It can be used for noise control of urban light rail, viaduct, underground tunnel, mechanical equipment and improvement of acoustic room, multi-function hall and other indoor sound effects.The sound-absorbing aluminum foam is pasted to concrete or steel structure, and erected on both sides of viaduct and light rail as large sound-absorbing wall, which can reduce urban traffic noise.The Aluminum foam panel with sound insulation can be used for noise isolation in factory room, machinery equipment and outdoor construction site, which solves many limitations of glass wool, asbestos and other sound absorbing materials Aluminum foam panel widely used at present.
