Die Klassifizierung des Schallschutzes DnT,w mithilfe des Schalldämm‐Maßes R'w.

The classification of soundproofing with the measure DnT,w with use of the weighted apparent sound reduction index R'w Buildings must ensure sound insulation appropriate to their use. This sound insulation is regulated by building regulations. In Germany, this is regulated by DIN 4109 Part 1 with a specification of a "minimum sound insulation". Additional requirements are referred to as "increased sound insulation". However, increased sound insulation does not necessarily lead to increased soundproofing. Soundproofing and sound insulation are not equivalent terms in this respect. This article shows that a direct assignment of the quantities R'w and DnT,w is only possible for certain geometric ratios of room volume and separating area (V/S). If a permissible deviation between R'w and DnT,w is accepted, a classification of the sound insulation values (R'w) with fixed class limits can be made. This makes it possible to classify the sound insulation with reference to the descriptive parameter DnT,w using the weighted apparent sound reduction index R'w. [ABSTRACT FROM AUTHOR]
