The fan group attempting to set a Guinness World Records mark for loudest stadium said it has established a record during Sunday night's game between the Seattle Seahawks and San Francisco 49ers. The group called Volume 12 announced that it set the mark late in the first quarter. The decibel reading -- taken during a sack of 49ers quarterback Colin Kaepernick by Seahawks defensive lineman Michael Bennett in the first quarter -- 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. The reading was confirmed by Phil Robertson a judge for Guinness the Seattle Times reported. The newspaper said the stadium's crowd noise got even louder during a third-quarter goal-line stand by Seattle defense reaching 136.6 decibels according to Bill Stewart the sound engineer and partner at SSA Acoustics in Seattle who did the measuring. Volume 12 footed the bill for the Guinness World Records official to come to Seattle and wasn't affiliated with the team. The Seahawks won the game 29-3.
