通信声学的发展及研究现状

人类作为信息交流的主要信息产生源和信息接收槽,语言声学、心理声学和生理声学在信息技术中发挥着越来越重要的作用。作为声学与信息技术相互渗透的产物-通信声学,近十几年来随着数字信号处理技术的发展,其研究和应用领域得到了很大的扩展。本文在简述通信声学产生和发展的必然性和必要性之后,主要介绍了通信声学目前的研究领域及其应用。

The development and research areas of communication acoustics

Because speaking and hearing are the most common ways for information ex- change as information source and information sink,speech acoustics,psychoacoustics and physiological acoustics are playing a more and more important role in information technolo- gy.Communication acoustics,the result of interpenetration between information technology and acoustics,is now getting a big extension in its researches and applications,due to the development of DSP technology.This paper will mainly introduce the present research are- as and the applications of communication acoustics,after briefly introducing its history of development.
