    Diagnostic Hearing Evaluations

The audiometric evaluation consists of listening to tones through headphones and a special headband called a bone conductor. The patient responds to the tones by pushing a button. This test allows the hearing professional to evaluate the hearing status and the amount of hearing impairment. Speech testing is also performed to determine the patient's ability to understand words.

This test can be modified to test children's hearing as well.


Tympanometry is used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) and the conduction bones, by creating variations of air pressure in the ear canal.  It is an objective test of middle ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. This test should always be viewed in conjunction with pure tone audiometry. Tympanometry is a valuable component of the audiometric evaluation. In evaluating hearing loss, tympanometry assists in determining between sensorineural and conductive hearing loss.

    Otoacoustic Emissions (OAE) Testing

Otoacoustic emissions testing (OAE) is a simple, non-invasive test that can be used to screen hearing (particularly in neonates, infants, or individuals with developmental disabilities), and estimate hearing sensitivity.
This test requires the patient to be still and quiet during the testing.

    Tinnitus Evaluation and Treatment

Our audiologists will complete a comprehensive assessment to determine the cause of your tinnitus. We will then review your individual needs to develop a customized solution for you.

    Auditory Brainstem Response (ABR) evaluations

ABR testing is used to determine hearing status. It does not require a response from the patient so it is used for testing newborn infants, young children, and other patients who may not be able to respond appropriately during traditional hearing  testing. ABR testing is performed by attaching surface electrodes (similar to those used for an EEG) to the patient's head to measure the response of the hearing nerve. ABR testing is a safe and painless test of the auditory pathway and brainstem function in response to click-type stimuli.

    Dizziness Testing

Videonystagmography (VNG) testing evaluates the vestibular portion of the inner ear. This test is often usful in diagnosing patients with dizziness and vertigo symptoms. It is generally recommended to completed a hearing evaluation in addition to the VNG testing to identify inner ear disorders.

There are very specific instructions prior to this evaluation and it is very important that you follow them to obtain an accurate diagnosis.
