EEG and Your Brainwaves - Binaural Beats.

Technical Notes
The benefits of brainwave entrainment - the process of enhancing your normal
brainwave state - has been known to many scientists and doctors for years.
These benefits include, but are not limited to, improvements in the following
areas: Temporary Pain Relief, Temporary Stress Reduction, Sleeping Disorders,
General Relaxation, and Meditation.
Clinical studies have shown measurable improvement in patients through both
visual and audio biofeedback with respect to attaining a target brainwave
pattern.
Some of the lesser known, more exotic uses for 'Binaural Beat' Therapy, or
'Brainwave Entrainment' are related to the field of PSI, such as remote viewing,
out of body experiences ( OBE ), hypnotism. While it is true that these uses
are not scientifically documented, the general medical uses for audio induced
low frequency has been well documented and is nationally accepted in most
medical circles as 'Biofeedback' and other similar technologies.
How Does It Work?
Our cdroms create sonic tones that, when listened to through stereo headphones
(for best results ) or stereo speakers, will induce low frequency energy
which your brain will attempt to duplicate - or 'entrain' - to. These frequencies
are normal, everyday frequencies found in the EEG waveforms of humans, and
have lead to many interesting and beneficial discoveries.
The 'Binaural Beat' is created by the difference in 'carrier' frequencies
in the left and right channels. For example - to achieve a 4hz Theta Beat,
you could combine a 400 hz tone with a 404 hz tone to produce 404 - 400 =
4 hz. The 'carrier' is always a sine wave.
Some Notes About Binaural Beat Audio You Need To Know:
One of the biggest misunderstandings about Binaural Beats is the use of the
'carrier' tones. The 'carrier' tone is the audible tone - the part you 'hear'.
This tone MUST be pure - the purest tone is a sine wave. If this tone is
complex - like a violin or synthesized sound - the binaural beat target frequency
will be corrupted.
Let me explain: If the primary carrier (a pure sine wave of frequency f1)
contains only the first harmonic which, when mixed with the secondary carrier
(a pure sine wave of frequency f2) of different frequency, will produce a
pure binaural beat of:
|f1 - f2| = f3 (beat frequency)
If we choose any sound other than a sine wave ( square wave, violin, synth
sound, oboe, guitar ) then the carrier itself introduces alternative tone
above the fundamental f1. A typical guitar has strong 2nd and 3rd harmonic
content. So, a guitar note of 100 hz also has 200 hz and 300 hz harmonic
content ( It's what makes a guitar sound like a guitar ). You would expect
that a second guitar note of 104 hz would produce a 4 hz binaural beat when
mixed with the 100 hz primary. It does produce a dominant 4 hz beat
BUT it also introduces a strong 8 hz beat ( 200 - 208 ) at the 2nd harmonic
and a subdued 12 hz beat (300 - 312) at the 3rd harmonic. There are also
many other complex resultant beats if you consider the additions of 1st and
2nd, 1st and 3rd, and 2nd and 3rd harmonics of each carrier. You can see
that the prime objective of 4 hz has been corrupted and while your target
is THETA, you actually get Theta, Alpha, and Beta content which contradict
each other.
|f1a - f2a| = f3a (beat frequency)
|f1b - f2b| = f3b (beat frequency)
|f1c - f2c| = f3c (beat frequency)
We have been asked this by many users why other CDs claiming to have 'Binaural
Beats' sound different ( have talking, ocean sounds, synth - like sounds,
etc. ). The answer is simple: Those CDs are not true Binaural Beat CDs. Yes
- They sound pleasing - but they are not targeted or accurate by any sense
of the word. Simply having a 4 hz resonance in a sound does not make it a
'Binaural Beat'. Generally these products can have a 'placebo' type
effect simply because they sound so 'pleasant' but they do not achieve Brainwave
Entrainment.
Now the downside - pure sine waves are irritating to some people. There is,
however, a compromise. When the pure sine waves are mixed with Diffusion
Noise the 'irritating' effect is reduced and the experience is more pleasurable
for many users - especially those with Tinnitus. Because of Diffusion Noise's
randomness the carrier corruption is minimal and practically no detectable
alternate beating occurs.
The CDs being sold here contain the desired primary beat and may or may not
contain Diffusion Noise - each listing will state this fact. CDs without
Diffusion Noise are for users who prefer a more concentrated (potent) effect
and do not require the Diffusion Noise buffering. Customers may request Diffusion
Noise on any products we offer at no extra charge.
Diffusion Noise Buffering
The Diffusion Noise is a tonally structured ambient background noise based
on noise masking technologies. It has a spectrograph similar in audio response
to an an office or household. It's sound is comparable to a ventilation system
or a vacuum cleaner in the distance. It has it's basis in White Noise, but
has been specifically 'shaped' to provide proper masking and has minimal
objectionable qualities.
Delta Waves ( below 3.5 hz )
This is the frequency range associated with deep sleep. People do not dream
when they are in Delta sleep.
Theta Waves ( 3.5 hz to 7.0 hz )
This is the frequency range associated with a hypnotic, deeply relaxed states
of consciousness. Lucid Dreams are more prone to occur in theta. The
mind is in a twilight state and is prone to free association resulting in
amazing mental images. Many PSI phenomenon are noted to occur in theta such
as remote viewing, out of body experiences, and astral projection.
Alpha Waves ( 7.0 hz to 13.0 hz )
In Alpha, we are awake, but relaxed. Alpha is sometimes described as the
'daydream' state as most daydream activity occurs in persons while in alpha.
There are many reports suggesting relationships between people with Fibromyalgia,
Attention-Deficit/Hyperactivity Disorder, ADD, AD/HD, and other maladies,
that may suffer from excessive Alpha with little Beta activity during the
normal waking day.
Beta Waves ( 13.0 hz to 40.0 hz )
Beta is associated with the fully awake, fully focused mind. High beta without
alpha is associated with stress, anxiety, high blood pressure, and similar
issues.
Facts:
Each of these frequencies occur in nature and are usually associated with
a relaxed state of mind - the crashing of the waves, the babbling of a stream,
the wind through the trees, etc.
Native American Indians produce theta and delta rhythms with their tribal
drum rituals. It is believed that this is the source of their hypnotic states
and mystical experiences.
The U.S. Government itself uses a team of psychics in the famous Stargate
project. It is known that at least one member of this group use binaural
beats to clear their mind prior to remote viewing.
Certain low frequency waves can produce hallucinogenic images. Some believe
this to be the root of many hauntings.
Millions of people who use the Silva mind control courses in the 70's reported
the ability to remote sensing abilities when alpha was achieved.
