Loudest Stadium
Posted on 9/22/08 at 9:44 pm
Posted on 9/22/08 at 9:44 pm
I asked a guy with a doctorate in physics and astronomy what the difference in actual sound heard between 129 (Tiger Stadium) decibels and 127 (Autzen sp?) decibels. He said the noticeable sound to a human would be minimum. He said humans normally have to have a scale of 10 decibels for their to be an extreme noticeable difference. I just thought this could clear up some debate that was going around before about the difference in sound level of the stadiums.

where do you find these ratings listed?

I don't know if they are the exact numbers, but it is what I remembered from the numerous offseason threads on the topic. They could be a little off, but the main point is that there is hardly a difference in the two stadiums.

The decibel's logarithmic scale, in which a doubling of power or intensity always causes an increase of approximately 3 dB, corresponds to this perception.

Autzen registered 127 during the SC game last year. I've heard TS reached 129 after anouncing the SC-Stanford score, but I don't have a link.

ESPN recorded 129.8 after the USC annoucement.
Pretty much the loudest a stadium can get period.

I was at the Oregon-SC game and I thought my head was going to explode when I left. I can't even imagine what 129 is like

I'm not sure why you are shaking your head at my use of doctorate, but this is what the man told me. I am by no means saying this is the gospel as I am ignorant on this conversation as it gets that in depth.

I think he bolded the wrong thing it should have been

Because apparently a doctorate in physics doesn't understand log scales.
Values double for every interval of 2.718

I know that variables theoretically double. And that is what he said, but he said that studies have shown that in a practical setting, our hearing does not necessary respond completely in line with the log 10 scale.

I am not. But we are talking about the difference of about more than 9 times the energy difference.
And I am not just talking out of my arse. Look up studies on auditory sensitivities. At human's most sensitive frequencies they can pick up the difference at .25 dB. On average across the frequency span, it is about 1 dB.
No where near 10.

Don't confuse facts with science. Tiger Stadium during a big game is louder and produces more movement and energy in the air than the movement of the continental plates of the Earth.

Look the guy might of been mistaken or just trying to over simplify it for me. I'm not trying to argue with you, but even with what your data is saying, 1 db produces a noticeable difference, but would this difference be significant to the overall sound at 129 dB? Just asking I do not know the answer.

We could seriously settle the debate of loudest stadiums. Someone get me the architectural blueprints to TS and JH and I will enter them into a program I know how to use called E.A.S.E. (Enhanced Acoustic Simulator for Engineers). 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. Yeah I know its all very geeky but I love it.

It is loud enough to cause hearing damage

Are you serious? Kinda hard to tell. If you aren't
If so,

technically yes 1dB would make a difference but your not going to notice it. Especially when comparing stadiums. The simple fact is that the human brain does not remember noise that accurately. You would have to be able to switch back and forth from TS to JH within seconds of each other multiple times before you could start to pick up on any differences with your ear.
