OK, this one's a bit tough to swallow- improving audio by reducing the Schumann Resonance. Fortunately, there's a $450 cure for your ailment.
What is the Schumann Resonance?
The "Schumann Resonance" is a resonance frequency that exists in the Earth's "electromagnetic" cavity; i.e. it exists between terrestrial surface and ionosphere. German physicist W.O.Schumann first detected the resonant properties of this terrestrial cavity in 1954.
It may be said that the Schumann Resonance is a breathing phenomenon of the Earth that is lasting from old time. The lowest-frequency and highest-intensity mode of the Schumann Resonance is at a frequency of approximately 7.83Hz.
Human and all animals and plants have been guarded by this frequency of 7.83Hz and lived for long time. But recently, many unnatural radio waves and electromagnetic waves disturb this frequency of 7.83Hz, it have caused wrong influence on our human bodies.We substantiate that there are many effects when the frequency of 7.83Hz is generated artificially.
