基底膜反应单音进行了测量，使用激光测速仪，在一个网站的灰鼠耳蜗位于3.5毫米，从其基底端。对低水平（80 dB）的反应最大的反应是由频率低于CF约0.4-0.5倍频程的音调引起的。对于远高于CF的刺激频率，响应停止随频率增加而降低：达到平台。频率在CF附近的响应的压缩增长伴随着强度相关的相移。死亡消除了所有的非线性，降低了灵敏度在CF多达60-81分贝，并导致一个相对相位领先CF。(C)1997年美国声学学会。
Basilar-membrane responses to single tones were measured, using laser velocimetry, at a site of the chinchilla cochlea located 3.5 mm from its basal end. Responses to low-level (80 dB the largest responses are elicited by tones with frequency about 0.4-0.5 octave below CF. For stimulus frequencies well above CF, responses stop decreasing with increasing frequency: A plateau is reached. The compressive growth of responses with frequency near CF is accompanied by intensity-dependent phase shifts. Death abolishes all nonlinearities, reduces sensitivity at CF by as much as 60-81 dB, and causes a relative phase lead at CF. (C) 1997 Acoustical Society of America.
