Acoustic Levitation Chamber

Back


This is an acoustic levitation chamber I designed and built in 1987 as a micro-gravity experiment for NASA related subject matter.
The 12 inch cubed plexiglas Helmholtz Resonant Cavity has 3 speakers attached to the cube by aluminium acoustic waveguides.
By applying a continuous resonant(600Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; I was able to control levitation and movement in all 3 (x,y,z) axis of the ambient space.
This research was used to show the effects of micro-gravity conditions that exist in the space shuttle environment in orbit, but done here on Earth in a lab.
This is not "anti-gravity." So don't waste time arguing something pointless.

UFO's with low humming sound? connection?

No, no connection. You're just gullible to even believe UFOs are interstellar alien space craft.

I never said "interstellar alien spacecraft." It's possible but I think the gov. plays a large part in the UFO sightings. at least the ones we see

When most people say "UFO's with low humming sound? connection?" it is entirely reasonable to assume they are implying flying saucers. And that IS what you are implying. You think the saucers are built by the government, that's the only real point of contention you've made. If the government is experimenting with stealth blimps, so what? Whoopdie damn doo. Lots of machines have low humming sounds.

It's completely reasonable to assume a person is talking about aliens when they mention UFO's. I was just stating the possibility that aliens or the government might have manipulated acoustic levitation to make flying vehicles

I've seen these levitaters a few times over the years, too bad they'd be useless in the vacuum of space.

this is how my flying saucer invention works.

you must be aware of haarp then eh?

That's pretty amazing!

I wonder, why does the ping pong ball start spinning? Air currents?

Have you heard about the idea of using a high frequency sound that we could not hear as the carrierr frequency for sounds we could here, its an idea for a new kind of speaker. I forgot what it was called.
