The mechanisms by which the organ of Corti is stimulated by acoustic stimuli are discussed on the basis of experimental observations. This discussion refers to the resonance theory as well as to the traveling wave (TW) theory. The measurement of the basilar membrane displacements, of the cochlear microphonic (CM) responses to pure tones and impulses, and the recording of the intracochlear acoustic pressure seem to indicate that, at least in the basal part of the cochlea and for frequencies up to the characteristic frequency of a given location, the cochlear responses do not exhibit large phase lags and long delays which characterize the one-dimensional long-wave models (in which a TW transports the energy along the cochlear partition). These experimental observations suggest that the cochlear partition is excited simultaneously as a whole, more or less like a bank of resonators, as proposed a long time ago by Helmholtz.
基于实验观察结果，讨论了柯蒂氏器受声刺激的机制。该讨论涉及共振理论以及行波（TW）理论。对基底膜位移、耳蜗对纯音和脉冲的微音器电位（CM）反应的测量，以及耳蜗内声压的记录似乎表明，至少在耳蜗的基部以及频率高达给定位置的特征频率时，耳蜗反应不会表现出表征一维长波模型（其中行波沿耳蜗隔板传输能量）的大相位滞后和长延迟。这些实验观察结果表明，耳蜗隔板整体上或多或少像一组共鸣器一样同时被激发，这是亥姆霍兹早在很久以前就提出的。
