从磁盘中的txt文件中读取数据，并对数据进行均方根计算，并进行粗大误差剔除-Txt file from the disk to read data, and calculated the root mean square data, and the gross error removed

基于蒙洛特实验，通过不同的信噪比，得到信号比和均方根误差的实验结果。-Based on the Mengluote experiment, through different signal to noise ratio, experimental results are obtained to signal ratio and the root mean square error.

粒子滤波 PF( Particle Filtering) 是在 贝叶斯滤波框架下基于 Monte Carlo 采样的统计滤波方法，可解 决非线性、非高斯的滤波问题，声源跟踪就属于这类问题。近年 来，基于粒子滤波的声源跟踪算法已成为研究的热点。 -he real acoustic data recorded in a typi- cal meeting room using a small-scale microphone array is used for tracking
