Volume 12, a fan group, is planning to break the Guinness World Record for "loudest crowd roar at a sports stadium" when the Seahawks host the San Francisco 49ers in Week 2 at CenturyLink Field, known affectionately to fans as "The CLink".
The current record holder is 131.76 decibels, set during a soccer match at the Ali Sami Yen Sport Complex Turk Telekom Arena in Istanbul, Turkey, on March 18, 2011.
CenturyLink Field holds more than 60,000 people, and the stadium was specifically designed to enhance acoustics, making it an intimidating atmosphere. According to the official site, opposing teams average 2.36 false starts per game, the highest in the NFL. The crowd has been recorded at over 112 decibels, almost as loud as a Boeing 747 engine. During Marshawn Lynch's 67-yard touchdown run in the 2011 playoffs, the crowd was loud enough to trigger a small earthquake.
