The phenomena of brainwave entrainment was first described in the scientific literature in 1973 by Gerald Oster in results published in an article in Scientific American entitled, “Auditory Beats in the Brain”. He showed that a specific brainwave could be induced when a person heard two separate, but closely related, sound frequencies, one in each ear. He discovered that when the frequencies heard by each ear differed by about 10 hertz, the brainwave pattern of the person hearing the sound would synchronize to the difference between the two frequencies. For example, if the person heard a 410 hertz sound in one ear and a 400 hertz sound in the other ear, their brainwaves would stabilize at the difference between the two, or 10 hertz. This technique is called binaural beats, and it is a fundamental principle of brainwave entrainment methods.
Joseph Kao, creator of Journey to the Center of the Self, a deep, 30-minute, guided transpersonal meditation, accompanied by music embedded with advanced brainwave entrainment technology and followed by 30 minutes of only the brainwave entrainment music, talks with iAwake’s CEO, John Dupuy, about all that went into the making of this meditation tool masterpiece.

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.
Lucid dreaming: A lucid dream is considered a dream that a person is aware of and often able to consciously manipulate. Many have alleged that using brainwave entrainment technology makes it easier to experience a lucid dream. Scientists have studied this phenomenon and noticed that beta frequencies within the range of 13 to 19 Hz tend to be generated to keep the person conscious. Additionally there is significant increased activity in the parietal lobes of the brain, which allows an individual to stay conscious.
Neural oscillations are rhythmic or repetitive electrochemical activity in the brain and central nervous system. Such oscillations can be characterized by their frequency, amplitude and phase. Neural tissue can generate oscillatory activity driven by mechanisms within individual neurons, as well as by interactions between them. They may also adjust frequency to synchronize with the periodic vibration of external acoustic or visual stimuli.
