This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Despite this diminutive size and mass, the tympanic membrane is extremely tough and flexible, and difficult to damage beyond repair.

The tympanic membrane’s function is to assist in human hearing. , In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. Crossing the middle ear chamber there is an ossicle called the columella that is connected to the tympanum, and another ossicle, the operculum, that connects this to the oval membrane.
