Building acoustics - Estimation of acoustic performance of buildings from the performance of elements - Part 1 : airborne sound insulation between rooms

ISO 12354-1:2017 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. 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). ISO 12354-1:2017 describes the principles of the calculation scheme, lists the relevant quantities and defines its applications and restrictions.

Building acoustics - Estimation of acoustic performance of buildings from the performance of elements - Part 1 : airborne sound insulation between rooms

Le présent document spécifie des modèles de calcul permettant de déterminer l'isolement acoustique aux bruits aériens entre des locaux, sur la base de données mesurées caractérisant la transmission directe ou la transmission latérale indirecte, des éléments de construction concernés ainsi que sur des méthodes théoriques d'évaluation de la propagation des sons dans les constructions. Par déduction, on arrive à un modèle simplifié avec un domaine d'application limité qui donne directement un indice d'évaluation à partir de ceux des produits. On trouvera les grands principes de calcul, la liste des grandeurs significatives, les applications et leurs limites.
