The way it's going is that our next-door neighbours keep putting on inappropriately loud music at annoying times of day. Like 4 o'clock in the afternoon or 10 at night. This is particularly selfish, as they have neighbours on both sides. Also, they have (imo) appalling taste in music - most of what they play is the stuff that's currently called "R&B". So I can have coming through my wall just the same 3 or 4 notes repeated over and over as the bass throbs through.
So I put on our stereo instead, usually with something fairly obnoxious. Like Paradise Lost (doom goth metal/synth crossover), Punk covers of Pop songs (Britney Spears & Backstreet Boys done punk-style), or Richard Cheese (lounge & big-band covers of rock, metal and rap songs). Not extremely loud like theirs, just loud enough to say "hey, if you can hear my stereo, then I can hear yours". Generally speaking, within 5 minutes of me doing this, their stereo gets turned down to a sensible volume. Result.
It's obviously not a very good result, though, because I have to keep doing it. Now, I quite like music, especially when I'm doing housework. so it's no skin off my nose. Plus we have no neighbours on the other side, so no one's being inconvenienced except the offenders. But I'm wondering what the best thing to do long-term would be, as they're just Not Getting the hint.
Write a letter to the neighbours? (made awkward by the fact I have no idea what their names are or how long they're going to be living there). Write to the letting agents? Write to the local papers? Or the council noise-prevention people? Or all of the above? Note that I really am not up to going next door and reasoning rationally at the moment - my nerves are all frayed by being ill.
