The CIA Files: Hemi-Sync – Increase Brain Activity!

The global awakening of human consciousness!


In 1975, Monroe registered the first of several patents concerning audio techniques designed to stimulate brain functions until the left and right hemispheres became synchronized. Monroe held that this state, dubbed Hemi-Sync (hemispherical synchronization), could be used to promote mental well-being or to trigger an altered state of consciousness. Monroe’s concept was based on an earlier hypothesis known as binaural beats and has since been expanded upon a commercial basis by the self-help industry.

Hemi-Sync is a trademarked brand name for a patented process used to create audio patterns containing binaural beats, which are commercialized in the form of audio CDs. Interstate Industries Inc., created by Hemi-Sync founder Robert Monroe, is the owner of the Hemi-Sync technology.

Hemi-Sync is short for Hemispheric Synchronization, also known as brainwave synchronization. Monroe indicated that the technique synchronizes the two hemispheres of one’s brain, thereby creating a ‘frequency-following response’ designed to evoke certain effects. Hemi-Sync has been used for many purposes, including relaxation and sleep induction, learning and memory aids, helping those with physical and mental difficulties, and reaching altered states of consciousness through the use of sound.

The technique involves using sound waves to entrain brain waves. Wearing headphones, Monroe claimed that brains respond by producing a third sound (called binaural beats) that encouraged various brainwave activity changes.[19][24] In 2002, a University of Virginia presentation at the Society for Psychophysiologial Research examined Monroe’s claim. The presentation demonstrated that EEG changes did not occur when the standard electromagnetic headphones of Monroe’s setup were replaced by air conduction headphones, which were connected to a remote transducer by rubber tubes. This suggests that the basis for the entrainment effects is electromagnetic rather than acoustical.

Replicated, double-blind, randomized trials on anesthetized patients have found Hemi-Sync effective as a partial replacement for fentanyl during surgery.  A similar study found it ineffective at replacing propofol, however. source

The Monroe Institute


The Monroe Institute is the world leader in human consciousness exploration. Founded in the early 1970s as an educational and research organization by Robert A. Monroe, our experiential programs are offered on our main campus in Faber, Virginia USA as well as 12 additional countries and online.

Using specially designed binaural beat audio-guided technology, originally developed by Bob Monroe, you will learn valuable tools to explore, navigate and use non-physical aspects of your own higher consciousness.

Join the tens of thousands of people who have attended our retreats and awaken your consciousness to discover a new more compassionate perspective about yourself and others—what and who you are and why you are here.

Born October 30, 1915, Bob spent his childhood in Kentucky and Indiana. After graduating Ohio State University in 1937 with a BA in English, he worked as a writer and director at two Ohio radio stations. Two years later he moved to New York and expanded his broadcasting career, producing and directing weekly radio programs and eventually forming his own radio production company.

In 1956 his production company set up a research and development division to study the effects of various sound patterns on human consciousness, including the feasibility of learning during sleep. Monroe often used himself as a test subject for this research and in 1958 he began experiencing what he described as an “out-of-body experience,” the term popularized by Charles T. Tart, PhD, a leader in the area of consciousness studies. These spontaneous experiences altered the course of Monroe’s life and the direction of his professional efforts.

Throughout the next twenty years, Monroe continued to explore, research, and teach others about practical methods of attaining and using expanded consciousness. He developed a series of multi-day workshops, built a campus for education and research, and created a portfolio of binaural beat audio-guided technology. He chronicled his early explorations with a reporter’s objectivity and eye for detail in a groundbreaking book, “Journeys Out of the Body,” which was published in 1971.

In 1985 he wrote a second book, titled “Far Journeys,” which expanded upon his personal investigations of nonphysical reality. In 1994 he followed suit with a third book, “Ultimate Journey,” which explores basic truths about the meaning and purpose of life and what lies beyond the limits of our physical world. Monroe died in 1995, at the age of seventy-nine. His legacy continues today and has touched the lives of literally millions of people all around the world.
