Kansas City Chiefs fans attending Monday’s night game at Arrowhead Stadium against the New England Patriots, broke the all-time record for the loudest fans at an outdoor venue in all of sports.

KC Fans broke the record last season, and then lost it to the Seattle Seahawks, but tonight they outdid themselves by reclaiming the record registering a staggering reading of 142.2 decibels in the first half of the game.

Compare that to a jet engine at about 140 decibels.

Guinness World Records was on hand to record the noise level. The previous record was 137.6.
