The patented Hemi-Sync® process has been refined with over 40 years of research and development. Ongoing experimentation, data collection and analysis are conducted at The Monroe Institute’s laboratory facilities to demonstrate the correlations between subjective experiential reports and objective electronic measurements.

Such research is indispensable in revealing the influence of specific Hemi-Sync® sound patterns on consciousness. Over the years, these efforts have resulted in the development of scores of individual products for specific applications such as focused attention, stress management, meditation, sleep enhancement, and pain management, to name a few.

Thanks to the cooperation of notable medical institutions and universities, the scientifically and clinically proven Hemi-Sync® technology continues to be the focus of a variety of specialized research projects. In addition, many therapists, physicians, educators, and other professionals use Hemi-Sync® extensively.
