Mechanics of the Mammalian Cochlea Physiological Reviews Login to your account Institutional Login Sign In / Register The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane. … See more The vibrations from the eardrum set the ossicles into motion.
