We can all agree that arenas are loud as **** during the playoffs so that's a different argument. I've attended games in less-traditional arenas but the ones I've been to are Nashville (obviously), LA, Anaheim, Florida, Colorado and St. Louis. I've gotten multiple sample sizes in Nashville, Florida, LA and Anaheim.
-Game in and game out, Nashville tends to be pretty loud and active even if the game itself isn't really a big one. The loudest game I've been to this season (I've been to all of them) was a random Tuesday OT win against the Kings. Not any kind of rivalry game but the place was jumpin. Much like Winnipeg, the noise is boosted from having a small arena. Given the location of the Preds arena you'll get a lot of people that use a game as a place to drink for 3 hours and be loud before going to all the honky tonk bars right outside later that night. It's an interesting place.
-One would think that St. Louis is pretty loud (and I'm sure it can be) but the game I went to the Preds won like 5-1 so that's not a fair sample.
-LA is usually pretty good but the arena is so open that it's hard for it to always be loud. They got a lot of **** for having bandwagon fans but there's a pretty decent amount of big Kings fans there, I'll say that.
-Colorado was okay. The Preds won the game 6-1 and they were having a bad season so a random Tuesday game against Nashville wasn't going to be a huge draw. I'm going to the Preds game there on Friday and I'll be curious to see how it is this time around. Plus Rinne is out so they'll probably have a lot to cheer for.
-Anaheim was generally pretty weak in my experiences. I did to a playoff game there (the Ducks won) and I thought the playoff crowd in Nashville was much louder by comparison and it wasn't even close.
-I spent a season going to Panthers games and the loudest it got was when Montreal scored goals there.
So much of the perception of what buildings are or aren't loud on TV can have a lot of different factors. When I think of loud buildings I've seen on TV I think of Winnipeg, Montreal, San Jose, Nashville, NYI (this season), Philly and Calgary.....for some reason I've always thought of them as a loud building but I don't know if this is true.
