It is claim they have been saying for years, but after someone from the Guinness Book of World Records was there on Sunday it is now official.

A group of Seahawks fans announced earlier in the week that during Sunday night’s game against the San Francisco 49ers, the crowd at CenturyLink Field would attempt to break the Guinness World Records mark for loudest stadium. During the game, the group in charge of the effort — Volume 12 — announced on its Facebook page it had set the mark late in the first quarter. The decibel reading taken during a sack of San Francisco quarterback Colin Kaepernick in the first quarter — following a one-hour weather delay — was 131.9 decibels.

The previous record for “loudest crowd roar at a sports stadium,” was 131.76 decibels, set in 2011 in Turkey at the Ali Sami Yen Sport Complex Turk Telekom Arena during a soccer match between Galatasaray SC and Fenerbahce. Now the attendance for the Seahawks game was a record at 68,338. I would hope that the Cowboys would beat this record one day considering the stadium could hold over 100,000 people. Unfortunately I know they won't, to many rich people sitting down not wanting to get up and cheer. I know this because I got told to sit down at a Dallas Cowboys game when my team was on defense. This was a Redskins and Cowboys game, the Cowboys were up by 7 points and it was third down. Do you know another NFL stadium where you will get told to sit down by security on a third down on defense?
