Waha Dizigov. For the first time the effect of standing waves was discovered by Nikola Tesla, and only after more than five decades, this effect was more thoroughly investigated, and became known as the "Schumann Resonance." The assumption of the existence of the resonance of electromagnetic waves in the Earth-ionosphere expressed in years, 50s, Professor, University of Munich, Otto Schumann. For 60 years, after numerous studies and rechecking was accurately determined standard frequency 7.83 Hz of the Earth. Since then, in science, this frequency is called the Schumann resonance frequency of a wave or Schumann. Some scientists and researchers all frequency radiation of the Earth is often called waves Shumana.V now frequency of 7.8 Hz is the main instrument for magnetic therapy. Earth and the surrounding air layer is formed giant spherical cavity. In terms of radio engineering are two huge areas that are placed in a druguyu.Mezhdu they are cavity bounded by conducting surfaces.

In this cavity, according to experts, a well-defined waves propagate dliny.Krome chastototy Schumann also identified other frequencies – 8, 14, 20, 26, 32 Hz. It is believed that at higher frequencies, the resonances are almost invisible. These frequencies are practically identical with the frequencies of alpha and beta rhythms of the human brain. Experts divided brainwaves into four categories, each corresponding to a particular level of consciousness. The unit of measurement of brain waves – as is the case with sound waves – is hertz (Hz). 1. Beta waves, from 14 to 20 Hz.
