Ear Doctors, Audiologists, Hearing Aid Specialists — What’s the Difference?

The types of hearing care professionals you might encounter in seeking help with your hearing loss differ in both their education and their skills.


Hearing Aid Dispensers or Hearing Instrument Specialists

Hearing instrument specialists are health care professionals who specialize in recommending and fitting appropriate hearing aid technology. They are typically up to date on the latest technology and accessories available in the field and are experienced in performing and evaluating basic hearing tests.

Hearing instrument specialists must be either board-certified or licensed by the state. Most states also require an apprenticeship or a specified period of practical experience before they are licensed.

Other common terms are licensed hearing aid dispensers and audioprosthologists.


Audiologists and Doctors of Audiology

You can think of an audiologist primarily as a hearing doctor. They are a licensed hearing health care professional who specializes in the diagnosis and treatment of hearing loss and balance disorders in adults and children.

Most audiologists hold a Doctor of Audiology (Au.D.) degree, though you might see other degrees within the field (Ph.D., Sc.D., M.S.).

They have comprehensive knowledge of the hearing and balance systems. They also have extensive training in sound reproduction, which is critical to the accurate fitting and adjustment of hearing aids.



Otolaryngologists are physicians (M.D.s) who specialize in diagnosing and treating diseases of the ears, nose, mouth, and throat. Trained in both medicine and surgery, otolaryngologists typically treat the types of profound hearing loss that require pharmaceutical or surgical treatment, like a cochlear implant. These types of hearing loss include loss caused by trauma, infection, or benign tumors in the ear.

After completing a medical course of treatment, otolaryngologists often refer patients to an audiologist for the prescription and fitting of digital hearing aids or counseling to help redevelop communication and language-recognition skills.

No matter what type of specialist you decide to see for your hearing needs, the most important factor is the overall experience they provide, which should include a comprehensive approach to diagnosing, treating, and reevaluating your hearing. Partnering with a professional who listens to your needs is critical to the success of your treatment plan.
