交通噪声对暨南大学环境的影响

目的：考察中山大道交通噪声对暨南大学北区以及华南快速干线交通噪声对暨南大学东区的影响。方法：采用24h和1周连续监测方法，分别统计监测点的等效声级Leq、昼间等效声级Ld、夜间等效声级Ln。结果：北区监测点的Ld为61．6dB，Ln为58．7dB；东区3个监测点的Ld分别为63．9、61．8、60．2dB，Ln分别为58．7、51．6、47．5dB，均超过了国家标准中的1类标准，1周连续监测结果显示，北区和东区居民所受到的噪声污染是长期而不间断的。结论：暨南大学东区和北区噪声普遍超标。随着城市机动车辆数的继续增加，形势将越来越严峻。

Analysis of effect of traffic noise on the environmental quality of Jinan University

Aim: To monitor and analyze the effects of traffic noises along Zhongshan Road and Huanan Expressway on the environmental quality of North Zone and East Zone of Jinan University. Methods: The equi- valent sound level (L eq ), day equivalent sound level (L d) and night equivalent sound level (L n) at every monitoring site were measured by 24-hour and one-week consecutive monitoring methods. Results: The 24-hour consecutive monitoring results showed that at the monitoring site of North Zone, L d was 61 6 dB, L n was 58.7 dB; at the three monitoring sites of East Zone, L d were 63 9, 61 8, 60 2 dB, L n were 58 7, 51 6, 47 5 dB. All these exceeded the level 1 National Standard. The one-week consecutive motoring results demonstrated that the noise pollution suffered by the residents living in North Zone and East Zone was a long-standing problem. Conclusion: The noise levels in North Zone and East Zone of Jinan University generally exceeded the national standard. The situations will become more and more severe with the continuing increase of motor vehicles.
