Building acoustics. Estimation of acoustic performance of buildings from the performance of elements - Airborne sound insulation against outdoor sound1 Scope This document specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a faade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the faade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately to the results from field measurements in accordance
