Four weeks after the fine folks at CenturyLink Field in Seattle, affectionately known as the 12th man, set the Guinness World Record for the loudest stadium in sports history in the Seahawks' blowout win over the 49ers, fans at Arrowhead Stadium will attempt break it when the Chiefshost the Raiders this Sunday.
A representative from the Guinness Book of World Records will be on hand to see if the Arrowhead crowd can surpass 136.6 decibels, the month-old record that shattered the previous mark of 131.9 set by … the 12th man earlier in that 49ers-Seahawks game. Previously, fans of Turkish soccer club Galatasaray S.K held the record of 131.76 decibels, set in March 28, 2011.
Guinness judge Phil Robertson, who is more familiar with soccer venues, said he was impressed with Seahawks fans.
"It's a far louder, tribal kind of passion," and "the sound is more continuous," he said at the time, via the Seattle Times. "There's passionate people in soccer, but here you see veins bulging out of necks."
To prepare for the noise, the Raiders pumped in crowd noise during practices this week, and will use a silent count during the game.
“We work that every week,” Raiders coach Dennis Allen said, via CSN California. “We work that when we're on the road. We work that when we're at home because the defense has to deal with crowd noise too. Crowd noise can be beneficial at times, but it can be a factor for their defense too.”
The Chiefs are 5-0 for the second time in franchise history, the last coming in 2003. That team started 9-0, and finished the regular season 13-3 before losing to the Colts in the divisional round of the playoffs.
