Acoustic classification of dwellings – A growing diversity of sound insulation descriptors in national schemes in Europe
Abstract
Acoustic classification schemes for dwellings exist in several countries in Europe, typically prepared and published as national standards. The schemes define quality classes intended to reflect different levels of acoustic comfort. The main criteria concern airborne and impact sound insulation between dwellings, facade sound insulation and service equipment noise. The schemes have been implemented and revised gradually since the early 1990s. However, due to lack of coordination, there are significant discrepancies, and new standards and revisions continue to increase the diversity in Europe. Descriptors, number of quality classes, denotations, class intervals, total range of classes and class levels vary – as well as the status in relation to regulations. The diversity in Europe is an obstacle for exchange of experience about constructions fulfilling different classes and thus for design and trade. The paper presents an updated overview of acoustic classification schemes in Europe and detailed information about the variety of descriptors applied for sound insulation between dwellings. The implications of interaction – or lack of interaction – between acoustic classification schemes and national acoustic regulations will be indicated and discussed. Finally, the main features of ISO/TS 19488 about acoustic classification of dwellings will be included in the comparative study of national schemes.
