What Is Audiology?

An audiologist is a professional who specializes in the diagnosis and intervention of disorders of the auditory and vestibular systems of the body. Audiologists have attained either a master's or doctoral degree from an accredited university professional program, have attained state licensure and may carry national certification through ASHA (American Speech-Language and Hearing Association), ABA (American Board of Audiology) or AAA (American Academy of Audiology). Due to the rigorous training audiologists receive, including hundreds of hours of clinical experience prior to licensing, these professionals are uniquely qualified to accurately diagnose disorders of the complex auditory and vestibular systems.
