#hemisync

When signals of two different frequencies are presented through headphones, one frequency to one ear and another frequency to the other ear, the signals do not heterodyne nor produce a beat frequency oscillation. What does happen is the brain detects phase differences between these signals. Under natural circumstances a detected phase difference would provide directional information to the higher centres of the brain.

No one ever hears binaural beats. The sound processing centres of the brain only think something is heard. Additionally, the production of an amplitude modulated standing wave is dependent on the ability of the electrochemical cellular structure of brain tissues to resonate. Brain tissues do resonate as evidenced by the manifestation of electromagnetic brain waves. These brain waves are generally confined to frequencies below about 30hz. The same is true for binaural beats. Experimental subjects do not report "hearing" binaural beats above about 30hz.

The term Hemisync was chosen because many of the states of consciousness available through this technology are the result of wave forms of equal amplitude and frequency in both hemispheres of the brain.

Under laboratory conditions many subjects were tested for their responses to binaural beats. Records were kept as to the effect each binaural beat frequency had on these subjects. Then binaural beats were mixed and records were again kept on the subjects' responses. After many months (in some cases, years), test results began to show population-wide similar responses to specific mixes of binaural beats, which laid the foundation for what is now called Hemisync. The individual binaural beats within these unique mixes entrained separate areas of the brain to different frequencies, effectively producing discrete states of consciousness. In the case of the state of consciousness coined Focus 10 (mind awake, body asleep.) for example, the cerebellum, which works below the level of consciousness and deals with muscles and body functions, must be entrained to a delta frequency. Under these conditions (a delta brain wave within the cerebellum) the body is asleep. The "mind awake" half of Focus 10 is achieved by entraining the cerebral cortex to a low beta frequency. The subject's exposure to these individual binaural beats is timed, introducing the delta cerebellum signal first and later mixing in the low beta cerebral cortex signal. The mixing of these two binaural beats produces a complex Hemisync signal.
