Binaural beats (also known as brain entrainment) are created when two different tones are played to each individual ear. The brain detects the difference between these two tones and attempts to reconcile the difference. The effect is the perception of a third tone, which is called the binaural beat.
The binaural beat is simply the difference between the first two tones. So if I play a 100hz tone in one ear, and a 107.5hz tone in the other, then a binaural beat of 7.5hz is created. This tone is associated with the enhancement of creativity.
Research has shown that when introduced to a binaural beat, the brain begins to follow this beat. So if for example you play a 100hz tone in one ear and a 110hz tome in the other, a binaural beat of 10hz is produced. The brain then follows this beat and gets into a relaxed 10hz cycle. This can help guide a persons’ brain to the natural alpha state, which is between 7-13hz, and can produce a nice relaxed pre sleep state of mind.
The 10hz tone does not actually exist, but we hear one anyway.
Probably the best way to fully understand binaural beats is to experience them for yourself. Bellow is a free session for you to try for yourself. Make sure you wear headphones whenever you listen to binaural beats audios or else you will miss most of the binaural effect produced when listening to different sounds in each ear.
Try this free session for yourself…
