Watch out Seattle fans, Kansas City Chiefs fans are coming for your record.

According to a report from the Associated Press, via the USA Today, Chiefs fans will be attempting to break the Guinness World Record for loudest crowd roar Seahawks fans were able to set in their team’s 29-3 victory over the San Francisco 49ers back on September 15th.

Seattle set the record with a noise burst of 136.6 decibels, breaking the previous record of 131.76 that was set at a soccer match in Turkey back in 2011.

Now, Kansas City will get their crack at it on Sunday against the Oakland Raiders.

A Guinness World Records adjudicator will be on hand – paid for by the team at a cost of $7,500 – and even Chiefs players are feeling sorry for the noise the Raiders will have to deal with.

“It’s tough to imagine that, man,” Chiefs safety Eric Berry said. “Just the games I’ve been a part of it, it’s already hard to get our calls. I can be standing right next to (cornerback Brandon) Flowers trying to get a call to him and he can’t hear me. I’m screaming at the top of my lungs. So imagining it getting even louder is unimaginable.”

If the attempt is anything like the one Seattle did last month, here is what Chiefs fans can expect:

“Fans will be directed by the stadium’s big screens when an attempt is about to begin, fans will have – at the most – three attempts to break the record, Guinness will have an official ‘adjudicator’ dressed in an official Guinness World Records suit on the sidelines with a Guinness-approved sound meter, and fans should know immediately whether they have broken the record.”

There will be about 10,000 more Chiefs fans than were Seahawks fans at Arrowhead on Sunday. Good luck?
