摘　　要：对虚拟声系统的重发声场进行分析与实验 ,证明了采用三扬声器虚拟声重发系统可在一定程度上克服两扬声器系统的缺陷 ,其听音区域得到扩大 ,声像稳定性得到提高 .并且指出 ,三扬声器虚拟声重发的方法可用于 5.1通路环绕声的侧向声像重发、家庭影院的环绕声重发和室内声场可听化模拟 .This paper analyzes the sound field of virtual sound reproduction, and proves that, to some extent, virtual system with three loudspeakers can overcome the defect of the system with two loudspea_ kers, its listening area is enlarged and the stability of sound image is improved, and that the method of virtual reproduction with three loudspeakers can be used to recreate side image in 5.1 ch surround sound and applied to domestic use as well as the simulation of room sound field.
