摘要
为了从路面与车轮接触方面研究如何降低交通噪音,文章从声学基础概念入手,结合人耳听觉特性,从现场测量和实验室测量两方面对轮胎噪音的声学特性进行了分析,最后得出低噪音路面设计中几个重要指标的建议取值。
In order to study from the contact of pavement with wheels how to reduce traffic noise,the paper analyzes the acoustics characteristics of tyre noise in two aspects such as measurement on the site and measurement in laboratory in combination with the characteristics of hearing sense of human ears starting with acoustics foundation conception.At last,it gets value suggested from some important targets in the design of low noise pavement.
