Mind control: Military and intelligence planners have been exploiting it for decades 


Auditory Effects

The military interest in auditory effects was present since the first inventions were patented, but in 1971 came a system which would allow troops to communicate through a radio transmitter which would render the enemy deaf and disoriented while allowing “friendly” combatants to communicate at the same time.

The device is described as follows:

“Broadly, this disclosure is directed to a system for producing aural and psychological disturbances and partial deafness of the enemy during combat situations. Essentially, a high directional beam is radiated from a plurality of distinct transducers and is modulated by a noise, code, or speech beat signal. The invention may utilize various forms and may include movable radiators mounted on a vehicle and oriented to converge at a desired point, independently positioned vehicles with a common frequency modulator, or means employed to modulate the acoustical beam with respect to a fixed frequency.

During combat, friendly forces would be equipped with a reference generator to provide aural demodulation of the projected signal, thereby yielding an intelligible beat signal while enemy personnel would be rendered partially deaf by the projected signal as well as being unable to perceive any intelligence transmitted in the form of a modulated beat signal.”29

What this says simply is that at-a-distance personal communication could be achieved by one’s own forces while denying it to others and disabling adversaries at the same time.


In 1974, it was noted that using a microwave a signal was changed (transduced) by the receiver into an acoustic signal. This signal was “heard” inside or just behind the head. The report stated:

“…it was noticed that the apparent locus of the ’sound’ moved from the observer’s head to the absorber. That is, the absorber acted as a transducer from microwave energy to an acoustic signal. This observation, to the best of our knowledge, has not been described in the literature and may serve as a mechanism mediating the ’hearing’ of pulsed microwave signals.”31

By 1989, the science took another leap forward with the combination of the modulated signal on a microwave carrier. This provided a much more efficient delivery of the sound. It was reported:

“Sound is induced in the head of a person by radiating the head with microwaves in the range of 100 megahertz to 10,000 megahertz that are modulated with a particular waveform. The waveform consists of frequency modulated bursts. Each burst is made up of ten to twenty uniformly spaced pulses grouped tightly together. The burst width is between 500 nanoseconds and 100 microseconds. The pulse width is in the range of 10 nanoseconds to 1 microsecond. The bursts are frequency modulated by the audio input to create the sensation of hearing in the person whose head is irradiated.”31

Two other patents awarded that year addressed this breakthrough. The first invention related to devices for aiding hearing in mammals:

“The invention is based upon perception of sounds which is experienced in the brain when the brain is subjected to certain microwave radiation signals.”32

The second invention confirmed the earlier observations:

Sound is induced in the head of a person by radiating the head with microwaves in the range of 100 megahertz to 10,000 megahertz that are modulated with a particular waveform. The waveform consists of frequency modulated bursts. Each burst is made up of ten to twenty uniformly spaced pulses grouped tightly together.”33

In 1992, another patent was issued with the following description:

“A silent communications system in which nonaural carriers, in the very low or very high audio frequency range or in the adjacent ultrasonic frequency spectrum, are amplitude or frequency modulated with the desired intelligence and propagated acoustically or vibrationally, for inducement into the brain, typically through the use of loudspeakers, earphones or piezoelectric transducers.”34

This device had limited practicality in that it required the person to be in contact with or in close proximity to the sending device. When examined together, each of these patents is seen to be a discrete step toward a new weapon system.

In 1995, it was reported that in the early research, clear sound signals had been sent and received. It is difficult now to determine what level of military or other research was being advanced in these areas. The history is clear from congressional reports that this entire area was of great interest to the intelligence communities. According to Scientists for Global Responsibility:

“Drs Alan Frey and Joseph Sharp conducted related research. Sharp himself took part in these experiments and reported that he heard and understood words transmitted in pulse-microwave analogs of the speaker’s sound vibrations. Commenting on these studies, Dr Robert Becker, twice nominated for the Nobel Peace Prize, observed that such a device has obvious applications in covert operations designed to drive a target crazy with voices, or deliver undetectable instructions to a potential assassin.”35

Then, in 1996 came another development, a…

“wireless communication system undetectable by radio frequency methods for converting audio signals, including human voice, to electronic signals in the ultrasonic frequency range, transmitting the ultrasonic signal by means of acoustic pressure waves across a carrier medium, including gases, liquids, or solids, and reconverting the ultrasonic acoustical pressure waves back to the original audio signal”.36

Although this was meant to be used with both receiving and sending hardware, what was determined were the modulation methods for transferring the signal.

The real work was yet to be made public in the form of patents. However, the military claims in the area were starting to surface. What was known from experience was that patents were being held back by the government and confiscated by the military. When this intellectual property was seized, the inventors were given a choice: work for the government, or you cannot continue research or even talk about your invention under a national security order. Those who did not cooperate could have their work effectively shut down.
