A Hearing test by definition is the procedure used to assess one’s hearing. Hearing test can be both subjective and objective. For subjective test like pure tone audiometry, it requires the attention of the person being tested. Objective test on the other hand, like the Auditory Brainstem Response (ABR) test, it doesn’t. But in general, either of the types of test both will give the impression how well or how bad a person’s hearing is.
