助听器双重反馈抑制算法中的参数效应研究

The Parameter Effect of the Dual-Mode Feedback Cancellation Algorithm for Hearing Aids

本文通过分析对助听器使用的双重反馈抑制算法的性能,对两种不同原理而又相对独立的反馈抑制算法中的关键参数进行研究。笔者设计了多组声学模拟实验,比较不同参数设置下助听器增益补偿、反馈抑制效果及音质清晰度等方面的综合影响对算法性能进行评估,从而指导临床听力师在验配助听器时更好地解决声反馈问题。

This paper analyzes the performance of the dual-mode feedback cancellation algorithm for hearing aids,by studying the parameter effects of two algorithms with different basic principles used simultaneously in a specified hearing aid.This paper provides a fitting guideline for audiologists to solve the clinical feedback problem,by comparing and analyzing the algorithm performance such as hearing compensation,sound quality and speech intelligibility in the designed experiments.
