Which component of the outer ear plays a role in collecting sound?

Explanation:
Collecting sound is handled by the outer ear's pinna. The pinna is the visible part of the ear, with its folds and curves designed to capture sound waves from the environment and funnel them into the ear canal toward the eardrum. Its shape also helps with localizing where sounds come from and even boosts certain frequencies, which aids speech perception. The eardrum (the tympanic membrane) is the boundary between the outer and middle ear and primarily transmits vibrations inward rather than acting as a collector. The oval window and round window are openings into the inner ear, involved in transferring those vibrations into the fluid-filled cochlea, not in collecting sound.
