摘要
在分析城市交通噪声主要特征的基础上 ,探讨声屏障的声学设计、结构设计及强度设计方法 ,介绍城市高架公路新型声屏障的试验室测试结果和应用情况。测试和应用结果表明 ,这种新型声屏障是城市高架公路控制噪声的有效设施。
Based on the analysis of the main features of municipal traffic noise, the methods of acoustic design, structure design and strength design of acoustic screen are studied. The measured laboratory results of the new type of highway acoustic screen and its application are introduced. It has been indicated that this new type of acoustic screen is an effective means for controlling municipal elevated highway noise.
