In week 2 of the NFL season, fans at CenturyLink Field in Seattle broke the Guinness World Record for the highest peak decibel level — 136.6 decibels — ever recorded at a stadium.
Since Seattle’s stadium opened in 2002, its raucous fan base, dubbed the 12th Man, has given opponents fits. Players have trouble hearing the quarterback’s instructions, which can cause delay-of-game penalties and generally throw an offense out of sync. The noise clearly bugged the San Francisco 49ers. Seattle walloped the defending NFC champs on Sunday night, 29-3.
