First of all, think of common decency here. 10-11pm at night with 9 people is absurd, especially in an apartment complex.
According the Hartford CT law, they have instituted a noice ordinance. Read it, learn it, and be more respectful towards your neighbors.
If the police continuously get called out to your specific apartment at those hours, you can expect a court date.
