It is believed that the binaural beat originates in the superior olivary nucleus which is part of the
brain stem. The binaural beat is related to the ability to locate the source of sound and track them.
Studies of rhythmicity have provided insight into the understanding of the brain processing temporal
information. It has been proven that auditory rhythms are able to entrain the motor responses into
states of stable synchronization which are either above or below the conscious perception.
The tracking of temporal modulations is activated on the right prefrontal, anterior cingulate and
intraparietal regions as well as posterior cerebellar hemispheres. The activity of the binaural beat is
recorded by scalp electrodes as they are directed to the main cortex of the brain.
With the use of binaural beats you are able to control your moods and experience the positive
effects that have been researched as results of binaural beats. Here is a simple break down of the
main frequencies used in binaural beats and what their effects are:
Beta Brain Waves – 13 to 40 Hz – Thinking quickly, very active, very busy concentrating
Alpha Brain Waves – 7 to 13 Hz – Awake but relaxed
Theta Brain Waves – 4 to 7 Hz – Heavy meditation, dreams, lucid
Delta Waves – less than 4 Hz – Deep unconscious sleep, dreamless
The effects of binaural beats and the benefits of the binaural beats are directly related to the
frequency range that the brain produces when two similar beats of different frequencies are played
into each ear. When the binaural beat is integrated with other sensory information techniques or
social psychological conditioning tools and an educational curriculum the person can access a variety
of beneficial applications and altered states of consciousness. People who choose to use this sort of
therapy with binaural beats are placed in a restricted environment where they are subjected to a
combination of multiplexed audio binaural beats which are mixed with ‘pink sound’ and other
assorted sounds which are more natural.
The hissing sound from a television when a station has come to an end is what is referred to as pink
sound. When this sound is used in binaural beat therapy the sound is equalized to be suitable for
human hearing to create a more natural sound. The thalamus and cortex of the brain is where
information, including sounds, is interpreted and the suitable response is activated, this is also
where levels of attention and arousal are controlled.
Some of the most exciting results from binaural beat therapy have been the relief of mental fatigue.
This is because the brain modulates the levels of potassium and sodium which allow for the effective
transportation of chemicals, hormones and other information around the body. The brain becomes
unbalanced when it is in the beta wave state for too long; this causes the levels of potassium and
sodium to become unbalanced and causes the processing of neurological and functional to become
inefficient. With binaural beats you are able to reset the levels and ensure that your functionality is
always at its peak.
