AbstractThe airborne sound isolation between adjacent dwellings in multi-family buildings is often much less than would be expected from the rated sound reduction index R of the nominallyseparating wall or floor, due to structure-borne transmission of vibration at the junctions of wall and floor assemblies. Recent studies have identified key paths for this ?flanking?, or structure-borne transmission, in a range of typical North American wood-framed constructions. A variety of construction modifications to control such transmission have also been evaluated. This paper presents data for horizontal flanking involving typical wall and joist floor assemblies, and shows the effect of some practical modifications that control the key flanking paths.
