Abstract :
The aim of this paper is to evaluate the application of the discrete wavelet transform (DWT) to transient evoked otoacoustic emissions in order to achieve a differential diagnosis of frequency-specific hearing loss. We introduce a method to determine discriminative sets of DWT coefficients between groups of persons with normal hearing, high frequency hearing loss, and pantonal hearing loss. The validity and use of our approach is verified on a different patient group.
