Brainwave entrainment also happens with the use of pulsating light, and visual and auditory stimuli are sometimes combined for additional effect and visual stimuli is used alone. Using brainwave entrainment techniques is safe for almost everyone, the exception being pregnant women and people who have seizure disorders who should check with their physician before using these methods.
Insomnia and PTSD for most of my life are real bears that I wrestle with every night. A brain neural-therapist (for lack of a better description) said that this kind of sound recording may help. It is not music. When I remember to play the disc, I fall asleep within the first 5-8 minutes. One day I played the disc while cleaning and I was very surprised to hear how much of the recording I never recall hearing before. That's why I know how long it takes to fall asleep.
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.
Theta waves have a frequency between 4 and 7.5 hertz, making them slower than more wakeful alpha but faster than the dreamless slumber of delta. Theta brainwaves are the frequencies of nighttime dreams and REM sleep when the brain goes through bursts of activity and eye movement. People also experience theta waves in a state of light sleep, deep relaxation, during meditation and prayer, and when daydreaming. Theta waves produce an experience of inward wakefulness where we become disengaged from the outside world while engaging in inner activity. At the lower frequencies of theta, sleeping states are experienced, and at the higher range of frequency, awake relaxed states are experienced. 
Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.
Most programs start at a work/life busy brain Beta frequency of twenty light flashes per second (20Hz) and slowly ramp them down to Alpha (relaxation and meditation) at 8-12 HZ, Theta (deep relaxation and dreaming) at 4-8 Hz) and Delta (dreamless deep relaxation) of .5-4Hz. We have taken measurements at Mass General with state of the art EEG equipment and have seen a slowing of the brain waves from Beta to Theta in two minutes and complete brain wave harmonization in the left, right, anterior, posterior and occipital regions of the brain.
Initially the children were entrained to a mu-alpha rhythm (7 to 9 Hz) to decrease theta waves. After the initial mu-rhythm entrainment, they entrained SMR-beta waves for 22 minute sessions. The results as interpreted by TOVA demonstrated significant improvements in: inattentiveness, impulsivity, and variability. Teachers and parents also reported behavioral improvements among the children. Using the right brainwave entrainment protocol may be a potential Adderall alternative for those with attentional deficits.
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 
First of all thank you for your amazing website, I have a question regarding these matters, I can make both binaural beats and isochronic tones for myself but I doubt for low frequencies states (Theta and Delta) which one is better? Because I searched a lot and saw that binaural beats are better for low frequencies and for high frequencies (Beta Gamma Lambda….) isochronic tones are more effective. Also, for Alpha states some said isochronic and other said binaural.
I have had your Equisync CD’s for a little more than 2 years. Some recent stresses prompted me to start listening to them again. Wow……these cd’s are no joke. I have been playing them consistently for the past 2 weeks and they are a tremendous help. I have to ask about the Equisync III cds. Can this elicit a detox reaction? I played it in its entirety one night and the next morning I felt like I was having a healing crisis. I am not complaining 🙂 I believe these particular cds allows tremendous amounts of healing light to enter the body through the higher chakras.
In the past few issues of the Advocate Voice Newsletter and the Fibromyalgia & Chronic Pain LIFE magazine, we have offered ideas about  several forms of cognitive behavior and mindfulness information.  In the chronic pain community these techniques combined with other therapies, including medications and alternative modalities, can help people sleep, function, relieve stress from pain and improve their quality of life.  This month’s app, Brain Wave, 30 Binaural Programs, is another tool to help introduce the idea of using your mind to help control pain and relieve stress.

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.

I have seen 1.5Hz being linked to HGH, but also 4 or 5 other frequencies as well, so it’s difficult to know what may work if any. I haven’t seen any research relating to HGH and brainwave entrainment. It’s widely believed that 40Hz is the limit for achieving a brainwave entrainment effect, which is also where many believe the gamma frequency range begins. Once you get over 40Hz into gamma your brainwave activity isn’t likely to stay in sync with it. So from a brainwave entrainment perspective, I recommend high beta frequencies for increasing energy during workouts.

Not only do certain brain wave rhythms get strengthened as a result of entrainment, but a dominant frequency band results in a different state of awareness. Those that have used a quality brainwave entrainment product can vouch for the fact that their perception is altered by their brain waves. Not only could this be due to brainwave changes, but it may be a result of increased interhemispheric communication.


The various mental states of the individual are thought to take place across a varied range of frequencies, or brainwaves. By encouraging the frequency following process, entrainment is able to create positive change in the brain, through matching carefully-selected frequencies of light and/or sound. The stimulus enables the individual to access a different state of consciousness, which can be useful for a number of benefits including relaxation, anxiety management, stress reduction and more.
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
hey thanks for wonderful ideas you posted. am kinda new to this whole idea and i was wondering if you could tell me with what types of audio tracks should i begin with. or if you could suggest some trusted and effective you tube videos, i would appreciate it. guys i will post my experiences when i have tried this thing. Thank you very much for your help Maya.
I'll give you a clue... How do you feel about money? Do you think you'll be rich, or do you worry about bills? Or... what do you think of yourself? Are you worthy of an awesome relationship, or will you just settle for the first person who comes along? Do you have your dream job or do you just do what you can to get by? Do you live life on your terms, or struggle desperately not to be noticed?
Theta brainwaves in the frequency range of 6 to 9 hertz are known as thalpha waves because of their proximity to alpha waves. They are seen during states of high suggestibility, during hypnosis, and during paranormal experience and are also connected to an increase in human growth hormone (HGH) levels and higher blood flow to the brain. Theta brainwaves sit between the realms of the subconscious and conscious mind, making them an especially useful brainwave state for developing creative thinking, working through emotional problems, and integrating subconscious and conscious experience. 
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.

Miscellaneous reports have also been made about the advantages of brainwave entrainment with the reviews of numerous users stating that the it can assist in increasing sex drive. Research shows that relaxation, meditation, and good self esteem ensures normal body functions. Furthermore, the brainwave entertainment allows your body to flow in rhythm with the beats therefore if your brain accepts and blends with certain frequencies, this could account for the enhanced sex drive.
That is very interesting to hear. I have also been an avid user of Holosync for long periods of my life. Were you progressing through the levels? I do know that Holosync in particular is designed for each level to push the brain to grow a “tolerance” to its effects. Once this happens the brain and nervous system has reached a new level of resiliency and is ready for the next level of the program, where the carrier frequencies are lower and more profound effects begin again. Was this the case for you? If Holosync was not your bag, you may also consider trying out some of the newer brainwave entrainment products with isochronic tones and monaural beats (holosync only uses binaural beats) as many have reported that they work better for them.
  There’s an added bonus feature you get with the Brain Evolution System™: scientific studies indicate that brainwave entrainment can not only enhance normal thinking to higher levels, but can also act as a “mood enhancer” to alleviate depression, chronic fatigue, and related conditions – as well as the physical symptoms brought on my too much stress.
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.

My personal experience of this was that it could get very harrowing; at times, I would literally be gritting my teeth and contracting my ribs while I was in meditation, because it was pushing me so hard. I began to ask, “Is it necessary to push this hard in such a static way and create overwhelm over such prolonged periods in order to propel spiritual evolution?”
* Headphones/Earbuds are Required for Binaural Tones to be Effective as the Left Ear and Right Ear Audio must be isolated for the Brain to perceive the inaudible low-frequency difference between the two sides. ** Changes to Orientation Support: With the upcoming arrival of several new devices with new screen-sizes and aspect ratios, iOS 8 required a re-write of our iPhone and iPad UI to support these devices, and as part of that, we have returned the app to a Portrait-only view for now. Once we know what these future screen dimensions and Aspect Ratios are, and have time to work with the real devices, we can implement a new Landscape UI for the iPad.
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.

So, I tried those frequencies. And after listening to the 1st one (High Beta to Gamma, Isochronic tones: 18HZ ramped up to 40HZ within 20 minutes) – I immediately stood up and started organizing! (Something that I kept forgetting to do!) Overall, I’ve found that isochronic tones & monaural beats are more immediately effective than binaural beats, though they are still good.
