When I said the exact frequency, for sure this is a also technically some " range" ….
Why Do Schumann Resonators Work?
Schumann Resonators are little boxes you plug into the wall that produce electromagnetic radiation tuned to 7.83 Hz. This is the frequency that the earth/atmosphere system “rings” at when the Earth is struck by lightning. It is also a common frequency your brain “ticks” at.
When employed in the listening room, many people claim it makes their audio sound better. If this is true, then what is the mechanism of action?
-Is it a matter of the resonator producing a more relaxed mental state?
-Does it help block or alter electromagnetic interference?
-Does it add its own electromagnetic interference to your system that just so happens to be pleasing?
I experimented with one recently and what I noticed is that it seemed to remove some of the high frequency nasties or what some might call “digital glare” (although digital glare can also show up in analog systems). When I made this observation, the resonator was placed right next to my power strip that my CD player, preamp and some other devices are plugged into.
My “proof” of the effect is that I could turn the volume up louder than usual without it sounding “too loud.” The sound levels of the system weren’t any quieter, it’s just that the digital glare was reduced so that I could go louder before thinking “this is too loud,” which usually isn’t a sound level thing per se but the point as which some frequency (often the highs) become irritating.
So who here has experience with these devices? Do you like them? Does anyone know why they work?

Description[edit] This global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances occur because the space between the surface of the Earth and the conductive ionosphere acts as a closed waveguide. The limited dimensions of the Earth cause this waveguide to act as a resonant cavity for electromagnetic wavesin the ELF band. The cavity is naturally excited by electric currents in lightning. Schumann resonances are the principal background in the part of the electromagnetic spectrum[2] from 3 Hz through 60 Hz,[3] and appear as distinct peaks at extremely low frequencies (ELF) around 7.83 Hz (fundamental),[4] 14.3, 20.8, 27.3 and 33.8 Hz.[5] In the normal mode descriptions of Schumann resonances, the fundamental modeis a standing wave in the Earth–ionosphere cavity with a wavelength equal to the circumference of the Earth. This lowest-frequency (and highest-intensity) mode of the Schumann resonance occurs at a frequency of approximately 4.11 Hz, but this frequency can vary slightly from a variety of factors, such as solar-induced perturbations to the ionosphere, which compresses the upper wall of the closed cavity.[citation needed] The higher resonance modes are spaced at approximately 6.5 Hz intervals,[citation needed] a characteristic attributed to the atmosphere’s spherical geometry. The peaks exhibit a spectral width of approximately 20% on account of the damping of the respective modes in the dissipative cavity. The 8th partial lies at approximately 60 Hz.[citation needed] >>>>>>Translation: The Schumann resonance is not a range of frequencies, it’s a set of frequencies. The Schumann fundamental is 7.83 Hz and associated harmonic peaks. So, if a device can’t produce the 7.83 Hz fundamental accurately the “peaks” will not be produced accurately either. |
Thanks Geoffkait I get the point.... I presume that my cheap inexact S.G. works my "room acoustic" tough, nevermind being accurate, because they enhance the effect of the stones associated or connected to them... I said so because the effect is very audible.... I am no scientist and never pretend to explain something, just describing my experience.... My best to you...
