Content of the sound: Binaural Beats for Brain Scanning, Alpha 9,5 Hz, 126,22 Hz Base Frequency Brainwave Entrainment is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep), usually attempted with the use of specialized software. It purportedly depends upon a frequency following response on the assumption that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus.[citation needed] Such a stimulus is often aural, as in the case of binaural or monaural beats and isochronic tones, or else photic (visual), as with a dreamachine, a combination of the two with a mind machine, or even electromagnetic radiation. Hemispheric Synchronization, a potential and generally desired result of brainwave entrainment, refers to a state when the brainwave pattern of the right and left hemispheres become alike. A person with similar activity in both hemispheres is alleged (typically by companies trying to sell a product) to be happier, more optimistic, more emotionally stable and less prone to mental illness. Increased levels of synchronization are found naturally in people who meditate regularly and people who are very content with their lives in general. While there have been many small-scale studies done (see below for some samples), there has not yet been a large-scale or long-term study of brainwave entrainment. Binaural beats deserve special mention because of the manner in which the desired frequencies are obtained. Brainwave entrainment may be achieved when audio signals are introduced to the brain causing a response directly related to the frequency of the signal introduced, called binaural beats. Two tones close in frequency generate a beat frequency at the difference of the frequencies, which is generally subsonic. For example, a 495 Hz tone and 505 Hz tone will produce a subsonic 10 Hz beat, roughly in the middle of the alpha range. The carrier frequency (e.g., the 505 Hz in the example above), is also said by some to affect the quality of the transformative experience. This effect is achieved without either ear hearing the pulse when headphones are used. Instead, the brain produces the pulse by combining the two tones. Each ear hears only a steady tone. Although some have claimed that these frequencies do provide help in treating certain medical conditions, there is not a wide acceptance by the medical community to adopt the practice of brainwave entrainment for emotional/mental disorders. A fixed, constant frequency of synchronization is less helpful than techniques such as classical neurofeedback or learning meditation, which naturally generate brainwave frequencies that differ from person to person and may vary from minute to minute. Enthusiasts of brainwave entrainment claim that it has been noted or used in one form or another for centuries (long before the invention of EEG equipment), from shamanistic societies use of drum beats to Ptolemy noting in 200 AD the effects of flickering sunlight generated by a spinning wheel. In the 1930s and 40s, with then-new EEG equipment and strobe lights, William Grey Walter performed some of the first scientific research on the subject. Later, in the 1960s and 70s, interest in altered states led some artists to become interested in the subject, most notably Brion Gysin who, along with a Cambridge math student, invented the Dreamachine. From the 1970s to date there have been numerous studies and various machines built that combine light and sound. These efforts were aided by continued development of micro-circuitry and other electronic breakthroughs which allowed for ever more sophisticated equipment. One of the more frequently noted scientific results claimed for brainwave entrainment was the discovery of binaural beats, published in Scientific American in 1973 by Gerald Oster. However, Osters research actually makes no mention of brainwaves. With the development of isochronic tones by Arturo Manns, combined with more sophisticated equipment, these discoveries led to many attempts to use claimed brainwave entrainment techniques in the treatment of numerous psychological and physiological conditions.
