摘　　要：提出了一种由重复发射的声源配合缓慢转动的传声器组成的、等效于圆形传声器阵列的室内声学测量系统。阐述了这种测量系统的特点及其理论基础,介绍了它在室内声场中若干涉及声源定位及声场空间特性测量等方面的应用,并结合实例作了讨论。系统具有较强的适应性及实用性,在室内声学测量中具有广泛的应用前景。A room acoustical system composed of a repeatable inspirited sound source and a slowly rotating microphone （RRS） is proposed which is equivalent to rounded microphone array. The principle and characteristic of this system is explained in this paper. Furthermore, the application of the system to localization of sound source and analysis of the spatial information of sound field is described. This system will be widely applied to room acoustical measurement due to its adaptability and practicality.
