| Abstract | This paper reports findings from a recently completed study of flanking sound transmission involving the wall/floor junction in wood framed buildings. The paper examines how common construction details affect flanking paths between rooms separated vertically by a floor/ceiling assembly. Variables considered include: the mounting conditions and orientation of joists, the framing of the wall assembly, and the mounting and number of layers of gypsum board. Estimates of the apparent sound insulation were obtained by summing the energy transmitted via the direct path through the floor-ceiling assembly and all the flanking paths involving four wall-floor junctions. Results indicate that if there is no floor topping (i.e., the subfloor is bare) then it is quite likely that the apparent sound insulation for both airborne and impact sources will be limited by flanking. Three different toppings are considered as treatment options for the floor, and additional layers of gypsum board and resilient mounting are considered as options for the walls. The effectiveness of each option is considered and discussed. |
