摘要
Abstract
The digital hearing aid system requires the use of acoustic signal decomposition filter banks to achieve loudness compensation function. Due to their controllable subband distribution, re-configurable filter banks can provide high-quality loudness compensation for different types of patients suffering hearing loss. Given this, their research and design have received widespread attention. There are various design methods for re-configurable filter banks, with each displaying its own characteristics in terms of overall structure and technical means. This article comprehensively analyzes and compares the existing design methods of re-configurable filter banks from the aspects of technical means, overall structure, and functional performance, etc., and provides prospects for future development directions.关键词
