Ahahah, wow, not a hockey fan but that sounds pretty dang hype. I tend to be a fan of mid-to-high scoring games because I like more "action" in mine but I can kinda see the appeal in sports like soccer and hockey where teams rarely get into double-digit scores AFAIK.
That loudness sounds insane too, I have sensitive ears so I'd have probably been in serious pain and/or just like... passed out or something lol, can't even hear yourself shout? oh man. can hardly even imagine it.
The nature of hockey is a pretty weird thing. It's physical and fluid...a combination that I only recognize in hockey, lacrosse, and rugby.
Of course, low scoring =/= low action. It's certainly not like association football in the sense that there's a lot of recoil and set up. Actually, the other side might be fair in the sense that physical play is absolutely part of the game. You can derive fun from watching "physical" teams (teams which utilize size to leverage physics in their favour when bumping into one another) or skilled ones. I know basketball uses the idea of a "power forward", one which uses size more than skill offensively. Hockey's equivalent is also known as a power forward...difference being quite a few hockey power forwards have the ability to knock people over too. A player by the name of Michael Ferland basically makes a career out of being a hard hitting power forward and there was a point in time in the playoffs last year where he basically make an entire team fear him. Apparently you can make a 15 minute video out of him running into people. And all of it's crazy amounts of action.
Of course too though that some teams just play boring. I'm sure that happens in all sports though. Heck, I'm sure even "high scoring" games like gridiron football and basketball have their share of teams which decide to play the most boring yet most controlled style of play in existence so that they can sneak out victories they might not get from a run and gun game (ex - winning purely via field goals and short runs in gridiron football. It's not flashy but you can control play better and get points more easily). Any team like that can get pretty boring.
Re: volume. That's what surprises me. I can't imagine that for hours on end. Short period...yeah. But somewhere between the 1st and 2nd song you'd think that it'd get painful.
(Incidentally, the logarithmic scale for decibels means that ear rupture is somewhere around 150 dB)
