The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth''s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth''s surface and the ionosphere.
Schumann wave itself does not make any sound, it is not directly acting on the sound or video products to improve the quality of sound or vision.
It''s working on the space environment, make the people''s physical and mental get relaxed, improve the body''s perception of sound and images, improve the human body health and working efficiency.
It also has a good effect on insomnia, mental strain and so on. For more information please Google ''Schumann Resonance''. Can be used with quantum crystal, enhance the improvement of space resonance, strengthen the anti-shock, improve the launch efficiency and stability
Please note that in order to protect its acrylic boards, the transparent and black version are shipped as components, and you need to assemble them by yourself (very easy), while the wood version is a completed product.
