The audio phenomenon known as binaural beating can be used to access altered states of consciousness. This is done through a process in which individuals in an environment of restricted stimulation willfully focus attention on a combination of multiplexed audio binaural beats that are mixed with music, pink sound’, and/or assorted natural sounds.
In most cases the process also includes breathing exercises, guided relaxation, affirmation, and visualization. The binaural-beat element of the process appears to be associated with an electroencephalographic (EEG) frequency-following response in the brain.
Many studies have demonstrated the presence of a frequency-following response to auditory stimuli, recorded at the vertex of the human brain (top of the head).
This EEG activity was termed “frequency-following response” because its period (cycles per second) corresponds to the fundamental frequency of the stimulus . Stated plainly, if the audio stimulus is 40 Hz the resulting measured EEG will show a 40 Hz frequency following response using appropriate time-domain averaging protocols.
Binaural- beat stimulation, coupled with the effects of the other procedures within the process outlined above, appears to regulate neuronal activity and encourage access to propitious mental states.
The effectiveness of binaural beats in engendering state changes is supported by the consistent reports of thousands
of users, as well as the documentation of physiological changes associated with its use.
