The brain has two hemispheres that operate somewhat independently from one another. The two hemispheric structures of the brain are connected by a large nerve, called the corpus callosum, which sends information back and forth between the two sides of the brain. In most people, the left hemisphere controls language, logical thinking, and analytic processes and the right side contains the centers for emotion, intuition, and non-linear creative thinking.
Hi Jason, thanks for all the uploads to youtube. I’ve been using them in work recently to help me concentrate and relax. I like the music tracks that you’ve chosen to overlay the tones. A couple of times in the last 2 weeks I’ve experienced the wavy pulse like sound, similar to the tones in my left ear. I wasn’t listening to tracks at the time or that day. It doesn’t last but it feels a bit strange. I wondered if I might have been listening to the tracks too loudly and that it was almost like a type of tinnitus. I’m curious to know if anyone has been in touch with you in the past to say they’ve had a similar experience?

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.
Thanks Lorita. There hasn’t been any isochronic tones research that I’m aware of, for anti-aging, fat loss or attracting people, or any significant anecdotal feedback. You could combine positive affirmations or hypnosis scripts with isochronic tones to try and change habits and that could help with fat loss or build confidence to attract people. But it would be the affirmations and hypnosis doing most of the work, the isochronic tones would just be used to help relax the listener and put them in a more suggestible state. I don’t believe isochronic tones can affect those things, without being used in combination with some kind of vocal mental programming.
I was diagnosed with “acute high anxiety, major clinical depression,and ptsd” 16 years ago. I have clinically addressed these disorders with a number of medications, which none have helped. I am so lucky I have found this simple easy to practice method of practice, that I have found these beats and tones so essential that I indoctrinated them into my daily life, and have come to the realization, that someday very soon I will awake and will not suffer from these burdens these disorders ever again.
When blended with musical sounds, brainwave entrainment frequencies induce specific states of mind, which are the result of those brainwaves, delivering them in pleasing and relaxing audio tracts for use with and without stereo headphones. For example, alpha and theta waves, because they exist at the borders between conscious and unconscious thought, are especially rich and useful for tapping into and stimulating subconscious processes.

To get a full answer you should really get in touch with the owner of the app, because it does really depend on how their track is constructed and how they intend it to work. I have one 50-minute sleep track which takes you down into delta (http://www.mindamend.com/shop/sleeping-and-dreaming/sleep-induction-isochronic-tones/) and that is designed to just get you to sleep, so you just let play until the end. If you played that track on repeat it might make you jump and wake you up, as the track begins at a higher frequency. I have another 8-hour sleep track which is meant to be played all throughout the night (http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/). So it does depend on the individual track you are using.

If anybody would like to look over the scientific evidence concerning brainwave entrainment and isochronic tones, I’ve done a lot of research over the years which I’ve collected at the PubMed website of NCBI – a branch of the National Institute of Health – that provides access to a large library of medical journal articles. I’ve made my list public so you can look through the journal articles that were published concerning this topic. Here’s the link: http://www.ncbi.nlm.nih.gov/sites/myncbi/1tmDFOl0XtyA4/collections/51531796/public/. Most of the collection only gives access to abstracts or summaries unless you’re at some kind of educational institution that has a subscription to the particular journal that article is in, but I actually find abstracts really helpful. So have at it, read away. And if your psychiatrist/therapist thinks you’re nuts for feeling better after listening to isochronic tones, just whip out your 82-page collection of scientific journal abstracts written by her peers and give it to her to read. 🙂
There is a certain point where the promised benefits of brainwave entrainment become more esoteric, and based on internal, subjective experience of oneself.  A few examples would be that listening to brainwave entrainment on a regular basis helps to increase one’s self-awareness, or that it increases mental “sharpness”, or helps to heal emotional trauma and increase your tolerance of stress and negative emotion. 
My name is [name removed] and I purchased the full Equisync set about 2 years ago and I’m very happy with this product. I still feel and notice euphoric and life changing effects to this day and I’m so grateful for this fact. I continue to follow the research on this subject and know that as science and technology advances a more quality product can be produced.
In simplest form, they are an audio technology which are used for (safe) brainwave entrainment. Our subconscious mind operates, throughout the day and night, in various brainwave state frequencies, measured in cycles per second (Hz) These frequencies range from the slowest (Delta) frequencies experienced in deep, dreamless sleep and in deep meditation where your conscious-awareness is fully detached, to the fastest (Gamma) frequencies associated to stimulating flow states, high-level thinking and information processing. There are actually 5 known brainwave state frequencies each having their own set of unique characteristics:
The specific benefits and claims from this technology are often disputed and considered scientifically questionable. One problem is that there are few experiments that have utilized brainwave entrainment for the purpose of treating a specific psychological ailment (e.g. insomnia). And the experiments that have been conducted are largely backed by corporations that sell the software; hence it could be speculated that there are conflicts of interest.

With so many thoughts begging for your attention each day, it’s hard to believe that most of them are the same ones you had yesterday. Actually, many psychologists who have studied the thought processes associated with our thinking patterns would agree that, on average, 90% of the thoughts that we become aware of throughout the day are the same thoughts that we have already experienced, over and over again. The reason we are so prone to repetitive thinking is because the brain is always … [Read more...]

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.
I have been using the Equisync CDs at least 24 minutes 5 days a week. It instantly relaxes me, helps get rid of headaches and even hiccups! I have a stressful job and it helps prevent anxiety; I have not had a chance to check my blood pressure but I feel calmer. I have used other products before but I like the Equisync CDs much better; it is deeper and more relaxing.
  It's like gaining a new level of clarity... understanding.... wisdom. When you're able to artistically and logically render solutions to problems... when you can objectively and subjectively evaluate opportunities and their innate qualities... when you can read people and empathetically understand them... you're given a foresight that others simply lack.
Most programs start at a work/life busy brain Beta frequency of twenty light flashes per second (20Hz) and slowly ramp them down to Alpha (relaxation and meditation) at 8-12 HZ, Theta (deep relaxation and dreaming) at 4-8 Hz) and Delta (dreamless deep relaxation) of .5-4Hz. We have taken measurements at Mass General with state of the art EEG equipment and have seen a slowing of the brain waves from Beta to Theta in two minutes and complete brain wave harmonization in the left, right, anterior, posterior and occipital regions of the brain.
These sounds in these musical tracks are presented through monaural beats, binaural beats, isochronic tones, or a mixture involving combinations of all three of these modalities, described in detail below. Choose alpha brainwave tracks for calming anxiety and relaxing body and mind, and choose theta tracks for help in getting to sleep and for bringing hidden feelings to the surface. Some people also report out-of-body type experiences when in theta brainwave states.
Have you ever found yourself in a tough situation where you couldn’t think of a way out? If you have, it might be due to a lack of Alpha brainwave activity. It’s been proven that increased production of these brainwaves allows people to deal with and solve problems at a faster rate and with far fewer difficulties. This is made possible thanks to the brainwave’s ability to get rid of “mental blocks” that prevent solving the problem at hand.
Because of others observing all of this I have been able to send you several customers and will very likely be sending you more… I am part of a large spiritual community and this would help tremendously in spreading the word of EquiSync. I also believe your product would be of great benefit to Hospice and nursing home patients of which there is a very large number here in Florida -aka- God’s waiting room.

After the illness, I returned to school and found out that I couldn’t understand what the teacher was saying. Or what people were saying to me in general. Then I had difficulty comprehending math (which I was excellent at before). Then my reaction time just CRASHED. I was also classified by new teachers as “flighty”, “in a dream world”, “not mentally engaged”, as my brain began to stay in a state of sleepy-but-unable-to-sleep mode.

Basically, one frequency of sound plays through one speaker/headphone and a different sound frequency plays in the other speaker/headphone. With these two different frequencies playing in each ear separately, but at the same time, your brain automatically tries to make up the difference in this frequency range and therefore is gently brought into a new, desired brainwave state as described above. An example of this effect would be a 100Hz frequency playing in your left ear and a 105Hz frequency playing in your right ear. Your brain, over several minutes, distinguishes the slight difference in frequencies and automatically adjusts its brainwave state to match this difference – being 5Hz in this example and therefore putting your brainwave into a Theta state. Pretty cool huh?!
My question is using the Alpha Isochronic Tones- it says not to use while driving or working. But what about listening while you study? I’m studying for a rather difficult exam and I’m looking for something to use while actually learning/reading the material for focus, concentration & comprehension. Thanks! And are the Alpha tones the best tones for this?
However, if you are looking to do something more practical, like improve your mental sharpness, overcome attention issues, succeed at work, be more productive, you may want audios that target more of the alpha and beta ranges, and are created to put you in peak performance states of mind. In this case, a program like our Effortless Overachiever Bundle would be much more practical and helpful for you.
Attention and learning ability has been suggested to improve as a result of beta stimulation protocols. Research has shown that beta waves tend to be deficient among those who have learning disabilities and/or attention deficits. Other research with photic stimulation determined that stimulating 14 Hz and alternating it with 22 Hz over several sessions produced significant GPA improvements.

Thanks, this was the kind of article I was looking for. I most have gotten over excited as I read a post about a guy who had major success with 40hz binaural beats. I wanted to make my own experiment, but I see now that I will need to continue my research and gather more background information. Maybe one should have his physiology examined? In order to have a professional opinion on whether or not it will be altered or damaged by use of brainwave entrainment (Maybe you happen to be a very vulnerable individual). Getting trustworthy guidance from an experienced source would also be nice 🙂
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.
Brainwave entrainment can enhance physical, emotional and mental healing. As a matter of fact, medical experts make use of different frequencies to assist patients who suffer from depression, attention deficit disorders, alcoholism, autism, poor self esteem as well as drug addiction. You could also make use of brainwave frequencies to alleviate migraines and headaches.
1) Theta Music Meditation from Unexplainable Store. Yep, you guessed it, this is a meditation MP3... with music. Boom. This is a nice, simple, powerful 20 minute session and (like all my recommendations) guaranteed 100% to work every time. Find yourself drifting away with this awesome recording, and start to reap the benefits of your underused theta brain waves. Simple and understated, my favourite.
It may be that you had the volume too loud, but I would expect you to hear the effects of that straight after you’ve stopped listening, not on a day you haven’t used them. It might be something similar to muscle memory, where you suddenly remembered the sound and sensations it gives you as if you were hearing it again. I don’t know how long you’ve been using this type of thing for, but maybe it’s something that will settle down and disappear once you become more accustomed to the sound.
Delta brainwaves, resonating at 1Hz-4Hz, usually only occur in the deeper levels of sleep. It is even uncommon to access Delta brainwaves through meditation, unless one is very advanced, or is using brainwave entrainment. Even while using brainwave entrainment technology, it will take some mental training and practice to be able to maintain conscious awareness and not fall asleep.

Not only do certain brain wave rhythms get strengthened as a result of entrainment, but a dominant frequency band results in a different state of awareness. Those that have used a quality brainwave entrainment product can vouch for the fact that their perception is altered by their brain waves. Not only could this be due to brainwave changes, but it may be a result of increased interhemispheric communication.


Hi Pajaro. It is difficult to pinpoint exactly why and they probably didn’t want to make assumptions without conclusive evidence. Do you suffer from ADD? Or do you struggle to focus? The reason I ask is because of this: “Peak performers’ decrease Delta waves when high focus and peak performance is required. However, most individuals diagnosed with Attention Deficit Disorder, naturally increase rather than decrease Delta activity when trying to focus. The inappropriate Delta response often severely restricts the ability to focus and maintain attention. It is as if the brain is locked into a perpetual drowsy state”. This extract… Read more »

Lucid dreaming: A lucid dream is considered a dream that a person is aware of and often able to consciously manipulate.  Many have alleged that using brainwave entrainment technology makes it easier to experience a lucid dream.  Scientists have studied this phenomenon and noticed that beta frequencies within the range of 13 to 19 Hz tend to be generated to keep the person conscious.  Additionally there is significant increased activity in the parietal lobes of the brain, which allows an individual to stay conscious.
Discovered by Austrian Psychiatrist Hans Berger in 1908, Alpha brainwaves cycle 8 to 13 times per second, a good bit slower than beta brainwaves. While considered a part of a group of brainwaves, the Alpha brainwave has one distinct trait that makes it stand out from its siblings – it appears and disappears while going through our brain. Sometimes alpha waves are present, sometimes they are not. The disappearance of the Alpha brainwave usually occurs when someone is asleep or experiences heightened emotions such as fear or anger. This brainwave only appears whenever a person is awake and relaxed, a one-of-a-kind distinction among other types of brainwaves. 
First of all thank you for your amazing website, I have a question regarding these matters, I can make both binaural beats and isochronic tones for myself but I doubt for low frequencies states (Theta and Delta) which one is better? Because I searched a lot and saw that binaural beats are better for low frequencies and for high frequencies (Beta Gamma Lambda….) isochronic tones are more effective. Also, for Alpha states some said isochronic and other said binaural.
Binaural beats were the first method discovered for brainwave entrainment and works by delivering tones of different audible frequencies to the two ears with the difference in frequency between the two tones being the frequency of entrainment. The difference in frequency between the two tones must be less than 30 hertz, and this resulting frequency is called a beat or the target frequency, and it is processed in a brain region called the olivary body. When listening to such tones with stereo headphones, the two hemispheres of the brain become synchronized at the target frequency.
While the physiological and psychological processes being uncovered by brain science in the study of brainwaves is sometimes complex and still being investigated, certain basic principles are well-established, easily understood, and helpful for achieving the most effectively use of brainwave entrainment when seeking relaxation, improved sleep, lowering of anxiety, or other goals. This important background information and scientific knowledge presented here includes: 
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.

In the 1980s, a researcher in Japan, Tsuyoshi Inouye described how light stimulation creates synchronization of brain hemispheres. Since then, other researchers have detailed the positive effects of hemispheric synchronization including a 1984 study by researcher Dr. Gene W. Brockopp stating that hemispheric synchronization resulted in improved intellectual functioning as well as improvements in long-term memory, and these effects are cumulative over time.
The functional role of neural oscillations is still not fully understood;[6] however they have been shown to correlate with emotional responses, motor control, and a number of cognitive functions including information transfer, perception, and memory.[7][8][9] Specifically, neural oscillations, in particular theta activity, are extensively linked to memory function, and coupling between theta and gamma activity is considered to be vital for memory functions, including episodic memory.[10][11][12]
