First discovered by biophysicist Gerald Oster at Mount Sinai Hospital in New York City, Brainwave Therapy sends pure, precisely tuned sound waves of different frequencies to your brain via stereo headphones. In his EEG research, Oster discovered that when different vibrations, or sound frequencies, are delivered to the brain separately through each ear (as with stereo headphones), the two hemispheres of the brain function together to "hear" not the external sound signals, but a third phantom signal. This signal is called a binaural beat, and it pulses at the exact mathematical difference between the two actual tones. For example, a signal of 100 Hz delivered to the left ear, and a signal of 107 Hz delivered to the right creates a binaural beat of 7 Hz that in this case falls into the Alpha range
my daughter had an EEG and the neurologist said the brain wave activity in the back of her brain was very slow. I want to find out what causes this. She had a brain injury (3 skull fractures that were in the right side of her head and across the front right side. The fractures were closed wound. She had a small amount of swelling which diminished on it’s own. The neurologist asked if the fractures were in the back of her head and I told her no. She had no explanation for me.
Thank you for the info. I must add that the Yoga Nidra state is the state in which a person can be in Delta but fully conscious. I did experience this state accidentally 3x in 2yrs after discovering Swami Rama’s teachings about the state&1 of the techniques for it(only 4 seems to exist & are practiced in monasteries at the time,according to him. He was the yogi who 1st demonstrated the 4 states,fully aware of himself & his surroundings, under lab conditions).

3) Theta waves – these waves exist between 4 and 7 Hz. This state is commonly referred to as the dream or “twilight” state. Theta is associated with learning, memory, REM sleep and dreaming. Memory development is also enhanced while in this state. When in a theta brainwave state, memory is improved (especially long-term memory), and access to unconscious material, insights and creative ideas is increased.
Hi Ulka, thanks for your compliment on my article. Unfortunately, I haven’t come across any studies or much discussion about the problem with habituation and isochronic tones and how to overcome it. The consensus among experienced users is to regularly change the frequencies and music soundtracks you listen to. Adding music to the tones does change the waveform you are stimulated with, so that’s one of the main reasons why I provide different soundtracks for my isochronic tones sessions. I have released some tracks which use amplitude modulations in the music, instead of isochronic tones. It might be worth giving them a try if you haven’t already. I have them in a playlist on YouTube https://www.youtube.com/watch?v=Lj5tHl2cuWw&list=PLveg0IEcZWN6OIRZyLkv0BJADY7Q6xFCl.
Unlike many traditional therapies for dealing with stress, anxiety, depression or cognitive impairment, entrainment does not require a focused effort from the person having the therapy, as the brain instinctively follows the frequency. This makes it a much more effective therapy for managing some of these challenging conditions, by automatically inducing a sense of relaxation and a reduction in negative physical and emotional patterns.

At the beginning of May, I decided to change over to EquiSync because it’s much cheaper and let me experience the deeper levels sooner. At best, my blood pressure has been down to 66 and after cups of tea and food, back up to 76-80 which is regarded as acceptable. I was able to achieve these wonderful results in less than 6 months of daily practice of meditation using audio-beat technology.
This thing blows my mind! The first time I used it I was like "No way!" As I kept using it I discovered that it is literally the only way I am able to fall asleep nights when my mind is so full of thoughts and my anxiety is running rampant! I hate the way sleep aids make me feel like I've been run over by a freight train. I recently switched from using "Deep Sleep" to "Dreamy Sleep" and had the craziest dreams! I normally can't remember my dreams and I was actually able to recall quite a bit of them. Unfortunately last night, I dreamt that I faked the death of my dog last year and I felt like it lasted the whole night so I think I'll be switching back to "Deep Sleep" :( Awesome product though. My *only* complaint is that I wish there were more ambiance options or the ability to use it with Pandora. You can use your own music but I don't have much personal music on my phone so I am limited to using the app's ambiance tracks and they get old after a while. Highly recommend!
I want you to know that I only post reviews and recommendations for products that have been personally tested by myself.  I have been in this game for more than seven years, and know that there are a lot of products out there in varying degrees of quality.  I have set up this page with the goal of saving you both time and money in exploring this realm, so you can get straight into the game of bringing yourself to that next level in your own personal development.
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. 
Sound and light are the most popular methods to entrain the mind, yet there are a few other options in our toolbox. Using vibrational energy from sources such as magnets and electricity has been proven to help overcome addictions, depression, and even treat neurological disorders such as Parkinson’s. In this section, we cover these alternative forms of brainwave entrainment.
Since the beginning of this year, I’ve been doing meditation with the help of audio-beat technology from a well-known brand, which I thought was a bit expensive. But, at least it gave me an insight into how the mind could and would give me an edge in solving most of my problems. From February, I decided to double the dosage to that which was recommended by the firm as I was desperate for a cure.

I have had your Equisync CD’s for a little more than 2 years. Some recent stresses prompted me to start listening to them again. Wow……these cd’s are no joke. I have been playing them consistently for the past 2 weeks and they are a tremendous help. I have to ask about the Equisync III cds. Can this elicit a detox reaction? I played it in its entirety one night and the next morning I felt like I was having a healing crisis. I am not complaining 🙂 I believe these particular cds allows tremendous amounts of healing light to enter the body through the higher chakras.
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?

All brainwave frequencies are useful and beneficial at certain times – there is no brainwave that is intrinsically better than another. However, by deliberately choosing to attain a particular brainwave state, a corresponding mental state can be brought about at the same time. For example, a working person who has been in an overly alert beta brainwave pattern for many hours can quickly shift their mind and body into a relaxed state by listening to a few minutes of brainwave entrainment music for inducing alpha or theta brainwaves.
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.
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.
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.

Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.
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.

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.
So discovering the field of Brainwave Entrainment is very exciting and promising. However intriguing, there are a few things that make me a bit sceptical towards it. F.i. I’m not too keen on having to rely on any external stimuli, as (regular) meditation is one of the very few things where you are absolutely independent from anything external to make a change within, which to me makes it so special.
Again, it is important to be cautious of claims for things like these, and to find a brainwave entrainment seller that you can trust to make quality audios. It is incredibly easy for someone to throw together an audio without much to it and make all kinds of claims about what it can do for you. Please feel free to read through our reviews on the site to see some of the products I have tested and found to be of a reputable quality.

Brain Sync audio programs deliver pure and precisely tuned sound frequencies to the brain to drive brain activity into high level states of mind. These are brain states known as Alpha for heightened creativity and deep relaxation; Beta for high focus and concentration; Theta for meditation, insight and memory; Delta for deep sleep and healing; and Gamma to increase cognition and improve IQ.
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. 
BrainAscend is a completely free meditation program featuring 5 deepening levels, meaning 5 free MP3 tracks using brainwave entrainment technology, created by Marcus Knudsen, inventor of BlissCoded sound. It uses the scientifically proven most effective brainwave entrainment technology in a special process that steadily expands your brain power and consciousness level.

Hello, I am [name removed], from [city, state removed]. I would like to say thank you for making the CDs. They’ve really helped my friend get over years of abuse and the sadness of loosing the only good friend he had after he moved to [city removed]. I plan on getting the cds for myself, once I get to working, and seeing if they will help me with my problems caused by [condition removed]. But, if you had seen my friend before, and compared it to now you would be amazed.

Placebos do not work on me. Heck, even some low-mid doses of proven, effective medicine do not work. Or work well. Ever since I fell terribly ill in grade school, my brain had fundamentally changed. Before, I could comprehend anything. Tell me, show me and I understood it – no matter how advanced it was. I was in the top 98th percentile in the nation. BUT, you never know what you have until it is gone!


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.

Initially the children were entrained to a mu-alpha rhythm (7 to 9 Hz) to decrease theta waves. After the initial mu-rhythm entrainment, they entrained SMR-beta waves for 22 minute sessions. The results as interpreted by TOVA demonstrated significant improvements in: inattentiveness, impulsivity, and variability. Teachers and parents also reported behavioral improvements among the children. Using the right brainwave entrainment protocol may be a potential Adderall alternative for those with attentional deficits.

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.

Delta brainwaves have the slowest frequencies, ranging between 0.1 and 4 hertz, and these are the brainwave states associated with deep sleep, trance states, and unconsciousness. Few people can remain awake during delta brainwaves states, although this state is recorded in awake infants between ages of three months and one year and also in babies just before birth. Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin.


Over the past few years, brainwave entrainment products have made a great rise in popularity, reaching more people than ever before and peaking their interest with the many benefits ensured. We now have a continually expanding pool of options to choose from, as well as more information and scientific research on the subject than in the past.  Brainwave Entrainment audios, and the products being made with this technology are literally changing the game in the personal development field, and have become one of the largest catalysts in our recent evolution as a human race.  In fact, these audios may be one of the main contributing factors in unlocking the potential to tap into the untouched 98% of our brains that we are currently not using.

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: 
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. 
Give thanks. I am currently on a journey of discovery in regard to brainwave entrainment. I have shared this information with individuals with ADD as well as other chronic and serious physical ailments. I plan to continue to share with those I know who are suffering depression. I am totally amazed, almost stunned at how well this works. I do believe in the creator. I am humbly giving thanks. Incrediable. Much love and light to all especiallly to Andy for sharing this elegant modality.
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.
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

There are many advantages and disadvantages with binaural beats. One of the major advantages is hemispheric synchronization. Since both hemispheres are required to create the beat within the brain, this method is an excellent way to create greater harmony between areas of the mind typically functioning independently. Binaural beats are also known to have effective hypnotic and relaxing effects.
Yes, brainwave entrainment is based upon science. It has been scientifically proven to work, and to benefit the brain in all kinds of amazing ways. Yes people use things like EEG machines to read how it works on the brain. BUT, this does not mean it is overly complicated, and it does not mean that you have to be overly techy or scientific, or have any experience in neurology at all to create a brainwave entrainment audio or understand how it works.
Besides, Holosync® users look forward to their listening session because the experience is wonderful, and you feel so good afterwards. But still, you do have to be willing to actually use the program. If you aren’t willing—if you don’t think the incredible mental, emotional, and spiritual benefits of this program are worth the time commitment—this isn’t for you.
Practitioners are discovering a number of different areas in which entrainment therapy may bring positive benefits. From managing mental health more effectively through to providing increased mental focus and concentration, it is thought the technique can be adapted according to the specific issues being treated. An improved immune system, enhanced levels of pain management, and a reduction in autoimmune disorders are also thought to be achieved through the therapy, leading many individuals with chronic ill health to consider brainwave entrainment as a non-invasive yet effective therapy.
Maybe a favorite popular song, a certain piece of Classical music, a raucous dance beat, the pulse of Reggae, Indian, or African drums, or the chanting of Gregorian or Tibetan monks, but you probably know how the sound of music, drumming, or chanting is capable of transporting you into an altered and joyous state of mind and uplifting your spirits.
PPPS. You won’t BELIEVE the amazing change that YOU are about to experience. I’ve seen thousands of individuals undergo powerful shifts in their consciousness as a result of using this program. It’s EMPOWERING, and it’s available right now after 10 years of intensive testing and refining. Discover the magic for yourself! Purchase the CD version, or the download version!
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.

This brainwave only appears whenever a person is awake and relaxed, a one-of-a-kind distinction among other types of brainwaves. 

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?
The eyes of the participants were closed and the VFP goggles illuminated in alternative manner; first the right eye, then the left. The rate at which the photic stimulation was conducted ranged between 0.5 Hz and 50 Hz. Of the 50 patients with migraines, 49 considered their headache as having been “helped” by the stimulation and 36 noted that their headache had completely “stopped” from the VFP goggles.
At any rate, I am enjoying the product immensely. I’m keeping a journal in which I’m recording my thoughts & observations as well as memory and cognition scores just as a sort of completely unscientific pet project, out of curiosity. So far, I’ve benefited from being better rested and more focused as a result of your product and that alone is worth the price of admission but I hope to be able to show that over an extended period of time, EquiSync can also improve working memory, cognition, &etc. I’ll be sure to share the data I collect with you if I get anything of statistical significance.
In the past few issues of the Advocate Voice Newsletter and the Fibromyalgia & Chronic Pain LIFE magazine, we have offered ideas about  several forms of cognitive behavior and mindfulness information.  In the chronic pain community these techniques combined with other therapies, including medications and alternative modalities, can help people sleep, function, relieve stress from pain and improve their quality of life.  This month’s app, Brain Wave, 30 Binaural Programs, is another tool to help introduce the idea of using your mind to help control pain and relieve stress.

In general, we are accustomed to being in the beta brain rhythm. We are in a Beta brainwave pattern when we are consciously alert. It is the default and dominant brainwave for most of us most of the time. We are in Beta when we feel agitated, tense, hurried, pressured, afraid and stressed. The frequencies range from 13 to 60 pulses per second in the Hertz scale.
I would like to share with you my experience after using EquiSync for three weeks. First of all, I am so amazed how fast I can put myself in a meditation state. During meditation, I feel some kind of a sensation I could not explain. I feel the rain dropping on my face and sometimes my legs. I feel the breeze of a tropical weather as if I was in the forest. I always sleep for a very short time at night and I have a very high sense of smell all my life. Using equisync I still sleep less, but am more relaxed when I wake up. During meditation, I can also smell the forest as if I am in the forest.

Today, EEG machines are used for diagnosing epilepsy and sleep disorders, for determining dosages for anesthesia, and measuring the brain activity of people in comas or suffering from brain trauma. EEG machines also continue to play a role in researching and understanding brainwave entrainment and developing new and better methods for delivering the benefits of this form of brainwave modification. 
If the further development of consciousness and awareness is your ultimate goal, there really is no substitute for actual meditation, of which many techniques are the result of thousands of years of human endeavor and accumulated knowledge and experience. Sure, it's not as easy as putting on headphones and pushing a button, but achieving authentic inner peace and relief from the stresses of human existence will mean so much more to you when earned through the time-tested route of traditional meditation. (Plus, once you learn to actually meditate, you can do it anywhere anytime without having to rely on being plugged in to something!)
“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.”

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.

If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
