For most adults noticing hearing trouble, an audiologist is the best first stop. Audiologists are doctoral-level specialists who diagnose hearing loss, determine its type and severity, and fit hearing aids or other devices. But depending on the cause, timing, and severity of your hearing loss, you may also need an ear, nose, and throat doctor (ENT), or you might be able to skip a professional visit entirely and buy hearing aids on your own.
Audiologists: The Go-To for Diagnosis and Hearing Aids
An audiologist holds a doctoral degree in audiology and is trained to run a full battery of hearing tests, diagnose the type and degree of loss, and recommend treatment. A standard diagnostic evaluation typically includes a comprehensive audiology exam that measures your hearing ability across different frequencies and compares it to age-appropriate norms, tympanometry to check how well your eardrum and middle ear bones are functioning, and speech-in-noise testing that measures how well you follow conversation in a noisy room.
Audiologists are also the only professionals qualified to diagnose auditory processing disorder, sometimes called “hidden hearing loss,” where you can technically hear sounds but your brain struggles to make sense of them. They also treat tinnitus (ringing in the ears) and hyperacusis (painful sensitivity to everyday sounds).
If hearing aids are the right solution, an audiologist selects, fits, and programs them. They handle follow-up adjustments and long-term management. For children who fail a school hearing screening, an audiologist is the recommended next step for diagnosis before any further referrals.
ENT Doctors: When the Cause Is Medical
An ENT (otolaryngologist) is a physician who can diagnose and treat the medical or structural causes behind hearing loss. You’d see an ENT when the problem might be treatable with medication or surgery rather than hearing aids. Conductive hearing loss, where something physically blocks or disrupts sound transmission through the ear canal, eardrum, or middle ear bones, can often be reversed with medical or surgical intervention. An ENT handles those cases.
Some ENTs subspecialize further as otologists, focusing exclusively on diseases of the ear. If your audiologist finds something in your test results that points to a medical issue, they’ll refer you to an ENT for further workup.
Sudden Hearing Loss Is a Medical Emergency
If you lose hearing in one or both ears all at once, or over just a few days, treat it as an emergency. Go directly to an ENT or an emergency room. Sudden sensorineural hearing loss must be treated within 72 hours to have the best chance at recovery. Missing that window greatly reduces the likelihood of getting your hearing back.
People with sudden hearing loss often discover it when they wake up in the morning or try to use a phone on the affected side. Some hear a loud “pop” right before the hearing disappears. Dizziness, a feeling of ear fullness, or sudden tinnitus alongside rapid hearing loss are all reasons to seek immediate medical attention rather than booking a routine appointment.
Hearing Instrument Specialists
Hearing instrument specialists are licensed to sell and fit hearing aids, but their scope is narrower than an audiologist’s. They do not diagnose hearing loss or hearing disorders and are not trained to evaluate or treat tinnitus, auditory processing problems, or other complex auditory conditions. If you already have a diagnosis and simply need help selecting and fitting a hearing aid, a hearing instrument specialist can do that. But if you haven’t been evaluated yet, starting with an audiologist gives you a more complete picture of what’s going on.
Over-the-Counter Hearing Aids
Since 2022, adults 18 and older with perceived mild to moderate hearing loss can buy hearing aids over the counter, in stores or online, without seeing any professional at all. No medical exam, no audiologist appointment, no prescription required. The FDA created this category specifically to make hearing aids more accessible and affordable for people whose loss isn’t severe.
OTC hearing aids won’t be right for everyone. If your hearing loss is more than moderate, if you’re under 18, or if you need a surgically implanted device, you’ll still need a prescription and professional evaluation. And if OTC aids aren’t helping after a few weeks, that’s a signal to get a proper diagnostic workup with an audiologist.
When You Need a Full Team
For advanced hearing loss that doesn’t respond well to hearing aids, a cochlear implant may be an option. The evaluation process involves a multidisciplinary team, typically including a surgeon who specializes in cochlear implants and at least one audiologist with implant experience. Depending on the complexity of your case, the team may also include a rehabilitation therapist, radiologist, psychologist, and social worker. This isn’t something you navigate alone; the team guides you through testing, candidacy determination, surgery, and the months of auditory rehabilitation afterward.
What Medicare and Insurance Cover
Medicare Part B covers diagnostic hearing exams when a doctor orders them to determine whether you need medical treatment. As of recent policy changes, you can also visit an audiologist once every 12 months without a physician’s order, but only for non-acute hearing conditions (like gradual age-related loss) or for diagnostic services related to surgically implanted hearing devices. Private insurance varies widely, so check your plan before booking. The distinction matters: a “diagnostic” hearing test ordered to investigate a medical concern is far more likely to be covered than a “routine” hearing screening.
Choosing the Right Starting Point
Your best first move depends on what’s happening with your ears:
- Gradual hearing loss over months or years: Start with an audiologist for a full evaluation.
- Sudden hearing loss over hours or days: See an ENT or go to an emergency room immediately. The 72-hour treatment window is critical.
- Mild trouble hearing in noisy rooms: You could try OTC hearing aids first, or see an audiologist if you want a diagnosis before spending money.
- Ear pain, drainage, or repeated infections: See an ENT, since these suggest a medical problem that may be treatable.
- A child failing a hearing screening: Go to a pediatric audiologist for a proper diagnostic evaluation.
Many people end up seeing both an audiologist and an ENT at different points. The audiologist identifies what kind of hearing loss you have and how severe it is, and the ENT steps in if there’s a medical cause to address. Starting with one doesn’t lock you out of the other.
