Where can one find help?
To enable designers, builders, and architects to use the design procedure, NRC has teamed with industrial partners including:
- Canadian Concrete Masonry Producers Association (CCMPA);
- Canadian Institute of Steel Construction (CISC);
- Canadian Precast/Prestressed Concrete Institute (CPCI);
- Canadian Ready Mixed Concrete Association (CRMCA);
- Canadian Wood Council (CWC);
- Gypsum Association (GA);
- Owens Corning Canada; and
- Rockwool.
In co-operation with these and other industry partners, NRC has conducted a significant amount of research by testing and evaluating the sound transmission through different types of building elements and junctions. Figure 4 shows a laboratory setup at NRC designed to evaluate the flanking sound transmission in cold-formed, steel-framed constructions. Figure 5 shows a laboratory setup to determine the vibration transmission on a junction mockup constructed from cross-laminated timber (CLT) elements. Based on these research studies and the input from industry partners, the following tools and guidelines were developed to help with the transition from STC to ASTC.
