摘　　要：目的:研究多频听觉稳态反应(ASSR)、短纯音听觉脑干诱发电位(Tb-ABR)和短声听觉脑干诱发电位(c-ABR)反应阈与纯音听阈(PTA)在正常听力人群中的差别和相关性。方法:对正常听力的受试者(共58耳)进行ASSR、Tb-ABR和c-ABR以及纯音测听检查,分别得出前三者测试的反应阈并与PTA进行相关性分析。结果:ASSR和Tb-ABR的反应阈均与同频率的PTA具有良好的相关性;Tb-ABR的反应阈与PTA的值接近,ASSR反应阈与PTA间的差值较大;c-ABR与PTA2、4kHz听阈的均值呈线性相关。结论:ASSR和Tb-ABR都是较好的评估行为听阈的频率特异性客观测听方法,Tb-ABR结合c-ABR能较好地反映PTA。Objective：To evaluate the accuracy with which auditory steady-state response （ASSR）, tone burst auditory brain stem response （Tb ABR） and click-evoked auditory brainstem response （c-ABR） thresholds predict behavioral thresholds, using a within-subjects design. Method：ASSR, Tb-ABR and c-ABR thresholds were recorded in a group of adults with normal hearing （58 ears）. Evoked-potential thresholds were recorded and compared with behavioral, pure-tone thresholds. Result：The results suggested both ASSR and Tb-ABR thresholds had high correlations to pure-tone thresholds. Tb-ABR thresholds were recorded much closer to behavioral threshold than ASSR thresholds. There was a linear relation between c-ABR thresholds and average thresholds of 2 kHz, 4 kHz pure tone audiometry. Conclusion： Both the ABR and the ASSR provided reasonably accurate predictions of multi-frequencies behavioral threshold. Tb-ABR combined with c-ABR may take the accuracy predicted behavioral threshold.
