Abstract
This paper presents a computer simulation of a long distance time domain sound source localization algorithm that localizes a single sound source by using two separated channel microphones. This paper uses the Time-Difference-Of-Arrival (TDOA) method for estimating the time delay difference between the incoming sound signals to microphones using the Average-Magnitude-Difference-Function (AMDF) algorithm. This algorithm has the main advantage of requiring no multiplication operations. The key design objectives are to reduce hardware circuit complexity and implement the algorithm on FPGA board. The computer simulation results have average error within 8° of accuracy in 1 to 5 meters. © 2008 Springer-Verlag Berlin Heidelberg.
