Types of Hearing Tests
The kinds of testing used to evaluate hearing in children and adults take several forms. These tests typically follow a screening, during which it is determined if further evaluation is necessary. While screenings can identify hearing loss, they do not definitively determine the scope of the loss or type of hearing loss.
The Pure Tone Test
Created to determine when a subject goes from registering sounds as “faint” to not registering sounds, this test offers specific pitches/frequencies from low to high, and the patient identifies when a sound is heard with a physical response, such as raising a finger or hand.
In older children and adults, the speech reception threshold records the faintest speech that can be heard, word recognition or the ability to correctly repeat back words at a comfortable loudness level.
Auditory Brainstem Response
This test provides information about the brain’s pathways used for hearing. This test uses electrodes on the head and the recording of brain activity in response to sound.
These tests are not the only tests of their kind, intended to determine the extent and type of loss, but each is indicative of a type of evaluation that one might expect as they being their journey toward corrective measures.
