AbstractStructure-borne sound transmission across a cross-junction of double solid timber walls with a solid timber floor was analyzed in a recent research project. Both, the double walls as well as floor slab, were of so-called Cross Laminated Timber (CLT). The floor slab was continuous across the junction for structural reasons and thus, formed a sound bridge between the elements of the double wall. To gain a better understanding of the contributions of sound transmission between the wall and floor elements from the different possible paths, a thorough analysis was conducted. Hereby, direct sound transmission through, and radiation efficiencies of, the CLT elements were measured in a direct sound transmission facility; as well as, structure-borne sound transmission between CLT elements was measured on a junction mock-up. The experimental data was used as in-put data and for validation of the engineering model of EN 12354/ISO 15712 for the prediction of flanking sound insulation in buildings. The test procedures, analysis and results of this research project are presented here.
