The Kansas City Chiefs and the team's fans have long prided Arrowhead Stadium as being the loudest stadium in the NFL, but losing seasons cost fan support and decibels.
The Seattle Seahawks fans managed during a Sunday Night football game last month to capture the official designation of loudest stadium from the Guinness Book of World Records.
And rather than an unproven boast, Chiefs fans are working to steal the designation from the Seahawks. Fans are paying for a judge for Guinness to fly into Kansas City to assess the noise level that could equal gunfire or a jet taking off.
Ty Rowton is a leader of the endeavor.
"We're saying, 'No way. We're the loudest stadium in the NFL and soon in the world,'" he said.
The record set by Seattle during the third quarter against the Niners was 136.6 decibels. The previous record was for a soccer game in Turkey.
Guinness doesn't allow air horns or horns of any kind, whistles or artificial noisemakers. So if you are going to Arrowhead to see the Chiefs take on the Raiders, leave the horns and whistles at home and work on your cheering and screaming skills.
"You have to multitask," Rowtown explained. "You have to scream like a little girl. Either cup your hands or roll up your program and make a megaphone. Stomp your feet. You have got to pound on the seat in front of you. Do absolutely everything you can to make the most noise."
For years, opposing players dreaded coming into Arrowhead and false start penalties by the visiting team were common.
And in another sign of how popular the Chiefs are now that they are undefeated, CBS is broadcasting Sunday's game at noon to most of the country. The Met Life blimp was hovering over downtown Kansas City on Wednesday.
During the Chiefs more illustrious years, it was a frequent site to see blimps flying over the Kansas City skyline.
"The Guinness World record is just part of it. We're trying to restore Arrowhead to the way it was in the '90s as the most intimidating place in the world," Rowton said. "Opposing players just hated coming to Arrowhead. It scared them to death and our players got inspired to do amazing things."
Fans are advised to bring earplugs to protect their hearing and throat drops to help soothe hoarse throats.
