Control of otoacoustic emission scattering waveform with anti-noise

Abstract

We demonstrate a framework for eliminating significant perturbations along a cascade scattering model of the inner ear. This allows for the conception of a novel scheme of acute anti-noise stimulation at the cochlear level that can be particularly applicable to the class of tinnitus (ringing in the ear) that is aurally originated (peripheral). Peripherally induced tinnitus is often associated with the occurrence of spontaneous and evoked otoacoustic emissions, partially described by Kemp echoes, the basis of the scattering cochlea model (Sellami and Newcomb, IEEE Trans. Circuits and Systems-I, vol. 44, no. 2, pp 174-180, 1997). We propose that a refined version of the work presented here can be fit to individuals with hearing-loss induced tinnitus.
