Mindspa is the first meditation program to use binaural beats in a specific frequency range, where the effects are greatest, to synchronize the brain and to relax the body. This magical frequency range is called the Gamma (~40Hz) range, associated with peak concentration and creativity. This is also the specific frequency of the brain that experienced Buddhist monks experience during intense meditation.
A binaural beat is a natural frequency in the brain, created when slightly different modified sound waves are sent to each ear. So the brain imagines a third tone to compensate for the difference, which stimulates rapid communication between distant regions of the brain and increases whole-brain activity.
