When I held my test sessions (am now retired), I have signs on the doors reminding every one to be quiet. The few night sessions I've had, you'd always have to shoo some ding-a-ling kids out of there - same in the summer when the hockey camps are going on.
Sometimes, there is the senior long blades going on next door. Some of them are pretty hard of hearing and the old-fashioned organ music gets turned up pretty loud.
