures of quality of life. Multivariate analyses showed that positive changes in quality of life were associated with improvements in hearing, but were offset by negative changes associated with worsening tinnitus. Even in a best-case scenario, in which no worsening of tinnitus was assumed to occur, the gain in quality of life was too small to achieve an acceptable cost-effectiveness ratio. The most promising strategies for improving the cost-effectiveness of bilateral implantation are to increase effectiveness through enhanced signal processing in binaural processors, and to reduce the cost of implant hardware.

AB We review new recognition and localization skills in patients using one or two cochlear implant(s). We observed one unilateral patient who showed localization performance above chance. We also provide evidence for binaural processing in bilateral cochlear implant patients, even when tested with speech from the front without noise. We unsuccessfully attempted to find correlations between localization and squelch, between these variables and pre-implant threshold differences, or these variables and post-implant recognition differences. We strongly believe that new tests are needed to examine the potential benefit of two implants. We describe three tests that we use to show a binaural advantage: cued recognition, movement direction, and recognition with multiple jammers.

AB Clinicians are in the unique position of continually developing a foundation of evidence-based practice each time they evaluate a patient. This is true not only in the field of audiology, but also in all healthcare professions. Typically, evidence-based practice (EBP) is assimilated from a combination of a systematic review of current practices, practitioner experience, academic training and ongoing continuing education through review of journals, textbooks and attendance at meetings as well as informal discussions with colleagues. Clinicians are inundated with information from these sources, and they need to extract the necessary information and apply it to their specific patient population. Evidence-based practice as it applies to the non-medical treatment of hearing loss (with hearing aids) will be discussed. In addition, several studies based on clinical observations are presented for discussion.

AB Humans use several cues to determine the position of sound sources in space. Here we provide a review of the literature on how practice influences sound-localization performance in human adults. We divided this literature into two categories: adaptation to alterations in sound-localization cues and learning with normal, unaltered cues. For altered cues, partial adaptation has been reported with a variety of cue transformations, except in he extreme case in which the cues were reversed between the two ears. For normal cues, improvement has been I observed in some but not all experiments, though the most recent data generally show learning. Thus, the reviewed data indicated that human adults can recalibrate, as well as refine the use of, sound-localization cues, and that training regimens can be developed to enhance sound-localization performance in individuals with normal and impaired localization abilities.

AB This study was aimed at determining the effect of auditory experience on binaural benefits from using a cochlear implant and a hearing aid in opposite ears. Eighteen children were evaluated using tests of speech perception, horizontal localization, and functional performance when they used either a cochlear implant alone (CI) or a cochlear implant with a hearing aid (CIHA). Eight were experienced CIHA users, whereas ten had not worn a hearing aid in the non-implanted ear for up to eight years prior to participation. All children were fitted with a hearing aid in the non-implanted ear using the NAL-RP prescription, and the hearing aids were fine-tuned individually using a paired-comparisons procedure and a loudness balancing test. Evaluation results indicated that performance for all measures was significantly better with CIHA than with Cl for both groups of children. We conclude that children who receive a unilateral cochlear implant should be encouraged to wear a hearing aid in the opposite ear where there is usable residual hearing.

ID RECEPTION THRESHOLD; HEARING; REVERBERATION; DESIGN
AB Speech-in-noise audiometry has potential application as a low-cost, self-screening test for sensorineural hearing loss. To realize this potential, the influence of variations in audio equipment and listening environment need assessment. The present study assessed: 1) the frequency response and distortion produced by a wide range of commercially available audio equipment; 2) the effects of such variations upon test results with normally hearing subjects using a simple, open-set, word-identification test; 3) the effect of distortion on the speech reception threshold using digitally applied distortion; and 4) the reliability of the test in listening environments with different levels of reverberation. In addition, preliminary tests were conducted with elderly listeners. The results indicate that variations in equipment have negligible effects on speech-in-noise audiometry. The only factor that substantially elevated normally hearing listeners' thresholds was high levels of room reverberation when using loudspeaker presentation. Variations in equipment and environment thus present no significant obstacle to the development of a self-administered audiometric screening test based on speech in noise.

AB Closed-set word tests can be implemented with or without trial-by-trial visual feedback. Feedback is considered to increase subject motivation yet its influence on performance is unknown. The aim of this study was to compare performance on the Four Alternative Auditory Feature (FAAF) test with and without visual feedback over a 24-week period following fitting of a hearing aid. A total of 32 elderly subjects were recruited as new users and fitted monaurally with the same model of linear, programmable hearing aid that provided in excess of 20 dB insertion gain at 2 -4 kHz. Half of the subjects were provided with visual feedback. In these subjects, mean performance increased by 5% across the study period. The improvement in performance over time was statistically significant on analysis of variance (p <0.05). Mean performance did not increase in the remaining subjects who were not provided with feedback. If closed-set word tests are to be used with visual feedback to measure changes over time, the potentially confounding effects of practice must be controlled carefully. Alternatively, omitting feedback leads to simpler experimental designs.

AB The purpose of this study was to investigate the variables that affect psychological general well-being (quality of life) in patients with cochlear implants (CIs). The study sample consists of 96 adult patients with a Cl, aged 2486 years (Mean=61.8 yrs; SD=15.3 yrs). 48 were patients from the Sahlgrenska University Hospital in Sweden and 48 were patients from the University of Florida, USA- The Psychological General Well-being Index and the International Outcome inventory-Cochlear implants were used in collecting data. Possible independent variables were socioeconomic factors such as age, gender, nationality, living arrangement, education, and social support; as well as length of time since implantation, age when hearing loss became a problem, and subjective benefit of the Cl. A stepwise multiple regression analysis showed that 49% of the variance was explained by attitudes from others, restricted social participation, perceived social support and age.

This article presents results from a mixed method research study involving paediatric audiology services specifically. Results demonstrate significant variety in current practice with regard to routine tests and procedures, considerable variability in number of current referrals and time allocated to caseloads, and considerable variability in expectations of how the numbers will change following newborn screening implementation. The challenges of and opportunities afforded by NHSP which were identified by respondents, highlight the urgent need for further training. The study has implications for paediatric audiology services that are yet to start NHSP in the UK, as well as for services and professionals in other countries.

ID HEARING-AID EFFECTIVENESS
AB Methodology is proposed for perceptual assessment of both subjective sound quality and speech recognition in such way that results can be compared between these two aspects, Validation is performed with a noise suppression system applied to hearing instruments.
   A method termed Interpolated Paired Comparison Rating (IPCR) was developed for time efficient assessment of subjective impression of different aspects of sound quality for a variety of noise conditions. The method is based on paired comparisons between processed and unprocessed stimuli, and the results are expressed as the difference in signal-to-noise ratio (dB) between these that give equal subjective impression. For tests of speech recognition in noise, validated adaptive test methods can be used that give results in terms of speech-to-noise ratio.
   The methodology was shown to be sensitive enough to detect significant mean differences between processed and unprocessed speech in noise, both regarding subjective sound quality and speech recognition ability in groups consisting of 30 subjects. An effect on sound quality from the noise suppression equivalent to about 3-4 dB is required to be statistically significant for a single subject. A corresponding effect of 3-6 dB is required for speech recognition (one-sided test). The magnitude of difference that occurred in the present study for sound quality was sufficient to show significant differences for sound quality within individuals, but this was not the case for speech recognition.

AB This study evaluated the use of multiple auditory steady-state responses (ASSRs) and slow cortical potentials (SCPs) to estimate behavioural audiograms in adults for compensation cases. Two groups of 23 subjects were assessed using either 80 Hz or 40 Hz multiple simultaneous tones with carrier frequencies of 0.5, 1.0, 2.0, and 4.0 kHz. SCP thresholds for 0.5, 1.0, and 2.0 kHz were obtained for both groups. Mean evoked potential thresholds (dB HL) minus behavioural pure-tone thresholds (dB HL) difference scores were 5-17 dB for the 80 Hz group, 1 - 14 dB for the 40 Hz group, and 20-22 dB for the SCPs. Thresholds for 40 Hz ASSR were significantly closer to behavioural thresholds than were 80 Hz or SCP thresholds. SCP and 40 Hz ASSR audiogram estimates were obtained more quickly than the 80 Hz ASSR. Multiple 40 Hz ASSR is the method of choice for evoked potential threshold estimation in adults.

AB Post-auricular muscle responses (PAMRs) were recorded in sixteen adults with normal hearing and twenty adults with sensorineural hearing loss. Click stimuli were presented at 20 to 80 dB nHL via insert earphones. Only one ear was tested in hearing-impaired subjects, but normal-hearing subjects were tested monaurally and binaurally. PAMR amplitudes declined and latencies increased with decreasing click intensity. Both binaural stimulation and eye turn enhanced the PAMR. In hearing-impaired subjects, PAMR thresholds were correlated with audiometric thresholds for the eyes-turned condition. All normal-hearing subjects had PAMR when recording conditions were optimized and half had responses for the least optimal condition (20 dB nHL, monaural, eyes front). With eyes turned and monaural clicks at 35 dB nHL, the level widely used for infant hearing screening, most normal-hearing adults had a PAMR. Thus the PAMR is a robust response that may be a useful adjunct to ABR for objective hearing assessment.

AB The purpose of this study was to determine whether rising-frequency chirps presented via earphones with an extended high-frequency response would optimize the post-auricular muscle response (PAMR). The PAMR was recorded in adults using three different stimuli (a click, a rising-frequency chirp, and a truncated speech stimulus, /t/). Conventional ER-3A insert earphones were compared to ER-2 insert earphones to determine whether the PAMR is enhanced by the ER-2's extended high-frequency response. There were significant stimulus and earphone effects on PAMR amplitudes. The PAMR was largest for the chirp stimulus and the ER-2 earphones. The poorest responses were obtained using the /t/ stimulus and conventional ER-3A earphones. The results support previous ABR studies that have demonstrated a significant advantage of chirps over clicks for evoked response audiometry, and indicate that the PAMR is enhanced by inclusion of additional high-frequency stimulus energy.

AB A mismatch negativity response (MMN) and a new differential waveform were derived in an effort to evaluate a neural refractory or recovery effect in adult listeners. The MMN was elicited using oddball test runs in which the standard and deviant stimuli differed in frequency. To derive the differential waveform, the same standard and deviant stimuli were presented alone. MMN responses were obtained by subtracting the averaged responses to standards from the deviants. The differential waveforms were obtained by subtracting the averaged responses to standards presented alone from deviants presented alone. Scalp topography for the MMN and differential waveforms were similar. A significant (p <.05) positive and negative correlation was found between the earlier and later components of the bimodal MMN and the NI and P2 component of the differential waveform, respectively Further, N1 and P2 of the differential waveform were significant (p <.05) predictor variables of early and late peak amplitudes of the MMN. These results suggest that refractory effects may overlay/modify the morphology of the MMN waveform.

AB The effect of phonemic compression has been studied on speech intelligibility in background noise in hearing-impaired listeners with moderate-to-severe high-frequency losses. One configuration, anti-upward-spread-of-masking (anti-USOM) focuses on a release from spectral masking of high-frequency speech cues by selective spectral tilting. Release from temporal masking is the main goal of a second configuration, high-pass filtered compression (HFC), which reduces the speech modulations within a high-pass filtered compression channel. Speech intelligibility was measured with consonant-vowel-consonant (CVC) words in a multi-talker babble and a single-talker background noise. Anti-USOM has a significant negative effect on the phoneme scores in background noise. HFC compression tends to improve vowel intelligibility in a single-talker background noise, especially for the listeners with a relatively poor speech score, In a multi-talker babble noise the effects of HFC compression tend to be negative. It can be concluded that no significant release from spectral or temporal masking is obtained by the applied processing.

AB This paper presents the results from two experiments in which normal-hearing and hearing-impaired listeners used an adaptive procedure to select their preferred frequency response slope and two-channel compression ratios in twenty listening conditions. Whereas the preferred response slope mostly depended on the difference in SNR between frequency bands, the preferred output levels in two channels depended highly on the intensity level entering each band. In both cases, subjects preferred less gain in frequency bands where noise was more intrusive and they preferred less gain for listening comfort than for speech understanding. The preferred response slope also depended on the slope of the audiogram. Relative to the prescribed NAL-RP response, the preferred gain variations improved the broadband SNR and hence listening comfort, but not the estimated speech intelligibility index. Overall, the findings confirm the approach used in many commercial products of applying wide dynamic range compression in multiple bands with additional gain reductions in bands where the noise is estimated to be dominant.

AB The aim of the study was to investigate the effects of cognitive behavioral therapy (CBT) in elderly people with tinnitus ( <65 years). Thirty-seven patients were called in for a structured interview. Following exclusion, twenty-three participated in the trial. All participants under-went medical car, nose, and throat (ENT) examination, audiometry, and tinnitus matchings. A randomized controlled design with a waiting list control group was used. A CBT treatment package was delivered in six weekly two hour group sessions. Outcome was measured using validated self-report inventories and daily diary ratings of annoyance, loudness and steep quality for one week pretreatment, post-treatment. A three month follow-up was included at which time all participants had received treatment, but in a shorter format for the control group. Results showed statistically significant reductions of tinnitus-related distress. Thus, CBT was better than no treatment, but the particular aspects of CBT that contributed to the effects can not be established. In conclusion, the findings give some support for the use of group CBT for elderly people with tinnitus.

AB This study assessed the effects of stimulus misidentification and memory processing errors on immediate memory span in 25 normal-hearing adults exposed to degraded auditory input simulating signals provided by a cochlear implant. The identification accuracy of degraded digits in isolation was measured before digit span testing. Forward and backward digit spans were shorter when digits were degraded than when they were normal. Participants' normal digit spans and their accuracy in identifying isolated digits were used to predict digit spans in the degraded speech condition. The observed digit spans in degraded conditions did not differ significantly from predicted digit spans. This suggests that the decrease in memory span is related primarily to misidentification of digits rather than memory processing errors related to cognitive load. These findings provide complementary information to earlier research on auditory memory span of listeners exposed to degraded speech either experimentally or as a consequence of a hearing-impairment.

AB The objective of the study was to compare the widths of forward masking profiles in subjects implanted with the Nucleus (R) 24 Contour (TM) or straight electrode array. The Contour array is typically positioned closer to the modiolus than the straight array. Subjects were fourteen postlingually hearing-impaired adults with severe-profound hearing loss, seven used the Contour array and seven used the straight array. Forward masking profiles were measured at three positions along the array (apical, mid, and basal) using maskers at the 15% loudness level. It was hypothesized that masking profile widths would be more sensitive to differences in distance from the neural structures using low-level maskers. Masking width was calculated at the 50% point of the masking peak amplitude. There were no significant differences in masking widths between Contour and straight array subject groups. Current levels for hearing thresholds and maximum comfortable listening levels were significantly lower for the Contour array subjects.

AB Presented are results relevant to extending the utility of the auditory steady-state response (ASSR) in threshold estimation at high-frequency carriers and to the accuracy of thresholds estimated using modulation frequencies near 40 versus 80 Hz. Initially, efforts were directed at confirming various findings reported in the literature apropos effects of several basic ASSR parameters. Results supplement others' observations suggesting that ASSR detection limits overestimate behavioral thresholds for conventional audiometric (carrier) frequencies from 500 to 4000 Hz. Further investigation revealed even greater errors of threshold estimates for 8000 and 12 000 Hz, by about 14 and 22 dB on average, respectively. Although suggesting high-frequency ASSR testing to be efficacious, technical advances and additional work is needed to establish clinical utility. Comparison of effects of modulation frequency suggested ASSR thresholds with 40 Hz modulation to fall closer to behavioral threshold than those estimated at 80 Hz. Consequently, when circumstances permit, 40 Hz ASSR testing may be the method of choice (e.g. in the assessment of malingers, who may be tested awake/alert).

AB Speech recognition and cognitive functions important for speech understanding were evaluated by objective measures and by scores of perceived effort, with and without hearing aids. The tests were performed in silence, and with background conditions of speech spectrum random noise and ordinary speech. One young and one elderly group of twelve hearing-impaired subjects each participated. Hearing aid use improved speech recognition in silence (7 dB) and in the condition with speech as background (2.5 dB SIN), but did not change the perceived effort scores. In the cognitive tests no hearing aid benefit was seen in objective measures, while there was an effect of hearing aid use in scores of perceived effort, subjects reported less effort. There were no age effects on hearing aid benefit. In conclusion, hearing aid use may result in reduced effort in listening tasks that is not associated with improvement in objective scores.

AB The purpose of this study was to identify risk factors for Severe Tinnitus Suffering (STS) and to describe the results from psychiatric diagnostic interviews of STS positive and STS negative patients. Consecutive tinnitus patients (n = 127) completed the Nottingham Health Profile (NHP) and the Tinnitus Severity Questionnaire (TSQ) and answered general health questions at the first visit to the clinic and at eighteen months follow-up. Twenty-four months after the first tinnitus consultation, standardized diagnostic interviews (SCID-P), according to DSM-IIIR, were performed by an experienced psychiatrist. The calculated probability for STS was 93%, if three items from the NHP (18,32,33) were positive. STS positive patients had more anxiety disorders with more psychosocial stress and lower global assessment of function scores. Results suggest that the NHP may be a useful tool in the clinical management of tinnitus patients and emphasises the importance of identifying depressive and anxiety disorders in this population.

AB The aim of the present study was to investigate the consequences of chronic otitis media on inner ear function. Retrospective analysis of conventional puretone audiometry tests was carried out on 344 patients who were scheduled for surgical treatment of unilateral chronic otitis media without other risk factors for sensorineural hearing loss. Bone conduction thresholds of diseased ears were compared with those of contralateral, non-diseased ears. Selected clinical features were assessed among diseased ears to examine possible influences on inner ear function. Mean bone conduction threshold differences varied from 0.6 dB at 0.5 kHz to 3.7dB at 4 kHz. These differences augmented with increasing duration of middle ear disease. Impaired hearing by bone conduction thresholds of diseased ears correlated with increased age at every frequency and with an interruption of the ossicular chain only at higher frequencies. The severity of sensorineural hearing loss correlated with longer duration of middle ear disease. Thus, surgical treatment of dry and apparently stable tympanic membrane perforation is warranted.

AB Some hearing-impaired subjects report pure tones as sounding highly distorted and noise-like. We assessed whether such reports indicate that the tone frequency falls inside a dead region (DR). Nine hearing-impaired and four normally hearing subjects rated pure tones on a scale from I to 7, where I indicates clear tone and 7 indicates noise. A white noise was presented as a reference for a sound that should be rated as 7. Stimuli covered the whole audible range of frequencies and levels. The noisiness ratings were, on average, higher for hearing-impaired subjects than for normally hearing subjects. For the former, the ratings were not markedly different for tones with frequencies just outside or inside a DR. However, ratings always exceeded 3 for tones falling more than 1.5 octaves inside a DR. The results indicate that judgement of a tone as sounding noise-like does not reliably indicate that the tone frequency falls in a DR. Both normally hearing and hearing-impaired subjects rated 0.125 kHz and 12 kHz tones as somewhat noise-like, independently of the existence of a DR.

DE traditional healers; Black South Africans; hearing impairment
AB The study investigated beliefs and practices of Black South African traditional healers regarding hearing impairment. Fifteen Black South African traditional healers were interviewed using a semi-structured interview schedule. An exploratory-descriptive research design incorporating a mixed qualitative/quantitative method was employed and data were collected via individual interviews. Traditional healers reported being consulted for what could possibly reflect a variety of audiological and otological problems, and using a wide range of diagnostic and treatment techniques. Although the healers mentioned infection, organic deterioration, noise exposure, and congenital aspects as cause of hearing impairment; they tended to anthropomorphise the cause of the disease, and the reason for becoming ill was often sought in a supernatural realm. These findings have implications for culturally sensitive practice, collaboration between traditional healers and audiologists, sharing of information regarding hearing impairment, mutual referrals, and involvement of traditional healers in hearing health care.

AB The aim of this study was to compare auditory functions and to analyse the prevalence of hearing impairment and the relationship of self-reported hearing disability with audiometric test results among 75-year-old people in three Nordic localities. The representative samples came from Glostrup, Denmark (n = 571), G6teborg, Sweden (n = 450), and Jyvaskyla, Finland (n = 388). The median pure-tone thresholds were rather similar in all three populations. The prevalence of moderate hearing impairment varied between 26% and 34% in men, and between 17% and 23% in women. The corresponding figures in the prevalence of self-reported hearing difficulties were 41%-57%, and 28%-37%. The self-reported difficulties were broadly in accordance with the audiometric test results, but there also were individuals with conflicting results. It is concluded that the prevalence of hearing impairment in the three Nordic localities is fairly similar. To assess hearing disorders in elderly people, both audiometry and self-report data are needed.

AB The objective of the present study was to examine the learning effect found when using the Danish sentence test, Dantale II, in our daily clinical work. Specifically, the aim was to determine the within-visit and the inter-visit learning effects when the Dantale 11 is presented to aided hearing-impaired listeners who have not previously completed the task. Nineteen subjects participated in the study. The within-visit learning effect after listening to 160 sentences was found to be 3.2 dB, and the inter-visit learning effect was 1.6 dB with an inter-visit period range of 14-43 days. For research evaluation of algorithms or hearing aid settings, where the differences are expected to be small, it is recommended that a pool of test subjects are regularly tested using the Dantale 11 speech material. Moreover, a limitation of the number of signal processing test conditions is suggested.

AB We investigated speech perception advantages arising from the use of inter-aural time difference cues, and from the provision of redundant information by the use of a hearing aid contralateral to a cochlear implant (bimodal hearing devices). Thirty-eight subjects (14 normally hearing and 23 hearing-impaired) participated in this study. The effect of binaural redundancy was assessed by comparing the signal-to-noise ratio (SNR) required for 50% correct identification of sentences in noise when listening monaurally to that when listening binaurally. The use of inter-aural time difference cues was determined by comparing the binaural SNRs obtained with or without a noise delay of 700 mu s between ears. Results indicated adults who used bimodal hearing devices benefited from binaural redundancy, but children did not. Whereas normally hearing subjects used inter-aural time difference cues to improve speech perception in noise, neither adults nor children who used bimodal hearing devices were able to do so.

AB The purpose of this paper is to present the development process of a computer-based audiometric testing and tailored intervention program, and assess its feasibility by obtaining users' feedback. The program was implemented for 397 operating engineers at their union training center, and its feasibility was evaluated by obtaining quantitative and qualitative feedback from the participants through a survey and focus group. Over 96% of the participants indicated they liked receiving a hearing test by computer; the computer-based test worked smoothly; and the computer-based training was well organized, effective and held their interests. Almost all (more than 99%) said they would recommend this program to other workers. This project is considered as one of the first ones incorporating multimedia computer technology with self-administered audiometric testing and tailored training. Participants' favorable feedback strongly supported the continued utilization of this approach for designing and developing health screening and intervention to promote healthy behaviors.

AB This paper investigated whether smoking and short stature in adulthood were independent risk factors for hearing loss. We reanalyzed data from the Danish Work Environment Cohort Study (an existing cohort study), on prevalence of self-reported hearing loss among 7,221 employees and on five-year incidence among 4,610 employees. We found that smoking predicted hearing loss incidence and prevalence. Smoking did not predict incidence at noise exposure during half or more of a worker's hours. Very short stature predicted prevalence in the total adult population only weakly, but strongly among employees born before 1951. These prospective Findings indicate that smoking is an independent risk factor for incidence of hearing loss. Very short stature predicted prevalence of hearing loss only in a sub-population.

AB The aim of this study was the evaluation of distortion product otoacoustic emissions (DPOAEs) before and after noise exposure from shooting, and the comparison of DPOAEs with pure-tone audiometry Thirteen young male police officers were exposed to impulse noise from shooting, without using earplugs. Standard pure-tone audiometry, tympanometry, and DPOAEs were performed before exposure and at one hour post- and 24 hour post-exposure. In the one hour post-exposure testing mean pure-tone thresholds were elevated in the 1-8 kHz frequency zone and DPOAE levels were reduced at several frequencies. DPOAEs were more affected at 3 kHz or lower, whereas pure-tone thresholds were more affected at higher frequencies. After the final examination, non-significant partial shifts at high frequencies on both tests remained. Pure-tone audiometry was overall more sensitive, but DPOAEs provided additional information about the cochlear status of certain ears. These data suggest that besides behavioral testing, DPOAEs may play a role as a fast, objective, and easy to perform test for monitoring subjects exposed to impulse noise.

ID CHILDREN; IMPAIRMENT; AGE
AB International standards define normal hearing threshold levels (HTLs) and many studies describe speech recognition in noise (SRN) for adults. Less has been published on these characteristics for children. This study aims to establish ranges of HTLs and SRN for otologically normal 7-year-olds. Air conduction HTLs were measured in 189 7-year-olds within an audiometric booth. Speech recognition was measured adaptively for BKB sentences in noise presented binaurally through headphones, determining the speech-to-noise ratio (SNR) required to score 71% correct. The mean HTLs of otologically normal 7-year-olds were significantly lower (better) than those published for young adults at I and 2 kHz. Speech recognition in noise was unrelated to HTLs and was higher (worse) for 7-year-olds (SNR = -4 dB) than has been found for young otologically normal adults (SNR = -6 dB). It is concluded that although the HTLs of 7-year-old children are generally better than those of young adults, their speech recognition in noise is worse. This confirms that their ability to recognise speech in noise is not fully developed at this age.

AB This paper questions the necessity for two calibration devices to measure the acoustic output from different types of audiometric earphones, International standards give the audiometric zero for TDH39 earphones on the IEC 60318-3 acoustic couplers the IEC 60318-1 ear simulator is intended for other supra-aural earphone types, If hearing threshold samples front young, healthy cars were found to be more variable using TDH39 earphones, then that earphone and its coupler might be taken out of service. The audiological literature yielded threshold survey results for over 5100 otologically normal cars of subjects aged 31 years or less. These independent samples showed smaller variation for TDH39 samples than for samples using other earphones this finding does not support abandoning the TDH39 and its coupler, Nevertheless. benefits accrue from calibrating TDH39 output to the audiometric zero as measured on the car simulator.

AB The purpose of this study was to determine and to compare the overall intelligibility, articulation, resonance. and voice characteristics in children using cochlear implants (CI) and children using conventional hearing aids (HA). Nine prelingually deaf children using CI and six children with a prelingual severe hearing loss using HA. were selected to participate. Objective (DSI, nasalance scores) as well as subjective assessment techniques (perceptual evaluations) were used, Both the CI and HA children demonstrated normal vocal quality and resonance but showed the presence of articulation disorders, In the CI children, intelligibility was significantly better compared to the HA children. Significantly more phonetic and phonological disorders were present in the HA children. The results of this study show a poorer intelligibility of the HA children in comparison with the CI children which is probably due to the occurrence of significantly more phonetic and phonological disorders, Future detailed analysis in a larger sample of CI and HA children may help further clarify the issue of speech and voice characteristics and may demonstrate an important prognostic value.

AB The Bing test is based on the principle that occlusion of the external auditory meatus improves the perception of bone-conducted sounds unless there is a conductive hearing impairment. An air-bone gap has been reported in patients with large vestibular aqueduct (LVA) syndrome without apparent middle ear dysfunction, We therefore performed the Bing test on nine patients with this syndrome to evaluate whether it is associated with an air-bone gap or middle ear dysfunction. Bone conduction thresholds did not change significantly during the Bing test in any patient. Because an air-bone gap is observed in patients with abnormal communication between the inner ear and cerebrospinal fluid through the LVA, dehiscent superior canal, or dilated inner ear meatus: we propose that a 'three windows' model (in which the abnormal communication provided by the enlarged endolymphatic duct and sac in LVA acts as the 'third window' for sound conductance) might explain the air-bone gap in such patients.

AB The aim of this study was to reassess cochlear dead regions after an interval of twelve months. using the Threshold Equalising Noise (TEN) test. Thirty-four ears of 24 teenagers (mean age of 14 years) with longstanding severe-to-profound sensorineural hearing impairment were tested. Testing was repeated after in interval of 12 months using the same experimental set-up, A total of eight (23.5%) out of 34 cars changed category on retest this decreased to two (7.1%) out of 27 cars when the inconclusive category was removed from the analysis. In both of these ears (of the same participant) the criteria were met at a single frequency, and the masked threshold was only 10 dB above the TEN level per ERBN. When all of the data were examined on a frequency-by-frequency basis the instances that changed category ranged from 15 to 5 The range decreased to between 4 and 34% when the inconclusive category was removed from the analysis.

AB Intended as an input to international standardisation. this study investigated reference hearing thresholds for the calibration of audiometric equipment, which have been determined using 'clicks' as test signals, several kinds of earphones, and two types of transducers (a loudspeaker and a bone vibrator). The threshold measurements were carried out with groups of 25 test persons, with normal hearing capability following as far its possible the ISO-preferred test conditions, The influence of different parameters on the results. such as click duration, polarisation mode, repetition rate, gender and age of the test persons, or type of ear simulator, was studied. The results mainly depend on the type of car simulator used to calibrate corresponding audiometers. Together with the results of another investigation carried out in Denmark, the data of the present study shall form the basis for the coming International Standard ISO 3896 on reference hearing thresholds for acoustic test signals of short duration.

AB The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Mandarin bisyllabic word lists for use in measurement of speech discrimination. Familiar bisyllabic words were digitally recorded by male and female talkers of Standard Mandarin. Percentage of correct word recognition was measured for each word at ten intensity levels (- 5 to 40 dB HL) in 5 dB increments using 20 normally hearing subjects. Using logistic regression, 200 words with the steepest logistic regression slopes were included in four psychometrically equivalent word lists of 50 words each, and eight half-lists of 25 words each. To increase auditory homogeneity of the lists, the intensity of words in each list was digitally adjusted so that the threshold of each list was equal to the midpoint between the mean thresholds of the male and female half-lists, Digital recordings of the psychometrically equivalent word recognition lists are available on compact disc.

AB The aim of this investigation was to develop, digitally record, evaluate, and equate Mandarin trisyllabic words, which could then be used to measure the SRT. A selection of 90 frequently utilized trisyllabic words were digitally recorded by male and female talkers of Standard Mandarin and presented to 20 normally hearing subjects at 13 intensity levels (-10 to 14 dB HL) in 2dB increments. Using logistic regression, psychometric functions were then calculated for all words. Twenty-four trisyllabic, words with steep psychometric function slopes were selected, and their intensities were digitally adjusted to match the mean subject PTA (3.0 dB HL). The mean slopes for the 24 selected male and female trisyllabic Mandarin Chinese words were 11.3 %/dB and 12.1 %/dB, respectively. Thus we developed a list of words which were homogeneous with respect to audibility and slope. Digital recordings of the psychometrically equivalent trisyllabic words are available on compact disc.

DE parents; qualitative; paediatric; cochlear implantation
ID RESIDUAL HEARING; CHILDREN; OUTCOMES
AB The purpose of this study was to understand the parental perspective on paediatric cochlear implantation over time. Face-to-face semi-structured interviews were conducted with 216 families of children who were implanted at the Nottingham Paediatric Cochlear Implant Programme between 1989 and 2002, and who were attending an appointment during the study period (July 2001 August 2002). The qualitative data revealed that time played an important role in family experiences of paediatric cochlear implantation. Expectations were continually revised throughout the process, as a result of new knowledge and new technological developments. The results show that outcomes are highly individualistic although parents had a shared hope of the implant enabling the child to function in a "hearing world"; that the biggest area of contention is in respect of their child's education; and that parents talked openly about constraints imposed on them by implantation. The vast majority of parents did not regret their decision to proceed with implantation.

AB Psychophysical tuning curves (PTCs) can be used to assess the frequency selectivity of the auditory system and to detect and delimit "dead regions" in the cochlea. However, the traditional method for determining PTCs takes too long for use in clinical practice. We evaluated a fast method for determining PTCs, using a band of noise that sweeps in centre frequency and a Bekesy method to adjust the masker level required for threshold. The shapes of the PTCs were similar for the fast and traditional methods, for both normally hearing and hearing-impaired subjects. Rates of change of masker level of 2 dB/s or less gave the most reliable results. A relatively wide bandwidth (20 percent of the signal frequency or 320 Hz, whichever is the smaller) was needed to minimisc the influence of beat detection. When the signal frequency fell within a dead region, the fast method gave PTCs with shifted tips.

AB The objective of the experiment was to investigate three aspects that might contribute to the benefit of fast-acting compression seen in normal-hearing listeners. Six normal-hearing listeners were tested with speech recognition in a fully modulated noise (FUM) either through a fast-acting compressor or through linear amplification. In the first experiment, three different presentation levels of the FUM noise (15, 30, and 45 dB SL) were tested. The second experiment manipulated the control signal of the compressor independently of the audio input signal at four signal-to-noise ratios (-15, -10, -5, and 0 dB). A signal correlated noise version of the speech signal was tested in the third experiment at three speech-to-noise ratios (-20, -15 and -10 dB). Results showed that performance was better with compression than with linear amplification through all of the tested conditions at least when the signal-to-noise ratio was negative. The results suggest that other aspects of the hearing impairment than those simulated here are involved in the degraded performance seen for sonic hearing-impaired listeners with fast-acting compression.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY

DE otoacoustic emission; middle ear; pressure
ID DISORDERS
AB Middle ear pathology has a negative effect on the detectability of otoacoustic emissions.
   In this study, we investigated the effect of compensating a deviant static middle ear pressure while measuring transient evoked otoacoustic emissions (TEOAEs). In 59 children (mean age 4 years, 5 months) TEOAEs were measured twice in one session: first at ambient pressure and than at compensated middle ear pressure.
   On average, TEOAE amplitudes increased by 1.9 dB as a result of middle ear pressure compensation. The amplitude increase was largest in frequency bands centred at I and 2 kHz and a statistically significant correlation was found between the amount of compensated pressure and the TEOAE amplitude increase. In the higher frequency bands centred at 3 and 4 kHz, TEOAE amplitudes were almost insensitive to pressure compensation.
   These results show that measuring OAEs at compensated middle ear pressure enhances the amplitude of TEOAEs, and thus improves the detectability.

AB Two groups of adults, one young and one elderly, were compared on a dichotic task in which continuous speech was monitored for grammatically and semantically anomalous words. Event-related potentials (ERPs) elicited by these anomalies were analyzed in terms of peak amplitude and peak latency of the evoked late-positive component (LPC). Results showed that while LPC peak amplitudes were overall reduced for the group of seniors, LPC peak latencies were similar between both groups of listeners. These findings are consistent with the hypothesis that elderly persons can offset declines in memory, perceptual processes, and speed of mental processing by taking advantage of contextual and prosodic cues in running speech. Additionally, an apparently asymmetric processing negativity was observed in the waveforms of young adults but not seniors. Possible mechanisms include the N400 response to semantic incongruity and a processing negativity component associated with attentional bias toward right hemispace.

AB The present study provides comparative evaluation of the ABR and MLR to 1 kHz brief tones in two groups of hearing-impaired subjects (noise-masked normally-hearing; and sensorineurally hearing-impaired adults), as well as a normally-hearing control group. Tones were presented at intensities from threshold to 80-90 dB nHL. The results of this study show that: (1) the ABR and MLR to these low-frequency (1 kHz) tones are equally accurate in estimating hearing threshold, (2) at suprathreshold levels, there are differences in the ABRs and MLR s for subjects with decreased hearing sensitivity resulting from cochlear pathology, compared to those obtained from adults with simulated hearing loss due to broadband masking, and (3) supra-threshold stimuli produce differential effects on the latency and amplitude characteristics of the ABR and MLR in listeners with true sensorineural hearing impairments. Possible physiologic explanations are offered for this differential pattern of results.

SO INTERNATIONAL JOURNAL OF AUDIOLOGY

DE hearing aid fitting; multi-channel compression
ID LOUDNESS MODEL; SPEECH; AMPLIFICATION; USERS
AB We compared two adaptive procedures for fitting a multichannel compression hearing aid. "Camadapt" uses judgements of the loudness of speech stimuli and the tonal quality of music stimuli. "Eartuner" uses judgements of the loudness and clarity of speech stimuli with differing spectral characteristics. Sixteen new users of hearing aids were fitted unilaterally, using each procedure. The fittings were assigned to Programs I and 2 in the aid, in a counter-balanced order. Subjects kept a diary of their experiences with each program in everyday life. Following 2-4 weeks of experience, they filled in the APHAB and other questionnaires and were re-fitted using both procedures. Camadapt generally led to higher low-level gains and lower high-level gains than Eartuner. Gains recommended by the procedures did not change following experience. Eight subjects preferred the Camadapt fitting and eight preferred the Eartuner fitting. Most subjects gave high overall satisfaction ratings for both procedures. Test-retest reliability was better for Eartuner than for Camadapt. Preference for the Camadapt fitting was associated with slightly better speech communication with Camadapt, while preference for the Eartuner fitting was associated with fewer problems with aversion for that procedure.

ID SPEECH RECEPTION THRESHOLD; INTELLIGIBILITY; LISTENERS; SENTENCES
AB The HINT provides an efficient and reliable method of assessing speech intelligibility in quiet and in noise by using an adaptive strategy to measure speech reception thresholds for sentences, thus avoiding ceiling and floor effects that plague traditional measures performed at fixed presentation levels. A strong need for such a test within the Canadian Francophone population, led us to develop a French version of the HINT. Here we describe the development of this test. The Canadian French version is composed of 240-recorded sentences, equated for intelligibility, and cast into 12 phonemically balanced 20-sentence lists. Average headphone SRTs, measured with 36 adult Canadian Francophone native speakers with normal hearing, were 16.4 dBA in quiet, -3.0 dBA SNR in a 65 dBA noise front condition and -11.4 dBA SNR in a 65 dBA noise side condition. Reliability was established by means of within-subjects standard deviation of repeated SRT measurements over different lists and yielded values of 2.2 and 1.1 dB for the quiet and noise conditions, respectively.

AB The purpose of this study was to evaluate the role and interaction of individual factors on decompensated tinnitus. Subjects consisted of 53 adult patients with chronic tinnitus. They were selected and assigned to two groups, compensated (n =28) and decompensated (n = 25), according to the results of an established tinnitus questionnaire. Both groups were evaluated and compared. The patients with decompensated tinnitus suffered from more pronounced social disabilities, were more prone to depression, and used less effective techniques to cope with their illness. They showed a higher degree of somatic multimorbidity, with particularly strong correlations between tinnitus and the incidence of cardiovascular diseases and hyporacusis. As a consequence, in the psychosomatic tinnitus therapy, greater attention should be given to the treatment of the somatic complaints in addition to psychological and psychosocial aspects.

AB This paper addresses the development and effectiveness of a home education program. The program, designed for hearing-impaired elders and their significant others (SO), deals with communication strategies and speech reading. Participants were randomly assigned to a training group (hearing aid fitting+home education program) or a control group (hearing aid fitting). The training group included 24 hearing-impaired subjects and 24 SO's. Controls were 24 affected individuals and 22 SO's. Questionnaires addressing emotional response, communication strategies and the IOI-HA, IOI-Al and IOI-SO were used. A repeated measures analysis of variance was applied to test group differences between pre, post, and 6-months follow-up measures. Increased awareness of benefits of speech reading and improved interaction with the SO were observed in the training group only (p < 0.05). No group difference on 'emotional response' was found. IOI-Al and IOI-SO demonstrated favorable attitudes towards the program. Follow-up measures showed improved quality of life and satisfaction in the training group, while a decrease was observed among the controls (p < 0.05). Some effects differed between first-time and experienced hearing aid users. Addition of services to amplification and involvement of the SO are relevant in aural rehabilitation.

ID AGE; POPULATION; CONNECTION; VERSION; TRIALS
AB In the present study, the effects of hearing aid use by hearing-impaired older individuals on different aspects of cognitive function, such as memory, attention, executive functioning, and processing speed, were investigated. Fifty-six participants (mean age =72.5) who were fitted with hearing aids were compared with 46 control participants (mean age =74.5) with an equivalent hearing impairment, but who were not fitted with a hearing aid. After a dual baseline measurement and fitting of the hearing aids, all participants were assessed again with neurocognitive tests after 12 months. While the participants with hearing aids had improved aided hearing thresholds, they did not demonstrate an improved performance on the cognitive tests compared to the controls. Thus improved bearing did not improve cognitive functioning. These findings may suggest that hearing aid use only restores impairments at the level of the sensory organ, but does not affect the central nervous system and, as a consequence, cognitive functioning.

AB This paper reports on an evaluation of a structured group therapy intervention for adult cochlear implant (CI) recipients designed to improve overall communication and coping skills. 33 adult CI recipients (14 males, 19 females: mean age 61; 1 - 14 years since CI) participated in a 2-day structured group therapy intervention with a follow-up session 4 weeks later. Measures were: communication behaviors (CPHI). assertiveness (Rathus), depression (DASS), and behavior during conversation (Dyalog). TCI personality traits were utilized as predictors of change. Repeated measures analyses showed that participants demonstrated significant improvements on measures of assertiveness, emotional well-being, and coping behaviors at 3 months post-intervention that persisted at a 12-month follow-up. Several personality traits predicted change. Although subjects had presumably adapted to their cochlear implants and had learned communication strategies in hearing rehabilitation programs, the improvements on several measures suggest that a structured group therapy intervention can enhance outcome following cochlear implantation.

AB The performance of an experimental frequency compression hearing device was evaluated using tests of speech understanding in quiet. The device compressed frequencies above a programmable cut-off, resulting in those parts of the input signal being shifted to lower frequencies. Below the cut-off, signals were amplified without frequency shifting. Subjects were experienced hearing aid users with moderate-to-severe sensorineural hearing loss and sloping audiograms. Their recognition of monosyllabic words was tested using the experimental device in comparison with conventional hearing aids. Of the 17 subjects, eight showed a significant score improvement (p < 0.05), whereas one subject showed a significant score decrease. Some of the improvements may have resulted from the better audibility provided in the high frequencies by the experimental device in comparison with the conventional aids. However, a subsequent study found that increasing the high-frequency gain in the conventional aids did not produce equivalent perceptual benefits.

TI Manufacturer predicted and measured REAR values in adult hearing aid
   fitting: Accuracy and clinical usefulness
SO INTERNATIONAL JOURNAL OF AUDIOLOGY

DT Article
DE real-ear measures; real-ear aided response; hearing aid fitting;
   verification; adult
AB Audiologists may fit hearing aids using real-ear aided response (REAR) values predicted by manufacturer's fitting software, rather than actual measured REARs. This study examined how well one manufacturer's software was able to predict REARs for a DSP behind-the-ear product in 41 adults (N =79 ears) under four conditions (two hearing loss configurations and two inputs). Results showed that for all ears tested, measured REAR values were significantly different from predicted for most of the audiometric frequencies for all four test conditions. Discrepancies between measured and predicted REAR values were greater in males' ears than females'. Few ears' REAR values (<= 12%) were judged to be clinically similar to predicted. Results suggest audiologists should consider using individual real-car measures in adult hearing aid fittings until manufacturer software is shown to accurately predict real-ear hearing aid performance.

AB The effect of air pressure change on bone conduction (BC) hearing thresholds in the occluded ear was investigated. The pump manometer system of an impedance bridge was used to change the air pressure in the ear canal of twenty-two normally hearing subjects. BC thresholds were measured with: (1) open ear; (2) the ear canal occluded with a probe tube and application of 0 daPa air pressure; and (3) the ear canal occluded with a probe tube and application of -350 daPa air pressure. Thresholds were lower in condition 2 than in condition 1, the difference decreasing from 27 dB at 2500 Hz to 4.5 dB at 2000 Hz. Thresholds were higher in condition 3 than in condition 2. The results are interpreted in terms of changes in the relative contribution of the three routes of transmission for BC sound produced by occlusion and by a static pressure difference.

AB The aims were to compare the genotype/phenotype relationship between USH3 mutations and the consequent hearing and vestibular phenotype; and to compare hearing loss (HL) progression between Usher syndrome types IB, IIA and USH3. Genetic, audiometric and vestibular examinations were performed in 28 subjects with USH3. Five different mutations in USH3 were identified. Severe HL was present from an early age (4 to 6 years) in 35% of subjects with USH3. Progression of HL begins in the first decade, and approximately 50%, of subjects with USH3 become profoundly deaf by age 40, Various vestibular abnormalities were found in about half (10/22) of the tested subjects with USH3. Depending on the severity of HL, subjects with USH3 might be misdiagnosed as either Usher type 113 or IIA. The results from this study can be used as discriminatory features in differential diagnosis of this syndrome.

ID MENIERES-DISEASE; MIGRAINE; FEATURES
AB The purpose of this study was to determine the prevalence of reduced or absent labyrinthine reactivity (vestibulopathy) in two groups of participants with posterior canal BPPV. One group had prior diagnosis of otologic disease (positive history group). No one in the second group had ever been diagnosed with otologic disease (negative history group). Caloric responses were retrospectively analyzed for the two groups. Patients with a positive history exhibited a greater prevalence of vestibulopathy than patients with a negative history. The positive history group, on average, also exhibited a larger unilateral weakness than those patients in the negative history group. We conclude that patients with BPPV and a history of otologic disease are more likely to present with vestibulopathy, than patients with BPPV and no history of otologic disease. This finding supports the benefit of complete vestibular evaluation in patients with BPPV to ensure comprehensive and successful treatment outcome.

TI Couples' attributions about behaviours modulated by hearing impairment:
   Links with relationship satisfaction
SO INTERNATIONAL JOURNAL OF AUDIOLOGY
LA English
DT Article
ID MARRIAGE; PERSPECTIVE; EXPERIENCES; IMPACT
AB The aim of the study was to examine the link between the nature of attributions made by partners about behaviours modulated by hearing loss, and overall relationship satisfaction. Forty-three hearing-impaired males and 23 hearing-impaired females together with their partners, each rated the hearing-impaired person's hearing ability, their own relationship satisfaction, and their attributions for hypothetical behaviours typically associated with impaired hearing. Attributions covered perceived causes of behaviour and perceived responsibility. The extent to which the behaviours typically associated with impaired hearing, were attributed to personal causes and responsibilities was inversely correlated with relationship satisfaction. Female partners (more than male partners, or females with impaired hearing) made attributions that accentuated the unpleasant implications of behaviour. Where attributions and ratings of degree of hearing loss were greater in partners than in the person with the loss, relationship satisfaction was lower. Implications for rehabilitation Counselling are discussed.

ID ADULTS
AB The objective of the study was to investigate the effects of a family history of hearing impairment on those people with the hearing impairment themselves. The subjects were 102 consecutive patients with a family history of hearing impairment, seen in an audiological rehabilitation clinic. Each was given an open-ended questionnaire asking whether such a family history had any effects on them and, if so, to list any effects. Results were qualitatively analysed. 57 subjects indicated effects. Of those listed, 57% were positive, 19% negative, and 24% neutral. The most common positive effects concerned realising the importance of hearing aids and early help-seeking. Common negative effects were concern for the future of themselves and their children. Neutral effects were a reported ignorance or denial of a family history. The results emphasize the importance of asking patients about any family history when planning their rehabilitative programme.

AB This paper presents normative data of hearing threshold levels of a population screened with various criteria, as compared to unscreened population data. Computer-controlled pure-tone audiometry was administered to the adult population in Nord-Trondelag County, Norway, during 1995-1997. The 51 975 participants also provided questionnaire information about occupational and leisure noise exposure, previous car infections, and head injury. While screening had little effect on the median hearing threshold levels of young adults, there was a substantial effect when screening men above 40 years of age for a history of noise exposure. Screening for known ear-related disorders and diseases resulted in small effects on the mean hearing threshold levels. The median hearing thresholds of both the screened and the unscreened sample exceeded the age and sex specific thresholds specified by the ISO 7029.

DE personal stereo players; noise injury; hearing loss
ID DAMAGE
AB Hearing healthcare professionals often express concern about the possible increased risk of noise injury, and potential for subsequent hearing loss that may result from the rise in the use of personal stereo players (PSP) in the community. Measurements were made of a sample of 55 individuals who were using a PSP as part of their daily activity, for example commuting to work, in what could be considered noisy backgrounds. Thus measurements could be considered to exemplify the worst-case conditions. The average, A-weighted, eight-hour equivalent, continuous noise exposure level was determined to be 79.8 dB, with a statistically significant difference between males and females, of 80.6 dB and 75.3 dB respectively. There was no correlation between self-reported hearing loss and/or the incidence of tinnitus. The noise exposure results obtained did not indicate that there was a significant increase in the risk to potential noise injury from PSP use alone.

DE distortion product otoacoustic emissions; ultrasonic frequency; rodents;

ID HEARING
AB The aim of this work has been to construct and evaluate a system for recording distortion product otoacoustic emissions in rats at ultrasonic frequencies up to at least 50 kHz. The paper primarily describes the design of the acoustic probe system, as this is the most critical part. An acoustic ear simulator was developed and used for the subsequent calibration of the stimulus signals. A detachable probe system was provided in order to allow for visual inspection of the probe fitting in the ear canal prior to the final placement of the acoustic probe.
   Test/retest performance was evaluated by comparing DP-grams and I/O curves in 12 anaesthetized Wistar rats in two sessions separated approximately by one week. The between subject variance of the 12 tested rats appeared to be very modest, thus making the setup suitable for testing, for instance, ototoxicity of drugs or detection of cochlear damage due to noise exposures in rodents.

AB Two approaches to assess auditory steady-state responses (ASSR) are compared under similar test conditions: a monaural single-frequency technique with a detection method based on phase coherence (AUDERA), and a binaural multiple-frequency technique using the F-test (MASTER). ASSR thresholds at four frequencies were assessed with both methods in both ears of ten normal-hearing and ten hearing-impaired adult subjects, within a test duration of one hour. The test-retest reliability and the influence of prolonging the test duration are assessed. For the total subject group the multiple-frequency technique outperforms the single-frequency technique. In hearing-impaired subjects, however, both techniques perform equally well. Hearing thresholds can be estimated with a standard error of the estimate between 7 and 12 dB dependent on frequency. About 55% of the estimates are within 5 dB of the behavioral hearing threshold, and 94% within 15 dB. Prolonging the test duration improves the performance of both techniques.

AB Cognitive tests of speech understanding were administered (presented as text, or in auditory or audiovisual modality) and perceived effort was rated. This was done in four background conditions: in silence, and in three types of noise (S/N = +10 dB) varying in temporal structure and meaningfulness. Four groups of 12 subjects each (young/elderly with normal hearing and young/elderly with hearing impairment) participated. The presence of noise had a negative effect on accuracy and speed of performance in the speech processing tasks, and resulted in higher scores of perceived effort, even when the stimuli were presented as text, Differences in performance between noise conditions existed. In the Subjective scores, the noise with temporal variations, but without meaningful content, was the most disruptive of the three noise conditions. In the objective scores, the hearing-impaired subjects showed poorer results in noise with temporal variations. The elderly subjects were more distracted by noise with temporal variations, and especially by noise with meaningful content. In noise, all subjects, particularly those with impaired hearing, were more dependent upon visual cues than in the quiet condition.

AB Speech intelligibility measurements strongly depend on several procedural parameters. In order to obtain comparable results from different test procedures, these parameters must be investigated as to which should be standardized and which could be set freely. This study investigates the influence of noise level. noise type, and presentation mode on speech reception thresholds (SRTs), and intelligibility function slopes in noise for normal-hearing and hearing-impaired subjects. The noise presentation level had no significant influence on either SRTs or slope values, provided that the presentation level exceeded hearing threshold. Two stationary, speech-shaped noises produced identical results. Speech-simulating fluctuating noise yielded about 14 dB lower SRTs for normal-hearing subjects and about 10 dB lower SRTs for 20% of the hearing-impaired subjects. Of the hearing-impaired subjects, 30% did not benefit from the modulations and showed similar SRTs as for stationary noise. Using continuous noise yielded lower SRTs compared to gated noise. However, the difference between the results in continuous and gated noise was not significant for the hearing-impaired subjects. A presentation level of 65 dB SPL (normal-hearing subjects) or 80 dB SPL (hearing-impaired subjects) and an interfering noise with a spectrum similar to the mean long-term average speech spectrum (LTASS) is suggested for comparable adaptive measurement procedures. A fluctuating, speech-shaped noise is recommended to differentiate between subjects.

AB The purpose of this study was to compare the quality of life of hearing-impaired adults. as assessed by three different utility measures - the EuroQol (EQ-5D), the Health Utilities Index Mark III (HU13), and the SF-6D (derived from the SF-36 questionnaire). Measuring quality of life in terms of utility enables the benefits of many interventions to be compared on a common scale, where 0 corresponds to death and 1 to perfect health. Utility scores for 915 new referrals (mean age 69 years, 55% male) to four UK audiology clinics were estimated, The mean utility scores on the EQ-5D (0.79), SF-6D (0.77), and HU13 (0.56) were all significantly different from each other. The agreement between measures was most commonly moderate according to the intra-class correlation coefficient (ICC = 0.36 to 0.58). This suggests that different utility measures will provide different estimates of the effectiveness of hearing aid provision.

AB This study aimed to reveal in general population the prevalence, associations, and statistical model of recurrent tinnitus by means of a mailed questionnaire. The study sample consisted of 1720 randomly selected adults who were classified into three subgroups: recurrent (once a month or more often), occasional (less often than once a month), and no tinnitus. According to age and gender standardized prevalence, recurrent tinnitus was reported in 15% of the sample. It was statistically highly significantly associated with earache, fullness of ears, shoulder pain, the 25-years age group, and visits to a physician. The strongest predictor of recurrent tinnitus was fullness of ears followed by earache, shoulder ache, and temporomandibular disorder pain. We conclude that recurrent tinnitus seems to be quite common in adults and associated with earache and fullness of ears. In patients with tinnitus without clinical findings, the examination of the stomatognathic system and cervical spine is recommended.

AB The purpose of this study was to characterise two new mouse mutants, carousel, and whirligig. Both were derived from a large-scale mutagenesis programme which screened for dominantly inherited mutations that cause hearing impairments and balance defects. Genetic mapping placed both mutations on the proximal region of chromosome 4. Paint-filling and clearing techniques revealed abnormalities of the lateral semicircular canal. Scanning electron microscopy showed increased numbers of outer and inner hair cells in the apical region of the organ of Corti. The behavioural, genetic, and morphological characteristics lead us to the conclusion that both mutants are probably alleles of seven previously identified mutants which all map to proximal chromosome 4 and share similar defects of the lateral semicircular canal, We suggest that this region may be particularly susceptible to ENU mutagenesis independent of genetic background.

   LOCALIZATION; EAR; AMPLIFICATION
AB The benefit of a bone-anchored hearing aid (BAHA) to a patient fitted bilaterally; and the benefit of a BAHA(&REG;) to a unilaterally deaf person was estimated by four acoustical measurements: directional sensitivity of a BAHA(&REG;) placed at the skull, vibration transmission in the skull, gain, and estimated transcranial attenuation of bone conducted sound. Provided a patient has a similar bone conduction hearing ability at both cochlea, it was found that a patient should, theoretically, benefit from bilateral fitting of BAHAs in terms of better hearing thresholds from the front, and better overall hearing ability from the surround. The data indicates further, that bilateral fitting facilitates extraction of interaural cues, which should lead to greater ability to determine the direction of a sound source, as well as better hearing in noise. However, due to the cross-hearing of bone conducted sound, the binaural processing for the patient fitted bilaterally with BAHAs is less than for normal binaural air conduction hearing. Finally, the data showed that the benefit of fitting a BAHA(&REG;) in a unilaterally deaf person, depends on that person's transcranial attenuation.

AB This interdisciplinary long-term study examined the effects of recreational noise exposure on the hearing of adolescents. Boys and girls (aged 14-17 years) were examined during a four-year period. Audiological, psychosocial, and sound measurements were performed yearly to determine the hearing threshold level (HTL) of participants in the 250-16000 Hz range, their participation in recreational activities, and the sound levels at discos and through personal music player use. A tendency of the mean HTL to increase in both genders during the study was observed, especially at 14000 Hz and 16 000 Hz. Boys had a higher mean HTL than girls. The participation in musical activities increased yearly, 'attendance at discos' being the favourite musical activity for both groups. In general, boys were more exposed to high sound levels than girls. The equivalent sound levels in discos ranged between 104.3 and 112.4 dBA, and between 75 and 105 dBA from personal music players.

AB Part II, continuation of a previous paper, describes the significant hearing threshold shift found during the third year of the long-term study, which continued to be present in the fourth year. in a number of adolescents classified as Subgroup 2, who showed a higher mean HTL in the middle and especially in the high frequency ranges than the rest of the studied adolescents, classified as Subgroup 1. In both subgroups. the subjects showed high participation in recreational activities: nevertheless, the adolescents in Subgroup 2 showed higher participation in some of them in the last year of the study. From the beginning of the study, the mean HTL of the adolescents in Subgroup 2 was higher than the mean HTL of the adolescents in Subgroup 1. The exposure to high sound levels during leisure activities can be a cause of permanent hearing damage among young people with 'tender ears'.

AB The objectives of the present study were to evaluate both the respective and combined effects of occupational noise exposure and smoking on hearing, taking age into consideration. The evaluation was conducted using 1478 subjects without a history of ear disease out of a population-based sample of 2267 adults, aged 40-79 years. Pure-tone audiometry and a questionnaire were administered. A deleterious effect of noise exposure on hearing was significantly observed in both genders at many frequencies after adjustment for age, income, and education. The smoking habit alone significantly affected hearing deterioration at 4000 Hz in noise-unexposed males. The combined effect of noise and smoking was not interactive but additive. A dose-response effect of smoking on hearing loss was observed in middle-aged males without noise exposure. Smoking and noise exposure were associated with hearing loss respectively. This result is noteworthy for the preservation of good hearing especially at the beginning of aging.

AB The time course of changes in perceived sound quality after hearing instrument fitting has not been studied systematically. It is possible, for example, that patients may object to additional high frequency gain when fitted, but not after a period of auditory acclimatisation. The aim of this study was to utilise sound quality judgements to compare two frequency responses in new users at 4-week intervals over a 24-week post-fitting period. The null hypothesis was that there would be no change in sound quality judgements over time. A total of 16 elderly subjects were fitted monaurally with the same model of linear. programmable hearing instrument. This was set to a standard response that provided 26-29 dB of real-ear insertion gain at 2000-4000 Hz. This program was worn by the subjects for the duration of the study. All subjects reported greater than four hours of daily use. The alternative response which was used in a paired comparison paradigm. provided a mean gain reduction of 3, 8. 13, and 16 dB at 2000, 3000, 4000 and 6000 Hz, respectively. Subjects compared the standard and the alternative responses for sound quality along dimensions of comfort, clarity, and overall preference while listening to running speech presented in quiet, steady noise. and speech babble. At the time of fitting there was a small preference for the standard response when judging clarity, but the alternative response was preferred for comfort and preferred overall. Repeated-measures analysis of variance (ANOVA) for each quality dimension did not reveal any statistically significant change over time. It is concluded that this pattern of preference is unaffected by acclimatisation to amplification. at least over the initial 24 weeks of instrument use.

AB The German translation of the International Outcome Inventory for Hearing Aids (IOI-HA) was used in a variety of studies including a retrospective mailing campaign and three field tests on recently launched hearing aids. The psychometric properties were compared with each other and with results of previous studies in the USA, Wales, and the Netherlands. Like the English and the Dutch version, the German IOI-HA showed high internal consistency, and factor analyses as well as inter-item correlations indicated the existence of a two-dimensional scale. Furthermore, the IOI turned out to be a valid instrument for distinguishing satisfied and non-satisfied customers during the trial period of a hearing aid.

AB Sequential application of a statistical test is usually applied in an automated auditory response detection algorithm. The sequential test strategy is very time-efficient but increases the probability of a false rejection of the null-hypothesis. For this reason. it is necessary to correct the critical test value. However, the well-known Bonferroni correction leads to an over-correction when dealing with dependent or partly dependent data. The objective of the study reported here was to develop a method to determine the critical test value for the sequential testing of dependent data. Extensive Monte Carlo simulations were used to develop this method. The simulation results were reviewed and the benefit of the suggested method, in comparison to the Bonferroni correction, was shown using a large sample of real amplitude modulation following response data. The detection rate determined for these data and the ROC curve demonstrate the advantage of using the method suggested here.

AB The dynamics of contralateral acoustic suppression were studied using real time (millisecond resolution) distortion product otoacoustic emissions (DPOAEs) in chinchillas and humans. Latency of DPOAE suppression onset is 26 ins in chinchillas and 45 ms in humans. After onset, suppression builds over time before tending to plateau, reflecting a temporal integration process with a time constant of 100 ms (chinchillas). In chinchillas, suppression persists for 40 ms even when elicited by stimuli as short as 5 ms With stimuli &GT; 40 ms, offset and onset latencies are similar and duration of suppression equals that of the contralateral stimulus. A comparison of DPOAE suppression onset latency with neural latency data from the pathways involved suggests the following timing scheme: stimulus onset to activity in (ventral) cochlear nucleus. 4 ms (15% of delay); transfer to olivocochlear efferents, 9 ms (35%); efferent conduction to presynaptic OHC site, 4 ms (15%): synaptic and mechanical events at OHCs, 9 ms (35% of delay).

AB The aim of the study was to assess the effects of exposure to impulse noise on TEOAE, as compared to PTA. The study comprised 92 soldiers, subjected to impulse noise during military service. The control group consisted of secondary school students, not exposed to noise. Extended high frequency PTA, and TEOAE were recorded before and after one year of military service. The total level of noise and spectrum analysis were performed for all kinds of weapons, separately.
   The highest levels of noise for weapons were related to frequencies from 1.6-16 kHz. After military service significant deterioration of hearing was observed on average by 6 dB exclusively at the frequencies of 10 and 12 kHz. TEOAE reduction was registered predominantly at frequencies of 2, 3 and 4 kHz, with the greatest decrease at 2 kHz (p < 0.02). The control group did not show any significant audiometric changes as well as TEOAE during the time of experiment.

AB The present study investigated body position effects on transient evoked otoacoustic emission (TEOAE) recordings of clinical significance. Sixty adults (30 males, 30 females) were assessed using the Otodynamics ILO88 Analyzer in three positions (sitting, supine, and side-lying). Results indicated significant positional effects on the TEOAE parameters of A-B difference, noise, whole wave reproducibility, and response levels. These differences included higher noise levels in supine and side-lying positions in comparison to the upright sitting position. Lower whole wave reproducibility measurements, and higher response amplitudes, in the side-lying position compared with supine and seated positions were also observed. No significant effects were evident for signal-to-noise ratio or band reproducibility. Given the lack of significant body position effects on these latter parameters and the infrequent clinical use of the other parameters in isolation, there was no evidence to suggest the future need for major review of current pass/fail criteria or of the standard test protocol.

AB This study aims to describe the association between otoacoustic emissions (OAEs) and pure-tone hearing thresholds (PTTs) in an unscreened adult population (N =6415), to determine the efficiency by which TEOAEs and DPOAEs can identify ears with elevated PTTs, and to investigate whether a combination of DPOAE and TEOAE responses improves this performance. Associations were examined by linear regression analysis and ANOVA. Test performance was assessed by receiver operator characteristic (ROC) curves. The relation between OAEs and PTTs appeared curvilinear with a moderate degree of non-linearity. Combining DPOAEs and TEOAEs improved performance. Test performance depended on the cut-off thresholds defining elevated PTTs with optimal values between 25 and 45 dB HL, depending on frequency and type of OAE measure. The unique constitution of the present large sample, which reflects the general adult population, makes these results applicable to population-based studies and screening programs.

AB The relationship between hearing sensitivity in the extended high-frequency region (8-16 kHz) and (1) the presence of synchronized spontaneous otoacoustic emissions (SSOAEs) and (2) the strength of click-evoked and distortion product otoacoustic emissions (CEOAEs and DPOAEs) was investigated in 104 ears of 57 young adults. The age range was confined to 16 to 19 years. All subjects had normal hearing in the conventional audiometric frequency range (0.5-8 kHz). Ears with detected SSOAEs had better hearing sensitivity in the extended high-frequency region and also higher levels of CEOAEs and DPOAEs than cars with undetected SSOAEs. The results support the hypothesis that the presence of SSOAEs is indicative of an car with highly normal cochlear function over a broad frequency range.

AB Clinical procedures related to patients with Alzheimer's Disease (AD) largely fail to address the patient's hearing. Given the challenges of this population, unconventional indicators of treatment efficacy may be required. Palmer et al (1999) reported on caregiver-tracked behaviors as outcome measures for hearing aid intervention. Using these data, hearing aid use and subsequent behavior was modeled as a first-order dynamic system, characterized by responses following an exponential time course. The results of such modeling suggest predictable outcomes of hearing aid intervention, or at least useful parameters of quantification (e.g. time-constant and steady-state response), permitting critical assessment of effects of intervention on negative behaviors versus hearing aid use, comparisons among behaviors, and/or comparisons of hearing-aid-use patterns and behavior counts among patients. Use in this and other difficult-to-test populations warrant further study to evaluate clinical efficacy of the analysis described.

AB The purpose of the present study was to examine possible signs of long-term cognitive and/or central auditory sequelae seven to eleven years after a closed head injury (CHI) of sufficient severity to cause scull fracture and/or brain contusion. Another purpose was that this investigation should be carried out in a group of recovered trauma victims with, to the individual, no known or minimal sequelae.
   A computer-based set of five cognitive tests and three central auditory tests were used in a group of formerly brain-injured patients who considered themselves as well recovered. Most of the participants did not report any signs of cognitive or auditory impairment. Tests of working memory capacity, verbal information processing speed, phonological processing and verbal inference-making ability were used. Auditory brain response (ABR), distorted speech audiometry (interrupted speech), and phase audiometry were used to test central auditory function. The initial severity of brain damage, i.e. status when the patient arrived at the emergency ward, was estimated with Swedish Reaction Level Scale (RLS).
   Cognitive shortcomings after CHI were demonstrated in a high percentage (59%, 13/22) of the cases seven to eleven years after the injury. Central auditory processing disorders (APD) were also demonstrated in a fairly high percentage (58%, 11/19) of the subjects. None of the correlations between RLS and the results on cognitive and central auditory tests reached statistical significance. However, there was a correlation between cognitive performance and the results on the central auditory tests used in this investigation. Eighty percent (8/10) of those participants with pathologies on ABR and/or phase audiometry and/or IS also failed on one or more of the cognitive tasks, compared to 44% (4/9) among those with no signs of APD.
   It is possible, many years after CHI, to observe cognitive shortcomings and APD in a relatively high percentage of CHI cases that are subjectively considered to be fairly well recovered. The cognitive tasks used in the study have proved to be a sensitive method to discover cognitive impairments. Long-term cognitive sequelae and APD could not be predicted from RLS scores.

ID THERAPY
AB This study retrospectively analysed how 20 patients with posterior canal benign paroxysmal positional vertigo (BPPV) were managed from primary care, to treatment in tertiary care. The average time from first referral to treatment was 93 weeks, with an average of 58 weeks within primary care and 40 weeks within hospital care. At least 85% of cases had classical symptoms of BPPV and could have been easily identified by Primary Care Physicians at first referral, had they been trained to recognise and diagnose the condition. It was concluded that patients could be treated more efficiently and at less cost if the condition was identified at first referral in primary care, and treated in either primary care or dedicated BPPV clinics receiving referrals from primary care. A dedicated clinic for BPPV is recommended, which will substantially reduce waiting time for treatment and save primary care and hospitals time and money by avoiding unnecessary appointments and medication.

AB The primary aim of the study was to determine the effect of altering channel stimulation rate on the performance of adult cochlear implant users. Six adult users of the Med-El CIS processing strategy underwent tests of categorical identification of synthetic speech, tests of sentence recognition and tests of consonant recognition in three listening conditions: high channel stimulation rate (ranging from 1500 to 2020 pps/ch), a medium rate (800 pps/ch) and a low rate (400 pps/ch). Number of channels was held constant across rate conditions. With the categorical identification task, performance varied by acoustic cue type but did not vary with rate. With the consonant recognition task performance varied by phonological feature, but there was also no significant effect of rate. However, two subjects showed markedly reduced sentence scores at lower rates. Results suggests that higher stimulation rates with the CIS strategy may be beneficial to speech perception in some cases.
