The pressure applied to the basilar membrane is transmitted to the outer hair cells, which act on the cilia and back on the basilar membrane. The interaction of basilar membrane and outer hair cells is a nonlinear, non-local active system. Active amplification and nonlinear saturation terms as additional forces triggered by the outer hair cells s and acting on the basilar membrane, can be seen as generated by nonlocal feed-forward longitudinal interaction. A model based on sound amplification method is proposed and studied to enhance the ability of the hearing impaired.
