What is "concha"?

The concha, also known as the auricular concha or ear concha, is a curved and hollow structure located within the external ear. It is formed by the concha bowl, a concave depression that helps collect and funnel sound waves into the ear canal. The concha plays a crucial role in directing sound vibrations toward the middle and inner ear, contributing to our sense of hearing and spatial awareness. Additionally, it aids in the protection and maintenance of the ear canal by preventing the entry of foreign objects and debris.
