Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Sound transfers into the ear canal and causes the eardrum to move. The eardrum will vibrate with vibrates with the different sounds. These sound vibrations make their way through the ossicles to the cochlea. Sound vibrations make the fluid in the cochlea travel like ocean waves.
