The outer ear is the visible part of the ear that collects sound waves from the environment. It consists of two main parts: the pinna, which is the curved structure that protrudes from the head, and the ear canal, a tube that leads to the inner parts of the ear. The outer ear helps direct sound waves toward the eardrum. The outer ear plays a crucial role in hearing by amplifying and funneling sounds. It also helps in determining the direction of sounds, allowing us to locate where they are coming from. Proper care of the outer ear is important for maintaining good hearing health.
