Binaural Beats

From the website: "The science behind binaural beats occurs naturally in the brain. A different sound (tone) frequency is sent to the left and right ears through headphones.Upon hearing the two different frequencies, the brain interprets one consistent, rhythmic frequency, known as a binaural beat(s). The resulting frequency, interpreted by the brain, is the mathematical difference between the two frequencies sent to the left and right ears. The brain then follows along at this frequency and produces brainwaves of the same frequency."
