The Exposure Mechanism of High-Frequency Modulated Signal on Unideal Non-Conductor. Radiohearing

Abstract

The article is related to the electromagnetic compatibility. Microwave auditory effect was analyzed as the observed phenomenon of high-frequency radio signals transformation into acoustic oscillations. This phenomenon was called a radio hearing effect. This sensory-acoustic effect is a natural phenomenon associated with the conversion of electromagnetic energy in the lowfrequency mechanical vibrations on the way to the receptor system by bone conduction. The physical interaction mechanisms of amplitude-modulated high-frequency electrical signal with a perfect nonconductor were considered, leading to a transformation in the low frequency mechanical vibrations or acoustic harmonics of the modulated signal. In the paper studies of the possible effects of direct exposure to high-frequency field in medical practice, or physical therapy are presented. The mechanisms of interaction of the modulated RF signal with a weakly absorbing material with goal to detect electro-acoustic effect were presented. The presence of inertial nonlinear conversion effect of a modulated RF signal into low frequency sound is confirmed.
