Sound transmission tests are a good barometer of a door product’s resistance to the transmission of sound from one side of the door to the other. Tests are
conducted under laboratory conditions. Actual noise levels achieved in residential or commercial installations will be affected by the design of door selected, the hardware selected, the materials surrounding the door and the quality of installation.
