SH88 Frequency Excitation Unit

The rotation period of our planet Earth is 24 hours. This equates to 86,400 seconds per day.

Therefore the rotational frequency of the Earth is

1/86,400 Hz = 0.00001157 Hz

If you are familiar with musical theory, then you will probably know that any two notes an octave apart will have frequencies, where the higher note has a frequency twice the frequency of the lower note.

If you double the frequency of the Earth 24 times, 25 times and 26 times (octaves), you will end up with the three audible frequencies in the table below.

Earth Octave	Frequency
26th Harmonic	776.72 Hz
25th Harmonic	388.36 Hz
24th Harmonic	194.18 Hz

These are the 3 Earth Special Frequencies. By selecting any of these frequencies, you can feel linked with and synchronised with our planet.
