Abstract
Sound transmission through building structures often has to be predicted at the design stage to meet legal requirements. So far no standardized prediction model like the one of ISO 15712 that was developed for homogeneous monolithic building structures (e.g. concrete or masonry) exists for the prediction of flanking sound transmission in lightweight building structures (e.g. joist floors and gypsum board walls). Thus in a recent research project a statistical energy analysis framework is applied to predict flanking sound 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 ISO 15712.
