Brain entrainment technologies harness your mind powers by putting the natural phenomenon of brainwave entrainment to work for you. They help you achieve your wellness and life goals by optimizing brain wave patterns that facilitate learning and taking actions with a relaxed focus.
You experience shifts in your brain's electrical pulses throughout the day as you experience different emotions and engage in various activities. Waking, sleeping, studying, trancing as you drive, being in animated conversation all change your brain's electrical activity. It also responds to stimuli from the environment. As you listen to the tick-tock of the clock or rhythmic, repeated drumbeats, you experienced entrainment and its accompanying shift in consciousness.
Hypnosis and meditation are two long-time methods of affecting brainwave states to change your thoughts and help you relax. In recent years, medical professionals, therapists, and self-help educators have taken advantage of modern technology to create new methods of balancing and changing brainwaves for specific purposes. Research shows that they facilitate relaxation, the release of negative thinking patterns, faster recovering, and better academic functions. This technology is sometimes combined with guided meditations and hypnosis to get to deeper brain states quickly.
With regular use, you can experience the benefits of deep meditation in a fraction of the time it would take if you were practicing on your own. Experienced meditators practice for many years before being able to reach the deep, slow wave frequencies that binaural beats naturally induce.
This Brain Evolution System graphic illustrates the change in brain waves after using the audio for only 15 minutes. Notice how much calmer and relaxed the waves are in such a short time.
Brainwave entrainment programs work because the electric cycles of the brain match up, or entrain, with consistent repeating audible beats or visible flashes of light much the same way pendulums synchronize in a clock shop.
This technology works in one of three ways: rhythmic entrainment, binaural beats, and monaural beats.
Isochronic, or rhythmic entrainment, uses a single manually spaced tone that turns on and off rapidly in a specific pattern. This newer form of brain entrainment does not require headphones and has stronger impact on the brain than binaural beats. Rhythmic entrainment is used in music therapy to help people tune into their own rhythm and the rhythms of the world around them. It assists with motor planning, social awareness, and language development. The beat of the music helps the brain make connections. If you have ever tapped to the beat of a drum or danced in unison with others to a specific song, you have experienced rhythmic entrainment.
Binaural beats cause your brain waves to cycle at a desired frequency by playing a different sound frequency into each ear through a set of stereo headphones. You normally don't hear these beats, just the music or white noise that overlays them. Binaural beats has been shown to increase IQ, sharpen focus and thinking skills, improve problem solving and creativity, and improve energy and motivation.
The concept behind this technology is rather brilliant. Yes, your brain will synchronize to a regular beat, whether audible or visual, if you perceive it. The problem is, sounds below 20 Hz are inaudible to most people. To generate more alpha waves and the relaxed focus that comes with it, you need to listen to 14Hz or lower. The healing, mildly hypnotic theta state tops out at 8 Hz, far below human hearing range.
Entraining your brain with binaural beats gets around that difficulty.
As this Brain EV graphic illustrates, a frequency of 400 Hz may be played into the left ear while the right side receives 410 Hz.
Your brain processes both sound frequencies, but only the difference of 10 Hz is heard.
Even though your brain perceives this 10 Hz sound, it is not an actual sound at all. It is an electrical signal created as your brain processes each tone from the left and right ear separately.
Your brainwaves synchronize, or entrain, to the phantom 10 Hz alpha frequency as the signal is continuously processed over time.
As both sides of the brain work in unison, the high functioning brain state of hemispheric synchronization or whole brain sync can occur.
By varying the difference between the two frequencies being channeled through the headphones, the program can induce your brainwaves to slow to alpha, theta and possibly into delta waves.
Some programs, such as the Insight program include a progression through these three brainwave frequencies. Other programs, like Holosync and the Brain Evolution System, include several audios that you progress through over a specified period of time. Eventually, you can induce a desired brain frequency at will, much like experienced meditators do.
Monaural beats work in much the same way except they use a single speaker to bring two frequencies together to create an audible pulse.
Brain EV is a six level brainwave meditation program that can help you enjoy less stress,better mood and more focus in 30 minutes a day.
The Brain Evolution System uses a unique combination of rhythmic isochronic tones, binaural beats and temporal brainwave entrainment that stretches and compresses sound to facilitate the ebb and flow of brainwave rates.
This brain entrainment process matches the dynamic shifting quality of natural processing just like regular brainwaves do. It helps the brain accurately follow the intended frequencies of the entrainment program for optimum results.
Not ready or interested in a long-term program? Give Brain Salon a try. This collection of six-30 minute brainwave entrainment recordings is designed to help you relax, sleep, and enjoy more energy, creativity and focus right away. No headphones required.
Note: Consult a physician before using brain entrainment technology if you are pregnant, are wearing a pacemaker, are prone to seizures or photosensitivity, and if you are under the influence of medication or drugs.
