Abstract: This paper presents two different sound source localization algorithms, in which the observation data are the time differences of arrival between acoustic sensors, and then combined them with the spatial position and speed of the acoustic detector array the specific location of the sound source can be determined. Simulation and experimental data are processed by the two localization algorithms in this paper, experimental results are well analyzed to verify the accuracies of the two different algorithms and to show their advantages and disadvantages. The results show that fast and accurately solution is available with rational use of the two algorithms.
