If it is cleaned by hand, it will cost a lot of labor and resources to fully use it. Due to the large area of the sound barrier, the traffic noise it can bear can meet the environmental noise standard. However, such a provision is ideal. In today's golden cities, more and more highways are located within tens of meters of villages and residential areas. Therefore, road operators must take noise reduction measures to reduce the receiving noise in the city. Noise barriers in residential areas are close to noise sources, easy to organize and structure, and occupy a small area and are economical. The shape of the structure is determined according to engineering and environmental requirements, and the sound-absorbing composite structure adopts integral parts.

The sound barrier has the advantages of saving the ground, obviously reducing noise, and being able to be installed and disassembled. Some buildings or walls facing the street also become obstacles to the houses behind. The color of the upper bend sound barrier can be customized. The color of our sound barrier is national standard. At present, the upper arc sound insulation products have been widely used. There should be no consequences. Regardless of the weather, the sound barrier will not be affected.

Especially in some remote areas with underdeveloped economy, the concrete steel bars may be damaged and stolen during transportation. In addition, the sound barrier made of metal screen material is located on the side of the road. Therefore, the anti-theft design of this kind of sound insulation material should be frequently designed for daily inspection, replacement and maintenance, and some special installation situations will inevitably be encountered during the installation of the sound barrier. In the design and construction, attention should be paid to cooperation with special points such as the structure and installation of bridges and sewers along the line.

At present, regarding the problem of traffic noise control, the first thing to consider is the use of sound barriers to solve the problem. Sound insulation barriers are divided into sound insulation reflective pure sound insulation barriers and sound insulation barriers composed of sound absorption and sound insulation. The latter has better sound insulation effects. Based on years of practical experience in the research and design of sound barriers, the author tried to provide practical methods and empirical formulas for the previous parameters in the design of sound barriers for reference by designers.
