Stud wall design plays an important role in noise transmission from room to room in your home. Staggered stud wall design can help soundproof any area of your home.
Construction begins with a wider than normal top and bottom beam, usually a 2 x 6 or a 2 x 8 instead of a 2 x 4. 2 X 4 studs are screwed in an alternating pattern along the base plate. The studs are spaced 16 inches on center across the beam and two 2×2’s are security each end to support the weight of drywall. This creates form of discontinuous construction. This prevents noise from being conducted from one sheet of drywall, through the studs, and into the next room.
Metal studs can also be used in place of timber to further reduce the conduction of sound vibrations. You may also consider increasing the amount of dead space within the walls to accommodate larger amounts of thick insulating material to help absorb sound. All seams in the drywall must also be properly sealed in order to block out unwanted noise.
Finishing the wall with denser materials such as brick, sheetrock, or plaster can also significantly reduce the noise level that is transmitted from room to room. Double layers of sheetrock can be used with an adhesive layer of glue or silicon caulking in between. By alternating seems out of wall covering, the soundproofing qualities of a room are greatly increased.
Special order thicker doors such as those used in commercial applications may also be needed to prevent sound from being transmitted. Common interior doors are lightweight and have a hollow center. Heavier commercial-grade doors block sound more efficiently. If you are installing double layers of drywall or sheetrock, you may also have to special order thicker doorjambs to accommodate the increased width.
Discontinuous stud wall design is ideal for walls separating the garage and the living space of your home, as well as typically noisy areas such as children’s playrooms and laundry rooms. Incorporating discontinuous stud wall design into areas such as your home office and bedroom can enrich your levels of rest and productivity by keeping out unwanted noise.
Discontinuous stud wall design used in conjunction with double layers of dry wall provides an adequate level of soundproofing for a fraction of the cost of using specially design soundproofing materials. The level of soundproofing achieved by changing the design of the stud walls and selecting denser building materials is usually adequate for the purposes of most homeowners.
