The cochlea is known as one of the discriminating organs in the auditory system. Recently this organ has been considered not only to receive sound passively, but also to produce acoustic energy actively in order to sharpen its own tuning function. Otoacoustic Emissions (OAE) are recognized as a byproduct of this active function. Although many reports related to OAE have been published, there are still basic unknown points of the OAE, e.g. ripple of stimulus-frequency OAE and latency of transiently evoked OAE. Therefore, in this paper, first, a one-dimensional model of the cochlea, which includes the active function of outer hair cells, is established. Then comparing numerical results with the experimental data, an attempt is made to clarify the mechanism of OAE theoretically.
