Kansas City Chiefs fans have had plenty to cheer about this season, and now they have reason to pat themselves on the back as well.
Chiefs fans set the world record for crowd noise in an outdoor stadium, reaching 137.5 decibels in the final minutes of a 24-7 victory over the Oakland Raiders on Sunday at Arrowhead Stadium, according to Guinness World Records.
Members of the Chiefs organization credit their vocal fans with helping the team improve to 6-0 this season by making so much noise -- comparable to that of a jet engine at 100 feet. Coach Andy Reid said he could feel the ground shaking when the Raiders had the ball.
“The way the crowd was going, that was tough,” Chiefs quarterback Alex Smith said. “I was sitting there on the sideline, and I could tell, it was hard environment to execute in.”
The previous record of 136.6 decibels was set earlier the season by Seattle Seahawks fans at CenturyLink Field. Guinness World Records adjudicator Philip Robertson was on hand to document that effort as well as the one at Arrowhead.
Though the sustained noise level Sunday was higher on Sunday, Robertson said, as the game progressed, it was starting to look as though Chiefs fans might not be able to top the volume of Seattle's infamous 12th man.
But that's when they turned it up a notch.
“In the fourth quarter, they got to 135.4, and that's where we thought they were going to finish,” Robertson said. “Heads dropped, but then the fans really started working together.”
