%X Otoacoustic emission is a hot spot of research in Otolaryngology. Transient evoked otoacoustic emission was thought to be in lack of frequency resolution. To overcome this limitation, the authors analyzed TEOAE signal with wavelet transform. An energy distribution was obtained by extracting the average energy from the different scales of wavelet. TEOAE energy distribution takes the average energy of the normal hearing persons as 0 dB, and 5% percentage at single side as the 95% normal value range. TEOAE energy distribution represents the energy loss and is convenient for the comparison to the pure tone audiogram. This paper shows that quantitative frequency information can be extracted from TEOAE. The method used in this paper provides an effective means to analize TEOAE quantitatively and may be applied to the clinical work.
