Good luck nyc in finding solutions. I live a reasonably quiet building. I don't mind noise upstairs (current residents above and around me are quiet) above me, as long it's not at night when I'm trying to sleep and not someone being violent with another person.

I grew up in a large family and as the oldest did remember some nights of baby sibling(s, depending at what point in life) crying and during the day, children running around while I was studying or resting.

A while ago, I lived in a building where the last 3 months before I moved (because I sold my place), someone upstairs seemed to be running some sort of exercise machine... I ended up sleeping in my living room during that time.
