Abstract: Acoustic source location is one of the research point in the acoustic technique．In this paper,we firstly use the idea of TDOA (Time Difference of Arrival) in the acoustic location system design；Putting three or more microphones in the open area,collecting acoustic signal and calculate the time delay between the different microphones,then use a new cooperative location algorithm based on Chan and Taylor algorithm to estimate the target location．The simulations and tests indicate this system can effectively locate the acoustic target in open area,and has stable performance.
