To compare the results between auditory steady-state response (ASSR) and 40 Hz auditory event related potential (AERP), and explore the accuracy of hearing thresholds by using ASSR and AERP and the clinic forensic value.
Thirty seven ears were tested with pure-tone audiometer, 40Hz AERP and ASSR, respectively. All the volunteers in our study were awake during 40 Hz AERP test and ASSR test.
Thresholds acquired with ASSR and 40Hz AERP test had a close correlativity and showed higher than those acquired with PTA test. There was no significant difference between the accuracy of ASSR and 40Hz AERP in estimating pure-tone thresholds.
After determining the correct value, ASSR can be used directly to evaluate hearing loss objectively.
比较听觉稳态反应(ASSR)与40赫兹听觉事件相关电位(AERP)的检测结果,探讨ASSR和AERP测听阈值的准确性及临床法医学价值。
对37只耳分别进行纯音听力计、40赫兹AERP及ASSR检测。本研究所有志愿者在40赫兹AERP检测及ASSR检测过程中均保持清醒。
ASSR和40赫兹AERP检测所得阈值具有密切相关性,且高于纯音听力检测所得阈值。ASSR和40赫兹AERP在估计纯音阈值方面的准确性无显著差异。
在确定正确值后,ASSR可直接用于客观评估听力损失。
