An Improved Loudness Compensation Method based on Multi-frequency Wide Dynamic Range Compressione

摘要

This paper presents a loudness compensation algorithm model based on multi-channel wide dynamic range compression technology, which can flexibly change the gain according to the hearing dynamic range of hearing loss patients in different frequency ranges. At the same time, a smoothing algorithm is added to reduce the gain difference between adjacent frequencies and improve speech intelligibility. A series of experiments were conducted using the English corpus to evaluate the performance of the loudness compensation model.
