A Quick Introduction To Hemi-Sync®. 
                
The Hemi-Sync process has been developed and used for 40 years as part of a sound therapy approach to facilitating beneficial brain wave states. This amazing technology developed by Robert Monroe, a sound engineer and businessman from the United States, has also been used successfully in consciousness expansion and personal growth applications. After years of research and refinement,The Gateway Experience set has emerged as the most extensive assemblage of exercises mixed with clinically proven and scientifically developed Hemi-Sync®, for the extraordinary task of exploring realms beyond the physical body.

Here's How it Works:
Hemi-Sync is a scientifically and clinically proven audio-guidance process that works quite simply by sending different sounds (tones) to each ear by stereo headphones. This process is perfectly safe and non-intrusive, which also means no subliminal messages are used. Any verbal cues are clearly stated and understood.

The two hemispheres of the brain then act in unison to “hear” a third signal--(A Binaural Beat)the difference between the two tones. This is not an actual sound, but an electrical signal that can only be perceived within the brain when both brain hemispheres are working together.

The result is a focused, whole-brain state known as hemispheric synchronization or “Hemi-Sync," an optimal condition for improving human performance, or heightening awareness.

In its more practical applications, specific combinations of Hemi-Sync signals, for example, has helped users achieve laser-like focus and concentration. Different Hemi-Sync signals mixed in the variety of single Hemi-Sync self-help titles have encouraged profound relaxation, expanded awareness, or other desired states for its listeners.
