AbstractThere has been a proposal in Canada to increase the maximum allowable height of wood framed construction in the National Building Code of Canada (NBCC) from 4 stories to 6 stories. Design of taller buildings will lead to a change in the details of the walls that have to withstand the higher axial and lateral loads. However, also requirements of other building physics disciplines, one of those being the sound insulation, still have to be met. In the study presented here various assemblies that meet the higher load requirements are compared for direct airborne sound insulation. Parameters that were modified include: sheathing membranes, stud arrangement, stud depth, and resilient channels. Some of the wall design variants that work well structurally have very poor sound insulation properties and most of them require the use of resilient channels to obtain somewhat acceptable sound insulation properties. These and more results will be presented here.
