多通路环绕声系统最佳兼容重发的研究

本文利用立体声得发的声像定位理论，提出一种新的在５．１通路环绕声系统（及其它伴随图象的环绕声系统）兼容重发普通双通路立体声信号的方法，并进行了实验验证。理论和实验结果表明：新的方法具有较宽的听音区域，稳定的前方声像，且对中心心位置的倾听者没有声像位置畸变现象，其总的效果过去提提出的方法为优。

Study on Optimum Compatible Reproduction of Multichannel Surround Sound System

A new method of compatible with ordinary two channel stereo signals 5 1 channel surround sound system(and other multichannel reproduction surround sound system accompanying with picture) by using sound image localization theory in stereo reproduction is proposed.A sound image localization experiment is also carried out.Theory and experimental results show that the new method can present a stable front sound image and a wide listening area without sound image position distortion existing.Therefore,the whole effect of this method is better than the old one. This method is also suitable to enlarge listening area in two channel stereophonic reproduction.
