环境噪声监测及评价研究

Research on Environmental Noise Monitoring and Evaluation

通过监测重庆交通大学校园内教学区、生活区环境噪声和校园外道路交通噪声,根据声环境质量标准和噪声污染指数法进行了校园噪声污染现状评价及对比分析。实验结果表明:重庆交通大学校园内外环境昼夜均存在一定程度的噪声污染,夜间较昼间更为突出,校园外部环境噪声大于内部,校园内部以学生生活区慧园最为显著。据此,就校园环境噪声污染提出了防治措施及建议。

This paper evaluated the comparative analysis of campus noise pollution by monitoring the environmental noise and campus traffic noise in the campus teaching and living areas, traffic noise outside the campus of Chongqing Jiaotong University, according to the acoustic environmental quality standard and the noise pollution index method. The experimental results showed that there was a certain degree of noise pollution in the Chongqing Jiaotong Univer- sity campus of internal and external environment at day and night. The night was more outstanding than the day; the campus external environmental noise was bigger than internal noise; the students＇ living area Hulyuan of internal campus was the most significant. Finally, the control measures and proposals for campus environmental noise pollu- tion were presented.
