Abstract: How much can weather conditions influence the effectiveness of automatic monitoring of noise? And is it necessary to carry on synchronous meteorological monitoring for the noise automatic monitoring? In order to answer these questions, a deep analysis is required. Based on the monitoring data and related information, the correlation between sound level and wind speed is analyzed. The results indicate that wind speed should be measured simultaneously in noise automatic monitoring to ensure the reasonableness and accuracy of the data. The noise monitoring data must be modified or validated according to wind speed monitoring data.

Key words: acoustics, automatic monitoring of noise, weather conditions, sound level and wind speed correlation, analysis

摘要： 气象条件对噪声自动监测数据有效性的影响究竟有多大，噪声自动监测是否要同步进行气象监测，这些都需要进行深入的分析研究。结合大量监测数据及相关资料，重点对环境噪声监测中声级-风速相关性进行分析，提出进行环境噪声自动监测时，为保证监测数据的科学性和准确性，应同步进行风速测量，结合风速监测数据对噪声监测数据进行有效取舍。
