DIN EN ISO 10140-2:2010-12

This document specifies a laboratory method for measuring the airborne sound insulation of building products. The test results can be used to compare the sound insulation properties of building elements, to classify elements according to their sound insulation capabilities, to help design building products which require certain acoustic properties, and to estimate the in-situ performance in complete buildings. The measurements are performed in laboratory test facilities in which sound transmission via flanking paths is suppressed. The results of measurements made in accordance with this document shall not be applied directly to the field situation without accounting for other factors affecting sound insulation such as flanking transmission, boundary conditions, and total loss factor.
