Abstract

Cortical evoked response audiometry (CERA) has been used to identify the presence of a non-organic component in cases where compensation for hearing disability is claimed. This study aims at verifying the magnitude of discrepancy between thresholds estimated by CERA and by pure-tone audiometry (PTA). Results from 204 claimants (408 ears) with reliable PTA and CERA records showed mean discrepancy values between PTA and CERAT of less than 5 dB at high frequencies. Over 83.2% of claimants had a CERAT and PTA threshold discrepancy within 10 dB. Results suggested that while CERA threshold measurement could not accurately predict PTA in all cases, it could still be used as an objective guideline to rule out the presence of a non-organic component in hearing disability compensation claimants.

摘要

皮质诱发反应测听法（CERA）已被用于在有人声称因听力残疾而要求赔偿的案例中识别非器质性成分的存在。本研究旨在验证CERA估计的阈值与纯音听力测定法（PTA）估计的阈值之间的差异程度。204名索赔者（408只耳朵）的PTA和CERA记录可靠，结果显示高频时PTA和CERA T之间的平均差异值小于5分贝。超过83.2%的索赔者CERA T和PTA阈值差异在10分贝以内。结果表明，虽然CERA阈值测量不能在所有情况下准确预测PTA，但它仍可作为一项客观指南，以排除听力残疾赔偿索赔者中存在非器质性成分的情况。
