Abstract:
In a recent study at the National Research Council of Canada, the direct sound
transmission loss of heavy gauge steel stud walls was investigated. Midrise
buildings (4 to 6 stories) using steel stud walls are becoming more and more
common in North America. In addition to the steel studs, the walls typically
include bridging channels and steel straps for bracing against lateral and
shear loads. The sound transmission losses of more than thirty of the steel
stud walls were measured in this study. The parameters that were varied
between walls included the stud spacing, stud gauge, stud depth, cavity
insulation, and sheathing. In addition to the standardized transmission loss
tests, structural measurements were performed to investigate the stud
stiffness and other parameters. The results are presented and compared to
other wall types including light gauge steel stud walls and wood stud walls.
