Auditory signals generated in humans and animals who are irradiated with short rectangular
pulses of microwave energy have been studied. Assuming that the effect arises from sound
waves generated in the tissues of the head by rapid, thermal expansion caused by …

Nine cats were prepared for the recording of potentials in 3 brain sites evoked by acoustic
and microwave stimuli. Loci in which potentials were observed were eighth cranial nerve,
medial geniculate nucleus and primary auditory cortex. The effect of cochlear disablement …

THE SUBJECT OF MICROWAVE interaction with biological sys-tems is drawing the attention
of many scientists and engineers in life and physical sciences. While microwave radiation
with su~ ficiently high power densities and sufficiently long exposure penods is known to …

… Cochlear microphonics have been recorded from the round window of cats and guinea pigs during
irradiation by pulse-modulated 9 18-MHz microwaves. These results indicated that
microwave-induced auditory sen- sation is mediated by a mechanism of hearing …

When human subjects are irradiated with pulse modulated microwave energy they report the
perception of a sound that appears to originate from within or slightly behind the head. Three
of the possible mechanisms are examined using first order mathematical approximations …

Abstract— The hearing of microwave pulses is a unique
exception to the airborne or bone-conducted s.

… The thermoelastic theory of auditory perception of pulsed microwaves describes the acoustic

One of the most widely observed and accepted biologic effects of low average power
electromagnetic (em) energy is the auditory sensation evoked in man exposed to pulsed
microwaves. le The effect appears as an audible clicking or buzzing sensation that …
