多通道动声系统（DMS）是基于声场优化原则与惠更斯原理开发的多通道拾音还音系统。该系统利用相控麦克风阵列进行拾音，通过一个M个输入与N个输出的多解系统，将有限的声源与无限的声场相结合，带给人们全新的听音体验。本文通过听音位置对比、主观听感区别和扬声器数目对比等三个主观评价实验，对DMS和大众熟知的传统立体声进行对比研究，得到两者主观感受方面的区别，从而得出大众对DMS的认可程度以及DMS的最佳应用范围。%Multi- channel matrix sound system （DMS） is a multi -channel input and output sound system which is based on optimizing sound field principle and Huygens~principle. The sound is picked up by phased array microphone. DMS combine the limited sound source and unlimited sound field by a multi solution system of an M inputs and N outputs,which gives people a new listening experience. In this paper,we do three subjective evaluation experiments of DMS and the conventional stereo,including the con- trast of the listening position, the difference of the subjective sense and the contrast of the speaker＇ s number,to get the difference between the two system. Then we find the mass recognition of DMS and the best application of DMS.
