I need some advice on soundproofing my bedroom as the noise from the TV next door prevents sleep. I've been round to their house and the offending TV is downstairs against my living room wall. I had that wall soundproofed and it has worked a treat but I couldn't do the same job upstairs due to space and cost. Downstairs I had a timber frame built which was about an inch off the offending wall and was filled with acoustic rockwool. Acoustic boards were then fitted and skimmed over the top. Upstairs, I just had acoustic boards stuck to the wall and skimmed over. I can hear their TV clear as a bell up there and I think the sound must be traveling through the floor cavity or the small gap between the boards and the wall.

Asking them to turn the telly down has been tried as has the council noise abatement team, to no avail.

I'm at a loss with how to soundproof this room apart from lifting floorboards which would cause a lot of damage, both to the floor and the soundboards sitting on top

Any advice appreciated
