Abstract
The influence of elastic layers (ELs) at junctions between walls and floor slabs on airborne and structure-borne sound transmission in buildings is investigated. For this aim, we carried out measurements on scale models with ELs at the joints. The results were compared with the predictions of the statistical energy analysis model. This model included the theoretically calculated transmission coefficients for junctions between elastically coupled plates. As a practical application, we analysed the performance of ELs in a model for a real building structure and for various positions of ELs. The work showed that the benefits of the use of ELs depend on the specific situation: the effect can be either positive or negative. In fact, the global effect of ELs is only a change in the distribution of the total energy. If less energy is transmitted into one direction, more energy will be transmitted into the other one.
