@article{Byrick_2011, title={Examining airborne sound transmission loss in various wall constructions}, volume={39}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/2404}, abstractNote={A study that is intended as a guide to better design and construct wall assemblies that meet and exceed minimum code for multifamily dwellings is presented. Two types of framing were used in an attempt to decouple the gypsum board from the structural studs. The first was a 12.5mm Dietrich single leg RC deluxe resilient channels with dog bone slots. These were attached to the studs and oriented horizontally with the resilient leg above the screw leg and spaced 610mm O.C. The double stud construction yielded the highest transmission loss results at low frequencies and the highest overall STC. The decoupled wall is much more effective than simply adding mass. Doubling the drywall only produced a 4dB increase, while creating a decoupled second row of studs and top and bottom plates produced an increase of 24dB.}, number={3}, journal={Canadian Acoustics}, author={Byrick, Wilson}, year={2011}, month={Sep.}, pages={48–49} }
