Adult Hearing Services

At Morton Plant Mease Hearing Health Center, we offer comprehensive services to assess and diagnose adult hearing loss.

Hearing Evaluation

Your first visit to a Morton Plant Mease Hearing Health Center will include a complete, non-invasive evaluation of your hearing using state-of-the-art equipment. It’s a lot more than “just a hearing test.” This is a thorough, 90-minute assessment to determine the exact type and degree of hearing loss, and how well or poorly you understand speech. It includes a complete case history, as well as visual inspection of the ear canal and eardrum. The audiologist may use the following tests:

  • Pure Tone Audiometry: This test measures your hearing ability at different pitches and at different volumes. A machine produces tones that you listen to via earphones and the results are recorded on a graph called an audiogram.
  • Word Recognition Testing: For this testing, an audiologist will test your ability to hear, understand and respond to speech by your repetition of simple words.
  • Basic Immitance Test Battery: These tests measure how the eardrum responds to sound. They provide information about the status of the middle ear, such as the detection of fluid in the middle ear or any perforation of the eardrum.

 Additional Testing Services

There are a variety of other procedures that assess the auditory system and determine hearing loss. They are sometimes used independently and sometimes to complement the standard series of audiologic tests.

  • Auditory Brainstem Response Testing (ABR):  This is used to evaluate how well sounds travel along the hearing nerve pathways to the brainstem. It can be used to estimate the hearing sensitivity of an adult who is unable to accurately complete a standard hearing test.
  • Otoacoustic Emission Testing (OAE):  OAEs are inaudible sounds produced by outer hair cells in the inner ear when they vibrate in response to an audible sound. The inaudible sound echoes back into the middle and outer ear and can be measured with a small, sensitive microphone placed in the ear canal. The presence or absence of OAEs is important in helping to identify hearing loss.
  • Videonystagmography (VNG) and Rotary Chair:  Our inner ear plays a significant role in helping us maintain our balance. Any disturbance in the inner ear may cause a feeling of dizziness. This test is used for patients with balance disorders to help determine the degree and location of a balance dysfunction.
