Definitely hyperbolic, but the dome has been loud for decades, and with the new roof - they really could break records. In the Penn State game from 1987, the on-field reporter had a dB meter at the beginning of the game and said they'd be registering the volume all day. I need to go through the game and see if they ever went back to him on noise levels.
I swear I recall during the 1992 Miami-SU game, the on-field reporter saying the dB meter they had registered 140, or two jumbo jets taking off simultaneously (I believe when Dan Conley intercepted the ball early in the game). I will need to find that game and see if I can find that quote. Maybe I was just a very excited 15-year-old and misheard him.
Either way, hopefully, The Post-Standard does a dB meter story for this game, it will be interesting with the new roof. Just as long as the game doesn't go the way of the Clemson game in 2019.
