Decibel level

Clearly we need a occupational health person or audiologist to bring their sound pressure gauge to the games and get some hard data!!

Just don't count home openers, semi final games, or the Cat game. Those games shouldn't factor into comparing WGS to another stadium because they are louder than other games.

I have audio readings (db) at WGS going back to 1991..............99% of the games I attend I have readings for.

For those of you that are interested... I will probably be doing my senior project on occupational noise exposure for coaches & referees at college football games. I'm working out some of the logistics, but I am planning on doing it next fall.

If WGS was 116, and Arrowhead was 137, Arrowhead sounds over 4 times louder than WGS.

No, each increase in 10 on the db scale is equivalent to an increase of 1 power of 10, on a power scale.

Since Arrowhead is 137 db and Wa-Griz is 109 db (unorganized, BTW), Arrowhead produces 10^[(137-109)/10] or 631 times more power. However, power is not linearly related to "loudness" in whatever units one measures, so you can't say Arrowhead is x times as loud.

A better way to compare is just to find common sounds that measure at certain db levels.

Jet engine at 100 feet: 140 db
Power saw at 3 feet: 110 db

I was just going off of the paper from the University of Wisconsin. They might not know what the fuck they are talking about due to all fat rolls in their eardrums, but they say you can roughly determine perception of loudness.
20dB = 4x times increase in perception of loudness. I think it seems impossible too.

Perception of Loudness (20dB = 4x)

Interestingly, our perception of loudness is not the same as sound pressure level. Although the actual formulae
is somewhat complex, as a rough rule of thumb, an increase of 10db SPL is perceived to be approximately twice as loud.

Thus a 20 Db gain would seem to be about 4 times as loud.
And a 40 Db gain would seem to be about 16 times as loud.

I was told that there wasn't going to be any math. Fuckers!

It's be interesting to see how loud WGS is with an organized reading instead of a random sample.

I always thought they should have a meter on the scoreboard, that would challenge the fans to get even louder.

I hope it's loud Saturday so I can blame that for what my wife calls "selective hearing." Should be able to ride that excuse until Halloween at least.

About 5 years ago I sent an email to ODay telling him I would set that up for the stadium using my own equipment. They were not interested in doing it.

It would be cool

Give it another shot, maybe Haslam would be cool with it!

That would be cool, and the crowd would go nuts feeding off it.

Just curious, what did you get that for?

I think it was to measure screamin beagle's mom.

Used a Decibel meter app on my phone 2 yrs ago for a play off game. I was in the North Endzone registering 116-117 decibels when the other team was on offense. Who knows how accurate my phone with an app is but sounds like it was close to what the 'official' records are. Think it was the UNI game.

I allways wanted those dumb scoreboard things in the corners of the field to be decibal meters on 3rd downs. Or atleast doing something cool like that!

True

The gear I have is around $550 it's a pro grade meter. I have a 1khz precision calibrator to properly set your baseline. It has an one external mic input as well as the standard built in mic. The display is digital or analog and I can measure SPL within +/- .5db

That's not bad. I don't know why they aren't interested, maybe not on every play but third downs and every down when the enemy is pinned down in the north end zone, that would be f'in loud

Phone apps are close but I would guess +/- 5-7db from being accurate it also depends on where you are in the stadium when you take measurements.

FYI.... UNI game wasn't that loud but the 09 App St game was

 

[get'em_griz]

After several years of trying to get some sort of false start counter in the stadium, athletics FINALLY put one up this season on Griz Vision. If we keep asking them about a decimal reader on Griz Vision, maybe they'll want to put one up too.

If you are gonna do it.....do it right. They won't if they do...they will go with a cheap app for a phone and call it close enough.

"I have a 1khz precision calibrator to properly set your baseline. It has an one external mic input as well as the standard built in mic. The display is digital or analog and I can measure SPL within +/- .5db"

Now I'm curious. Why (do you have this gadget?) Work or video.....? Just for kicks? I have some cool things but nothing that cool.
