The main gist of brainwave entrainment audios, without getting too technical here, is that they effortlessly guide one’s brain (when listened to with stereo headphones) into a specifically targeted state, as designated by the creator of the audio. They are able to alter your brainwave states through the use of specific audio frequencies, and specific beats-the most common of which being binaural beats (though there are other types of beats being used as well).  When one frequency is played into one ear- let’s say 1115 Hz- and a slightly different frequency is played into the other-say 1125 Hz- the brain is forced to reconcile the two, and creates its own “phantom” frequency that is the difference between the two- in this case 10 Hz.  Not only does this allow the brain to be led into specific brainwave states, but it also allows the two hemispheres of the brain to synchronize with each other, stimulating and promoting whole-brain functioning.

Brain Wave Entrainment is any procedure that causes one's brainwave frequencies to synchronize with a periodic stimulus (sound, vibration or light) having a frequency corresponding to the intended brain-state (for example, to induce a trance, dreams, sleep or relaxation.) It is also called the Flicker-response because of how staring at a campfire or the flickering of a burning candle can lull you into a state of calmness and serenity. There was an extensive article on this phenomenon by Gerard Oster in Scientific American in 1973. It may sound novel, but in many ways, this is old tech.


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.
In fact, there is more to answering this question than meets the eye. As someone who’s also been skeptical enough to do the research, I am more than happy to explore the issue in great depth. The important thing to address here is what have you been told that Brainwave Entrainment would do?  Depending on whose site you’ve landed on you may have been promised different things.  The promised benefits of this type of product are a long list, and more things are still being added to it.  You may have been told that brainwave entrainment would help you meditate deeper, and rocket launch your spiritual evolution from doing so.  You may have been told that it would help your brain release positive neuro chemicals and anti-aging hormones that would improve your health and help you feel more positive emotions, overcoming anxiety, and you also may have been told that listening to brainwave entrainment on a regular basis would help your brain evolve, building a higher threshold to mental and emotional input, growing neural pathways, and synchronising the two hemispheres of the brain.
One RCT (n=108) showed significant reduction in anxiety from a single session of alpha/delta therapy for day surgery patients. A crossover RCT of a single session of theta stimulation in four healthy adults reported significant improvement from the intervention in one of five measures. Five pre/post studies reported significant benefit from the intervention for 16 of 27 outcomes.
I was using Jeffrey Thompson brainwave cd material for several weeks and suddenly developed severe anxiety, headaches in the forehead and dizziness and confusion . I stopped but the symptoms are still with me a week later. Will these symptoms go away? This isn’t some bad kundalini awakens g it something is it ? Will I get better snd how long will it take to go away? Message me at eurydice@cruzio.com or message me in FB at Nicholas Pierotti (the guy in the hat hugging his daughter ) Please let me know
My final point is that brainwave entrainment is worth trying, and instead of being stopped by the fear of its improper use, you better reap its numerous benefits by following the safety guidelines I went through in this article. So, it all comes down to the question – are you ready to take your ability to create what you want for yourself in life to the next level?
Generally, the established brain entrainment technology has been to use various static levels, lowering the carrier frequency of the binaural signals over time. By doing this, you basically increase the resonant power of the carrier frequency to resonate more deeply with the resonant frequency of the brain and the nervous system. This process pushes the nervous system over time. The limitation I find with this system is that it takes a static approach, in the sense that it gives the nervous system the same degree of stimulation day in and day out. The idea here is that if you keep whamming your nervous system with the same stimulation on a daily basis, it will eventually kick in and learn. Then your nervous system and your brain will jump to the next level.

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.
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.
Slower still are theta waves. Theta is best known as the brain wave state of dreaming sleep, but it is also associated with a number of other beneficial states, including increased creativity, some kinds of superlearning, increased memory abilities, visionary experiences, and what are called integrative experiences (where we make broadly-based positive changes in the way we see ourselves, others, or certain life situations).
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.
If you're struggling to focus and feeling a bit tired and unmotivated while studying, you can help boost your concentration and energy levels by increasing Beta activity.  The SMR range is right at the bottom of the Beta range, so it's not too intense, and so is ideal for playing in the background and using as a general study aid.  If you are looking for something a bit higher for a more intense focus session, try my Study Focus isochronic tones session, which uses frequencies between 14-17Hz.
“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.”
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.
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.
Kelly Howell brings 30 year's experience to her expertise. She has been cited by the Mayo Clinic as "renown for her pioneering work in healing and mind expansion (and) visionary recording techniques." She has collaborated with neuroscientists and biofeedback therapists to invent a sophisticated sound recording technique that makes Brain Sync programs more effective. The result is the most elegant and effective brainwave synchronization audio programs available in the world today. You'll feel the effects from the very first time you listen. With regular use, you'll establish new healthy patterns that last. Brain Sync programs use window frequencies – extremely precise frequencies that fit through narrow biological windows to impact the body at the cellular level. The choice of frequencies selected for each program is based on biofeedback research. Programs are designed to help you self-generate optimized brain states exhibited by remarkable men and women.
Isochronic tones are the most recent and advanced method for brainwave entrainment audios. With isochronic tones, the same intensity is used for all tones, but they pulsate on and off at different rates. The speed, pattern, and rates of these tones can be changed and altered throughout the recording, and the brain will follow them into desired states. The use of isochronic tones opens up the ability to lead the brain into highly specific states, at specific speeds and intensities. This has opened up the doorway to producing both dominant and subdominant waves(i.e. an alpha brainwave state with subdominant theta waves), and the ability to lead the brain through different waves, at specific speeds (i.e. holding the brain in an alpha state for 10 minutes, then dropping it through theta for 20, and holding it in delta for five before bringing it back into alpha at the end of the recording.) This allows thousands of different possibilities in training the brain, and also makes the process of listening to these types of audios more natural, and more powerful. 
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..
Targeted hemispheric changes: Some speculate that specific alterations in brain waves can be made on an individual basis. In other words, you can target one frequency in one hemisphere (via the right ear) and another distinct frequency in the other hemisphere (via the left ear). The left ear affects the right hemisphere and right ear affects the left hemisphere.
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.

The implications and potential benefits of brainwave entrainment technology are staggering, and a seemingly infinite amount of doors have been opened to be explored.  This technology is highly useful in the self-help/personal development field in a variety of ways.  It can also be used to enhance NLP and hypnosis recordings to make the mind more receptive to suggestion.  Brainwave entrainment can be applied to help people fall asleep, to improve focus and concentration, or to relax.  Recent and modern experiments are also being held to see if brainwave entrainment may help  to treat and/or cure mental “disorders” such as depression or ADD.  One of the most common and popular uses of brainwave entrainment is to effortlessly induce deep meditative states.

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.
I tried other companies the last few years or so….among the likes that mainly used binaural audio and the deepest I was really ever to achieve was alpha state….maybe theta once or twice over the last few years. It takes incredible dedication and practice to achieve the deep, renewing states of meditation that are most sought after…..I listened to the theta meditation mp3 last night and within what seemed like a few minutes my mind was flooded with imagery…memories long gone…my body was sleeping, heavy as lead, but my mind was crystal clear, aware of my surroundings. I could barely even open my eyes!
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.
Deep relaxation is a major benefit resulting from the brain’s cortical frequency following response. By selecting the desired rate the brain, via the frequency following response, will tend to mimic the rate it is exposed to and thus enter that brainwave state. This helps to explain why this technology can produce benefits commonly found with meditation. One of the most valuable benefits of consistent  brainwave entrainment is that we are able to experience and recognize the various states of consciousness. With practice we can learn how to re-create these states.
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.
Theta brainwaves in the frequency range of 6 to 9 hertz are known as thalpha waves because of their proximity to alpha waves. They are seen during states of high suggestibility, during hypnosis, and during paranormal experience and are also connected to an increase in human growth hormone (HGH) levels and higher blood flow to the brain. Theta brainwaves sit between the realms of the subconscious and conscious mind, making them an especially useful brainwave state for developing creative thinking, working through emotional problems, and integrating subconscious and conscious experience. 
So often it is presented as such a highly scientific technology that can only be created by “experts”. Buzz words like “scientific”, “certified engineer”, “frequencies”, “cortical evoked response”, “anterior brain activity”, are used to make it seem over-complicated, and pseudo-scientific pictures of “data” and “brain readings” are pasted all over sites to further qualify claims of how powerful and amazing these people’s product is.

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.
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.
There appeared to be some evidence that 10 Hz stimulation (alpha waves) improved anxiety, but it wasn’t statistically significant. A study that utilized a ramping format of alpha to theta to delta waves (over the course of 10 minutes) found a significant improvement in anxiety. In terms of long-term stress, there is evidence that alpha and beta stimulation improved measures of “competence” and “emotional exhaustion.”
By exposing an individual to repeatedly external stimulus which can be flashing lights and/or recurring sounds, the entrainment process consists in pushing the brain to adjust to match the frequency provided. Unlike other forms of neurotherapy which require the individual to actively respond to stimulus, entrainment creates an immediate neurophysical response which is instinctive and effortless for the person being provided with the light and/or sound combinations. The key outcome of the sensory stimulation is known as the ‘Frequency Following Response’.

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.
In 1973, biophysicist Dr. Gerald Oster published a famous article in Scientific American titled “Auditory Beats in the Brain”, which found that when two pure tones of varying frequencies were combined, a third rhythmic beat was created which he called binaural or monaural beats. According to Oster, monaural beats occur when two tones are combined and sent through a loudspeaker, while binaural beats occur when stereo headphones are used to deliver each tone separately to each ear. Oster concluded that monaural beats were a more effective form of brainwave entrainment.
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. 
Audio-visual entrainment (AVE) is an effective tool for dissociating the depressed/anxious person out of his/her destructive thoughts. Even with increasing anxiety, AVE has been shown to reduce heart rate … reduce jaw tension from stress … increase blood flow in the eyes … and increase peak-alpha frequency … Many homes have two to three [AVE] systems in them for family members to use following a stressful, tiring day in the modern world.
PMS: There is a little research that supports the efficacy of brainwave entrainment for PMS symptom reduction in women. Women with long-standing and severe forms of PMS were administered photic stimulations for a series of 3 menstrual cycles. Following the photic stimulation, it was noted that women reported 64% improvement by the second menstrual cycle and 76% improvement after all three cycles.

Participating in this program requires that you use your Holosync® soundtracks (!)—which takes some time. Though you’re free to do less (and progress more slowly), we suggest that you start with a half hour of listening each day, progressing to an hour a day. My bet is you’ll eagerly look forward to these sessions, though, rather than seeing them as a chore.

Regular production of Alpha brainwaves ensure that your immune system stays in top shape. This is made possible since they’re able to keep the body relaxed, thus reducing the chances for stress to build up. As a result, your body doesn’t end up producing harmful chemicals which can harm your immune system. By keeping anxiety and stress at bay, Alpha brainwaves reduce your chances of having to deal with stress-induced or anxiety-related sickness.

Hi Julie! You’re very welcome for the info. In answer to your question, I think some are probably good, and some not so good. There are many people putting brainwave entrainment out there these days and it is not so easy to figure out which ones are and aren’t of reliable quality without investing time and doing some research. I would say (in general) that paid products are probably better quality than free ones, but I couldn’t guarantee this is a golden rule. My best advice is to just do your research before spending too much time listening to the freebies.
I was not looking forward to returning back to my house as I live on my own so was very pleased to see that the “equisync” CDs had arrived in my absence. Ever since I have been back I put a CD on each evening and the change has been totally fantastic. The meditation is unbelievably calming and soothing, the inner-voice has been silenced and quite often I just put it on to drop off to sleep with the sound of gently falling rain. I can feel each day starting calmly and things like organising the memorial service have not been the strain and upset I would normally have expected. I could wax lyrical for hours because the benefits are truly and utterly fantastic. Never did I think I would find anything that would lift my spirits, clear my mind, calm the inner space but Equi-Sync has done that, and more.
Hi Marko, that isn’t one of my videos you referred to, so I can’t really answer you properly as I don’t know how their track was created. For the best answer, you should really contact the video creator. There isn’t any research that I’ve seen to suggest that you could harm your health by looping a delta track. During a typical sleep cycle, your brainwave activity will usually go up and down between the delta and theta range. It may be that you won’t experience the same quality of sleep if you spend most of your time producing mainly delta activity. With my 8-hour sleep track, I fluctuate the frequency range to try and emulate a typical sleep cycle http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/.
