The visible part of your ear is called the pinna or auricle. This external structure is crucial for capturing sound waves and directing them into the ear canal. The pinna is made of soft cartilage and is shaped in a way that enhances its ability to funnel sound from various directions. It also plays a role in helping to determine the direction of sounds, which is essential for spatial awareness. While the pinna is just the exterior part of the ear, it works in conjunction with the middle and inner ear components to facilitate hearing.
