I watched half the game since I was bored, and it was pretty loud for only lower bowl of the arena.
The PNC Arena is shared by both the Hurricanes and NC State men's basketball, and NC State's club team does use the Canes practice facility in in Morrisville. If NC State did make the move to go NCAA D1, they could work out a way with the Canes to have NC State hockey games and NC State men's basketball games. PNC Arena is too big for NC State to have hockey there, but I think it really could work.
