Abstract

Otoacoustic Emissions are of clinical interest due to their relationship with the function of the peripheral auditory system. In this paper, a procedure is proposed for localizing the hearing loss region on the basis of clinically detected transient-evoked otoacoustic emissions (TEOAE). The continuous wavelet transform is utilized to decompose the TEOAE, and the root mean square of each wavelet scale is treated as the quantitative criterion for the localization. The results obtained by this method agree reasonably well with those by audiogram and DPGRAM. The work described provides a clinically useful method for the analysis of TEOAEs
