This product can output a 7.83Hz Schumann wave, with the frequency adjustable from 0.01Hz to 9999Hz.

Schumann waves do not directly improve the sound quality of audio or video products. Instead, they work by improving the spatial environment, relaxing people, enhancing the body's perception of sound and images, improving health, increasing work efficiency, and relieving stress.

Note: The Schumann resonance generator does not produce any vibration or sound when it is working.
