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 HYPERLINK "javascript:sndReq('resonance');%20javascript:sndDos('blank');"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 rhythm.
resonant entrainment of oscillating systems is a well-understood principle within the physical sciences. if a tuning fork designed to produce a frequency of 440 Hz is struck (causing it to oscillate) and then brought into the vicinity of another 440 Hz tuning fork, the second tuning fork will begin to oscillate. the first tuning fork is said to have entrained the second or caused it to resonate.
the physics of entrainment apply to biosystems as well. of interest here are the electromagnetic brain waves. the electrochemical activity of the brain results in the production of electromagnetic wave forms which can be objectively measured with sensitive equipment. brain waves change frequencies based on neural activity within the brain. because neural activity is electrochemical, brain function can be modified through the introduction of specific chemicals (drugs), by altering the brain's electromagnetic environment through induction, or through resonant entrainment techniques.
