What are the brain frequencies?
Electrical instruments
(electroencephalographs) are commonly used by medical people to evaluate
mental states. These instruments measure the neuron firing rates of groups
of brain cells. These firing rates are commonly thought to control mental
states. Beta, alpha, theta and delta are terms that medicine uses to
indicate the rates of brain cell firing and the corresponding mental
states associated with them.
The Beta State
The beta state is that state of mind that you
experience when awake and active during the day. It includes any brain
wave with a frequency greater than or equal to 13 Hz (faster repetition
than 13 times per second). Beta states above 20 Hz are generally classed
as higher beta or gamma.
The higher beta state, often referred to
as the gamma state, is experienced while wide-awake and highly aroused.
The higher beta state is very stimulating and can be associated with
anxiety. This anxiety could be related to subconscious resistance to these
states. The brain wave amplitudes tend to be very small. This is the type
of frequency used in the Energizer programme.
The lower beta state
is that state of mind commonly experienced while awake and busy during the
day. This is the state of mind in which you commonly deal with your daily
routines. You can experience anxiety with some of the lower beta
frequencies. The low beta state involves frequencies from 13Hz to 20Hz.
The amplitudes are generally quite small. This type of frequency has been
used successfully as a harmonic of lower frequencies to create unusual
effects.
The
Alpha State
The
alpha mind state is that state commonly experienced while the body is
resting and the mind is calm. The alpha state is the one you experience
whilst doing a mundane repetitive task with nothing particular on your
mind. A typical example would be driving a car (how many times have you
driven from work and barely remembered the journey?). The alpha state of
mind involves frequencies from 8.0 to 12.9Hz. The natural amplitudes tend
to be larger than beta. .
Note: You can quickly induce alpha
state by closing your eyes and generally looking upwards, allowing your
eyes to roll backwards.
The Theta State
The theta state is commonly experienced in deepened states
of meditation, at the onset and in lighter parts of sleep. It seems to be
present in hypnogogic and hypnopompic hallucination. It is characterised
by frequencies from 4.0Hz to 7.9Hz. It is believed by some scientists that
high amplitude Theta frequencies accompany most (if not all) psychic
activity.
The Delta & Epsilon State
The Delta and epsilon mind state is commonly
experienced at night during deep sleep or possibly during the day by
people experiencing depression or mental fatigue. The Delta state of mind
involves frequencies from approximately 0.1Hz to 4Hz. The epsilon state
involves frequencies lower than 0.1Hz . The natural amplitudes are large
in size. These frequencies are the least researched and are common in very
deep trance states.
What are binaural
harmonics?
The
sensation of auditory binaural beats occurs when two coherent sounds of
nearly similar frequencies are presented to each ear with stereo
headphones or speakers.
If the left ear is presented with a steady
tone of 200Hz and the right ear a steady tone of 210Hz, these two tones
combine in the brain. The brain integrates the two signals, producing a
sensation of a third sound called the binaural beat. This 10Hz beat signal
is formed entirely by the brain.
In binaural harmonic technology
the 200Hz and 210Hz frequencies are known as carried frequencies. The
frequencies used are pure sine wave generated
frequencies.
Binaural beats originate in the brainstem's
superior olivary nucleus, the site of contra lateral integration of
auditory input.
The binaural best is neurologically conveyed to the
reticular formation which uses neurotransmitters to initiate changes in
brain-wave activity.
Binaural beats can be perceived only when the
right-ear and left-ear tones used to produce them are of low pitch,
usually less than 1500Hz.
Brainwave harmonics use carrier
frequencies of less than 150Hz. These lower frequencies are thought to be
more soothing.
Monaural beats produced with two tones of equal
intensity sound clean and pure.
Binaural beats initially have a
slight warbling sound as your brain adjusts this will disappear.
To
produce perfect monaural beats the amplitudes of the two tones have to be
identical.
Binaural beats maintain their intensity regardless of
the relative amplitudes of the right-ear and left-ear tones even if one
ear is below threshold (a hearing loss in one ear may not reduce the
effectiveness of binaural beats).
Masking monaural beats with noise
eliminates the perception of beating and the measurable EEG
frequency-following response.
Masking binaural beats with white or
pink noise does not decrease their effectiveness.
What is brain
entrainment?
If
binaural frequencies are applied to the brain, it becomes possible to
entrain the brain frequency from one stage to another. For example, if a
person is in beta state and a binaural frequency of 12Hz is applied to
their brain for some time, the brain frequency is likely to change towards
the applied frequency. The effect will be relaxing to the person. This
phenomenon is also called frequency following response.
When the
brain's dominant frequency is close to the applied frequency, entrainment
works more efficiently. Thus, when doing a sweep from one frequency to
another, the starting frequency should be as close to your current brain
state as possible. The sweep speed should be such that your brain's state
changes steadily with it, so that the difference never gets very
large.
You could liken the effect to a tuning fork or the harmonic
vibration of a glass.
Most of the brainwave harmonic
programmes start from 18Hz - 20Hz and sweep down to the required
harmonic.
What makes brainwave
harmonics different?
Brainwave harmonics make use of binaural technology to
produce very specific combinations of frequencies in the
brain.
These frequency combinations work like a key or a software
programme to unlock a specific function of the brain.
Scientists
thought for many years that psychic phenomena were associated with
particular brain states and particularly Theta or Alpha states. The reason
why psi was so sporadic was that the correct brainwave combinations seemed
to be produced randomly.
Brainwave Harmonics used the information
to experiment with different, specific combinations of frequencies and to
lock the brain into those frequencies using entrainment or frequency
following.
Single binaural frequencies will most certainly work to
make you more relaxed, increase your ability to learn, improve your memory
and in many cases reduce your need for sleep.
The correct multiple
programmed frequencies will provide very specific extrasensory effects.
The E book 'Secrets of Brainwave Harmonics Revealed' will indicate which
frequencies are used for each effect. It will also give you a list of
experimental frequencies compiled from different researchers.
There
are no subliminal suggestions or verbal prompts on any of the harmonic
programs.

auditory beats affect vigilance performance and mood. PHYSIOL BEHAV 63 (2)
249 252, 1998. - When two tones of slightly different frequency are
presented separately to the left and right ears the listener perceives a
single tone that varies in amplitude at a frequency equal to the frequency
difference between the two tones, a perceptual phenomenon known as the
binaural auditory beat. Anecdotal reports suggest that binaural auditory
beats within the electroencephalograph frequency range can entrain EEG
activity and may affect states of consciousness, although few scientific
studies have been published. This study compared the effects of binaural
auditory beats in the EEG beta and EEG theta/delta frequency ranges on
mood and on performance of a vigilance task to investigate their effects
on subjective and objective measures of arousal. Participants (n = 29)
performed a 30-min visual vigilance task on three different days while
listening to pink noise containing simple tones or binaural beats either
in the beta range (16 and 24 Hz) or the theta/delta range (1.5 and 4 Hz).
However, participants were kept blind to the presence of binaural beats to
control expectation effects. Presentation of beta-frequency binaural beats
yielded more correct target detections and fewer false alarms than
presentation of theta/delta frequency binaural beats. In addition, the
beta-frequency beats were associated with less negative mood. Results
suggest that the presentation of binaural auditory beats can affect
psychomotor performance and mood. This technology may have applications
for the control of attention and arousal and the enhancement of human
performance. ©1998 Elsevier Science Inc.

Accessing Anomalous States of Consciousness with a
Binaural Beat Technology
The Monroe Institute, 62 Roberts Mountain
Road, Faber, VA 22938-2317
Abstract - Exposure to binaural beats in
an environment of restricted stimulation coupled with a guidance process
can safely provide access to and experiences in many propitious states of
consciousness. This method requires a unique combination of
well-understood psycho-physiological inductive techniques with the
addition of a refined binaural-beat technology. Binaural beats provide
potential consciousness-altering information to the brain's reticular
activating system. The reticular activating system in turn interprets and
reacts to this information by stimulating the thalamus and cortex thereby
altering arousal states, attentional focus, and the level of awareness,
i.e., the elements of consciousness itself. This effective binaural-beat
process offers a wide variety of beneficial applications and vehicle for
the exploration of expanded states of consciousness.
