Traditional sound source localization algorithm depends on high accuracy sensor array. A new algorithm based random sensor location is proposed using wireless sensor network in this paper. This algorithm adopts the least square method to estimate sound source location, through computing the delay among some sensor nodes with random location information of themselves. In addition, we introduce threshold to reduce the iteration error and clustering method to decrease the time complexity. Simulation experiment results show that this algorithm has a larger detection range than current algorithms, and acquire accuracy position at the same time.
