AbstractThis paper reports results from continuing studies of sound transmission between adjacent units in wood-framed multi-dwelling buildings conducted at in the Flanking Transmission Facilities at IRC/NRC. The paper examines how common construction details affect structure-borne (flanking) transmission between adjacent rooms. Previous reports from our multi-year experimental study showed that the dominant flanking path between horizontally, vertically and diagonally separated rooms typically involved the exposed surface of the floor. This paper reports on the most recent study, which revealed that there are a number of other transmission paths involving the sidewalls, and ceilings, which become collectively important once the more obvious paths are addressed. Estimates of the apparent sound insulation were obtained by summing the energy transmitted directly through the separating wall or floor assembly with that for all the flanking paths involving the wall/floor/ceiling surfaces abutting the separating construction. These estimates provide the basis for a design guide [ ] to predict sound isolation in typical wood-framed row housing or apartment buildings.
