TM Soundproofing Soundproofing a Room

Soundproofing a Room

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!

This article is a short step by step installation guide, in each step we will link to an article that is more detailed for each specific step.

There are 4 basic sound control methods and we want to utilize as many as possible. These are;

  • Absorption
  • Decoupling 
  • Mass 
  • Damping 

Additionally we need good sealing at the perimeters, outlets, doors and windows.

Step 1 Walls & Ceilings: 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 regarding 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 paragraph can sometimes suffice.

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.

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.

Utilizing insulation, decoupling and damping all together gives you the highest soundproofing performance, usually 30+ STC points over a standard wall/ceiling.

  • If you want even better soundproofing and are doing new construction or you are ready to remove the existing walls/ceilings then read our how to soundproof article.

Floor: For new construction, use insulation in floor joists, Joist Gasket Tape on the top of the joists, 2 layers of half inch subflooring with Green Glue damping Compound in between. For more details see our How To Soundproof Article.

If you have existing carpet or you are putting down carpet you can add a 2nd subfloor with GG. If that will not work our Premium Carpet Underlayment is an excellent noise blocker and can be installed in place of carpet pad.

If you have a finished hardwood floor and would like to stay with that, then there is not much you can do other than working on the ceiling below.

Doors: Doors are thin/hollow and have gaps all around allowing for lots of noise penetration. to treat your door properly, first off use a solid wood door for your doors. Stuff and caulk between the frame ans wall. Then install a sound proof door panel which will beef up your door and seal the gaps at the edges. Alternatively use a  half inch thick MDF board 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 a sound rated automatic door bottom. For detailed instructions read our How to Soundproof a Door Article.

Windows: Windows are another weak link in the room envelope in regards to sound. Installing a 2nd window behind/in front of your existing window is a big help although not that practical in many instances. If you do not have a need to open or close the window you have the option of installing our soundproof window lite kit which is an excellent kit providing a strong seal at the edges easy installation and allows for you to add tour own thick pane of glass.

Another practical very good solution for windows is to use a sound (and light) blocking sound barrier curtain. We custom size your curtain and it is available in a variety of colors. Installation can be done with velcro or with grommets and pegs.


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 throughout the home with wide open foyers and a modern sleek look that minimizes curtains and oversized furniture. This type of design will cause sound to reflect of the hard surfaces and easily (and loudly travel throughout 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 throughout 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 strategic locations to absorb sound waves and stop them from echoing off your walls.

As you can see, sound control doesn't have to be complicated if you have the right soundproofing products.
