Been through this one before. Im in 100% agreement with this and a PA should be hearable. not domineering. I can't even say a word to the person next to me when the PA is blaring.

Even if I think the announcer is top notch and does a great job announcing lineups. It can be just too much and TOO LOUD. Have someone walk out of the booth, go sit near the speakers for five minutes and come back. I bet they say. Dude, cut back a couple notches.
