I'm actually on the other end of this problem at the moment.
There's an old guy living above me who constantly complains about the noise I make, not to me but to the council. When I first moved in he came round and complained and I turned it down for him and offered him my mobile so if it's ever too loud just call and hang up and eventually I'd be able to get an idea of when and how loud I can get away with it. He refused and skulked off. I haven't switched my sub on since and I'm in bed by midnight most nights yet he now complains direct to the council. He's even complaining when my flatmate has the TV on in the front room after midnight (she works in a bar so is always up quite late) despite the fact I can't hear it in the adjoining room. It's ridiculous. I can't cough in my own house without him filing a complaint.
