汽车的噪声属于综合噪声,其影响范围大、干扰时间长、受害人员多,国家环保总局于2002年1月颁布了新的更为严格的汽车噪声控制法规。本文从轮胎噪声产生的原因入手,分析各种沥青路面的降噪机理及其与汽车轮胎噪声的关系,得出阻尼减振式降噪沥青路面是一种比较理想的低噪声沥青路面的结论,以期在施工中能得到推广使用,以便有效地降低汽车的噪声污染。
Automobile noise is a comprehensive noise, the impact of a wide range of long-term interference, victims and more, the State Environmental Protection Administration in January 2002 promulgated a new and more stringent noise control laws and regulations. Based on the reasons of tire noise, this paper analyzes the noise reduction mechanism of various asphalt pavement and its relationship with the tire noise of automobile, and draws the conclusion that the damping and damping noise reduction asphalt pavement is an ideal low-noise asphalt pavement. With a view to promote the use of construction in order to effectively reduce the noise pollution of cars.
