The Seattle Seahawks broke the world record for 'loudest roar' in the first quarter against the San Francisco and then broke it again in the fourth when running back Marshawn Lynch scored a touchdown.

The effort was organised by former Seahawks player Joe Tafoya and his group Volume 12 and he tweeted from the game that the '12th man' had broken the record during an organised cheer in the first quarter.

The initial cheer hit 131.9 decibels, loud enough to break the record of 131.75 but when Lynch walked in a TD early in the fourth, the crowd erupted into a cheer that registered at 136.6 decibels.

The sound is more than that of being front-row at a rock concert and isn't too much quieter than a Boeing 747 taking off.

The attempt was considered dangerous by audiologists, with Julie Arenberg Bierer of the University of Washington saying: "At the very least people are going to have temporary hearing loss. Most likely they’ll have a little bit of permanent hearing loss.

"I would encourage people to at least cover their ears during the few minutes that they’re trying to break the record."
