For accomplishing acoustic location in wireless sensor networks (WSNs), a range free acoustic localization algorithm based on perpendicular bisector partition is proposed, taking into account of reducing computation complexity and reduce the interference of the background noise. Adopting a range free perpendicular bisector partition, the proposed method can find the sub-region of the source, and the time complexity is much lower than that of existing methods. According to extensive analysis on noise, the concept of noise sensitive region is derived. Experimental results show that the proposed method has a high localization precision and low complexity.
