Isochronic tones are a form of brain wave entrainment which is similar to other forms of 
entrainment such as binaural beats. Isochronic tones are specific frequency of tone that is played at 
a specific interval to force the brain to react in the desired manner. The main difference between 
the binaural beats and the isochronic tones is that you do not need to use headphones to experience 
the benefits from isochronic tones. 
Isochronic tones have been specifically designed to produce the tone at an audible frequency for a 
specific period of time, for example, you will listen to an isochronic tone that is 800 Hz for a couple 
of seconds, and then have total silence for 10 seconds, only to have the tone repeat at the exact 
same frequency for the exact same period of time, creating a cycle of tone, silence, tone. The brain 
then reacts to this stimulation by focusing the dominant brain wave frequency on the frequency of 
the ‘beat’ which is created with the pulsating tone of the isochronic tones session. 
Many people prefer using isochronic tones as they are easier to listen to for extended periods of 
time and you do not have to worry about having a head set to use them, making them easier to 
listen to anywhere. 
There are a variety of mental and physical problems which can be relieved with the use of isochronic 
tones, these include but are not limited to depression, headaches, sleep disorders, and increasing 
serotonin levels within the body. 
Many people combine the use of isochronic tones with meditation or other self-improvement 
techniques to help them grow emotionally, mentally and spiritually. Isochronic tones are very 
effective in helping you to relax, which is one of the most important aspects of any meditation 
practice. 
Whether you have started becoming interested in isochronic tones because of their effects on your 
mind and body or because you heard someone say that they help with meditation, you still need to 
do your own research and find the isochronic tones which work for you. 
Different frequencies of different isochronic tones are designed to generate different responses 
from the brain and within the body, but because each human being is an individual with their own 
set of preferences, ideas and beliefs, what works for one individual will not necessarily work for the 
next one in the same manner. 
Isochronic tones are as effective as binaural beats, except that they do not require the use of 
headphones to be effective. When you ready to start looking for different isochronic tones to add to 
your daily routine or to aid you with our meditation, studies, relaxing or any other area of your life 
where you feel you could benefit from the use of isochronic tones it is important to try a variety of 
isochronic tones before making a decision on which tones are best for you.
