Staggered partition
As everyone knows, sound passes through the air, in the form of vibrations.
On the entire periphery of the frame, glue a resilient foam (floor, ceiling, wall).
The finished partition must be completely caulked around its entire periphery.
To improve acoustics, separate the room with two partitions. See diagram below.
BENEFITS
For new or old sites.
High performance (phonic).
Elimination of the risk of cracking.
Adhesive foam tape for acoustics and waterproofing, is used for acoustic, thermal insulation and airtightness of partitions on metal frames (top and bottom rails and side uprights), allows to limit the propagate sound waves and dampen vibrations.
Two layers of GR 60 mm glass wool
The two partitions do not touch. To gain thickness, the uprights are staggered. In this diagram, there are two crossed skins. The plates, whether there are 1 or 2 skins, must always be crossed for rigidity and sound.

Dubbing
Partition-lining connection
The dividing partitions between apartments must systematically be connected to the shell.
The dubbing, whatever its nature, comes into abutment against the partition.
Wood partition-floor connection
The floors must either be cut in line with the partitions or lined with a screed in at least one of the premises concerned.
