How Isochronic Tones Work

Isochronic Tones – The Most Effective Form Of Audio Brainwave Entrainment

Isochronic Tones without musiclsochronic tones are created in a completely different way to Binaural Beats. Instead of two different tones being combined together, just a single repeating tone is used.

The beat is created by turning the tone on and off at regular intervals. This is also referred to as Amplitude Entrainment.

As you can see from diagram below, Isochronic Tones are significantly more obvious and stronger. The resulting entrainment effect is much more powerful than Binaural Beats.

Isochronic Tones Mixed With Music

Brainwave entrainment can be mixed with normal music and white noise very effectively, which can really enhance the user experience and make the beats more pleasant and relaxing to to listen to.

The image below shows an Isochronic Tone that has been mixed with music. Although the individual pulses are not separated as clearly, the resulting entrainment effect is still very effective on the brain.


How Brainwave Entrainment Works

Your brain continually produces electrical activity, even when you are asleep. Neurologists found that this activity can be recorded in the form of brainwave patterns, also known as ‘brainwaves'.

Many scientific studies have shown that the brainwave activity in the brain can be influenced and corrected when it is stimulated with specific beats and tones. This process is known as ‘Brainwave Entrainment', and can be extremely effective when used correctly.

How Binaural Beats Work

Binaural Beats are created by sending a different tone into each ear. The tones are mixed together ‘inside' your head by your brain, resulting in a pulse also called a ‘beat'. So as an example, you might send a frequency of 200hz into your left ear, and 190hz into the right. This would create a beating tone in your brain at 10hz.

The lower of the two tones is called the ‘carrier' and the higher one the ‘offset'.

The beat you hear is actually created inside your head, not externally. This is because your brain creates the beat after working out the differences from each ear.

Because of how Binaural Beats work, you always have to listen to them with headphones on, so that each ear can receive a different frequency. If you listen to the same Binaural Beat audio without headphones, in most cases you will hardly be able to detect a beat at all, because your ears will be able to hear both frequencies at once and the effect is lost.

This can be a drawback with Binaural Beats, because it's not always practical or desired to listen to entrainment with headphones on.

How a typical Binaural Beat would look in your brain:


The fluctuation in the wave pattern is what creates the resulting beat.

Isochronic Tones

Because Binaural Beats were the first breakthrough in audio brainwave entrainment, they are still the most well known.  But there is another more modern and up to date form of brain entrainment which called Isochronic Tones.

Isochronic tones are the most modern form of audio brainwave entrainment.  They create a much more obvious and distinctive beat, which results in a much more powerful and effective form of entrainment.


Theta Brainwaves Frequency Guide

The Theta brainwave state ranges between 4 – 8 Hz, and is usually experienced during light sleep or extreme relaxation.

Deep Relaxation and Meditation

With practice and experience, it is possible to reach the Theta state through meditation, but you can speed up this process with Mind Amend's brain entrainment programs.

Gamma Brainwaves Frequency Guide

Gamma waves function at the highest and fastest range in the brain at 40+ Hz.

Inspired Thinking and  Increased Concentration

The Gamma state is experienced during super high levels of focus, and periods of peak cognitive functioning.

Stimulating Gamma waves can also help induce an intense state of energy, and mind alertness.

Delta Brainwaves Frequency Guide

Delta waves are the slowest of all brainwave frequencies and range between 1 – 4 Hz.  If your dominant brainwave frequency is Delta you are in a deep sleep.

For Healing and Sleep

It's during this deep Delta state that your body does it's best healing and replenishes itself.  Which is why it's so important to try and get a great nights sleep.

Brainwave Frequencies Guide

Your Different Mental States, Measured By Your Brainwave Frequency

Through the advancement of neurological research, we are now able to accurately identify what frequency ranges our brainwaves are in, during certain mental states.

For example:

  • Gamma 40+ Hz is experienced during extreme alertness, high energy and times of intense focus.
  • Beta' 12hz – 40hz, is the most common mental state for most of us when we are awake during the day.
  • The ‘Alpha' range is between 8hz – 12hz, and in this state we are awake but relaxed, and not processing much information.
  • During light sleep or deep relaxation we are usually in between the 4hz to 8hz range. Also known as ‘Theta'.
  • When we are in a deep sleep, our brainwave frequency is usually very low, between 0 hz to 4hz which is also referred to as ‘Delta'.

With this knowledge and more in depth research, we are now able to develop brainwave entrainment programs, to match the frequency range of our desired mental state, and produce brainwave synchronization.

Beta Brainwaves Frequency Guide

Beta 12hz – 40hz, is the most common mental state for most of us when we are awake during the day. However, many people don't experience enough Beta activity in their brain, which can cause emotional or mental disorders such as depression, ADD and insomnia.

Brain Health Booster

Stimulating Beta activity can improve emotional stability, concentration, alertness and energy levels.
