CenturyLink Field is considered one of the most intimidating stadiums in the NFL, partly because it is so noisy. But a fan group wants the Seattle Seahawks' home to be the loudest stadium on Earth.
The group, Volume 12, is organizing an effort to break the Guinness World Record for "loudest crowd roar at a sports stadium" on Sept. 15 during the Seahawks' home opener versus their hated NFC West rivals, the San Francisco 49ers.
According to the Seattle Post-Intelligencer, which had earlier reported the group's attempt, Volume 12 is not affiliated with the NFL team. However, it has applied with Guinness to attempt the record and posted on its Facebook page that the organization has accepted its application.
The current record for loudest crowd roar is 131.76 decibels, set on March 18, 2011, during a soccer match at the Ali Sami Yen Sports Complex Turk Telekom Arena in Istanbul, Turkey. Fans of Turkey's Galatasaray S.K. club were given three chances to set the record and hit it on their third try.
The Seahawks say Seattle's famed 12th Man has been measured at 112 decibels, louder than a power saw or rock concert but not much more quiet than a Boeing 747.
In Seattle's 2011 playoff victory over the New Orleans Saints, the Seahawks' fans actually made the ground shake during Marshawn Lynch's 67-yard touchdown in which he broke free at the line of scrimmage and then shed several tacklers en route to the end zone.
A seismic monitoring station located about 100 yards west of the stadium registered seismic activity during Lynch's run. The shaking was most intense during a 30-second stretch about the time Lynch broke free from the line of scrimmage, finished off his touchdown and celebrated in the end zone with his teammates.
More than 60,000 frantic fans are expected for that game versus San Francisco.
