With the rapid development of high-speed railway and urban rail transit, the problems of vibration and noise become more and more prominent. The noise mitigation of traditional vertical sound barrier is obvious on wheel rail noise, but it is insufficient when the train speed exceeds 250 km/h. Therefore, fully enclosed sound barrier is pushed the construction alongside high-speed railway. In recent years, steel bridges or steel-concrete composite bridges have gradually been widely applied in high-speed railway and urban rail transit. Steel bridges or steel-concrete composite bridges have greaterer sound radiation ability, wide spectrum, large amplitude and difficult to control. Therefore, it is urgent to solve the noise radiation issue when steel bridges or steel-concrete composite bridges are built in environmentally sensitive areas. Focusing on the two study directions of "noise reduction performance and dynamic characteristics of high-speed railway sound barrier" and "vibration and noise reduction of steel bridge", the research trends and development trend of this direction are briefly reviewed in this article.
