What is the loudest SPL EVER recorded????????????????????????

240 in h2o apparently the navy wanted to do this?

What amps were they running?

i thought i remembered hearing somewhere that the loudest recorded noise ever was that of a blue whale, and it hit the mic at something like 220 Db underwater, and it was well above the human range of hearing. i could be mistaken, but i think that whales(and possibly other marine animals) routinly create ultra high intensity signals like this, and they dont pose a threat to humans since the freq's are so high they cant afect us... i could be mistaken though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

A shuttle launch is around 240 i believe. The only reason it can get this high is because of the extreme heat that it puts out, it changes the physics of the air around it a little and makes it more compressable.

I bet their is not really a limit, all it is is expansion and contraction, really high frequincys are easier to make louder Dbs caus they are really short bursts of compression and contraction, (contraction, I don't know, decrompression) so maybe in our hearing rang their is a limit. But I dunno thats just what I think.

LOUD.....even if we couldnt hear a sound cuz it was above are hearing. wouldnt we still fell the pressure?(spl)

Its not 240. Im positive.

Its the blue whales, yes. It's 186 db. A girl in my class did a report on a blue whale and that was the only part I remember //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

oh 240? i highly highly doubt that. maybe underwater. perhaps if we launched our rockets from the sea-floor it could reach 240 dbs but i highly doubt it.

Didn't Scottie Johnson break 180db with the Pioneer SPL truck??

it's Scott Owens not Scottie Johnson...

rarefaction is the correct term, not decompression.

didnt Crackatoea (i know the spelling is wayyy off but its that super volcano that blew up in the 1800's and blew up the whole island)

make the loudest sound ever recorded when it errupted

Does this mean Scot, Alan Dante and Mike can talk to whales with their vehicles ??

 

[J3M Concepts 10+ year member]

185.1 in a vehicle is the loudest I know of...legal or not I dont know...on an Audiocontrol so that ~180 on a TL..but Scottie Owens i think has done a 183 on the TL

heres the video via:ROE http://realmofexcursion.com/videos/Competitions/southamerica.1.wmv

at 190 something in Earth's atmosphere the soundwave turns into a shockwave
