During tonight’s rivalry game between the 49ers and Seahawks, the Seattle fans will try to set a Guinness book of world record for crown sound. Century Link field, which is the home field of the Seahawks is widely regarded as the loudest stadium in the NFL. The way it was built, plus it’s crazed fans are the reason. But they want to make it official. Hit the jump.

The Seahawks claim the loudest crowd noise measurement at Century Link Field is 112 decibels, which is not the same as 112 dbA, but still a long way shy of the record.

The second obstacle is making sure the measurement is “official”—or at least accepted by Guinness. It’s not an easy process. The hapless Flyers learned this when they tried to set the record for most people watching paint dry, but failed to even alert Guinness. Volume 12 had to apply before even attempting the record. They were approved back in July. The detailed guidelines they received specify the rules:

The sound level produced must be measured on a Class 1 precision measuring noise level meter, whatever that is. The microphone must be positioned five feet above the ground. The microphone must be at least 2.5 meters (8.2 feet) from the nearest fan. In-stadium music and piped-in crowd noise are not allowed.

Guinness will have a judge on hand to witness the attempt, flown out at Volume 12’s expense. They’ll also need a professional on hand to take the measurements.

The current record is owned by fans of a Turkish soccer team. They only had 53,000 fans for that. The game tonight will have close to 90,000. Watch the video below to see that.
