摘要
通过实例，对高速公路交通噪声的污染状况、水平和空间分布规律、噪声随时间的变化以及隔声墙的防护效果进行了分析研讨，同时提出了改善声环境质量的建议。
From a concrete example,this paper studied the traffic noise on expressway including its pollution condition,regularities of horizontal and spatial distribution,and changing regularities with time.At the same time,the protective effects of sound proof walls are searched and some suggestions are provided for it to improve environmental quality.
