The tympanic membrane, also known as the eardrum, is the landmark which connects the outer ear from the middle ear. It is made up of layers of thin membranes. When sound waves travel through the ear canal, they vibrate the tympanic membrane. These vibrations are then transferred to the ossicles. If the tympanic membrane is not vibrating normally for any reason, a conductive hearing loss will result.
