The human nerve system certain vebrations:
Around 18 Herz, single pictures start to be one moving film. The same speed is valid for our ear: Regular impuls starts to be a sound.
This determins our personal speed of perceptoin as living beings.
Although it can vary a little bit:
In situations of great danger, nerve-vibration can suddenly rise, so we have more time to think what to do: Everything seems to hapen in slow motion. Time Stretches.
Our inner vibration has direct relation to our sens of time.
Low vibration: Time goes by fast.
High vibration: Time seems to be slow.
The so called Schuhmann-frequence:
Between the earth and its atmosphere is electrostatic tension. As a sphere-shaped condensator earth has a distinct resonance frequence about nearly 8 Hz(beats per sec)
Every lightning hits this kind of bell and it keeps on sounding.
As we got born into this vibration, we can not be independent from it.
It is also to take into account, that resonance can happen with possible overtones of this basic frequence of 8 Hz. Our nerve system must be in tune with it.
But we created a lot of artificial vibration and did not care about tune.
The 50 Hz of our electricity-net comes along as a almost perfect sinus wave,
that means it has no overtones, it represents the dullest kind of sound.
All the music we hear is tuned in 12 equal haf tones, to create a circle.
The 440 Hz is an artificial creation.
No wonder, that we lost connection to real nature.
But our voice still creates natural spiral overtones.
