Abstract
It is extremely necessary to estimate the spatial locations of sound sources under various vibrations and noise phenomena. With this background, techniques for estimating the locations of sound sources as non-contact testing are widely used for understanding various vibrations and noise problems intuitively. In this study, our goal is to estimate locations of high correlation sound sources with high accuracy by combined SSP and MUSIC methods, based on the leading edge technology of radar signal processing. Considering this objective, the handy microphone array system for evaluating the performance of the combined SSP and MUSIC methods was developed experimentally. This paper presents details of the performance of the combined SSP and MUSIC methods as well as the analysis method of the measured and experimental results of the performance tests for estimating the locations of high correlation sound sources. As a result, it is possible to find the sound source locations with high sensitivity applying the combined SSP and MUSIC methods through a series of experimental and computational examinations.
