The estimation of acoustical performance of horizontal partitions, from the performance of elements and components using EN 12354 Standard do not actually provides satisfactory results when applied to the floors made by hollow brick and concrete beams, typical of Italian and Mediterranean area building technology. In this paper is reported an overview of measurements performed in situ, independently by different researchers, on various typology of hollow brick and concrete bare floors in several construction sites in different Italian regions. The purpose of this study is to identify an empirical spectrum of normalized sound pressure level of a reference floor realized in hollow brick and concrete in order to provide a useful and simple tool for estimating the noise performance of the most popular building technology of floor in Italy.

Abstract
The estimation of acoustical performance of horizontal partitions, from the performance of elements and components using EN 12354 Standard do not actually provides satisfactory results when applied to the floors made by hollow brick and concrete beams, typical of Italian and Mediterranean area building technology. In this paper is reported an overview of measurements performed in situ, independently by different researchers, on various typology of hollow brick and concrete bare floors in several construction sites in different Italian regions. The purpose of this study is to identify an empirical spectrum of normalized sound pressure level of a reference floor realized in hollow brick and concrete in order to provide a useful and simple tool for estimating the noise performance of the most popular building technology of floor in Italy.Pubblicazioni consigliate
