This product is a 7.83 Hz low frequency Schumann waves generator featuring high accuracy and stability.Schumann electromagnetic waves are low frequency and can penetrate any material.Each individual has a network of weak currents that will produce frequency resonances when excited by Schumann waves.The overall equilibrium of the human meridians is maintained by receiving the Schumann electromagnetic field and the cellular frequency resonance of the human body to reduce the damage caused to the human body by the EMF ionizing radiation.Human frequency resonances can be induced, complementing natural geomagnetic and artificially attenuated electromagnetic field (EMF) interference, and equilibrating the membrane potential equilibrium.The Schumann waves generator itself does not make any sound, and it is not directly acting on the sound or video products to improve the quality of sound or vision, but it plays a role in the space environment, it can help relax people's physical and mental, and it helps improve the body's perception of sound and imaging, and it also helps the human body more healthier to improve the work efficiency.Name: Schumann Resonance GeneratorPower: 5WFrequency: 7.83HzInput power: 5VInterface: USBColour:As ShownMaterial:plasticSpecification: A: with housingPackage Contents:1 x Schumann Resonance Generator1 x USB Cable1 x Transparent Housing
