Impedance Audiometry (IA)

Purpose:
Assesses the status of the middle ear system.

Age:
Appropriate for individuals from 4 months through adulthood.

Procedure:
A probe tone is introduced into the ear. The amount of sound reflected by the tympanic membrane is measured by a probe in the ear canal as the pressure in the ear canal is varied.

Results:
To provide information about the status of the tympanic membrane and middle ear system. (i.e., middle ear pathology/effusion, negative pressure possibly indicating Eustachian tube dysfunction).

Limitations:
Specialized equipment is required for accurate assessment of infants under four months of age.
