Measurement of the movement of the tympanic membrane and pressure in the middle ear is:

A) tuning fork test.
B) tympanometry.
C) otoscopy.
D) Rinne test.

Tympanometry

A diagnostic test that measures the movement of the eardrum in response to changes in air pressure, used to detect fluid in the middle ear or Eustachian tube dysfunction.

Tympanic Membrane

Also known as the eardrum, it is a thin layer that separates the outer ear from the middle ear and vibrates in response to sound waves.

Middle Ear

The air-filled space located between the eardrum and inner ear containing the auditory ossicles.
