A “hearing doctor” typically refers to one of two professionals: an audiologist or an ENT (ear, nose, and throat doctor). Audiologists are the primary healthcare professionals who test, diagnose, and treat hearing loss and balance disorders across all ages. ENTs are medical doctors who handle the surgical and medical side of ear disease. Which one you need depends on what’s going on with your ears.
Audiologists: The Core Hearing Specialists
An audiologist holds a Doctor of Audiology (AuD) degree, which is a three-year doctoral program requiring a minimum of 850 hours of supervised clinical training. Many programs include an optional fourth-year clinical externship. After graduating, audiologists earn national certification and must complete 30 hours of professional development every three years to maintain it.
Audiologists are the professionals most people picture when they think of a hearing doctor. They run the full range of diagnostic hearing tests, fit and program hearing aids, treat tinnitus (ringing in the ears), and manage conditions like hyperacusis (painful sensitivity to sound). They are also the only professionals qualified to diagnose auditory processing disorder, sometimes called “hidden hearing loss,” where the ears work fine but the brain struggles to interpret what it hears.
What Happens During a Hearing Evaluation
A typical evaluation includes several tests, each measuring a different part of how your ear and brain process sound. Pure-tone testing asks you to respond to beeps at different pitches and volumes through headphones, mapping out exactly which frequencies you can and can’t hear. Speech testing measures how well you understand spoken words at various volumes. Middle ear tests use a small probe to check whether your eardrum and the tiny bones behind it are moving properly, which helps identify fluid buildup, infections, or structural problems.
For more complex cases, audiologists use tests that measure the electrical activity of your hearing nerve and brainstem, or record faint sounds produced by the inner ear itself. These are especially useful for newborns and young children who can’t raise their hand when they hear a beep.
Pediatric Hearing Testing
Testing a baby’s hearing requires a completely different approach than testing an adult’s. For infants, audiologists place small electrodes on the child’s head while they sleep and play clicking sounds through earphones. The electrodes record how the brainstem responds, giving an objective estimate of hearing ability without the child needing to do anything.
As children get older, audiologists adapt their techniques. For babies who can sit up and turn their heads, a method called visual reinforcement audiometry pairs sounds with a visual reward like a toy lighting up, teaching the child to look toward the sound. For toddlers who can follow simple instructions, the test becomes a game: drop a block in a bucket every time you hear the beep. Each of these methods lets the audiologist measure the type, severity, and pattern of hearing loss at an age when the child can’t describe what they’re experiencing.
ENTs: When You Need a Medical Doctor
An otolaryngologist, commonly called an ENT, is a physician who completes four years of medical school followed by a five-year residency in ear, nose, and throat surgery. Some pursue additional fellowships lasting one to two years in subspecialties like neurotology, which focuses specifically on the inner ear and hearing nerve.
ENTs handle the conditions that require medical or surgical treatment. If your hearing loss stems from chronic ear infections, a growth on the hearing nerve, fluid behind the eardrum, or a structural problem with the bones of the middle ear, an ENT is the specialist who can intervene. They also perform surgeries for cochlear implants and repair damaged eardrums.
Certain symptoms should prompt a visit to an ENT rather than starting with an audiologist. These include sudden hearing loss that develops over hours or days, pain or bleeding from the ear, pus or active drainage, recurring dizziness, hearing loss in only one ear (or significantly worse in one ear than the other), and pulsatile tinnitus, where you hear a rhythmic whooshing sound in sync with your heartbeat. These patterns can signal conditions that need medical imaging or surgical evaluation.
Hearing Instrument Specialists
A third type of professional you may encounter is a hearing instrument specialist. These are state-licensed providers trained specifically to evaluate common hearing loss in adults and fit hearing aids. They can program devices and make ear-mold impressions, but their scope stops there. They do not diagnose hearing loss or hearing disorders and are not trained to address tinnitus, balance problems, auditory processing issues, or pediatric hearing concerns. If you already know you need a straightforward hearing aid fitting, a hearing instrument specialist can help. For anything beyond that, an audiologist or ENT is the appropriate choice.
Balance and Dizziness Testing
Because the inner ear controls both hearing and balance, audiologists also evaluate and treat vestibular (balance) disorders. If you’re dealing with vertigo, chronic dizziness, or a sense that the room is spinning, an audiologist can run a series of tests that track your eye movements, measure how your body responds to changes in position, and assess how well your inner ear’s balance organs are functioning. Treatment often involves specific repositioning exercises or vestibular rehabilitation therapy, both of which audiologists are trained to provide.
Insurance Coverage for Hearing Visits
Medicare Part B covers diagnostic hearing and balance exams when ordered by a healthcare provider to determine if you need medical treatment. After the annual deductible, you pay 20% of the approved amount. Medicare also allows one visit per year to an audiologist without a referral for non-acute hearing conditions like gradual age-related loss, or for diagnostic services related to surgically implanted hearing devices. Original Medicare does not cover hearing aids or exams specifically for fitting hearing aids, which is a common source of frustration.
Private insurance varies widely. Many plans cover diagnostic evaluations but not hearing aids. Some employer plans and Medicare Advantage plans include partial hearing aid benefits. It’s worth calling your insurer before scheduling to find out what’s covered and whether you need a referral from your primary care doctor first.
Which Professional to See First
For most people noticing gradual hearing changes, difficulty following conversations, or ringing in the ears, an audiologist is the right starting point. They can run a full diagnostic workup, identify the type and severity of hearing loss, and either begin treatment or refer you to an ENT if the results suggest a medical cause. If you’re experiencing any of the red-flag symptoms listed above, like sudden loss, ear pain, or drainage, go directly to an ENT or ask your primary care doctor for a referral to one.
