The Bears’ matchups vs. AFC West opponents take the team to Kansas City’s Arrowhead Stadium, where they meet the Chiefs on Sunday. In debates over toughest stadiums to play, Arrowhead is always in the discussion, though the Chiefs have struggled this season and sit at 1-3. Like most NFL teams, Kansas City fills its seats to roughly 76,000. And one thing you can say about those nearly 80,000 fans is they are loud. How loud? Arrowhead holds the Guinness World Records mark for loudest crowd roar at at a sports stadium, set in 2014. This will be the sixth time the Bears have played at Arrowhead since the 1973 season, when it opened. Of those five games the Bears went 2-3, needing overtime in one of the victories.

How loud can arrowhead get? In filtered decibels (dbA)

The stadium has a reputation for noise. The record-setting roar measures louder than fireworks, power tools and some gunfire.


Extended exposure to noise of 85 dbA or louder may lead to hearing loss.


An NFL noise rivalrly

Kansas City and Seattle (CenturyLink Field) have been competing in a crowd-noise space-race of sorts, with the record moving back and forth four times over a little more than a season. Arrowhead sits atop the record books, for now.



Does a loud crowd translate into home wins?

Arrowhead’s loud reputation hasn’t always meant victories for the Chiefs. Since 1970, the team is in the middle of the pack in home wins, and more recently in the bottom of the league at home.
