Description
Schumann resonance frequencies are electromagnetic waves excited by lightning along the circumference of the earth. The poorly conductive earth surface (mostly salt water) and the highly conductive ionosphere above limit a cavity resonator from whose dimensions possible resonance frequencies can be calculated. Waves that are in the same phase again after an earth orbit (or the circumference of the earth is an integer multiple of the wavelength) are amplified, others extinguish themselves. This results in a lowest resonant frequency of 7.83 Hz on average; see Wikipedia
7.83 Hz, five octaves higher, gives a tone of 250.56 Hz. The octave correspondence of this frequency in the light spectrum can be seen as yellow-green.
– Planetware – Schumann Resonance 250.56Hz standard or large tuning fork
– Manufactured using high quality nickel-plated steel.
– Ergonomically shaped soft grip handle making it easier and more comfortable to use during sonopuncture.
Tuning: Accuracy of +/- 0.5% (a semitone is 100%)
– 250.56Hz
Note: The Planetware tuning fork audio files are synthesizer representations of the exact frequency. Not a recording of the tuning fork itself.
