| Abstract: | The edge-modified noise barriers are based on its unique acoustic structure to reduce the influence of the diffraction sound.In order to improve the overall reduction effect of noise barriers,the edge-modified noise barriers are the important and necessary supplements of upright type noise barriers.The noise reduction principle of the edge-modified noise barriers is analyzed,and the recent technical development is introduced. |
