Seattle wins the decibel battle, but Kansas City plans on winning the decibel war

KANSAS CITY, Mo. — Oh, Terrorhead Returns heard you, Seattle fans. And they’re coming for you.

But not ’til next year.

“We will not attempt at the Colts game (on December 22),” said Tim VanderPol, one of the Kansas City Chiefs fans who founded the group “Terrorhead Returns” in order to encourage Arrowhead Stadium to set a new Guinness World Record for crowd noise at an outdoor sporting event. “Just because we’re not going to be able to plan this out, take care of everything in two weeks.”

VanderPol estimated the costs of bringing in a Guinness adjudicator to Kansas City at between “$7,500-10,000 … it’s not something where you can make a phone call today and have them here next week. It takes months of planning. Of course, (it won’t take) as long, now that we know what we’re doing.”

The Chiefs have just one regular-season home game remaining, the aforementioned visit from Indianapolis just before Christmas. And because of two losses to rival Denver over the past three weeks, it’s unlikely the 9-3 Chiefs will host a playoff game in January, assuming they reach the postseason.

“If we can receive a prime-time game (in 2014), that will be the most efficient for us,” VanderPol said.

Fans of the Seahawks and Chiefs have been hopscotching one another in the Guinness World Records book for the past three months. Seattle set a new mark for loudest outdoor sporting crowd during a game against the 49ers on September 16, raising the old bar from 131.76 decibels to 136.6.

That standard stood for less than a month, though, as Guinness decreed that Arrowhead Stadium had set the new record of 137.5 during the Chiefs-Raiders game on October 16.

Seattle got the last word — or should we say scream? — Monday night, when a Guinness adjudicator registered the noise level at CenturyLink Field at 137.6 dB, barely edging the Arrowhead mark.

As a point of comparison, the sound of a jet taking off from 30 feet away is about 140 dB. The human pain threshold is around 110 dB; at 150 dB, eardrums can rupture.

Still, VanderPol says Chiefs fans don’t plan to surrender this particular volume war without at least one more fight.

“And my second (thought) was, ‘Oh, I can beat that,'” he said of the new Seattle record. “I mean, the last time they set it, we smashed it by .9, and I’m sure with a little more support, we can again accomplish what we want to accomplish.

“And (I’d) really like to shoot for 140 (dB), to tell you the truth. We want to set the bar so high that nobody can (break) it again.”
