Is soundproof drywall worth the extra cost? After all, soundproof drywall is much more expensive than regular drywall. Specific drywall for soundproofing is a specialized product that may be worth the extra money depending on the scope and function of your new room.



Soundproofing your room is also good for your overall well-being. Controlling noise in your home will make your home a more peaceful place. It will also allow early birds and night owls to function well in the same house. According to a study by the National Institute of Health, limiting the noise while people sleep will lead to better quality of sleep.


What is Soundproof Drywall?

Soundproof drywall, also known as pre-damped drywall or acoustic drywall, is constructed in a unique way from standard drywall. Manufacturers create standard drywall with a combination of gypsum, clay, and mica between two thin layers of paper.

Soundproof drywall has multiple layers of drywall with a sound-deadening barrier between them. This internal barrier can be viscoelastics or ceramics. Because sound travels along hard surfaces, the internal layer absorbs sound. This makes soundproofing drywall better than multiple layers of drywall for soundproofing.

The most important question people ask when determining if they should use soundproofing drywall is, does it work? The short answer is yes. Piece for piece, soundproofing drywall is more effective at dampening sound than standard drywall.

When deciding which is the best soundproofing drywall to use, it is important to understand the Standard Transmission Class (STC) score of a particular drywall. The STC score was developed in 1961. This number score measures how much sound is blocked by going through a particular material.

Therefore, the higher the score, the more sound is blocked. A soundproofing score of 20 would mean that you could hear almost everything in the next room, but a score of 60 would be an excellent rating.
