Answer

Sound waves send vibrations through the membranes and fluids of the ear. Impulses along the cochlea create information that is then transmitted to your brain, where it is translated and understood to be your name. The most likely direction of the origin of the sound is also determined. Your brain then sends signals to the muscles and connective tissues in your neck, head, and back to cause you to turn your head in the direction of the sound.
