Abstract
EN 12354 gives a model for the prediction of sound transmission between adjacent dwellings that can be applied in the stage of design of the building. The model takes also into account first order flanking paths and was originally developed for homogeneous monolithic structures (e.g. concrete or masonry). However, more and more lightweight building elements (e.g. joist floors and gypsum board walls) are used in Europe and hence it is desirable to include this type of construction and ensure the approach and assumptions of En 12354 are consistent with the vibration response of lightweight building structures. Thus in a recent research project a statistical energy analysis (SEA) framework is applied to predict flanking sound transmission through gypsum board walls. In this paper the SEA model and the acquisition of some necessary input data are briefly reviewed. Further the validity as well as the limits of the SEA model are discussed and finally conclusions are drawn for a standardization of the model in the context of EN 12354.
