subject: Binaural Beats! How Does it Work? [print this page] For example, if a pure 1000Hz tone is played on the left side and a 1500Hz tone is played on the right side, what your brain creates for the center channel is a 500Hz tone, 1500Hz - 1000Hz = 500Hz. This is well within the human auditory range, so it has no effect.
Now, if a 500Hz tone is played along with a 504Hz tone, the result is a 4Hz tone, well below our auditory range. This 4Hz tone is perceived as a 4 beat per second beat in your mind, and would correlate with the the Delta Brainwaves resulting in a powerful and proven altered state of being!
