+3db's... double power.. ect..

is there eventually a 'catch'

Ear drum explodes? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif See above. It's 120 dB. You can stand next to the Space Shuttle when it launches at 200 dB, but your ears can only take so much.

Would you think eventually doubling the power would 'hit a wall' in terms of actually getting twice as loud?...because im just thinking about how scientists follow Einstein and say that the speed of light is technically impossible to achieve because the ship would grow infinitely large because as things speed up they grow larger (and the speed of light would mean the ship/object would be infinitely large)...or so the theory goes with Einstein..and it also deals with doubling the energy (like in this situation) to go twice as fast (or twice as loud like in this instance)
So, just thinking about that situation made me wonder if there is eventually something that simply doesn't allow it to be that easy...

Diminishing returns apply to everything //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That's what I was thinking //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

supposedly 194db is the loudest possible on land, but I have read theorys about being louder in space or under water or something, kinda of over my head.

I remember when they said no stereo would reach 150, then nobody would reach 160, and so on. Kind of wierd how hardcore spl guys always prove the experts wrong

Volcanic eruption: 250 dB. They must base that on estimates as the air can only move so much sound, like you said.

they can figure out by measuring from long distances and calculating what it was closer

194.09dB, the point at which sustained sound is next to impossible. Thats when the pressure reaches 1 atmosphere, and if a sine wave is to be sustained, there would need to be negative pressures somehow.

I went from 150ish with 1 amp @ 1ohm to 156 with 2 amps @ .5

So i guess thats like 2.5x the power and i gained 6db

Weird stuff

Sooooo....like 2 BTLs or something?

Yes, it's called power compression.

No.

An object in motion shrinks (Lorentz contraction) in the direction of the motion (to an outside observer). But it's mass increases, meaning it takes more energy to move the object. When you reach close to the speed of light, the mass would become infinite meaning it would take an infinite amount of energy to move the object. The object would also be very thin (to an outside observer).

Time for the object moving near the speed of light would also slow compared to the observer.

Special relativity FTW.
