Kansas City Chiefs break Seahawks 12th Man's Guinness World Record for crowd noise

Posted Oct 13, 2013

The Kansas City Chiefs set a new Guinness World Record for crowd noise with a 137.5 decibel reading at Arrowhead Stadium.

Less than one month after the 12th Man lifted Seattle's CenturyLink Field into the Guinness World Record book for loudest crowd roar at a stadium, the Kansas City Chiefs and its fans have taken the torch.

According to the team's official Twitter account, Chiefs fans recorded a decibel reading of 137.5 late in the fourth quarter of today's game against the Oakland Raiders at Arrowhead Stadium, topping the previous record of 136.6 set on September 15 by the Seahawks 12th Man in the team's Sunday Night Football game against the San Francisco 49ers.

In addition to the record-setting effort in the stands, it was a record-setting effort on the field for the Chiefs. The club improved to 6-0 on the season with a 24-7 win over the Raiders, joining the 1956 Detroit Lions as the only teams in NFL history to start 6-0 the year after having the NFL's worst record (2-14 in 2012).

Former Seahawks defensive lineman Joe Tafoya and his "Volume 12" group were behind the fan-driven Seahawks effort that set out to top the then-previous Guinness World Record of 131.7 decibels set two years ago during a soccer match in Istanbul, Turkey.
