摘要
以中南民族大学为例,采用网格测量法将校园等分为47个网格,进行声环境测量,并根据《声环境质量标准》对测量结果进行分析和评价。结果表明:中南民族大学近80%的校园区域,其昼间噪声值存在不同程度的超标现象,部分区域超标率达40%以上。教学区、食堂区、宿舍区、运动区、休闲区和办公区的等效连续A声级的平均超标率分别为9%、15%、7%、22%、13%和26%,校园内的声环境总体情况不乐观。针对此情况,对控制校园噪声提出了一些建议。该实验涵盖物理、环境科学、环境工程等多个学科,有益于学生综合能力的培养及环保意识的提高。
Take South-Central University for Nationalities as an example,the campus was divided averagely into 47 grids by the grid measurement method to measure the acoustic environment.The results were analyzed and evaluated according to the acoustic environmental quality standard.The results showed that in about 80%of campus areas of South-Central University for Nationalities,the daytime noise value exceeded the standard in different degrees,and the over-standard rate in some areas even exceeded 40%.In the teaching area,canteen area,dormitory area,sports area and office area,the average over-standard rate of the equivalent continuous A sound level was 9%,15%,7%,22%,13%and 26%,respectively.It is not optimistic for the overall acoustic environment of campus.In view of this situation,some suggestions on campus noise control were put forward.The experiment covers physics,environmental science,environmental engineering and so on.It is beneficial to the cultivation of students comprehensive ability and the improvement of their awareness of environmental protection.
