Otoacoustic emissions are numerically simulated from a nonlinear nonlocal cochlear model solved in time domain by means of the space-state matrix technique. The feedback mechanism localized in the outer hair cells system is modeled as a nonlinear active force proportional to the total pressure acting on the basilar membrane or as an antidamping nonlinear term proportional to the velocity of the membrane itself. The model seems to be a very good tool for simulating cochlear dynamics in different regimes of the cochlear parameters and in particular when strong nonlinearities are put into the model.

Abstract
Otoacoustic emissions are numerically simulated from a nonlinear nonlocal cochlear model solved in time domain by means of the space-state matrix technique. The feedback mechanism localized in the outer hair cells system is modeled as a nonlinear active force proportional to the total pressure acting on the basilar membrane or as an antidamping nonlinear term proportional to the velocity of the membrane itself. The model seems to be a very good tool for simulating cochlear dynamics in different regimes of the cochlear parameters and in particular when strong nonlinearities are put into the model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
