IF the school is positioned so sound generated there would travel quickly to a lot of residential sites, wanting to be a good neighbor, outdoor speakers might have to "Go".
My Ravens Grin is in a small valley and such sounds travel very quickly and unimpeaded right to the houses on the hill.
This small village of elderly people like "Quiet" and I like to get along with everyone so I had no trouble disconnecting my October outdoor speakers here. As I face that hill half of it is grave yard so the UFOs that land there run on very quiet mode.
Then on a Sunday afternoon Harleys come to town and you can hear them from 2 miles away!?? WTF?
