降雨对噪声自动监测数据的影响分析
徐辉,马俊文
北京市环境保护监测中心
摘要:
选取北京市近5年夏半年(4-9月)的降雨数据及相关噪声自动监测小时等效声级,利用数学统计软件进行有雨-无雨声级差异性分析、声级-降雨相关性分析及平均声级-雨量变化趋势分析等,提出降雨确实对噪声自动监测小时数据有一定贡献,不同雨量对不同功能区噪声影响不同,建议噪声自动监测系统建设时应考虑雨噪声影响,以保证对声环境质量评价的科学性和准确性。

Analysis on the Effect of rainfall on automatic noise monitoring data
Abstract:
Retrieving rainfall hour data and related hourly equivalent noise level by automatic monitoring from April to September of the latest 5 years in Beijing, and carry out several statistical analysis including the noise levels differentiation between rainfall and rainless periods, correlation analysis between noise level and rainfall, changes trend analysis between average noise level and precipitation. The results show that rainfall do have some impact on the automatic monitoring, and different precipitation has different impacts on noise levels of various functional zone sites. It’s suggested that rainfall influence on noise level should be considered during the process of the establishment of noise automatic monitoring networks to ensure scientific and accurate assessment of ambient noise quality.
