Microwave hearing is a phenomenon,decribed by human observers as the sensations of buzzing,ticking,hissing,or knocking sounds that orginate within or immediately behind the head. There is no sound propagating through the air like normal sound This technology in its crudest form could be used to distract individuals,refined it could be used to communicate with hostages or hostages takers directly BY MORSE CODE or other message systems, possibly even by voice communication.
A 1998 US Dept of the Army unclassified document. It became unclassified in 2006. Document is an ADDENDUM to the Nonlethal Technologies-Worldwide study (NGIC-1147-101-98) http://www.slavery.org.uk/Bioeffects_of_Selected_Non-Lethal_Weapons.pdf THERMOELASTIC EXPANSION STUDY OF OUR COCHLEAR MECHANISM OF HEARING AND MICROWAVE HEARING OF RF PULSED FIELDS technology goes back over 30 years Mechanism to Produce the Desired Effects After the phenomenon was discovered,several mechanisms were suggested to explain the hearing of pulsed RF fields. Thermoelastic expansion with the brain in response to RF pulses was first studied and demonstrated in inert materials and was proposed as the mechanism of hearing of pulsed RF fields. A PRESSURE WAVE IS GENERATED IN MOST SOLID AND LIQUID MATERIALS BY A PULSE OF RF ENERGY a pressure wave that is several orders of magnitude larger in amplitude from that resulting from radiation pressure or from electrostrictive forces. The characteristics of the field-induced cochlear MICROPHONIC IN guinea pigs and cats, the relationship of pulse duration and threshold, physical measurements in water and in tissue simulating materials,as well as numerous theoretical calculations ALL POINT TO THERMOELASTIC EXPANSION AS THE MECHANISM OF THE HEARING PHENOMENON. Scientists have determined the threshold energy level for human observers exposed to pulsed 2450 MHz fields (0.5 to 32 micron pulse widths). They found regardless of the peak of the power density and the pulse-width, the per pulse threshold for a normal subject is near 20 mJ/kg. The average elevation of the brain temperature associated with a just perceptible was estimated to be about 5xl0 -60 C, (0 drops lower than the 6). Time to Onset The physical nature of this thermoelastic expansion DICTATES AS THE SOUNDS ARE HEARD AS THE INDIVIDUAL PULSES ARE ABSORBED. THUS THE EFFECT IS IMMEDIATE (WITHIN MILLISECONDS) Tunability The phenomenon is tunable in that the characteristic sounds and intensities of those sounds depend on the characteristics of the RF energy as delivered. Because the frequency of the sound is dependent on the pulse characteristics of the RF energy, IT SEEMS POSSIBLE THAT THIS TECHNOLOGY COULD BE DEVELOPED to the point where words could be transmitted to be HEARD LIKE THE SPOKEN WORD EXCEPT THAT IT COULD ONLY BE HEARD WITHIN A PERSON'S HEAD. In one experiment, communication of the words from one to ten using "SPEECH MODULATED" MICROWAVE ENERGY WAS SUCCESSFULLY DEMONSTRATED. MICROPHONES NEXT TO THE PERSON EXPERIENCING THE VOICE COULD NOT PICK UP THE SOUND. ADDITIONAL DEVELOPMENT OF THIS WOULD OPEN UP A WIDE RANGE OF POSSIBILITIES. HUMANS HAVE BEEN SUBJECTED TO THIS PHENOMENON FOR MANY YEARS Technology Status of Generator/Aiming Device This technology requires no EXTRAPOLATION to estimate its usefulness. Microwave energy can be applied at a distance, and the appropriate technology can be adapted from existing RADAR UNITS. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hum Sufferers" group.
