The Schumann Resonance is a 7.83 Hz frequency resonance that is naturally occurring and generated by lightning in the earth's atmosphere.

Its fundamental frequency falls within the Theta wave range which is linked to deep relaxation, meditation, and REM sleep.

Some believe that it is the Earth's heartbeat and that it provides grounding and inner balance. It is also believed to facilitate meditation, healing, and spiritual awakening.

This sound features Alpha waves at 10 Hz with a low, 150 Hz carrier tone.

Like Delta waves, Alpha waves are also associated with reduction of stress and anxiety. They differ, however, in that they are a wakeful brainwave. They are tied to mindfulness, neurofeedback, and relaxed wakefulness as well as calm focus.

Some believe that Alpha waves are the bridge between the conscious and subconscious mind. Some use these beats for creativity, euphoria, visualization, or even manifestation.

This sound features Delta waves at 2Hz with a low, 150 Hz carrier tone.

Delta waves are the slowest brainwave state and are most present during deep, restorative sleep. They are also linked with healing and immune system regulation and relief from stress and anxiety.

Some believe that Delta frequencies promote faster healing, cell regeneration, or even connection to universal consciousness.
