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 substantial influence Ingestion-build-58320 8 gmx namespace1 Scope ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document specifies laboratory and field measurements of buildings for Type B elements (defined in ISO 108481) when the junction has a substantial influence. Laboratory measurements are used to quantify the performance of the junction with suppressed flanking transmission from the laboratory structure. Field
