Abstract:
As part of a research project to develop design solutions for concrete-masonry
buildings for the Canadian market, the apparent sound insulation performance
of hybrid assemblies with concrete masonry walls and wood joist floors was
evaluated. In this paper, the effect of junction coupling is investigated in
an ISO 15712 flanking prediction context. Airborne flanking path data
predicted according to ISO 15712 are compared to data measured using the
indirect ISO 10848 shielding method. Recommendations are made on how
appropriate the application of ISO 15712 is for this type of hybrid assembly.
