Sensorimotor rhythm (SMR) is one final type of brainwave that has been studied. SMR, also known as low beta, is a type of brainwave, which occurs in the sensorimotor cortex, in the 12 to 15 hertz range when that area of the sensorimotor cortex is idle and immobile. The purpose of SMR brainwaves is not well understood, but some neurofeedback practitioners report training to increase SMR brainwaves can be beneficial for people with autism, epilepsy, ADD, insomnia, drug addiction, and as an aide to better manage stress.
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.
Another small scale study with 30 children were entrained with a starting frequency of 14 Hz and ramped up to 40 Hz. Following the excitatory-based protocol, they were then given a protocol that started at 40 Hz and decreased to 14 Hz over 6 weeks. The results indicated that the children significantly improved in arithmetic abilities based on the WISC-III.

When I am using equisync I feel kind of like it is “pushing me” – I guess this is the right way to say it- to achieve better results, which I really like. I fall asleep quickly, and sleep all night and even wake up before my alarm goes off. I feel noticeably calm during the workday- which is very helpful for what I do. I really like the warm feeling (my whole body gets really warm during my equisync meditation sessions) and I feel kind of like Im floating while listening. The soothing rainfall is also very nice.
Hi Amandeep. I am so sorry to hear you are having these troubles. I am not familiar with Marisa Peers materials, so I cannot comment on this, but I can tell you we have never had an experience like this reported from using the audios we offer on this site. I would cease any and all hypnosis or brainwave entrainment audios, and contact your doctor. The issues you are mentioning sound like they could be a physical issue that may be related to more than the audios you’ve listened to.
Research shows that parts of the brain and eventually large areas of the brain begin to resonate sympathetically with this "phantom" binaural beat. This is known as the Frequency Following Response. Subsequent research determined that a binaural beat frequencies drive brain activity into specific brain states. Thus, effortlessly and naturally, your brain activity slides into rhythm with this binaural beat, becoming organized and coherent. Within minutes, the sound frequencies start to balance the left and right hemispheres of your brain – creating a remarkable state called hemispheric synchronization and driving the electrical activity of your brain into powerful states, normally unattainable. Flashes of creative insight, euphoria and a deep sense of calm is often accompanied by this extraordinary brain state.
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.
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.
Mood: While brainwave entrainment may not be a great option for depression, particularly in the slower frequency ranges, beta entrainment may improve certain measures of mood. Additionally it is important to consider the fact that many people experience detrimental changes in mood as a result of heightened stress and anxiety. Since brainwave entrainment has been shown to improve stress and relaxation, overstressed individuals may experience a simultaneous mood improvement.
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.
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.
Hi Pajaro. It is difficult to pinpoint exactly why and they probably didn’t want to make assumptions without conclusive evidence. Do you suffer from ADD? Or do you struggle to focus? The reason I ask is because of this: “Peak performers’ decrease Delta waves when high focus and peak performance is required. However, most individuals diagnosed with Attention Deficit Disorder, naturally increase rather than decrease Delta activity when trying to focus. The inappropriate Delta response often severely restricts the ability to focus and maintain attention. It is as if the brain is locked into a perpetual drowsy state”. This extract… Read more »

Our state of mind, mood, energy level, motivation, and overall well-being all emerge out of the electrical energy produced by our brains. Do you want more control of your moods and thoughts every day? If so, brainwave entrainment is a method which greatly assists many people in finding greater relaxation, better moods, and less anxiety in a way similar to how music uplifts and rejuvenates us, and brainwave entrainment techniques are available embedded into musical arrangements, giving you the benefits of both modalities.
When blended with musical sounds, brainwave entrainment frequencies induce specific states of mind, which are the result of those brainwaves, delivering them in pleasing and relaxing audio tracts for use with and without stereo headphones. For example, alpha and theta waves, because they exist at the borders between conscious and unconscious thought, are especially rich and useful for tapping into and stimulating subconscious processes.
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.
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.
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.
Because of the way they are created, there may be a positive benefit from listening to binaural beats without considering the brainwave entrainment aspect, but I haven’t seen any research on that. I first discovered brainwave entrainment through binaural beats about 10 years ago now, but they didn’t do anything for me. So I’ve never been a regular user of them. I believe isochronic tones are a more effective way to produce hemispheric synchronisation because they produce a much stronger response in the brain
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!)
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.
Beta brainwaves are next highest in frequency after alpha waves, occurring at 13 to 30 hertz. Beta brainwaves are what we experience every day as we are awake and using our analytic mind. Beta brainwaves are needed for concentrating on mental tasks, and when they are present for too long of a time, they lead to stress, anxiety, and even paranoia. Most people do not have trouble achieving beta brainwaves and in fact suffer from spending too much time in beta brainwave patterns. However, those with attention deficit disorder (ADD) who have problems focusing their attention can benefit from learning how to achieve and remain in beta brainwave states for longer amounts of time.
Tracks that move from alpha to theta can be a perfect vehicle for transitioning from a hectic day into a relaxing and rejuvenating sleep. Beginning with alpha waves takes you into a light but still alert meditative mind state where the difficulties of the day can be resolved and put to rest. Later, theta waves go deeper into the unconscious, preparing you for sleep and dreams.
But here is where I’d like to chime in my own two cents.  As a user of brainwave entrainment products for over 8 years now, you would obviously have to guess that I think this technology is fabulous.  Even my earlier experiences with brainwave entrainment technology using less refined binaural beats were nothing short of miraculous for me.  It’s a very fascinating experience to go from not being able to meditate at all to being able to sit with your eyes closed and headphones on and effortlessly slip down into deep brainwave states that were previously only reserved for years-long experienced meditators.
So, what is binaural beats or binaural tones?  They are auditory (hearing) processing artifacts, or apparent sounds, caused by specific physical stimuli.  This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.

Absolutely. Binaural beats were first discovered over 150 years ago, and their use in brainwave entrainment audio has been the subject of a great deal of scientific exploration over the last 35 years in particular. Millions of people use brainwave entrainment music to enhance their quality of life and to experience deep relaxation. In fact, brainwave entrainment technology is now used for more than just meditation. It is also used by a variety of practitioners and private users for improving self-confidence, stress relief, pain management, relaxation, improving and concentration and improving the quality of one's sleep. If you would like to read an objective third party report on binaural beats, please refer to this Wikipedia article.


Scalar waves are a constantly regenerating energy source that imprint a signature on your body with lasting positive effects. They strengthen chemical bonds within DNA, making it more resistant to damage and cleanse blood and cells to improve immune function. They impart energy that helps mental focus, and increase amplitude of all EEG frequencies, but particularly the lower levels where deep rejuvenation, relaxation and healing occur. They leave you feeling refreshed and energized, with lasting pleasant sensations that continue long after each brainwave entrainment session.


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
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.
When delta waves are present, our awareness of the external world decreases and shuts off. People with ADD have problems with delta waves occurring when they are trying to focus, and focus and attention become increasingly impossible with stronger delta waves. Studies show a reduction of anxiety, improvements in insomnia, and elimination of headaches when people engage in sessions of delta brainwave entrainment.
In March I started using the CDs that I affectionately call “Meditation for Dummies” and am very pleased with the results so far. My blood pressure has dropped, I am sleeping better and notice that I feel much more calm and less stressed. Instead of feeling that I need to “find the time” in my schedule to meditate, I look forward to that totally relaxing half hour–that peaceful feeling of floating.
So often it is presented as such a highly scientific technology that can only be created by “experts”. Buzz words like “scientific”, “certified engineer”, “frequencies”, “cortical evoked response”, “anterior brain activity”, are used to make it seem over-complicated, and pseudo-scientific pictures of “data” and “brain readings” are pasted all over sites to further qualify claims of how powerful and amazing these people’s product is.

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.

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.
