Abstract
It is extremely important to estimate the spatial location of sound source under various vibrations and noise phenomena. With this background, techniques for estimating the location of sound source as non-contact testing are widely used for understanding various vibrations and noise problems intuitively. In this study, our goal is to estimate spatial location of sound source by the combined method of MUSIC algorithm as well as Spatial Smoothing Processing (SSP) and Scanning Technique. In particular, the handy microphone array system for evaluating the performance of combined method was developed. This paper presents both the analysis method and performance of combined method, and demonstrates the performance tests for estimating the spatial sound source location. As a result, it is possible to estimate the spatial sound source location with high accuracy applying the combined method through a series of experimental and computational examinations.
