Acoustics - Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms - Part 2 : application to light elements when the junction has a small influence
ISO 10848-2:2006 applies to light elements such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can be simultaneous through the test element and via the plenum, if any. With measurements according to ISO 10848-2:2006, the total sound transmission is measured, and it is not possible to separate the two kinds of transmission.

Le présent document spécifie une méthode de laboratoire permettant de mesurer la transmission latérale entre deux pièces des bruits aériens et des bruits d'impact par un plancher surélevé. La grandeur faisant l'objet du mesurage est l'isolation acoustique aux bruits aériens et de choc entre deux salles d'une installation d'essai spécifiée, lorsque les bruits transmis par d'autres voies que le plancher surélevé et le plenum commun est négligeable. Ces grandeurs sont appelées "isolement acoustique normalisé latéral" et "niveau du bruit de choc latéral normalisé".
ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document considers only laboratory measurements. The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2. However, the measured quantities Dn,f, Ln,f and Lne0,f only represent the performance with the dimensions for the test specimens described in this document. ISO 10848-2:2017 is referred to in ISO 10848‑1:2017, 4.5 as being a supporting part of the frame document. It applies to Type B elements as defined in ISO 10848‑1, such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can occur simultaneously through the test element and via the plenum (if any). For measurements made according to this document, the total sound transmission is determined and it is not possible to separate the two kinds of transmission.
