Abstract

This paper proposes a non-equal width multi-channel loudness compensation algorithm for digital hearing aids. This method achieves a non-equal width multi-channel loudness compensation scheme based on the sensitivity of the human ear to the frequency and the perception of sound intensity. First, the voice signal is moved to the target frequency band in different proportions, and then is divided into non-equal widths, and loudness compensation and gain control are performed in each frequency band. The experimental results show that this method can effectively improve hearing and speech recognition of hearing patients, and has a high practical value.
