NEW Schumann wave generator 7.83Hz very low frequency electromagnetic wave Schumann wave resonance
Schumann wave is an extremely low frequency electromagnetic wave that exists in the Earth and is excited by a lightning discharge with a wavelength approximately equal to the circumference of the Earth. The frequency of the Schumann wave is controlled by the Earth&39;s ionospheric waveguide, with a dominant frequency of 7.83 Hz. The frequency of the alpha and theta waves in the human brain wave is also close to 7.8 Hz, that is, our nervous system will react to the electromagnetic pulse Schumann wave.
