Abstract

Sound source localization has potential applications in the research areas of noise recognition, video conference system, intelligent robot design, and so on. In order to focus the target sound source in an enclosed space with only one sensor, a time reversal mirror algorithm has been developed based on the reciprocity theorem and the time reversal invariance of linear wave equation. To test the algorithm the localization experiments have been taken in two real rooms: a half-anechoic chamber and a meeting room under various conditions of sound absorption and source-receiver distance. The results have shown that this algorithm can accurately localize the target sound sources and is robust.
