Sound-absorbing and noise-reducing coatings
In general, the noise of buildings mainly comes from two forms: impact sound and air sound, and the noise generated by impact mainly vibrates through collision with the floor slab and then spreads from the air to the surrounding area. Therefore, in particular, the impact noise of places such as bars, KTVs, and crowded stadiums will be more serious. The sound-absorbing and noise-reducing coating can be sprayed on the roof, which can well reduce the vibration and thus reduce the impact sound, which is also a new sound-absorbing material to solve the noise of the building floor.
