东莞理工学院莞城校区校园噪声测量与评价

Measuring and Evaluating the Environmental Noise in the Guancheng Campus of Dongguan University of Technology

对东莞理工学院莞城校区校园环境噪声进行实地监测,分析了该校园的环境噪声污染现状,绘制了校园环境噪声分布等值线图,并采用污染指数法进行了噪声评价。结果表明:该校园环境噪声存在超标现象,全年噪声监测均值昼间达58.81 dB,夜间达55.61 dB,声环境质量处于吵闹水平。校园内外的交通噪声与学生校园活动是主要噪声污染源,建议通过控制噪声源、增加校园绿化、加强校内交通管理与噪声管理等措施,改善校园声环境质量。

The paper did some monitoring of environment noise in the Guaneheng campus of City College of Dongguan Uni- versity of Technology, analyzed the situation of the campus environmental noise pollution, drew the distribution contour map of the campus environment noise, and used the noise pollution index method for evaluation. The results showed that： The campus noise exceeded the standard, the noise value was up to 58.8ldB in daytime and 55.61dB at night in a year, and the sound quality of the environment was in the noise level. The traffic noise inside and outside schools and students activities in campus was the main noise sources of pollution. It was recommended that control the noise source, increasing the campus green, strengthen the campus traffic management and noise management measures, to improve the quality of campus acoustic environment.
