Is regional sound a little loud for some outsiders to come in? In some cases yes, some people don't like the loud noise, but I don't think is is something to fight over. Have you ever sat in the stand on practice day? I don't know about other regionals, but at GSR is is wicked lame as they have quiet music and no emcee. It is not the same without the loud music.
Personally, I find off-season competitions worse as they are held in gyms which echo a lot more that the average multi use arena. Echo+loud music= bad day as you can't hear the music, those around you, the emcee, or your brain hurt!
