How Loud is Oregon's Autzen Stadium ?


This is from Wikopedia:

Autzen is renowned for its crowd noise. On October 27, 2007, during a 24-17 defeat of the USC Trojans, a record crowd of 59,277 fans was recorded at 127.2 decibels (louder than a jet taking off).[5] A similarly-loud 31-27 upset of third-ranked Michigan in 2003 prompted a Michigan Daily columnist to write[6]

“ Autzen's 59,000 strong make the Big House sound like a pathetic whimper. It's louder than ... The Swamp at Florida, The Shoe in Columbus, and Death Valley at Louisiana State. Autzen Stadium is where great teams go to die. ”

Michigan coach Lloyd Carr later said that Autzen Stadium was the loudest stadium he'd ever been in.[7]

In 2006, a Sporting News columnist named Autzen the most intimidating college football stadium in the nation.[8]
