Wavelet analysis of real ear and synthesized click evoked otoacoustic emissions

Hear Res. 1994 Mar;73(2):141-7. doi: 10.1016/0378-5955(94)90228-3.

Abstract

Wavelet analysis was performed to obtain time-frequency analyses of click evoked otoacoustic emissions from normal ears and one ear with a high-frequency hearing loss; mainly to introduce this relatively new method and to show its potentials for emission analysis. The same analysis was then used to obtain time-frequency decompositions of synthesized emissions. It was found that the introduction of a slightly irregular frequency to place relation for the inner ear yielded synthetic results that were remarkably similar to those obtained from real ears.
