The Schumann Resonances are quasi-standing electromagnetic waves that exist in the Earth's 'electromagnetic' cavity (the space between the surface of the Earth and the Ionosphere). Like waves on a string, they are not present all the time, but have to be 'excited' to be observed. They are not caused by anything internal to the Earth, its crust or its core. They seem to be related to electrical activity in the atmosphere, particularly during times of intense lightning activity. They occur at several frequencies, specifically 7.8 (strongest), 14, 20, 26, 33, 39 and 45 (weakest) Hertz, with a daily variation of about ± 0.5 Hertz. So long as the properties of Earth's electromagnetic cavity remains about the same, these frequencies remain the same. Presumably there is some change due to the solar sunspot cycle as the Earth's ionosphere changes in response to the 11-year cycle of solar activity. The resonant properties of this terrestrial cavity were first predicted by the German physicist W. O. Schumann between 1952 and 1957, and first detected in 1954.
Depending on your point of view, living beings either evolved in this natural electromagnetic environment or were created with Divine Intelligence to live in harmony with it. One thing is certain: Since life began, the Earth has been surrounding all living things with this natural frequency pulsation. Many experts believe that the wide spectrum of artificial man-made EMF radiation masks the natural beneficial frequency of the Earth. Electropollution may cause us to feel more stressed, fatigued and "out of balance." Laboratory research has shown that exposing living cells to the Schumann Resonance had beneficial effects when also exposed to ambient EMFs, allowing the cells to increase their immune protection, and decrease the absorption of depression-inducing chemicals. Some researchers believe that by producing a 7.83 Hz signal with a field generator (Schumann device), we can reduce the irritating effects of man-made fields. By replicating the Earth's natural rhythm, we may be providing ourselves (at least in our immediate vicinity) with a more healthy environment.
The strength of the Earth's Schumann Resonance is very weak and requires sophisticated equipment to detect it.According to Wikipedia:
"The Schumann resonance electric field amplitude (~300 microvolts per meter) is much smaller than the static fair-weather electric field (~150 V/m) in the atmosphere. Similarly, the amplitude of the Schumann resonance magnetic field (~1 picotesla = 10-5 mG) is many orders of magnitude smaller than the Earth's magnetic field (~30–50 microteslas)."
We have listed below several products that are field generators of the 7.83 Hz frequency, the rhythm of the Earth itself!
SCHUMANN SIGNAL GENERATOR
Tunable, Adjustable, Powerful
The benefits of the Schumann Resonance have been discussed at length. With this device you can precisely select any frequency from 0.01 Hz to 2 MHz, and adjust the power output as well. Produces a mammoth intensity signal: from 1 mG to over 50 mG! (Compare that to the strength of the Earth's Schumann resonance at 10-5 mG) Detectable up to 4 feet away. Digital display leaves no uncertainty about what frequency is selected. Includes memory for up to 10 favorite frequencies. USB powered from your computer or 50/60Hz 100-240V Universal AC adapter (provided).
Have you wondered what the Schumann Frequency sounds like? This unit can also be used as an Audible Tone Generator or Frequency Counter. Includes amplified speaker which you can use to listen to any frequency you select. Produces Sine, Sawtooth and Square wave patterns. Step by step instructions included. Puts the full power of the Schumann Resonance in your hands!

REPLACEMENT JUMBO COIL
Need a replacement or secondary coil? Almost 4.75 x 8 inches, this large coil can be also used as an AC magnetic field sensor, or AC/DC magnetic field producer. Generates an AC voltage when exposed to AC magnetic fields. Although we do not specify how the output from this unit varies with frequency, we do know that the greater the magnetic field, the higher the voltage generated. It can be connected to a DMM, voltmeter, oscilloscope, audio amplifier, or recording device. It can also be used in reverse: apply a small AC or DC current to produce a magnetic field (careful, don't overdo it). Has color coded binding posts and a stable base. Great for teaching principles of electromagnetism and magnetic induction. Same coil as is included with the Schumann Signal Generator above.
This has to be the easiest way to take the Schumann Resonance with you wherever you go. Only 2¼*2¾ inches, it will easily fit in your purse or pocket. Runs about 200 hours on a 6 hour charge. Includes USB cord for charging. Produces clean 7.83 Hz (not adjustable) signal which covers a few feet of area. Straight forward on/off switch is the only control. Sturdy semi-transparent case lets you see the internal workings. High quality polymer batteries included, with overcharged, overvoltage, overcurrent protection.
