摘要： 听觉诱发电位是由声刺激诱发听觉系统所产生的电位活动。对于不能提供可靠或可信听阈的被检者，目前已有多种听觉诱发电位检测方法来对其听觉功能进行客观评估，包括皮层电反应测听、听性脑干反应、40 Hz听觉相关电位、听性稳态反应等。本文对上述4种方法的研究进展进行了综述，发现4种检测方法都能很好地反映行为听阈，其中皮层电反应受被检者的觉醒状态影响很大，不易控制；听性脑干反应是目前应用最广的检测方法，不受意识的影响，但主要反映了高频听阈；40 Hz听觉相关电位灵敏度较高，但易受睡眠等因素影响；而听性稳态反应由计算机自动判断，可以对双耳多个频率同时进行检测，在测试时间方面具有很大优势。目前在听觉功能障碍的法医学鉴定中，如何根据多种检测方法的优缺点进行选择性组合，仍将是一项艰巨的任务。

Abstract: Auditory evoked potential（AEP） is the electric activities originating from auditory systems evoked by sound stimulus. AEP include cortical electric response audiometry（CERA）, auditory brainstem evoked response（ABR）, 40 Hz auditory event related potentials （40 Hz AERP）, auditory steady-state response（ASSR）, etc. For the subjects who cannot provide reliable or accurate behavioral hearing threshold, those techniques have been explored to evaluate the behavioral hearing threshold objectively. These techniques are reviewed in this article and are found that they could reflect the behavioral hearing threshold very well. CERA is difficult to operate because it is affected by the subject’s wakefulness. ABR is the most widely used method currently and is not affected by the subject’s consciousness, but it only reflects high frequencies. 40 Hz AERP has good sensitivity, while its results highly depend on the subject’s consciousness. ASSR can be operated by using multiple frequency stimuli simultaneously to both ears and the test time is short. It is still a very difficult task to combine different techniques according to their characteristics in forensic audiology.
