DIN EN 1793-6:2013-04

This European Standard describes a test method for measuring a quantity representative of the intrinsic characteristics of airborne sound insulation for noise reducing devices: the sound insulation index. This quantity should not be confused with the sound reduction index used in building acoustics, sometimes also called transmission loss. Research studies suggest that a very good correlation exists between data measured according to EN 1793-2 and data measured according to the method described in this document. This method may be used to qualify noise reducing devices for other applications, for instance, to be installed along railways or nearby industrial sites. In this case, the single-number ratings should be calculated using an appropriate spectrum. The Working Committee responsible for the German collaboration at DIN is NA 005-10-26 AA "Lärmschutzeinrichtungen" ("Noise reducing devices") of the Building and Civil Engineering Standards Committee (NABau), acting as mirror committee of CEN/TC 226 WG 6.
