Adopting the structural form combined with metal sound-absorbing material foamed aluminum and light-transmitting materials, the development trend of sound insulation barriers in the use of materials is light weight, transparency, good sound insulation performance, high strength, easy installation, and high degree of industrialization in construction. The acoustic performance is good and the building space occupied is small, while meeting the sustainable development requirements such as easy maintenance, no pollution to the environment, and easy recycling.
