摘 要:环境噪声是环境质量评价的重要指标。通过噪声监测实验,记录了华中师范大学校园内的噪声污染数据,根据国家标准评估了校园环境噪声状况。试验采用网络剖分法,分别于昼间7:30~10:00和夜间22:00~22:55两个时间段对等效声级进行了测定。实验结果表明:昼间噪声污染更为严重,平均噪声超标率达到26%,夜间噪声污染相对较轻,但噪声超标率也达到19%。校园内不同功能区的噪声来源不同,工程施工产生的噪声是主要的污染源,影响比重达到58%。根据实验结果,校园声环境质量一般,需要对现状提出合理的改进建议。Environmental noise is an important index of environmental quality evaluation.Through the noise monitoring experiment,the noise pollution results in the campus of Central China Normal University were recorded,and the environmental noise status of the campus was evaluated according to the national standards.The equivalent sound level was determined in two time periods:7:30-10:00 day and 22:00-22:55 night.The experimental results showed that the daytime noise pollution was more serious,with an average noise overshoot rate of 26%,while the nighttime noise pollution was relatively light,with a noise overshoot rate of 19%.The noise sources of different functional areas on campus are different,and the noise generated by engineering construction is the main pollution source,affecting 58%.According to the experimental results,the quality of campus acoustic environment is average,and reasonable improvement suggestions should be put forward.
