Requirements for soundproof materials
Dec 19, 2018

For soundproof materials, to reduce transmission sound energy, block the spread of sound, it can not be as porous, loose, breathable as sound-absorbing materials; On the contrary, its material should be heavy and dense, such as lead plate, steel plate and other materials. The material requirements of soundproof materials are dense without pores or gaps, and have a large weight. Because this kind of sound insulation material is dense, difficult to absorb and through the sound energy and reflection can be strong, so its sound absorption performance is poor.
