Audiologist or Hearing Instrument Specialist? Know The Facts
November 16, 2021
A person is holding a wooden block with the word truth on it.

Selecting a hearing care provider is an important decision. Why? Because finding the most qualified and dependable professional can mean the difference between being successful and satisfied with your hearing aids…or not. 


No doubt, you choose other health care professionals—your general practitioner, ophthalmologist, cardiologist, podiatrist, just to name a few—very carefully. Your hearing care professional is no different. Perhaps what makes the process most challenging are the many choices—from types of care providers to brands, levels and styles of hearing technology. Information can be confusing, even contradictory. Being educated about modern hearing healthcare and hearing aids allows you to make the most informed decision for your best outcome. 


Here’s what you need to know about the two kinds of professionals—audiologists and hearing instrument specialists—who are licensed to sell and fit hearing aids in the states Johnson Audiology serves—Tennessee and Georgia.


TWO TYPES OF HEARING CARE PROVIDERS: VERY DIFFERENT CREDENTIALS


An Audiologist’s credentials

Audiologists complete extensive university coursework to receive a clinical doctor-ate in audiology, earning their bachelor’s, master’s, and doctorate degrees over the course of eight years.


Through extensive graduate level coursework, what do they learn:

  • The neural pathways for transmission of sound from the inner ear to the cortex of the brain
  • Diagnostic testing for hearing loss, tinnitus, hyperacusis and other hearing-related disorders
  • The circuitry and components of a hearing aid and how to choose brand, style, and fit tailored to the individual patient
  • Assistive technology devices and how those can dovetail with a patient’s hearing aids and elevate the hearing experience
  • Theories of tinnitus and sound perception
  • Ear and hearing dysfunction and appropriate treatment options
  • Hearing conservation programs
  • Acoustic and digital modification strategies for hearing instruments
  • Inner ear balance disorders
  • Counseling techniques for patients and their family members regarding hearing loss and intervention. 
  • How to cultivate critical thinking skills and lifelong learning related to hearing function, amplification strategies, and tinnitus management
  • How to concentrate on superior patient care with compassionate counseling 


Throughout their graduate-level study, Audiologists are supervised in clinical rotations for all age levels in the following settings:

  • University clinic
  • Hospital
  • Public school system
  • Otolaryngology/ENT practices
  • Veteran’s Administration
  • Private practice


During each semester of the four-year graduate school enrollment, a student will:

  • Participate in 12 hours of coursework in addition to six hours of clinical work with patients
  • Routinely participate in clinical work with aural rehabilitation therapy to gain a better understanding of the work performed by their speech-language pathology colleagues
  • Log nearly 2,000 patient contact hours during their fourth year of graduate study, in addition to their previous hours acquired during their first three years of graduate study


Applicants for licensure as an Audiologist in Tennessee must: 

  • Earn a doctoral degree with an emphasis in audiology from an accredited institution
  • Have a current certificate of clinical competence (CCC-A) from American Speech-Language Hearing Association (ASHA) and/or complete 1,820 clock hours of supervised clinical practicum by a licensed or certified audiologist and pass the Praxis exam for audiology.
  • Complete ten hours of continuing education every year to maintain their license. 


A hearing Instrument specialist’s training

A dispenser/hearing instrument specialist (HIS) is the second professional permitted to sell and issue hearing aids in Tennessee and Georgia. 


For initial apprentice licensure, an HIS must:

  • Be at least 18 years old
  • Have two years of college coursework in any subject (does not have to be in audiology or a related subject)
  • Pass a written exam


Upon apprenticeship completion, an HIS must: 

  • function under the direct supervision of a sponsoring, licensed hearing instrument specialist (HIS) for at least three months
  • Complete 60 hours of classroom coursework


A HIS must: 

  • Complete 20 hours of continuing education during the two calendar years that precede the licensure renewal year with two hours of the 20-hour requirement pertaining to state statutes and rules concerning hearing instrument specialists.


As you consider who you want to trust as your lifelong partner on your journey to healthier hearing. ask yourself these questions:


  • Which hearing provider—an Audiologist or a HIS—has the highest level of education?


  • Which provider has shown the greatest evidence of commitment to his or her field through time and personal resources invested in honing knowledge and skills?


  • Which provider spends the most time working with patients in a supervised, training setting before being credentialed to work with those with hearing loss solo?


  • Which type of provider routinely verifies and files your insurance benefits for hearing health care?


  • Which provider conducts a full diagnostic hearing test in a rated, sound-proof booth?


Misconceptions and Facts


Misconception

  • An Audiologist’s education concentrates on the diagnostic procedures rather than hearing aid fitting.

Fact

  • Audiologists formally study hearing aid technologies from multiple manufacturers while in graduate school and continue to do so throughout their careers. Notably, most of the professionals from the hearing aid manufacturers that lead trainings are degreed audiologists not hearing instrument specialists.


Misconception

  • Hearing instrument specialists offer the same type of hearing tests as an audiologist

Fact

  • Hearing instrument specialists are not licensed to perform audiological exams. Therefore, their assessments are not considered diagnostic hearing tests but rather basic hearing screenings. Audiologists, however, do full audiologic testing in a rated, sound-proof booth. Audiologists are also trained and licensed to conduct diagnostic testing specifically for those with tinnitus and for patients who are candidates for cochlear implantation, testing which hearing instruments specialists cannot legally perform.


Misconception

  • Hearing instrument specialists offer free hearing tests because they care more about their customers

Fact

  • Most audiologists offer patients the benefit and convenience of filing the patient’s diagnostic hearing test to Medicare, which covers testing. Notably, it is insurance fraud for an Audiologist to bill Medicare for one patient and then provide a free evaluation for another patient. Therefore, audiologists cannot legally provide free hearing testing if they are a Medicare provider. Since most hearing dispensers offer “free” testing this automatically means they are not working with Medicare so customers lose out on that benefit. 


Here are some tips when searching for your hearing care professional:


  • Ask for the provider’s credentials. A doctor of audiology has the credentials Au.D. following his or her name. If you see HIS following the person’s name, you know that person is a minimally trained hearing instrument specialist.
  • Look for an Audiologist who works with several hearing aid manufacturers so that your technology can be tailored to your unique hearing loss. 
  • Ask if you are entitled to a trial period. Each patient is a unique individual. You deserve to work with a professional who spends times assessing and addressing your personal hearing concerns, goals, desires and budget. 
  • Do not buy hearing aids by mail or internet that claim patients do not need direct contact with their hearing health-care professional.

Like anything new in life, adjusting to hearing aids can take time and perseverance to achieve the best results. Yet many people are too quick to give up, not allowing the brain the chance to relearn how to hear or not giving themselves the opportunity to become accustomed to the use and maintenance of their devices. “We meet so many people who wait—who convince themselves their hearing is not ‘bad enough’ or that they can just get by. But untreated hearing loss quietly steals moments, connection, and joy. At Johnson Audiology, we understand the fear, the frustration, and the doubt. That is why we offer more than hearing aids—we offer compassion, answers, and a partner you can trust. You don’t have to do this alone. Let us help you hear your life again,” says Dr. Megan Johnson, audiologist and owner of Johnson Audiology. “Hearing aids should never be an experience where a person is fit with devices and then they never see their hearing care provider again. To ensure patient success, Johnson Audiology seeks to be a lifelong partner on a person’s journey to healthy hearing, someone who is there at every turn,” says Dr. Megan Johnson, audiologist and owner of Johnson Audiology. What are the most common reasons why people give up on hearing aids and why is it important to stick with it? Reasons why people might give up on hearing aids An adjustment period It is your brain that hears, not your ears. The ears transmit sound to the brain where it is interpreted. Dr. Johnson explains, “When a person’s brain has not been stimulated by sound because of hearing loss and then sound is restored with hearing aids, it can take some getting used to. For some people, it takes more than one appointment to get them up to full sound prescription, stair stepping up gradually to let the brain adjust. The brain’s capacity to do this is called neural plasticity .” Research by the University of Colorado Boulder’s Hearing Epidemiology and Research Diagnostic Laboratory has revealed that what the brain can experience impacts within weeks rather than years when hearing loss reaches a certain level. Dr. Johnson says, “The brain’s temporal lobe is where much of hearing and sound interpretation happens. Electroencephalogram (EEG), which is a medical test that measures the electrical activity of the brain, shows that in the presence of hearing loss, the brain will recruit areas assigned to other tasks—like vision—to compensate. The trouble is that this extra cognitive load can tax those areas. However, after treatment with hearing aids, brain recruitment is shown to reverse, partially or fully.” The adjustment period for hearing aids tends to be more seamless for those who have not been without sound for years and years. Dr. Johnson says, “I always encourage people to get their hearing checked when they first notice they are struggling. Sooner is always better.” An investment in quality of life People often make an investment in their health and well-being—for example, purchasing glasses, getting a knee replacement, straightening their teeth—and yet many relegate hearing to the backburner because of cost. Dr. Johnson says, “I’ve seen many patients struggle with hearing aids after buying inferior products in an attempt to save money. Without the guidance of a hearing care provider, even the best device can quickly become ineffective and frustrating.” Dr. Johnson encourages making hearing a priority and budgeting for your hearing health. Perceived benefits and ease of use Getting in the routine of putting hearing aids in each day and being diligent about regular cleaning and maintenance might be a challenge that some face and which deters them from being successful with their aids. “At Johnson Audiology, we offer a plan for regular in-office cleaning and maintenance, easing the task of upkeep for patients. Plus, our offices have dedicated walk-in hours that do not require an appointment. We are here to answer questions, make hearing aid adjustments, and much more as we seek to help people safeguard their investment in hearing technology and make the process easy and convenient.” Family attitudes and support When it comes to hearing aids, having a support system can be crucial to success. “In my 20 years as an audiologist, I have seen the immense benefits when a person’s family members show patience and support during the adjustment period with new hearing aids,” said Dr. Johnson. What about patients who do not have that familial encouragement? Dr. Johnson says, “We are your support system. That’s where our caring and professional audiologists, audiology assistants, and patient care coordinators can lend a helping hand. Success with hearing aids is our goal for every patient, so we promise to be there every step of the way.” Why is healthy hearing so important Hearing loss is a family affair The positive impact of treating hearing loss is often manifested most significantly through improved relationships with family and friends. Hearing loss leads to miscommunication. It can also cause mounting frustration as family members must constantly repeat every sentence. Dr. Johnson comments, “Living with the TV blaring can put a strain on others living in the same household. Untreated hearing loss can quietly tear at the fabric of your relationships. When words go unheard and conversations fade, love and connection start to suffer, and that pain is felt by all involved.” Healthy hearing can help the brain stay sharp and pliable For many years, researchers at Johns Hopkins University have been studying the relationship between hearing loss and dementia. While there is still much left to discover, increasingly scientists recognize healthy hearing as a key factor in maintaining a healthy brain and potentially decelerating the risk of dementia, like Alzheimer’s disease. Dr. Johnson says, “It seems logical that when certain areas of the brain are not stimulated by sound, they atrophy. In fact, research suggests an actual reduction in the physical size of the brain, especially in areas where sound processing and memory take place.” She goes on to say that “while there are many risk factors that individuals cannot control about the effects of aging on the brain, hearing is definitely one that can and should be addressed.” Healthy hearing keeps a person engaged in life Humans are social beings. Since hearing loss can impair effective communication, it is not difficult to understand how it also could lead to social isolation, which can cause increased anxiety and depression. “Conversely, addressing hearing loss can keep a person engaged in life and connected to family and friends,” Dr. Johnson says. Falls and other health risks The ears have two main functions. Hearing is one that most of us learn as youngsters, but the ears also play a major role in helping a person maintain their balance and knowing where their body is in space. “The fluid, or endolymph, in the ear’s semicircular canals is what helps a person do things like stand up from a seated position without falling, walk a straight line, and not run into a door frame when turning a corner into a room,” says Dr. Johnson. In the presence of hearing loss, the reduction in acoustic signals impairs a person’s ability to process spatial information and can mean a higher risk for falling. In turn, falling can lead to broken bones and other injuries and a cascading effect of hospital stays and loss of independence.
