【摘要】 打浦路隧道3#排风塔位于世博会选址范围内,其噪声严重超标。通过采取消声、吸声、隔声等综合治理措施,使3#排风塔噪声对周边环境的夜间影响由65.7dB(A)降为50.2dB(A)。可供其它隧道风塔噪声治理及地铁排风口噪声治理参考。更多还原

【Abstract】 Dapu road tunnel 3# wind-tower is located in the world Expo site, and its noise badly overruns. This paper introduces some synthesis control steps such as noise elimination, sound absorption and sound insulation and so on. And these steps have made the environmental influence of the 3# wind tower reduce from 65.7dB(A) to 50.2dB(A). It can be used to control other tunnel wind-tower’s and subway vent’s noise. [更多还原
