There is a great deal more information on microwave hearing (the
Frey
effect) on the web now than there was even just a couple of years ago.
At the bottom of this article I have included a list of some of the
quality material now available. I have focused on the
voice-modulation aspect, whereby an audio signal can be modulated onto
the microwave carrier and subsequently perceived as the original sound
"in the head" of a person illuminated with the microwave radiation.
Nonetheless, full answers to questions such as the following -- as far
as I know -- are not known in the open literature:
-- Do individuals vary widely in their sensitivity to the effect?
What power levels affect the most sensitive people?
-- How do different variables affect an individual's sensitivity to
the effect? Are there ways it can be increased? Would initial
harassment and resulting PTSD have any effect on it? Chemicals?
Electromagnetic exposure? Age? Etc.
-- How do microwave parameters (such as pulse rate) for peak effect
vary for different people? (Some mathematical models vary according
to head size, as one variable.)
-- What is the subliminal threshold for any effect? Is it below
the conscious hearing level?
-- Are there other low-power effects which can cause subjectively
similar results (such as "voices") in humans?
These sorts of questions are important just for their potential
relevance to the health of people in an environment full of
electropollution.
It would not be that difficult to construct a test of the effect that
people could take like a hearing test. It would just require
some
market for the machine (homemade devices may be dangerous) and a
medical recognition of the effect.
If such devices and practitioners were available, then people
reporting related symptoms could be tested, if only to find out the
relevant data. They could also get an idea of what such voices
sound
like and "seem like" subjectively and compare them to what they
experience.
The effects mind control victims report might be related to the Frey
effect or might not. Specifically, among true victims, some may
be
assaulted with microwave-hearing-based weapons but others are
assaulted with different technology or techniques.
Effects such as microwave hearing might be used at a later stage to
actually dismiss victims, by people claiming it was all electrical
sensitivity or it was all harassment with microwave-hearing-based
devices. But what is new? Mind control victims know it
is always
something with the torturers, always some distraction or
rationalization, anything but that they are victims of domestic
torture operations. Don't forget the known and documented mind
control victims who are still ignored and ridiculed, and secret
research projects like PANDORA set up specifically to test microwave
effects on human behavior. How many domestic torture victims
further
persecuted as "schizophrenics" by supposed healers are too many?
The
Soviets had a term, "sluggish schizophrenia," for people crazy enough
to challenge the totalitarian state.

An innovative and revolutionary technology
is described that offers a
means of low-probability-of-intercept
Radio frequency (RF)
communications. The feasibility of the
concept has been established
using both a low intensity laboratory
system and a high power RF
transmitter. Numerous military applications
exist in areas of search
and rescue, security and special operations.

A decoy and deception concept presently
being considered is to
remotely create the perception of noise
in the heads of personnel by
exposing them to low power, pulsed microwaves.
When people are
illuminated with properly modulated
low power microwaves the sensation
is reported as a buzzing, clicking,
or hissing which seems to
originate (regardless of the person's
position in the field) within or
just behind the head. The phenomena
occurs at average power densities
as low as microwatts per square centimeter
with carrier frequencies
from 0.4 to 3.0 GHz. By proper choice
of pulse characteristics,
intelligible speech may be created.
Before this technique may be
extended and used for military applications,
an understanding of the
basic principles must be developed.
Such an understanding is not only
required to optimize the use of the
concept for camouflage, decoy and
deception operations but is required
to properly assess safety factors
of such microwave exposure.

There is a microwave hearing effect that
occurs at very low power
densities and a skull vibration effect
that occurs when very high energies are
applied to the head. There is
some confusion in the literature because the
vibration effect has often been referred
to as a microwave hearing effect,
but it is not the same phenomena.

Questions Linger About Health Effects Of DOD's 'Non-Lethal' Ray
by Christopher J. Castelli, Chief Editor
[...]
Though U.S. military proponents of the
non-lethal ray say they
worry the public will get the wrong
idea about the technology, the Air
Force's own "New World Vistas" report,
published in the mid 1990s,
actually describes goals of using electromagnetic
radiation for what
sounds like mind control.
"It would also appear possible to create
high fidelity speech in the
human body, raising the possibility
of covert suggestion and
psychological direction. When a high
power microwave pulse in the
gigahertz range strikes the human body,
a very small temperature
perturbation occurs. This is associated
with a sudden expansion of the
slightly heated tissue," states the
report. "This expansion is fast
enough to produce an acoustic wave.
If a pulse stream is used, it
should be possible to create an internal
acoustic field in the 5-15
kilohertz range, which is audible. Thus
it may be possible to 'talk'
to selected adversaries in a fashion
that would be most disturbing to
them." This appears to be a reference
to the "microwave hearing
effect," a scientific phenomena Frey
is credited with discovering in
the 1960s.
Hackett said the non-lethal MMW ray project
is not seeking to create
that kind of talking effect in people's
heads.
In fact, Frey and Hackett said the microwave
hearing effect does not
occur with millimeter waves (which range
from 3 to 300 GHz).
"On the other hand, if your millimeter
waves have enough energy
density, are powerful enough, there
are other phenomena where you
could cause sort of a concussion kind
of effect which could
conceivably be heard by bone conduction.
It would transfer through
skin to bone and bone into the inner
ear," Frey said. He said it might
be possible to modulate such energy
to create the perception of some
intelligible sounds. "But off hand,
I can't tell you what kind of
power levels you might need to do that,"
he said. Hackett dismissed
the idea of transmitting intelligible
sounds to the head with MMWs as
pure speculation.

Selected excerpts to
Biological Effects of Radiofrequenzy
Radiation (revised2.February1996 )
cut/condensed from Biological Effects
of Radiofrequency and Microwave
Radiation: Application, Hazards, and
Safeguards. by Wolfgang
W. Scherer( 25. March 1994 )
..... A special role is played by
the electrophonic effect of microwave
hearing. Humans can perceive a
buzzing or clicking sound in the back
of their heads at exposure to
power densities as low as 0.1 mW/cm²
of pulsed microwave radiation
(200-3000 MHz) , depending on the pulse
repetition frequency and the
peak power density (around 300 mW/cm²).
The absorbed energy produces a
thermoelastic expansion of the brain
tissue causing an acoustic
pressure wave which is detected in the
cochlea by the hair cells of
the organ of Corti. The energy needed
to produce this effect is so
small that it does not actually increase
the mean temperature of the
brain, yet the acoustic sensation is
strong enough to be clearly
perceived in an ambient noise level
of circa 65 dB. Due to this fact
microwave hearing does not cause an
apparent physical reaction within
the head, but it is well known that
humans suffer general stress
reactions when they are exposed to higher
levels of sound. Noise
cannot only be an annoyance, but when
it consists of pulsed sounds it
affects heart beat and metabolic rates.
[8] The subliminal aspects of
noise levels are here not even considered
despite the recognized
physiological effects of acoustic noise.
It would be a very
interesting field for research to probe
the subliminal acoustic
effects of such exposure to low radio
frequency radiation. A possible
link between such radiation and noise
related reactions , effects, or
damages would be an aspect worth of
further investigation......

Relatively high-intensity RF fields have
been shown to cause adverse
health consequences by heating tissues.
No adverse health effects have
been scientifically confirmed from exposure
to low-level RF fields for
extended periods, but certain questions
have not been thoroughly
studied. There is very little information
available in the scientific
literature to assess any health risks
from exposure to pulsed RF
fields. Studies are needed that seek
to identify any biological
effects produced by pulsed RF fields,
of both high and low peak pulse
intensities. Examples of current and
future technologies using pulsed
RF fields are telecommunications, civilian
and military radar systems,
including emerging radar technology
such as ultra-wide band radars and
anti-electronic weapons. Current and
future research applicable to
mobile telephone systems should focus
on the 900-2000 MHz frequency
range and appropriate pulsing and modulation
patterns.

By radiating themselves with these "voice
modulated" microwaves, Sharp
and Grove were readily able to hear,
identify, and distinguish among
the 9 words. The sounds heard were not
unlike those emitted by persons
with artificial larynxes. Communication
of more complex words and of
sentences was not attempted because
the averaged densities of energy
required to transmit longer messages
would approach the current 10
mW/cm2 limit of safe exposure.
