禅城区临近道路高层建筑噪声垂直分布规律分析

Analysis of vertical distribution law of high-rise building noise in adjacent roads in Chancheng District

通过对佛山市禅城区季华路和深华路附近的某高层大厦进行等间隔垂直噪声实测,将各楼层噪声实测结果进行对比分析,得出道路交通噪声在高层建筑物垂向分布受到道路行道树、车体本身和路面的吸声、反射等影响,从而使交通噪声随着高度的增加总体趋势是由小变大再变小,最大噪声级出现在离地面第5-10层高度处。

Through the measurement of equal interval vertical noise in a high-rise building near Jihua Road and Shenhua Road in Chancheng District of Foshan City, the measured results of noise on each floor are compared and analyzed, and the vertical distribution of road traffic noise in high-rise buildings is obtained. Affected by the roadway tree, the body itself and the sound absorption and reflection of the road surface, the overall trend of traffic noise increases from small to large, and the maximum noise level appears at the height of the 5th to 10th floors from the ground. At the place.
