How to Soundproof a Room How to Soundproof a Room
Unwanted sound can make even the most beautiful home a nightmare to live in, and getting a good night's sleep in such a noisy environment can be challenge. Soundproofing one or more rooms can restore that much needed peace and quiet and help you get the rest you need. For a temporary fix, heavy wall coverings like draperies can be hung. For a longer lasting, but visually unappealing solution, sound dampening tiles can be installed on the walls and ceiling. But for for permanent and esthetically pleasing soundproofing, the best way is insulation inside the walls.
These steps are easier if the home is still under construction, but it can still be done if the walls are already erected.
Step 1 - Install Plumbing, Wiring and HVAC
If the walls are still under construction, make sure all the electrical wiring, plumbing and duct work is in place before beginning the soundproofing process.
Step 2 - Hang, Remove or Drill Drywall
Hang drywall on one side of the stud walls in the room that is to be soundproofed. This allows the room to be closed while still allowing access to the interior walls. When choosing the part of the room to leave open, consider such factors as easy access and the lay of the home.
If the room is already constructed, remove the drywall from one side of the walls in the room to be soundproofed. Choose the side which both offers the most working space and causes the least amount of damage.
Another option is to cut small holes in the drywall close to the ceiling between the studs. The space between the drywall can then be filled with blow in paper or expandable foam insulation.
Step 3 - Install Insulation
Apply fiberglass or recycled denim insulation batting to the walls. Unlike for temperature insulation the batting can be packed in tightly, since the tighter the material the more sound will be stopped. When packing the material in. The insulating properties will be diminished by the tight packing, but your goal here is to block sound, not heat transfer.
An alternative to the above is to call in a professional insulation contractor and ask them to blow paper fiber or foam insulation into the open stud bays or through the holes at the top of the wall. This paper fiber or foam will adhere to the construction and provide both high insulation value and excellent sound deadening.
Step 4 - Replace or Repair Drywall
After the insulation is in place, the drywall can be hung as usual or the holes can be patched. Repaint the wall and you now have an invisable solution to a noisy problem.
