I'm planning to build something like this...
http://www.soundproofingcompany.com/..._construction/

....with 4x2 top+bottom, and 3x2 studs.

Has anyone every successfully put a corner into one of these without
joining the two sides together (which would make the whole thing
pointless)? If so, how?!

Also, Noggins.I've seen suggestions to put little 45 degree pieces top
and bottom internally, since conventional noggins would simply couple
the two walls together (making it pointless). Any other ideas?

You can build them further apart, like this:
http://www.diydata.com/general_build...tion_proof.php
....leaving room for conventional noggins without bridging the two
sides, but I don't want to "waste" that much space.

Shall I try to fit sound insulation into the little 1" gap behind each
stud, or just put it in the larger gaps between studs?

Cheers,
David.

Corners are relatievly rigid, so dont much compromise sound
resistance.

you could upsize from 2x3 to 2x4 uprights at the cost of another inch
of space, but I dont know how much sound insulation youre looking for.

2 layers of 12mm PB on each side helps too. If not enough space for
that you can always stick scrap PB or even plaster to the inner side
of one of the PB where the gaps between studs are to stiffen and
weight it.

You can also add weights to the uprights to redce movement. Its less
easy with no noggings, but still doable.

You can set conventional noggins on their side, so using 50*100mm
studs you would need to be only a shade over 150mm wide top and sole
plates.

Everything counts, so thicker studs (particularly with higher
ceilings) give extra stiffness, as does adding extra rows of noggins.

Thicker plasterboard, sound deadening plasterboard (e.g. LaFarge dB
check) double staggered layers, denser sound insulation material,
peripheral airtight seals around the wall, more screws, carefully
positioned sockets - all counts - as does just good workmanship.

Check out Part E of the approved docs for lots of proven good advice.
