Insomnia: Perhaps one of the most promising uses of brainwave entrainment technology is for those struggling with insomnia. While the technology is unlikely to provide a “cure” it may help those who have a high level of arousal or are “keyed-up” – reduce their level of internal arousal and sleep. Specifically insomnia that is induced by excess stress (e.g. beta activity) would likely benefit from slower wave stimulation (e.g. alpha activity) to aid the brain in transitioning into sleep.
Beta is the most common brain wave pattern: Beta brainwaves are produced when we are wide awake, alert, active and engaged in mental activity, usually involving more the rational, reality-oriented left hemisphere of our brain. When beta wave activity becomes very intense, our brain hemispheres become less synchronised. Beta state is required to function properly in your everyday life.
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.
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.
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.
Brainwaves are the collective electrical signal of millions of neurons working together in a living brain, producing our sense of alertness – or lack thereof - and producing our experience of reality. As brainwaves change, so does our perception of the world and our inner perception of ourselves. By learning to control our brainwaves, we can achieve specific, desirable mental states, such as feeling more relaxed, less anxious, more creative, more focused, or sleepier.

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.
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.
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.
Hi Julie! You’re very welcome for the info. In answer to your question, I think some are probably good, and some not so good. There are many people putting brainwave entrainment out there these days and it is not so easy to figure out which ones are and aren’t of reliable quality without investing time and doing some research. I would say (in general) that paid products are probably better quality than free ones, but I couldn’t guarantee this is a golden rule. My best advice is to just do your research before spending too much time listening to the freebies.
I just had to let you folks know how impressed I am with your Equisync CD’s, (Equisync I, Equisync II, & Equisync III). I just received the last two yesterday. I tried them both with amazing results. Especially the final CD, Equisync III. It creates a tone that is like a plane of sound that exists between the eyes all the way through your brain to the back of your head in the center. It is a tone, that if concentrated on purely, is the most amazing thing I have ever felt. I firmly believe it is some kind of door the the other side. It is like walking into a Lucid Dream. I am amazed many do not or know not about your technology and it’s wealth and value in understanding the self as well as our place in the Cosmos. I have recommended your product to others and will continue to do so. It is the first product, that has literally blown me away, and without the usual hype of products, such as these. It is it’s pureness, and it’s simplicity, that enables one to help oneself and others in this life. Using the CDs, at least initially, as almost entirely eradicated the intense pain I have felt for years. I have many forms of arthritis, all of which are degenerative, and incredibly intense. I have been able to work in my garden almost all day, without the usual restriction of pain and fatigue. I truly applaud you folks, you are definitely a Godsend….
The Frequency following response (FFR), also referred to as Frequency Following Potential (FFP), is a specific response to hearing sound and music, by which neural oscillations adjust their frequency to match the rhythm of auditory stimuli. The use of sound with intent to influence cortical brainwave frequency is called auditory driving, by which frequency of neural oscillation is 'driven' to entrain with that of the rhythm of a sound source.
