Audiologist vs. Hearing Instrument Specialist – What’s the difference?

In Ontario, audiologists have advanced training and can assess all ages, including children, while hearing instrument specialists mainly work with adults.

Audiologists

- Complete a 2 to 3-year master’s in audiology and are licensed by the College of Audiologists and Speech-Language Pathologists of Ontario (CASLPO). Can diagnose hearing and balance disorders in both adults and children. This includes specialized testing for infants and young children, which requires advanced clinical training. They also fit hearing aids, manage tinnitus, and assess complex hearing or balance conditions.

Hearing Instrument Specialists (HIS)

- Hold a 2 to 3-year college diploma from an accredited Hearing Instrument Specialist program and are licensed by the Association of Hearing Instrument Practitioners of Ontario (AHIP). Provide hearing tests and hearing aid fittings, but their scope is focused on adults. They cannot test or diagnose children’s hearing, and must refer pediatric cases to an audiologist. Hearing instrument specialists are experts in helping adults find the right hearing aids, fine-tune performance, and provide ongoing support. They often offer more personalized service, practical advice, and better value for those seeking hearing solutions.

Key distinction: Audiologists are trained to test and manage hearing for all ages, including children, while hearing instrument specialists primarily work with adults for hearing aid services.

Best Choice for Hearing Aids: Hearing Instrument Specialist

In Ontario, both audiologists and hearing instrument specialists can fit and sell hearing aids. However, hearing instrument specialists focus specifically on hearing aid selection, fitting, and ongoing support.

They’re experts in helping adults find the right technology, adjust comfort settings, and maintain their devices, often providing more personalized service and better value.

While audiologists also fit hearing aids, their training is broader and often geared toward diagnosing complex or pediatric hearing issues.

For most adults purchasing hearing aids, a hearing instrument specialist is the best choice for expertise, convenience, and continued care.
