3/4” OSB board is better than 5/8” gypsum board. Sound control is measured in STC ratings (sound transmission coefficient). Gypsum board is not as good as OSB board.
Does soundproof drywall work?
If you’re planning a construction project where noise control is important, you might be facing the choice between using multiple layers of standard drywall and buying very expensive “soundproofing drywall.” Does soundproofing drywall work and is it worth the cost?

What type of drywall is soundproof?
There are various drywall types, but the Type X drywall is the most commonly used for soundproofing. It is a fire-resistant board, and a board of 5/8″ thickness can resist fire for an hour, which concurrently makes it the best drywall to reduce noise.

Does 2 layers of drywall for soundproofing?
Double Drywall benefits
The benefit of a double thickness of drywall with Green Glue sandwiched between is less noise penetration. The drywall adds mass, which prevents sound wave penetration, especially lower frequency, and the Glue absorbs sound vibration-damping sound vibration movement.
How much does QuietRock 530 cost?
The QuietRock 530 (5/8″) can be found for a little over $100 per sheet.

How much STC does Green glue add?
10 STC points
Green Glue transforms the sound isolation of common wood stud walls from poor to excellent. For walls of the same weight in this comparison, Green Glue adds 10 STC points and improves low frequency performance by as much as 12 dB.
What is the highest STC rating?
The STC rating goes all the way up to 65. Most products don’t promise anything above 55 and even at a rating of 60, it still doesn’t guarantee complete soundproofing. Nothing is completely soundproof. You cannot stop outside noise completely from entering your space.
