摘　　要：在轻轨桥架两侧设置声屏障是控制轨道交通噪声的主要措施之一,对上海轻轨明珠线桥架两侧设置不同高度声屏障实际降噪效果的测量与分析,对声屏障的实用设计有重要的参考价值。It is a main measure to control the noise of light rail transportation by installing noise barriers along two sides of a light rail bridge. Some measurements and analysis of noise barriers with different height along the Shanghai light rail bridge are measured in this article, which can be useful for the design of noise barriers.
