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 specifies measurement methods to be performed in a laboratory test facility in order to characterize the flanking transmission of one or several building components. The measured quantities may be used to compare different products, or to express a requirement, or as input data for prediction methods, such as EN 12354-1 and EN 12354-2. This part of ISO 10848 is specifically referred to in ISO 10848-1:2006, 4.4, as being a supporting part of the frame document. This part of ISO 10848 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 this part of ISO 10848, the total sound transmission is measured, and it is not possible to separate the two kinds of transmission. The measured quantities Dn,f and Ln,f depend on the actual dimensions of the test specimen. A light element is defined in ISO 10848-1:2006, Clause 3.
