【摘要】 采用现场调查的方法对沈阳市某快速路交通噪声状况进行测试,根据现场调查测试结果分析:噪声强度在快速路两侧高层建筑物的高度分布不同,其随距建筑物横向距离的增大呈衰减特性,其随时间的变化幅度较小,进而对快速路两侧敏感建筑物的噪声防治提出相应对策。更多还原

【Abstract】 Expressway traffic noise condition in Shenyang city was tested by field investigation. The results showed that : the noise in high-rise buildings on both sides of the expressway was different with the height, which had attenuation characteristics with the transverse distance increase and changed with time of smaller amplitude. The corresponding prevention countermeasures for sensitive buildings along the expressway were put forward.更多还原
