I'm a sufferer too. Had it for years and can pin point the first time I heard it - drilling a whole in the wall. I stopped and thought I'd hit a gas pipe, got the kids out quick but could still hear it outside.
It's got worse as my hearing has deteriorated and I find the best thing is to try and ignore it. Red wine tends to make it worse but I can live with that occasionally.
It's annoying, it's infuriating but it ain't gonna kill me
Good luck with your management of it.
