AbstractIn 1995 the IRC Acoustics Laboratory completed a study of sound transmission through gypsum board walls. The results were reported in IRC-IR-693, Summary Report for Consortium on Gypsum Board Walls: Sound Transmission Results but provided only STC ratings. The project was supported by a consortium including Canada Mortgage and Housing Corporation, Canadian Sheet Steel Building Institute, Cellulose Insulation Manufacturers Association of Canada, Forintek Canada, Gypsum Manufacturers of Canada, the Institute for Research in Construction of the National Research Council Canada, Owens Corning FiberglasCanada Inc., and Roxul Inc. This report represents an extension of IRC-IR-693 by providing detailed one?third octave band transmission loss data, physical specifications of the materials used, and construction details for each wall tested. Besides the 285 walls reported in IRC-IR-693, an additional 65 measurements have been included. Although some of the specimens were chosen by individual clients to demonstrate the performance of specific products, these were combined with a structured series establishedcollectively by the consortium. The combined set of 350 specimens provides the basis for a broad general evaluation of sound transmission through gypsum board wall systems.
