Abstract

A cochlear model including a nonlinear function for somatic motility of the outer hair cell (OHC) has been proposed for compression relating to cochlear nonlinearity evolved by a tone. However, the mechanisms of two-tone suppression, also known as cochlear nonlinearity, are not yet clear. The present study investigates the mechanisms of two-tone suppression in a simulation using the previously proposed cochlear model. Twotone suppression by an OHC model is thus presented. The simulation results are consistent with the results of physiological experiments and show the possibility that two-tone suppressiona is generated by the somatic motility of the OHC. Copyright
