Immittance Testing

When testing middle ear function in infants and young children, audiologists typically rely on either tympanometry or acoustic reflex testing.

  • Tympanometry

    is a test of the middle ear used to detect fluid, wax buildup, eardrum perforations and tumors. It measures movement of the eardrum in response to air pressure; the results are recorded on a chart called a tympanogram.

  • The acoustic reflex test

    measures involuntary muscle contractions of the middle ear, and is used to determine the location of your hearing problem (the ossicles, cochlea, auditory nerve, etc.) as well as the type of hearing loss.
