How does BWE work

Explaining the basics behind brainwave entrainment

   The human brain was discovered to be influenced by a repeating stimuli like light, sound or EM fields. It literally follows the frequencies that it is subjected to, so long as certain conditions are adhered to.

   For example if the brain experiences a flashing light stimuli at 7 hz (cycles per second), then slowly it will begin to slow down or speed up to that frequency! In this case, 7 hz is found in the Theta range and so the brain would ultimately do what it would normally do in this range...dreaming sleep! This type of brainwave entrainment, using strobing lights, is commonly found in commercial mind machines (see our dedicated mind machine page for more info)

   An alternative to using light as a stimuli, is to use sound. Audio waves do go down to the ranges necessary, however, quite often would be out of our hearing range (approx 20Hz-20KHz) and difficult to produce without sub speaker units. And so, we can't just listen to these frequencies.
   Instead 2 methods are used to achieve brainwave entrainment for audio:

- Binaural Beats - By applying two slightly different tones (small difference in pitch or frequency), one in each ear, the brain inteprets the difference as a third tone or pitch. It actually then ignores the 2 individual tones and concentrates on this new third tone. It is the frequency or pitch of this tone that the brain starts to follow and so starts brainwave entrainment! This method is also used in some light and sound (mind) machines like the Proteus and the Sirius mind machines. They use binaural beats to double the effect of the light stimulation. You can see more on these two products later... Of course, this principle relies heavily on using two speakers or heaphones.

- Modulation - If you produce noise (a random toneless sound) and then fluctuate its pitch or volume at a frequency, this can cause the same effect as binaural beats with only a single speaker and there is no need for headphones! There is some debate as to which is more effective for brainwave entrainment. For the ultimate, it is suggested that both visual and audio stimuli are used for a more pronounced effect.
