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.
Various forms of brainwave entrainment and synchronization have been used in many different cultures for hundreds of years. Long before scientists were able to measure our brainwave patterns.
Lots of historical references show that our ancestors used drums and or chanting, to induce and experience different states of mind. Some cultures still use the same methods today.
A Naturally Occurring Synchronization Phenomena
This synchronization phenomenon is not just confined to our brainwaves; it’s universal and appears in chemistry, biology, neurology, pharmacology, medicine, astronomy and more.
- If you put a number of pendulum clocks on the wall and started them at different times, you will find that within a day or sooner, all of the pendulums will start to synchronize with each other in perfect unison.
- If you ever listen to an audience clapping, you will notice that if it goes on for a while, people will start to clap in tune with each other, without consciously thinking about it.
Here’s a video example of metronomes completely synchronizing together in under 2 minutes.
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 0hz to 4hz which is also referred to as ‘Delta’.
Brainwave Entrainment Methods
With this knowledge and more in-depth research, we are now able to develop audio brainwave entrainment programs, to match the frequency range of our desired mental state, and produce brainwave synchronization.
For the brain to be effectively entrained, every tone or beat has to produce an individual electrical imprint on the brain, called a ‘Cortical Evoked Response’. The stronger the beat, the stronger the entrainment effect.
Binaural Beats
The most well-known form of brainwave entrainment uses Binaural Beats.
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 – The Most Powerful Form Of Audio Entrainment
lsochronic tones are created in a completely different way to Binaural Beats. Instead of two different tones being combined together, just a single 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 the diagram below, Isochronic Tones are significantly more obvious and stronger. The resulting entrainment effect is much more powerful than Binaural Beats.
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.

Hi Sopan, if you Google ‘isochronic tones’, you’ll find lots of sources of information in addition to what I have on my own website. I’d also recommend the following resource: http://www.transparentcorp.com/research/.
Hi jason i’ve been listening to your mental workout mix and was curious are there any other tracks you would recommend to increase IQ and memory beyond…or are there any tracks you would recommend for advanced listeners? do the effects decline and are they permanent, what are you doing to keeping yourself innovative im sure you must have reached a new level having listened to isochronic tones for quite sometime…I have been listening to your tracks for the last 4 months I have noticed benefits. Just wanted to know what else you suggest for someone extremely driven and self motivated 🙂 thank you Jason!!
Hi Dave, the effects of isochronic tones and brainwave entrainment isn’t permanent, so any gains you make in performance do start to decline over time if you stop using it. But that’s not a bad thing, because on the flip side it would be bad if you experienced a negative result from using it and the effect ended up as permanent.
I like to compare exercising your brain to exercising your body. You can spend a month going down the gym to lose weight and get fit, but if you stop exercising and don’t eat well, you will start to gain weight and become less fit. Your brain works in a similar way. You need to give it plenty of mental exercise to maintain it at an optimum level. A good example of this is when ‘some people’ quickly deteriorate when they retire, because they suddenly stopped exercising their brain to a high level on a daily basis.
IQ is a hard thing to increase significantly once you reach a certain level, as the biggest gains are seen in those with a lower IQ.
In making isochronic tones tracks for a wider audience, it’s hard to make something that fits everyone perfectly, because we are all wired a little differently. While one frequency range is perfect for helping someone to really focus well, another person may respond even better to a range 3Hz higher, or even below. So although there are certain frequency ranges that are deemed as widely suitable for specific things, to progress further, it’s often about tweaking things and finding frequencies and ranges which suit you personally and then adjusting them as you progress.
If you are looking to take things to the next level, you might want to consider making your own tracks using Neuro Programmer 3 (go for the ‘Ultimate Edition’ so that you can edit the frequencies of the default sessions). They do a 2 week trial of the software, so you can have a play around with it for free without any obligation. I use the more advanced Mind Workstation Enterprise, but Neuro Programmer is much easier to learn how to use and a great place to start.
I hope that helps, Jason
can i hv a qs how u use it and do u listen all time a single track or u make variation plzzz let me knw hw u use it…. advanced thanxxx
How you use these tracks largely depends on what your goals are, and what you want to achieve from using them. A single track will help you in a specific way. If you listen to a meditation track it will help you to relax your mind and meditate better while listening to it. If you later want to boost your energy levels, you will need to use a different more appropriate track for increasing energy, which uses higher frequencies.
If your goal is to concentrate on one area like meditation, you could start by just using a single meditation track whenever you meditate. You could then add to your collection by getting a different background sound version for the same meditation product. The brainwave entrainment tones will work the same if you’ve chosen another track from the same product. Just the music will be different to give you some variety. Using different background sound versions of the same product, also helps prevent your brain from getting bored or too used to the same sound all the time.
In the meditation category there are different products, which target different frequencies. Generally speaking, the lower the frequency, the deeper the meditation experience. If you are new to meditation, you might start with one of the higher frequency alpha tracks. Then over time, graduate further down by trying the lower frequency tracks.
If you are trying to increase your focus and ability to concentrate while studying for example, you could start by using a single track from the ‘Study Focus’ product suite. You might decide that you need more intense focus, so you might listen to a ‘Peak Focus for Complex Tasks’ track.
So it’s about using the appropriate track at the time you want to feel that particular way. I have versions of all of my products on YouTube, so you can experiment with them for free first, to see what frequency sessions work best for you, before getting the MP3s.
Dear Mr. Lewis, I would like to inquire to where I could find your credentials and scientific sources? I find your content interesting and I want to believe what you are saying, however, without empirical evidence, it takes me a too big of a leap of faith, to trust your findings, let alone purchase any of your tracks. Thank you! Have a nice day! Yours sincerely.
Hi Martijn, my work and products are based on past scientific research and studies into brainwave entrainment. If you are new to the concept of brainwave entrainment you can find information on some of the research collated here: http://www.transparentcorp.com/research/. On a personal level, I first encountered brainwave entrainment with Binaural Beats many years ago, but I was quite sceptical at first and put it aside. I then came across Isochronic Tones from a different source a while later, and they gave me some new and unusual sensations in my brain that I hadn’t felt before. This piqued my interest and I quickly became fascinated in the technology. That was around 9 years ago now and I’ve been using, studying and creating brainwave entrainment sessions for myself and others ever since.
Hey Jason , I have heard that Isochronic Tones are used to balance the brain waves in left and the right brain .. & it helps to improve the cognitive abilities in children, and after hearing this music children between 5 – 15 can view/feel things blindfolded or we can also say that it opens 3rd Eye Chakra [Pineal body] .. Is it True ?
My second question is, could you please tell me the difference between Binaural beats and Isochronic Tones ?
eagerly waiting for your reply
Hi Avi, isochronic tones can certainly be used to help balance the brainwaves across both brain hemispheres. However, it’s not a case of all isochronic tones tracks will improve cognitive abilities, because it depends on what frequency range you listen to. My products that will help with cognition are in this section here: https://www.mindamend.com/intelligence-and-brain-power/.
With regard to opening the third eye and being able to view things blindfolded, I haven’t seen any evidence of that. It’s possible that someone reported experiencing that during a one-off meditation where isochronic tones were used, but I can’t honestly say that it could be repeated for most people, just by listening to isochronic tones. Not based on the current evidence.
I explain the differences between isochronic tones and binaural beats in the article above. To summarise the benefits, isochronic tones produce a much deeper waveform which creates a more distinct beat. This results in stronger stimulation of the brainwaves. ‘Standard’ isochronic tones tracks also don’t require headphones, but you always need them with binaural beats.
Hi Jason,
I have been using a variety of your products,(Study and Learning, Intelligence and brain power, sleeping and dreaming,) with very positive results. I have recently purchased some of the affirmations tracks. I have two questions. 1. Will listening to a track completely change the results. As I am often listening to Cognition enhancement up until the last minute before taking an exam? 2. Is it possible to over do it when listening to these tracks, if so, is it all tracks?
Thanks
Tim
Hi Tim, I’m pleased to hear you are seeing some positive results from my products. I’m afraid I’m not exactly clear on your first question. Are you asking if listening to Cognition Enhancer will completely change your exam results, compared to how you might do without it?
If you are listening to Cognition Enhancer just before an exam, it will help get your brain into a relaxed and focused mental state, with your left brain being a bit more dominant. This can be very helpful in an exam situation.
However, your brain could still enter a similar peak state on it’s own and you may still perform just as well without listening to the track. But as you know, sometimes we don’t always perform to our best abilities. The pressure of the exam can get to us, our minds go blank and the answers don’t seem to come, or we just have an off day and don’t seem to have the energy for it. What these tracks do is help to ensure your brain is in that peak mental state, when you need it to be.
You can over do it with most things and that includes brainwave entrainment. If you over do it you may start to feel a little groggy, possibly get a headache. In a similar way to how you might feel after pulling an all night study period. So it’s a good idea to monitor yourself and cut back or take a break from it if you start to feel any negative effects.
To Clarify My first question, what I meant to ask is, If I am unable to finish listening to a track completely, will it have a negative effect on performance. I am often somewhere in the middle of a track when I have to turn off my MP3 and pay attention to my professors. I guess I am wondering if I should try to time my listening to a track that will end just as class begins?
It depends on the track to some extent, because I have tracks like ‘Get in the Zone’ where it’s a slow build up to the main action in the last third of it. So for something like that you’d be missing the best part so to speak.
Cognition Enhancer moves through a repetitive frequency range cycle, going up and down through it in a wave like form. So because you’re not trying to reach a specific point or frequency, you could stop it half way through and that would be ok.
With Mental Workout which you also have, that builds up to 20Hz by 6 minutes, holds you there for most of the track, then brings you back down to 15Hz at the end. If you stopped while up at 20Hz that’s not really a bad thing, as you will gradually work your way down naturally anyway.
I’d say it’s more important to listen to the relaxation and meditation tracks all the way through, as they bring you back up to a more alert state at the end.
With the affirmations tracks, they bring you back up from the relaxed Theta state, to a more alert Beta in the last few minutes. So if you stopped one of those in the middle you’d still benefit from the affirmations you’d heard, you’d just take a little longer to get back up to a more alert state again, because you wouldn’t have the tones helping you to get there.
I hope I’ve explained things ok?
Thanks Jason. That does clear it up. I have another question. Will listening to a different type of track cancel the effects of listening to a previous track, for example listening to a procrastination affirmation track and then immediately listening to study focus or cognition tracks?
Yes it will to some extent, because you will be guiding your brainwaves to a completely different frequency range. With the tracks you mentioned, the procrastination track will have you deeply relaxed down in theta, and the other two tracks will move you up through alpha and into an alert and higher beta state.
I said to some extent, because in your example the procrastination track is more about the affirmations than the actual tones. The tones are used to get you into a relaxed and suggestible state, to make the affirmations more effective. So if you switched to a beta track after that one to wake you up a bit, that’s not necessarily a bad thing or combination, because you’ve effectively finished listening to all the affirmations and you are ready to move on.
I know some people combine lots of my tracks to fit in with various activities during the day. You have to consider how you want to feel at that particular time, when combining different tracks, and choose any follow on tracks to match that. If you’ve listened to a deep theta meditation track and want to prolong the experience and stay chilled out afterwards, it’s not a good time to play a beta track. But if you want to get yourself back up and alert after meditating, then some beta would be a good idea.
I hope that explains things ok?
Yes It does thanks

How long should a person wait between doing different tones?
There isn’t really any official guidelines on how long you should wait, before using a different tone frequency or track. It’s hard to give you a better answer without knowing how you are thinking about using the tones and what you want to use them for? As an example, if you are doing a study session all afternoon, you could potentially use a different beta/study track one after the other. People tend to use each track as an when they want to enter that particular mental state. So you could use a beta/study track, then when you take a break you could listen to an alpha track to calm and relax you, before returning back to using a beta track again when you resume studying.
hi jason,is there a dwell time that is optimal when listening to brain entrainment sessions.
There isn’t really an optimum time I could recommend because there are so many factors influencing that. From the feedback I get it varies a lot between different people. One person will say half an hour is more than they need, then someone else will listen for 3 hours straight. It can also depend on your mood. The best thing to do is try to stay self aware and adjust how long you listen depending on how you feel during each session. The main thing to consider is that it takes 5 or 6 minutes minimum for it to start working. So you should always listen for at least that long.
I have ADD and stereo headphones, as I can hear different sounds in each ear. However, my earphones are not marked left and right, so how can I tell I’m stimulating the proper side of my brain? Thank you.
The only way to tell if you are using it right is to somehow mark one or both sides of earphones so you know which is which. Otherwise, you’ll just be guessing. You can run a sound test to indicate which is which using this video https://www.youtube.com/watch?v=hTvJoYnpeRQ.
How long during a session might it take for entrainment to begin? I’ve read that it’s more effective to ramp up (or down) the frequency to more efficiently alter brainwaves. I’m trying to produce my own audio files, but I would like to know the duration for optimal effect. How long might it take, for example to transition from alpha to gamma? Ten minutes? Twenty? Thanks!
It usually takes around 5 to 6 minutes on average for brainwave activity to become entrained to the frequency of the beats/tones. It has long been commonly debated in the community about the best method to structure a session. I would expect it to take longer to become entrained to a frequency that is far away from your current mental state, which is why ramps starting from mid-range frequencies are commonly used.
Most seem to be in the camp favouring ramping up or down gradually to a target frequency. Usually starting from a low beta frequency range, where most people might be dominant when semi relaxed but fully awake during the daytime.
However, there is also many that prefer to start listing to the target frequency/range from the start, without any ramps. Unfortunately, there hasn’t been enough research yet to definitely say which method is best. Based on my own use and the feedback I’ve had I believe that using ramps at the beginning is more effective.
Im afraid I can’t give you a simple optimum rule to follow, for how long it takes someone to get from one mental state like alpha to gamma. I do it in lots of different ways, depending on the goal of the track. With some tracks I would do this quite slowly over an hour, maybe for a more intense focus study session. For a short high energy track I might ramp up from alpha to gamma in 10 to 15 minutes.
On the flip side, you can really take your time ramping down from low beta to theta over an hour for a deep relaxation track. But for an anxiety track, you might want to ramp down over the same range in half the time or less, to help reduce someone’s anxiety more quickly.
Hi Jason
I’ve taken medication for ADD since 2016 or 2017 perhaps.
The ADD/ADHD Intense Relief Session came into my YouTube menu this morning and I listen to it.
It’s encouraging how my brain reacted quickly within a few minutes. I’ve recently order CD’s from the Monroe Institute for meditation aids and other reasons.
I’m curious about how your product may compliments my efforts toward concentration and focus improvements.
I’d like to learn more and welcome your reply. Thank you.
Anthony
Hi Anthony,
My ADD/ADHD Intense Relief tracks aim to increase the dominant brainwave frequency in the left brain. It’s been shown that people with ADD/ADHD will often produce a higher amount of slow-wave theta activity, particularly in the left brain. So that track can help provide some balance.
I’m afraid I can’t compare it to what you might be using from Monroe Institute as I don’t know how their tracks are constructed. One thing I will say is that it may not be helpful to meditate too much down in the theta range because it’s likely that you may already be producing higher than average theta activity already.
