In the battle for loudest NFL stadium, victory appears to belong to the Kansas City Chiefs -- for now.
The Chiefs' official Twitter account said Sunday that fans had broken the world record for loudest sports venue during Kansas City's 24-7 victory over the Oakland Raiders at Arrowhead Stadium.
The 137.5 decibels, if upheld, would top the 136.6 decibels set by the Seahawks on Sept. 16, when Seattle topped the San Francisco 49ers in a "Sunday Night Football" beat down.
But don't expect the Seahawks to take this loss lightly.
