The Pinna is the external portion of the ear. The funnel-like shape functions to collect and amplify sound naturally, optimizing it as it travels further into the auditory system.
The human body is amazing. I chose to study Hearing Speech Language Sciences and went on to get my Doctorate in Audiology because I believe that our ability to communicate is what makes us innately human. Basic communication happens because we need something. Babies cry when they need food, shelter or clothes. They will later learn to express these needs through other forms like speech, sign language, etc. What I find fascinating is what happens on the other side of communication; the listening and understanding portion. This side of communication helps to creates bonds and foster compassion. It connects people to people and connects people to experiences.
