=========================================================================== VI. ULTRASOUND AND VOICE-FM Ultrasound is vibration of the air, a liquid, or a solid, above the upper limit of human hearing which is roughly 15,000 Hz in adults. Voice-FM uses a tone at or near that upper limit, and the speaker's voice VARIES the frequency slightly. Either a "tinnitus-like sound" or nothing is heard by the target. Ultrasound/voice-FM can be transmitted in these ways: - directly through the air using "air type transducers" - directly to the brain using a modulated microwave pulse train - through the air by piggybacking an ultrasound message on top of commercial radio or television The use of commercial radio or television requires that the input signal at the transmitter be relatively powerful, since radio and TV receivers are not designed to pass on ultrasound messages. However, the average radio and TV receiver does not simply stop ultrasound, rather, the ability to pass ultrasound messages "rolls off", i.e. degrades, as the frequency is increased. Today's radios and TVs can carry enough ultrasound messaging to be "heard" by the human brain (though not the ear) to be effective in conveying hypnosis. This was proven by the U.S. military forces in the Gulf War. Ultrasound's (and voice-FM's) main advantage in mind control work is that it can carry VERBAL hypnosis, more potent than simple biorhythm entrain- ment. The brain CAN "hear" and understand this "inaudible voice", while the ear cannot. Once you can convey hypnotic suggestion which cannot be consciously heard, you have eliminated a major barrier to the subject's acceptance of the words being transmitted. In previous decades, "subliminal advertising" using voice and images at normal frequencies were "time sliced" into an apparently normal radio or TV broadcast. This apparently did not work well, and now voice-FM "subliminal learning tapes" commercially available have superseded the time slice method. -15-
