I seriously don't understand why this is an issue. I know so many sports fans that attend games and have never once been to a game with or heard from a fan that enjoys or even tolerates the noise level at Calgary sports events at the Dome these days.
It's 100% "Holy crap, I could barely hear the people I was with and was bothered by the volume all game". Maybe it's my crowd, but I've never met a single person that enjoys the Saddledome noise levels, I honestly don't know where they're getting their fan metrics from when it comes to the continuation of this?
