Hemi-Sync’s binaural beat CDs can help you experience enhanced mental, physical, and emotional states.
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.
