Abstract

Recordings of pure tone response, 40 Hz auditory event-related potential (40 Hz AERP) and auditory brainstem response (ABR) were obtained for 74 ears of 42 cases (32 normal ears, 42 injured ears). 40 Hz AERP (0.5-2 kHz) of 20 ears was tested under natural sleep and awake conditions. The results showed that the threshold of 40 Hz AERP was higher than that of tone pip, with the difference of 12.7 +/- 6.4 dBnHL at 0.5 kHz, 14.7 +/- 6.3 dBnHL at 1 kHz, and 15.6 +/- 5.6 dBnHL at 2 kHz respectively. The threshold of 40 Hz AERP increased in natural sleep compared with that in awake state. The threshold of ABR was higher than the behavioral. The data suggests that jointly using several tests get more accurate and objective results in evaluating hearing loss.

摘要

对42例患者的74只耳（32只正常耳，42只损伤耳）进行了纯音反应、40赫兹听觉事件相关电位（40 Hz AERP）和听觉脑干反应（ABR）记录。对20只耳的40 Hz AERP（0.5 - 2 kHz）在自然睡眠和清醒状态下进行了测试。结果显示，40 Hz AERP的阈值高于短声，在0.5 kHz时相差12.7±6.4 dBnHL，在1 kHz时相差14.7±6.3 dBnHL，在2 kHz时相差15.6±5.6 dBnHL。与清醒状态相比，40 Hz AERP的阈值在自然睡眠时升高。ABR的阈值高于行为测听阈值。数据表明，联合使用多种测试在评估听力损失时可获得更准确和客观的结果。
