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.
