“…Because hearing loss is commonly more severe for high-frequency signal than low-frequency signal, the gain of the loudness compensation should be modified with the frequency of the signal [2] [3]. Recent years some multichannel loudness compensation schemes have been proposed to implement different gains for different frequency bands, and most of these schemes are based on the equal frequency bandwidth.…”

Loudness compensation is one of the most important functions of hearing aids. Because hearing loss is commonly more severe for high-frequency signal than low-frequency signal, the gain of the loudness compensation should be modified with the frequency of the signal. In this paper, a new method for multichannel loudness compensation based on human auditory is proposed. Then design algorithm for near perfect reconstruction oversampled filter banks is presented, and the parameters of the sub-band filters are designed for senile hearing loss. Simulation and experimentation results prove the validity of this method.
