With the continuous expansion of urban construction, the continuous development of transportation construction, and the continuous increase in traffic volume, the solution to the problem of urban road traffic noise is imminent. However, since it is not realistic to achieve noise reduction effects through large-scale greening and tree planting, urban road projects often use sound insulation and noise reduction barriers to reduce noise. The metal microporous sound barrier is a screen style with relatively good sound insulation and noise reduction effects, and is usually used on viaducts, high-speed railways and other traffic roads. The following is an introduction to the material specifications and characteristics of the "metal microporous sound barrier", I hope it will be helpful to everyone!
