Binaural Beats promote full brain synchronization and need headphones

Isochronic Tones are distinctly more powerful and do not need headphones

Some Basic History

Brainwave entrainment or “brainwave synchronization,” 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 visual, as with a dreamachine, a combination of the two with a mind machine, or even electromagnetic radiation.

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, Oster’s 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.

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 500 Hz in the example above), is also said by some to affect the quality of the transformative experience.[citation needed] Note that 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.[citation needed] 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.

Binaural beats were first discovered in 1839 by H. Dove, a German experimenter. At that time, binaural beats were considered to be a special case of monaural beats. Binaural beats are not the same as monaural beats. Binaural beats are perceived by presenting two different tones at slightly different pitches (or frequencies) separately into each ear. This effect is produced in the brain, not in the ears as with monaural beats. It is produced by the neural output from the ears and created within the olivary body within the brain, in its attempt to “locate” the direction of the sound based on phase.

Only monaural beats are the result of the arithmetic (vector) sum of the waveforms of the two tones as they add or subtract from one another, becoming louder and quieter and louder again.

Monaural and binaural beats are rarely encountered in nature, but in man-made objects, monaural beats occur frequently. For example, two large engines running at slightly different speeds will send “surges” of vibrations through the deck of a ship or jet plane. The lower pitched tone is called the carrier and the upper tone is called the offset.

Monaural beats occur in the open air and external to the ears. For example, when two guitar strings of slightly different frequencies are plucked simultaneously, monaural beats strike the ear as beats and therefore excite the thalamus, an action crucial for entrainment.Binaural beats played through loudspeakers become monaural beats.Binaural tones require headphones to be effective

To hear monaural beats, both tones must be of the same amplitude. However binaural beats can be heard when the tones have different amplitudes. They can even be heard if one of the tones is below the hearing threshold. Noise reduces the perceived volume of monaural beats whereas noise actually increases the loudness of binaural beats.

“Isochronic tones are evenly spaced tones which turn on and off quickly.”Unlike binaural and monaural beats, isochronic tones do not rely on the combination of two tones – the “beat” is created manually by turning a tone on and off. Widely regarded as the most effective tone-based method, isochronic beats produce very strong cortical responses in the brain. Many people who do not respond well to binaural beats often respond very well to isochronic tones. Isochronic tones are most effective using headphones.
