The document specifies a method of determining the design value as specified in DIN 4109, clause 6.4.1, of components whose weighted sound reduction index Rw was measured in accordance with DIN EN 20140-3 or DIN 52210-1 (in test stands without flanking transmission). The conversion method applies only to single-number ratings for Rw determined in accordance with DIN EN 20717-1 on the basis of the one-third octave band values of the sound reduction index R obtained on test stands in accordance with DIN EN ISO 140-1 or DIN 52210-2.
