Over 40 years ago Robert A Monroe, a then successful radio producer, began a research & development organization to study the effects of sound on human consciousness Ancient cultures used the natural power of sound to safely influence states of consciousness (the Shamans drum) in religious ceremonies & to promote psychological & physical health. Today the idea that auditory stimulation can effect your consciousness is widely accepted.
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 head-phones 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.There are two main types of Hemi-Sync recording Metamusic & Mindfood

Metamusic is more than music. From soul-stirring New Age to the timeless popularity of classical, Metamusic combines delightful musical selections with renowned Hemi-Sync sound technologies to entertain and benefit the listener. Many titles feature special blends of Alpha, Delta, and Theta frequencies to slow excess mental activity in order to facilitate meditation or support relaxation. Other selections feature a predominance of Beta frequencies for focus and concentration or Delta frequencies for sleep enhancement.

Mind Food CDs do not contain music. These selections incorporate verbal guidance and/or subtle sound effects along with specially blended Hemi-Sync frequencies and sound patterns designed to help you achieve and sustain synchronized brain-wave activity in both hemispheres of your brain. As with Metamusic recordings, Mind Food selections are available for a wide variety of uses ranging from meditation or focused attention to stress reduction and sleep enhancement or for other practical everyday applications.


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.

Robert Monroe's work inspired an entire industry of mind/brain products. 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.The patented Hemi-Sync® process has been refined with over 40 years of research and development. Ongoing experimentation, data collection and analysis are conducted at The Monroe Institute's laboratory facilities to demonstrate the correlation between subjective experiential reports and objective electronic measurements.
