Abstract

This paper presents the design of an acoustic sensor array for sound source localization and object detection. An FPGA based data acquisition system is developed for a flexible acoustic sensor array platform. An anechoic chamber is designed to create a clean environment which isolates the experiment from external noises and reverberation echoes. We investigate direction of arrival estimation and source localization experiments with different geometries and with different numbers of sensors. We further present a discussion of parameters that influence the sensitivity and accuracy of the results of these experiments.
