Abstract

According to indirect experimental evidence, derived mainly from acoustic cochlear emissions (Kemp,1978), wave propagation in the cochlea is supported by metabolic energy. The motility of ORCs associated with an alternating electrical field (Brownell et al. 1985) is likely to be the mechanism for the energy delivery (e.g. Ashmore,1986). If the cells respond mechanically to the alternating electrical fields they themselves generate, conditions for an electromechanical feedback are provided. Several models of the feedback were proposed in the past (e.g. Kim et al., 1980; Mountainet ale 1983; Neely and Kim, 1986) but were not sufficiently explicit to establish the required structural and phase conditions. Analysis of these conditions and an experimental confirmation of its crucial results are the subject of this article.
