It has been an ongoing battle between the Seattle Seahawks and Kansas City Chiefs for a while now and it has now taken its newest turn.
The race for the World record for the loudest outdoors sports stadium is one that technically never can end, but with each effort, you have to wonder how it can be beaten?
The Chiefs and the Seahawks have been tussling with the record for a while and during Monday's game with the New England Patriots, the Chiefs won it back.
In December 2013, the Seahawks famously took the record from the Chiefs by just 0.1 decibel.
After the Chiefs set a record of 137.5 decibels, the Seahawks soon took their place at the top of the list with an attempt of 137.6 decibels.
But during the Patriots game, the Chiefs fans didn't just beat it, they smashed the record with an enormous effort which reached 142.2 decibels!
They have now officially reclaimed it in the Guinness book of world records and tweeted during the game saying: "It's official! 142.2 is a new @GWR record."
It will now be interesting to see how the 12th man in Seattle will attempt to come back and reclaim their title as the loudest outdoor sports venue in the world.
On top of the pile
The Chiefs are once again on top of the world record list and join some very prestigious company in the record list.
At the time the Seahawks set the record in December, the top five loudest moments in sports venues included two NFL teams, one NBA team, a college football team and a soccer team.
Obviously, the Chiefs and Seahawks were the two NFL teams while in third on the list was Turkish soccer team Galatasary.
Joined by the Sacramento Kings of the NBA (who hold the record for loudest indoor sports venue) the Clemson Tigers college football team, the Chiefs now top an impressive pile.
To much for New England
The Chiefs ran out comfortable winners over the Patriots on Monday night with an impressive 41-14 win.
The star performer on the night was Chiefs Runningback Jamaal Charles who scored three touchdowns in the game - one rushing and two receiving.
The Chiefs scored five touchdowns on the night including a pick-6 thrown by star Quarterback Tom Brady.
The Patriots managed two touchdowns of their own but with Kansas' two successful Field Goals added to their touchdowns, it was an insurmountable performance by the Chiefs.
