Your first stop for hearing loss is usually your primary care doctor, who can check for simple causes like earwax buildup or an ear infection and then refer you to the right specialist. From there, most people end up seeing either an audiologist for hearing testing and hearing aids or an ENT (ear, nose, and throat doctor) for medical or surgical treatment. Which one you need depends on the type of hearing loss, how quickly it came on, and whether anything else is going on.
Start With Your Primary Care Doctor
A primary care doctor can perform basic screening right in the office. This typically includes a whisper test to check how well you hear soft sounds in each ear, plus a tuning fork test that helps distinguish between two broad categories: hearing loss caused by nerve damage in the inner ear versus hearing loss caused by something physically blocking sound, like fluid or earwax. If the tuning fork shows you hear better through bone vibrations than through air, that’s a clue something is blocking your ear canal or middle ear.
Your doctor will also look inside your ears with an otoscope to check for wax buildup, fluid, a perforated eardrum, or signs of infection. Many causes of temporary hearing loss, like impacted earwax or a middle ear infection, can be treated right there without a specialist visit. If the cause isn’t obvious or the hearing loss appears to involve nerve damage, your doctor will refer you to a specialist for more detailed testing.
Audiologists: Testing and Hearing Aids
An audiologist is a healthcare professional with a doctoral degree (Au.D.) who specializes in evaluating, diagnosing, and treating hearing loss and balance disorders. They perform comprehensive hearing tests that go well beyond what a primary care office can do, mapping exactly which frequencies you struggle with and how severe the loss is. They’re also the only professionals qualified to diagnose auditory processing disorder, sometimes called “hidden hearing loss,” where the ears work fine but the brain has trouble making sense of sounds.
Where audiologists really shine is in the technology side of hearing care. They are trained to fit and program hearing aids, bone-anchored hearing devices, cochlear implant processors, and assistive listening devices. If your hearing loss is the gradual, age-related kind or is noise-induced, an audiologist is typically the specialist who will manage your long-term care, adjusting your devices over time as your hearing changes.
One important distinction: audiologists don’t prescribe medication, order imaging like MRIs, or perform surgery. They aren’t trained in medical diagnosis beyond hearing and balance function. If your hearing loss turns out to have a medical cause that needs treatment beyond a hearing device, they’ll refer you to an ENT.
ENT Doctors: Medical and Surgical Treatment
An otolaryngologist, commonly called an ENT, is a physician who completed medical school followed by a five-year residency. ENTs handle hearing loss that has a medical or structural cause: chronic ear infections, a hole in the eardrum, abnormal bone growth in the middle ear, tumors, or any situation where medication or surgery might restore hearing.
ENTs bring something critical to the table that audiologists can’t: the ability to investigate what’s behind the hearing loss medically. A 55-year-old with hearing loss in only one ear might seem like a straightforward hearing aid candidate, but unilateral hearing loss can be the first sign of a tumor called an acoustic neuroma. An ENT knows to order an MRI before fitting a device. They can also order blood work, prescribe medication, and perform procedures like removing deeply impacted earwax or repairing a damaged eardrum.
For more complex ear conditions, there are ENTs who subspecialize even further. These doctors, called otologists or neurotologists, complete an additional two-year fellowship focused on the ear and the parts of the brain and nervous system connected to hearing and balance. They handle acoustic neuromas, other skull-base tumors, and cochlear implant surgery.
When Hearing Loss Is an Emergency
Sudden hearing loss in one ear that develops over hours or a few days is a medical emergency. Known as sudden sensorineural hearing loss, this condition needs treatment within 72 hours. Waiting longer dramatically reduces the chance of recovering your hearing, and delay often results in permanent loss.
This type of hearing loss can show up in unexpected ways. It doesn’t always feel like going deaf in one ear. It might present as a sudden muffled quality to sound, new ringing or buzzing (tinnitus), or even ear pain. It most commonly affects one ear and often strikes older adults with no obvious trigger. If you wake up one morning and one ear sounds like it’s underwater, go to an urgent care or emergency room that day. The standard treatment involves steroid therapy, and an ENT referral should happen immediately.
Tinnitus With Hearing Loss
Ringing, buzzing, or whooshing in the ears often accompanies hearing loss, and managing it usually involves both an ENT and an audiologist. The ENT investigates whether there’s a treatable medical cause. The audiologist handles the ongoing management, which can include hearing aids (which often reduce tinnitus by amplifying the sounds your brain is missing), masking devices that produce low-level white noise, or a structured program called tinnitus retraining therapy that combines sound therapy with counseling.
For the emotional toll that persistent tinnitus takes, a psychologist or licensed therapist trained in cognitive behavioral therapy can help. CBT doesn’t make the sound go away, but it changes how your brain responds to it, making it less distressing over time.
Hearing Loss in Children
Children with suspected hearing loss should see their pediatrician first, who will then refer to a pediatric audiologist or a pediatric ENT. The “pediatric” distinction matters here because testing a toddler’s hearing requires different techniques than testing an adult’s, and children’s ear anatomy and treatment needs differ significantly.
Newborns who don’t pass their initial hearing screening need complete hearing tests no later than 3 months of age. Babies who pass the screening but have risk factors for hearing loss should be tested between 24 and 30 months. For older children, signs worth watching for include unclear speech, frequently saying “huh?”, turning the TV volume unusually high, not following directions, or falling behind in school. Any of these warrants a prompt conversation with your child’s doctor.
Insurance and Referral Requirements
Whether you need a referral before seeing a specialist depends on your insurance. Medicare Part B covers diagnostic hearing and balance exams when ordered by a doctor, but it also allows one visit per year directly to an audiologist without a referral for non-acute hearing conditions like gradual age-related loss. Private insurance plans vary widely. Some require a referral from your primary care doctor, others let you book directly with an audiologist or ENT. Checking with your insurer before scheduling saves you from surprise bills.
It’s worth noting the difference between a diagnostic hearing evaluation and a hearing aid fitting. Diagnostic tests ordered to find a medical cause are more consistently covered by insurance. Hearing aid fittings and the devices themselves have much spottier coverage, though this has been improving in recent years, especially since over-the-counter hearing aids became available for mild to moderate loss.
Hearing Instrument Specialists
You may also encounter hearing instrument specialists, sometimes at retail hearing aid stores. These professionals are licensed to test hearing and fit hearing aids, but their training is narrower than an audiologist’s. They don’t diagnose hearing disorders, manage balance problems, or work with cochlear implants. If you already know you need a hearing aid for straightforward age-related loss and want help selecting and fitting one, a hearing instrument specialist can serve that role. But if you haven’t had a medical evaluation to determine the cause of your hearing loss, start with a doctor or audiologist instead.
