The Seattle Seahawks’ “12th Man” has long been known for its ability to impact its beloved team’s game in a positive way.

And now those noisy fans are receiving accolades of their own.

According to the fan group Volume 12, the crowd at CenturyLink Field on Sunday night for the Seahawks’ game against San Francisco set a Guinness World Records mark for “loudest crowd roar at a sports stadium” when it hit 131.9 decibels after a sack of 49ers quarterback Colin Kaepernick during the first quarter.

The previous record of 131.76 decibels was set during a soccer match between Galatasaray SC and Fenerbahce at Turkey’s Ali Sami Yen Sport Complex Turk Telekom Arena back in 2011.

But the infamous 12th Man was just getting warmed up. During another defensive stand by the Seahawks in the third quarter, the crowd broke its own record by reaching 136.6 decibels, according to Bill Stewart, a sound engineer and partner at SSA Acoustics in Seattle who was brought in by Volume 12 to do the measuring.


Phil Robertson, the Guinness judge brought in to document the occasion, said the noise exceeded that of the soccer crowds he’s more used to. “It’s a far louder, tribal kind of passion,” he said. “There’s passionate people in soccer, but here you see veins bulging out of necks.”

Seahawks fan Lorin Sandretzky said: “I don’t think I’ve ever heard the sound louder than that. It was incredible. Everybody’s so fired up about the record I think they’re forgetting about the game.”

Oh yeah, that. The Seahawks spanked their NFC West rivals, 29-3, just in case anybody in Seattle has anything left of their voices to cheer with.
