Building acoustics - Estimation of acoustic performance of buildings from the performance of elements - Part 3 : airborne sound insulation against outdoor sound

ISO 12354-3:2017 specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a façade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the façade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately to the results from field measurements in accordance with ISO 16283‑3. Calculations can be carried out for frequency bands or for single number ratings. The calculation results can also be used for calculating the indoor sound pressure level due to for instance road traffic (see Annex E). ISO 12354-3:2017 describes the principles of the calculation model, lists the relevant quantities and defines its applications and restrictions.

Building acoustics - Estimation of acoustic performance of buildings from the performance of elements - Part 3 : airborne sound insulation against outdoor sound

Le présent document spécifie des modèles de calcul permettant de déterminer l'isolement acoustique au bruit de choc entre des locaux à partir, soit de données mesurées de caractérisation de l'élément structural, soit de méthodes théoriques de propagation des sons. Par déduction on arrive à un modèle simplifié avec un domaine d'application limité, qui donne directement un indice d'évaluation à partir de celui des éléments. On trouvera les grands principes de calcul, la liste des grandeurs significatives, les applications et leurs limites.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
