Gypsum blocks as adjacent walls 

The acoustic insulation of a partition wall actually realised, in addition to its own surface-related mass, depends also on the type and bonding of all adjacent building units. Through the elastic connection of gypsum blocks the flank transmission to adjacent building units is considerably reduced.  

Flankierende Wände

1. MultiGips Gypsum block, 60 x 500 x 666 mm

Or put in another way: as opposed to rigidly integrated adjacent building units, partition walls do not or only slightly stimulate themselves or adjacent building units acoustically when elastically connected together.
