Seattle will be calling upon its “12th MAN” on Sunday in an attempt to break the Guinness World Record for loudness at a sports stadium. According to the team website, crowds at CenturyLink Field have produced roars upwards of 112 decibels – or pretty much the same amount of noise that a Boeing 747 makes.
The current record was set at a soccer match in Istanbul, Turkey in 2011, and sits at 131.76 decibels – or louder than a Boeing 747 which is typically around 130.
According to Nick Eaton at the Seattle Post-Intelligencer, “fans will be directed by the stadium’s big screens when an attempt is about to begin, fans will have – at the most – three attempts to break the record, Guinness will have an official ‘adjudicator’ dressed in an official Guinness World Records suit on the sidelines with a Guinness-approved sound meter, and fans should know immediately whether they have broken the record.”
Seattle fans have long prided themselves on their ability to be loud and intimidate opposing teams with their hooting and hollering. Since 2005, they have helped cause 121 false start penalties, the most in the NFL. 67,000 of them will have their chance to be the loudest sports crowd in the history of the world on Sunday.
