The formal name for this process is called the “frequency following response”, where the human brain will literally “follow” a specific frequency/beat after being exposed to it for (usually) about 8 minutes.  Technically the definitive term “entrainment” does not exactly match the actual process of what is happening to your brain when listening to these audios, but its close enough, and the name has stuck now with these products becoming more popular and widely known.
To summarize all this, we can see that the type of product you choose plays an important role in answering that question – “Can brainwave entrainment damage my brain?” My personal advice as a long-term user of the technology is to Be selective about what brainwave entrainment audios you download from the internet, and make sure to follow the instructions! 
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.
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.
Deep relaxation is another major benefit resulting from the brains cortical frequency following response while using brainwave entrainment. As the brain tends to mimic the rate of frequency it is exposed to, thus allowing it to enter into that brainwave state, this helps explain why this technology can produce benefits commonly found with meditation.
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. 
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.

“A quite different phenomenon results when stereophonic earphones are used and the signals are applied separately to each ear. Under the right circumstances beats can be perceived, but they are of an entirely different character. They are called binaural beats. . . . Binaural beats require the combined action of both ears. They exist as a consequence of the interaction of perceptions within the brain.”
From the deepest, sincere, compassionate, and loving part of my soul; I offer thank you. : ) By saving me, I believe your organization did a service to society as a whole, for now I am like a ripple in a pond that will reverberate good vibes to all who I come into contact with. I express compassion, understanding, and knowledge to all who I see need your life saving, and healing product. Like a missionary I desire to spread it; for it is pure, good and loving to my fellow man.
Rather than discontinuing my meditation practice altogether, I instead began researching methods of increasing the effectiveness of meditative practice. This seemed an inevitable decision for me in light of the undeniable improvements I had witnessed in response to previous experience with meditation. This resulted in my eventual re-discovery of brainwave meditation programs brainwave synchronization. I had used a few different such products previously, but none that seemed effectively designed to meet my specific needs. After deciding to try a particular brainwave meditation program, I found it to greatly assist me in producing all of the previously experienced benefits of meditation, but in a shorter period of time and in a much more focused manner.

Brainwave entrainment is clearly NOT an effective standalone treatment for mental illness, but it may be an effective adjunct treatment in certain individuals. It should also be mentioned that when using brainwave entrainment, you may want to have a specific purpose in mind. If your goal is to relax, yet you’re using a protocol that is stimulating, you may falsely conclude that it doesn’t work even though you’re using the wrong protocol.


So my question is: Why? When I read it, I had a bit of a fear of brain aneurysms. Therefore, 1. could someone contact me to tell me why use of your product shouldn’t continue past 2 hours? [I probably won’t heed the reason unless it’s a life or death warning: I love this product that much!] 2. Please feel free to post my letter in your testimonials, if you ever decide to post such customer comments.
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.
Brainwave entrainment also happens with the use of pulsating light, and visual and auditory stimuli are sometimes combined for additional effect and visual stimuli is used alone. Using brainwave entrainment techniques is safe for almost everyone, the exception being pregnant women and people who have seizure disorders who should check with their physician before using these methods.
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...]
My personal experience of this was that it could get very harrowing; at times, I would literally be gritting my teeth and contracting my ribs while I was in meditation, because it was pushing me so hard. I began to ask, “Is it necessary to push this hard in such a static way and create overwhelm over such prolonged periods in order to propel spiritual evolution?”
Brainwave Entrainment is the process of synchronizing the brain to specific frequencies and patterns embedded in audio tracks. These frequencies correlate to specific emotions, feelings, and even energy levels. Using nothing more than sound, Brainwave Entrainment can enhance creativity, change moods, and even alter behavior like sleep and energy levels.

Altered states of consciousness: In as early as 1987 it was discovered that photic stimulation at specific frequencies produced an altered state of consciousness. An extremely small study with just 4 individuals involved photic stimulation at 6 Hz, 10 Hz, and 18 Hz. The results were reported to have altered their conscious awareness. This really isn’t that surprising to anyone that’s used brainwave entrainment therapy.

There basically are a few things that you can use to deduce whether you think these claims are true, and will work for you.  A few manufacturers of this type of product have taken the time to hook up experienced meditators (like zen monks) to encephelographs, then fashion their audios to mimic what is occurring in these deep meditators’ brains.  It would make sense then, to a large degree, that you could experience similar benefits from your brain undergoing this process.

This is a question I have noticed to concern many people, who are researching the issue. I have come across this question in forums, Yahoo Answers, in blogs, and all other sorts of  places. I can definitely empathize with someone who is looking to find a solution to a problem like anxiety, migraine, pain, etc., and needs reassurance and scientific proof that brainwave entrainment actually works!
The Brain Wave app uses advanced sequences of binaural tones that are combined with configurable ambient nature sounds and atmospheric music (or a person’s iTunes Music) to stimulate specific brainwave patterns.  It includes powerful binaural sequences for sleep, focus, energy, positive mood, confidence, anxiety, stress relief, relaxation, yoga, memory, motivation, headache, concentration and meditation and more.
I love your tapes! I bought them a few weeks ago and have greatly benefited. I’m also a holistic practitioner and have recommended them to a number of patients. And today when I made my last referral to your website for them to purchase from, it occurred to me that perhaps you have referral discounts, or wholesale prices for practitioners, and that I should ask?

Theta waves have another interesting characteristic. The Earth has a measurable resonance of 7.83 hertz known as the Schumann resonance. Because the Schumann resonance is a constant background frequency surrounding all life, it may play a special role in biological activity. The Schumann resonance frequency falls within the range of theta brainwaves and may have something to do with why these brainwave frequencies are so powerful. 
Behavior problems: In two separate studies with a total of 57 children, it was found that brainwave entrainment was able to significantly improve behavior problems. One of these studies was conducted on children with ADHD and determined that they significantly improved not only in regards to attention deficits, but also in their behavior. Both parents and teachers reported statistically significant improvements in how the children behaved.
I have also noticed that during my morning meditation session (I use the product twice daily – once in the morning and again at night), I’m able to almost instantly reach extremely deep levels of relaxation. In fact, within minutes I lose all sensation in my extremities. This is exactly like yogic meditation’s pratyahara, or sense withdrawal, state. It’s really quite remarkable that I could get that relaxed that quickly. This process usually takes me anywhere between a half an hour and an hour and a half. With EquiSync, I reach the same state in literally 2 to 5 minutes!

Hi please can u help me I have anxiety mainly due to sleep issues and I tried hypnotherapy two years ago and I had a very bad effect I have tried to reverse it but it’s not too good I always have to get into this trance at nite and then try to sledp I wake up in the morning with my head pulling every day if I listen to delta wave music will it help me get out this state and dies delta wave music gradually take u down to sleep please help urgent
“A quite different phenomenon results when stereophonic earphones are used and the signals are applied separately to each ear.

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.
Brainwave entrainment can help you with this in a few different ways. First it has a tendency to help you relax very deeply. Just the act of relaxing daily will help to alleviate this stress and allow the body and brain to recoup. It also will stimulate the brain and body to produce more serotonin, dopamine, and melatonin, which will also help to improve your mood and keep you relaxed. But the greater benefit that comes from regular use of this technology is in its ability to enhance your awareness and perception. It can stimulate your brain and mind to have greater insights, greater flexibility and creativity in the decisions you make as you move through life, and this gives you a more resourceful means of finding your peace and resolving the problems and challenges you face in your life.

This is good to understand because this is another area where people can make huge promises that may or may not be true. Even in this realm, there is a level of practicality that can be followed. Even meditating at the rate of a super-human monk is not going to “magically solve all your problems”. This technology cannot pick negative beliefs out of your head and implant positive ones just by influencing your brainwaves. It cannot just make you a different person.


Chronic fatigue: Subjective improvements in energy level may be reported by those who increase stimulatory beta and gamma waves. Fast waves tend to be associated with higher levels of arousal. Low arousal is associated with chronic fatigue and may be exacerbated by slow brain waves (e.g. theta and delta). As of now there aren’t any studies that have analyzed various protocols for their effect on a person’s energy or arousal.


3) God Consciousness from Ennora. Wow - quite a name, no? Hmm - well I don't know if I felt God, but I certainly felt something ... and at the time of writing, they have got a massive sale on, with downloads costing $11 (rather than $25), so you'd be mad not to leap at this if you're the spiritual type. This isn't the only reason to choose Ennora, however - this recording has got brilliant, soothing rain sounds, it works, and it certainly gave me the advertised "everything will seem perfect". 30 minutes long again. Good stuff, perhaps not one for the atheists though :)
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.

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.

Alpha stimulation: Stimulation of alpha waves has been shown to provide stress-relief among employees, is able to provide pain relief, and improve measures of competence and recognition. If you have significant work-related stress, entraining certain alpha frequencies may help you decrease arousal and improve relaxation. Post-surgical stress doesn’t appear to benefit from alpha stimulation.

Also, don’t you think that the inherent hemispheric synchronization using binaural beats might be a positive benefit within itself? While it’s true that the huge majority of us use both sides of our brains most of the time, it’s also true that many of us are a bit polarized to one side or the other in general, or when doing a particular kind of activity or focus. I’ve found stimulating a more equally and consistently whole brain activity has it’s own benefits other than the entrainment aspect.
