Ceiling paste extruded polystyrene board, and then hang fiberglass scraping crack mortar, and then do decoration, sound insulation according to polystyrene board thickness, can have effect.
In their own sound insulation ceiling, the use of keel overhead, with the use of sound-absorbing cotton, noise insulation or noise board and other sound insulation materials, reduce the noise downstairs noise down (for upstairs can not handle this method to do more)
A method can be taken in the upstairs to do noise insulation layer, this method can effectively reduce the ground crash sound with the air, and now some domestic real estate developers have been in the construction phase of the floor to do the floor noise treatment.
