What is a tympanometer also known as?

A tympanometer is commonly referred to as an impedance bridge. This device is used in audiology to measure the compliance of the tympanic membrane (eardrum) and the middle ear system. When a tympanogram is created, it provides essential information about the pressure and mobility of the eardrum, which helps in diagnosing various middle ear conditions, such as fluid in the ear or Eustachian tube dysfunction.

The term "impedance bridge" is derived from the device's ability to measure the impedance of the middle ear. Impedance refers to how much sound energy is blocked by the system, and understanding this impedance is crucial for audiologists in their assessments. The results allow clinicians to determine if the eardrum is functioning correctly and whether the middle ear pressure is within a normal range.

While other terms like "hearing aid test bridge," "acoustic bridge," or "auditory threshold meter" might relate to hearing assessments or different types of audiological equipment, they do not accurately describe the specific function or purpose of a tympanometer. Each of these alternatives serves different diagnostic purposes and does not encapsulate the primary role of measuring tympanic membrane mobility and middle ear impedance.
