摘　　要：在2013年10—12月期间,选取了广州市58条道路和20栋噪声敏感建筑物进行噪声监测,与2011—2012年监测数据相比较,综合分析了广州市道路交通噪声的现状和变化规律。分析表明:广州市昼夜道路交通噪声以71 d B和70 d B为中心上下波动。对于2013年监测数据,噪声敏感建筑物昼夜噪声均值为65.1 d B和64.6 d B,夜间最大突发噪声均值为80.7 d B。此外还计算了每条道路的昼夜噪声频率重心,结果显示,广州市道路昼夜交通噪声频率重心分布基本相同,以1 000~2 000 Hz最为集中。58 roads and 20 noise-sensitive buildings were measured between October and December 2013 in Guangzhou.Compared to the data from 2011 to 2013,the variation of traffic noise in Guangzhou was analyzed. The results showed that the road equivalent noise pressure level fluctuated around 71 d B in the daytime and 70 d B at night. For the data measured in2013,the average equivalent noise pressure level beside the noise-sensitive buildings was 65. 1 d B in the daytime and 64. 6 d B at night. The average value of maximal burst noise at night was 80. 7 d B. In addition,the frequency gravity center of every road was calculated,and the distributions of day and night frequency gravity center were basically the same with the highest concentrations from 1 000 Hz to 2 000 Hz.
