excessive noise

I am curious whether fraternities/sororities
have their own standards/rules about excessive noise.

I have been living next to a Delta Psi
(St. Anthony) fraternity for three years.
Previous to this summer, these people would
have loud all-night parties occasionally.
Boys will be boys, we can live with that.
However, this summer, there is a party on the
roof every night with loud music and yelling
until all hours. I have to work each day,
and cannot tolerate having my sleep disturbed to this extent.

What do you suggest? Do the neighbors have
any recourse? Aren't you all supposed to be
trying to become upstanding members of the
community?
