Abstract

The usefulness of 80-Hz amplitude-modulation following response (AMFR) detected by phase spectral analysis to predict the hearing threshold during sleep was evaluated in 20 normal adults, 8 normal children and 37 children with hearing impairment. The onset effect of tonal stimulus on 80-Hz steady state response was studied in normal adults during sleep and a threshold of 80-Hz AMFR detected by phase spectral analysis was compared with that of ABR elicited by tone pips in children during sleep. Although 80-Hz AMFR is not appropriate for the assessment of hearing in adults, it appears useful for evaluating hearing in young children during sleep. Hearing prediction by 80-Hz AMFR appears to be more accurate than that by ABR elicited with tone pips. The onset effect of stimulus on 80-Hz AMFR with modulation depth of 95% was less than 80-Hz SSR evoked by clicks.

摘要

通过相位谱分析检测的80赫兹调幅跟随反应（AMFR）在预测睡眠期间听力阈值方面的有用性，在20名正常成年人、8名正常儿童和37名听力受损儿童中进行了评估。在睡眠期间对正常成年人研究了音调刺激对80赫兹稳态反应的起始效应，并将通过相位谱分析检测的80赫兹AMFR阈值与睡眠期间儿童由短纯音诱发的ABR阈值进行了比较。虽然80赫兹AMFR不适用于评估成年人的听力，但它似乎对评估幼儿睡眠期间的听力有用。通过80赫兹AMFR进行的听力预测似乎比用短纯音诱发的ABR更准确。调制深度为95%时刺激对80赫兹AMFR的起始效应小于点击诱发的80赫兹稳态反应（SSR）。
