Abstract

The estimation of impact sound insulation of horizontal partitions, evaluated from the performance of elements using EN 12354 Standard, do not actually provides satisfactory results when applied to the floors realized in hollow brick and concrete, typical of Italian building technology. Over the last years many comparisons between in situ measurements and empirical estimations have been made, both by Italian Universities and Research Institutes and by professionals and consultants, who have shown indisputably great differences between the results obtained through estimation models and the measured data. 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 the normalized impact sound pressure level of a floor reference realized hollow brick and concrete in order to provide a useful and simple tool for estimate the noise performance of the most popular building technology of floor in Italy.
