Abstract

A robust hearing aids system which will simultaneously conduct hearing compensation and noise removal that used wavelet packet transform (WPT) was proposed. The speech enhancement can improve perception in noise for hearing impaired listeners. It removes background noise without introducing noticeable perceptual distortion. Shaped noise was added to stimulate the effect of high frequency hearing loss. The system can serve as an efficient and effective way to develop and evaluate algorithm for hearing aids application.
