OBJECTIVE To find the best way to evaluate the hearing threshold with the objectivethresholds of auditory brainstem response(ABR) and 40Hz auditory event related potential(40Hz AERP) . METHODS Pure tone audiometry,ABR and 40Hz AERP detection were performed in 120 recipients from whom 86 ears were available to be analyzed. According to the styles of configuration of hearing,we divided the 86 ears into 3 groups. There were 37 ears in flat style group,29 ears in descent style group,20 ears in ascent style gro...

如何客观评估听阈一直是临床听力学的一项重要课题,我们对86耳听力损失患者进行纯音听力测试、40Hz听觉相关电位(40Hz auditory event related potential,40Hz AERP)阈值、听性脑干反应(auditory brain stem response,ABR)阈值检测,将三者进行统计学分析,得到用40Hz AERP阈值、
