The Kansas City Chiefs are in the Guinness Book of World Records. They set the record for loudest crowd noise in a sports venue in 2014 when a 142.2 decibels reading was registered at Arrowhead Stadium.
The Chiefs are not as prominent in the NFL playoff record book. In fact, the loudest stadium in the NFL hasn’t witnessed a playoff victory in more than 23 years.
Since the Chiefs won Super Bowl IV after the 1969 season they are 4-14 in playoff games. Last season, they snapped an eight-game playoff losing streak, the longest postseason losing streak in NFL history.
