Hi, I am seeking advice on a project that I have started concerning an upstairs bedroom. The neighbouring tenant is clearly heard daily and more so in the early hours, you can hear coughing and bed creaking amongst other things. In addition this neighbour is non-communicative/troublesome. Anyway my Local authorities' Environmental Health dept. states that my only option is to Soundproof as the nuisance is classed as acceptable 'living' noises. Never the less it's like the neighbour is inside your own home and very irritating. So I determined that the noise is emanating prominently from an alcove wall between an upstairs bedroom's chimney breast. I have misguidedly purchased 15mm knauf soundshield plasterboard and put it up from floor to ceiling with plasterboard adhesive also put filler in any gaps to make it all a solid airtight structure. However this has made absolutely no difference in reducing the sound coming through. So I am debating about what to do next... All advice welcome but I do not intend to remove what work that I have already finished so hopefully someone out there has an idea on what to add to my project in progress.
I have a similar issue and I applied the same soundproof boards without any change whatsoever! I've been told the only way to fix this is to have a stud wall fitted with sound proof bars/insulation etc or something along those lines!
I also think the sound travels through the wooden beams and as they interconnect it's almost impossible to repair this issue!?
