传声器阵列的声源定位研究

Study on Acoustic Source Localization Based on Microphone Arrays

对传声器阵列进行了总体概述,研究了基于传声器阵列的声源定位所面临的问题,分析和比较了几类主要的声源定位方法。给出了一种基于时间到达差的声源定位在处于混响环境下时延估计的有效算法并通过实验验证了该算法。

This paper describes the microphone arrays generally and analyses the problem in the acoustic source localization. Three main methods of that are compared. A robust method based on linear regression for speech signal time delay estimation is presented and it is proved better performance than GCC method through experiment in the reverberant rooms.
