| Abstract: | 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. |

| Keywords: | room acoustics microphone array sound source localization directional impulse response |
