KANSAS CITY, Mo. - Chiefs fans are loud and proud, and they proved it Sunday.
It took all 77,500 fans inside Arrowhead to break the record for world’s loudest outdoor stadium. The noise level reached 137.5 decibels.
The local architect of renovated Arrowhead and the previous record holder, Seattle’s CenturyLink Field, said design does make a difference.
Whispering comes in around 20 decibels. At around 125 decibels, doctors say, noise becomes painful.
The noise at Arrowhead shook the ground, broke the record and led the team to victory.
Chiefs running back Jamaal Charles credited the fans with the win.
“I think that's why I was playing so hard -- so physical -- today, because the fans did a great job," he said. "I think we give this win up to the fans because they came out and cheered their hearts out today."
Even without the help of a covered field, fans at Arrowhead reached 137.5 decibels, beating CenturyLink Field's previous record of 136.6.
Seattle has a partially covered field, which you might think could hold sound in better. However, Kelly Kerns, a local architect who worked on both Seattle's and Kansas City’s stadiums, spoke with 41 Action News about their design. He said Arrowhead actually has the advantage.
“At Arrowhead we have a continuous seating bowl without an opening on the end zone like, say, Seattle does, or opening on the corners,” said Kerns.
Also, Arrowhead holds about 10,000 more people than CenturyLink. And the suites in Seattle are enclosed, unlike in Kansas City.
All of which creates a huge hometown advantage.
“On defense, when the other team has the ball, they want the fans to be excited, and players enjoy playing when the fans are excited, so they want the fans to be amped up,” said Kerns.
On Sunday, the noise worked.
“Part of us getting sacks, part of us playing defense, is the crowd," said Chiefs linebacker Derrick Johnson. "That Chiefs nation, the Red Sea, it's crazy out there; you can’t hear anything.”
Kerns said architects don't necessarily design stadiums for maximum noise level. They design them for maximum fan enjoyment.
“That's the kind of thing that people cannot do at home or even at a bar watching the game," Kerns said. "It's that communal experience of going to the stadium and cheering on the team that we always try to emphasize."
