A team of scientists from Cal Tech have invented a device for firing extremely destructive & powerful 'sound bullets', high amplitude acoustic
pulses of sound.
What is it? How does it work?
It makes use of a Newton's Cradle type device that is modified to produce a higher intensity
compression wave that is collected & concentrated in a new design of acoustic lens that takes the sound wave being fed into it, and focus's it to an
extremely precise point several inches away.
This in turn multiplies the sound waves amplitude by 100 times more than ever possible before; not 100 times its base value, 100 times the
best result they had ever achieved before.
If you read the 'lets get nonlinear' section
It gives an in depth explanation of how it all works.
Part of the reason this acoustic lens is producing these extraordinary results is due to the meta-materials being used. These are the same
materials being used to make invisibility technologies.
I'm NOT talking about this clever piece of tech making use of optical camera's and
*A functional invisibility cloak has been created by European scientists.
*The invisibility cloak was minute, measuring 100 microns by 30 microns.
*Recreating the invisibility cloak on a larger scale could prove challenging technically.
Meta-materials: The Next Photonics Revolution
So this Meta-Material stuff is some pretty wild innovation & looks to be going to change the world dramatically if given the opportunity. But back to
the sound bullet tech specifically -
What is it capable of?
the acoustic/kinetic energy wave produced can be scaled to a vast range of physical sizes, velocities and Frequencies, for a wide range of uses.
If the sound bullets fired were within the audible bandwidth of human hearing -
The sound waves Daraio and Spadonia manipulated were too high pitched for human ears to detect. Properly adapted to audible sound, the new
meta-material could turn a normal sentence into a split second ear drum rupturing explosion.
scaled up it could be used against submarines -
sound bullets have been described as able to punch a hole right through the sub, or simply melt the entire sub.
I interpreted this as being due to whether a bullet/wave being used to engulf the sub entirely or target a part of it.
scaled down it could be used to destroy tumors by concentrating heat on malignant tissue below the skin without any damage to surrounding tissue
(Likewise, they could scale that one up & use it to simply heat tissue & kill people. but of course they don't mention that...)
Powerful & tightly focused waves could be used to destroy kidney stones, again without surrounding tissue damage
apparently a doctor could use it to 'image' a patients body as they do with ultrasound transducers (transducer means speaker, like on your
stereo) but without high doses of radiation
structural engineers can use it as a surveying tool on bridges & the like
as sound is able to travel through virtually every medium -
air, water, solid matter, you name it and the destructive capabilities have been epitomized in the following:
If these sound bullets were actual bullets, the meta-material would be like transforming hot lead projectiles into rocket propelled grenades,
all converging on one place at one time. The damage such concentrated waves of pressure could create would be devastating.
Its pretty obvious that when this tech starts being used as weaponry it will be like a wet dream for the warmongers......
so who invented this device?
A group of Scientists & Researchers from the California Institute of Technology including:
Currently however the performance of acoustic devices is limited by their linear operational envelope, which implies relatively inaccurate
focusing and low focal power. Here we show a dramatic focusing effect and the generation of compact acoustic pulses (sound bullets) in solid and fluid
media, with energies orders of magnitude greater than previously achievable.
Here is a video of the concept in action - Stress waves traveling in a nonlinear acoustic lens and sound bullet formation
That's all I know about it so far, after a quick search I saw this had not been mentioned at ATS yet, and I thought definitely needed to be.
I'm feeling pretty negative about this technology, more due to the people in power at the moment, we need a radically more intelligent, functional,
peaceful society before I think we could make proper use of this technology, to me, it is evident in the simple fact that everyone involved seemed to
be focused on the 'sound bullets' potential as a weapon, journalists & inventors alike.
Sound's like a vortex cannon but using sound I find the claims pretty far fetched but then I always do until I see something working.
The BBC Show "Bang Goes The Theory" show did a pretty good vortex cannon and managed to knock down a wall just using the pressure wave (clips should
be on you tube) so I think if this Sound one works it could be pretty impressive.
Of course I could be off on completely the wrong track, sounds cool anyway though.
thanks for posting guys,
its good to know that I'm not the only one interested in this tech & concerned about the proposed applications.
As a musician who studied sound engineering briefly I am fascinated that while my lecturers mentioned things like how a perfectly spherical room would
make the worst recording studio as it would set up standing waves & stuff......in this application, spherical object are helping achieve their goals.
I'm also impressed how they mapped out everything to work out exactly where phase shifting would occur, were relying on that data being correct for
the device to function, and they managed to succeed.
what an awful weapon to inflict on the world if in the wrong hands.
And what deplorable timing, there are plenty of wrong hands around who I'm sure would love to use this thing.
Megiddodiddo, the acoustic psychological weaponry claimed to have been used in iraq, the one that the navy would use to 'beam words right into their
heads', seemed to be a very narrow directional beam they could aim at someone's head and speak through it like a loudspeaker from great distances &
mess with the enemies heads.
I imagine that would have been some kind of continual set of waves rather than a pulse of acoustic sound or kinetic energy, although I imagine that is
how medical ultrasound would work also so I guess it doesn't matter as the device could probably do both pulses & waves/beams/whatever....?
I think the main difference will be in the material construction of the device, and the method by which the sound is amplified and directed.
With your bog standard bodged together vortex cannon the science involved is not that complicated, and the results of the testing of vortex cannon is
With this new technology, the entire fabric of the device from the molecular composition of the materials used, right the way to the way the sounds
are made and amplified appears to have been re invented to the level of being barely recognisable when stood next to vortex systems.
I don't know if you could say its at all the same as a vortex cannon if you read how it (the Caltech device) generates & then concentrates the waves,
and that they a referring to everything in the context of sound, but maybe that's my opinion simply out of ignorance as I am only just finding out
about vortex cannon's now..
The vortex cannon creates "a 200 mile-an-hour cloud"...basically an air blast that can knock stuff over at a
here's a video if anyone else was wondering..
A clip from that Band goes the Theory episode mentioned ealier by Teknikal
Well of course I did mention that the main difference would be in the production/ amplification section of the device. Since the vortex runs on
compressed gas, and the new device works by some bizzare compression wave control involving a newtons cradle.
I read one of the linked pages , and it mentioned the possible medical applications of this technology ... I am impressed by the scope of this device
thats for sure. Apart from any interesting possibilities in the military feild, theres a chance this thing could be used to destroy damaged cells in a
human body... if that ever comes off, it will be one of the greatest medical advances for years !
Flagged and Starred. This is a very well done thread and it covers what I feel to be a very important breakthrough. I wonder if they could employ this
same tech on a much larger scale, I think it would be a great alternative to conventional explosives for excavation and the like.
This sounds an awful lot like the fremen sound gun! (from the movie dune) it uses sound energy to destroy things even people! if you havent seen the
movie i recoment watching the original and newer ones quite relevent to today, "the spice must flow" sort of like "the oil must flow"
Sometimes i feel like i'm on the planet of the apes. We have a way of taking something good,and completely using that thing in a bad way. This
technology was once rumored to have brought down the walls of Jerico in the bible,so its possible it's not so new,maybe just stolen technology,who
knows. The human race needs to get some common sense and try to mature fast before it implodes in on us from our child like curiosity.
this is a scary technology for sure...but how much energy has to be put into this thing to get these amazing results....seems like anymore people are
coming up with inventions and ideas that require huge amounts of energy to get such little effect with no mention at all about what power goes into
the machine just a bunch of talk about the end results....look at the particle accelerator and fusion reactors....how much energy do you think goes
into a microwave oven that heats tritium up to 100000000 degrees for a few seconds of fusion....what a waste...maybe this will be the same way
Thanks, OP- always nice, to know what "the enemy", has in his arsenal. Of course, once things get "hot", WE will be aquiring them, also. ANYTHING
they have, WE will have. Hell, I'm planning on making THEM load my truck, before I leave!
They have sound cannons- we have rail-guns. Gonna be fun!!
Have a FUN Revolution!
