However, trains on railways also generate a lot of noise during rapid operation, especially when running in urban areas or near villages and towns, which will have a serious impact on the normal lives of surrounding residents. In order to reduce railway noise, sound barriers are often used to block noise. With the development of science and technology, transportation facilities are gradually shifting towards multifunctional and intelligent trends. Railway sound barriers should not only play the role of sound absorption and sound insulation, but also have more practical functions. The existing road sound barriers have relatively single functions.
