In the course of play, it's absolutely a violation and fans can be asked to leave the stands. Outside of the course of play (e.g. after goals, saves, etc.), I believe it's allowed (annoying, but allowed).
sorry. The Bay student section was a great, loud audience & they had a handful of vuvuzellas that sounded like LOUD, dying geese. I edited on mute cuz I didn't want to hear the obnoxious sounds all over again (after living thru it live)
@@us57637 - because I warned not to wear headphones while watching this game? As another commenter pointed out, this wasn’t even supposed to be allowed as they were playing it during play.
