# Journey of Sound to the Brain

This animated video illustrates how sounds travel to the inner ear, and then to the brain, where they are interpreted and understood. The cochlea in the inner ear is a spiral-shaped organ that contains hair cells, which sense sound vibrations. Hair cells convert sound vibrations into chemical signals that the auditory nerve can understand.
