How loud did it get in U.S. Bank Stadium Sunday night? Really loud

(KMSP) - U.S. Bank Stadium is one of the loudest stadiums in the NFL, and the reverberations from Sunday's Vikings game are still being felt.

"Nothing has ever been as loud as Diggs getting that touchdown," Carly Lehmkuhl said.

Like most of the Vikings fans at U.S. Bank Stadium on Sunday, Lehmkuhl was screaming in the stands when Stefon Diggs made his historic catch at the end of the game. In fact, two days later, her ears are still ringing.

"Yesterday my ears were still a little sore. Even today, yet. It’s like a slight ear ache. That was loud,” she said.

The Vikings say the loudest readings they got on the field were around 120 decibels - 
but those were before the Diggs catch.

We used a sound meter app on the concourse, and the loudest we measured was 105 decibels, slightly higher than the levels we found at a Timberwolves game, which was 98 decibels. The airport topped out at 90 decibels.

By comparison, the loudest it got at the Metrodome was during game two of the ‘87 world series when the ear splitting cheers registered 125 decibels.

"That would be very much the same as the peak of a Metallica concert," said audiologist Dr. Jason Leyendecker.

Leyendecker said anything over 115 decibels can cause permanent hearing loss in less than 3 seconds.

The roar of the crowd after the “Minneapolis Miracle” went on much longer than that.

"Coming out of that, you would have a hard time understanding people. Getting into crowds where multiple people are talking, you would hear them, but you wouldn't be able to understand what they are saying," he said.

But Lehmkuhl said if the Vikings somehow make it to the Super Bowl at U.S. Bank stadium, “it’s going to be even louder…so earplugs, for sure.”

As loud as the Vikings game was on Sunday, it can't hold a candle to what the Seahawks did to the Saints in 2011; when Marshawn Lynch ran for a 67-yard touchdown toward the end of a wild card game, sound from the crowd was so deafening, it registered as a magnitude 1 earthquake on a local seismograph.
