12th Man Guidelines

September 15th Guinness World Records will attend our game as an official judge for the world record attempt.

We get 3 official attempts:  All 3 attempts MUST be taken on September 15th against the 49ers. We will only need 1 to break the record so the next 2 attempts will be an effort to break our own record! There will be no official 1-2-3 GO cue from stadium officials. This is a true organic fan movement for the fans by the fans…Spreading the word is very important!

ATTEMPT #1 will take place on the 49ers 1st offensive possession. Please be in your seat and ready to participate during the opening Kickoff. We need everyone! There is no 1-2-3 Go. Just be loud like we always are and let the recording begin.

-How do we know if the record is broken?

We will notify everyone on the OfficialVolume12 Facebook and Twitter pages immediately following our attempt.

-What happens if we don’t break the record?

We get 2 more attempts, If it doesn’t happen after the final attempt, we will officially be the Loudest Stadium in the NFL.

Seattle’s 12th Man

After Seattle’s big 1983 playoff victory at Miami, Knox said “this team does not play alone, we play with an extra man, a twelfth man — our fans.” Before the final game of the 1984 season, the Seahawks retired the number 12, meaning it could never be worn by any players; it was a symbolic act unprecedented in professional sports.

Kingdome crowds were so loud that visiting teams couldn’t hear their quarterbacks’ signals, prompting a 1989 league rule saying such disruptions would cost the home team a 5-yard penalty and a time out. Knox fought with the league to NOT quiet the crowd with penalties and the rule was rarely enforced.

 That crowd noise followed the Seahawks into their new stadium in 2002. In recognition of the home field advantage fans helped create, the Seahawks installed a flagpole above the south end zone in 2003 and made the raising of a 12th Man flag part of every pre-game ritual. Our identity was molded by the ones before us. ‪#‎Volume12‬
