7.83 Hz Pure Schuman Resonance | 10 Hour Binaural Beat | Black Screen

The Schumann resonance has been described as the "atmospheric heartbeat" of the earth. All across our planet, right now, thousands of thunderstorms are discharging their stored electrostatic energy in the form of lightning strikes at a rate of about 50 strikes per second, producing powerful electromagnetic waves that travel through our atmosphere.

These waves are trapped between the earth's surface and a layer of charged particles high in the upper atmosphere (known as the ionosphere). This space creates a resonant cavity, as in a tubular bell, that "rings" at its fundamental frequency. This frequency is that whose wavelength is equal to the length of the resonant cavity. In this case, the length of the resonant cavity is the circumference of the earth, and we can roughly calculate the fundamental frequency using the wave equation, f = v/λ. By dividing the wave's propagation speed c, the speed of light in a vacuum (about 300 million m/s), by our desired wavelength (Earth's circumference, about 40 million meters), we get f ≈ 300,000,000/40,000,000 * m/(m*s) = 7.5 Hz.

This resonance was mathematically predicted by physicist Winfried Otto Schumann in 1952, and has since been more precisely measured at 7.83 Hz.
