We have very quiet neighbours.... it's their wall mounted telly that's the problem .( no idea what make it is.) Mentioned the problem to them, dull low vibrations thru the wall where the fire places are. They have turned it down a little but it's so annoying we are thinking of moving house! Is there anything else we can politely suggest to them to stop the vibration. We have already soundpfed our wall and the back of our fireplace but with no effect whatsoever. It's such a shame that whoever decided it was a great idea to wall mount tellys did'nt think about the effect it has on neighbours!? HELP!
