噪声信号是通过振动所产生的。振动信号处理在近30多年来经历从模拟信号的人工分析到数字信号的计算机处理的演变过程，振动信号的处理分析无论在理论基础还是在技术上都发展得很快。特别是在计算机技术迅猛发展的今天，价格低廉的普通个人电脑也可以替代价格昂贵的专用振动信号处理设备，以达到人们对生存空间环境噪声进行定量监测与分析目的，具有相当广泛的推广实用价值。
信号的处理和分析方法有信号的预处理、时域分析方法和频域分析方法。本文中介绍了几种常用的振动信号分析方法，主要有采样数据的平滑处理、数字滤波、FFT变换等。
翻译成英文，希望好心人能帮忙.
不要金山词霸这种机械翻译的，准确率要高。

What calculator handle that artificial that voice the signal pass to vibrate a produce of. The vibration signal handle to experience in near more than 30 ses to analyze the arithmetic figure signal from the emulation signal to turn into the handling of process, vibration signal the analysis to regardless all develop very and quickly on the theories foundation still in the technique.Especially in the calculator technique the cheap and common personal computer of today, price of the fast and fierce development can also act for the price the signal of expensive appropriation vibration to handle the equipments, then attain people to expansion exist space environment voice proceed fixed amount monitor with analysis purpose, had very extensively the practical value.
Handling of signal with analysis method contain for preparing of signal to handle, the analysis method analyze the method with . This text inside introduced the analysis method of a few and in common use vibration signa
