摘要
介绍了借助于计算机普通的声卡对环境噪声进行监测和分析的系统。该系统利用VC语言编写程序界面实现信号的监测、采集和分析,直观定量地用图形实时显示环境的噪声分布情况,并且可以精确计算出噪声重要参数。
The paper introduces a system of noise signal supervision and analysis based on a common sound card in a computer. This system, programmed by VC language, can not only collect and analyze noise varying from time to time, but also display and reproduce noise signal. So we can observe noise distribution visually and calculate accurately most important parameters of noise.
