About Us

Interstate Industries, Inc., (d/b/a Monroe Products), 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.

In 1956 the firm created a Research and Development division to study the effects of various sound patterns on human consciousness, including the sleep state. Monroe was especially attracted to the concept of sleep-learning. This was a natural direction to take, applying to this new area the audio production methods used in the firm’s commercial activity. The purpose was to find more constructive uses for such knowledge than was ordinarily available, and the results of this research have become internationally known.

In 1962 the company moved to Virginia, and a few years later changed the corporate name to Monroe Industries. In this location it became active in radio station ownership, cable television, and later in the production and sale of audio cassettes. These cassettes were practical expressions of the discoveries made in the earlier and ongoing corporate research program.

In 1985 the company officially changed its name, once again, to Interstate Industries, Inc. This reflected Monroe’s analogy of how the use of Hemi-Sync® serves as a ramp from the “local road” to the “interstate” in allowing us to go full steam ahead in the exploration of consciousness, avoiding all of the stops and starts.

The research subsidiary was divested and established as an independent non-profit organization, The Monroe Institute®, later in 1985. Interstate Industries, Inc. remains a privately-held company, now doing business as Monroe Products®.

Robert Monroe’s contributions as the guiding force behind the entire program of development have been supported for more than 50 years by many specialists who continue their participation to this day. Hemi-Sync® continues its mission under the direction of its President, A. J. Honeycutt (Monroe’s stepson), and Garrett Stevens, the Company’s Chairman.
