Congratulations, 12th Man.
The Seahawks fanbase reached a noise level of 131.9 decibels during Sunday night's game against the NFC West rival San Francisco 49ers at CenturyLink Field, setting the Guinness World Record for crowd noise.
Former Seahawks defensive lineman Joe Tafoya and his "Volume 12" group were behind the fan-driven effort that set out to top the previous Guinness World Record of 131.7 decibels set two years ago during a soccer match in Istanbul, Turkey.
A record capacity-crowd contributed to the record-setting effort, as the announced attendance of 68,338 marked the largest ever for a Seahawks game at CenturyLink Field. The gathering topped the previous record of 68,331 set on November 12, 2007, in a game that also came against the 49ers.
