Schumann wave does not directly act on speakers or video products to improve sound quality, but acts on the space environment. Schumann wave 7.83Hz offsets the frequency of negative interference from electromagnetic waves, which makes the sound space reverberation stable and harmonious, allowing listeners to enjoy music more concentrated and enjoyable. It can improve the human body's perception of sound and images, improve the health of the human body, improve the efficiency of work creation, and also have a good effect on insomnia and mental stress. The Schumann wave generator itself does not emit any sound, and is not connected to other devices. It can be used only when plugged in.
