Building acoustics. Estimation of acoustic performance of buildings from the performance of elements - Impact sound insulation between rooms1 Scope This document specifies calculation models designed to estimate the impact sound insulation between rooms in buildings, primarily using measured data which characterize direct or indirect flanking transmission by the participating building elements and theoretically derived methods of sound propagation in structural elements. A detailed model is described for calculation in frequency bands, in the frequency range 1 3 octave 100 Hz to 3150 Hz
