Generally don't care about a little noise, or random noise that happens maybe 1-2 times a day, but repetitive and continuous noise, even if it is intermittent is disturbing. At my parents house we had immigrants from far away that kept screaming, dragging furniture around and talking loudly from 01:00 to 04:00 at times and it was impossible to visit my parents and sleepover during the last few years. I finally recorded them (as in a microphone just laying on the floor - i didn't exactly need CIA surveillance stuff - they were just so damn loud!) and i posted it on youtube (hidden link) and sent the link to the landlord.
If one listened closely to the recording, one could hear men talking loudly (don't know the language) then a woman coming in and criticizing them, then some shouting from the men followed by a woman crying... not hard to guess what happened there. The problem was centred around one idiot i identified which obviously had some mental issue and denied everything, called me and my sister racist, came with threats (obvious Hare-type), a few months later the men did not visit the apartment except on occasion, they obviously had been evicted by someone. A neighbour in a nearby highrise could see that the "man" in question was beating their little children. After that was reported they put up thick curtains so it was impossible to see what was going on. The first time we reported them, all men ran away and an little CHILD stood in the door had to defend the family when the guards came along to investigate the disturbance.
Last December (2017) every one of them packed up their s**t and moved away. I can finally visit my mother again and sleep in the living room for a full night - 6 years of hell.
I did fight back during the last time. Basically if they made any sound, i made sure the could not sleep from 07:00 to 11:00, which was their normal sleeping time during weekends. Pretty sure they did drugs, because they were paranoid as well.
Earlier in the same apartment, a local Swedish family lived there, same kind of s**t. Late night parties, moving furniture, and bouncing basketballs during the night. They also had to move, but they couldn't use the word "racist" so it was easier to make them go away. One guard that came by to investigate a disturbance told me that "even i in my profession has been called a racist, and i'm from Iraq."
