Schumann Resonance Generator,Wood 7.83hz Pulse Generator Low Frequency Ambience Generator Mute Schumann Wave Generator with 110V-240V Ac Power Power Supply…
Stable Schumann frequency Generator:7.83HZ Schumann Wave Ultra-low Frequency Pulse Generator,It emits the ultra low frequency which provides a stable "ambience" within which you listen to your stereo with more perceived clarity.
Schumann Resonances&Earth's frequency:The Earth behaves like a gigantic electric circuit. Its electromagnetic field surrounds and protects all living things with a natural frequency pulsation of 7.83 hertz on average — the so-called “Schumann resonance,” named after physicist Dr. Winfried Otto Schumann.
How does the Schumann resonance affect US? Being in the Schumann wave ambience can reduce anxiety, insomnia, and reduce the negative impact of EMF on the body..
quiet Schumann frequency Generator：There is no noise at work, you will not even notice its “existence”.
With AC power adapter: it can be used in sleep and work when plugged in. In order to achieve better results, it is recommended to stay away from electromagnetic radiation equipment when using.
