A PSYCHOPHYSICAL STUDY OF THE RF SOUND PHENOMENON

A. Frey, R. Messenger, E. Eichert · 1972

The study investigated the RF sound phenomenon, where humans perceive sound when their head is illuminated with pulsed RF energy. In phase one, a portable RF sound demonstration unit operating at 1.2 GHz was assembled and used to demonstrate the phenomenon. Phase two experiments showed that perceived loudness is a function of peak power density once a minimum pulse width is used, and that pulse repetition rate is the dominant parameter for sound quality. A threshold peak power density of 80 mW/cm² was derived by extending the loudness curve, though not with optimal parameters, and average power density was not particularly meaningful for this phenomenon. Phase three found that vocoder technology and periodicity pitch rules could not generate speech perception via RF sound.

Étude des perturbations biologiques chez les techniciens O.R.T.F. dans certains champs électromagnétiques de haute fréquence

M. DEROCHE · 1971

No progressive diseases linked to the exposure were found. Reversible functional disturbances including fatigue, headaches, insomnia, muscle cramps, and memory difficulties were identified. Clinical tests on 17 technicians in Rennes showed normal blood pressure, blood sugar, sedimentation rate, blood count, and EEG except minor unexplained variations on three traces. Field measurements at the Metz-Luttange transmitter showed levels from 0.001 to 2.22 mW/cm² in personnel areas.

UHF ELECTROMAGNETIC WAVES AND HUMAN HEALTH

V. M. Malyshev, S. I. Abolonin · 1970

Acute effects involve short-term action of high inte while chronic effects involve action of low-intensity microw. Case histories document chronic disease progression after contact with UHF fields. The monograph concludes with organizational and technical preventive measures. The review notes shortcomings including an unresolved distinction between thermal and nonthermal mechanisms.

THE EFFECTS OF LOW LEVEL MICROWAVE IRRADIATION UPON REFLEXIVE, OPERANT, AND DISCRIMINATION BEHAVIORS OF THE RAT

Nancy Williams King · 1969

Low-level irradiation (1.5–1.7 mw/gm) reduced responding when correlated with reinforcement or extinction but had no reliable effect during uncorrelated presentations. Low-level microwave irradiation did not act as a discriminative stimulus, although acoustic and visual stimuli were well discriminated. High-level irradiation improved tone discrimination performance for rats where the tone signaled reinforcement, and caused curare-like immobility and elevated rectal temperatures.

Electroanaesthesia and the Effects of Pulsed Electrostatic Fields Prior to the Induction Stage

D. P. Photiades, S. C. Ayivorh · 1967

Researchers exposed five male red patas monkeys and five human volunteers to pulsed electrostatic fields of 750 V/cm for one hour per session over ten sessions. The fields were generated by a 16,000 volt source with a 100 c/s ripple, pulsed five times per second between 25 cm square aluminum plates. When electroanesthesia was then administered, subjects pre-exposed to the fields required only 6 to 8 mA of pulsed current versus the full current in controls, and their pulse and blood pressure were 15 to 20% lower with reduced muscle spasm, while other complications were unchanged.
