If the landlord doesn’t help, noise complaints exist for a reason. Check your city’s noise ordinance. Most have quiet hours (typically 10 PM to 7 AM). If they violate those, you can call the non-emergency police line. Yes, it feels extreme, but constant noise is a health issue—it raises cortisol and makes you a grumpy potato.

Before you call, confirm it’s a pattern. One loud party? Annoying. Three loud parties in a week? That’s a violation. And remember: you’re not being a Karen. You’re protecting your sanity in a shared space.
One warning: calling the cops can escalate tensions. If you’re in a rental, this is a last resort. But sometimes, you need the threat of a fine to make someone care. (Side comment: I once read a story about a man who played bagpipes back at his noisy neighbor. Do not do this. It only leads to more bagpipes.)
