The Schumann Resonance
The Schumann Resonance is named after Winfried Otto Schumann.
The Schumann Resonance is the frequency of the Earth's vibration. There are a number of different frequencies involved but the Schuman Resonnace is usually said to be 7.83 Hz or 7.83 cycles per second. The Schumann Resonance is in the ELF (extremely low frequency) range of the Earth's total electromagnetic spectrum.
The other frequencies associated with the Schumann Resonance are 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. (out of tune or in tune?)
At 7.83 Hz, the Schumann Resonance lies within the alpha brain wave range. Therefore, listening to a binaural beat at the Schumann Resonace will increase alpha brain waves.
