Individuals looking for hearing loss treatment face a number of challenges, including medical terms that may be unfamiliar and categories of health care professionals that may seem confusing. For instance, what is the difference between an audiologist and a hearing instrument specialist?

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.

Audiologists and Doctors of Audiology
An audiologist is a licensed hearing health care professional who specializes in the diagnosis and treatment of hearing loss and balance disorders in adults and children. You can think of an audiologist primarily as a “hearing doctor.” Most audiologists have completed a doctor of audiology (Au.D.) degree, though there are other doctoral degrees within the field (Ph.D., Sc.D., and others). Audiologists typically offer the following services:

  • Complete hearing exams
  • Audiology consultations
  • Comprehensive hearing treatment programs, which may include:
    • Fitting digital hearing devices
    • Adjusting digital hearing devices
    • Programming digital hearing devices
    • Maintenance of digital hearing devices
  • Treatment for balance disorders and tinnitus (ringing in the ears)

Audiologists possess comprehensive knowledge of the human auditory and vestibular systems, and they have extensive training in sound reproduction, which is critical to the accurate fitting and adjustment of hearing aids.

Hearing Instrument Specialists
In Indiana, Hearing Aid Dealers (some of whom refer to themselves at Hearing Instrument Specialists) are people who sell and fit hearing aids. Because they cannot diagnose hearing loss, hearing aid dealers offer free basic hearing tests, done for the purpose of fitting hearing aids (per Indiana statute).

In our Indiana, dealers are registered, and do not hold licensure.

Otolaryngologist
Otolaryngologists are physicians (M.D.s or doctors of medicine) who specialize in diagnosing and treating diseases of the ears, nose, mouth, and throat. As opposed to an audiologist, who is more like a “hearing doctor,” you can think of an otolaryngologist as an “ear doctor.” 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.
