In my experience that never, ever, works.
You know, live and let live really helps as a philosophy.
Unless neighbor aims to annoy, it could certainly help to have a talk. I have a neighbor (property next to mine is a smallish apartment building) who used to have TV on all hours, yes even 3-4AM, loud enough to drive me up the wall. I tried various kinds of ear plugs, used to buy them by the box. That helped, but it sucks, is only partially effective and the most effective (gummy things you pinch into shape) waxed up my ears.
I talked to them one day, knocked on their door, had a peak at their sparse furnishings, got a perception of the woman who lived there, at the time with her two sons, apparently. I voiced my concern and she goes "is it too loud?" I didn't answer, what a stupid thing to say. Why would I be knocking on her door if it weren't??? This must be over 10 years ago now.
I would rack my brain, trying to think of some way I can get it to stop. I used to go out in my yard and shine a flashlight on their window back and forth, as a signal that I was here and annoyed. One day/night I tossed a firecracker in the courtyard between us, a simple small firecracker. I observed the woman look out her window for a moment.
One night, maybe 1AM their TV was on so loud I could make out the broadcast's English. I figured it was time to call the police and I did. I don't know what came of that, if the cops came, just don't know, but somehow I have the impression that the perps were alerted. Things gradually got better and now it's rare that I hear stuff from them. It does happen, but when it does it's loud music but not during sleep time... usually, and it does not persist. I just think that them knowing that I was annoyed with their noisy trip influenced them, even unconsciously to consider that their lifestyle was problematical. I mean, having your TV on all the time isn't good for your mental health. I figure it's done a lot in the USA, that is to say, it's not unheard of. Many watch TV for 6 hours a day, in fact I think I heard that was average or something...
I had a roommate here in this house when I was sharing it with other people who made it a point to annoy. He actually left his hifi or TV on with the volume up, locked his door, left the house! He did some petty vandalism here too, a real case. He was the "friend" of one of the guys who lived here. He didn't last long.
