I live in a residential area myself .. and, periodically, I'll have an outdoor party where I set up some gear and 10 PM is when the noise ordinance kicks in .. up until then, it's pretty much anything goes .. even at low output, a proper system will rumble and sound will carry, it's the nature of the beast ..
Now, if your contract specifically contains some sort of noise definition, (which is pretty hard to define definitively) ..
Point being, there is no need for me to haul 800 pounds of equipment if a transistor radio has to suffice ..

.. in addition, this morning I have toyed with bringing a Karaoke player and disks as well, which just adds to it ..
So, I'm making it clear that if I bring the gear, things gonna get loud, at least pre-10:00 PM .. sound travels, it cannot be contained .. as well, I personally could care less about the neighbors since I meant it when I said it's not a Party till 5-0 gets called .. Hell, invite the neighbors for all I care ..
