Have you ever wondered how sound waves turn into the noises we hear every day? The National Institute on Deafness and Other Communication Disorders has answers.

In a two-and-a-half minute animated video, "Journey of Sound to the Brain," researchers show how sound travels from the ear to the brain, where it is interpreted and understood.

The video teaches about the deepest parts of the inner ear and shows how this process helps us communicate with the world around us.
