What is Hemi-Sync®?

Hemi-Sync® is a trademarked, state-of-the-art audio technology based on the natural functioning of the brain that encourages coherent brainwave activity. Our brains produce waves or patterns of electrical activity.

Different patterns indicate different mental states, such as rest (occipital Alpha), deep sleep (central Delta), meditation (central and frontal Theta), physical activity (wide-spread Beta).

Hemi-Sync's audio binaural beats influence these brainwave patterns and in concert with other components of the Hemi-Sync® process provide experiences in focused states of consciousness.  

Used at The Monroe Institute, Hemi-Sync® becomes part of an entire learning process; a combination of multiplexed audio binaural beats and pink sound (or music), verbal suggestion, relaxation exercises, guided imagery, group dynamics, and an educational curriculum all carefully crafted to engender first-person experiences of focused states of consciousness.

Hemi-Sync® influences brainwave patterns and alters states of arousal. Hemi-Sync® programs provide participants with the opportunity to experience focused states of consciousness.   Hemi-Sync® does not employ the use of subliminal suggestions.

Hemi-Sync® is designed for listening through stereo headphones or properly placed stereo speakers. The versatility of Hemi-Sync® gives the basic technology an almost limitless range of applications for mental, physical, and emotional well-being. The technology simply and effectively allows you to involve your own total capabilities and direct them as you choose. It can be compared to a powerful software program that facilitates extraordinary levels of performance and productivity, guided by the intention and desire of the listener.

In addition to verbal instructions, this auditory-guidance process involves carefully constructed blends and sequences of stereo sound patterns designed to evoke beneficial brainwave states through neurological mechanisms. Right and left auditory input is combined in the brainstem's superior olivary nucleus and routed to the reticular formation that, in turn, uses neurotransmitters to initiate changes in neurological activity in the thalamus and cortex.
