44th International Congress and Exposition on Noise Control Engineering, August 9-12 2015, San Francisco, California, USA
In a recent study at the National Research Council of Canada, the direct airborne and impact sound insulation of steel-framed floors were investigated. This study forms one part of a project focusing on the direct and flanking sound transmission in lightweight steel-framed buildings for mid-rise constructions. Mid-rise constructions (4 to 6 stories) using lightweight steel framing are becoming more and more common in North America. The floors investigated in this study consisted of 38 mm lightweight gypsum concrete on a corrugated steel deck, fastened to steel joists with a gypsum board ceiling. The parameters investigated included the joist depth and the configuration of the ceiling. In addition, the influence of various floor coverings was examined. The airborne sound transmission loss was measured according to ASTM E90, and the light impact sound insulation was measured according to ASTM E492. The results are presented and discussed.
