Middle Ear Testing

Middle ear testing or impedance testing is used to determine the overall health and function of the middle ear. This test evaluates the external ear canal volume, the mobility of the eardrum and integrity of the occicular chain (middle ear bones). These tests are essential in identifying perforations of the eardrum, abnormal pressure in the middle ear space, wax blockage in the ear canal, and possible conductive hearing loss.

During this exam, a probe is placed in the ear and air pressure is increased and decreased as a tone is emitted. A graph will be created to show the results of the test. This test helps us determine if hearing loss is conductive in nature.

Impedance testing is an important part of a complete audiometric evaluation. This test is vital in assessing the hearing of young children who often experience middle ear pathologies.


middle ear testing Your middle ear has another important job; it actually protects you from loud sounds! Tiny muscles in the middle ear contract when a loud sound occurs as a way of protecting your hearing. One set of muscles actually pulls the stirrup bones (stapes) away from the cochlea to reduce the transmission of loud sounds to your inner ear. Another set of muscles contract pulling the hammer bone (malleus) away from the eardrum. This reflex reduces the transmission of energy to the cochlea or reduces the volume of sound transmitted through the bones of your middle ears, thus helping prevent inner ear damage.

Your ears begin protecting your hearing at around 80 decibels, or at about the sound level of a loud alarm clock.

Happy Patients:

We want to thank Dr. Johnson and the staff at the South Scottsdale office, for their prompt service, when I had a problem, with one of my hearing aids. They saw me within an hour of my call to their office and resolved the problem, in a few minutes. We appreciate a business that is so helpful and caring.

As a person who was just diagnosed with tinnitus and some hearing loss, I decided to see Dr. Gary Johnson and discuss if hearing aids would be beneficial to me. Dr. Johnson gave me a thorough examination and evaluation and recommended hearing aids for me to help with the hearing loss and help quiet the tinnitus. I have been wearing my new hearing aids for about 2 months now and I am so happy with them. Dr. Johnson did a wonderful job evaluating what would work for me. He is very pleasant, listens to the needs of the patient, answers all questions and makes you feel very comfortable. I have been helped with the hearing aids for both my tinnitus and hearing loss. Don’t hesitate to go see Dr. Johnson if you are in need of someone who can help with your tinnitus and hearing problems. He is the best in the business.
