The crowd at Seattle's Lumen Field during the United States' 2-0 World Cup victory over Australia on June 19, 2026 did not surpass the 136.6-decibel mark set by Seattle Seahawks fans during a 2013 NFL game against the San Francisco 49ers — a level certified by Guinness World Records as the loudest crowd roar at a sports stadium. No official decibel measurement confirming a new record was reported from the match.
The most widely covered acoustic story from the game was seismic rather than sonic: a peak crowd reaction during a U.S. goal produced a vertical ground-motion amplitude of 3.3 millimeters per second on nearby sensors, registering as a measurable seismic event. That reading reflects structural vibration from crowd stomping, not airborne sound pressure, and does not speak to whether the 137-decibel threshold was crossed.
Breaking the Seahawks' record would have required sustained, measured crowd roar above 136.6 dB — a figure no reporting agency confirmed. The community was skeptical at 74 percent NO and was correct.
