The sound of birds chirping in the morning, a babbling brook or crashing waves on the beach, or warm conversation with the ones you love. The experience of all these things requires the ability to hear. Arguably the most important sense for human communication, it is also the most commonly impaired of our senses. In this module, you will learn how the human ear is artfully designed to enhance our ability to hear the human voice. You will follow sound waves as they travel from the external world, to the eardrum, through the bones of the middle ear, and to the cochlea that transduces sound information into neural impulses.
