However, this also brings an inescapable problem-noise pollution. The noise on the road bridge not only affects the life quality of surrounding residents, but also causes adverse effects on the city environment.

[0003] In order to weaken the influence of noise pollution, the sound reduction barrier is widely used in the road bridge. The sound reduction barrier is equivalent to inserting an isolation between the sound source and the receiver, so that the sound wave propagation has a significant attenuation, thereby weakening the noise influence in a certain area where the receiver is located. However, different road widths, different tilting degrees on the left and right of the road, so that when the noise on the road is transmitted to the two isolation belts, the phase angle of the noise is different. The sound reduction plate and the support of the current sound reduction barrier are fixed, and cannot be flexibly adjusted in angle according to different road bridge environments, so that the effect in actual application is greatly discounted, and there is great limitation in use.
