Definition
耳鼓 is a formal anatomical term for the eardrum (tympanic membrane), the thin membrane in the middle ear that vibrates in response to sound. It's used in medical or technical contexts — you're more likely to encounter it in a doctor's office or a biology textbook than in daily conversation. The everyday word for 'eardrum' is 耳膜 (ěr mó), which is more common in casual speech.
