Let us answer your questions.

What is Audiology?

Audiology is the study of hearing and hearing related disorders. An audiologist is the professional who specializes in evaluating and treating people with hearing loss. Audiologists have extensive training and skills to evaluate the hearing of adults, infants and children of all ages. Audiologists conduct a wide variety of tests to determine the exact nature of an individual’s hearing problem. Audiologists present a variety of treatment options to patients with hearing impairment. Audiologists dispense and fit hearing aids, administer tests of balance to evaluate dizziness, and provide hearing rehabilitation training. Audiologists work closely with physicians when the hearing problem needs medical or surgical evaluation.
