I'm sceptical how much this will help, but want to help out a family member with as small project, just want to make sure I make it as good as I can for the outlay in time and materials.

Single wall to be done in a bedroom, party wall is brick and at a guess reasonably thick, not single brick, 70's 2 bed semi. 3m*4m in size.

Current plan is to run horizontal battens 40mm*40mm on the wall, and fill the gap with mineral insulation and then double plasterboard on top of that, using resilient bar to hang the plasterboard.

Would constructing the frame so it is attached to the ceiling and floor only (no contact with party wall) be that much better? I can screw down into the floor, but not sure how strong the ceiling fixing will be. Would rather avoid having to investigate.

Would having vertical wooden battens and horizontal resilient bar be stronger? Or is there nothing in it?

Anyone done something similar?
 
Ceiling and floor vertical will be better. Separate the stud work from the brick wall.

You could also go for acoustic plasterboard, depends on what sort of noise you're trying to mask. (you will also need to do something for the wall under the floorboards assuming its not concrete?
 
More like this then: ( I won't use mat $$$)

there is no carpet down currently so the floor fixings are easy, can find the joists, and the chipboard floor will take a decent fixing. But into the ceiling? I think it'd be harder to find the joists. And require twice the timber, would the results be that much better?
I plan on using a strip of EPDM rubber along the resilient bar behind the plasterboard too.

It'll be acoustic plasterboard but the cheaper end stuff not super fancy double skin rubber inside type.
 
it's a good way to do it but the end of the floors are as likely to be transferring the sound over so it might not make a lot of difference if the sound is coming through the structure

This is exactly what I've just done in my bedroom. There was an awful fireplace with really bad brickwork that was exposed when I pulled out the ancient built in wardrobe. I figured it was easier just to hide it and better to just have a flat wall so built a stud wall across in front, filled the gap with celotex then used soundbloc plasterboard.

Just put noggins in between the joists in the ceiling and screw the head plate into those.

Also meant I had space to run a load of Cat6 down the back! :D

It'll be very hard to get into the ceiling to get noggins in, finding the joists below would be an option however. Did you secure your end uprights to the wall or not.

But maybe you've not built it from a purely sound reducing point of view, just an additional easy flat wall to the room. I read a guide on it the other day and cam't remember if it said to attach the end verticals to the wall or not, or just have it floating and secured top+bottom only. Time to go googling again.
 
Ah damn, I had quite easy access to the loft space above. I screwed the end plates to the wall too. I built it mainly to flatten the wall, sound proofing was a secondary bonus. To be fair it does seem to do the job very well. I can hear the neighbours occasionally in the adjacent bedroom with a party wall but I don't think I've heard them at all in this room!
