Anonymous users2024-01-24To be honest, there is a little sound insulation effect, in fact, the foam color steel tile ceiling only plays the role of heat preservation and heat insulation.
The sound insulation effect of the soundproof ceiling is relative, and it is impossible to completely isolate the sound after installing the soundproof ceiling. Because there are many ways for sound to come from, it can be transmitted from windows, doors, etc., or it can be transmitted through vibrations.
Regarding the sound insulation of the ceiling, it needs to be solved according to the height of the floor, because the general upstairs walking sound is low-frequency noise, which has strong penetration, and in direct contact with the floor, the solid sound transmission is very serious, so it is very difficult to do sound insulation, and it is difficult to completely reduce noise. Now the more scientific and reasonable solution is to make elastic soundproof ceilings.
Make a flexible cushion around the indoor unit, and add a flexible gasket to the fresh air duct mouth, which is not a problem of sound insulation, but a problem of noise reduction.
It is recommended to make a gypsum board ceiling, hang 8 cm down on the basis of the original roof, and fill the middle with soundproof cotton, which can effectively insulate sound. It costs about 40 yuan for one square meter of labor, and the material is not expensive! You should be relieved that the guerrillas will do this work, and the workers who begin their apprenticeships will have the ceiling. >>>More
