Why evidence-based care matters in audiology
The 3 key takeaways:
- Clinical and research audiology work together — clinical audiologists treat patients, while research audiologists generate the evidence that guides care.
- The difference is about role, not importance — one delivers care in real time, the other improves how care is delivered over time.
- Better hearing care depends on both — every test, device, and treatment approach comes from this ongoing collaboration.
Every test an audiologist runs in a clinical setting — every protocol for fitting a hearing aid, managing tinnitus, or evaluating balance — exists because researchers have studied those questions carefully enough to produce reliable answers.
Clinical audiology and research audiology are not competing versions of the same thing. They are complementary roles within the same field — one focused on patient care, the other on advancing knowledge.
For patients, understanding this relationship helps explain where the recommendations you receive come from, and why the field changes over time. For students, it highlights a key decision: whether you want to work directly with patients or contribute to the science behind their care.
This article examines both branches of audiology, what each involves, how they relate to each other, and what the distinction means in practical terms.
Clinical audiology: What patient care actually looks like
Clinical audiology is the practice-facing side of the field — the work that happens in soundproof testing booths, cochlear implant clinics, hospital audiology departments, veterans’ facilities, school systems, and private practices.
Clinical audiologists:
- Evaluate hearing and balance
- Diagnose conditions
- Fit and program hearing aids and implants
- Manage tinnitus and vestibular disorders
- Provide counseling and rehabilitation
- Collaborate with ENTs, neurologists, speech-language pathologists, and others
Their work involves the application of audiological research in order to provide patient-centered care.
Education required for an Au.D. in audiology
The credential for this role in the U.S. is the Au.D. (Doctor of Audiology) — a four-year clinical doctorate that includes supervised training and a full-time externship. An Au.D. program doesn’t just train clinical audiologists to run hearing tests — it prepares them to translate complex science into real-world decisions for individual patients.
What makes clinical audiology unique
- Direct, face-to-face patient care
- Real-time problem solving
- Long-term patient relationships
- Focus on outcomes like communication, quality of life, and function
Research audiology: how the science of hearing advances
Research audiology is the investigative side of the field — focused on discovering new knowledge and improving existing care. Research audiologists are scientists first and the range of questions they investigate is vast. They may study something like cochlear hair cell damage, hearing aid performance, tinnitus treatments, cognitive effects of hearing loss, or public health trends.
Research audiologists:
- Design and conduct studies
- Analyze data and publish findings
- Develop new technologies and treatment approaches
- Inform clinical guidelines
Research audiologists don’t treat patients directly, but their work shapes how every patient is treated.
Research audiologists contribute to the cumulative body of knowledge that the field draws on when it sets clinical standards, updates treatment protocols, and develops new technologies.
Education required for a Ph.D. in audiology
The primary credential for a research career in audiology is a Ph.D., with a focus on the production of original research: students develop expertise in a specific area, master research methodology and statistical analysis, and complete a dissertation that makes an original contribution to scientific knowledge. The National Institute on Deafness and Other Communication Disorders (NIDCD) is the primary federal funder of audiology and hearing science research in the United States.
Where research audiology shows up in real life
- Hearing aid algorithms that improve speech clarity
- Cochlear implant programming strategies
- Early hearing detection programs for infants
- Evidence-based tinnitus treatments
How clinical and research audiology work together
These two branches are tightly connected, and constantly inform each other.
Research informs clinical care
Modern audiology is built on evidence. For example, the way audiologists fit hearing aids today — using real-ear measurement to verify that prescribed amplification is actually being delivered at the eardrum — reflects decades of research demonstrating that this approach produces meaningfully better outcomes than fitting without verification.
When new evidence emerges, clinical care changes.
Clinical care drives new research
The reverse is equally true. Clinicians often notice patterns that research hasn’t explained yet. This might look like:
- a patient whose hearing aid outcomes are consistently poor despite technically correct fitting
- a pattern of symptoms that doesn’t fit established diagnostic categories
- a subgroup of patients who respond unusually well or poorly to a particular intervention
These observations become research questions, driving future studies. Some of the most important questions in audiology research have originated in the clinic, rather than in the lab.
The clinician-scientist bridge
Some professionals hold both an Au.D. and a Ph.D.
These clinician-scientists can design research that is informed by genuine clinical experience, ask questions that matter to practitioners, and translate findings back into clinical language in ways that pure researchers sometimes cannot. They play a critical role in connecting science to care.
Clinical vs. research audiology: side-by-side
| Feature | Clinical Audiology | Research Audiology |
|---|---|---|
| Primary focus | Patient care | Scientific discovery |
| Degree | Au.D. | Ph.D. |
| Daily work | Testing, treatment, counseling | Studies, data, publications |
| Work setting | Clinics, hospitals, schools | Universities, labs, industry |
| Patient interaction | Direct | Limited or none |
| Impact | Immediate | Long-term |
Where audiologists work: clinical vs. research settings
The settings where audiologists work reflect the fundamental divide between clinical care and research. Each environment plays a distinct role in how hearing healthcare is delivered and improved.
Clinical settings
Clinical audiologists practice across a diverse range of settings, and the day-to-day experience of the job varies considerably depending on where a clinician works:
- Private practices — typically focused on hearing tests, hearing aid fittings, and follow-up care; some focus on specific populations
- Hospitals and academic medical centers — often handling more complex cases, including cochlear implants, vestibular specialty clinics, and inpatient consultations
- Veterans Affairs medical centers — one of the largest employers of audiologists in the United States, given the high prevalence of hearing loss and tinnitus among veterans
- ENT and otolaryngology practices — audiologists embedded in ENT offices provide diagnostic services and device fitting in close collaboration with physician colleagues
- School systems and early intervention programs — supporting children with hearing loss in educational settings and working with early intervention teams for infants and toddlers
- Teleaudiology platforms — a growing segment providing remote hearing assessment and hearing aid follow-up services
Research settings
Research audiologists are found in a variety of settings, each with its own culture and research agenda:
- Universities and academic departments — the most common home for basic and applied hearing science research, typically involving graduate student training alongside research activity
- Academic medical centers — often structured around clinical research that bridges laboratory findings and patient outcomes, frequently in collaboration with otolaryngology, neurology, and rehabilitation medicine departments
- Government research agencies — the NIDCD at the National Institutes of Health conducts intramural research and funds extramural work at universities and medical centers across the country; the Department of Veterans Affairs also maintains a significant hearing research program given the high rates of hearing loss and tinnitus among veterans
- Hearing aid and cochlear implant manufacturers — industry research and development teams include Ph.D.-level audiologists and hearing scientists who work on signal processing, device design, fitting algorithms, and outcomes research
- Non-profit research institutes — organizations such as the Boys Town National Research Hospital conduct hearing and communication science research outside of the traditional university structure
Evidence-based practice: where both paths meet
Evidence-based practice (EBP) is where both paths meet. EBP integrates the best available research with clinical expertise and patient values in order to make smart clinical decisions.
EBP in practice
In practice, EBP means clinical audiologists must stay current with research, evaluate the quality of evidence behind clinical claims, and apply well-supported findings to patient care — while also recognizing the limits of that evidence.
This is what makes the relationship between research and clinical audiology more than academic. For example, when new research shows that a hearing aid fitting method leads to better patient outcomes, it can change how thousands of audiologists practice, ultimately improving care for millions of patients.
What this means for patients
If you are a patient, you may never think about the research infrastructure behind your care, and you don’t need to. But it is worth knowing that the recommendations your audiologist makes, the devices they prescribe, and the way they interpret your test results are all anchored in a body of evidence that researchers worked for years to build.
When your audiologist tells you that early hearing aid adoption is associated with better long-term outcomes or that a specific type of hearing loss warrants a referral — they are relying on years, if not decades, of research.
From our audiologist, Dr. Jessica Hinson, Au.D.: how research shows up in real patient care
Research published by Ph.D. audiologists shapes the way we practice in clinics across the world. Newly developed speech-in-noise tests allow us to see in real time how a patient processes speech in noisy environments, which can improve hearing aid fittings and counseling outcomes.
For example, in March 2026, a new hearing aid fitting formula, NAL-NL3, was introduced and is already being implemented into clinical software to help audiologists improve patient outcomes.
As a clinical audiologist, staying current with research is essential. Subscribing to journals like the American Journal of Audiology helps us keep up with new developments as they emerge. The knowledge gained through this research directly supports evidence-based care in the clinic.
Using these evidence-based practices, combined with an individualized treatment plan, helps ensure patients have the best chance to improve their hearing, balance, and communication.
Why evidence-based care matters in audiology
Clinical and research audiology serve different roles, but share the same goal: better hearing care. One delivers care today. The other improves care for tomorrow.
The researcher designing a cochlear implant signal processing study and the audiologist programming that implant for a child hearing their parent’s voice for the first time are engaged in the same fundamental project, just from different vantage points.
Together, they ensure that audiology continues to evolve, and that patients benefit from that progress.

Frequently Asked Questions
Can a clinical audiologist also do research?
Yes, though the depth and formality of that research varies considerably. Many Au.D.-trained audiologists contribute to clinical research in their workplaces — participating in data collection for multi-site studies, contributing to quality improvement initiatives, or publishing case reports. Audiologists who want to lead independent research programs typically pursue a Ph.D. or the combined Au.D./Ph.D. degree, which provides the methodological and statistical training that original scientific investigation requires.
How does research become part of clinical care?
The path from research finding to clinical practice typically runs through peer-reviewed publication, review by professional bodies like ASHA and the AAA, incorporation into clinical practice guidelines, and continuing education programming for practitioners. That pathway can take years — which is why the most current research findings are sometimes ahead of what you’ll find in widespread clinical use, and why evidence-based practice frameworks emphasize the importance of staying current with the literature.
What is translational research in audiology?
Translational research refers to investigation specifically designed to bridge basic science discoveries and clinical application — to “translate” laboratory findings into practices, treatments, or technologies that benefit patients. An example might be research that takes basic science findings about cochlear hair cell damage mechanisms and investigates whether a pharmacological intervention might reduce that damage in humans. Translational research is an increasingly prioritized category at funding agencies like the NIDCD.
Are clinical trial results available to patients?
Yes. Clinical trials in audiology and hearing research are registered at ClinicalTrials.gov, where patients can search for studies by condition, treatment, and location — including opportunities to participate in research. Many academic audiology programs also publish their ongoing research publicly, and results of completed trials are available through medical databases like PubMed once published.
Who funds audiology research?
The largest public funder of hearing and communication research in the United States is the National Institute on Deafness and Other Communication Disorders (one of the institutes of the NIH), the VA, private foundations, hearing aid manufacturers, and cochlear implant companies. However, industry-funded studies are evaluated with appropriate attention to potential conflicts of interest.
