I had an issue with a restaurant I live by. They always play loud music outside which I was okay living with, but one night they hosted an outdoor party on the street with a DJ and had music blasting until 11pm on a Tuesday night. That night I called, talked to the manager that was working on the phone to try to work it out amicably and was told to "Fuck off" so I took revenge and it was really easy.

Instead of going through the city which is useless, go through the Pennsylvania Liquor Control Board. I submitted the contact form and called the number on the website, and got a call back from a police officer a day later and talked to him for a while and he took care of it. Never heard another peep from the restaurant. I'd recommend documenting everything with pictures, videos, and timestamps and then let the PLCB do their jobs as they take it a lot more seriously than the noise ordinance department in the city government.
