Sound Transmission Loss of Masonry Walls: Twelve-inch Lightweight Concrete Blocks with Various Surface Finishes

As part of a long-term study of the sound transmission of masonry walls, tests were done on six variations of a basic 12-inch lightweight block wall. The variations were to study the effects of several different surface sealing arrangements, including latex paint, plaster and plasterboard. The plasterboard was fastened to the wall with resilient furring strips, with and without a glass fibre blanket in the furring space.Dans le cadre d'une \ue9tude \ue0 long terme de la transmission du son dans les murs en maconnerie, on fait des essais sur six variantes d'un mur de blocs l\ue9gers de 12 pouces afin de d\ue9 terminer l'effet de diff\ue9rentes m\ue9thodes de scellement de la surface, y compris la peinture au latex, le pl\ue2tre et le placopl\ue2tre. Le placopl\ue2tre est fix\ue9 au mur \ue0 l'aide d'un fond de clouage \ue9lastique, avec et sans fibre de verre dans l'interstice.Peer reviewed: NoNRC publication: Ye
