DIY Soundproofing | How to Soundproof Your Space

Looking to keep sound in — or out? Try DIY soundproofing!

For a number of reasons, many people would like to soundproof a room in their home. Whether it’s a loud teenager and their almost-famous band, or a game room rocking surround sound, or even just an office that requires a little peace and quiet for the work-from-home parent, most people like to have some control over the decibel levels of their domain. And, like most DIYers, the best kind of project is an effective one that is also affordable.

Pick the right room. If you have a choice of which room to soundproof, consider one on the top floor (if you have more than one floor), since it is difficult to soundproof the ceiling. Choose a room farthest away from noise and appliances. If the walls of the room are unfinished, like a garage, you’ll need to add insulation and drywall.

Step 2

Clear the room. Remove all wall decorations along with any furniture that is not essential. Sound moves best on flat surfaces, so remove any tables, bookshelves and cabinets. If the room has a closet, decide whether to soundproof the doors or remove them and soundproof the closet walls.

Carpet the floor and ceiling. Thick shag carpet is an ideal sound absorber. You have to walk on the floor so make sure it remains flat and even! The floor and the ceiling should be the only flat surfaces in your room.

Cover all windows with cardboard (or fiberglass) and insulation. If possible, use fiberglass or drywall over the windows.

Step 5

Eliminate all flat surfaces and replace with uneven surfaces by applying carpet to the walls in a wave pattern. This will trap sound waves. Cut carpet into equal size squares (6 inches will do), and cut cardboard squares the same size and cover them with carpet. Staple the squares to the wall so they jut out into the room. If the mini carpet walls are placed close enough together, the sound will bounce between the walls and dissipate.

Soundproof the door. Cover the inside of the door with carpet (but leave room for the door knob!). Apply weather stripping until the door fits as snugly as possible into the frame.
