What are the soundproofing materials for bedroom ceilings?

Sound insulation should completely block the transmission of sound, so the material of sound insulation requires large density and quality, and it is airtight. Sound insulation can be used in many materials, such as high-density gypsum board · acoustic insulation board and so on. The sound insulation effect is the advantages and disadvantages are directly proportional to the quality of the materials you use, and the greater the quality, the better the sound insulation effect.

There are many materials on the market that can be used for sound insulation, as long as the principle of density is followed, such as sound insulation panels, large density boards. Coupled with a reasonable construction method, there is no problem at all. The general way is to form a cavity in the keel, fill it with soundproof cotton, and then seal the board with a higher density, and then do the surface decoration.

If there is resonance, consider vibration isolation.

Calcium silicate small ceiling, calcium silicate board, mineral wool board, composite sound insulation board, etc.

First of all, we must make one thing clear, there are many kinds of sound insulation materials, and secondly, there are many kinds of ceilings, Jiangsu Sanxian generally recommends contacting a professional sound insulation acoustic company to issue a plan according to the site situation, and then select and install materials according to the plan.
