Those observations led to some remarkable findings dealing with the very nature of human consciousness. Researchers learned specific sounds could be blended and sequenced to gently lead the brain to various states ranging from deep relaxation or sleep to expanded states of awareness and other “extraordinary” states. This compelling research became the foundation of a noninvasive and easy-to-use “audio-guidance” technology known as “Hemi-Sync.”

The audio-guidance process works quite simply by sending different sounds (tones) to each ear by stereo headphones. The two hemispheres of the brain then act in unison to “hear” a third signal-the difference between the two tones. This is not an actual sound, but an electrical signal that can only be perceived within the brain by both brain hemispheres working together. The result is a focused, whole-brain state known as hemispheric synchronization, or “Hemi-Sync”-an optimal condition for improving human performance.

Specific combinations of Hemi-Sync signals, for example, can help individuals achieve laserlike focus and concentration. Different Hemi-Sync signals are used to facilitate profound relaxation, expanded awareness or other desired states. Depending on the intended goals, music, verbal guidance or subtle sound effects are combined with Hemi-Sync to strengthen its effectiveness. Users remain in total control as these recordings do not contain subliminal messages.

Hemispheric synchronization does occur naturally in daily life but typically only for random, brief periods of time. Hemi-Sync can assist individuals in achieving and sustaining this highly productive, coherent, brain-wave state.
