The difference between Audiologists & Hearing Instrument Specialists

Professionals who diagnose and treat hearing loss can vary significantly in terms of training & education.  Today, it is still customary for someone to get their hearing tested and a hearing aid fitted by someone and still not know their qualifications.  So how do you know which professional to choose to treat your hearing loss?  This is why understanding the differences between  Audiologists and Hearing Instrument Specialists are important to consider when treating your hearing loss.

Making an informed decision when it comes to identifying the Best hearing care professional for you, is critical in achieving great outcomes with hearing aids.  Since most individuals with hearing loss are more often enticed by special offers on hearing aids, little attention is paid to the professional who will be performing treatment with those hearing aids.

There are two types of professionals who can legally dispense hearing aids, Audiologists and Hearing Instrument Specialists (HIS).  Hearing Instrument Specialists (HIS) are also sometimes referred to as Hearing Aid Dispensers.  The distinction between Audiologists and Hearing Instrument Specialists can be confusing, so we will attempt to clear up some of that confusion in this article.  

How are they similar?

There are a number of similarities between these two distinct professionals.

  • They both must be Licensed to perform Hearing Tests.  These tests generally include Pure-tone Air Conduction and Bone Conduction testing (to check for the kinds of frequencies you might have difficulty hearing) as well as Speech testing to determine your comprehension of speech.
  • They are both Licensed to Dispense Hearing Aids.  All tests require licensure to sell and fit hearing aids.  However, each state has their own licensure requirements that are different for each type of professional.
  • You can go to either for hearing aid care.  Both professionals can dispense, program, repair, clean, & maintain hearing aids.
  • Both can follow Best Practices when selecting, fitting, and programming hearing aids.  Best Practices are a series of procedures that can be performed to ensure that you receive the maximum amount of benefit from hearing aids.  
  • Both can work with adults.  If you are above the age of 18, you can be treated by either an Audiologist or Hearing Instrument Specialist.

How do these professionals differ?

At first glance, there seems to be minimal differences between an Audiologist and Hearing Instrument Specialists.  However, there are some significant differences between these two types of professionals.  Here are the most important differences.

Education level:  Audiologist are required to have a Master’s Degree in Audiology, a clinical Doctorate in Audiology (AuD), or Doctor of Philosophy (PhD) in Audiology.  This means that all audiologists are required to have a 4-year Bachelors Degree and an additional 2 year Master’s Degree or 4-6 year Doctoral Degree to practice Audiology.  Currently, to become an Audiologist, there is no longer a Master’s level option.

Educational requirements for Hearing Instrument specialists can vary widely between states.  Most states only require a High School Diploma, and on-the-job training alongside another Hearing Instrument Specialist for a 1-2 year time period.  Some Hearing Instrument Specialists receive formal training from a 2-year Hearing Instrument Sciences program before obtaining state licensure.

Scope of Expertise:

Hearing Instrument Specialists’ scope of practice is more limited than Audiologists.  Hearing Instrument Specialists can only perform testing for the purpose of dispensing hearing aids, and dispense and fit hearing aids.   Audiologists on the other hand have a larger scope of practice which includes:

  • Hearing Aid Dispensing & Fitting
  • Comprehensive Audiologic Testing
  • Balance Testing
  • Balance Treatment
  • Cochlear Implants
  • Bone Anchored Hearing Aids
  • Intraoperative Monitoring
  • Cerumen (earwax) removal
  • Tinnitus Evaluation & Management

Areas of work:

Hearing Instrument Specialists typically work in a private practice setting such as a Hearing Aid Dispensing Clinic.  Audiologists work in a variety of settings to include Hearing Aid Dispensing Clinics, Hospital Audiology Departments, Physical Therapy Centers, Schools, Balance Clinics, & Otolaryngology (ENT) Clinics.  Since an Audiologist’s scope of practice is so broad, they often work with other Medical professionals to diagnose and treat a variety of medical conditions related to the ear. 

Pediatric Hearing Care:

Only Licensed Audiologists can work with children below the age of 18.  Audiologists support children who have deafness, hearing loss, and difficulties with speech or communication.  Pediatric audiologists are specifically trained on how to diagnose and treat hearing loss in children.

Which one should I pick?

Depending on where you live, you may not have a choice between an Audiologist or Hearing Instrument Specialist when looking for hearing aids.  However, if you are concerned about the medical implications of your hearing loss, or education level of the provider you see, then an Audiologist may make the most sense.  Also, if you are a first-time hearing aid wearer, then you may feel more comfortable with an Audiologist and their formal knowledge of the auditory system.  

However, perhaps the single most important factor when deciding between an Audiologist and Hearing Instrument Specialist, is whether or not they follow Best Practices.  Best Practices are a long list of procedures that must be followed if you want to achieve your highest level of performance with hearing aids.  There are Audiologists and Hearing Instrument Specialists alike who follow these Best Practices, & ignore Best Practices.
