My guess is winds effect volume level in different parts of the stadium somewhat. I could hear the PA just fine this game and the volume wasn't painfully ear damaging loud this time. I think not destroying anyone's hearing, or clipping the amp should be the priority in volume level. Sorry if it isn't quite as loud in certain places, but a stadium is not an ideal place for sound especially with a permanent system of questionable quality and age. Really doesn't bother me except when it is dangerously loud. The music selection and constant need to fill space do bother me though.
