Which part of the ear is the external portion that collects sound waves?

Explanation:
The outer ear is the external portion that collects sound waves. It includes the visible pinna (the outer ear flap) and the external auditory canal. The pinna helps capture and direct sound toward the ear canal, and the canal channels those waves inward toward the eardrum. Behind the eardrum lie the middle ear structures that transfer vibrations to the inner ear, while the inner ear processes those vibrations into neural signals. The Eustachian tube connects to the throat to equalize pressure, not to collect sound. So, the part that first gathers and funnels sound is the outer ear.
