outdoor sound barrier， external sound insulation， Sound barrier The sound insulation barrier with curved steel structure at the upper corner has a firm and reliable barrier geometry, large absorption capacity and sound insulation characteristics of the screen itself, and has a longer service life. Longer than traditional noise barriers. It can be used in areas with poor natural conditions and strong weather resistance, and can be equipped with doors and windows according to actual needs. It is widely used in electrical, chemical, paper, medicine, steel, municipal, real estate, manufacturing and other fields. In the energy industry, the noise reduction effect of the main transformer is good and the effect is satisfactory.

outdoor sound barrier， external sound insulation， Sound barrierNoise pollution to the environment has become a worldwide problem. Effective prevention and control of noise pollution on both sides of the main line is not only a major environmental issue, but also a hot issue of social concern. There are more and more high-rise buildings in major cities in China, and the problem of railway noise passing through urban areas is becoming more and more important, which can save design costs and reduce conflicts between building construction. Railway and urban master planning, land use planning and environmental protection planning. The prevention and control of railway noise pollution generally adopts three methods: sound source control, sound propagation path control and sound receiving point protection.
