摘 要: 对杭州市萍水人家住区临街建筑物立面噪声级进行现场实测,得到道路交通噪声竖向上先增后减的传播规律。通过实测数据分析表明:在一定高度内,建筑立面噪声随高度的增加而增加;建筑达到一定高度后,道路可看做线声源,立面噪声随高度的增加而减小。 Through measurements of the vertical noise distribution of street building facade in PingShuiRenJia district, the vertical propagation regularity is verified:noise level going up first and then down with height. The noise level increases under certain height.When the street building reaches a certain height,the road can be seen as a line source,the noise level will attenuate with the increase of height.
