The DIN 4109 series of standards has been revised in recent years and harmonised with European design codes. After the drafts of DIN 4109 were issued in November 2013, the documents shall now be finally published in summer 2016. The calculation procedure according to DIN 4109-2 is based on the simplified procedure from EN 12354:2000, in which the noise transmission routes are calculated individually, similarly to the calculation for framed buildings according to supplement 1 to DIN 4109. The procedure according to DIN 4109-2 is based on formulae, which are filled with figures from the building element catalogue of parts 3-2 to 3-6. This article shows examples of calculation steps for the determination of the weighted airborne sound reduction R'w,Raccording to DIN 4109-2:2016 for a floor slab between residential units.
