Acoustic classification of housing according to ISO/CD 19488 compared with VDI 4100 and DEGA Recommendation 103

In Europe, national acoustic classification schemes for housing exist in about ten countries. The schemes specify a number of quality classes, reflecting different levels of acoustic protection, and include class criteria concerning several acoustic aspects, main criteria being about airborne and impact sound insulation between dwellings, facade sound insulation and service equipment noise. The schemes have been implemented and revised gradually since the 1990es. However, due to lack of coordination, there are significant discrepancies, implying obstacles for exchange of experience and for further development of design tools. Due to the high diversity in Europe, the European COST Action TU0901 ”Integrating and Harmonizing Sound Insulation Aspects in Sustainable Urban Housing Constructions” was established in 2009 with preparation of a proposal for an acoustic classification scheme for housing as one of the main goals. The proposal - based on studies of existing, national schemes and discussions about needs - was approved by ISO/TC43/SC2 as the new work item ISO/WI 19488. A working group was established in 2014, developing further the structure and details. The paper presents ISO/2ndCD 19488:2016 and compares the main characteristics with the German VDI 4100:2012 and DEGA Recommendation 103 with special focus on applicability for the existing housing stock.
