We're experiencing noise problems from our neighbours, and are looking at soundproofing the party wall, so we're after any advice/tips/help.
We're in a 1920's 9'' brick semi-detached bungalow, concrete floors, roof-space mainly seperate (there is a small gap in apex in one part). The main source of the noise is the neighbours TV, and most of the noise that we get seems to come through the walls rather than floor or ceiling. The people in the house before us had dry-lined sections of the walls (interestingly, mainly where the noise is worst - if only we'd spotted this when viewing!). The stuff they used is plasterboard backed with a couple of inches of blue foam. As far as I can tell this is attached to timber battens, which are in turn attached to the brick work (which I suspect is not rendered, at least in places), I don't think there is anything else in the cavity. I've got a feeling this may actually be amplifying the noise.
We have been looking at the products available from specialists, which seem very expensive (but then what cost do you put on peaceful sleep?!). From looking at posts here it seems there are plenty of people doing their own thing. Can anyone help?
Thanks a lot,
