Audio Technologies


Hemi-Sync® helps you safely alter your brain waves with multi-layered patterns of sound frequencies. 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 brain wave activity.

How Binaural Beats Work

  • A sound played in the left ear is heard as a single tone
  • A sound played in the right ear is also heard as a single tone
  • When played together the vibrato perceived is called binaural beating

What Does This Mean For You?

Hemi-Sync® can help you experience enhanced mental, physical, and emotional states, by combining verbal guidance, music, pink sound and/or other audio effects with the binaural beats. The particular elements for each recording are carefully selected and integrated with the appropriate Hemi-Sync® sound frequencies to enhance the desired effect.

It All Happens In The Brain

The brain controls all body activities, ranging from heart rate and breathing to emotion, learning, and memory. It is even thought to influence the immune system’s response to disease. It sets humans apart from all other species by allowing us to achieve scientific breakthroughs, composing masterpieces of literature, art, and music. The brain is what makes us human. The extent of the brain’s capabilities is unknown; it is the most complex living structure known in the universe.

The brain is divided into two hemispheres—left and right. The left hemisphere has been linked with verbal skills, rational, logical, and analytical thinking. The right hemisphere has been linked with visual/spatial skills, emotion, musical aptitude, intuition, and imaginative thought. There is a reason why we have two hemispheres: they are both necessary and complementary, and they function best when they are functioning together.

It is well known that the brain is an electrochemical organ; researchers have speculated that a fully functioning brain can generate as much as 10 watts of electrical power. Even though this electrical power is very limited, it does occur in very specific ways that are characteristic of the human brain. Electrical activity emanating from the brain is displayed in the form of brain waves.

Brain Waves And The Various States Of Consciousness

There are four basic categories of brain waves:
Beta, Alpha, Theta and Delta.

Our brains are always generating Beta, Alpha, Theta and Delta beats at the same time. When we say a person is in a Beta, Alpha, Theta or Delta state, it only means that is the strongest signal being detected at that time.

Beta brain waves are the fastest frequencies ranging from 14 cycles per second up to 38 cycles per second. Beta is your normal thinking state, your active external awareness and thought process. Without Beta you would not be able to function in the outside world.

Alpha brain waves are the brain waves of relaxed detached awareness, visualization, sensory imagery and light reverie. Ranging between about 9 cycles per second and 14 cycles per second, Alpha is the gateway to meditation and provides a bridge between the conscious and the subconscious mind.

Theta brain waves are the subconscious mind. Ranging from about 4 cycles per second up to 8 cycles per second, Theta is present in dreaming sleep and provides the experience of deep meditation when you meditate. Theta also contains the storehouse of creative inspiration and is where you often have your spiritual connection. Theta provides the “peak” in the peak experience.

Delta brain waves are the unconscious mind, the deep sleep state, ranging from about 4 cycles per second down to 0.5 cycles per second. When present in combination with other waves in a waking state, Delta acts as a form of radar – seeking out information – reaching out to understand on the deepest unconscious level things that we can’t understand through the thought process. Delta provides intuition, empathetic attunement, and instinctual insight. It is also the brain wave most often associated with energy healing.
