摘要
对广州市59条不同类型道路和16栋不同功能区噪声敏感建筑物设置监测点进行噪声监测,综合评估广州市道路交通噪声的污染情况。经过分析可知,白天道路噪声均值为72.0 dB,晚上均值为71.0 dB,其中快速路和主干路噪声值较高,次干路和支路较低。对于16栋噪声敏感建筑物,其昼夜环境噪声均值分别为68.4 dB和67.4 dB,夜间最大突发噪声均值也高达82.3 dB。
In order to obtain the total pollution level of traffic noise in Guangzhou, 59 roads and 16 noise-sensitive buildings were monitored. The roads were classified by different types and the noise-sensitive buildings belonged to different noise environment functional areas. The results showed that the average equivalent sound level of roads was 72.0 dB in the daytime and 71.0 dB at night, of which the sound levels of the express ways and major arteries were higher than those of minor arteries and branch ways. For the 16 noise-sensitive buildings, the average equivalent sound levels were 68.4 dB and 67. 4 dB in day and night, and the average value of maximal burst noise was 82.3 dB at night.
