Brainwave Entrainment Glossary
There is a longer explanation for brainwave entrainment here.
a) Brainwaves are the electrical impulses your brain creates all the time. This is what is being measured when an EEG reading is taken. The rate of the pulses varies depending on what you are doing or even what you are thinking or dreaming. For example when you are relaxed they generally pulse in the alpha range and when you are alert in the beta range.
b) Entrainment means follow and synchronize with. The entrainment in our audios means that your brainwaves begin to pulse in time with the beats and tones that it hears on the audios.
c) Putting this together brainwave entrainment means that the listener' s brainwaves will begin to pulse in time with the beat or tones embedded in the audio being played. The audio has specially constructed beats and tones which are set at the rate required for the condition that is being treated.
So for example if you are anxious the audio for anxiety treatment will be set to mimic the brainwave pulsation of calmness. The brainwaves begin to follow and synchronize so that soon they are pulsing at a "calmness" rate and the result is that the listener begins to calm down. Over time this has a long term beneficial effect on the persons anxiety levels.
Binaural beats are a form of brainwave entrainment using two separate sounds that combine to form one sound inside your brain. One benefit that is often mentioned is that in order for the brain to create a binaural beat, it must use both hemispheres of the brain (right and left), which is claimed to produce "hemispheric synchronization".
Because the sound delivered to each ear is different binaural beat audios must be listened to with headphones.
Binaural beats or binaural tones are artificially induced rhythms that the brain produces when exposed to two separate sounds one in the left and the other in the right ear. The beat that is created is the difference between the two frequencies. For example, if 300 Hz is played in one ear and 310 Hz in the other, then the binaural beat would have a frequency of 10 Hz.
Stereo headphones must be used to create this effect because a different sound must be played into each ear. The frequencies used must be below 1,000 hertz and the difference between the tones must be 30 Hz or less. If not the effect will not occur and the two sounds will be heard as two rather than one different beat.
Binaural beats are better known than other brainwave entrainment tones but they have been found to be less effective than isochronic tones. For this reason we do not use binaural beats alone.
Harmonic Box X
Harmonic Box X is a tone-based brainwave entrainment method described by James Mann in his book, Awakening Mind 1. It has become quite popular in recent years. The method is unique in that it incorporates both monaural and binaural beats, in a harmonic formation. Because it uses binaural beats it requires headphones.
Monaural beats are similar to binaural except that the brainwave entrainment sound is formed outside the brain. This means you do not need to wear headphones.
Isochronic beats do not rely on the interaction of two tones to form a beat. Instead, a beat is formed manually using audio modulations. They have been found to be very effective in inducing entrainment. In fact they are more effective than the better known binaural beats but some people think that they do not sound as relaxing. You do not require headphones to listen to isochronic beats.
