Examining different retrofit solutions to enhance airborne sound transmission loss in wood frame wall construction.

摘要

Through laboratory testing we were able to compare different retrofit solutions to increasethe sound transmission class (STC) rating of a base wall assembly. The base assemblyconsisted of a nom 2×4 wood stud spaced 16”OC, R13 insulation (3.5”) and 1 layer of 5/8”Type X gypsum wallboard on source and receiving side. Four retrofit solutions were usedincluding; 1 layer of 5/8” Type X gypsum wallboard, 1 layer of Quiet Rock QR528, 1 layerof Type X gypsum wallboard with Green Glue, 1 layer of Type X gypsum wallboard withGenieClipTM sound isolation clips.
