Well, just for context, I've attended lots of football games (have had Washington season tickets and Michigan season tickets; travelled to lots of venues, including Ohio State, LSU (night game), Notre Dame, Rose Bowl, etc.).
I'd rank this top 5. Probably loudest game I've been too was the epic night game in Husky Stadium in the early 90s against Nebraska. Not sure I'll ever hear anything that loud again. This was a notch below, but still top 5, which is impressive as I've been to a ton of venues and games.
And my throat hurts everytime I talk lol.
