Chiefs fans set crowd noise world record on Monday Night Football
Tuesday September 30th, 2014

Kansas City Chiefs fans' broke Seattle Seahawks' fans' record of having the loudest outdoor stadium by creating 142.2 decibels worth of noise at Arrowhead Stadium Monday night. 

The Chiefs tweeted a celebratory infographic declaring Arrowhead the loudest stadium in the world. 

The sound level, which was recording by an on-site representative from Guiness, is louder than a jet airplane flying 100 feet overhead. 

The stunt didn’t escape the attention of the Seahawks. Seattle tweeted its congratulations of the Chiefs’ efforts, noting its pride that the NFL was home to the two loudest franchises in the world. 

The Chiefs measured the sound level with a handheld Larson Davis sound-level meter, according to ESPN’s Darren Rovell. The Seahawks, however, have unique infrastructure in place to potentially break Monday night’s record. 

CenturyLink Field in Seattle, which also set the previous world record for stadium noise level during a Monday night game, is equipped with two separate built-in seismometers courtesy of the Pacific Northwest Seismic Network. 

CenturyLink Field famously played home to the 2011 playoff game in which a 67-yard touchdown run by Marshawn Lynch incited such a high level of cheering that a minor earthquake registered at a nearby seismic center. CenturyLink has since been commonly dubbed the loudest stadium in the NFL.

 

Since the "Beast Quake" touchdown run, the two franchises have competed back and forth for the record of having the loudest stadium. In October 2013, the Chiefs set the then-record of 137.5 decibels. Last December, the Seahawks upped Kansas City’s record by one-tenth of a decibel, setting a record of 137.6. 

In an attempt to protect fans’ hearing, the Chiefs passed out more than 36,000 earplugs before the game, despite the game’s attendance exceeding 76,000, according to ESPN’s Adam Teicher. 

If the Seahawks want to re-break the Chiefs’ record, the franchise will have to do so with fewer voices in its arsenal. CenturyLink Field’s capacity is only 67,000.
