Robert Allan Monroe, also known as Bob Monroe (October 30, 1915 – March 17, 1995), was a radio broadcasting executive who became known for his research into altered consciousness and founding The Monroe Institute. His 1971 book Journeys Out of the Body is credited with popularizing the term “out-of-body experience”.
Monroe achieved world-wide recognition as an explorer of human consciousness. His research, beginning in the 1950s, produced evidence that specific sound patterns have identifiable, beneficial effects on our capabilities. For example, certain combinations of frequencies appeared to enhance alertness; others to induce sleep; and still others to evoke expanded states of consciousness.
Assisted by specialists in psychology, medicine, biochemistry, psychiatry, electrical engineering, physics, and education, Robert Monroe developed Hemi-Sync, a patented audio technology that is claimed to facilitate enhanced performance.
