Earth, Moon & Sun
Earth, Moon and Sun cycles turned into tones you can hear by doubling their frequency, plus measured Earth frequencies such as Schumann resonance.
20 entries, lowest frequency first: 6 measured, 12 derived, 2 speculative.
Entries
- Solar Cycle (11-year)MeasuredThe activity of the Sun rises and falls over about 11 years: sunspots, flares and geomagnetic storms.2.90 × 10⁻⁹ Hz
- Schumann Resonance (Fundamental)MeasuredA radio-wave resonance of the Earth’s atmosphere, measured near 7.8 Hz. It is not a sound and cannot be heard.7.83 Hz
- Schumann Resonance (2nd mode)MeasuredThe second mode of the cavity between the ground and the ionosphere.14.30 Hz
- Schumann Resonance (3rd mode)MeasuredThe third mode of the cavity between the ground and the ionosphere.20.80 Hz
- Schumann Resonance (4th mode)MeasuredThe fourth mode of the cavity between the ground and the ionosphere.27.30 Hz
- Schumann Resonance (5th mode)MeasuredThe fifth mode of the cavity between the ground and the ionosphere.33.80 Hz
- Sun Tone (Cousto’s construction)DerivedA tone Hans Cousto constructs for the Sun. It is not a measurement of anything the Sun does.126.22 Hz
- Earth Year (Cosmic Octave)DerivedOne Earth year, doubled 32 times, comes to this tone. It is calculated, not recorded: the orbit of the Earth makes no sound.136.10 Hz
- Platonic Year (Cosmic Octave)DerivedThe slow wobble of the Earth’s axis, counted by its traditional length of 25,920 years and doubled 47 times.172.06 Hz
- Moon Culmination Period (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 24 times. It is calculated, not recorded.187.61 Hz
- Earth Synodic Day (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 24 times. It is calculated, not recorded.194.18 Hz
- Earth Sidereal Day (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 24 times. It is calculated, not recorded.194.71 Hz
- Moon Synodic Month (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 29 times. It is calculated, not recorded.210.42 Hz
- Moon Sidereal Month (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 29 times. It is calculated, not recorded.227.43 Hz
- Moon Metonic Cycle (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 37 times. It is calculated, not recorded.229.22 Hz
- Moon Node Circulation (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 37 times. It is calculated, not recorded.234.16 Hz
- Moon Saros Period (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 37 times. It is calculated, not recorded.241.56 Hz
- Moon Apsides Rotation (Cosmic Octave)DerivedA tone calculated from a measured cycle, by doubling its frequency 36 times. It is calculated, not recorded.246.04 Hz
- Atmospheric sferics, 4150.84 Hz (Baumer/Cousto)SpeculativeA figure reported for radio pulses from lightning. Cousto links it to the rotation of the Earth; the link is a musical fourth, and approximate.4,150.84 Hz
- 351 nm “DNA resonance” (Cousto)SpeculativeA figure Hans Cousto reports from a personal communication. The measured peak of DNA’s ultraviolet absorption is elsewhere, near 260 nm.854 THz
