What is the primary function of the outer ear?

The primary function of the outer ear is to protect and collect sound waves. The outer ear consists of the pinna (the visible part of the ear) and the ear canal, which work together to gather sound waves from the environment. The shape of the pinna helps funnel these sound waves into the ear canal, where they ultimately travel to the eardrum. This collection of sound is crucial for hearing, as it ensures that sound waves are directed efficiently toward the inner workings of the ear where sound processing begins. While the other functions mentioned are indeed important steps in the overall process of hearing, the primary role of the outer ear specifically revolves around its ability to capture and protect sound waves before they move deeper into the auditory system.
