Abstract

Acoustic Source localization is the technique which is used to locate the sound source in a given environment. The sound source can be located with the help of sound signal recorded by the microphone. There is one original signal that comes straight to the microphone and other signals are reflections of the original signal reflected from the walls of the room. In this paper, we proposed a method of locating the sound source using the microphone array. We locate the sound source by calculating the time difference using time difference of arrival method. We process this time difference by using subband and broadband approach. The results of this paper show that we can find the position of sound source by calculating the angle towards the sound source with an accuracy of about 60-70%.
