DIN EN ISO 140-16:2006 声学.建筑物和建筑物构件的隔音测量.第16部分:通过附加衬套对噪音减少索引改进的实验室测量(ISO 140-16:2006)
Acoustics - Measurement of sound insulation in buildings and of building elements - Part 16: Laboratory measurement of the sound reduction index improvement by additional lining (ISO 140-16:2006); German version EN ISO 140-16:2006
This part of ISO 140, as a complement to ISO 140-3, specifies the laboratory measurement of the improvement of the sound-reduction index of a wall or ceiling when covered by an additional acoustical lining. It also provides for individual non-standardized basic elements. This part of ISO 140 does not deal with the sound-reduction improvement by linings on flexible lightweight structures, such as timber-frame floors or double-leaf gypsum board walls.
