An audiologist is a person with specialized training (at least a Master's degree in Audiology) qualified to provide professional assistance concerning communication problems associated with hearing impairment. Such an individual specializes in the prevention, identification, assessment and rehabilitation of hearing impairment.

Audiologists are certified by the American Speech/Language and Hearing Association (ASHA). ASHA awards certification to audiologists (9 months after graduation). The State of Iowa requires that audiologists meet these requirements prior to licensure from the Iowa Board of Speech/Language Pathology and Hearing Examiners. Finally, to dispense hearing aids, the audiologist must also meet the requirements of the Iowa Board of Hearing Aid Dealers.
