Product description

Does this device make any noise while running?

No, the Schumann resonance generator operates silently using electromagnetic fields, not sound waves. However, you can plug in the included headphones to hear the frequency converted into an audible tone if you wish to verify it.
Can I use this for electronics projects or oscilloscope testing?

Yes, this is a versatile generator supporting 0.01Hz-200kHz with Sine, Square, and Reverse Square waves. It features an audio output that can be connected to an oscilloscope or for educational and laboratory purposes.
Is the frequency adjustable or fixed at 7.83Hz?

While pre-set to 7.83Hz (Schumann Resonance) for optimal sleep benefits, the frequency is fully adjustable from 0.01Hz to 200kHz. You can customize it for different meditation techniques or specific experimental needs.
