交通干线对大学校园噪声污染的研究及评价——以西华师范大学华凤校区为例

Evaluation of Traffic Noise Pollution on the Campus of China West Normal University

通过对西华师范大学交通干线噪声的连续监测,采用等效连续A声级计算噪声值,并利用声环境质量标准和环境噪声质量等级标准评价与分析校园的交通噪声污染状况。研究结果表明:整体而言,西华师范大学校园交通干线的昼间噪声监测均值达到65.8d B,超标率为19.64%,声质量处于中度或重度污染水平;从监测点上看,栋梁门的噪声均值最大,为67.1d B,超标率为22.00%;从监测时间上看,8:00-9:30am的噪声值最大,约66.1d B;在一周中,周一至周四的噪声值超过均值65.75 d B,而周六的噪声值最小,约64.7 d B。通过对大学校园区交通干线噪声的监测与分析,以期为制定有效的噪声治理措施、改善该校园的声环境质量提供必要的基础数据支持。

Through continuous monitoring of the noise of traffic arteries around the campus of China West Normal University,the method of equivalent continuous sound level A was used to evaluate the value of noise,and traffic noise pollutions of the campus were evaluated and analyzed of the campus by standards of acoustic environmental quality and the environmental noise quality grade. The results shows that: 1 Overall,monitoring daytime noise mean of China West Normal University campus traffic trunk up to 65. 8 d B,exceeding the standard rate of 19. 64%,and sound quality is at a moderate or severe pollution level; 2 From the view of the monitoring points the noise value of the gate is the maximum,and the noise value is 67. 1 d B,exceeding the standard rate of 22%; 3 From the monitoring time,8: 00- 9: 30 am value of noise is the maximum,and the noise value is 66. 1d B. On Monday to Thursday noise value has exceeded the mean,and the noise value is relatively small on the weekend. Through monitoring and analysis to the China West Normal University traffic noise,this paper can provide necessary support to make effective sound quality of the environment noise control measures and improve the sound quality of environment of the campus.
