Acoustics. Laboratory and field measurement of flanking transmission for airborne, impact and building service equipment sound between adjoining rooms - Application to Type B elements when the junction has a small influence has-digital together with the principles and1 Scope 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 123541 and ISO 123542. However, the measured quantities Dn,f, Ln,f and Lne0,f only represent the performance
