listen using headphones only - it changes
Binaural Harmonics - The sensation of auditory binaural beats occurs when two coherent sounds of nearly similar frequencies are presented to each ear with headphones. If the left ear is presented with a steady tone of 200Hz and the right ear a steady tone of 210Hz, these two tones combine in the brain producing a sensation of a third sound called the binaural beat. This 10Hz beat signal is formed entirely by the brain. Binaural beats originate in the brainstem's superior olivary nucleus, the site of contra lateral integration of auditory input. Monaural beats produced with two tones of equal intensity sound clean and pure. Binaural beats initially have a slight warbling sound as your brain adjusts this will disappear. This is a very brief explanation as it gets cut off by emusic but hopefully it helps you to see that if you listen it changes from "static" and benefits the brain.
