Research of Acoustic Source Localization Technology Based On Spatial Time Delay Estimation and Intelligent Signal Analysis

Abstract

The accurate and real-time localization of sound sources is the basis of machine intelligent technology and industrial and civilian positioning applications. It can provide basic help for many applications. In this paper, first, we investigate the applicability of the generalized cross correlation (GCC) delay estimation algorithm. Secondly, we analyze and study the method of acoustic source localization for the microphone array and design a unique spatial structure. Finally, the embedded system and the human-computer interaction interface are designed to collect and analyze the data so as to obtain the accurate and real-time location of the sound source.
