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
Kelly Howell brings 30 year's experience to her expertise. She has been cited by the Mayo Clinic as "renown for her pioneering work in healing and mind expansion (and) visionary recording techniques." She has collaborated with neuroscientists and biofeedback therapists to invent a sophisticated sound recording technique that makes Brain Sync programs more effective. The result is the most elegant and effective brainwave synchronization audio programs available in the world today. You'll feel the effects from the very first time you listen. With regular use, you'll establish new healthy patterns that last. Brain Sync programs use window frequencies – extremely precise frequencies that fit through narrow biological windows to impact the body at the cellular level. The choice of frequencies selected for each program is based on biofeedback research. Programs are designed to help you self-generate optimized brain states exhibited by remarkable men and women.
The Brain Wave app uses advanced sequences of binaural tones that are combined with configurable ambient nature sounds and atmospheric music (or a person’s iTunes Music) to stimulate specific brainwave patterns. It includes powerful binaural sequences for sleep, focus, energy, positive mood, confidence, anxiety, stress relief, relaxation, yoga, memory, motivation, headache, concentration and meditation and more.
There are also ways of directing the entrainment pattern to further stimulate the brain in a desired way. Not all audios stay at the same frequency the whole time. Some will increase and decrease for a desired effect. Some will blend different beats at certain time to exercise the brain in a specific way. It is things like this that separate a good audio from a mediocre audio, and the difference between the two is undeniable when compared.
-Frequency of the Tone Itself that Makes the Beat (Carrier Frequency): The first frequency was the rate of the beat pulsing on and off. This frequency is the sound frequency of the actual tone that comprises the beat. This frequency also has an effect on the way the technology affects your brain and consciousness. For example, too low of a carrier frequency for a binaural beat can be too much for a beginner’s brain to handle at first, and too high of a carrier frequency can be not enough for an experienced meditator’s brain to make big changes.
Chronic fatigue: Subjective improvements in energy level may be reported by those who increase stimulatory beta and gamma waves. Fast waves tend to be associated with higher levels of arousal. Low arousal is associated with chronic fatigue and may be exacerbated by slow brain waves (e.g. theta and delta). As of now there aren’t any studies that have analyzed various protocols for their effect on a person’s energy or arousal.
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.
All brainwave frequencies are useful and beneficial at certain times – there is no brainwave that is intrinsically better than another. However, by deliberately choosing to attain a particular brainwave state, a corresponding mental state can be brought about at the same time. For example, a working person who has been in an overly alert beta brainwave pattern for many hours can quickly shift their mind and body into a relaxed state by listening to a few minutes of brainwave entrainment music for inducing alpha or theta brainwaves.
When the brain is stimulated with pulsed sounds (neuro-electrical activity via the nerves originating from the ears), the overall activity of the brain will respond to and align with these pulses. By selecting the desired rate, the brain — via the frequency following response (entrainment) — can be naturally induced towards the selected brainwave state.
The functional role of neural oscillations is still not fully understood; however they have been shown to correlate with emotional responses, motor control, and a number of cognitive functions including information transfer, perception, and memory. Specifically, neural oscillations, in particular theta activity, are extensively linked to memory function, and coupling between theta and gamma activity is considered to be vital for memory functions, including episodic memory.
