Soundproofing existing walls isn't difficult when the right materials are used, and it allows you to keep sounds in one room at a time. Whether you have a small home music studio or you simply like to watch movies loudly, you can soundproof any room in your house without reinforcing the walls.
- Skill level:
Things you need
- Foam soundproofing panels
- Hand drill
- 2-inch screws
Select enough soundproof foam panels to soundproof the room. Measure your walls ahead of time to know how many you need. Foam soundproof panels can be purchased in measurements of 4-by-4 feet and larger. The density is up to you. These panels can be purchased online or in home repair supply shops.
Hold one of the foam soundproofing panels against the wall, in a corner where the ceiling meets the wall. Use a hand drill and 2-inch screws to secure the corners of the soundproofing panel in place.
Place a second soundproofing panel next to the first and secure it. Repeat these steps until you have used all the panels needed. This will leave parts of your walls that are too small to fit panels. Areas like this included places near the door and furniture.
Measure and cut down foam soundproofing panels to fit into the places that are smaller than the full-sized panels. Secure these pieces in the same manner as the others.
Tips and warnings
- As an option to improve the appearance of the room, layer sheets of thin sheet rock panelling over the soundproofed wall.
