Entrainment With Binaural Beat Frequency Technology
In response to repeated requests, we are now offering brain wave
entrainment technology based on our binaural beat frequency research
to the general public. Use of these binaural beats results in brain
wave entrainment and can induce altered states of consciousness.
Lucid dreams, altered states, deep relaxation, euphoria, increased
intuition, awareness, enhanced creativity, accelerated learning,
psychic abilities, elimination of insomnia and the symptoms of
stress, increased endorphin levels have been attributed to the use
of binaural beat audio technology. A technology that permits the
control of brainwave frequency patterns allowing the intentional
inducement of altered states.
This new technology, is based on binaural beat frequencies and their
effect on the sub cortical auditory system of the brain. After five
minutes, the resonant entrainment effect has induced vast areas of
the brain to resonate at the same frequency. The result is a
dominant brain wave pattern at the desired frequency.
The binaural beat brainwave entrainment technology combined with the
subliminal messaging encoders allows the professional user the most
advanced technology available to induce deep trance and affect
What Are Binaural Beats?.
Binaural beats are auditory brainstem responses which originate in
the superior olivary nucleus of each hemisphere. They result from
the interaction of two different auditory impulses, originating in
opposite ears, below 1000 Hz and which differ in frequency between
one and 30 Hz (Oster, 1973).
For example, if a pure tone of 400 Hz is presented to the right ear
and a pure tone of 410 Hz is presented simultaneously to the left
ear, an amplitude modulated standing wave of 10 Hz, the difference
between the two tones, is experienced as the two wave forms mesh in
and out of phase within the superior olivary nuclei.
This binaural beat is not heard in the ordinary sense of the word
(the human range of hearing is from 20-20,000 Hz). It is perceived
as an auditory beat and theoretically can be used to entrain
specific neural rhythms through the frequency-following response (FFR)--the
tendency for cortical potentials to entrain to or resonate at the
frequency of an external stimulus. Thus, it is theoretically
possible to utilize a specific binaural-beat frequency as a
consciousness management technique to entrain a specific cortical
Various Uses Of Audio With Embedded Binaural Beats.
Uses of audio with embedded binaural beats that are mixed with music
or various pink or background sound are diverse. They range from
relaxation, meditation, stress reduction, pain management, improved
sleep quality, decrease in sleep requirements, super learning,
enhanced creativity and intuition, remote viewing, telepathy, and
out-of-body experience and lucid dreaming. Audio embedded with
binaural beats is often combined with various meditation techniques,
as well as positive affirmations and visualization for best
The Discovery Of Binaural Beats.
Binaural beats were discovered in 1839 by a German experimenter, H.
W. Dove. The human ability to "hear" binaural beats appears to be
the result of evolutionary adaptation. Many evolved species can
detect binaural beats because of their brain structure.
The frequencies at which binaural beats can be detected change
depending upon the size of the species' cranium. In the human,
binaural beats can be detected when carrier waves are below
approximately 1000 Hz (Oster, 1973). Below 1000 Hz the wave length
of the signal is longer than the diameter of the human skull. Thus,
signals below 1000 Hz curve around the skull by diffraction.
The same effect can be observed with radio wave propagation.
Lower-frequency (longer wave length) radio waves (such as AM radio)
travel around the earth over and in between mountains and
structures. Higher-frequency (shorter wave length) radio waves (such
as FM radio, TV, and microwaves) travel in a straight line and can't
curve around the earth.
Mountains and structures block these high-frequency signals. Because
frequencies below 1000 Hz curve around the skull, incoming signals
below 1000 Hz are heard by both ears. But due to the distance
between the ears, the brain "hears" the inputs from the ears as out
of phase with each other. As the sound wave passes around the skull,
each ear gets a different portion of the wave. It is this waveform
phase difference that allows for accurate location of sounds below
Audio direction finding at higher frequencies is less accurate than
it is for frequencies below 1000 Hz. At 8000 Hz the pinna (external
ear) becomes effective as an aid to localization. In summary it's
the ability of the brain to detect a waveform phase difference is
what enables it to perceive binaural beats.
How Binaural Beats works on the brain.
When signals of two different frequencies are presented, one to each
ear, the brain detects phase differences between these signals.
"Under natural circumstances a detected phase difference would
provide directional information.
The brain processes this anomalous information differently when
these phase differences are heard with stereo headphones or
speakers. A perceptual integration of the two signals takes place,
producing the sensation of a third "beat" frequency. The difference
between the signals waxes and wanes as the two different input
frequencies mesh in and out of phase. As a result of these
constantly increasing and decreasing differences, an
amplitude-modulated standing wave-the binaural beat- is heard. The
binaural beat is perceived as a fluctuating rhythm at the frequency
of the difference between the two auditory inputs.
Evidence suggests that the binaural beats are generated in the
brainstem's superior olivary nucleus, the first site of
contralateral integration in the auditory system (Oster, 1973).
Studies also suggest that the frequency-following response
originates from the inferior colliculus (Smith, Marsh, & Brown,
1975)" (Owens & Atwater, 1995). This activity is conducted to the
cortex where it can be recorded by scalp electrodes.
Altered States of Consciousness.
Binaural beats can easily be heard at the low frequencies (< 30 Hz)
that are characteristic of the EEG spectrum (Oster, 1973). This
perceptual phenomenon of binaural beating and the objective
measurement of the frequency-following response (Hink, Kodera,
Yamada, Kaga, & Suzuki, 1980) suggest conditions which facilitate
entrainment of brain waves and altered states of consciousness.
There have been numerous anecdotal reports and a growing number of
research efforts reporting changes in consciousness associated with
binaural-beats. "The subjective effect of listening to binaural
beats may be relaxing or stimulating, depending on the frequency of
the binaural-beat stimulation" (Owens & Atwater, 1995). Binaural
beats in the delta (1 to 4 Hz) and theta (4 to 8 Hz) ranges have
been associated with reports of relaxed, meditative, and creative
states (Hiew, 1995), and used as an aid to falling asleep.
Binaural beats in the alpha frequencies (8 to 12 Hz) have increased
alpha brain waves (Foster, 1990) and binaural beats in the beta
frequencies (typically 16 to 24 Hz) have been associated with
reports of increased concentration or alertness (Monroe, 1985) and
improved memory (Kennerly, 1994).
Passively listening to binaural beats may not spontaneously propel
you into an altered state of consciousness. One's subjective
experience in response to binaural-beat stimulation may also be
influenced by a number of mediating factors. For example, the
willingness and ability of the listener to relax and focus attention
may contribute to binaural-beat effectiveness in inducing state
Synchronized brain waves.
Synchronized brain waves have long been associated with meditative
and hypnogogic states, and audio with embedded binaural beats has
the ability to induce and improve such states of consciousness. The
reason for this is physiological. Each ear is "hardwired" (so to
speak) to both hemispheres of the brain (Rosenzweig, 1961).
Each hemisphere has its own olivary nucleus (sound-processing
center) which receives signals from each ear. In keeping with this
physiological structure, when a binaural beat is perceived there are
actually two standing waves of equal amplitude and frequency
present, one in each hemisphere.
So, there are two separate standing waves entraining portions of
each hemisphere to the same frequency. The binaural beats appear to
contribute to the hemispheric synchronization evidenced in
meditative and hypnogogic states of consciousness. Brain function is
also enhanced through the increase of cross-collosal communication
between the left and right hemispheres of the brain.
What is the function of the various brainwaves?.
It is well known that the brain is an electrochemical organ;
researchers have speculated that a fully functioning brain can
generate as much as 10 watts of electrical power. Other more
conservative investigators calculate that if all 10 billion
interconnected nerve cells discharged at one time that a single
electrode placed on the human scalp would record something like five
millionths to 50 millionths of a volt. If you had enough scalps
hooked up you might be able to light a flashlight bulb.
Even though this electrical power is very limited, it does occur in
very specific ways that are characteristic of the human brain.
Electrical activity emanating from the brain is displayed in the
form of brainwaves. There are four categories of these brainwaves,
ranging from the most activity to the least activity. When the brain
is aroused and actively engaged in mental activities, it generates
beta waves. These beta waves are of relatively low amplitude, and
are the fastest of the four different brainwaves.
The frequency of beta waves ranges from 15 to 40 cycles a second.
Beta waves are characteristics of a strongly engaged mind. A person
in active conversation would be in beta. A debater would be in high
beta. A person making a speech, or a teacher, or a talk show host
would all be in beta when they are engaged in their work.
The nest brainwave category in order of frequency is alpha. Where
beta represented arousal, alpha represents non-arousal. Alpha
brainwaves are slower, and higher in amplitude. Their frequency
ranges from 9 to 14 cycles per second. A person who has complete a
task and sits down to rest is often in an alpha state. A person who
takes time out to reflect or meditate is usually in an alpha state.
A person who takes a break from a conference and walks in the garden
is often in an alpha state.
The next state, theta brainwaves, are typically of even greater
amplitude and slower frequency. This frequency range is normally
between 5 and 8 cycles per second. A person who has taken time off
from a task and begins to daydream is often in a theta brainwave
state. A person who is driving on a freeway, and discovers that they
can't recall the last five miles, is often in a theta state--induced
by the process of freeway driving. The repetitious nature of that
form of driving compared to a country road would differentiate a
theta state and a beta state in order to perform the driving task
Individuals who do a lot of freeway driving often get good ideas
during those periods when they are in theta. Individuals who run
outdoors often are in the state of mental relaxation that is slower
that alpha and when in theta, they are prone to a flow of ideas.
This can occur in the shower or in the tub or even while shaving or
brushing your hair. It is a state where tasks become so automatic
that you can mentally disengage from them. The ideation that can
take place during the theta state is often free flow and occurs
without censorship or guilt. It is typically a very positive mental
The final brainwave state is delta. Here the brainwaves are of the
greatest amplitude and slowest frequency. They typically center
around a range of 1.5 to 4 cycles per second. They never go down to
zero because that would mean that you were brain dead. But, deep
dreamless sleep would take you down to the lowest frequency.
Typically, 2 to 3 cycles per second.
When we go to bed and read for a few minutes before attempting to
sleep, we are likely to be in low beta. When we put the book down,
turn off the lights and close our eyes, our brainwaves will descend
from beta, to alpha, to theta and finally, when we fall asleep, to
It is a well known fact that humans dream in 90 minutes cycles. When
the delta brainwave frequencies increase into the frequency of theta
brainwaves, active dreaming takes place and often becomes more
experiential to the person. Typically, when this occurs, there is
rapid eye movement, which is characteristic of active dreaming. This
is called REM, and is a well known phenomenon.
When an individual awakes from a deep sleep in preparation for
getting up, their brainwave frequencies increase through the
different specific stages of brainwave activity. That is, they will
increase from delta to theta and then to alpha and finally, when the
alarm goes off, into beta. If that individual hits the snooze alarm
button, they will drop in frequency to a non-aroused state, or even
into theta, or sometimes fall back to sleep in delta.
During this awakening cycle, it is possible for individuals to stay
in the theta state for an extended period of say, five to 15
minutes--which would allow them to have a free flow of ideas about
yesterday's events or to contemplate the activities of the
forthcoming day. This time can be extremely productive and can be a
period of very meaningful and creative mental activity.
In summary, there are four brainwave states that range from the high
amplitude, low frequency delta to the low amplitude, high frequency
beta. These brainwave states range from deep dreamless sleep to high
arousal. The same four brainwave states are common to the human
species. Men, women, and children of all ages experience the same
characteristic brainwaves. They are consistent across cultures and
Research has shown that although one brainwave state may predominate
at any given time, depending on the activity level of the
individual, the remaining three brain states are present in the mix
of brainwaves at all times. In other words, while somebody is in an
aroused state and exhibiting a beta brainwave pattern, there also
exists in that person's brain a component of alpha, theta and delta,
even though these may be present only at the trace level.
You may try out different audible tones with the BTG/Subliminal
Messaging Encoder and see which ones work best for you. Altered
brain states, as mentioned above, applying a stimulus to the brain
will eventually bring the brain's state closer to the stimulus
frequency. The following describe some possible effects of this.
Note, however, that just passively listening to binaural beats does
not necessarily alter your state of consciousness. For example,
willingness and ability to relax and focus attention affects how
effective the binaural beat stimulus is for inducing state changes.
Helping in meditation. Meditation is essentially about willingly
being able to alter one's brain frequency to a desired state. While
mediators have traditionally used several years to learn the
techniques of meditation, you can now attain the same effect with
brainwave entrainment. No special training or great discipline is
Good meditation frequencies are in the alpha range, from 8Hz to
13Hz. When a certain brainwave state is experienced and practiced
over a period of time, the brain will "learn" the state change and
it will become easier to self-produce the desired Brainwave State at
Thus, using brainwave entrainment, you can expect to get some of its
effects later even without any entrainment. Reducing learning time.
The theta stage (4hz - 7Hz) has been found to increase learning
capabilities. In fact, children spend more time in theta stage than
adults do, which probably explains the accelerated learning
capabilities of children.
Alpha frequencies are also useful for learning purposes. You can
play language cassettes, subliminal tapes, etc. during an
entrainment session for a maximum effect. Reducing sleep need some
people have found that half an hour a day of the Theta stage can
replace up to 4 hours of sleep.
Treatment of certain mental diseases, Brainwave entrainment is used
in treatment of depression, low self-esteem, attention deficit
disorder, drug and alcohol addiction and autism, to name a few.
Brainwave entrainment has also been found helpful in alleviating
headaches and migraines. Some users have also reported increases in
their sex drive because of brainwave entrainment.
