Not so long ago, the National Research Council (NRC) completed a study of sound transmission through gypsum board walls. This project was supported by several corporations including Owens-Corning Canada Inc.

The NRC report concluded that glass fiber is equal to, or better than, mineral wool for noise control.


Increasing Mass

Heavier materials block sound better than light materials. For example, adding another layer of gypsum wallboard provides increased sound transmission loss.

Breaking Vibration Paths

Walls transmit sound vibrations from one face to another through structural elements such as metal or wood studs. An effective technique is to stagger wood studs, reducing sound transmission through them. Resilient metal channels can also be used between the gypsum wall board and the stud to break the vibration path. Metal studs are more resilient than wood studs and reduce the transmission of vibrations between one wall surface and the other.

Cavity Absorption

The sound transmission loss of a wall can also be noticeably improved by filling the wall cavity with sound absorbing material such as FIBERGLASS PINK Insulation. The key point to remember is that the insulation is absorbing sound. Within the range of 0.60 to 6.00 pounds per cubic foot for cavity insulation there is no difference in the sound absorbing properties.
