7.83Hz is below the threshold of human hearing (20Hz). This tool uses a carrier tone (binaural beat) to make the resonance perceptible.

The Earth's Pulse

The Schumann resonances are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. The fundamental frequency is approximately 7.83 Hz, which intriguingly aligns with the low Alpha / high Theta brainwave states in humans.
