Bad news , diehard sports fans : all that raucous cheering during games does n’t really help your team win . The honest news program is that it does n’t seem to interpose with thespian ’ performance either .
That was the conclusion of Brenna Boyd , an undergraduate in architectural engineering at the University of Nebraska - Lincoln in Omaha . Shepresented measuring she madeof noise levels at college football game games this morning at theAcoustical Society of America meetingin Jacksonville , Florida . Boyd find the idea for her survey after find out about an ongoing competition among college football game fans as to which squad has the meretricious arena . But she ’s more of a ice hockey fan than a football fan , so she focused her own depth psychology on the noise levels in college hockey stadium .
A sound wave ’s amplitude , or range of drift , determines its loudness . deplume a guitar string very heavily , and it will oscillate at the same frequency as when you pick off it gently , but the sound will be flashy , because its bounty is much neat . That string is moving back and away over greater distance , so it exerts more more mechanically skillful vim . The energy stage ( amplitude ) of any sound is appraise dB ( db ) . A human whisper is about 20 db , while normal conversation is around 60 hahnium . Sound levels at a rock-and-roll concert can reach 110 db . At 130 db , phone will cause bother and possibly damage the spike . The human eardrum will actually erupt at 160 db .
Theworld record for the loudest crowdroar at a sporting consequence is currently held by the fans at Arrowhead Stadium , home to the Kansas City Chiefs . On September 29 , 2014 , the bunch ’s roar hit a whopping 142 decibels . So just how gaudy do college football game get in comparison ?
Michigan Technological University’sAndrew Barnardcollected dataon the noise levelsduring biz , while still a grad student at Penn State . His analysisshowed that when opposing teamshad the ball during home game , the noise level in the university ’s stadium hit 110 decibels—50 times the volume as when Penn State was on offense — peak at 122 decibels . ( You canlisten to vocalise samples here . )
Based on that analysis , Penn State motivate the 20,000 - prat scholarly person cheering section to the southern closing zone , where their shouting would be amplified the most . The idea was to hike up the fans ’ excitement during game by reflecting more of that sound get-up-and-go back into the stands and onto the field . But it also raised business organisation about how well the quarterbacks would be able-bodied to pass with their teammates and coaches give the ramped up racket level .
As sportswriterSean Gregory noted in Timewhile traverse the Seattle Seahawks in 2013 , “ Players have trouble pick up the quarterback ’s instructions , which can cause holdup - of - secret plan penalties and loosely throw an offense out of sync . ” ( Seattle ’s Century Field held the former world record for forte bunch roar , helped by its unique canopy pattern , which amplifies the sunshine . )
Boyd wondered about about the possible impact too . Most ice hockey stadiums have a build - in amplifying broker , since they have closed roofs and hence more surface orbit to reflect good wave . So she speculate that they would be even louder than typically undecided - aura football game stadiums .
The loudest game Boyd evaluate was a match between Nebraska and arch - rival St. Cloud University : middling intensity in the student segment hit 95.5 decibels , top out at about 132 decibels . For comparison , that ’s the equivalent of jackhammer 50 foot away , and the phone of a jet-propelled plane engine about 100 foot away , severally .
She also surveil the players after each secret plan to see whether all that cheering facilitate or hindered their romp . The good news : most reported the noise was n’t distracting , and it did n’t prevent clear communicating between autobus or players during the game .
As for whether all that garish shouting helped the players — not so much . When Boyd matched up her brashness measurements with the events during the biz , she found there was n’t much coefficient of correlation at all , for example , between dB level and how many goal the base team scored . Boyd thinks there was n’t sufficient information to make a unequivocal case either way , however .
So go forward and cheer your lungs out for the home team at live games . Just commend that it ’s more psychologically satisfying to you than the players on the field . And maybeinvest in a pairof ear stopple toprotect your earshot , because those roaring crowds can get hella loud .
