I live in a block of flats where our door and our neighbours' door open onto a shared staircase and there's about a metre of space between them. The doors aren't terribly soundproof since they're normal interior doors, not exterior ones. I then have a tiny vestibule and another door between that and my main room.
Neighbour plays some kind of computer game something like 8-10 hours of the day. At the moment he's been playing for an hour or so and it's so loud I can hear it clearly when I'm sitting as far away as I can be. It's not appallingly loud, it's just tedious having constant background noise.
WIBU to ask him to turn it down? I've done this previously when he decided to start sweeping up the mess his builders had made on the communal steps and left his door open so he could hear his TV while he worked, and he was fairly angry, but did do it. DH tends to reckon this is part of living in a flat, but it's getting me down.
