In binaural beats, one frequency is presented to one ear, and another frequency is presented to the other ear. Headphones must be used when listening to binaural beats because of the way they work. The frequencies presented to each ear are processed by the brain, and the result is that the brain tunes itself to the difference between these two frequencies or beats. To illustrate this, say for example, that a pure tone of 200Hz is presented to the right ear, and a pure tone of 207Hz is presented to the left ear. The result is that the brain is tuned to 7Hz, which is the difference between the two frequencies being presented to each ear. And since 7Hz is just at the upper edge of the Theta range, this will have the effect of tuning the brain to the Theta frequency. Now the actual beat of 7Hz is not heard audibly by the ears. The human range of hearing is between 20 and 20,000Hz, and 7Hz falls below this range. So the brain simply receives the 7Hz signal and it is perceived as an auditory beat, though is not audibly heard by the ears. And because it is perceived by the brain in this way, it is easily able to tune itself to the frequency through the frequency following response.
Isochronic tones work in a similar way by making use of the frequency following response, but they do it differently to binaural beats. Whereas binaural beats use two different frequencies to produce a third frequency toentrain the brain to, isochronic tones work in an audible way. They present a frequency to the ears, and the brain entrains to this frequency. Because of this, it is not necessary for headphones to be worn when listening to isochronic tones.Because of the way they work, isochronic tones sound different to binaural beats. Isochronic tones make use of the silent gap between each tone to entrain the brain, so the sound is more of a beeping nature rather than a continuous audible tone that is heard by the ear. Essentially, they are just pure tones that are being turned on and off again quite rapidly. This is what creates the sound pulses. This method of producing the sound pulses creates quite a powerful effect on the brain.
Isochronic Tones vs Binaural Beats
So which one is better – isochronic tones or binaural beats? The answer is neither. They are simply two different methods of achieving the same end goal: brainwave entrainment. They sound different, and some people prefer one over the other. The reality is that both are extremely effective methods, and the only way you will know for sure which one you prefer is to try both of them out and notice your results. Some people will say that they are able to enter into brain states better using isochronic pulses, and others will say the very same thing about binaural beats. It’s simply a matter of personal preference. The primary advantage of isochronic tones over binaural beats is that headphones are not needed when listening to isochronic tones.
In addition, you can also mix binaural beats and isochronic tones for a potentially more powerful effect. When this is done, the brain is presented with both the inaudible and audible frequency to entrain to, and some say that this is more powerful. In some cases, it can be. The mixed tone, again, sounds different to either single tone on its own, and it will be a matter of preference as to which one works best for you. Try them all out and see what you like best!

The Magic of Brainwave Entrainment
Brainwave entrainment has been used successfully for many years to help people achieve greater states of awareness, calmness, inner peace, creativity, inspiration and motivation.
To understand how it works, let’s take a look at how the brain works. Each person’s brain operates at different frequencies depending on what the person happens to be doing at the time. The four main frequencies are Beta, Alpha, Theta and Delta.
Beta refers to normal, waking consciousness and is most likely the state you are in right now as you read these words. The frequency of your brain in Beta ranges between 13 to 40Hz.
This Beta state is what most of us are used to living our lives in most of the time. This is largely due to the way we are taught in school and how we are expected to perform in our jobs. It is a logical world of problem solving which calls for the use of the left hemisphere of the brain, and obviously, conscious awareness.
There are, however, some downsides to the Beta state. It is in the Beta state when you are likely to experience stress, depression, anxiety, irritability, fear, paranoia, nervousness and worry. Sound familiar? Normal, waking consciousness is not without its problems!
Alpha is one level down from Beta, and in the Alpha state, your mind is more relaxed. You might experience this state when you’ve been reading a good book for some time, listening to some relaxing music, or just chilling on your front porch with a cup of tea, watching the world go by. In short, Alpha is a relaxed state and in it your brain operates at between 7 and 13Hz.
The Alpha state has many advantages and affords you the opportunity to eliminate stress, feel more confident and happier, more calm and relaxed. It allows for the release of serotonin and endorphins, and quiets down the mind chatter so as to facilitate learning and creativity. Alpha is a hugely beneficial state for your brain to be in.
One more level down from Alpha, we encounter Theta. In the Theta state, your brain operates between 4 and 7Hz, so it’s slowed down even more. You’ve experienced Theta if you’ve lay in bed just after waking up, and you’re kind of still half asleep, half awake, dozing in and out of consciousness, balancing on the fine line between the two. As in the Alpha state, serotonin and endorphins are released, and you can expect to experience vivid visualisations and greater inspiration as you are more deeply connected with the subconscious mind.
Delta is another level down from Theta and in Delta, or deep sleep, your brain operates between 0 and 4Hz. The Delta state is associated with rejuvenation and healing, and is believed by many scientists to be the most beneficial brain state. Delta is deep, dreamless sleep which affords your brain and your body the opportunity to rest, repair and renew. It also facilitates a deeper connection to the subconscious mind and can permit very highly advanced awareness.
