Refined with over 50 years of research and development, and supported by numerous independent studies, reports, and articles, the patented Hemi-Sync® technology has been scientifically and clinically proven to be effective. This unique audio-guidance process works through the generation of complex, multi-layered audio signals, which act together to create a resonance that is reflected in unique brainwave forms characteristic of specific states of consciousness. 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 brainwave activity. The result is a focused, whole-brain state known as hemispheric synchronization, or Hemi-Sync®, where the left and right hemispheres are working together in a state of coherence.
