Assuming that our military has already experimented with audio/sound wave technology as a weapon, I wonder what the smallest size this can be made as well as focal point control possibilities… you saw Ironman right? It may well be a more effective weapon as a harmonic disruptor based on the general ‘harmony’ of the human body and instead of neutralizing the ‘noise’ apply a malignant state causing great homeostatic chaos. Sorry I went way off on a tangent there…

Yeah I’m pretty sure it’s because most bands don’t have 10 million dollars lying around. Just sayin.

You need to learn how to use math.

150 decibels to 165 decibels isn’t 5x the power. Each 3db doubles the power, as you yourself state. So 153 is double 150, 156 is quadruple, 159 is 8x, 162 is 16x and 165 is 32x.

On the dB scale , a sound that is twice as powerful as another sound is 3dB louder.

No. A sound that is twice as powerful as another is 10dB louder. You already linked to the Wikipedia article. Thank you.

We have 2 WAS3000′s in each of our 2 acoustic chambers. The smaller chamber has a logarithmic horn with an 8′ diameter mouth in the floor and another in the ceiling. The rooms a 14′ diameter cylinder by 25′ tall. We put spacecraft or spacecraft components in there, then blow nitrogen at 10 to 40 psi through the WAS’s while feeding a computer controlled random noise signal through it to simulate the noise environment of liftoff. The result is 60000′ watts of rocket in your building. The noise signal is 20 to 10000 Hz up to 160 dB overall sound pressure level. The other chamber has similar horns with about 15′ mouths about 40 x 40 x 60 high designed to take a full shuttle payload for acoustic test. The WAS itself has about a 4″ opening at each end. The actual cylindrical acoustic voice coil/acoustic driver is 2 slotted cylinders one with a machined spring to return it to center. The machining is extremely intricate especially for something designed in the early 1970′s. Running these tests is exciting and fun but dangerous. Lots of safety rules

Sound like that would probably shake your eyeballs out!
