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: -The pinna catches sound waves and channels them down the external auditory canal, where they hit the tympanic membrane and make it vibrate. Those vibrations cause the three ossicles to move.
Detailed explanation-3: -Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate. The eardrum is connected to the malleus, one of three small bones of the middle ear. Also called the hammer, it transmits sound vibrations to the incus, which passes them to the stapes.
Detailed explanation-4: -External auditory canal or tube. This is the tube that connects the outer ear to the inside or middle ear.
