This document specifies calculation models designed to estimate the airborne sound insulation between adjacent 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.<\/p>\n

A detailed model is described for calculation in frequency bands, in the frequency range 1\/3 octave 100 Hz to 3 150 Hz in accordance with ISO 717-1, possibly extended down to 1\/3 octave 50 Hz if element data and junction data are available (see Annex I); the single number rating can be determined from the calculation results. A simplified model with a restricted field of application is deduced from this, calculating directly the single number rating, using the single number ratings of the elements; a method to determine uncertainty is proposed for the simplified model (see Annex K).<\/p>\n

This document describes the principles of the calculation scheme, lists the relevant quantities and defines its applications and restrictions.<\/p>\n
