摘　　要：设计了一种针对城市环境噪声的广域噪声传感器网络系统,采用微型前置放大器和数字化网络采集仪组成检测系统,完成噪声信号的接收和采集,并通过软件设计完成采集的噪声信号存储、分析、显示及处理,实现了对噪声分布的图像化展示。A noise monitoring system, the wide range spread microphone network, has been developed to measure urban noise distribution. This system was made up of miniature pre-amplifier, digitizer, data transfer linking by internet; data of all sensors＇ signal were acquired by this detection system. A software system has been made to calculate the sound field, to display its sound image and to save the raw data.
