基于模糊矩阵法东莞理工学院校园声环境评价研究

Evaluation of Campus Sound Environment based on Fuzzy Matrix Method in Dongguan University of Technology

随着城市建设的加快,噪声污染越来越严重,已经影响在校师生的正常学习与生活。以东莞理工学院为例,运用模糊矩阵法对该校园声环境质量进行综合评价。结果表明:该校园环境噪声普通存在超标现象,昼间超标率为14.36%,夜间超标率为22.67%。校园声环境隶属度可达0.34,属于中度污染。校内外交通和学生活动是校园主要噪声污染源,可采用增加校园绿化、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。

With the acceleration of urban construction,noise pollution is getting worse,it has affected the normal learning and life of teachers and students. Taking Dongguan University of Technology as an example,this paper uses the fuzzy matrix method to evaluate the quality of campus sound environment. The results showed that the environmental noise in the campus of Dongguan University of Technology has exceed the standard phenomenon,the average daytime exceed the standard rate of14. 36%,the average night exceed the standard rate of 22. 67%. The campus sound environment of membership was 0. 34,which belonged to moderate pollution. The road around campus and student activities were the main sources of noise pollution,which can be used to improve the quality of campus sound environment by increasing the campus greening,strengthening the traffic management and noise management.
