Our Equipment for Assessment

The audiology testing area consists of several different equipment and evaluation tools.

A comprehensive hearing test is the most common test for evaluating a patients hearing loss, if any. For this test, the patient will be seated in a sound-proof booth. They will be fitted with earphones and the audiologist will send through tones at different levels which they will respond by pushing a button or waving your hand. This gives the audiologist a good understanding of the levels the patient is hearing at. The audiologist might also conduct a speech audiometry test, which will include some words to be repeated at different sound levels. This will give the provider an understanding of what the patient's ability is to discriminate speech.

These results are charted onto an audiogram and then explained to the patient.

Another test that is frequently performed is a tympanometry test. This is done by inserting a soft tip into the patient's ear. Air pressure is changed to make the eardrum move back and forth. The results are displayed on a graph and can be very helpful in diagnosing problems in the inner ear.

The OAE machine, also known as Oto-acoustic emission testing, is a portable screening device which does not require a patients response and is mostly used in infants and patients with poor cognitive ability. The OAE can help an audiologist see which sound yielded a response and which did not.

After the tests are complete, the audiologist will discuss the results with the patient. The patient might receive information about hearing protection, amplification or recommendations for further testing.

DID YOU KNOW: if you have a hearing loss in both ears, but only choose only to wear a hearing aid in one ear, your unaided ear can become lazy.
