A battery of tests for fitting hearing aid to singlesided deafness client – a case report

Abstract

For a patient with single-sided deafness (SSD), it was observed that a hearing aid programmedto unmasked thresholds resulted in no intolerance to amplified speech and eliminated a sensa-tion of vibration. Further, the binaural advantage was assessed using localization and speech innoise tests and the programmed settings were found to be beneficial in the aided conditioncompared to the unaided condition. Further, the hearing aid trial was performed using a pairedcomparison method by occluding the better ear with an otoblock and speech noise was deliv-ered using insert earphone at 65 dB SPL. The aided benefit in each hearing aid was best whenoccluding the better ear with an otoblock. But the findings indeed require further systematicdesign on a cohort of SSD before coming into concluding remark.
