LSU commented that they never knew there was a stadium outside of the SEC that could be so loud. The comments were made when the Tigers visited Husky Stadium, home of the Washington Huskies a few seasons ago.

Husky Stadium has long been reckoned as one of the loudest stadiums in the nation. This is in part due to the stadium's design; almost 70 percent of the seats are located between the end zones, covered by cantilevered metal roofs.
At times, the high decibel levels typical of Husky games (especially from fans stomping their feet in the bleachers) causes television cameras to shake. During the 1992 night game against the Nebraska Cornhuskers, ESPN measured the noise level at over 130 decibels, well above the threshold of pain. This is the highest decibel level ever recorded for a college football stadium
