How to Soundproof Drywall

You need special drywall to soundproof a room.

Soundproofing drywall will cut down on the noise emanating from, and entering into, a given room. Drywall is made from gypsum plaster and thick sheets of paper and dried in a kiln. The benefits of drywall are the relative ease of use and the overall clean appearance. One downfall of drywall as compared to the old-fashioned lathe and plaster is that it doesn't act as a strong sound barrier. However, there are ways to soundproof a room with drywall.

Things You'll Need

• Acoustic insulation
• Soundproofing drywall
• Acoustical paint
• Drywall screws
• Phillips screwdriver
• Joint compound
• Putty knife

Instructions

1. Remove any drywall and insulation on the walls and ceiling. You need a clean slate to soundproof the room, so all construction materials must be removed.

2. Install acoustic insulation between all studs and around door and window frames. Insulation is only as good as its weakest point. Leave no gaps or spaces to get the most soundproofing benefits.

3. Install soundproof drywall to act as a second layer of soundproofing. Quiet Rock is the most popular brand of soundproof drywall and can be bought online or through specialty dealers. Installation is the same as with normal drywall; use standard drywall screws and traditional joint compound to finish.

4. Paint both walls and ceiling with acoustical paint for an additional layer of soundproofing. Acoustical paint can be found in most major hardware stores.

Tips & Warnings

• If necessary use expandable foam insulation in hard-to-reach areas. However, this will not be as soundproof as the acoustic insulation.

• No room can be completely soundproof, but the above process will greatly reduce noise.
