摘要
在广州市内选取了100条道路及18栋噪声敏感建筑物,于2015年11月进行昼夜噪声监测实验,综合分析了2015年广州市道路交通噪声污染现状。分析结果显示:道路昼夜等效声级分别为70.83,70.10 d B,噪声敏感建筑物昼夜等效声级分别为63.47,61.09 d B。昼间快速路、主干路及各类噪声敏感建筑物周边环境的噪声污染较严重,夜间仅12.5%的次干路周边等效声级在标准限值以内。
In order to analyze the road traffic noise pollution situation in Guangzhou,100 roads and 18 noise-sensitive buildings in Guangzhou were chosen to be monitored in November 2015. The analysis result showed that： The equivalent sound level of road traffic noise was 70. 83 d B in the daytime and 70. 10 d B at night; as for noise-sensitive buildings,it was63. 47 d B in the daytime and 61. 09 d B at night. In the daytime,the noise pollution was serious around the express ways,major arteries and noise-sensitive buildings. While at night,only 12. 5% of the minor arteries were with equivalent sound level under the limiting value of China＇s national standard,GB 3096—2008.
