A Sound Source Location Method Based on Wireless Sensor Network

摘要：

　　The sound source location method includes time delay estimation and location.This paper proposes a time delay estimation algorithm based on the arc tangent transformation and the algorithm still has a good stability when the background noise of the public places is non-Gaussian noise.Secondly,the range and angle location algorithm was used to determine the location of sound source and the error analysis was carried out.The research results show that the cross shaped array with five elemnets has good loaction performance because it can eliminate the effect of location error caused by azimuth angle.
