***NOTE: (Last one) Please do research on which brainwaves do what before just trying out the first track you find! Also read descriptions of what frequencies are being used in the track, so you know what you are training your brain to! (Example: You struggle with OCD and have some anxiety. You see a track titled “Clear, Focused Thinking” and you try it out w/o reading the description. You either do not experience anything or you end up with worse anxiety/headache than before. If you knew before starting, that your problems were caused by too much Beta wave activity in your brain and the track was all low Beta ramping up to high Beta – you would not listen to it!)
There's no doubt that brainwave entrainment audio is a great technology for anyone who is interested in encouraging altered states of consciousness and it certainly can help people to reach deeper states of relaxation than they might normally have access to. I myself will often listen to brainwave entrainment music in order to enhance my practice of meditation. But let’s keep a balanced perspective, put all the marketing hype to one side for a moment and acknowledge that there is no brainwave entrainment technology in this world that can make you meditate like a Zen monk “at the touch of a button”, despite what some might like you to believe. The mind is NOT a machine. It moves through various states of consciousness in an organic way and at a natural pace. We certainly can guide and accelerate that process with the use of brainwave entrainment audio, but we cannot control it with the same sort of specificity and immediacy as you might control the speed of the car you drive.
…I got curious about the Equisync II CDs and it was the 2nd track that started giving me some body signs that revealed me I was in the alpha state. I never practiced meditation before, however, I follow the Gurdjieff and Ouspensky teachings which, if you are not aware, tell us how to do quite the same thing as meditation in our everyday lives while performing our daily tasks. I also believe that Equisync II was more appropriate for me because my life is also dedicated to collective causes, my personal life is totally under control, but your CDs were able to relieve my severe depression after only 3 days of practicing, my chronic insomnia condition which had been lasting for over 27 years seemed to be finally healed. I am truly amazed, really.
The eyes of the participants were closed and the VFP goggles illuminated in alternative manner; first the right eye, then the left. The rate at which the photic stimulation was conducted ranged between 0.5 Hz and 50 Hz. Of the 50 patients with migraines, 49 considered their headache as having been “helped” by the stimulation and 36 noted that their headache had completely “stopped” from the VFP goggles.
Another general benefit of using brainwave entrainment in general is that it increases and promotes whole-brain functioning, meaning that the two hemispheres of the brain grow more connections and exchange information more easily. This can help more starkly rational people become more intuitive, and more airy-fairy people become more focused and logical.
I later learned that a Nobel Prize-winning scientist, Ilya Prigogine, had developed a theoretical model regarding the evolution of complex systems (like the human mind) that described these quantum leaps in awareness and brain-power I was experiencing—to a “T”—and explained why they happened! I read everything I could get my hands on about his work.
Gamma waves are the fastest brainwave frequency range. Gamma brain waves are believed to link and process information from all other parts of the brain. A high amount of gamma wave activity in the brain is associated with intelligence, compassion, focus and feelings of happiness. High levels of gamma brain waves have also been linked to improved memory and an increased sensitivity to sensory input. Low amounts of gamma brainwave activity have been linked to learning difficulties, poor memory and impaired mental processing.
The brain produces electrical signals. These signals change depending on what we are doing and what mental state we are in. For instance when we sleep these signals are different from when we are awake. This brain activity can be measured with EEG. It will output in Hz (Hertz - cycles per second) these electrical signals. The most dominant brainwaves will tell us what sort of state a person is in. The slower vibration (lower Hz), the more relaxed that individual is. Using audio technology we get the brain to start following the beats or pulses in a sound if done exactly right.
Thanks for the reply. I am now clearer on ‘what’ is heard. Can you expand or point me in direction ..a bit more about ‘pitch frequency’ and frequency spoken about and what exactly is the difference ..and how we use the higher pitch frequencies to ‘hear’ or become aware of them? Would you only pick up the low freq on a EEG?. sorry for being pedantic ..it still does not clear up split isochronics and possibly creating same situation as binaural beats..
There are primarily three ways to elicit the frequency following response through an audio: binaural beats, monaural beats, and isochronic tones.  Binaural beats was the first method to be discovered, and has been used since the 80’s, after being first made known and popular by Robert Monroe of the Monroe Institute (the institute is still around today, though Mr. Monroe has passed away).  Binaural beats basically work in this way: one specific frequency/beat is played in one ear, let’s say, 1115 hz., while one slightly different frequency is played in the other at the same time, let’s say, 1120 hz.  What the brain will naturally do while exposed to these two frequencies in either ear is create its own “phantom” beat, that is the difference between the two frequencies.  In this case, it would be 5 hz., which is the frequency of the theta brainwave state.  Therefore, your brain would be led into the theta state.  At the same time, your brain working to combine these frequencies also ends up synchronizing its two hemispheres, and functioning in a whole-brained fashion while the listener is using the audio.
Clinical testing of Brain Sync programs resulted in a record-breaking 87% success rate. They are offered to patients at America's most prestigious hospitals such as Sloan Kettering and Dana Farber Institutes. EEG studies conducted at Harvard Body Mind Medical School, and UCLA concluded that Kelly Howell's Brain Wave Audio Technology® prompts brain activity into extraordinary body-mind states. Vist our Research Findings page for a full list of articles from the Harvard Medical School, the U.S. National Institutes of Health and Psychology Today that concur: the benefits of guided meditation, binaural beats, brainwave entrainment and positive subliminal messaging are real and profound. To learn more see this article about brainwaves in Scientific American.
The phenomena of brainwave entrainment was first described in the scientific literature in 1973 by Gerald Oster in results published in an article in Scientific American entitled, “Auditory Beats in the Brain”. He showed that a specific brainwave could be induced when a person heard two separate, but closely related, sound frequencies, one in each ear. He discovered that when the frequencies heard by each ear differed by about 10 hertz, the brainwave pattern of the person hearing the sound would synchronize to the difference between the two frequencies. For example, if the person heard a 410 hertz sound in one ear and a 400 hertz sound in the other ear, their brainwaves would stabilize at the difference between the two, or 10 hertz. This technique is called binaural beats, and it is a fundamental principle of brainwave entrainment methods.
Gamma waves are the most recently discovered brainwave, a discovery made possible by digital EEG technology. Gamma is associated with the integration of information from different areas of the brain, and having a good memory is associated with having a certain baseline of 40 hertz gamma activity. Low gamma activity is associated with learning disabilities and poor memory.
Isochronic tones are basically just a single tone with the volume being turned on and off at regular intervals. When you apply the same effects to music or a noise, it’s usually referred to as amplitude entrainment effects (in Mind Workstation anyway). When you apply the on/off effect to music or noise it’s usually done by targeting a specific frequency range in the sound and only turning that part on/off, leaving the rest of the music/noise untouched. What that does is allow parts of the music/noise to play without being distorted/interrupted, making it sound more pleasant to listen to. It produces a kind of fluttering sound as I like to call it and you can adjust the level of intensity.
Back in 1839, Dr. Heinrich Wilhelm Dove, a Prussian physicist and meteorologist, discovered that when you introduce tones with certain frequencies into each ear, you could actually entrain the electrical patterns within the brain to resonate in very specific patterns, called brainwave states. The last two decades have seen an amazing amount of scientific interest in this world transforming field of study, laying the foundation for the hundreds of studies conducted since then, boosting the technology’s significance and importance immeasurably.
The pitch frequency measures and describes what a beat sounds like, i.e. does the isochronic beat have a deeper bass sound, or is it high pitched and sharper sounding? The beat waveform frequency describes how many times the beat is repeating per second, i.e. how fast it is beating. You don’t really need to concern yourself about the pitch frequency, as that doesn’t have a direct influence on brainwave entrainment and doesn’t play a part on the measurement on an EEG. I only mentioned it because you were referring to humans not being able to hear below 20Hz. I change the pitch frequency just to suit the mood of the track. For tracks that are to be relaxing, for meditation or sleep, I tend to use a lower pitch frequency so it sounds deeper and more relaxing and I never have that lower than 100Hz. For an energizing, high focus track I might use a more higher pitched 200Hz isochronic tone, because that is sharper sounding and less likely to make you feel sleepy. That’s all you really need to know about the pitch frequency.
Absolutely. Binaural beats were first discovered over 150 years ago, and their use in brainwave entrainment audio has been the subject of a great deal of scientific exploration over the last 35 years in particular. Millions of people use brainwave entrainment music to enhance their quality of life and to experience deep relaxation. In fact, brainwave entrainment technology is now used for more than just meditation. It is also used by a variety of practitioners and private users for improving self-confidence, stress relief, pain management, relaxation, improving and concentration and improving the quality of one's sleep. If you would like to read an objective third party report on binaural beats, please refer to this Wikipedia article.

Insomnia: Perhaps one of the most promising uses of brainwave entrainment technology is for those struggling with insomnia. While the technology is unlikely to provide a “cure” it may help those who have a high level of arousal or are “keyed-up” – reduce their level of internal arousal and sleep. Specifically insomnia that is induced by excess stress (e.g. beta activity) would likely benefit from slower wave stimulation (e.g. alpha activity) to aid the brain in transitioning into sleep.
How it works: Brain Wave synchronizes brainwaves with a specific frequency by sending two different audible frequencies to each ear, which, after being processed by the brain, are perceived as an inaudible low frequency beat matching the target brainwave frequency. Various states of mind are associated with different inaudible brainwave frequencies, ranging from an alert and focused state of mind to deeply relaxed, all the way to deep sleep, and can be induced with this technique.  Brain Wave recreates these frequencies using the most advanced multi-stage binaural sequences available, allowing your mind to relax and synchronize with your desired state. It achieves this using a unique process called progressive brainwave entrainment.
Isochronic tones have only been proven to have an effect while you are listening to them, that’s why you won’t find me claiming anywhere that there are potentially positive long-term effects. Once the tones stop, your brainwaves are no longer being stimulated by the sound and so they stop being in sync with the tone frequency. For you to think you are still feeling the effects after all this time and from such a short time listening to them, I think it may be linked to anxiety. I know that some people who are new to this type of thing can build up a strong feeling of anxiety, after worrying about the potential effects brought on by fear of the unknown. I suspect the problem may be psychological with you worrying about the potential effects and keep repeating the experience from memory in your head. When you keep going over the same thing in your head like that and worrying about it, it’s easy to then spot other potential side-effects like how your nostrils and body temp is feeling, then making links back to that experience and labelling that as the reason. I think the best way to overcome this is to realise that the side-effects you are mentioning are completely unrelated, so there is nothing to worry about. These tracks are literally listened to for millions of hours a month on YouTube across loads of channels. If the effects lasted for a long time people would just listen for 5 minutes and come back in a couple of weeks. But people keep coming back to listen because that’s the only way to feel the benefit and effects…while you are listening to them. If you are unable to stop thinking and worrying about this on our own, I recommend that you speak to your doctor about it or a specialist in dealing with anxiety issues. I hope that helps.

Hemispheric synchronization: Whether it’s optimal or suboptimal to operate in a state of hemispheric synchronization remains unknown. Some speculate there are numerous benefits of brain waves operating in “sync” as a result of entrainment. There may be an increased communication between the right and left hemisphere of the brain – which could improve certain functions. However, it is also important to realize that increased hemispheric synchronization may not be as beneficial as many have speculated.


Heart rate variability: A new study suggests that among those with low HRV (heart-rate variability), brainwave entrainment can increase HRV. Researchers studied individuals ages 20 to 70 and administered alpha brain stimulation. The alpha wave stimulation resulted in greater heart-rate variability. Since a low HRV is associated with early mortality and poor psychological and physical health, efforts made to increase it should be regarded as beneficial.
I personally have been experimenting with binaural beats – both in and out of the float tank – for the past year or so and they have quickly and easily become one of my favourite go-to “hacks” for helping me achieve a desired state of being. From listening to a specific track right before going to sleep which helps put my mind and body in a state of relaxation and recovery to, on the flip-side, listening to a track that helps prime my brain-state for creativity and focus right before I sit down to do some work – like writing this blog! They are also an enjoyable and effective asset to try out and experiment with while in the float tank. For the reasons mentioned above, as well as the sound frequencies can resonate a subtle but noticeable vibration in the tank, water and your body making for quite the unique floating experience!
In the average person, the activity of one brain hemisphere is dominant over the other, called brain lateralization. This hemispheric imbalance leads us to experience the world in a black and white way, perceiving separation over connectedness. When brainwave entrainment is used to synchronize brainwave activity in both hemispheres simultaneously, a person can more easily integrate information from all parts of the brain and solve problems with greater intelligence and sensitivity.
Beta is the most common brain wave pattern: Beta brainwaves are produced when we are wide awake, alert, active and engaged in mental activity, usually involving more the rational, reality-oriented left hemisphere of our brain. When beta wave activity becomes very intense, our brain hemispheres become less synchronised. Beta state is required to function properly in your everyday life.
They use a proprietary process of ‘3 point dynamic audio entrainment’ which means that they use both binaural beats and isochronic tones, layered together with another process called temporal entrainment (the stretching and compressing of sound waves in order to speed up or slow down the brain). This 3 pronged effect on your brainwaves is very powerful, so powerful they are currently in the process of trying to patent it.
I enjoy this one called: Cognition Enhancer For Clearer and Faster Thinking – Isochronic Tones (Electronic) … I seem to enjoy it. Any harm in just listening to this one every day for 30 minutes as a routine daily thing, just like brushing your teeth and making your bed. I would just use it at times when I’m working at my desk, maybe even reading the online news etc…Thoughts?
Every NeuralSync™ audio is recorded with full-range frequency sweeps that cycle rhythmically throughout the entire audio. The dynamics of the sweep are then additionally enhanced with simultaneous left-to-right channel crossing. Because of this augmentation, the effects are multiplied, the intensity is amplified and the brain is drawn into the mental state more consistently and powerfully than with the static methods of other protocols.
This is probably the most popular choice of frequency. The theta state is a state of tremendous stress relief. The benefits associated with theta level relaxation include improved concentration, reduced hyperactivity and improved memory. While in a state of theta relaxation, one’s blood pressure, breathing and heart rate all slow to a much more restful and healthy level that promotes natural healing. During theta relaxation one may also experience vivid flashes of mental imagery as the mind opens to memories or subconscious information that is not available to the conscious mind during the normal waking state. The theta state is a very deep state of relaxation that is excellent for deep hypnosis and mental programming.

I am one of the fortunate ones who received a free demo of your product. I do believe your product corrected damage to my brain from a childhood concussion. Immediately upon use, I became aware of sounds, drainage and even discomfort behind my right eye and the lower right side of my skull. This continued for a week of using the product daily. I was about to give up using the product when all discomfort stopped, and has not returned. I do believe your product should be used for childhood head trauma. Even though the brain is only bruised, a life can be altered immensely. I love my Equisync II and will use it daily and with confidence.

Relaxation: There is already evidence that brainwave entrainment helps improve relaxation. In studies analyzing short-term stress and anxiety, significant improvements were noted. This has been verified by other studies that suggest brainwave entrainment enhances muscle relaxation in biofeedback and can help with pain reduction and migraine headaches. The relaxation-induced response of entrainment may be responsible for a variety of the benefits.
While it may not be a perfect therapeutic option for treating certain psychological conditions, brainwave entrainment is yet another tool that warrants further testing and exploration. There is clear evidence that certain protocols may benefit human performance. Unfortunately nearly all of the research has been conducted by those who clearly are affiliated with those who manufacture brainwave entrainment products.
The authors concluded that preliminary evidence suggested that brainwave entrapment was an effective therapeutic tool, but further research was required. The evidence presented appeared to justify the recommendation for further research. In view of the lack of controlled evidence and problems with methodology and reporting in the review, the authors’ conclusions regarding efficacy did not appear reliable.
