Is there a policy for the use of music and sound effects during RPG events?

I've played in events where the GM had sound bites that lasted a few seconds, which seemed okay. But I have also been in RPG rooms where GMs are playing music and sounds for at least a few minutes. The latest situation got to the point where the offending GM even turning it up when others in the room asked to turn it down.

Our GM didn't know if there was any sort of recourse for this.

The policy is to be mindful and respectful of those around you. 

In this situation, please find a Hall Captain or the closest Captain (In a Black Vest) to help arbitrate the situation.
