Tympanic Membrane Pictures, Function & Anatomy | Body Maps The tympanic membrane is a relatively thin connective tissue structure, and is susceptible to perforation (usually by trauma or infection). Function of the eardrum. This causes an increase in pressure within the middle ear, and eventually the eardrum can rupture. However, in some cases the magnitude of HL exceeds that attributable by the TM perforation alone. Since the tympanic cavity is a cavity system, this anatomical structure is permanently filled with air. [1] When the tympanic membrane perforates, it may no longer create the vibrational patterns, leading to hearing loss in some instances. Its main function is to act as a resonator. Discover the way this membrane functions like a musical 'drum', and. The main function of the tympanic membrane is to transfer sound waves from the air from outside, which reach the membrane through the external acoustic meatus, to the auditory ossicles in the middle ear, which then conduct the vibrations to the oval window transferring them to the fluid and membranes of the cochlea of the inner ear.
