wont be that loud, but i don't think they can just walk into your house?
with suspicion they can enter your house
as in if they look into the window and see a beer can
or kids being trashed outside your house
or anything of that nature
also, remember that neighbors are not your friends; they are your enemies. they'll be the ones calling the cops.
best advice I can give you:
control the music
close all the windows, blinds, shades, and curtains
have everyone use Solo Cups
don't let anyone hang out outside the house/gate/whatever
have the party in the basement if room will allow
