What does tympan mean?
Tympan is an uncommon noun for the eardrum, the membrane at the inner end of the external ear canal that vibrates in response to sound. In anatomical and clinical contexts, it names the tympanic membrane, separating the outer and middle ear. The word is precise but unusual in ordinary conversation, where eardrum is much more familiar. Tympan also has an older or specialized musical sense referring to a drum or drumhead, reflecting the membrane's resemblance to the stretched skin of an instrument. The term is related in English to tympanum and to the plural timpani, while tympanic forms the familiar adjective in tympanic membrane. Etymologically, the word derives from Greek tympanon, meaning drum, via Latin and French. Its history makes it a useful example of how a word associated first with percussion can come to designate the small, sound-sensitive membrane that resembles a drumhead. Today it is most likely to be encountered in medical writing, specialist descriptions, or historical discussion of musical instruments.

"The doctor explained that fluid behind the tympan was restricting the patient's hearing."
"A middle-ear infection caused fluid to press against the tympan."
"The surgeon's notes referred to a small perforation in the left tympan."
The regular plural is uncommon because eardrums and tympanic membranes are more natural in general usage.
"The clinician noted that both tympans appeared intact."
The eardrum earned its formal name by looking—and working—like a tiny drum: Greek tympanon and Latin tympanum both meant "drum."
