Brainwaves, or neural oscillations, share the fundamental constituents with acoustic and optical waves, including frequency, amplitude and periodicity. Consequently, Huygens' discovery precipitated inquiry[citation needed] into whether or not the synchronous electrical activity of cortical neural ensembles might not only alter in response to external acoustic or optical stimuli but also entrain or synchronize their frequency to that of a specific stimulus.[16][17][18][19]
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.
Beta stimulation: There is evidence that stimulation within the beta range can improve attention, measures of intelligence, relieve short-term stress, decrease headaches, and decrease behavioral problems. Some evidence even suggests that beta could decrease emotion-based exhaustion. Many people with slower frequency brain waves may benefit from regular beta stimulation.
 Theta brainwaves are the next level down from alpha, at a range of 4Hz-8Hz. These brainwaves commonly occur just before sleep, or in the lighter stages of sleep. They also occur while you are day dreaming, or when you experience a strong emotion. It is not so common for an adult to produce prolonged theta brainwaves unless they are an experienced meditator, or perhaps deeply involved in an intuitive art such as music or painting. A dominant theta brainwave state is one of deep relaxation (deeper than alpha) and natural healing. In prolonged dominant theta states, the brain’s sodium/potassium ratio resets and balances itself, curing mental fatigue, and improving the brain cells ability to transport and exchange neuro-chemicals. Without the means of deep meditation, or brainwave entrainment technology, this benefit would only otherwise come from sleeping or napping.Theta is known as the one of the best states for communication with the subconscious mind.
Really great stuff here, man. Well done! Without taking anything away from the article it would have been great to have under one “roof” similar information about hypnotherapy and subliminals. I invested quite a lot in buying binaural cd’s but after reading your material I think that for short term effects isochronic tones rather than binaurals are the technology to go for now. For longer lasting and possibly permanent effects I’m not sure whether I should go for hypnosis or subliminals (or both). An article as well written and comprehensive as yours but focusing on hypnosis vs subliminals would have completed the circle for me. The stuff I’ve read so far on binaurals vs isochronics hasn’t really done it for me. Any chance you could give it a shot?

Sleep improvement: There is significant anecdotal evidence that sleep induction and/or quality may be improved as a result of brainwave entrainment. While it is important to consider the placebo effect or simply the effect of a relaxing sound, many people have reported noticeable improvements in their ability to fall asleep and wake up feeling refreshed as a result of entrainment. Entraining frequencies within the slower wave ranges such as alpha, theta, or delta, may help individuals transition more quickly to those states.
Back in 1839, Dr. Heinrich Wilhelm Dove, a Prussian physicist and meteorologist, discovered that when you introduce tones with certain frequencies into each ear, you could actually entrain the electrical patterns within the brain to resonate in very specific patterns, called brainwave states. The last two decades have seen an amazing amount of scientific interest in this world transforming field of study, laying the foundation for the hundreds of studies conducted since then, boosting the technology’s significance and importance immeasurably.
Going back to the technology, the simple claim of brainwave entrainment is that, by listening to these audios, usually with stereo headphones and eyes closed, your brain will be naturally and effortlessly led into a specific brainwave state as designated by the maker of the audio (ie: it could be alpha, theta, delta, gamma, etc., depending on what the audio is designed to do.)  The other most basic claim is that when listening to these audios, the right and left hemispheres of the brain synchronize and you experience whole-brain functioning.
After nearly two years of daily use of this brainwave meditation and brainwave technology, I began to enjoy a quality of life–without medication–that once seemed quite impossible for me. I do not say this lightly. Not only did I enjoy a fulfilling life, I also experienced what seemed like significant development in self-concept, values, interpersonal skills, creativity, accelerated learning, intuition, ability to handle stressful situations, self-esteem, sense of purpose, and social awareness.
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.

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.

I enjoy this one called: Cognition Enhancer For Clearer and Faster Thinking – Isochronic Tones (Electronic) … I seem to enjoy it. Any harm in just listening to this one every day for 30 minutes as a routine daily thing, just like brushing your teeth and making your bed. I would just use it at times when I’m working at my desk, maybe even reading the online news etc…Thoughts?
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.

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. 
Different states of mind are associated with specific brainwave frequencies that would be inaudible if played directly. These frequencies can be induced in the brain indirectly by playing two different audible tones into each ear, which after being processed by the brain, are perceived as an inaudible beat matching the target brainwave frequency. As you listen, your own brainwaves fall into step with this inaudible beat, and after a few minutes synchronize with the target brainwave frequency. Brain Wave's 35 programs layer these binaural sequences into multi-stage sessions that have helped thousands of people focus and concentrate, feel positive and motivated, and sleep more soundly.

Anyone who has sought out different methods for enhancing cognitive ability will probably have come across a technique known as Brainwave Entrainment. However, it is a fairly niche area of brain training, meaning that this form of stimulation is often overlooked in favour of more mainstream methods. The following outlines what Brainwave Entrainment actually is, how it is used, and some of the benefits attributed to it.

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. 
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.
Theta stimulation: There appears to be no benefit associated with using theta stimulation for cognitive functioning, mood, or stress relief. While theta may be a useful way to induce sleep or alter your state of consciousness, there really isn’t much science supporting entrainment in this particular range for most purposes. Photic stimulation of theta between 5 Hz and 7 Hz can be useful for headaches.
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.
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.
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.
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!
Gamma waves are the most recently discovered brainwave, a discovery made possible by digital EEG technology. Gamma is associated with the integration of information from different areas of the brain, and having a good memory is associated with having a certain baseline of 40 hertz gamma activity. Low gamma activity is associated with learning disabilities and poor memory.
