Time-domain model of the inner ear to study nonlinear responses
2015
Introduction: The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them. Computational Methods: A simple box model of the cochlea is used. The applied physics interface is acoustic shell interaction (acsh). The basilar membrane (BM) and round window (RW) are modeled as shells. The oval window (OW) supplies an
