Business executive and radio producer Robert Monroe started experimenting with brainwave entrainment and has a series of powerful out of body experiences using it. In 1971 he published his cult classic “Journeys Out of the Body” sharing his experiences. He later created one of the first audio entrainment companies called Hemi Sync, alongside the Monroe Institute of Applied Sciences.
I appreciate your compliment on my article Henry. I’ve been using and reading up on isochronic tones and brainwave entrainment for many years, so it was just a case of trying to put a lot of what I’ve learnt into one article. I don’t have a great deal of knowledge or experience in using hypnosis and subliminals, so I’m afraid I wouldn’t be in a position to create something so extensive in reviewing them.
Despite the vast differences between each individual, our brain’s inner workings are remarkably similar. Brainwave Entrainment was built around these fundamental similarities and has equally powerful effects for almost everyone who uses it. While each situation may require a different frequency or audio track, Brainwave Love has one of the most complete, effective libraries to cover your every need. Take a look now:
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.
With so many thoughts begging for your attention each day, it’s hard to believe that most of them are the same ones you had yesterday. Actually, many psychologists who have studied the thought processes associated with our thinking patterns would agree that, on average, 90% of the thoughts that we become aware of throughout the day are the same thoughts that we have already experienced, over and over again. The reason we are so prone to repetitive thinking is because the brain is always … [Read more...]
Until NeuralSync™, brainwave entrainment involved inferior linear, single or sequential protocols - such as binaural beats or isochronic tones - that were natively restricted in their ability to affect the natural complex dynamics of the brain. But now, NeuralSync™ significantly improves entrainment by incorporating EIGHT SEPARATE BUT SYNERGISTICALLY-INTERACTIVE DIMENSIONS into a dynamic and cohesive process powerful enough to compel the brain to produce whole-brain synchronization for intense effect. Incredibly superior to binaural beats or isochronic tones, NeuralSync offers an entrainment experience beyond anything you've used before.
The pitch frequency measures and describes what a beat sounds like, i.e. does the isochronic beat have a deeper bass sound, or is it high pitched and sharper sounding? The beat waveform frequency describes how many times the beat is repeating per second, i.e. how fast it is beating. You don’t really need to concern yourself about the pitch frequency, as that doesn’t have a direct influence on brainwave entrainment and doesn’t play a part on the measurement on an EEG. I only mentioned it because you were referring to humans not being able to hear below 20Hz. I change the pitch frequency just to suit the mood of the track. For tracks that are to be relaxing, for meditation or sleep, I tend to use a lower pitch frequency so it sounds deeper and more relaxing and I never have that lower than 100Hz. For an energizing, high focus track I might use a more higher pitched 200Hz isochronic tone, because that is sharper sounding and less likely to make you feel sleepy. That’s all you really need to know about the pitch frequency.
As somewhat of a modern mystic, I have studied altered states of consciousness, but due to my monkey mind, I have only been able to experience them to a very minor degree. I have tried so many methods of meditation to little avail. But I became aware that I would not be able to progress in my spiritual life if I could not achieve at least a modicum of success in meditation.
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.
NeuralSync™ is the ONLY technology that utilizes FOUR SEPARATE yet synergistically-interactive frequencies precisely calculated to induce each mental state offered in our catalog. Our exclusive 4-W.T.S.P.™ technology creates waves in a balanced 4-dimensional pyramid that are collectively complementary and interactive. Unlike other related programs that use only a single binaural beat or isochronic tone frequency (or several in sequence), NeuralSync™ applies all four simultaneously to immerse your brain into targeted and harmonizing perspectives.
I typically feel overwhelmed by the numerous things that need to be accomplished, which leaves me feeling anxious and rushed. This particular combo has really helped me to slow down today and not feel so uptight, which sadly, is not easily accomplished. I use other modalities to shift my body into parasympathetic mode, but I can't seem to stay there. This program seems to be helping dampen down triggers that cause my body to shift into sympathetic state inappropriately.
Hi there! This is a great question. I think the most important thing to first understand is that in spite of the circumstances you are facing, your stress level and the way you feel on a day to day basis is still within your hands. Happy people are not happy because they have less stressors or challenges in their lives, they are happy because they have learned how to be happy in spite of these challenges. At the same time there may be action you can take to minimize these issues you are facing as well.

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.
"I have been using Quantum Mind Power for two weeks and today I feel that although the changes are subtle, I have been able to overcome many roadblocks in my personal life. I have ADHD and have been taking Adderall for 7 years, recently I decided that I need to stop and have cut my dosage in half with the intention of completely stopping within a month.  I have also just started teaching Pilates as a second job.....

Binaural beats are created from two different continuous tones, which when sent separately to each ear create a single beat inside your head. Isochronic tones are basically a single tone which is switched on and off at regular intervals. Imagine a single continuous tone playing on a stereo system and you’ve got your hand on the volume switch. Then once per second, you turn the volume off for half a second and keep doing that every second. For half a second the volume is off, for the other half a beat waveform is formed. The beat is cycling once per second per second, i.e. at a rate of 1Hz.
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:
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.

The only thing I have found lacking in using your product is that there is no place on your website to register my kudos to you for such an excellent product. I am not new to meditation, nor to brain entrainment products, and I found you product to be really outstanding. I’m completely hooked, love listening to the tracks and they are the best way ever to treat monkey mind. Bada boom, bada bing, in just a few minutes any aggravation I’m experiencing in the outside world, melts away and I am one very blissful and happy camper.


I received my order on Mon. and have done 3 or 4 sessions of Equisync I. I just wanted to say I can already notice a difference in myself. I am much calmer and more clear thinking already in just 2 days. I don’t think it’s my mind playing tricks on me. Is this a common occurrence? Your product is great I can’t wait to try Equisync II and Equisync III.

With almost 100 years of research validating the effectiveness of brainwave entrainment, it’s no wonder why it’s used by thousands of people all over the world. What does the future entail in this exciting field? With the adoption of smartphones, virtual and augmented reality, and advancements in technology reducing the cost of EEG and other forms of biofeedback devices, the entrainment possibilities are endless.

A study by Tina Huang, PhD, and Christine Charyton, published in the September 2008 issue of the journal, Alternative Therapies examined the results of twenty previous studies measuring the effectiveness of brainwave entrainment for improvements in cognitive dysfunction and deficits, stress reduction, pain management, migraine and headache control, pre-menstrual syndrome, and behavioral difficulties, and all showed significant improvement in symptoms using entrainment techniques.


Some people are more sensitive to the audios than others – if you are one of them, be sure to take a break from what you are listening to and come back to it later. Always follow your body’s signals, and don’t hesitate to ask questions. You can always drop me a line for some honest advice on anything related to brainwave entrainment, meditation, holistic health, etc. You can also rest assured that all brainwave entrainment products listed here are of the highest quality – most of them I have used for years. I also highly recommend reading What Is The Best Brainwave Entrainment Product, too.  Don’t feel shy to bother the creators of the products themselves, and their support teams – you are in your full right to do so!
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.
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.
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.

With brain wave entrainment technology, changing brain wave states is an instantaneous and effortless process. The 'periodic stimulus' can be sound, vibrations and/or light. We have found that we get the best results with blinking lights which are experienced through closed eyelids. This is only problematic for people with existing diagnosis of photo-induced epilepsy, as blinking lights can induce a seizure in them. The programs are enhanced with Deepak Chopra doing the narration along with holographic sound effects and original music composed and performed by Rudy Tanzi.
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.
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.
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.
A very pleasurable experience during listening (and often for some time afterwards). As Holosync® changes your brain wave patterns to those of deep meditation, the brain produces several very pleasurable neurochemicals, including endorphins (the same endorphins responsible for “runner’s high”)…as well as several hormones with a profound and positive effect on longevity, aging, stress, and well-being.

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!

Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin.

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.
Recent research at the University of Lisbon finally uncovered the reason for the 350 year-old mystery, finding that the resonance of sound is the mechanism for entrainment of swinging pendulums and ticking clocks, and it seems likely that the energy transferred by sound is also responsible for other observations of entrainment, including brainwave entrainment.
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
Although most experts will tell you that people can get through the day without the production of Alpha brainwaves, that doesn’t mean there won’t be any repercussions. For people who have suppressed production of these brainwaves, they can end up developing anxiety disorders and other stress-related diseases, which can lead to the weakening of their immune system.

Brain Sync Brainwave Technology is the simplest, most affordable way to directly tap into your higher potential and unleash your power to think, create, heal and to change. There’s no training necessary, no need to travel anywhere, or spend hundreds of dollars on complicated home training programs that take up a lot of your valuable time. Just 30 minutes a day will bring outstanding results. When your brain is in balance your ability to think, learn, create and recall is remarkably enhanced. Perception expands, memory improves and you can concentrate more easily. You sleep better and are more resiliant to stress. A balanced brain brings freedom from fear, worry and even addictions that have stood in the way of you experiencing more fullfillment and joy.
In 1956, the famous neuroscientist W. Gray Walter published the results of studying thousands of test subjects using photic stimulation, showing their change in mental and emotional states. He also learned that photic stimulation not only altered brainwaves, but that these changes were occurring in areas of the brain outside of vision. In Walter’s words:
Brainwave entrainment music can be used almost anywhere and anytime, making this mood and self-improvement method versatile and flexible enough to do at work, while traveling, or at other times during the day. When used in the workplace during short rest periods, brainwave entrainment techniques can enhance concentration, communication, and work productivity.
Hi Jason, thanks for all the uploads to youtube. I’ve been using them in work recently to help me concentrate and relax. I like the music tracks that you’ve chosen to overlay the tones. A couple of times in the last 2 weeks I’ve experienced the wavy pulse like sound, similar to the tones in my left ear. I wasn’t listening to tracks at the time or that day. It doesn’t last but it feels a bit strange. I wondered if I might have been listening to the tracks too loudly and that it was almost like a type of tinnitus. I’m curious to know if anyone has been in touch with you in the past to say they’ve had a similar experience?
While binaural beats are the most common technique we use for producing brainwave entrainment music, we do use other brainwave entrainment techniques such as isochronic tones, monaural beats and amplitude modulation. If these techniques have been used then you will find them mentioned in the written description of the music productions that include them. If not mentioned, then you can assume that binaural beats are the only brainwave entrainment technology in use.
Years of scientific study combined with the personal testimony of thousands of people establish that using brainwave entrainment techniques positively affects the physical, mental, emotional, and spiritual well-being in a majority of users. You can easily take advantage of these powerful methods of personal self-help and self-improvement by downloading a variety of entrainment music right now.
Entrainment is a phenomenon seen is a wide variety of different natural circumstance. In the field of chronobiology, the study of biological rhythms in living organisms, entrainment is the synchronization of a circadian rhythm with the rhythm of an external pattern, such as the synchronizing of women’s menstrual cycles with the phases of the moon or with one another in a group.

I’m sorry to hear you’re having these troubles. First off, I disagree with whoever told you it was a good idea to listen to 6 subliminals a day. I suppose I would need more context to better understand. Are these binaural beats or brainwave entrainment audios? If so you are definitely listening too much, and can harm yourself (just as the article mentions above from over-doing it). Even if they are not brainwave entrainment audios, I cannot imagine it is effective or the best idea to listen to so much so often. I would pick one subject that correlates to the most important goal for you and stick with it until you have achieved it. Remember to steer clear of that tempting idea of getting “all that you want for nothing”. Even subliminals are a tool. You still have to use the tool to do the work.


One of the more fascinating aspects of what brainwave entrainment does, long-term, is the growing of your mental threshold, and your self-awareness.  I have been a participant of the Holosync Solution for several years, and its maker, Bill Harris, has gone to great lengths to explain why this technology does this.  Much of his research is based on the concept of Entropy and Open Systems, (an idea that nominated its discoverer for a nobel prize).  The brain being an open system, and the technology being a specific type of entropy, this technology has been shown to help the brain reorganize itself at a “higher level” through the growth of new neural pathways. This basically means that 

A few months ago I decided to test the ability of the “Equisync II” brainwaves therapy combined with other more traditional self-improvement programs and the results have been even more amazing to me. Currently in my mind I honestly believe this type of therapy can be a breakthrough, or simply the genesis of a new type of therapeutic techniques to correct several psychological, and behavioral human issues including depression, lack of organization, and self-esteem among many, many other possibilities.

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.
Want to use it as a serious tool for self-development, long-term meditation support, etc.? Find a supplier that is in alignment with your own values and knows what they are doing. E.g. Holosync have decent entrainment technology, but make ridiculous claims and are very salesy and pushy...  I have tried several and always come back to the Monroe Institute and their well tried and tested sessions, mainly from the gateway experience and lucid dreaming series.
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.

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.


With digital upgrades, Berger’s machine is still in use today, known as an electroencephalography machine, or EEG. Berger used his machine to study the brains of psychologically normal and abnormal people and discovered the first brainwave, called the alpha wave and also known as the Berger wave, along with the faster beta wave, which he observed suppressing the alpha wave when subjects opened their closed eyes. 
 It is a good idea to follow any instructions outlined by the makers of any type of brainwave entrainment product or program, and to ease yourself carefully into using it. If experiencing any negative side effects, take a break and come back to it later. Brainwave entrainment audios are not recommended for children under the age of 18, and should not be used while driving or operating heavy machinery.

When making an educated decision on what product is best for you, it is important to have a general understanding of how the technology works, and what the benefits are of visiting the specific brainwave states.  Please click the link to visit a more detailed article –  How Does Brainwave Entrainment  Work, and the benefits of Alpha, Theta, Delta, and Gamma brainwaves.
“A quite different phenomenon results when stereophonic earphones are used and the signals are applied separately to each ear. Under the right circumstances beats can be perceived, but they are of an entirely different character. They are called binaural beats. . . . Binaural beats require the combined action of both ears. They exist as a consequence of the interaction of perceptions within the brain.”

Gamma brainwave states are the most rapid in frequency. Gamma has long been considered the brainwave that is able to link and process information from all parts of the brain. It is the frequency that brings with it the ability to process large amounts of information in relatively small amounts of time. Think of generating more Gamma activity as getting a processor upgrade for your brain.
- 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.
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.
When you listen to binaural beats/tones, you are actually listening to two slightly different pitched frequencies. Each frequency goes to each of your ears independently. When this happens your brain responds by creating a third tone, making up the difference between the two frequencies. This shift in frequency then shifts your brain’s consciousness and changes your state.
In the 1980s, a researcher in Japan, Tsuyoshi Inouye described how light stimulation creates synchronization of brain hemispheres. Since then, other researchers have detailed the positive effects of hemispheric synchronization including a 1984 study by researcher Dr. Gene W. Brockopp stating that hemispheric synchronization resulted in improved intellectual functioning as well as improvements in long-term memory, and these effects are cumulative over time.
Well, I finally listened to “Equisync III” after listening to “Equisync I” & the “Equisync II” several times. Let me just say that this put me in another state of consciousness within 7 minutes(guessing) it was beautiful! I meditated throughout the entire 70 minute CD set! It didn’t feel like 70 minutes. I could feel energy in my neck, my solar plexus area and at the brow of my head! Definitely NOT for beginners!
The authors concluded that preliminary evidence suggested that brainwave entrapment was an effective therapeutic tool, but further research was required. The evidence presented appeared to justify the recommendation for further research. In view of the lack of controlled evidence and problems with methodology and reporting in the review, the authors’ conclusions regarding efficacy did not appear reliable.
