It's the second time this season Seattle's 12th man has broken the Guinness Book of World Record for loudest crowd roar. The record was broken when the noise level reached 137.6 decibels in the second half of the game.


The Seattle Seahawk fans claimed the record back from the Kansas City Chiefs fans when they set the record back in October. The Guinness Book of World Records will now have CenturyLink Field as the loudest crowd of all time. There is even a tee-shirt to commemorate the event. Way to go 12th man you rock loud and proud.
