摘要： 目的通过对受检者听性稳态反应(auditory steady-state response,ASSR)与40Hz听觉相关电位(auditory event related potential,AERP)测试结果的比较分析,探讨ASSR与AERP评估听阈的准确性及其在法医临床鉴定中的应用。方法对受检的37耳分别进行纯音测听(pure tone audiometry,PTA)、ASSR和40HzAERP测试。ASSR和40HzAERP测试均在清醒状态下进行。结果ASSR和40HzAERP反应阈均与纯音听阈具有良好的相关性,且阈值均高于纯音听阈;ASSR与40HzAERP反应阈对纯音听阈的评估差异无统计学意义。结论确定合理的校正值后,ASSR可以用于行为听阈的客观评估。

Abstract: Objective 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. Methods Thirty seven ears were tested with pure-tone audiometer, 40 Hz AERP and ASSR, respectively. All the volunteers in our study were awake during 40 Hz AERP test and ASSR test. Results Thresholds acquired with ASSR and 40 Hz 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 40 Hz AERP in estimating pure-tone thresholds. Conclusion After determining the correct value, ASSR can be used directly to evaluate hearing loss objectively.
