Loudest sound in recorded history...

[nourkah 10+ year member]

According to http://www.wikipedia.com the loudest sound in recorded history was the eruption of Krakatoa in 1883.

The following is taken from the text.

"The explosions were so violent that they were heard 2,200 miles (3,500 km) away in Australia and the island of Rodrigues, near Mauritius, 4,800 km away; the sound of Krakatoa's destruction is believed to be the loudest sound in recorded history, reaching levels of 180 dBSPL 100 miles (160 km) away."

I wonder how they measured it.

Do you guys think that my Alpine Type E could get that loud if I had the right setup and amp??? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

that was on an old AC mic though.. it would be about 3000000 on the new TL.

oh and yeah one type E can do about that. installation is everything

If it was really 180 dB one hundred miles away....

Imagine how freggin loud it would have been right next to it! Like InstaDeaf //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

The measurement is an estimate. Every time you double the distance from your source you lose 3 db. They know "about" how loud it was from a given distance, and they have the approx area where the sound no longer heard. They can regress to find the approx value at the source, but it's still an estimate. I know rockets taking off are 200+ at the source. I'd approx. krakatoa at around 250ish.

wow. that is effing loud mang. maybe someone will be able to acheive that level one day in the far future.

roffles.

It would be more of a shockwave than a sound, the primary frequency component would have to be very low to travel as far as it did. Old above ground atomic tests could give a good baseline on how they might estimate a DB level.

Dude when I took a dump and it hit the water it was earth shattering.

Krakatoa doesn't have shit on me.

i think it's vice versa //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

I'm sure there's some way to figure out how loud it was by figuring out how far away it was heard.

yeah, 180bd at a fairly low frequency wouldn't seem super loud, it's certainly shake things up a bit though.

Eh.

lol.

yeah, I don't reckon it would have been 180dBs 100miles away... people at that distance would have probably been killed from that sort of sound pressure, so, how can they estimate that?

Maybe people were killed then......could be a factor to how they got the estimate.

One time I farted so loud, it could be heard in california.

Oh wait ...

I was in cali when I farted //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
