Sound wave technology is advancing

in #technology5 years ago

Sound technology has been improving at a fast rate over the last few years. Two engineering students at George Mason University have developed a fire extinguisher that transmits a donut of low-frequency sound waves that, when aimed at a fire, can immediately snuff it. They had hypothesized that high-frequency waves would be useful for extinguishing fire, but actually found that it was low-frequency, bass tones of sound that worked in this way.

Researchers at Duke University have developed a plastic device that can “cloak” sound, by diverting the waves away from anything on which the device is mounted. It's a pyramid of layers of perforated plastic that alter the trajectory of sound waves as they hit the device. Instead of reflecting those waves out, it allows the waves to continue on the same linear path as if they'd never struck the object.

But a NASA sound wave device is the most intriguing. It uses sound waves to levitate objects. The waves are generated by two devices facing one another, and the interaction of a series of colliding waves causes acoustic and gravitational forces to cancel each other out. Object can then “float” in these colliding waves. One potential use for the device is mixing liquids together in a containerless environment, thus preventing contamination. Another would be in transporting delicate and fragile objects, including biological cells. The technology uses high-frequency sound waves out of the range of human hearing.

But is all this sonic technology really new? Researcher Dr. Carmen Boulter, a professor at the Universisty of Calgary, wonders if the stone building blocks of the great pyramids in Egypt might have been cut with sound waves thousands of years ago. She suggests the ancients might have possessed crystal oscillator technology, utilizing quartz crystals that vibrate at certain frequencies, on a much larger scale than we use them today, in order to achieve their precision cuts.

Boulter claims sound technology was also used in ancient healing “hospitals” in the area of Dahshur. A local there describes the House of the Spirit possessing a system of acoustic chambers that allowed doctors of the time to diagnose and heal with sound. Boulter further suggests that the pyramids had harmonic structures, fields of harmonic resonance, that were designed to replicate the harmonic cavities of the human body. Such sound healing techniques would restore the correct harmonic within the body of a person who was ill.

The big question is, could sound technology help to explain how the pyramids were actually built? Did the ancients possess a knowledge and technology involving sound waves that could levitate the enormous stones used to build the pyramids? Please give me your thoughts in the comments.


Somewhere last year, I started singing when working on proples's backs. And the way it goes seems to be changing with time. Since it started as low humming, and right now it is very close to tibetan Gyuke throat singing. And it really does work for healing. My best result was adding 4 cm lost in the curvature of the spine for a girl who was 194 cm before.
What I really want to know is how it works. Because otherwise all I can say is "magic", and that doesn't seem to cut it (at least for me). So I am greatly interested in those studies.

As for using sound to levitate stuff, I heard the accounts of buddhist monks using huge tubes to amplify sound and moce big stone blocks for construction. Wasn't sure what to think of those stories, since I've never saw it myself.

That is fascinating! Even in the bible, the story of the wall of Jericho claims that it was broken with sound. I personally believe in the power of singing (the bible is always exhorting people to sing) but like you, I want to know the mechanics behind it, even if those mechanics are based in faith. But I think faith-based things interact with the physical world. My first guess is that sound also affects change on the quantum level, but that's just a guess.

Well, the faith is a great tool. Thing is I come from a pre organised religion tradition, and a lot of information on how to do things for best results comes from the ancestors. And while there is a faith element, a lot of stuff seems to be quite direct, without much faith being involved. If the things continue going this way we'll end up in Shadowrun, lol. :->

Once I finish going around and taking pictures I'll write a post on it. It is somewhat inconvenient, because there is a big source of stuff that I could photo is right next to me, but they don't want any publicity, so I can't take pictures.

There is a possibility I'll be able to use ones that were taken in Mongolia, and even videos, because there is a treasure trove of unique stuff. And while I was unable to go, but that is perhaps for the best. I was very underequipped for Mongolian nights, which are very harsh even in the middle of summer. At least in the northern Mongolia.

Interesting post! Thanks for sharing these sound innovations.

Steem on,

Thank you. And, you're welcome!

@daoine-sidhe Would you have any links/references/sources available for the material you wrote about here. I am particularly interested in the House of the Spirit sound healing hospitals in Dahshur.
If you read my NDE post you will see why I have a particular interest in this. Cymatics has already proven that water, fire, and solids can all be manipulated, altered, and/or "moved" through the application of specific sound frequencies. I believe it is just a matter of scaling this to achieve "walls of Jericho" type spectacles.
