technical field

With the development of the economy, the urban transportation industry is expanding day by day. The large-scale light rail and road construction and the use of transportation equipment in the city not only consume a lot of energy, but also cause unbearable noise and dust hazards to the surrounding citizens. In response to this environmental phenomenon, many main roads in residential areas have installed sound barriers, but high-rise residents around the roads are still suffering from noise hazards.
