Hemi-Sync® Audio Technology

Hemi-Sync® research activities and technology

The patented Hemi-Sync® process has been refined with over 50 years of research and development. Ongoing experimentation, data collection and analysis are conducted at The Monroe Institute's laboratory facilities to demonstrate the correlation 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 hemisync 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 HemiSync® extensively.

The Hemi-Sync® process is internationally acclaimed. Thousands of people have journeyed from around the world to attend The Monroe Institute's life-enhancing residential programs. These programs, conducted at the Institute's training facilities in Virginia, are dedicated to developing, exploring, and applying expanded states of consciousness using the extraordinary Hemi-Sync® sound technologies.

Change of brain waves

On the following picture you can see change in the character of brain waves.

When listening to recordings with Hemi-Sync® through stereo headphones or speakers (on the imaginary line in axis of your ears), your brain responds by producing a third sound (called a binaural beat) that encourages the desired brain wave activity.

HemiSync® helps you safely alter your brain waves with multi-layered patterns of sound frequencies. When you hear these through stereo headphones or speakers, your brain responds by producing a third sound (called a binaural beat) that encourages the desired brain wave activity.

This is how binaural beating works

A sound played in the left ear is heard as a single tone.
A sound played in the right ear is also heard as a single tone.
When played together the vibrato perceived is called binaural beating.

What Hemi-Sync® can do for you?

HemiSync® can help you experience enhanced mental, physical, and emotional states, by combining verbal guidance, music, pink sound and/or other audio effects with the binaural beats. The particular elements for each recording are carefully selected and integrated with the appropriate HemiSync® sound frequencies to enhance the desired effect.

Professional Papers and Research

Hemi-Sync® research has been ongoing for over four decades, and today is concentrated in three distinct areas:

  • Clinical application by members of The Monroe Institute®'s Professional Division. This might involve, for example, studying Metamusic® as an aid for reducing anxiety in a dentist's waiting room.
  • Independent clinical or technical research by universities or other institutions on the mechanisms underlying the effectiveness of the Hemi-Sync® process. This research may be published in peer-reviewed journals and may include masters thesis and doctoral dissertations.
  • Applied research in The Monroe Institute laboratory to improve and expand HemiSync® applications. The Institute uses conventional scientific procedures whenever feasible but does not limit itself to such processes.
