环境噪声峰值的空间分布

Spatial distribution of environmental noise peaks

本文将正态随机过程的峰值分布理论推广到环境噪声峰值的空间分布的计算上。文中分析了杭州市环境噪声的测试数据,发现它们符合正态分布。在这种情况下,容易计算出超过某一峰值的噪声所占的空间比例,并且有可能以较少的测量数据来反映环境噪声的分布规律,从而大大减少噪声测试分析的工作量。

The theory of distribution of peaks in normal random process has been expanded to calculate the spatial distribution of environmental noise peaks. This paper analysed the noise measurement data in Hangzhou and discovered that they obey a normal distribution. In this case, it is easier to calculate the percentage of areas where the noise level exceeds a given value. There is the possibility of representing the distribution characteristic of regional noise levels with less measurement data. Therefore, the labour for noise measurement and analysis can be drastically saved in some cases.
