The science behind Binaural beats occurs in the brain. Binaural Beats are perfect for deep relaxing your body & soul, for yoga, massage or meditation. A different sound(tone) frequency is sent to the left and right ears. Upon hearing the two different frequencies (one in the left ear and one in the right), the brain interprets these two different frequencies as one consistent, rhythmic frequency, known as a Binaural beat(s). The resulting frequency that the brain interprets is the mathematical difference between the two frequencies of the left and right tones that were sent to the left and right ears. The brain then follows along at this frequency .
