| 摘 要： | 目前,我国确定城市环境噪声常采用地面网格点测值,再求其能量平均。该方法工作量极大。本文就城市环境噪声的高空监测值与地面网格测值间的定量关系作了理论推导。其结果与所进行的实验数据相符合。论文表明,用有限几个高空监测值来替代众多的地面网格点测值是可能的。

| Abstract: | Ground measurements of latticed points are usually made and the mean energy of the measuring values is then found to determine the urban environmental noise in our country for the time being. A large number of work load is indispensable by this method. In this paper, the relationship between the altitude monitored values and the ground latticed measuring values of the urban environmental noise are derived theoretically. The theoretical results are in agreement with the experimental data. It is shown that to use limited number of monitored values of the altitude points instead of those of numerous ground latticed measuring points is possible. |
