Acoustic levitation

Post Reply New Topic

So I was reading about Tibetan monks supposedly moving stone slabs using resonating frequencies in their voices,drums, and giant bowls, and somehow lifting stone slabs and arcing them to land in a pre-calculated area.
sounds very hard to believe to me. But being an optimist , I accept the possibility that they may have in fact had such knowledge. just saying, if the Egyptians built the pyramids, and to this day nobody is really sure of how, I think this may be one overlooked possibility by mainstream science.

although my source for the tibetan levitation is a crappy ufo conspiracy site, I think there may be some proof to this story,
I love discussing such things, because one day I would like to reproduce the effects for my own intentions whatever they may be(probably inventing) anyways, don't bash me im not a conspiracy nut, just someone who likes science.

oh btw here is my link to my source
http://www.crystalinks.com/levitationtibet.html

another cheesy site, but this one has a description with diagrams.

I don't think Crystalinks is crappy at all. There's some great stuff on there.

I've never seen acoustic levitation in effect, but who knows.

ok reputation aside. being the type of person I am, I crave knowledge of things that have to do with movement. more specifically flight. you think it would work to experiment with a 15w amp and guitar. experiment with tuning the low E-string to the resonant frequency of something like a foam cup.

man, I bet im going to drive my college professors crazy with all my questions.

You might be able to move pebbles that way.

Sound waves in air dissipate rapidly so it sound waves are not a particularly efficient way of transporting energy.

not saying your wrong, but the same thing was said about 'Heavier than air' flying machines being impossible.
I wanna get the mythbusters to test this somehow.

This seems really interesting,

The dissipation of energy in air is an experimental fact. The skepticism concerning heavier than air machines (Lord Kelvin's view) had to do with engines and motors. There was no doubt that heavier than air flying objects exists (birds, insects and bats). The question was about motors. At the end of the 19th century the weight of internal combustion engines was too great to make a mechanical heavier than air flyer that could be powered and directed by a motor. Among the great inventions of the Wright Brothers was a 12 hp engine with a favorable power to weight ratio. The Wright Brothers discovered two great new things: How to turn a flyer with stability (three axis control) and how to power it sufficiently with a small engine.

Now getting back to moving things with sound, even a beamed wave of sound will dissipate rapidly in open air. One needs a closed wave guide.

I wasn't doubting the science, what I meant is, our current understanding of things is and never will be 100% correct.
I know at minimum though, If this experiment were carried out with monks, in a way the diagrams show, the object would move/react. whether or not it would hurl itself needs to be tested. I realize sound dissipates, But we are talking hypothetically about having like 600-800 monks perfectly chanting a certain frequency, and beating drums to another frequency, to match the bowl and the stone. also to take into consideration, the use of an open cliff area. Such an area would echo and naturally amplify all that sound. not saying you could hurl boulders, but im saying I would like to see what happens as opposed to guessing what happens with math.

I'm a visual learner, so 99% of the time, I'm never satisfied unless I can see it.

There is not enough energy in 1000 sets of vocal chords chanting as loud as a human voice can can to levitate a brick. Singing in harmony does not increase the total amount of energy in the sound. What singing in harmony can do is cause a body to resonate releasing what potential energy the resonated body has. That is how bridges (like the Tacoma Narrows Bridge) can be shaken apart. The energy released was potential energy gain by a slight lift produced by the wind blowing across its narrow roadway. In short it was the Bernouli effect that lifted the bridge slightly the bridge drop and it swung then it was picked up a bit by another gust and so on. Yes, an airfoil can "levitate". That is how airplanes fly. The Tacoma Narrows Bridge roadway was lifted by a few feet at most. Even if it were not anchored it could not have flown away.

Incidentally if was the volume of air moving across the deck that was sufficient to give it a little life,

Now the monks singing in tune do not generate that kind of air volume and it is not directed sufficiently to lift anything but a very light airfoil. It isn't harmony that does it. It is volume (amount) of air moved over the airfoil.

I am actually in 99.99% in agreement with you .01%=natural skepticism
you proved your point very well. outta curiosity, did/ what did you study in college?
