SMR frequency / Schuman resonance

These two frequencies are mentioned here and there, but I haven't found any info regarding why their importance for AVS. What is so special about them and why are they being used in AVS?

Have you read this thread?

Thanks for the link. It is only about Schumann, not SMR, it is huge, kind of philosophical, with a lot of jargon and hard to follow for me as a newbie.

By SMR are you referring to the general frequencies of the brain?

You got some answers about SMR already in your earlier post. What questions do you still have?

What one is hoping to achieve if they use the SMR frequency on an AVS device.

Schumann resonances are background frequencies which are predominant between the earth's surface and the ionosphere. They are excited by lightning strikes. https://en.wikipedia.org/wiki/Schumann_resonances

The actual frequency at any given time varies around 7.5 to 8hz. However, a recognized fundamental which has acquired an almost mythical character is 7.83hz. There are other upper frequencies which are referenced in the article above.

The company HeartMath sponsors a network of global antennas which measure these frequencies. You can read more about that and see the record of the live data feed here: https://www.heartmath.org/gci/

These frequencies are considered important to human neural rhythms as they are part of the background radiation which we have evolved under for millions of years. It is quite interesting that they fall within the range of human brainwaves. 7.83hz is also a borderline frequency between low alpha and theta.

SMR stands for sensorimotor rhythm. https://en.wikipedia.org/wiki/Sensorimotor_rhythm

This range of frequencies is in the lower beta band. In most individuals, between 13 to 15hz. It is considered important as it is an alert yet relaxed state related to focused attention to mental tasks. Neurofeedback often trains for control of this.

Hope this helps,
