| 摘 要： | 通过在4城市对132条道路进行了道路交通噪声测点高度试验,系统分析了测点高度从手工监测的1.2 m向自动监测的4.5 m转化后,在不同道路情况对道路交通噪声监测数据的影响。结果表明,测点高度提高后监测结果变化在±3 dB(A)以内。待测道路的车道数和测点与机动车道的距离是其主要影响因素。对两测点高度进行对比,4.5 m高度噪声值随水平距离增加衰减较小,测量结果更稳定。

| Abstract: | With the conversion of road traffic noise monitoring from manual to automatic, the measuring-point height increased from 1.2 to 4.5 m. This research has experimented on 132 roads in four cities, systematically analyzed the influence of raising measuring-point height on noise monitoring data in various road conditions. The results show that noise monitoring results change within ± 3 dB (A) after raising measuring-point height. The number of lanes and the distance between measuring points and motor vehicle lanes are the main influencing factors. Comparing the two measuring-point heights, at 4.5 m the noise lever attenuates more slowly with horizontal distances, thus the measurement results are more stable. |
