The Monroe Institute, founded by Robert A. Monroe, is internationally known for its work with audio sound patterns that can have dramatic effects on states of consciousness. Monroe observed, during his early research, that certain sounds create a Frequency Following Response in the electrical activity of the brain.

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.

After decades of research, and thousands of lab sessions, the extraordinary Hemi-Sync® process remains unparalleled in its ability to assist us in harnessing our human potential.
