Interstate Industries, Inc., (d/b/a Hemi-Sync®),
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 achieved world-wide recognition as a ground-breaking visionary and explorer of human consciousness. His pioneering research, beginning in the 1950s, led to the discovery that specific sound patterns have identifiable, beneficial effects on our capabilities. For example, certain combinations of frequencies enhance alertness; others induce sleep; and still others evoke expanded states of consciousness.
Assisted by a broad base of specialists in psychology, medicine, biochemistry, psychiatry, electrical engineering, physics, and education, Robert Monroe developed Hemi-Sync®, a low-cost, patented audio technology that facilitates enhanced performance.
Monroe entered radio broadcasting soon after graduation from Ohio State University.
In the late 1940s, he opened his own program production organization in New York, and served as Vice President and member of the Board of Directors of the Mutual Broadcasting System network. He is listed in Who’s Who in America in the 1950s, and is the author of three books, Journeys Out of the Body, Far Journeys, and Ultimate Journey.
In 1953 Mr. Monroe formed RAM Enterprises, a corporation that produced network radio programs, as many as 28 programs monthly, principally in dramatic and popular quiz shows.
