Measurement of two-tone effects in the cochlear microphonic and summating potential indicates that the growth of suppression is different for these two cochlear potentials. Whereas the CM response to the fundamental is reduced 10 dB for each 10 dB increase in suppressor level, the SP decreases at a faster rate; approximately 20 dB per 10 dB increase. Slopes of functions for the CM response to the second harmonic are similar to those for the dc component. Since these results are consistent with the notion that suppression operates by attenuating the input to the CM generator, they are consonant with a mechanical origin of suppression.
对耳蜗微音器电位和总和电位中的双音效应进行测量表明，这两种耳蜗电位的抑制增长情况有所不同。耳蜗微音器电位对基频的响应会随着抑制声级每增加10 dB而降低10 dB，而总和电位下降得更快，每增加10 dB约下降20 dB。耳蜗微音器电位对二次谐波响应的函数斜率与对直流分量的斜率相似。由于这些结果与抑制作用是通过衰减耳蜗微音器电位发生器的输入这一观点一致，因此它们与抑制的机械起源相符合。
