schumann resonance

The Schumann Resonance is 7.83 cycles per second (7.83 Hz). Named after Winfried Otto Schumann, the Schumann Resonance is said to be the frequency of the Earth’s vibration. This puts the Schumann Resonance in the ELF (extremely low frequency) range of the Earth’s total electromagnetic spectrum.

The Schumann Resonance is also associated with 13.8 Hz, 19.7 Hz, 25.7 Hz, 31.7 Hz, 39 Hz, and 45 Hz. The exact frequency also varies over time. On top of that, there’s evidence that the Earth's average frequencies are drifting over time too.

At 7.83 Hz, the Schumann Resonance lies within the alpha brain wave range. Therefore, listening to a binaural beat at the Schumann Resonace tends to increase alpha brain wave patterns.
