What does timpanum mean?
Timpanum is chiefly a technical term for the eardrum, the delicate membrane at the inner end of the outer ear canal that vibrates when sound reaches it. In anatomy, it may refer specifically to the tympanic membrane and is closely associated with the middle ear and the bones known as the ossicles. General readers will usually encounter the clearer and more familiar terms eardrum or tympanic membrane, but timpanum remains standard in medical writing. The word also has a specialist musical sense, denoting a kettledrum, although modern English usually calls the orchestral instrument timpani. Its vocabulary history connects hearing and percussion: Latin timpanum meant “drum,” and the anatomical meaning developed through the comparison between that vibrating membrane and a drum. Timpanum is therefore useful not only as a precise anatomical term but also as a word linking the mechanics of hearing with the history of instruments.

"The timpanum was tuned to a low D for the finale."
Timpana is the standard plural in specialized anatomical and musical contexts.
"The examination showed reduced movement in both timpana."
The word meaning “eardrum” also literally means “drum,” an apt echo of the role sound plays in hearing.

Where does timpanum come from?
English borrowed timpanum from Latin during the Middle English period. Latin timpanum, meaning “drum,” came from Greek tympanon and belongs to an etymological family that also includes words such as tympanic and timpanist. The anatomical sense developed through the longstanding comparison of the vibrating eardrum to a drum.
How timpanum is actually used
In medicine, timpanum is a technical term, while eardrum and tympanic membrane are more common in general usage. Its musical sense is uncommon; timpani or kettledrum is normally preferred when discussing the instrument.
