Middle ear
The eardrum forms the boundary between the outer ear and the middle ear. The ossicles – the malleus, incus, and stapes – transmit the vibration of the eardrum to the inner ear via the oval window. The middle ear is filled with air.

ear
The ear is not only the organ of hearing, but also of balance. A distinction is made between the outer ear with the auricle and external auditory canal, the middle ear with the eardrum and ossicles, and the actual hearing and balance organ, the inner ear with the cochlea and semicircular canals.

Ear drum
A thin membrane at the end of the ear canal that vibrates when sound waves hit it. The eardrum forms the transition from the outer ear to the middle ear. It is approximately 0.1 mm thick and has a maximum diameter of 10 mm. Contrary to what its name suggests, it is funnel-shaped.

Round window
The round window is a membrane-covered opening in the cochlea on the middle ear side. It is connected to the scala tympani and enables the necessary pressure equalization in the inner ear when sound is transmitted through the oval window.
