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.
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.
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.
