DIN 4109:1989-11 DIN 4109 Bbl1/A1:2003-09 Sound insulation in buildings, examples and calculation meth-ods correction A1.For verification of sound insulation according to DIN 4109, Annex 1 : A1:2003-09, table 40 the weighted sound reduction index Rw corresponds to the test value Rw,P, GLASRw,P, GLAS = 44 dB4.2Laminated glassThe sound reduction of laminated glass depends on the temperature of the environment. If the temperature is lower than the test temperature the sound reduction index may be re- duced.4.3Test standardsThe standard series EN ISO 10140:2010 supersedes those, until the respective date, appli- cable parts of the standards series EN ISO 140 which describe laboratory tests. According to the two standard series, the test methods are identical.ift Rosenheim Centre for Acoustics 01.
