That makes sense, I can't really see what it would gain, all you got to do is make up a story about spying and deport the embassy staff.

From Frey's second paper https://www.physiology.org/doi/pdf/10.1152/jappl.1962.17.4.689 the abstract says that peak power density is a critical factor, typically 275mW/cm2 with the average power density being < 1mW/cm2.  So, in Frey's first paper he was quoting average power density. 275mW/cm2 is 2.75kW/m2, don't think I'm going to try this out any time soon.

The ultrasonics idea is real.  It has been proposed and tested as a way to "beam" audio to individuals in a crowd and works through intermodulation at or near the target.  Given the power levels involved, I always thought of it as a dumb idea and safety hazard.
coppercone2:
No I mean the whole plausibility of attacking a embassy in poor ass Cuba with high end secret weapons for no discernible reason other then to irritate a few spies and risk a serious international incident that would probably result in heavy handed trade sanctions, confiscation of top secret equipment and people being kidnapped and threatened. It's like starting a mafia war no one wants to do it. I could see it in the 1960's maybe, when there were a ton of wars (with no predictable outcome) going on in South America and they wanted to put nuclear missiles in Cuba. With submarines the weight of nearby missile threats is much less so its not as crazy for now.

But how would you do this? Put it in a van and risk it getting stopped or investigated? Putting heavy equipment in a nearby building that can get easily broken into and investigated? There would probably be very easy to see suspicious signs of weird sonic transmitters. I mean what are you gonna do, have every traffic cop in the city on your payroll?



There is not many places you can put it on. A boat, in a building or a risky van. I am pretty sure someone in those apartments would complain. I guess you can have a comical submarine that raises a transmitter. The guards at the front post are gonna be eyeballing big vehicles real heavy.

This is what you got there:


So you can either use a boat/sub, do drive bys, rent an apartment, hide something in the government memorial or use the unknown building (Can't figure out what that thing is)

The apartments are just stupid to use because counterintelligence can rent a nearby one or figure out that its being watched/locked out for some reason and they probably already monitor it, and its really easy to break into residential housing or at least loiter nearby.

drive bys - risk getting stopped by traffic cop or having the CIA crash into you with a dump truck to cut your terror van in half. good luck proving its not just a intoxicated construction worker. Everyone including your mother thinks vans are mega suspicious

hide it in public place/memorial - seriously doubtful

submarine/boat - sounds insane

unknown building -anyone know what it is?

use some kind of robot to attach itself to building - also crazy and it can get captured really easily if spotted

I don't know the range on such things, I guess maybe you can also put it in a far away area that has line of sight if its really focused but the reflector would probably be obvious, or maybe a helicopter or drone

maybe you can hide it in the sewer and use the buildings pipes or have ssome kinda antenna pop out of a man hole, if that area even has sewers, when no one is looking  :-DD
coppercone2:
lol maybe its a computer virus that is making various power circuits in the building make acoustic noise by modulation, that might make someone think they are experiencing psychotic symptoms of schizophrenia, or some kind of impedance modulation of the mains to make things hum? can you do something like that? perhaps just connect a audio generator to the mains so you can make the transformers tell people to take off their shoes?

but why? there is also a joke that can be made about government employees but I feel a bit bad
JimRemington:
No excuse for not testing for microwaves, all you need is a hand held broad band sensor.

Here is my version detecting the leakage from a properly operating microwave oven. Cost me about $0.65 for the microwave diode.
