Hemi-Sync is an audio technology listened to with headphones or stereo speakers. It was developed more than 50 years ago by the nonprofit Monroe Institute in Virginia with which we are affiliated. Hemi-Sync is easily and successfully used for many purposes, including relaxation, meditation and sleep induction; learning, attention, memory and focus; helping those with ADD, depression and anxiety; reducing stress, and reaching states of expanded awareness for the purpose of personal development, spiritual development and self discovery.

Hemi-Sync utilizes what's known as a binaural beat, an "apparent" sound perceived by and originating in the brain stem created when two tones at slightly different frequencies are presented separately, one to each ear (as through headphones or stereo speakers when using Hemi-Sync). The difference between the two tones creates the sensation of hearing a third sound, the binaural beat.

When listening to Hemi-Sync, the brain, focusing on the binaural beat, transitions from operating from either a right or left brain dominance to a synchronized, holistic whole brain functioning, where both hemispheres of the brain work in concert and collaboration. This significantly more focused and coherent state is optimum for many things, including relaxation, meditation, learning, healing, self-discovery and significantly, for the development of human potential.

Extensively utilized by therapists, physicians, educators, researchers and other professionals, 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 and around the world at medical institutions and universities.
