Audio as a weapon


I would like to deviate a bit from the normal audio equipment conversation and delve into the phenomenon of the recent audio "weapon" that appears to have been deployed in Cuba upon State Department employees and now, it appears, in China. I know that very low frequency can be dreadful to listen to but anyone out there have any ideas with regard to how audio could be used as a weapon? It is not my intention to draw speculation of a political nature, I am only interested in the technical aspect of audio as a "weapon". Anyone have any thoughts?

Hey, win some, lose some. The Navy’s program to make a weapon out of a Frisbee didn’t work out either. I guess that’s the breaks. 
All you need is a cannon to fire the bowling balls and slits big enough for them to pass through. It’s not rocket science. 🚀 it’s really more of a thought experiment. Yeah, I know, ouch, right? Besides, you actually don’t even have to do the experiment at all. All you have to do is understand the original Double Slit experiment, what it means and it’s implications.
You might have a point. All photons and actually all atomic particles and all non atomic objects, even bowling balls, behave like particles and waves, e.g., Double Slit Experiment. Whether that’s the same thing as saying particles exist in vibrating particle fields, or whether that’s the same as saying mass is really energy I’ll leave that to the student.

@geoffkait , thank you once again for taking a interest in what I have to say. Matter is made of particles and particles are a vibration of a field, caries mass, and takes up space. Energy is the capacity to cause change and carries no mass and has capacity to do work when produced by matter. Realivistic mass or total energy is not the equivalent of rest mass, that is the inertial mass of object at rest, which is what you are stating. No new pseudo-physics are being claimed by my post...

>>>Actually, I’m not (rpt not) claiming/stating relativistic mass or total energy is equivalent to rest mass. What I said was, according to the famous Einstein equation, energy and mass are related by E=mc2, so one can CALCULATE the equivalent Energy of a given Mass. But that does not (rpt not) mean mass is the same thing as energy. And just because a mass vibrates at some frequency doesn’t alter the fact that it’s mass. It doesn’t mean the mass is energy.

Mass CAN be converted to energy using fusion or fission, obviously, or by burning. Mass is not just another form of energy. Also, I didn’t really say pseudo-physics, but point well taken. 😀 A black hole is purely mass, sometimes 3 billion solar masses of mass. But there is no energy, only mass, spin and electrical charge, which is probably zero. And gravity is a consequence of mass, not energy. The gravity waves detected a couple years ago, the so called ripples in spacetime, were produced by mass, not energy.
So, you’re saying the standard definition of matter is wrong? Is this some new physics? 😳

noun
1.
physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.

Well constructed logic can look like poetry.

But, more importantly, I managed to park Geoff’s mouth.

Do I get some sort of Agon Kewpie Doll award for that?

What I can bestow on you is the Laughing Goat award.

From the men who stare at goats.

No goats, no glory. 🐐

Absolutely, quantum physics is showing that everything in the universe is energy, so on the sub-atomic level we do not find matter we find only energy. This pure energy or light is everything comprised in universe and is resonating at a different speeds. Everything you see or touch is vibrating at one frequency or another including yourself.

>>>>Whoa! Dude! Not sure I go along with your detective work. Sub atomic particles actually do have mass. Now there is such a thing as mass-energy equivalency but that’s not what you just said. Besides light can only travel at one constant speed. The speed of light, which is the constant in the famous equation relating E to m. The units of energy are entirely different than the units of mass. The black hole in the center of the Milky Way is pure dead mass, 3 Million Solar Masses to be exact. You can convert mass to energy, for example burning a log of wood and coverting it to heat, radiant light and ashes (different form of mass).

BTW, I believe that during WWII a writer at Audio magazine suggested using sound waves to detect submarines, which was actually a highly classified secret at the time.

>>>Wow, I didn’t realize Audio magazine went all the way back to WWII. 🙄

How about Sonar? Would that work? I saw that in Run Silent Run Deep. I used to be in boomers.


Can I assure everyone it was not (rpt not) a Teleportation Tweak gone awry or a miscalculated trajectory? Or some bizarre hiccup in the space time continuum. At least I don’t think it was.
