SEATTLE, Wash. -- Seahawks fans will attempt to break a world record for loudest fan noise Sunday.
The “12th man” has earned the reputation as the loudest group of fans in the NFL. A representative from Guinness World Records will come to see if they can reach 131 decibels. Rustling leaves are about 30 decibels and standing next to a jet is 108.

Noise levels that loud can cause permanent damage, so a group is donating ear plugs to protect the fans.
