How to Keep Noise Under Control
Too much noise is a nagging environmental problem that can be every bit as objectionable as cold air drafts or low indoor air quality. Noise from an outdoor source–a nearby freeway or construction zone, for example–is one kind of problem, but what about sound that originates inside the house?
Car would like to build in effective sound control in his house so noise generated in one room doesn’t spread throughout the house. The need to contain sound is certainly something many of us can relate to, whether the problem is a loud television or Aunt Betsy’s collection of opera classics.
Those responding to Car’s post offer a variety of suggestions, including the addition of a second layer of drywall, the use of specialized building materials, and sealing up all potential pathways for the transmission of sound.
But as GBA technical director Peter Yost argues, an effective solution means a coordinated use of techniques and building materials to create complete wall, floor and ceiling assemblies.
Sound control in walls and ceilings begins with mass and de-coupling.
