Abstract

In this work, we introduced a sound source localization system based on fiber optic FP cavity microphones using time difference of arrival, and conducted experimental analysis on the positioning accuracy of localization system within a range of 1m×1m. We applied cross correlation to estimate the time difference of arrival, and combined Chan localization algorithm and Taylor localization algorithm to estimate the coordinate position of the sound source. Experimental results indicated that the maximum deviation between the estimated coordinates and the actual sound source coordinates in the x-axis and y-axis directions was less than 2.35 cm.
