Abstract

This paper is intended to give an overview of problems of hearing impairment and audio signal processing in hearing aids. First, the physiological requirements due to hearing impairment are explained and different hearing aid types are demonstrated. The main part of the paper is dedicated to present the different audio processing methods in modern hearing aids. Especially beamforming and noise reduction systems are focussed on. Future trends mainly address binaural directional processing. Here, an approach based on blind source separation is described.
助听器:一个有趣的音频信号处理应用的最新技术,挑战和未来趋势的概述
本文综述了助听器中听力障碍和音频信号处理的相关问题。首先,解释了听力障碍的生理要求,并展示了不同类型的助听器。本文的主要部分是介绍现代助听器中不同的音频处理方法。特别是波束形成和降噪系统的重点。未来的趋势主要是解决双耳定向处理。本文介绍了一种基于盲源分离的方法。
