Hemi-Sync

Hemi-Sync is a trademarked brand name for a process developed at the Monroe Institute, used to create audio patterns containing binaural beats, which are commercialized in the form of audio CDs. Other companies have also created and marketed products based on the concept of binaural beats such as Holosync by the Centerpointe Institute.

The technique involves using sound waves to entrain brain waves. Wearing headphones, Monroe claimed that brains respond by producing a third sound (called binaural beats) that encouraged various brainwave activity changes. More »
