    <title language="eng">Measured and predicted sound transmission through a laboratory concrete floor</title>
    <abstract language="eng">The direct sound transmission through a simple, massive, homogeneous building element with and without lining is investigated experimentally and compared with analytical and empirical models from the literature. A 150 mm thick concrete floor and a 100 mm thick floating floor were measured in the floor transmission facility of the National Research Council Canada, i.e. without flanking sound transmission. In addition to the sound reduction index and the normalized impact sound pressure level, loss factors, radiation efficiencies, and mean squared velocities were recorded in the laboratory. The measured data is compared to established models of sound transmission. A focus is placed on the calculation model of ISO 12354-1 (Appendix B), which uses calculated radiation efficiencies and loss factors to predict the sound reduction index of heavy, homogeneous building elements. Some difficulties with the calculation model and the examples in the standard are discussed. In principle, the results in this study show that the calculation model of ISO 12354-1 gives good estimates when the correct input parameters are used. However, deviations between the calculated and the measured loss factors and radiation efficiencies have large effects on the accuracy of the estimates, particularly in the region around the coincidence frequency.</abstract>

    <title language="eng">Apparent sound insulation in wood-framed buildings</title>
    <abstract language="eng">This Report presents the results from substantial experimental studies of sound transmission, together with an explanation of calculation procedures to predict the sound transmission between adjacent spaces in a building with wood-framed walls and floors. This Report presents two types of experimental data for wood-framed constructions: - Test data for direct sound transmission through typical wood-framed wall assemblies and wood-framed floor assemblies, plus a summary of trends for such constructions and references to compilations of additional data - Test data for flanking sound transmission measured following the procedures of ISO 10848 for coupled wall/floor junctions and wall/wall junctions Worked examples for calculating the apparent sound transmission class (ASTC) rating between adjacent dwelling units are presented to illustrate how the experimental data can be applied.</abstract>
