A
Lens
B
Papillae
C
Drum
D
Pinnia
Explanation: 

Detailed explanation-1: -Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Detailed explanation-2: -Causes of ear vibration The causes of a vibrating ear including exposure to excessive loud noises, infections and other diseases. Exposure to frequently loud noises can damage the auditory system and lead to hearing loss, distortion in the perception of sounds and the perception of nonexistent sounds.

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: -The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles. The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).
