摘　　要：噪声自动监测在中国才刚刚起步,其各项规范还没有随之确立,这就需要进行一系列的噪声自动监测实验,以获得各项规范确立的指标。通过在四个类别的标准适用区进行的噪声监测试验,利用获得的试验数据进行统计分析,找出噪声Leq小时值的统计特征,对四个类别的标准适用区各日标准方差进行计算,获得标准方差最大与最小对应的日期,分别对其进行小时噪声等效声级进行抽样,以确定功能区噪声自动监测有效时间。经计算对任一类别的适用区日均值的获得至少需要连续监测,也就是功能区噪声自动监测有效时间是18个小时以上。To obtain data for the establishment of automatic noise monitoring standard, noise monitoring experiments were conducted in zones where standards of four grades were applicable respectively. The experimental data obtained were analyzed statistically and the statistical characteristics of hourly level of equivalent noise were found out. The result of calculation indicated that a continuous monitoring was required for obtaining daily average value and the effective duration of automatic noise monitoring was more than 18 hours .
