I am sorry, at no other point in that game it was as loud at that, nor as LONG as that. The game was insane, but that momment was at another momment altogether.

But all that is beside the point.

I have enjoyed the thread. I don't see where the fun got sucked out. Then again I can talk audio all day and this was a nice change of pace on the rant.

I agree. Thanks for the help to both of you and for helping me understand this a little more. It is pretty interesting when you have seen it applied.

Anytime. And yes it is very interesting. Thats what I love about this field, there is always something to learn and every situation forces you to think differently about sound.

I would really love to do the computer simulations but that would be a major, major project. I would literally need measurements of every surface area exposed to the field for both stadiums and I would have to build them connecting one dot at a time. It is a great program for concert halls/churches but a stadium is taking it to a whole other level. Maybe one day.......

Knowing what we know about the "Earthquake Game", Is it possible to estimate the sound necessary to generate seismic movement over a mile away?

That TD had to crack that 130 mark. I'll bet somewhere around 132?

Well if you had the acoustic properties of every physical object in between that seismograph and the stadium at that very moment then yes you could.

I think people jumping up and down caused that seismograph to go off more so then sound did.

That's kind of what I want to know also. It is amazing though that Autzen does that with what mid 60s attendance? The acoustics in that stadium must be almost a perfect stadium with the built into the ground etc. I also would be curious to know what enclosing the end zones would do to the decibel level. It is really awesome to think that I witnessed the loudest registered outdoor sporting event in atleast American history.

They recently renovated the stadium and added seats. A big concern was that the noise level would go down because of a change in the architecture that would have a negative impact on the acoustics. It didn't happen though. It is as loud as before the addition. I didn't notice an increase in the noise either, which is interesting.

I've never been to Tiger stadium so I can't comment firsthand on it's loudness. I am sure it is though.

Pretty much the loudest a stadium can get period.

I was at basic training for the Earthquake game, so I can't speak to that. I also missed the first victory against Alabama in TS, which I'm sure that was big (did get to watch that one on TV). I was at the "Bring Back the Magic" game against Auburn, in which we won on the last play interception by Troy Twillie in front of the student section. That was pretty much as loud as it had ever been in the stadium while I was there. The announcement of the USC loss to Stanford during the Florida game is pretty much the theoretical limit to human beings making noise in Tiger Stadium. It would require some mechanical or electonic assistance to exceed that. I don't know where the 129.8 was recorded, but that means that 130 isn't possible.

For those of you who were there, you know what I'm talking about when I say: The noise came from somewhere else, ethereal and "other worldly". It was as if we all just collectively, and simultaneously invoked it.

I have heard the only way to tell which is the loudest is to put your ear to the ground near each stadium. Watch out for Buffalo and approaching trains.

In this program I will build models of both stadiums, simulate some noise, and then I will be able to physically see the sound. Then we will know which stadium is truly the loudest

i dont see how that would be accurate. your talking strictly about potential of a stadium and withholding the fans influence. or maybe your not--but it seems your saying which stadium is the loudest. not which stadium GETS the loudest. So if jordan hare comes back as the loudest after your tests, then what does that prove? That the stadium is built to produce more noise? That would also prove our fans are even more loud if we have higher decibels in a stadium that is not made to be as loud. I always thought the argument and the pride came from our fans being the loudest. not the way the stadium is built.---

Decibel (Loudness) Comparison Chart
Here are some interesting numbers, collected from a variety of sources, that help one to understand the volume levels of various sources and how they can affect our hearing.

Environmental Noise

Weakest sound heard 0dB
Whisper Quiet Library 30dB
Normal conversation (3-5') 60-70dB
Telephone dial tone 80dB
City Traffic (inside car) 85dB
Train whistle at 500', Truck Traffic 90dB
Subway train at 200' 95dB
Level at which sustained exposure may result in hearing loss 90 - 95dB
Power mower at 3' 107dB
Snowmobile, Motorcycle 100dB
Power saw at 3' 110dB
Sandblasting, Loud Rock Concert 115dB
Pain begins 125dB
Pneumatic riveter at 4' 125dB
Even short term exposure can cause permanent damage - Loudest recommended exposure WITH hearing protection 140dB
Jet engine at 100', Gun Blast 140dB
Death of hearing tissue 180dB
Loudest sound possible 194dB

OSHA Daily Permissible Noise Level Exposure
Hours per day Sound level
8 90dB
6 92dB
4 95dB
3 97dB
2 100dB
1.5 102dB
1 105dB
.5 110dB
.25 or less 115dB

Perceptions of Increases in Decibel Level
Imperceptible Change 1dB
Barely Perceptible Change 3dB
Clearly Noticeable Change 5dB
About Twice as Loud 10dB
About Four Times as Loud 20dB

Sound Levels of Music
Normal piano practice 60 -70dB
Fortissimo Singer, 3' 70dB
Chamber music, small auditorium 75 - 85dB
Piano Fortissimo 84 - 103dB
Violin 82 - 92dB
Cello 85 -111dB
Oboe 95-112dB
Flute 92 -103dB
Piccolo 90 -106dB
Clarinet 85 - 114dB
French horn 90 - 106dB
Trombone 85 - 114dB
Tympani & bass drum 106dB
Walkman on 5/10 94dB
Symphonic music peak 120 - 137dB
Amplifier rock, 4-6' 120dB
Rock music peak 150dB

TIGER STADIUM IS FREAKIN LOUD!!

If this thread continues and I read all posts, who can I request my PHD certificate from. It'll be in Deciblology.

Geauxdan, PHD, deciblology. Thank you.

Or could it be "dBology"

Well to simulate crowd noise I would need to take a small speaker in the program, adjust the volume level on it so it simulates the amount of noise one person can make, then copy and paste that speaker placing one in every seat of the stadium and aiming it towards the field. This would then show a color spectrum over the field where each color can represent a different dB level. Therefore I would be able to find the "hot zone" of noise and could tell you pretty much how loud it gets on the field, and anywhere else in the stadium for that matter.

Yep. It would show how sound is reacting to the environment it is being produced in.

Exactly. Sure E.A.S.E. would give us some fun numbers to compare the two stadiums with but the truth is you could never truly simulate the fans. For example some people only clap, some scream and clap, some scream while clapping and stomping their feet (that would be me). The program would give us a ton of answers but the truth is fans are unpredictable.

Your absolutely right. It is the LSU fan base that puts our noisy stadium a step above others. First off while other places might make noise.....no place makes noise as long as we do. Remember at least half of the stadium is liquored up and drunk people seem to have an ability to scream at the top of their lungs much longer than a sober person would.

I can't see the image in the second post....

Is it a graph or stadium rankings?

TigerMonkey’s idea is interesting but it seems like it would only tell us which stadium is most conducive for noise not necessarily which stadium’s fans make the most noise. Rather than try and model each stadium’s acoustics, why not secure sound/decibel meters to the top of each pole on the two goal posts. This would allow a common approach to each field/stadium. One good test is worth a thousand expert opinions.

PS: yell from your diaphragm not your throat. You can make a lot more noise a lot longer that way.
