The Kansas City Chiefs stayed undefeated by defeating the Oakland Raiders 24-7 on Sunday, Oct. 13, 2013, as they moved to 6-0. There was more good news and it was that Arrowhead Stadium was officially recorded as the loudest stadium thanks to all of the noise made by the fans on Sunday afternoon, according to a report from ESPN.
During the final minutes of the Chiefs' victory, the world record for an outdoor stadium was broken as the fans hit 137.5 decibels.
The previous record was set earlier this year by the fans of the Seattle Sehawks as their team defeated the San Francisco 49ers. That record was 136.6, but an official from Guinness World Records said on Sunday that the Chiefs fans made Arrowhead the loudest stadium.
"I had people who'd been coming to Chiefs games for decades come up to me and say, `I've never heard it that loud," said Chiefs chairman Clark Hunt, whose family's franchise has long claimed that Arrowhead Stadium is the loudest in the league. "It's very difficult for a team to play in that."
For those that weren't there, let's get some perspective. A jet engine at about 100 feet in the air, sounds off at close to 140 decibels.
Fans of the Chiefs had the record in mind and the franchise even paid $7,500 to have an official fly out to make sure the record was broken. Philip Robertson from Guinness did officially say that the Chiefs fans had the loudest stadium as opposed to the record from earlier this year at CenturyLink Field in Seattle.
