+of sound in the brain is actually quite slow. Yes \, the ear can perceive
+changes on the order of 0.05ms (20 \, 000Hz) \, but your brain is made
+consciously aware of these changes at a much slower rate. You can hear
+an example of this using a oscillating frequency. A slow change in
+the frequency of a tone is perceived as vibrato \, you can consciously
+hear the wavering pitch. As that change in frequency becomes faster
+\, you can no longer consciously hear the wavering pitch. Instead you
+perceive a steady tone.;
