本文将现实中采集到的一段语音加上了高斯白噪声，利用了LMS算法，将噪声滤除，仿真效果良好-This article will be collected in reality a section of voice coupled with a Gaussian white noise, using the LMS algorithm, the noise filtering, simulation results

用matlab实现巴特沃斯低通滤波器的M文件。本例读取电脑自带的XP开机声音，加上高频噪声，然后滤波看效果。-Butterworth low-pass filter using matlab M-file. This case, read the computer comes with XP start-up sound, coupled with high-frequency noise, and then filter to see the effect.

COUPLE是声场中计算耦合简正波的工具，可以根据输入的海洋环境信息和阵元信息求出声场中的本征函数和耦合简正波系数，进而合成声场，适合于水深缓慢变化（斜坡）的情况，内含说明文件一份（输入、输出文件的解释）-COUPLE is a tool for sound field calculation coupled normal mode, you can ask to speak field eigenfunctions and coupled normal mode coefficients ba
