Eh, depends on where I am. At a hotel, probably not until things seemed to be moving into threats. In your situation, I would have called the desk first after a few minutes of sustained noise, and only gone for cops if that failed.
At home, I know most of the neighbors well enough to be able to tell > what’s going on and why, so I’m slower to call when I’m sure nothing is going to happen. If it’s someone not from the neighborhood, or is unfamiliar, I’ll call when things get loud enough to hear it over fans and such. Then again, I know the local cops too, so I’m confident in their unwillingness to jump to violence themselves. Smallish town, smallish department, and the people in charge aren’t batshit about the whole “warrior” bullshit.
When I’m pet sitting for a friend over in the city, idgaf, I’ll call as soon as it gets loud enough to notice, and doesn’t stop in a minute or so. Don’t know the people, don’t know the cops, but I’ve got an obligation to my friends to keep things as safe as possible.
But yeah, if there’s a kid involved, you call sooner rather than later, same once things start getting broken.
