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. 
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.

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?

Deeper Meditation • Near The Stage Of Sleep • Vivid, Dreamlike Imagery • Creative Visualization • Feel More Open & Connected • Advanced Problem Solving • Super Creativity • Insight • Intuition • Inspiration • Deeper Subconscious To Super-Conscious Mind • Trance-like • GABA • Immune System • Serotonin • Endorphins • Acetylcholine • Lower Cortisol • Deeply Relaxed • Sleep Better • Emotional Intelligence


A popular opinion in the brainwave entrainment community is that listening to isochronic tones without music produces a much stronger effect.  However, in the study by Doherty, Cormac. “A comparison of alpha brainwave entrainment, with and without musical accompaniment” (2014),  it was concluded that brainwave entrainment was equally effective for isochronic tones, both with and without music.

I definitely NEED (& can feel a difference mentally) Gamma the most. Beta and Alpha do better my processing. Theta waves are TERRIBLE! My normal symptoms increase when listening to those frequencies! Delta has been helpful for me around nighttime. It has helped my sleep on occasion. *Note: Do not listen to higher frequencies (Gamma, Beta) before bedtime! They will keep you very alert.
So using the example track above, the right ear is sent a 20Hz beat, compared to a 10Hz beat in the left ear.  As the right ear receives the higher frequency of beat, this works to increase the speed of the ‘left' brain hemisphere, which can be helpful for people with conditions like ADD, who are often found to have an abundance of slow wave activity in the left brain.
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.
But again, when it comes to subjective experience, and mental evolution, I would have to caution you to take what anyone says with a grain of salt.  Obviously people want to sell these products.  There are some good ones out there and there are some bad ones out there.  There are differences in quality, as well as differences in intent with how the audios are to be used.
Stress: In one randomized controlled trial with 108 participants, a single session of alpha and delta stimulation resulted in significantly less anxiety in surgical patients. Another session of theta stimulation resulted in improvement in certain measures of stress. Stimulation with certain frequencies of alpha and beta were reported to provide the most significant benefit for those who are stressed.
For me, brainwave entrainment actually helped me more easily meditate on my own without the technology. There is definitely evidence to suggest that the neural pathways that form from listening to these audios aids the brain in better producing these brainwaves on its own moving forward. Though I used brainwave entrainment for several years, almost daily, there was also a point in my life where I went without the technology and meditated daily on my own. I believe that even this practice was accelerated drastically by my listening to bwe in the past.
I also believe that the dangers of brainwave entrainment should be further explored as well. There are relatively vague benefits, but it remains unclear as to whether entraining certain frequencies may be detrimental to performance or induce harm. Despite the fact that brainwave entrainment has existed for a long term, it remains an understudied niche in neuroscience.
I just wanted to thank you guys for having such an outstanding product available. I used to meditate when I was younger but got away from it over the last 7-8 years. I had difficulty starting back up, but since I started using your cds I have no difficulties getting back into it; and am now meditating 2 hours per day and have never felt better. I have only been using them for a couple weeks but have already noticed a difference. Thanks again for creating such a wonderful product and I will be sure to recommend it to everyone.
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.

Because each track is specifically aimed at attaining a certain outcome, you can pick exactly which track you want for what you want to do. This is great for beginners because you can start off with some simple tracks such as Instant Energy Boost or Endorphin Release. And then if you find you like them you can choose some of their more hardcore stuff (such as Lucid Dreaming or Shaman Consciousness).


Admitted, I haven’t listened to all the tracks yet, but while listening to the demo alone over the course of a month-and-a-half I, too, had a transcendental experience that was amazing! So I determined pretty quickly to save the money and buy your product, even though I really can’t afford it. Yes, over the last 3 years meditation has become that important to me.

Binaural beats can be experienced in any float session you book.  To this point in your floating practice you may, or may not, have heard of – or perhaps already experienced – binaural beats and their effective use of being a unique option/tool to listen to while in (or out of) the tank. But what exactly are binaural beats, how do they work and why choose to listen to them? All good questions, so here we go:
Thanks, this was the kind of article I was looking for. I most have gotten over excited as I read a post about a guy who had major success with 40hz binaural beats. I wanted to make my own experiment, but I see now that I will need to continue my research and gather more background information. Maybe one should have his physiology examined? In order to have a professional opinion on whether or not it will be altered or damaged by use of brainwave entrainment (Maybe you happen to be a very vulnerable individual). Getting trustworthy guidance from an experienced source would also be nice 🙂
How it works: Brain Wave synchronizes brainwaves with a specific frequency by sending two different audible frequencies to each ear, which, after being processed by the brain, are perceived as an inaudible low frequency beat matching the target brainwave frequency. Various states of mind are associated with different inaudible brainwave frequencies, ranging from an alert and focused state of mind to deeply relaxed, all the way to deep sleep, and can be induced with this technique.  Brain Wave recreates these frequencies using the most advanced multi-stage binaural sequences available, allowing your mind to relax and synchronize with your desired state. It achieves this using a unique process called progressive brainwave entrainment.
Dissociative but not present. In college I started having difficulty with reading comprehension/absorption (not dyslexia, I could read everything out loud easily but not gather the meaning). Over the past two years or so, my memory has been concerning, as I am not middle or late aged. Since it had been getting worse, I have been researching for several years now for a cure. Biofeedback led me to neurofeedback (which I can’t afford at the moment).

The benefits of brainwave entrainment have been debated by numerous experts and, after multiple sessions of observation, the following effects were identified. First, the beats were seen to assist in meditation with the use of low frequencies such as Alpha, Delta and Theta, triggering a sense of relaxation that ultimately allows undisturbed meditation.
Audio-Visual Entrainment (AVE) is a technique that utilizes pulses of light and sound at specific frequencies to gently and safely guide the brain into various brain wave patterns. By altering your brain wave frequencies, you have the ability to boost your mood, improve sleep patterns, sharpen your mind and increase your level of relaxation, all with the simple push of a button!
I would like to start off by saying that many bold statements are made about this technology from people who have a self-interest in promoting or rejecting it. We have to face the truth by accepting that people are profiting from brainwave entrainment, and as a result of this other groups of people are being affected in a negative way (from a business point of view). This is a reason why you can find all kinds of claims from someone who has never used or tested the technology.  Unfortunately I have found in my own personal journey of using brainwave entrainment that there are some great people out there making some great products, and there are also some irresponsible and untrustworthy people out there trying to grab a slice of the pie.
I also believe that the dangers of brainwave entrainment should be further explored as well. There are relatively vague benefits, but it remains unclear as to whether entraining certain frequencies may be detrimental to performance or induce harm. Despite the fact that brainwave entrainment has existed for a long term, it remains an understudied niche in neuroscience.
I have received many requests for live sessions and personal support via telephone and video chat (Skype or Facetime). I am proud to announce that you can now schedule your own appointments with me for personal consultations, hypnosis sessions or any general counseling, questions or concerns about your specific needs, life coaching, self-help issues, dream guidance, spiritual matters or just random questions about consciousness or reality in general. I look forward to speaking with you on the phone or video chatting via Skype or Facetime.

- Added the ability to create a playlist of your own iTunes library music and use it as background. The behavior of the app with iTunes music is used instead of, or combined with our included ambience, is slightly different so please review the help. Notably, unlike our included ambience which can be played at a volume below the device volume, iTunes audio can only be played at the device volume. So when in iTunes mode the Ambience volume slider disappears.


The mechanism for this is that when your eyes or ears are exposed to a particular frequency of pulses or beats, the thalamus first distributes this information to the entire brain, including the visual and cerebral cortex where neural activity begins to synchronize to the incoming frequency, producing hemispheric synchronization and a balance of brainwave activity across the brain.
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).

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.

If anybody would like to look over the scientific evidence concerning brainwave entrainment and isochronic tones, I’ve done a lot of research over the years which I’ve collected at the PubMed website of NCBI – a branch of the National Institute of Health – that provides access to a large library of medical journal articles. I’ve made my list public so you can look through the journal articles that were published concerning this topic. Here’s the link: http://www.ncbi.nlm.nih.gov/sites/myncbi/1tmDFOl0XtyA4/collections/51531796/public/. Most of the collection only gives access to abstracts or summaries unless you’re at some kind of educational institution that has a subscription to the particular journal that article is in, but I actually find abstracts really helpful. So have at it, read away. And if your psychiatrist/therapist thinks you’re nuts for feeling better after listening to isochronic tones, just whip out your 82-page collection of scientific journal abstracts written by her peers and give it to her to read. 🙂

Hi EJ, at the moment, there hasn’t been any research to give an indication of how long you should or shouldn’t listen for. Over time, I’ve seen people use my tracks for longer and longer. I started off providing 30-minute study tracks, but through demand, I extended them to 3-hours. I know from the many thousands of comments I’ve had on YouTube that a large number of people play those 3-hour tracks on repeat, or listen to different ones, one after the other throughout the day. I’ve also seen apps where you can play tracks like mine on continuous repeat. So it’s common for people to listen to them all day while they are studying.
Every NeuralSync™ audio is recorded with full-range frequency sweeps that cycle rhythmically throughout the entire audio. The dynamics of the sweep are then additionally enhanced with simultaneous left-to-right channel crossing. Because of this augmentation, the effects are multiplied, the intensity is amplified and the brain is drawn into the mental state more consistently and powerfully than with the static methods of other protocols.
The brain will entrain to the strongest stimulus. If you combine binaural beats with isochronic tones, your brainwaves will entrain to the isochronic tones. If anything, when you combine the two I believe it makes the track less effective because it makes it harder for the brain to decipher between the two and synchronise to a single beat. There are lots of websites with compelling marketing about the benefits of combining the two together in some funky way, but I haven’t seen any research or lots of anecdotal feedback even to suggest it’s effective to combine them.
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.
I later learned that a Nobel Prize-winning scientist, Ilya Prigogine, had developed a theoretical model regarding the evolution of complex systems (like the human mind) that described these quantum leaps in awareness and brain-power I was experiencing—to a “T”—and explained why they happened! I read everything I could get my hands on about his work.
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…
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.
This is probably the most popular choice of frequency. The theta state is a state of tremendous stress relief. The benefits associated with theta level relaxation include improved concentration, reduced hyperactivity and improved memory. While in a state of theta relaxation, one’s blood pressure, breathing and heart rate all slow to a much more restful and healthy level that promotes natural healing. During theta relaxation one may also experience vivid flashes of mental imagery as the mind opens to memories or subconscious information that is not available to the conscious mind during the normal waking state. The theta state is a very deep state of relaxation that is excellent for deep hypnosis and mental programming.
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.

AVE is capable of producing situationally appropriate brain wave frequencies through the process of entrainment (the tendency of physiological processes to mirror environmental stimuli). AVE also increases cerebral blood flow (blood flow in the brain) and increases the metabolization of glucose in the brain for improved functioning of the neurons. The combined outcome of these processes is improved mental performance. It is an effective, inexpensive alternative therapy for many disorders such as anxiety, Attention Deficit Disorder (ADD), Seasonal Affective Disorder (SAD), PTSD, Fibromyalgia and chronic pain. Our AVE devices are also used successfully to boost physical performance for athletes, academic performance for students and cognitive performance for seniors.

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?

True on your point about diminishing returns. It is like dieting. The bulk of the weight comes off at the beginning and then you lose a pound or so if you are diligent. Yes you lose the high of the original gains but you don’t receive more gains because you are in a better place. I am a big believer in data. When the gains begin to be less obvious a daily entry of how your emotional state was (1-10) and naming something you are grateful for goes a long ways. I guarantee a person will overall be in a better place on average. As always, thanks for your contributions Daniel.
1. Compressed formats like MP3 do not retain the sound quality necessary for the brain to fully achieve brainwave synchronization – and are too inferior to effectively deliver even binaural beats downloads or isochronic tones properly, much less something as powerful as NeuralSync™. Our lossless audio entrains at the precise level guaranteed to induce the most potent response.

Since most of us spend our days in the beta state, EquiSync excludes the beta brainwave frequencies, and entrains only those responsible for the most beneficial brainwave states: alpha, theta, and delta waves. The two charts on this page illustrate the basic benefits of each brainwave state as well as the basic targeting of the EquiSync programs 1, 2, & 3.

“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.”
That is a general assumption people make but there isn’t really much science to back it up. What we do know though is that isochronic tones are ineffective below 4hz, and possibly a bit higher. So for theta and delta entrainment you are best off with binaural beats. In my experience binaural beats will be very effective all the way up to around 40hz.
Entrainment is a term originally derived from complex systems theory, and denotes the way that two or more independent, autonomous oscillators with differing rhythms or frequencies, when situated in a context and at a proximity where they can interact for long enough, influence each other mutually, to a degree dependent on coupling force, such that they adjust until both oscillate with the same frequency. Examples include the mechanical entrainment or cyclic synchronization of two electric clothes dryers placed in close proximity, and the biological entrainment evident in the synchronized illumination of fireflies.[13]
