When the whole family’s home, it can get pretty loud. What can you do for noise control between rooms? Well, it depends on whether you need to absorb, block or break the noise.


Listen to BOB VILA ON SOUNDPROOFING, or read text below:

Sound absorption dampens sound waves by converting them into weaker energy. You can add specially-designed sound attenuating batt insulation in interior walls. Carpets, upholstered furniture and acoustical ceilings also help with sound absorption in big open areas.

Blocking sound requires a barrier with enough mass to stop the air movement caused by sound waves.  But if you don’t have concrete walls, you can block noise by using acoustical caulk in all gaps or doubling the drywall.

Breaking the path of the sound means removing the points of contact between the inside and outside so sound doesn’t reverberate through the structure. Acoustic wall studs or a layer of foam under the flooring allow the inner surface to float and isolate the noise.
