Electrical boxes on accoustic stud walls

[sparkwright]

Wall is a party wall, metal framework, 2 layers of 15mm fireproof plasterboard either side. Still under construction.

Will fitting wooden noggins with metal electrical boxes compromise the sound proofness?

Boxes will have all holes and gaps sealed.

Ordinary sockets will compromise acoustic performance. You can get acoustic boxes which need to be fitted to the back of the plasterboard layer with acoustic sealant. These must be fitted before the board is fixed.

It will also compromise the fire resistance of the wall
