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]
There are many sources of binaural beats on the internet and YouTube to check-out and experiment with yourself – I recommend using headphones for optimal effectiveness. However, like most things, not all binaural beats are created equally (especially if they are free on the internet) and therefore not as effective or enjoyable to listen to. This is why I HIGHLY recommend the binaural beats created by master audio technician, music producer and meditation teacher, Cory Allen – which can be found here:

Robert Monroe, a radio producer and executive published a popular book called Journeys Out of the Body about his out-of-body experiences when using brainwave entrainment. He later founded an original brainwave entrainment audio company, Hemi Sync. In 1981, the book Mega Brain by Michael Hutchison brought brainwave entrainment information, techniques, and terminology into the popular press.
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.
What I really like about iAwake is their standalone offerings. They produce quite a few audio pieces that are geared toward specific brainwave targets and desired results. These individual products aren't progression - based (you can listen to whatever tracks you want whenever you want), so there's no lengthy investment of your time involved. Also they're way cheaper (around $30-$50 depending on the product). In addition to manipulating brainwaves with sound, they pride themselves on their patented Biofield tech (look them up for more info).
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. 

But especially at this point, I’m on a mission to get as many people using Holosync® as I possibly can—my current goal is 100 million Holosync® users. Because we already have so many people using it, the economy of scale allows me to offer it to you for MUCH less than what my accountant suggested: just $179 if you’d like Awakening PrologueTM on CDs… or $159 if you want the downloadable MP3 version…

Hemispheric synchronization: Whether it’s optimal or suboptimal to operate in a state of hemispheric synchronization remains unknown. Some speculate there are numerous benefits of brain waves operating in “sync” as a result of entrainment. There may be an increased communication between the right and left hemisphere of the brain – which could improve certain functions. However, it is also important to realize that increased hemispheric synchronization may not be as beneficial as many have speculated.
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.
“…humans have always been intrigued by the possibilities for influencing mental functioning that emerge from combining rhythmic sound and rhythmic light stimulation. Ancient rituals for entering trance states often involved both rhythmic sounds in the form of drum beats, clapping, or chanting and flickering lights produced by candles, torches, bonfires, or long lines of human bodies passing before the fire and chopping the light into mesmerizing rhythmic flashes. From Greek plays to Western opera, our most popular entertainment forms have made use of combinations of lights and sounds. Some composers, such as the visionary Scriabin, actually created music intended to be experienced in combination with rhythmic light displays.”
“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.”

I’ve been using equisync first thing in the morning after I get up, and listen to all three tracks in a row. I again listen to all three tracks in the late afternoon. If I don’t have that much time available, I will start on Track 2 or 3, as necessary. I have really started to focus on my breathing, and notice the difference – I finish the session in a DEEPLY relaxed state.
The results of using EquiSync for only 3 months have been phenomenal! Profound and positive changes have occurred , and continue to occur, in my being. These transformations have become obvious to family and friends as well. I am 71 yrs old and feel better than when I was in my thirties. My energy levels remain high with less sleep. I work out at the gym vigorously five days a week – bicycling and swimming are part of the regimen as well. I volunteer services at Hospice and nursing homes. My short term memory has improved to the point that others remark on my remembering their names after meeting them only once several weeks in the past. Sometimes I find that I’m reading fine print without my glasses. I spent the greater portion of my “productive” years as a monk but had lost the ability to meditate due to the development of A.D.D. Now my ability to stay focused and concentrate has remarkably returned and am reaching meditative states that I’ve not reached in years. Each new day is now seen as another opportunity to serve.
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?
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.
2. Dimensional sound insures that the brain perceives the entrainment as more realistic, which produces more natural and thorough engagement in each meditation. Not only does this create more pronounced effects and an intensified response, but it also avoids the fatigue generated by overuse of standard sound – as can occur with extended use of other audios.
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.

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.

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! 

Many psychologists, doctors, teachers, and other professionals have endorsed the technology while personally taking advantage of the limitless benefits that accompany EquiSync's precisely designed brainwave synchronization/ entrainment technology. It is such a profound field of study that many of the metaphysical benefits, those beyond our current scientific measure and technological & philosophical understanding, have yet to be discovered.

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.
How does brainwave entrainment work? Consistent, precisely engineered audio frequencies in the form of binaural beats cause the brain’s frequencies to match the stimulus. Your brain perceives two beats with slightly different frequencies (which are inaudible to the ear) through your headphones. It takes the difference between the two, and matches its own frequency to it. This is called the “frequency following” response.
