DMS动声录音与效果制作技术的研究

The Study of Recording and Reproduction of DMS

多通道动声系统(DMS)是基于声场优化原则与惠更斯原理的新型多通道拾音还音系统。该系统录音部分采用近场与远场结合的相控麦克风阵列拾音方法,重放部分根据声道特点有效的分配直达声和混响声。本文基于心理声学原理采用对比实验,通过语义细分法,研究DMS系统与立体声系统的听感区别。通过本研究,证明了DMS产生的相干声场可以有效地改善听音效果,为声场的综合技术与多声道系统的未来发展方向从听觉心理学的角度提供了理论基础。

Dynamic Matrix Sound （DMS） is a multiple channel recording- and- playback sound system based on source synthesis and Huygens principle. The recording part of the system uses the phase - controlled microphone array with both near - field and far - fields pickup. The playback system uses the unique characteristic of the dynamic matrix to process each channel. Based on psychoacoustics theory,this paper uses the Semantic differential （SD） method to compare the different hearing effect on people when using DMS and stereo sound systems. The controlled experiment shows that sound field synthesized by DMS system can significantly improve the sound quality and listener experience. Thus,from the psychoacoustics point of view,the multi - channel DMS system produce more comforting sound field.
