【Abstract】 the sound source location method is researched in this paper.three microphones are employed to pick up the sound signal.The time difference of arrival between any two microphones is determined using an improved cross-power spectrum phase-based method.The location eqution is converted into a nonlinear functional optimazation problem,and then a novel chaotic conjugate-gradient method is proposed to solve the optimazation problem and to determine the location of the sound sourse.The experimental results show the effectiveness of the problem.更多还原
