resilient bars / sound proofing

[bigdrew]

Renovating a semi house and wondering about attaching these to the party wall. Currently get a bit of TV noise through but nothing drastic.

Not expecting silence and probably impossible to achieve as the joists run into the divide but it would be a fairly small outlay at the moment.

Anyone used them or have any comments?

I'd be looking at attaching them directly to the existing plaster / brick with two layers of sound board plasterboard attached - Not willing to sacrifice the extra 50mm for batons..

Also considered green glue but looks fairly costly!

Resilient bar... 19mm plasterboard, then 12.5mm plaster board. Should be decent level of soundproofing without loosing a lot more room space.

That's what I had in my mind and for fairly little cost. Most methods involve 50mm batons on the wall and rock wool in between and then the resilient bars but but that's a fair bit more off the room!

IIRC Builder Depot was cheapest for 19mm PB when I did my studio last year.

We rented our house for several years and the tenant, a carpenter, added false walls and soundproofing to three of the adjoining walls, as the partition was made of what seemed to be tissue paper! Before we rented it out we could hear simple loud conversation through it, and baby crying at 2am.....

However, even though that noise has gone it still sounds like a herd of elephants are running round, when the kids come home from school. I guess the noise simply follows through on the floor joists, and our floors act like giant loudspeakers. Heavy carpet might be an answer?

The resilient bars are more to prevent impact on your face resonating through. If you're tight on budget and space the plasterboard layers will have much the same effect in a wall, resilient bars are more use in party floors.

I don't get impact noises as such. Its an old lady next door who has her TV on a bit loud. Maybe the layers of plasterboard dot and dabbed straight onto the wall will be suitable then?

To future proof it would be nice to cut impact noises out but I think it will be impossible with the house design. (Joists resting on party wall)

My economy ceiling effort is nearly complete, built using:

Battens - http://www.diy.com/departments/cls-timber-38mm-63m...
Leftover standard 100mm insulation
Resilient bars - https://www.randjbuildershardware.co.uk/buy/resili...
2 x 12.5mm plasterboard layers - http://www.diy.com/departments/gyproc-tapered-edge...
Self-drilling screws - http://www.diy.com/departments/avf-zinc-effect-ste...

All B&Q stuff self-delivered for £15 - http://www.diy.com/hertz247/

Also have some sealant, possibly acoustic specific but as far as I could tell value for money drops off cliff when the 'acoustic' label is applied to a product. Total depth ~7.5cm.
