[Where do you draw the line with noise in your area.]
I draw the line with my own personal responsibility.
I am in a rock band so there is a potential to disturb others. Our solution is to never play in residential areas or any place where people could reasonably be bothered by amplified music being produced in the vicinity.
We rehearse in a basement studio but we completely soundproofed the room so that we could even play at 2am and not a peep of noise can be heard outside the house (our volume level is 106 dB inside).
Just proves you are a human being. The morons down the street play in their parents garage with the door open. The parents seem to not care or notice. Shit people breed shit children.
