A group of Seattle Seahawks fans—known as Volume 12—have petitioned the people at Guinness World Records to have the crowd noise monitored at Seattle’s CenturyLink Field during the team’s home opener on September 15 against the rival San Francisco 49ers in the hopes that the 12th man will break the record for “loudest crowd roar at a sport stadium,” currently held by the supporters of Turkish soccer club Galatasaray S.K.
The loudest crowd roar at a sports stadium was 131.76 dbA and was achieved by Galatasaray Spor Kulubu (Turkey) at the Ali Sami Yen Sport Complex Turk Telekom Arena, in Istanbul, Turkey, on 18 March 2011.
A peak reading of 131.76 dBA was recorded during the Galatasaray SC v. Fenerbahce SC derby game at the Ali Sami Yen Sport Complex Turk Telekom Arena on 18 March 2011. The record was attempted by Galatasaray SC fans. The sound level was measured from the side line of the stadium. Distance to the crowd was 2 meters. They were given 3 attempts. The first attempt was at 20:50 pm, it measured 112.08 dbA. The second attempt was at 21:03 pm and measured 130.55 dbA. The third attempt took place at 21:15 pm and produced a reading of 131,76 dbA. A notary and one witness (sound engineer) were present. The precision measuring noise level meter (certified and calibrated) was a Bruel & Kjaer 2250 RAM DT-8850.
Considering that the rowdy Seahawks fans once caused an actual seismic tremor during a Marshawn Lynch 67-yd touchdown run in a playoff game against the Saints, breaking the “loudest crowd at a sports stadium” record should be a piece of cake.
