http://www.cbssports.com/nfl/eye-on...ets-guinness-world-record-for-loudest-stadium Back in July, we first mentioned that the 12th man -- the name Seahawks fans go by -- would use the Week 2 matchup against the 49ers to try to break the Guinness World Record for the loudest stadium in sports history. It didn't hurt that the Seahawks dominated the 49ers on Sunday night. During a third-quarter goal-line stand, CenturyLink Field reached 136.6 decibels, shattering the previous mark of 131.9 set by ... the 12th man just two quarters earlier. The Seattle Times confirmed the result with Phil Robertson, a judge from Guinness. Coming into the game, fans of Turkish soccer club Galatasaray S.K held the record of 131.76 decibels, set in March 28, 2011. Robertson, who is more familiar with soccer venues, was impressed with Seahawks fans. "It's a far louder, tribal kind of passion," and "the sound is more continuous," he said. "There's passionate people in soccer, but here you see veins bulging out of necks."
