Since lights can be utilized in the field or in controlled situations and do cause certain behavioral changes in man, this subject will be discussed in detail later in this report. PART E - Sound 1. (Uv) Sound, from one source or another, has been used to elicit behavioral changes in man in every war ever recorded. It may be a simple bugle call or battle cry or a mechanical siren device; but whatever is used there is normally a psychological response by the receiver. Regardless of the absolute level, sounds of enemy weapons with which one is unfamiliar is frightening provided the sounds are associated with a feared weapon or the unknown. + 2. (U) Auditory effects have been and still are researched. Nerve deafness can certainly result from. prolonged exposure to loud sounds. For the purpose of this study it is believed that the nonauditory effects are just as important when discussing behavioral alterations. For example, exposure to a siren~generated sound of 20 kilohertz at 1 watt per square centimeter kills a variety of insect life in three to four minutes and larger animals (mice) in about one minute, Human operators, with earplugs, experience "cool sizzling sensations" in the mouth and an unpleasant tingling in the nasal passages when near the siren. 3. (C/NFD) Sound can be used on controlled groups or in the field. Sound can produce behavioral changes and the effects of sound on humans is being investigated in the Soviet Union. For these reasons, a more detailed discussion can be found later in this report. PART F ~ Electromagnetic Energy 1, (C/NFD) Super-high frequency electromagnetic oscillations (SHF) may have potential use as a technique for altering human behavior. Soviet Union and other foreign literature sources contain over 500 studies devoted to the biological effect of SHF. Lethal and non-lethal. aspects have been shown to exist. In certain non-lethal exposures, definite behavioral changes have occurred. There also appears to be a change in mammals, when exposed to SHF, in the sensitivity to sound, light, and,olfactory stimuli (55). ‘ 18 NO FOREIGN DISSEMINATION CONFIDENTIAL e or Kelease ' - .
