loudness compensation wide dynamic range compression gammatone filter banks hearing aids
To alleviate the conflict between audibility and distortion in the conventional loudness compensation method, an adaptive multichannel loudness compensation method is proposed for hearing aids. The linear and wide dynamic range compression(WDRC)methods are alternately employed according to the dynamic range of the band-passed signal and the hearing range(HR)of the patient. To further reduce the distortion caused by the WDRC and improve the output signal to noise ratio(SNR)under noise conditions, an adaptive adjustment of the compression ratio is presented. Experimental results demonstrate that the output SNR of the proposed method in babble noise is improved by at least 1.73 dB compared to the WDRC compensation method, and the average speech intelligibility is improved by 6.0% and 5.7%, respectively, compared to the linear and WDRC compensation methods.
