Hemi-Sync: Self Experiment

Here is some data one might find useful if experimenting with
sound synthesis and/or hemispheric syncronization.

It might be useful to note that, with a few exceptions, most music
synths do not use the frequency tables in their display, but opt
for digital +/- 64 or 128 as the values for fine tuning. If you
know what notes you are playing with, the table below will give
you the specific frequencies for four octaves, and you can do some
simple math to find out what the divisions are for your specific
synth or software. If you are programming using computer language,
you may be able to enter specific frequencies between the intervals
to produce narrow binaural beats.

What I have found most useful though is my keen ear, and lots
of patience for aproximating binaural beats, but if you have all
the data present, doing it by the numbers may be faster and more
accurate. Most modern Samplers, such as the Kurzweil K2000, let
you work extensively with sampled and internal sounds, and the
K2000 (my personal choice) has tons of synthesis functions, and
real-time values such as A=440.00 for fine tuning by hertz and
other value system (semitones, etc.).

Right now I am using an EMU Vintage Keys MIDI sound module and
it works great for this and is easy to program frequencies quickly,
has loads of Moog, Prophet, ARP and other classic synth waves
in it, and its cheap! (About $600.00)

Someone sent this to me a while back. I have no idea of how
accurate it is, but from my estimations, the only frequencies
you will need to work with are contained within the 1 to 30 Hz
range or from Delta through Beta.

I cannot comment on any frequencies beyond the normal 30 Hz waking
state, as I have no solid info on the effects. Use at your own
risk!

->Delta: 0.1 to 3 Hz.
->The Delta level is normally associated with a deep  dreamless
sleep, trance state, and non-REM type of  sleep:

->1.00 Hz  Feeling of well-being; pituitary  stimulation to release
growth hormone;  overall view of inter-relationships.

->Theta: 3 to 7 Hz.
->The Theta level is normally associated with recall,  fantasy,
imagery, creativity, inspiration, future  planning, dreaming,
switching thoughts, and  drowsiness.

->3.50 Hz  Feeling of one with everything; accelerated  language
retention.
->5.50 Hz  Moves beyond knowledge to knowing; shows  visions of
growth needed.
->6.30 Hz Mental and astral projection; accelerated  learning
and increased memory retention.

->Alpha: 7 to 13 Hz.
->The Alpha level is associated with a non-drowsy but  relaxed,
tranquil state of consciousness, primarily  with pleasant inward
awareness; body/mind  integration.

->7.00 Hz Mental and astral projections; bending  objects; psychic
surgery.
->7.50 Hz Inter-awareness of self and purpose; guided  meditation;
creative thought for art,  invention, music, etc.; contact with
spirit  guides for direction.
->7.83 Hz Earth resonance (Beck).
->8.00 Hz Level for past life regression.
->8.30 Hz Pickup visual imagery of mental objects.
->9.00 Hz Awareness of causes of body imbalances and  means for
balance.
->10.50 Hz Frequency to go for healing of the body;  mind/body
connection; firewalking.
->12.00 Hz Centering; frequency of earth resonance  (Hercules
- a researcher).

->Beta: 13 to 30 Hz.
->The Beta level is associated with outward awareness,  the taking
in and evaluating of various forms of  data received through the
senses; it is present with  worry, anger, fear, hunger, and surprise.

->13.00 Hz - 30.00 Hz is the NORMAL awakened,  daily functioning
state.

->High Beta: 30 to 500 Hz.
->The High Beta level is not associated currently with  any state
of mind. Some effects have been observed,  but currently not enough
research has been done in  this area, to prove, or disprove, anything.

->35.00 Hz Awakening of mid-chakras; balance of  chakras.
->55.00 Hz Tantric yoga; stimulates the kundalini.
->63.00 Hz Astral projection.
->70.00 Hz Mental and astral projection.
->80.00 Hz Awareness and control of right direction.
->83.00 Hz Third eye opening for some people.
->90.00 Hz Good feelings; security, well being,  balancing.
->105.00 Hz Overall view of complete situation.
->108.00 Hz Total knowing.
->120.00 Hz - 500.00 Hz P.S.I.; moving of objects, changing
matter;  transmutation.      Well, I hope this helps you in your
own experimentation! At the least, working at programming synthesizers
and achieving good results can be an exercise in futility. But
in the process you will always learn something new, and probably
come away with a new appreciation of audio engineers, if not an
improved ear for sounds.

From my own experience, I would probably have to recommend most
people continue to use the excellent Monroe Hemi-Sync products.
They are a proven method, and I have not found their equal. Even
my own attempts at producing "Hemi-Sync" have fallen far short
of the TMI methods, but it is fun tinkering around with this technology
anyway. Maybe you can pick up where I left off.

Have Fun Kids!
