Most of our Royalty Free brainwave entrainment music uses an audio technology known as "binaural beats". These binaural beats are embedded in the music in order to bring about desirable changes in brainwave activity, thereby encouraging various states of relaxation, deep meditation or sleep. When played with headphones, you may be able to hear the binaural beats as a subtle pulsing sound beneath the music.
“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.”
With each pulsed tone, the brain produces an electrical response. The effects one experiences are the creations of the brains reaction to the “tones”, what neurologists call the “cortical evoked response” (the electrical response of the top most cortical layer of the brain). The brain is a mass of neurons, each taking part in storing, retrieving and transmitting electro-chemical impulses: information, colors, images, sounds, smells and tastes. Brainwave entrainment stimulates different areas of the brain allowing for the awakening and subsequent release of various levels of stored material. It also has an effect of  quietening the mind for clearer thought and process.

From a brainwave entrainment effectiveness perspective, it’s my understanding that the response from isochronic tones stimulation starts to diminish over 30Hz and that 40Hz is about the limit for using them. So from what I’ve read on the topic a 100Hz beat wouldn’t work, probably because it’s too fast for the brain to process and synchronise with it.

With regard to that, I would like to tell you a story about GMO. I recently explored a case study about GMO products, which explained how initial research showed no negative effects were caused by GMO products. A group of French scientists, however, decided to gather a research group and examine more closely  its effects by prolonging the study for up to four years. What they discovered was that although no initial side effects were seen in the tested animals, after the third year of the study, the ones that were fed with genetically-modified foods started developing tumors that affected more than 1/3 of their bodies.
The mechanism for this is that when your eyes or ears are exposed to a particular frequency of pulses or beats, the thalamus first distributes this information to the entire brain, including the visual and cerebral cortex where neural activity begins to synchronize to the incoming frequency, producing hemispheric synchronization and a balance of brainwave activity across the brain.
I was using Jeffrey Thompson brainwave cd material for several weeks and suddenly developed severe anxiety, headaches in the forehead and dizziness and confusion . I stopped but the symptoms are still with me a week later. Will these symptoms go away? This isn’t some bad kundalini awakens g it something is it ? Will I get better snd how long will it take to go away? Message me at or message me in FB at Nicholas Pierotti (the guy in the hat hugging his daughter ) Please let me know
a concise P.S. I was in a horrible car accident when I was 18 and had to learn to read and write and walk and talk all over again. It was long ago and I’m pretty well over it, but such an injury has lifetime repercussions. The neurological damage sustained causes my left arm to shake uncontrollably anytime I use it in a situation requiring precise coordination. From simply listening to the demo, the shake [though not disappearing completely in the last 2 months] has lessened dramatically. I had been wondering for years what kind of neurological exercises I could undergo to help it…
The reported PMS symptoms that improved included: affective lability, anxiety, appetite changes, bloating, breast tenderness, concentration difficulties, depression, fatigue, and irritability. Researchers noted that there was a clear “trend” toward a reduction in social withdrawal as a result of symptoms as well. A total of 49/50 women reported improvements.
Two people with ADHD for example could have completely different ADHD subtypes. One could have inattentiveness as the primary symptom as a result of high theta waves, and the other could have high beta-2 waves as feel hyperactive. While generalized entrainment protocols should be studied, it is important to consider that each person may respond differently to the protocols; each person has a unique neural footprint.
This thing blows my mind! The first time I used it I was like "No way!" As I kept using it I discovered that it is literally the only way I am able to fall asleep nights when my mind is so full of thoughts and my anxiety is running rampant! I hate the way sleep aids make me feel like I've been run over by a freight train. I recently switched from using "Deep Sleep" to "Dreamy Sleep" and had the craziest dreams! I normally can't remember my dreams and I was actually able to recall quite a bit of them. Unfortunately last night, I dreamt that I faked the death of my dog last year and I felt like it lasted the whole night so I think I'll be switching back to "Deep Sleep" :( Awesome product though. My *only* complaint is that I wish there were more ambiance options or the ability to use it with Pandora. You can use your own music but I don't have much personal music on my phone so I am limited to using the app's ambiance tracks and they get old after a while. Highly recommend!

In fact, there is more to answering this question than meets the eye. As someone who’s also been skeptical enough to do the research, I am more than happy to explore the issue in great depth. The important thing to address here is what have you been told that Brainwave Entrainment would do?  Depending on whose site you’ve landed on you may have been promised different things.  The promised benefits of this type of product are a long list, and more things are still being added to it.  You may have been told that brainwave entrainment would help you meditate deeper, and rocket launch your spiritual evolution from doing so.  You may have been told that it would help your brain release positive neuro chemicals and anti-aging hormones that would improve your health and help you feel more positive emotions, overcoming anxiety, and you also may have been told that listening to brainwave entrainment on a regular basis would help your brain evolve, building a higher threshold to mental and emotional input, growing neural pathways, and synchronising the two hemispheres of the brain.
