Wavelet Analysis in Recruitment of Loudness Compensation

Abstract

Wavelet-based multiband dynamic range compression is developed to compensate for a common hearing impairment known as recruitment of loudness. The algorithm combines standard compression with intensity-level dependent gain calculation. Complexity and performance are similar to traditional techniques. Further, the methods established here can be applied to the more adaptive wavelet packets and local cosine bases which model the speech signal more closely. © 1993 IEEE
