| 摘 要： | 通过对福州五一南路一侧的鸿雁大厦30层进行噪声实测,将道路交通噪声实测结果与预测值进行对比分析,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9层高度处.因此城市交通噪声垂向上的声场分布规律难以用导则推...

| Abstract: | A typical high building named Hongyan with 30 layers,located on the eastern side of Wuyi Nan road,Fuzhou,is selected as the noise monitoring site.Results show that the road traffic noise begins to increase and then decrease while the high increased in the vertical distribution,and the noise is at its maximum level when height is the ninth floor under the influence of absorption,reflection of avenue trees,car-body itself and road surface.Therefore,it is concluded that the recommended forecasting model can no... |
