Abstract

The sound source localization method that based on triangular array of wireless sensor networks (WSN) is proposed to locate the sound source and research the error distribution. Using the Time Difference of Arrival (TDOA) algorithm, the proposed sound source localization method can be used to locate the source of impulse of sound inside or around the WSN array. The simulation experiment had positioning error distribution. Simulation results show that, the effective localization region of the proposed method is mainly located inside the WSN array and extents outward across the edges of the array. The effective localization region became bigger with the WSN array scale became lager .The simulation results also show that influence of the error of WSN node position to the localization error is greater than the errors of sound arrival delay calculation. The influence of sound arrival time difference analysis error and node location error for the effect of sound source localization increased with the increase of the WSN array scale.
