It is a course that covers six months, after each month you move onto the next level of the program. The levels start off with the eye-opening Transcendence and move on to the literally mind expanding levels of Neptune’s Cave and Fusion. With each level you complete, your ability to solve problems and deal with stress goes through the roof, and you will feel a deep sense of emotional bliss.
This music encourages a state of alpha relaxation. The alpha state is a pleasant state of relaxed alertness. It’s a state that many people experience when they are waking up in the morning or when they are just beginning to drift off to sleep at night. While in a state of alpha relaxation, the mind is quite clear and receptive to information, learning is accelerated and one’s sense of creativity is enhanced. The mind is also very open to positive suggestions during this state.
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.
No matter what you use: USE it. At least for a couple weeks.  And have realistic expectations...  Brainwave Entrainment is not some pill or quick solution (even if there are some sessions that usually give almost immediate results e.g. for sleep induction or pain relief), it is a tool that requires training and works best in combination with good breathing / meditation techniques.
“Binaural beats are not very noticeable because the modulation depth (the difference between loud and quiet) is 3 db, a two-to-one ratio. (Isochronic tones and mono beats easily have 50 db difference between loud and quiet, which is a 100,00-to-1 ratio). This means that binaural beats are unlikely to produce an significant entrainment because they don’t activate the thalamus.”
Alpha (12hz – 8hz) – Awake, but deeply relaxed. Simply closing your eyes will produce alpha brainwaves. This category is associated with daydreaming, visualization, imagination, light meditation. Brainwave expert Anna Wise called the alpha range the bridge between beta and theta. (More information can be found in Wise’ book The High-Performance Mind)
Please feel free to browse through the reviews in the navigation bar, as I have personally tested each and every product listed for an extended amount of time.  Also, do check out the brainwave entrainment audios and bundles we offer as well. Only the best products have even been able to make it onto this site. Rest assured that the products you are reading up are the “cream of the crop” as far as brainwave entrainment audio quality, and overall effectiveness.

“The great neuroscientist W. Gray Walter carried out a series of experiments in the late forties and fifties in which he used an electronic stroboscopic device in combination with EEG equipment to send rhythmic light flashes into the eyes of the subjects at frequencies ranging from ten to twenty five flashes per second. He was startled to find that the flickering seemed to alter the brain-wave activity of the whole cortex instead of just the areas associated with vision. Wrote Walter, “The rhythmic series of flashes appear to be breaking down some of the physiologic barriers between different regions of the brain. This means the stimulus of flicker received by the visual projection area of the cortex was breaking bounds— its ripples were overflowing into other areas.”
Monaural beats have similarities to binaural beats, but the two separate frequencies are delivered through a pulse pattern and mixed before they reach the listeners ears, resulting in the advantage of being audible without stereo headphones. However, using stereo headphones intensifies the effectiveness of monaural beats and is recommended for the best effect. 
Hi Et, In all the feedback and studies I’ve read and looked into over the years, I’ve seen lots of feedback from people talking about how they don’t like the sound of the tones, or they find them irritating in some way. Unfortunately, there doesn’t seem to be any particular reason why one person likes it and the next doesn’t. It’s a bit like normal music, one person’s sweet symphony is another person pneumatic drill. It’s common for people to find it weird and maybe annoying at first, which is how I felt in the beginning. But usually after a few listens you can start to get used to it and appreciate the sound, and especially the feeling it gives you. Personally, I think it can help if you try to embrace the sound, psychologically speaking beforehand. It can also help to have the sound playing at a very low volume, to begin with, then building it up as you get more used to it.
The objectives and inclusion criteria of the review were clear. Relevant sources were searched for studies, although the restriction to published studies in English meant that the review was prone to publication and language biases. The authors did not state whether steps were taken to minimise the risk of bias and error in the processes of study selection and data extraction (for example, by having more than one reviewer independently make decisions). The authors mentioned which studies were blinded, but it did not appear that study validity was systematically assessed, which made it difficult to judge the reliability of the review findings. The decision to combine studies by narrative synthesis appeared appropriate given the strong clinical heterogeneity between the studies, but the authors failed to quantify the size or statistical significance of the findings reported. The evidence presented appeared to justify the authors’ conclusions that further research was justified, but in view of the dearth of good-quality evidence and problems with methodology and reporting in the review, the conclusions regarding efficacy did not appear reliable.
Different people have different requirements when it comes to frequency changes in the music and it's quite impossible for us to anticipate them all. We would need to produce so many different variants of all our music productions that it would be impractical to manage and confusing for our customers. For example, if we were to start raising the frequency from theta up to alpha between the 50-60 minute mark of a piece of music, this would be useless to someone who used the music for a guided meditation that was only 45 minutes long. In the early stages of the development of our brainwave entrainment music we had so many different requests from different people that we could only opt for the simplest solution, which is to use a consistent frequency throughout. It might not be the absolute "perfect ideal", but this is still a very effective technique and the feedback we've received on our brainwave entrainment music has always been exceptionally positive.
Theta waves have a frequency between 4 and 7.5 hertz, making them slower than more wakeful alpha but faster than the dreamless slumber of delta. Theta brainwaves are the frequencies of nighttime dreams and REM sleep when the brain goes through bursts of activity and eye movement. People also experience theta waves in a state of light sleep, deep relaxation, during meditation and prayer, and when daydreaming. Theta waves produce an experience of inward wakefulness where we become disengaged from the outside world while engaging in inner activity. At the lower frequencies of theta, sleeping states are experienced, and at the higher range of frequency, awake relaxed states are experienced. 

You’ve probably heard people talk about the power of “positive thinking.” While some might tell you that it’s based on faith or strong belief, research has shown that there’s a third ingredient that helps you get that frame of mind – Alpha brainwaves. The rhythm produced by this brainwave – especially those that hit the frequency of 10 Hz – is said to help in the enhancement of one’s mood and thoughts, enabling one to experience and enjoy a positive state of mind.
This music encourages a state of delta relaxation. Delta brainwaves are most prevalent during deep, dreamless sleep. The delta state is a mostly unconscious state that is essential to one’s physical, emotional, psychological and spiritual wellbeing. People who are able to achieve a state of delta relaxation through meditation will sometimes describe spiritual encounters and out of body experiences. The delta state is perfect for inducing profound spiritual experiences, healing and deep subconscious repatterning. Delta frequency brainwave entrainment music is also a fantastic cure for insomnia.
According to both observation and research, after a series of brainwave entrainment practices, the brain learns how to state change. This enables you to achieve certain brainwave effects in the absence of entertainment. Additionally, research shows that children are usually in the Theta stage and this in itself could provide a detailed explanation for their ability to learn fast and remember what they have learned. We can take advantage of this effect and use Alpha and Theta waves to reduce learning time in adults.
The brain is composed of millions of specialized cells called neurons. Neurons send signals to other neurons using electro-chemical messengers called neuro-transmitters that attach to receiving sites located on the neurons themselves. There is a space between the end of the neuron and the receptor called the synaptic gap. As neuro-transmitter chemicals move across this gap, a small electrical charge is created. 
After one month of using Equisync, I feel relaxed, calm and not stressed at all, despite that I am leaving my present job soon for an early retirement, I handle the situation very well. I have the feeling that I’m going to be ok and there is nothing to worry about. This is what I have gained so far from using Equisync and it’s really meaningful in the erratic world that we live in.
A study that tested photic stimulation for reduction of poor behavior in ADHD children found that 15 sessions of photic stimulation between 12 Hz and 14 Hz resulted in behavioral change. This behavioral change was measured using the Achenbach Child Behavior Checklist – which accounted for not only the parent’s perspective, but self-reports from the children. Statistically it was stated that behavior improved up to 70% in the stimulation group compared to controls.

I’m kind of new to brainwave entrainment. So even though I might have been skeptic at first, my very first experience was rather surprising. I know, I’m probably among millions of people expressing the effects and benefits of brainwave enhancing auditory stimuli. But truth be told, if you have the right tone, the perfect serene place, and an unshakable determination? Then you’re on the right track. So I’d say? Give brainwave entrainment a try. You’re bound to feel the great benefits of these powerful, yet simple methods of mental boosters. Oh! Before I forget. Thank you for the interesting script mademoiselle. 🙂
I have discussed these findings with my sister, and two nice which are professionals in the fields of psychology, and medicine respectively (my sister and older nice have vast experience on the psychology arena, and my younger nice is a pediatrician), and they all agree this therapy can be of a great benefit applied in conjunction with traditional self-improvement programs.
“A light sound machine is a brainwave entrainment tool.  Using sound (headphones) & light (strobe light goggles) stimulation, listeners are gently guided into specific brainwave states. Each audio beat and pulse is a specific frequency. Our minds ‘think’ in terms of frequency. Brainwaves change frequencies based on neural activity within the brain. Hearing and vision are considered the favorable senses for affecting brainwaves safely. By presenting beats and pulses to the brain, the brain begins to mimic or follow the same frequencies. This process is referred to as entrainment. In essence, these instruments speak to the mind in it’s own language – the language of frequency.”

In all professionally produced meditation programs, you train your brain gradually. That is how you successfully develop. Just like training the body, you progress gradually. This is the key. In BrainAscend you start with level 1. Each track is 30 minutes.  Use it once per day for 30 or 60 minutes at a time (once or twice in a row. Use repeat/loop function in your player) or twice per day for 30 minutes at a time. You should use every level for at least 2-3 months before moving to the next. The exception is level 1 which is an introductory level which you can use for a week or so. After that time, if you can repeatedly remain fully aware on your current level without falling asleep (even if playing it twice in a row) you can move on to the next level. Until then you should continue on your current level. Listen with closed eyes, either sitting up or laying down.


Hello Chip, I did a little research for you and it looks hopeful. “Even when a person is deaf binaural beats can work. By putting the headphones with the binaural recordings behind the ear, the sound waves travel to the brain through the scull and entrain the brain just the same.” I can not corroborate 100% that this id a fact, however, if you are willing to give it a go I would love to hear how this technique works for you. Please keep my updated as to your progress and results. ~ Maya
I am fortunate to be working with Deepak Chopra, M.D., and Dr. Rudy Tanzi, co-authors of the bestselling book Super Brain, on a technology called Brain Wave Entrainment. Deepak is very well known, but Rudy is an amazingly interesting person as well. He is the Kennedy Professor of Neurology at Harvard Medical School and Vice-Chair of Neurology at Mass General Hospital. Rudy co-discovered three of the four original Alzheimer's genes and today runs the Alzheimer's Genome Project. He also plays the keyboards, including, at times, for Aerosmith. He is kind of a real life "Buckaroo Banzai."
Gamma brainwaves occur during creative thinking and processing of memory and language and in many learning activities. These brainwaves are not present at all when a person is under anesthesia, but return as soon as the person becomes conscious again. Multiple scientific studies have shown gamma brainwave entrainment to be helpful for reducing distractibility, improving short-term memory, improving motor coordination, and relieving migraine headaches.
Then in my own research regarding my life-long hypertension and its resistance to medication, I became very concerned when I learned that 145/95 is the gateway to dementia. At that time my BP was consistently 145/95. Then, even worse, it started to become routinely 161/106. I was simply unwilling to take more medication with all its attendant side effects, so I started researching natural solutions. I became aware of a breathing apparatus which sold for $300 that would help me train myself to deep breathe, thereby reducing my blood pressure. $300 seemed like a lot, but not in the scheme of saving my life. I started thinking. I already knew how to breathe from my brief studies in Chi Gung. I simply needed something to help me focus my mind. I tried using the Chi Gung breathing while simply counting 200 breaths. It worked for a short while, but I quickly became far too bored, even though I knew it could be a lifesaving measure. I had been considering EquiSync for sometime, and realized it was much less expensive than a $300 breathing regulator, and that it might serve a dual purpose. So I purchased the entire suite.
* We made the decision in this update to return Brain Wave to a Portrait-Only App. We know some people will miss the Landscape UI, but we did this to focus on the Brainwave Entrainment and Audio experience, and to prepare for new devices and screen sizes. Maintaining and testing portrait and landscape layouts for iOS 5-8, HD&SD, and 3 Aspect Ratios had become the single most time consuming part of our development and testing, and soon there will be even more. 90% of our dev and testing time was spent tilting iPads and iPhones of different sizes and different iOS versions, tweaking code that had nothing to do with brainwave entrainment--the reason I and others use this app everyday. Once the new Aspect Ratio devices come out and we have time to test with them, then maybe Landscape will make a comeback on the iPad.
Audio-Visual Entrainment (AVE) is a technique that utilizes pulses of light and sound at specific frequencies to gently and safely guide the brain into various brain wave patterns. By altering your brain wave frequencies, you have the ability to boost your mood, improve sleep patterns, sharpen your mind and increase your level of relaxation, all with the simple push of a button!
While originally brainwave entrainment was achieved by using pure tones of sound, it is now possible to take these tones and blend them with music, rhythms, and natural sounds, such as the sounds of flowing water, bird sounds, or waves lapping on a beach, creating extended tracts of varied and intriguing brainwave entrainment music for everyday use.
Specific tones that resonate at certain frequencies are created and embedded within the acoustic architecture of the original waveform. Your brainwaves latch onto these embedded carrier frequencies and attune themselves to the same vibratory rate. Brainwave entrainment now occurs that is similar to binaural beats yet there is no need for headphones to deliver these entrainment effects.
If you’ve used brainwave entrainment and experienced any benefits, feel free to share your experience in the comments section below. Be sure to discuss why you believe the entrainment was effective and/or whether you think it could’ve been a placebo effect. I’ve played around with the products and feel as if they are great for relaxation enhancement, inducing a temporary perceptual change (i.e. altered state of consciousness), and arousal reduction.
I’m sorry to hear you’re having these troubles. First off, I disagree with whoever told you it was a good idea to listen to 6 subliminals a day. I suppose I would need more context to better understand. Are these binaural beats or brainwave entrainment audios? If so you are definitely listening too much, and can harm yourself (just as the article mentions above from over-doing it). Even if they are not brainwave entrainment audios, I cannot imagine it is effective or the best idea to listen to so much so often. I would pick one subject that correlates to the most important goal for you and stick with it until you have achieved it. Remember to steer clear of that tempting idea of getting “all that you want for nothing”. Even subliminals are a tool. You still have to use the tool to do the work.
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?!
With digital upgrades, Berger’s machine is still in use today, known as an electroencephalography machine, or EEG. Berger used his machine to study the brains of psychologically normal and abnormal people and discovered the first brainwave, called the alpha wave and also known as the Berger wave, along with the faster beta wave, which he observed suppressing the alpha wave when subjects opened their closed eyes. 
Much of what is currently written about brainwave entrainment, especially on the internet, is simply … incorrect.  It seems par for the course that when something of huge value is discovered as a potential ‘internet product’ that it is going to be marketed within an inch of it’s life. And often with less than stellar regard for actual science, research, or factual knowledge. 
Most wisdom traditions have employed methods that allow the subjects' brain waves to slow down such as meditation, [Hindu] kirtan, [Gregorian, Menzuma or Sufi] chanting, Hebrew davening, Native American drum circles and rain chants, Tibetan prayer bowls, and whirling dervishes and African trance dancing. The rhythm of these wisdom tradition technologies actually slows people's brain waves from their normal busy brain frequency we call Beta (13-30 cycles per second or Hz), to Alpha (8-13Hz) -- meditation, Theta (4-8Hz) -- deep relaxation and dreaming, and Delta (.5-4Hz) -- slow wave or dreamless sleep.
A very pleasurable experience during listening (and often for some time afterwards). As Holosync® changes your brain wave patterns to those of deep meditation, the brain produces several very pleasurable neurochemicals, including endorphins (the same endorphins responsible for “runner’s high”)…as well as several hormones with a profound and positive effect on longevity, aging, stress, and well-being.
All brainwave states serve important mental functions, and with today’s lifestyle, returning to a peaceful way of being is becoming increasingly difficult to achieve and maintain for any period of time. This continual stress or alerted state causes disease in the mind and body, which is why it’s paramount for us to relearn or retrain ourselves to get back to these healthful and rejuvenating states.
Creativity: Measuring “creativity” is likely subjective, but many people stuck in a certain dominant brain wave may benefit creatively from shifting the brain wave dominance. Someone who has excess beta waves may fail to relax enough to access certain (potential) creative properties associated with increased alpha waves. Similarly someone stuck in a slow wave state may benefit creatively from increasing beta waves.
The reported PMS symptoms that improved included: affective lability, anxiety, appetite changes, bloating, breast tenderness, concentration difficulties, depression, fatigue, and irritability. Researchers noted that there was a clear “trend” toward a reduction in social withdrawal as a result of symptoms as well. A total of 49/50 women reported improvements.
In 1839 Heinrich Wilhelm Dove discovered binaural beats, which led to the further discovery of the frequency following response and the beginnings of the science of brainwave entrainment. This science uses the power of specialized sound to FORCE your brain to stop producing defective brainwave patterns - OVERRIDING them to create positive neural feedback instead. Endorphins are created to alleviate pain, serotonin increases to combat anxiety - happy brain chemicals of all kinds are made in response. And the best news? As you continue with it, your brain re-learns to produce these healthy, beneficial and healing brainwaves on its own!
Good article. Richard, there are numerous studies dictating the research behind entrainment. Please see http://brainwavebooster.com/brainwave-entrainment-research/ for a list of many peer reviewed studies. The author here is totally correct in his labeling of brainwave entrainment as a therapy tool. Hope this helps. There are other studies out there as well, one only needs to Google it.
Gamma brainwave states are the most rapid in frequency. Gamma has long been considered the brainwave that is able to link and process information from all parts of the brain. It is the frequency that brings with it the ability to process large amounts of information in relatively small amounts of time. Think of generating more Gamma activity as getting a processor upgrade for your brain.
Mood: While brainwave entrainment may not be a great option for depression, particularly in the slower frequency ranges, beta entrainment may improve certain measures of mood. Additionally it is important to consider the fact that many people experience detrimental changes in mood as a result of heightened stress and anxiety. Since brainwave entrainment has been shown to improve stress and relaxation, overstressed individuals may experience a simultaneous mood improvement.
So on thursday 21st July 2018 I tried marisa peers audio. She has a program that I bought that was just hypnosis audios. I then got three bonus audios. One of them was called money-wiring hypnosis typnaral alpha brainwave audios, which I tired for the first time. As soon as I went into hypnosis I had a weird sensation and my whole head and body stared stimulating to a point where I felt like I couldn’t really move. I thought maybe it was just me being more relaxed. Until I started to feel pain on the side of my head near my ear. I woke up after and went to bed thinking it will get better the next day. But woke up with a headache feeling sick and tingling and numbness near my head and jaw. I contacted them and they said it’s just blood going to your brain but now I feel tingling around my body and pain in my head and ears. I don’t really know what to do but team responsible for this hasn’t heaven me good answer since it hasn’t really gotten better. I feel on edge and losing energy. Please can some one advise.

Because the mind and body are a single system, changing our brainwaves and spending more time in harmonious, relaxed, and restorative mind-states also affects our physical health. Physical health then reinforces our mental-state, and a feedback loop of either positive or negative processes becomes established. Research studies have shown beneficial effects of using brainwave entrainment for treating migraine headaches, premenstrual syndrome, and for managing physical pain.

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.
Hi Amandeep. I am so sorry to hear you are having these troubles. I am not familiar with Marisa Peers materials, so I cannot comment on this, but I can tell you we have never had an experience like this reported from using the audios we offer on this site. I would cease any and all hypnosis or brainwave entrainment audios, and contact your doctor. The issues you are mentioning sound like they could be a physical issue that may be related to more than the audios you’ve listened to.
However, those with ASD are sometimes also diagnosed with ADHD. Although they are different conditions, some of the symptoms can be intertwined, which it appears may be the case with your grandson. So I would start by trying out my tracks for ADHD. You can try those out for free on my YouTube channel and I’ve put them together in a playlist here: https://www.youtube.com/watch?v=RKao2oZZPnw&list=PLveg0IEcZWN5iVmMduR9UjLzX_YgCetds. The corresponding MP3 versions for those tracks can be found on my site here: https://www.mindamend.com/intelligence-and-brain-power/. I hope that helps.

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.
Normally, binaural beats, isochronic tones, or monaural tones have a certain level of capacity to entrain neural activity—and then they bottom out. By combining really great entrainment tools, I wanted to create a better entrainment stimulus that could entrain more neural activity quicker, allowing us to go deeper much more quickly than we have ever been able to go before, and moving our meditation practice or spiritual development to the next level.

Hi. This article contains a lot of information about brainwave entertainment. Thanks. I have a question. I downloaded an Android app that plays isochronic tones. I like to use an Isochronic tone at 2.5Hz that is in Delta range and is supposed to help me get a deep and dreamless sleep. I use it without headphones and just keep the smartphone next to my pillow. But I do not know if I should keep the tone playing all the time while I sleep or put it on timer to shut off after some specified time. A custom timer is possible with the app. Can you please guide me.
