KANSAS CITY, Mo. (AP) Even the most muffled clap seemed to echo throughout Arrowhead Stadium last season as the Kansas City Chiefs plodded their way toward one of the worst seasons in franchise history.
A group of fans is trying to restore the roar.
When the Chiefs host the Oakland Raiders on Sunday, they will be trying to break a Guinness world record for loudest sports crowd roar in an outdoor sports stadium that was set earlier this year by Seahawks fans during a game against the 49ers.
The record is 136.6 decibels, or just below what a jet engine sounds like 100 feet away. The fans even have the support of the Chiefs, who paid for a Guinness adjudicator to fly to Kansas City for the record attempt.
The Chiefs and Raiders kickoff on Sunday at noon. You can hear the game on NewsRadio 1350 KMAN from the Chiefs Fox Football Radio Network.
