Huh, it's interesting reading about the US college system. Never really occurred to me about the underage drinking that must go on.
To me, OP certainly had the right to call, but knocking on the door and asking for some quiet would have been the better option
For comparison, this is how it goes at my uni (Australia)
8:30pm all nights - has to be quiet enough to study
10:30pm all nights - has to be quiet enough to sleep
Subwoofers are banned, and will be taken & donated to charity if discovered
In my block, alcohol can only been consumed in our rooms, in all the other blocks it is banned in rooms and can only be consumed in common rooms.
Our 'RA' s are actually a group of people employed to look after us, not students.
They have the right to enter the rooms of every other block without the owners permission, but for my block they have to have permission before entering.
Total noise ban/alcohol in common area via during study and exam periods
My neighbours above me can get a bit rowdy but they're pretty good natured, if I let them know I need to sleep they keep it down. The RAs have given them a few warnings by the sounds but nothing serious.
