Quizplus · Accepted Answer

The pinnae are the external ear structures that help collect and funnel sound waves into the ear canal. By moving his pinnae, Clifford can adjust the directionality of sound and thus more effectively localize the source of a sound, even if it is very faint. The basilar membrane, stapes, and organs of Corti are all internal structures of the ear that are involved in detecting and processing sound, but they do not help with sound localization in the same way that the pinnae do.
