What is the policy that you guys use regarding closed ear audio devices...such as in-ear heaphones, or just headphones in general. I try to discourage the use of such devices when using power tools, specifically any saws, but we don't have any specific policy or rule about it. It is generally accepted that no personal audio devices are used on stage, because there is so much happening. I was just wondering how everybody feels about this, and if anybody else has defined rules regarding it. ps: there is one rule that we follow at all times in the shop, NO SHOWTUNES.
