The auricle, sometimes called the pinna, is the part of your ear that everybody sees. It includes your earlobes, where many people like to wear ear jewelry. Most of the auricle is made of cartilage, which is a soft type of bone.
The auricle works like a big funnel that collects sound and focuses sound towards your inner ear. Auricles can look different from person to person, but unless the unusual formation affects hearing, medical intervention is not required.
The outer ear consists of an outwardly visible part – the part you wear earrings on or cover with earmuffs. But there is also part of the outer ear that you can’t see with the naked eye, including your eardrum.
