One RCT (n=108) showed significant reduction in anxiety from a single session of alpha/delta therapy for day surgery patients. A crossover RCT of a single session of theta stimulation in four healthy adults reported significant improvement from the intervention in one of five measures. Five pre/post studies reported significant benefit from the intervention for 16 of 27 outcomes.
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.
- 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.
Subsequently, the term 'entrainment' has been used to describe a shared tendency of many physical and biological systems to synchronize their periodicity and rhythm through interaction. This tendency has been identified as specifically pertinent to the study of sound and music generally, and acoustic rhythms specifically. The most ubiquitous and familiar examples of neuromotor entrainment to acoustic stimuli is observable in spontaneous foot or finger tapping to the rhythmic beat of a song.
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.
“Binaural beats are not very noticeable because the modulation depth (the difference between loud and quiet) is 3 db, a two-to-one ratio. (Isochronic tones and mono beats easily have 50 db difference between loud and quiet, which is a 100,00-to-1 ratio). This means that binaural beats are unlikely to produce an significant entrainment because they don’t activate the thalamus.”

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!
Recently developed entrainment software has been designed to correct specific imbalances in hemispheric activity associated with undesirable mind-states. For example, people suffering with depression often have more activity in the right hemisphere, and specially designed brainwave music decreases this activity while increasing activity in the left hemisphere, reducing depression.
The phenomena of brainwave entrainment was first described in the scientific literature in 1973 by Gerald Oster in results published in an article in Scientific American entitled, “Auditory Beats in the Brain”. He showed that a specific brainwave could be induced when a person heard two separate, but closely related, sound frequencies, one in each ear. He discovered that when the frequencies heard by each ear differed by about 10 hertz, the brainwave pattern of the person hearing the sound would synchronize to the difference between the two frequencies. For example, if the person heard a 410 hertz sound in one ear and a 400 hertz sound in the other ear, their brainwaves would stabilize at the difference between the two, or 10 hertz. This technique is called binaural beats, and it is a fundamental principle of brainwave entrainment methods.

In simplest form, they are an audio technology which are used for (safe) brainwave entrainment. Our subconscious mind operates, throughout the day and night, in various brainwave state frequencies, measured in cycles per second (Hz) These frequencies range from the slowest (Delta) frequencies experienced in deep, dreamless sleep and in deep meditation where your conscious-awareness is fully detached, to the fastest (Gamma) frequencies associated to stimulating flow states, high-level thinking and information processing. There are actually 5 known brainwave state frequencies each having their own set of unique characteristics:
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.
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.
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?
my daughter had an EEG and the neurologist said the brain wave activity in the back of her brain was very slow. I want to find out what causes this. She had a brain injury (3 skull fractures that were in the right side of her head and across the front right side. The fractures were closed wound. She had a small amount of swelling which diminished on it’s own. The neurologist asked if the fractures were in the back of her head and I told her no. She had no explanation for me.
The brain produces electrical signals. These signals change depending on what we are doing and what mental state we are in. For instance when we sleep these signals are different from when we are awake. This brain activity can be measured with EEG. It will output in Hz (Hertz - cycles per second) these electrical signals. The most dominant brainwaves will tell us what sort of state a person is in. The slower vibration (lower Hz), the more relaxed that individual is. Using audio technology we get the brain to start following the beats or pulses in a sound if done exactly right.
My voice is relaxing and relaxation is pleasurable. These mental directives soothingly lull your conscious mind into ending its internal dialogue. It is the conscious mind that does ALL of the worrying, nagging, second-guessing and basically all of the incessant mental chatter and constant inner dialogue that can keep us trapped by our own view of reality, whether these views are good for us or not.

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.


Meanwhile, the therapeutic benefits of listening to sound and music is a well-established principle upon which the practice of receptive music therapy is founded. The term 'receptive music therapy' denotes a process by which patients or participants listen to music with specific intent to therapeutically benefit; and is a term used by therapists to distinguish it from 'active music therapy' by which patients or participants engage in producing vocal or instrumental music.[37] Receptive music therapy is an effective adjunctive intervention suitable for treating a range of physical and mental conditions.[38]
