Abstract
There is considerable evidence for the existence of a cochlear amplifier which serves to increase the sensitivity and frequency selectivity of the cochlea to low intensity sounds (Davis, 19S3). Earlier models of traveling-wave amplification in the cochlea used negative damping components to supply the additional energy used to power the cochlear amplifier (Kim, et al., 1980; de Boer, 1983; Koshigoe and Tubis, 1983). The negative damping models are now being replaced by more realistic feedback force models in which the fast motile response of the outer hair cell is implicated as the driving force for the cochlear amplifier (Geisler, 1986; Zwicker, 1986; Neely and Kim, 1987).
