The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks induced by pulsed/modulated microwave
frequencies. The clicks are generated directly inside the human head
without the need of any receiving electronic device. The effect was
first reported by persons working in the vicinity of radar transponders during World War II.
These induced sounds are not audible to other people nearby. The
microwave auditory effect was later discovered to be inducible with
shorter-wavelength portions of the electromagnetic spectrum. During the Cold War era, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish (Journal of Applied Physiology,
Vol. 17, pages 689–692, 1962) information on the nature of the
microwave auditory effect; this effect is therefore also known as the
Frey effect.
Dr. Don R. Justesen published "Microwaves and Behavior" in The American Psychologist (Volume 30, March 1975, Number 3).
Research by NASA in the 1970s[citation needed] showed that this effect occurs as a result of thermal expansion of parts of the human ear around the cochlea,
even at low power density. Later, signal modulation was found to
produce sounds or words that appeared to originate intracranially. It
was studied for its possible use in communications. Both the US and USSR studied its use in non-lethal weaponry.[citation needed]
Pulsed microwave radiation can be heard by some workers; the
irradiated personnel perceive auditory sensations of clicking or
buzzing. The cause is thought to be thermoelastic expansion of portions
of auditory apparatus.[1]
The auditory system response occurs at least from 200 MHz to at least 3
GHz. In the tests, repetition rate of 50 Hz was used, with pulse width
between 10–70 microseconds. The perceived loudness was found to be
linked to the peak power density instead of average power density. At
1.245 GHz, the peak power density for perception was below 80 mW/cm2. The generally accepted mechanism is rapid (but minuscule, in the range of 10−5 °C) heating of brain by each pulse, and the resulting pressure wave traveling through skull to cochlea.[2]
The existence of non-lethal weaponry that exploits the microwave auditory effect appears to have been classified "Secret NOFORN" in the USA from (at the latest) 1998, until the declassification on 6 December 2006 of "Bioeffects of Selected Non-Lethal Weaponry" in response to a FOIA
request. Application of the microwave hearing technology could
facilitate a private message transmission. Quoting from the above
source, "Microwave hearing may be useful to provide a disruptive
condition to a person not aware of the technology. Not only might it be
disruptive to the sense of hearing, it could be psychologically
devastating if one suddenly heard "voices within one's head".
The technology gained further public attention when a company
announced in early 2008 that they were close to fielding a device called
MEDUSA (Mob Excess Deterrent Using Silent Audio) based on the principle.[3]
