Sound Insulation Evaluations of Several Single Row-of-Wood-Stud Party Walls under Laboratory and Field Conditions.
Abstract
Adequate party wall design for multifamily dwellings requires a sound transmission class (STC) = or > 45. A standard stud wall consisting of a single layer of 1/2- or 5/8-inch gypsum board directly attached to each side of the studs will give an STC = 32 to 37. If insulation is placed in the stud cavity and at least one gypsum board face is decoupled from the studs, a potential for STC values over 50 can be obtained with double-row-of-stud constructions using a single layer of gypsum board on each side, the added space and material requirements make the single-row-of-stud construction economically desirable. This study evaluates four different types of single-row-of-stud designs under both laboratory and field test conditions. Laboratory STC values for the single layer of 5/8-inch gypsum board constructions ranged from 39 to 47.
