Developing a guide for Flanking sound transmission in wood framed construction

AbstractA subset for airborne sources and horizontal transmission, applied to wood-framed constructions, with the wall and floor assemblies, is presented. The estimates of the apparent sound isolation are obtained by summing the energy transmitted directly through the separating wall or floor assembly with the flanking paths involving wall. Most of the sound is transmitted via the floors and other paths such as ceiling or the abutting side walls. The gypsum board ceiling is generally mounted on resilient channels, which reduces flanking transmission through the path significant to them. Flanking through an abutting side wall transmits less sound, which could also limit overall performance provided the separating wall and the floor are improved. This experimental characterization of the direct and flanking sound transmission paths in wood-framed construction can lead to a manageable set of path transmission terms.
