Impedance Audiometry (IA)

Assesses the status of the middle ear system.

Appropriate for individuals from 4 months through adulthood.

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.

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).

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