通用环绕声系统及其重发声场的研究

First time in China, the project studied surround sound and its sound field systematically. Based on related sychoacoustic principle and software of sound field analysis, the defects of 5.1 channel surround sound system are analyzed and a method to improve the system is proposed. A new 6.1 channel general horizontal surround sound system and a spatial surround sound system are proposed. The systems are compatible with the presented similar systems but have much better effects. A virtual surround sound system is also obtained and the defect of current similar system has been remedied. Now, the research group is cooperating with TCL Ltd to put the virtual surround sound system into practical use. The project has filled a gap in the field of sound reproduction in China.

利用声场分析的方法，研究一种与现有系统兼容的新的通用平面环绕声系统，它将克服现有系统的缺陷。在此基础上，进一步研究通用的空间环绕声系统。在此基础上，进一步研究通用的空间环绕声系统。新系统在广播，电影，电视家庭放音，多媒体计算机等方面有广泛的应用前景。本项目的研究将填补国内在这方面的空白，对发展电子，音像等工业有较大的作用。
