Gypsum blocks as partition walls

The airborne sound insulation between two adjacent rooms in compact construction is determined above all by the surface related mass of the separating wall. 

single-leaf walls made from gypsum blocks, already with mean gross density, achieve a rated sound insulation mass Rw,P of up to 40 dB with 100 mm wall thickness; with higher gross density and the same thickness it is 44 dB

For double-leaf walls values up to 68 dB have been determined whereby the proposals for an increased acoustic insulation in accordance with Supplement 2 to DIN 4109 can certainly be achieved.

The values given apply for undisturbed walls without doors, channels or other openings. With walls with openings as a rule the doors are the weakest link whereby the quality determines the acoustic insulation of the complete wall.
