So I've lived in my semi detached house for just under 2 years; friends with the houses across the road and to my right, but my actual direct neighbours (an older-ish couple) have always avoided eye contact and ignored my 'hellos'
We don't really hear much from them, apart from their little dogs incessantly barking and very occasionally they BLAST their music (though more through poor hearing than trying to be anti-social I think?!).
Anyway, to my surprise, before the weekend, the lady came round and said that for the past few months there's been a deafening vibrating/machinery sound coming from my house that 'shakes the wall' and causes their dogs to fuss. I was shocked and completely clueless as to what could be the issue as I work from home in a little room at the opposite side of the house and the most noise is our tele on an evening.
Our adjoining wall on my side is a long living room/dining room and upstairs master and spare bedroom. The only electrical items plugged in at all are the TV (and currently Christmas tree), neither of which emit any noise whatsoever. There's no plumbing, radiators or anything else that's powered plugged in on that side.
She said sometimes it was so loud they had to turn the tele up and she'd heard it after 1am the night prior. I explained there's nothing electrical along that side of the house and that the only thing plugged in was the tele. I also told her at 1am, we'd have been in bed for hours ha! I said she'd just have to let me know next time she heard it and I'd investigate with her.
I panicked it might be our wood burner or attached fan however it couldn't be at that time and we hadn't even had a fire on the occasions she'd mentioned.
I ended up having a slight run in with them today, on a blasting music occasion as I was working from home and couldn't hear myself think. She brought it up again and said her son had visited the previous evening (who cares about lock down eh!) and had mentioned it too. I asked why she hadn't come and said something as I couldn't help her if I didn't understand. She said she would this weekend...
What the heck could it be?! And is it my responsibility to sort it out?! Neither me or my partner have noticed any noise of that sort (she likened it to an engine speeding up, or a sewing machine) and I'd consider us good neighbours as we're considerate and quiet, but she's convinced it's our problem!?
Gaaah!
