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.
