AbstractThe primary focus of this project is flanking transmission in wood framed construction caused by continuous structural elements that pass under a partition wall between two horizontally separated multifamily dwellings. The project focus and construction details were decided by a Steering Committeeformed from technical representatives from each of the project partners: Canada Mortgage and Housing Corporation, Forintek Canada Corporation, Marriott International, National Research Council Canada, Owens Corning, Trus Joist, and USG Corporation. Flanking transmission is sound transmission between two rooms by paths other than directly through the nominally separating wall or floor assembly. Flanking exists in all buildings and its importance in determining the apparent sound insulation (that perceived by the occupants) will be a function of the construction details of the walls, floors and their junctions.
