Brain Tuners are based on brain wave studies using electroencephalography (EEG) technology to map different states of consciousness known as Delta, Theta, Alpha, and Beta. Delta is associated with deep sleep. Theta is associated with meditation and dream states. Alpha is associated with relaxed awareness, creativity, and heightened learning. Beta is associated with high alertness and focus.
When the Brain Tuners are simultaneously sounded – one in the left ear and the other in the right ear – the two hemispheres of the brain function together to integrate the two sounds, creating a third, different tone called a binaural beat. When the Fundamental Brain Tuner tuning fork is sounded with a Delta, Theta, Alpha, or Beta tuning fork, the difference between the two tuning forks creates a binaural beat which is heard as a pulsation. The binaural beat gently signals the brain to shift into a different state of consciousness.
