Decoding Hearing Healthcare: Understanding the Difference Between an Audiologist and a Hearing Instrument Specialist
Oct 22, 2026
It often starts with small changes. You find yourself turning up the TV a little louder or struggling to catch key parts of a conversation at a local restaurant. You know it may be time to get your hearing checked, but one question can make the next step feel confusing: Who should you see?
You may have come across titles such as audiologist and hearing instrument specialist. While both professionals help people hear better, their qualifications, training, and scope of practice differ significantly.
Understanding these differences can help you make a confident and informed decision about your hearing care and take the right steps toward protecting your long-term hearing health.
Let’s explore what sets these two professions apart and how to determine which one best suits your needs.
What is an Audiologist?
Audiologists are highly trained healthcare professionals who specialize in hearing and balance. They complete 7–8 years of study beyond high school, earning a Doctor of Audiology (Au.D.) degree or a Master of Science degree.
They must also complete extensive supervised clinical training, pass a national examination, and obtain state licensure, which they maintain through continuing education.
What Can an Audiologist Do?
Perform comprehensive hearing evaluations to assess the type, degree, and possible nature of hearing loss.
Evaluate middle-ear function using techniques such as tympanometry and acoustic reflex testing.
Identify signs of medical conditions that may require referral to an ear, nose, and throat (ENT) physician or another healthcare professional.
Evaluate tinnitus (ringing or other noises in the ears) and provide appropriate counseling and management.
Develop individualized treatment plans based on hearing test results, medical history, and the patient’s specific communication needs.
Provide hearing rehabilitation and recommend appropriate solutions, including hearing aids, assistive listening devices, and cochlear implant evaluations.
Fit, program, and verify hearing aids to help ensure they are appropriately matched to a patient’s hearing needs.
An audiologist’s education and clinical training provide a broad foundation for evaluating hearing health, identifying potential concerns, and developing individual treatment plans, which may extend beyond hearing aids.
What is a Hearing Instrument Specialist?
A Hearing Instrument Specialist (HIS) is a non-audiologist who fits and dispenses hearing aids. In Pennsylvania, the path to becoming a licensed HIS differs significantly from that of an audiologist.
An HIS must hold a high school diploma, complete 6 months of required training, and pass a state licensing exam. Once licensed, specialists must complete ongoing continuing education to maintain their Hearing Fitter License and stay current with advances in hearing aid technology.
What Can a Hearing Instrument Specialist Do?
A hearing instrument specialist can:
Perform some hearing assessments permitted under applicable state law.
Help customers select appropriate hearing aid technology.
Provide instructions on hearing aid use, care, and maintenance.
With a focus on hearing aid selection and support, an HIS can help individuals make informed decisions about their devices and get the most out of their use.
Why Our Education Makes a Difference
Hearing aids play an important role in hearing healthcare, but choosing the right treatment begins with understanding your individual needs. An audiologist’s comprehensive clinical training helps ensure that care extends beyond selecting a device to address your overall hearing health and long-term goals.
At ASA Hearing Care Center, we’ve built our practice on a foundation of trust, expertise, and compassionate care since 1984. Our clinical team includes master’s- and doctoral-qualified audiologists, bringing advanced training and a comprehensive understanding of hearing and balance health to every patient we serve.
