Hemi-Sync is a patented, scientifically and clinically proven audio-guidance technology refined with over 40 years of research. Researchers learned that specific sound patterns could lead the brain to various states of consciousness, ranging from deep relaxation or sleep to expanded awareness and other 'extraordinary' states. The audio-guidance process works through the generation of complex, multilayered audio signals, which act together to create a resonance that is reflected in unique brain-wave forms characteristic of specific states of consciousness. 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. Different Hemi-Sync signals are used to facilitate deep relaxation, focused attention, or other desired states. As an analogy, lasers produce focused, coherent light. Hemi-Sync produces a focused coherent mind, which is an optional condition for improving human performance. Music, with subtle sound effects are conbined with Hemi-Sync signals to strengthen their effectiveness. These recordings do not contain subliminal messages. You are always in control. Aeoliah's music is a perfect fit for the Hemi-Sync Program because it facilitates higher states of consciousness that are sustained by reosnanct harmonics which are healing, uplifting and transforming.
