Unconventional Weapons: Sonic Cannon

Hello, I would like to have a discussion and share information about sonic cannons.

Their history, evolution, drawings, current developments (if any)..
any information available will be appreciated.

My present infomation is that this kind of ultra-high-frequency(or)ultra-low-frequency sonic weapon was first developed by the Germans in WWII but never seen much action (a failed-impractical weapon), then the French build it with less-or-more same evolution and symptoms. I also have in my posession the drawings and patent of a compressed air sonic weapon designed by a brilliant greek inventor who sold it to a french radiosonic-laboratory back in the 70's.

I don´t know whether this is what you´re looking for, but a working sonic weapon is the LRAD (Long Range Acoustic Device). It was used for example in 2005 by a cruise ship to fend off a pirate attack near Africa.

Thank you. I didn't know about the LRAD. I guess this is using high frequency directed hypersounds.
I found an entry also in wikipedia:
en.wikipedia.org...

What I was originally talking about is a ultra-low-frequency sonic superweapon (4.3hz or lower).
Its inventor thought about it when electronic instruments in his labaratory caused to him nausea, and stomach problems and some cracks on the walls! He measured the decibels with a device and found that those problems were caused by ultra-low-frequency sounds vibrating the molecules of matter.
So, he then designed a weapon about this phenomenon also inspired by the biblical story of the thick walls of Jeriho destroyed by the Hebrew "trubets" who thought was a prehistoric sonic weapon delivered by some advanced prehistoric civilization.
Here are the schematics of the Greek (G.Giolvas) compressed air chamber ultralowfrequency resonance sonic weapon (4.3Hz):

He then sold it to a french laboratory after finding out that the greek military didn't care much about his invention. (fools)
According to the inventor claims, this device if built in large scale, could cause severe damage even to reinforced concrete buildings!

Here is the french variation of a sonic weapon device dated around 50's and 60's, by Vladimir Gavreau.
Same symptoms and evolution with the greek cannon. Also designed with pipes but in a different pattern.

Finally here is a video of the German sonic weapons of WWII:
(but I don't have much information about them)

AFAIK the Gavreau story is a myth - nobody ever repeated his results. otherwise everyone would have wall-shattering infrasound cannon.

SOCOM are still looking at penetrating infrasound, but all acoustic weapons are very much int he non-lethal range.

Does anyone have any evidence otherwise?

Those unconventional weapons are in the general category of Energy Beam Weapons which are still covered by a veil of secrecy as fas as I know.
I have the registered patent of the Greek sonic cannon design by G.Giolvas (nuclear physcist, mechanologist & inventor) dated in 1970.
It has the designation "secret" all over it, because this patent actually remained a state secret for about a year for close examination by the army.
After the rejection in his country the patent was finally sold to the french laboratory for about 2.5 million drachmas (early 70's). He personally knew the chief scientist of the laboratory in question.
Moreover, around the same time in France, there was a series of popular press articles about the development of a sonic "death ray" capable of disabling tanks, destroy buildings etc.
This raises some serious questions, IMHO.

nothing about a sonic cannon. but i have heard of a improvised munitions gun. it can make rounds out of different material. sands, ice/snow. to compresses the material and is a hard projectile. apperently used for covert ops as no trace like spent cartridge shells.

Maybe 7-8 years ago I had a disc that outlined a weapon called gideon or gideons trumpet that was supposedly designed to penetrate whatever field that surrounds a U.F.O. This line of offense was arrived at because of the 1942 U.F.O. "invasion" of Los Angeles. Thinking that air could pass through these shields, and we all know that thousands of rounds expended that night were futile, an air weapon was in order. Please don't ask me for the disc origin, at the time I didn't think much of it (still don't) just passing it along for you to chew on. BTW The ex got the computer and all else

dont know if it helps but Tom bearden might be a direction to search into,

he´s usualy been about EM weapons and scale use of em , but there might be some thing about sonic and railguns even

if i recall in one of his videos he brefily mentions lazer technologies the size of conventional SMG´s and something eles in that direction , im very sorry i cannot provide a link or such ,

but tom bearden and the silent killers or something like scalar weapons in google video

Ask your favourite search engine about thermoacoustics.

I think the type of weapon you and I are interested in is called the death trumpet. Lower frequencies they make the ground shake and tear buildings apart killing any sizable living thing. While I have designs of making and amplifying the resonance its potency is in directing the waves in phase so they do not disperse. Tesla was building something similar although his initial idea was for it to be wireless energy later he made it into a weapon. I doubt you will find much information on this dooms day machine its reason for existence is to purge the world of race, religion, countries and cultures in the last war for peace.
