Soundproofing a Room

This article is a step by step actual installation guide. For a more in depth understanding into the science of noise reduction browse our articles. Start with our Soundproofing Basics article. Additionally feel free to contact our office, as the only soundproofing company that installs the products we sell for residential and commercial customers, you can be sure that we will be able to understand and advise you on your particular project.

Following is a short description on the basics of how to soundproof a room:

We want to utilize as many of the 4 basic sound control methods as possible. These are; absorbtion, decoupling, mass and damping. Additionally we need good sealing at the outlets and doors.

  • Your walls/ceiling need insulation in them to absorb some sound. That can be accomplished by using fiberglass batt insulation or mineral wool in between the studs if they are exposed (at this time you should first wrap your electrical outlets with acoustical putty pads). Or by pumping cellulose into the walls if your drywall is already in place and you do not want to remove it.
  • You would then want to decouple your drywall from the studs by using resilient sound clips on the face of the studs. If your drywall is already in place and you do not want to remove it you cannot decouple the wall. (We do not recommend decoupling between layers of drywall, see our article on the triple leaf effect). 
  • If you are trying to control footsteps sound coming from above then decoupling the ceiling is a must. For airborne sound (e.g. TV, Phone etc) Damping the walls/ceiling as in the next bullet point can sometimes suffice. Utilizing insulation, decoupling and damping all together gives you the highest jump in performance, usually 30+ STC points over a standard wall/ceiling.
  • The next step would be to dampen your walls, floors and ceilings. This would be a tremendous help as it dissipates any sound waves hitting your walls stopping the sound from traveling through and down your walls. The most cost efficient and effective way to accomplish this is by applying a damping compound like Green Glue in between 2 layers of drywall or 2 layers of subfloors. If your sound issues are coming through the walls and you are damping the walls we still strongly recommend adding a 2nd layer of drywall and Green Glue to your ceiling as well as sound can flank over your walls and come through your ceilings. This is a must in situations where there is an open air space above both rooms e.g. an attic.
  • Next be sure to use a solid wood door for your doors. Then install a half inch piece of MDF over the door with Green Glue Compound sandwiched in between. The jambs and headers should be sealed with door gasketing, most importantly the large gap at the bottom of the door needs to be sealed with an automatic door bottom. For detailed instructions read our How to Soundproof a Door Article.
  • Finally be sure to seal the perimeters of your walls and ceiling with a proper acoustical caulk. In addition seal around all electrical outlets and add an acoustic electric box seal.
  • Many times you're stuck in a condo or in a situation where you cannot really do any construction. If you have or are planning to put down carpet then take a look at our premium carpet underlayment this product can make a substantial sound reduction change in your room.
  • A final issue that comes up many times is the sound travelling in a home itself e.g. someone talking on the first floor can sometimes be heard in a bedroom on the 2nd floor. This is usually a problem in newer homes where the style is to use hardwood and tile throught the home with wide open foyers and a modern sleek look that minimizzes curtains and oversized furniture. This type of design will cause sound to reflect of the hard surfaces and easily (nd loudly travel throught the home). One solution is to soundproof your door paying special attention to the gap at the bottom as above. Another huge help that will create a general quiet thruought a home is to use acoustical panels. You can order panels in virtually any color/design fabric to match your decor (you can even have custom panels with your own photos paintings etc). These panels are then hung in your hallways and other stratigic locations to absorb sound waves and stop them from echoing off your walls.

Let's face it in this hectic world, our sleep is more important than ever. It's during our sleep when our body recovers from the daily stresses of the day, fights off illness and relaxes before revving up for another schedule-packed day. If you want to reclaim your sleep without having to move to the middle of an isolated field, then invest in soundproofing your bedroom. Soundproofing isn't as expensive as it may sound. With just a little forward planning, you'll be able to get the sleep that you deserve and at a price that won't break the bank!
