Binaural Beats

Binaural beats are used as a method of brainwave entrainment to induce a desired state of awareness.

A binaural beat is created by using differing hertz frequencies. The difference is dependent on the desired state of awareness.

Delta waves = 0hz - 4hz (deep sleep)
Theta = 4hz - 8hz (deep meditation, REM sleep, HI)
Alpha = 8hz - 13hz (relaxation, meditation, awake)
Beta = 13hz - 30hz (awake)
Gamma = 30hz - 60hz (heightened awareness)

Binaural beats must be listened to with a good pair of stereo headphones, as one frequency gets played to the left ear, and another frequency is played to the right ear.
