It was 20 years ago that Kansas City set the world record for loudest crowd roar in an outdoor sports stadium at 116 decibels. This week against Oakland, the Chiefs re-energized fan base hopes to break the new record of 136.6 decibels set at a Turkish soccer game.
"To get that experience back in Arrowhead and really feel it again, and get that excitement back is really fun," Chiefs season ticket holder Eric Kramer said.
Arrowhead Stadium hasn't reached its full potential in recent years. Through the last six seasons, the Chiefs have had a winning record once, but the recent success has season ticket holders like Kramer reminiscing about Arrowhead in its prime.
"I remember going to a Broncos game where Pete Stoyanovich hit some 53-yard field goal or something like that at the end of the game and the place just erupted. It hasn't been like that."
The tone for the 2013 season was set during training camp when new head coach Andy Reid and the Chiefs drew record crowds to practices, and the team noticed.
"What a great atmosphere out here," quarterback Alex Smith said entering his first training camp with Kansas City. "This is new for me. Definitely new territory for me, and it was fun with the energy the fans bring out here."
"It was great to see the fans out here," Reid said. "Looked like they packed the place."
Those crowds now make it to Arrowhead on Sundays with the Chiefs off to a 5-0 start, but it will take a lot from the folks in the stands to make a mark among the Guinness World Records.
"It's going to take two things, the first is that every fan in the stadium has to be rooting as loud as humanly possible," Dan Israel said. Israel serves as the executive producer of the Chiefs Radio Network. "The second is it has to be a full house. There can't be a single empty seat."
"When that place is rocking, there is no doubt about it: they're the loudest stadium in the NFL without a doubt. They're louder than most indoor stadiums," Kramer said.
The goal on Sunday is 137 decibels, but the Chiefs will settle for a hostile environment to disrupt their AFC West rivals.
