Developing a guide for flanking sound transmission in wood framed construction

This paper reports results from continuing studies of sound transmission between adjacent units in wood-framed multi-dwelling buildings. First, the paper presents some recent extensions of our multi-year experimental study, which has assessed how common construction details affect structure-borne (flanking) transmission between adjacent rooms, for a broad range of wall and floor constructions. Previous reports have focused on the wall and floor surfaces connected at the wall/floor junction - especially the floor surface, which is often the dominant problem. This paper includes a number of other paths that may collectively become significant when more obvious paths are controlled.Ce document fait \ue9tat des r\ue9sultats d?\ue9tudes continues sur la transmission acoustique entre des logements contigus de b\ue2timents d?habitation collective \ue0 ossature de bois. En premier lieu, on y pr\ue9sente certains prolongements r\ue9cents de notre \ue9tude exp\ue9rimentale pluriannuelle, laquelle a jusqu?ici \ue9valu\ue9 comment les d\ue9tails de construction courants influent sur la transmission du son par conduction (transmission indirecte) entre des pi\ue8ces contigu\uebs, et ce, pour une vaste gamme de constructions de mur et de plancher. Des rapports ant\ue9rieurs se sont int\ue9ress\ue9s aux surfaces des murs et des planchers \ue0 la jonction mur-plancher, et plus particuli\ue8rement \ue0 la surface du plancher, qui repr\ue9sente souvent le probl\ue8me dominant. Sont comprises \ue9galement plusieurs autres trajectoires acoustiques qui peuvent collectivement devenir significatives lorsque les trajectoires les plus \ue9videntes sont contr\uf4l\ue9es.Peer reviewed: YesNRC publication: Ye
