  • A new multichannel loudness compensation method is proposed in this paper. According to the method, analysis and reconstruction sub-band filters for near perfect reconstruction oversampled filter bank are designed, then nonuniform multichannel loudness compensation based on human auditory, the sensitive feature of frequency and sound pressure level is implemented. Simulations and experiments for the typical senile patient demonstrate that the loss energy of the high frequency sound is well compensated, the intelligibility of patient is improved, and the speech detection threshold is decreased notably.
