摘要
目前尚无铁路声屏障声学设计和测量规范。用插入损失法对芜湖至火龙岗左绕行线声屏障工程降噪效果进行了测量及评价。监测结果表明,该声屏障工程取得了明显的降噪效果,达到设计要求。
The reports that noise barriers is used in the pollution harness of railway noise is fewer in China. There isn＇ t on acoustical design and measurement of the railway noise barriers at present. The article introduced the efficacy measurement and evaluation using insertion loss method to the engineering of noise barriers from Wuhu to Huolonggang.
