Sound proof stud wall suggestions

JuzaMum

Hi.
I am splitting a room to make a bedroom and separate shower room (not en-suite). What is the best way to construct/insulate the stud wall to minimise the sound travelling through the wall?
Thanks

Double board each side with overlapped joints.Obviously filling in with insulation after boarding one side.This,I believe, also gives you and extrahour fire break. There are however,various type of boards available that are used specifically for soundproofing. Ask you local builders merchant.

The blue plasterboard is denser and is sold as soundproofing. If you are going to double board then I'd do the blue first and inside the bathroom green board (moisture resistant) on top and the normal board on top in the bedroom.

You can also use resilient bars on the wall which means there is less contact between the stud work and plasterboard reducing vibrations through the wall.

An Acoustic Insulation Slab fitted in the wall between the studs should provide thermal, acoustic and fire insulation, it's relatively cheap and easy to fit.

I did my partitions with 15mm Soundbloc plasterboard each side and ordinary sound quilt inside. They are good enough. Bear in mind all gaps and joints should be meticulously sealed - joints, floors, ceilings. Then remember a typical modern door will be useless for sound transmission relative to the partition, so the sound will transmit through here.

Common sound proofing type doors are available, so search these out - like developers doors at Howdens, or Premdor/Masonite hardboard embossed sound proof doors.

Thanks all for the replies. Fortunately I don't need to worry about a door as from rooms will be accessed from a corridor.
