Sound insulation panels are also called sound barriers. With the rapid development of highways and railways, the scale of the road network continues to expand, and the noise radiated to the outside of the vehicle increases accordingly. Hospitals, residential areas, campuses and other noise-sensitive areas along the line are more affected. Sound insulation board is a kind of noise barrier that is widely used. The design of road and railway sound insulation board is mainly for better sound reduction. There are many materials for road/railway sound insulation boards, including steel and aluminum. At present, the sound insulation boards that are widely used in the market and have better sound insulation effects are mostly made of aluminum all
Road and railway soundproof aluminum plates are generally produced and selected 5 series aluminum-magnesium alloys 5a03, 5a05 and 5757. 5a03-h36 alloy aluminum plates for road and railway soundproof aluminum plates have good sound insulation, sound absorption, and excellent weather resistance, durability and resistance. High fatigue strength and plasticity, machinability, and good arc welding performance.
