Brainwave Entrainment & Hypnosis

What is Brainwave?

Our brain is made of billions of brain cells, called neurons. These neurons communicate with each other through electrical signals. This combination of electrical activity is often referred to as a “brainwave pattern” – because of the cyclic, or “wave-like” pattern of the signals.

These patterns have been given different names, depending on their frequencies, and the states of mind typically associated with those frequencies. Research has shown that specific brainwave patterns mean that you’re in a particular state.

That means our brainwave frequency can actually determine our state of mind. So, if we could change our brainwave patterns, we could actually reproduce that original state of mind.

What Is Brainwave Entrainment?

Putting two swinging pendulum clocks next to each other for a few hours, while they may initially rock out of sequence, they will soon synchronize and swing in-line with each other.

This phenomenon in the world of science is known as “entrainment.”

The same happens with the brain. If we can play a frequency to it, our brain will “entrain” to – or follow – that frequency. This is called brainwave entrainment.

In other words, if we “played” a 10Hz frequency to our brain, it would follow that frequency.

What Are Binaural Beats?

In 1839, a Prussian physicist and meteorologist known as Heinrich Wilhelm Dove uncovered that by playing two different frequencies in each ear, the difference between those frequencies is realized inside the head – a perceived sound, also known as a binaural beat.

For example, if we played 400Hz into the left ear, and 410Hz into the right ear, the difference of 10Hz is actually heard by the brain. In other words, he found a way of playing a really low frequency directly to the brain.  This discovery helps us to overcome the problem of humans can typically only hear between 20Hz and 20,000 Hz (20 kHz) where the frequencies for creativity and relaxation ranges from 4Hz to 40Hz. 

About Brainwave Entrainment

To understand how brainwave entrainment works a understanding about brainwaves will be helpful. The 4 most common brainwaves are beta (13 hz - 30 hz), alpha (8 hz - 12 hz), theta (4 hz - 8 hz), and delta (0.5 hz - 4 hz). Although all 4 brainwaves are active in the brain at all times, one of these patterns is usually dominant depending on whether you are busy, emotional, relaxing, sleeping etc. Your dominant brainwave pattern is responsible for your state of awareness at any given moment.

 Following is a brief description of the beta, alpha, theta, and delta brainwave states:

Beta waves (13 to 40 Hz ) - Beta is identified with active, busy or anxious thinking and active concentration.

Alpha waves (8 to 12 Hz ) - When we begin to relax or begin to get drowsy, but are still awake and conscious, when we are day dreaming, we are at the alpha level.

Theta waves (4 to 8 Hz) - When we are asleep and have dreams, and experience rapid eye movement (REM), and have hallucinations, and even when we experience deep meditation, we are at the theta level. When we lucid dream (this is when you are conscious while you are dreaming) we are at the theta level.

Delta waves (0.5 to 4 Hz) - Delta waves are usually associated with deep, slow brain activity found in deep sleep. Delta waves are experienced predominantly in newborn infants, as well as in healthy adults in deep rejuvenating sleep, or in very deep states of brain enhancing, emotional cleansing, bodily renewing meditation. 

Brainwave Entrainment: A Shortcut To Meditation

Wikipedia defines brainwave entrainment this way:

"Brainwave synchronization or "brainwave entrainment", is any practice that aims to cause brainwave frequency to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep). It depends upon a "frequency following" response, a naturally occurring phenomenon where the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. Such a stimulus may be aural, as in the case of binaural beats, monaural beats, and isochronic tones, or else visual, as with a dream-machine, a combination of the two with a mind machine, or even electromagnetic radiation."

The human ear can't hear lower frequencies within the 0.1 hz - 15 hz range. This is where brainwave entrainment can help. Binaural beats, for example, trick the nervous system into perceiving lower frequencies. For example, when you listen to a 200 hz tone in one ear, and a 210 hz tone in the other ear, the human nervous system will try to resolve the input from both ears and manufacture a "phantom" 10 Hz tone. This is the actual binaural beat.

Binaural beats are the most recognized form of brainwave entrainment. With binaural beats a slightly different tone is presented into each ear. The tones then combine in the brain to form a pulse or "beat". The pulse heard by the listener is actually the difference between the two tones. For example, if the left ear is given a tone at 200 hertz and the right ear is given a tone of 210 hertz, then the listener will hear a beat of 10 hertz. And the brain will entrain to that rhythm. By listening to a brainwave entrainment mp3 embedded with binaural beats designed with a 10 hz frequency relaxation will follow as your brain becomes "entrained" by the repititious rhythm of the binaural beats.

 What is Brain Entrainment?

Brain Entrainment is defined as the synchronization of two or more rhythmic cycles. The basic principles of brainwave entrainment are universal, dealing in chemistry, neurology, biology and quantum science.

When your brain is given a certain stimulus, through sound or other senses, it gives off an electrical charge as a response called a Cortical Evoked Response.

These two frequencies, when mixed together, result in a combined frequency which aligns your brain waves and inspires different states and ways of thinking. So these beats are produced in the brain and not from the ears.

 Your brain waves are controlling how you think and respond to every stimulus you are experiencing right now, and they are either aligned in a state of learning, relaxation or energy… or they could be totally ‘switched off’ in the other direction.




Dominant Frequencies


Control Your Life

 Everything you do has adominant frequency associated. When you are in a state of relaxation your brain waves have a certain frequency. When you are alert and driven they have a totally different frequency.

Check out the different frequencies and the result usually associated with it.

Frequency range


Usually associated with:

> 40 Hz

Gamma waves

Higher mental activity, including perception, problem solving, fear, and consciousness

13 – 40 Hz

Beta waves

Active, busy or anxious thinking and active concentration, arousal, cognition

7 – 13 Hz

Alpha waves

Relaxation (while awake), pre-sleep and pre-wake drowsiness

4 – 7 Hz

Theta waves

Dreams, deep meditation, REM sleep

< 4 Hz

Delta waves

Deep dreamless sleep, loss of body awareness

 Binaural Beats.

 Two tones at slightly different frequencies are presented separately, one to each of a subject’s ears, using stereo headphones.

A beating tone will be perceived, as if the two tones mixed naturally, out of the brain.
These two frequencies, when mixed together, result in a different frequency which aligns your brain waves into a different way of thinking. This is often called brainwave entrainment.

Here is a picture to explain a little better.
