WAVELET ANALYSIS OF REAL EAR AND SYNTHESIZED CLICK-EVOKED OTOACOUSTIC EMISSIONS

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
