The responses of the auditory nerve and brain stem auditory nuclei have been recorded with ear lobe and scalp electrodes in response to unfiltered click stimuli which excite mainly high-frequency nerve fibers. In order to overcome this limitation, normal subjects and patients with hearing loss were stimulated with third-octave filtered clicks with center frequencies of 250, 500 and 1 000 Hz. Analysis of the responses suggests that these lower-frequency stimuli excite lower-frequency cochlear nerve fibers. It is concluded that low-frequency filtered clicks can be used to complement unfiltered clicks in order to obtain a more complete objective audiogram.
已使用耳垂电极和头皮电极记录了听神经和脑干听觉核的反应，以回应未经过滤的滴答声刺激，这种刺激主要激发高频神经纤维。为了克服这一局限性，对正常受试者和听力损失患者使用了中心频率为250、500和1000Hz的倍频程滤波滴答声进行刺激。对反应的分析表明，这些低频刺激激发了低频耳蜗神经纤维。得出的结论是，低频滤波滴答声可用于补充未经过滤的滴答声，以便获得更完整的客观听力图。
