Abstract
In solving the noise problem in the factories and complex machineries, the first necessary step for the effective improvement is to exactly know the properties of the noise; loudness, frequencies and location of them. The purpose of this work is to develop a ready-to-use noise source visualization system. This system consists of a foldable handy microphone array and a portable computer with source analyzing software. In order to realize a real-time analysis, we have improved the hardware and optimized the software code for noise source localization. By superposing the captured image on analyzed noise source map, we can "visually" understand where the noise comes from. This paper describes the outline of this system and some application results.
