摘要
为了了解路面噪声的产生及声屏障的降噪效果,对噪声产生机理及声屏障的类型进行了分析,并重点阐述了轮胎路面噪声的产生机理和噪声传播过程,同时分析了计算声屏障降噪量的两个公式,并进行了示例计算。
In order to resolve the generation of mad noise and noise reduction effectiveness of noise barrier, the mechanism of noise and styles of noise barrier were analyzed. The tire pavement noise mechanism and transmission process were emphasis illustrated. At the same time, two calculation formulas of noise barrier reduction quantity were analyzed and example calculation.
