About Schumann Wave: In 1952, Schumann pointed out that the earth and the ionosphere can form a resonant cavity. There is a special resonant frequency in the cavity. This frequency is mainly determined by the size of the earth and is excited by fulmination and electric discharges around the world. This resonant frequency is called Schumann Resonance. The spectrum of Schumann resonance is in the ELF band, and the frequency is about 8 Hz (there is a lot of saying about this value, 7.83/7.5/7.2, etc.). It happens that the for alpha wave and theta wave of the human brain are also close to 7.8 Hz, so some people call Schumann resonance As "the brain waves of the earth." About Products: Size: 10*10*1.4cm Power supply: 12V power supply (included) Delivery includes: 1*Schumann wave generator 1*Data cable The significance of Schumann wave to humans: It is said that "N-A-S-A" installed the Schumann wave generator in the manned space cabin to maintain the physical and mental for health of astronauts. However, various communication radio waves and high-voltage wires may interfere with and change the Schumann wave. The Schumann wave is a low-frequency wave that can penetrate any material, including people on the ground. Each of us is equivalent to an electrical network. If it is constantly excited by Schumann waves, resonance may occur; as for the strength of the resonance, it is related to the internal structure of the electrical network (human body). Some human body's electrical network has a better structure and can easily receive Schumann waves; some people do not, and can only receive weak Schumann waves. The situation is similar to that of radio frequency modulation. Because Schumann wave is a natural energy source, it is inexhaustible. Therefore, anyone who is easy to resonate with Schumann wave is equal to charging frequently, naturally full of energy and healthy. Schumann wave itself does not directly act on audio or video products to improve the sound quality and picture quality, but acts on the space environment to relax the body and mind, improve the human body's perception of sound and images, improve the human body's for health, increase the efficiency of work creation, and prevent insomnia. , Mental stress, etc. also have a better effect. Used in the audio-visual space-improve the sound field and audio-visual effects Used in the bedroom-to help sleep soothe the nerves, adjust insomnia Used in the office-relax and improve work efficiency For creative space-to improve for creative inspiration Used for tea ceremony and Zen enlightenment space-calm body and mind However, due to the effect on the state of mind, the human body has different sensitivity to the environment, that is to say, it also depends on the state of mind and feeling, so the effect of the product is not intuitive.
