Most adults should have a hearing screening at least once every 10 years until age 50, then every 3 years after that. Those are the baseline recommendations from the American Speech-Language-Hearing Association, but several factors can move that schedule up significantly, including your job, medications, and whether you’ve noticed any changes in how well you hear.
The Standard Schedule by Age
For adults between 18 and 50 with no known risk factors, a hearing screening every decade is generally sufficient. After age 50, the interval tightens to every 3 years. This shift reflects the reality of age-related hearing loss, which accelerates in middle age and beyond. About one in three people between 65 and 74 has some degree of hearing loss, and the changes often happen so gradually that you may not notice them yourself.
These are minimums. If you’re exposed to loud noise regularly, take certain medications, or have other risk factors, more frequent testing is appropriate.
When Children Need Testing
Newborns should have their hearing screened before leaving the hospital or within the first month of life. If a screening suggests possible hearing loss, a follow-up evaluation with a pediatric audiologist should happen by 2 to 3 months of age, with any needed intervention starting by 6 months. Early detection matters enormously for speech and language development.
After infancy, children are typically screened at regular intervals during well-child visits and at school. The NIDCD recommends tracking communication milestones through age 5 and speaking with a pediatrician promptly if anything seems off at any age. Children with risk factors for hearing loss, such as a family history or frequent ear infections, may need more frequent monitoring on a schedule set by an audiologist.
Workplace Noise Changes the Rules
If you work in an environment where noise levels reach or exceed 85 decibels over an 8-hour shift (think manufacturing floors, construction sites, or airport tarmacs), federal workplace safety rules require your employer to provide annual hearing tests. Your employer must also establish a baseline audiogram within 6 months of your first exposure at that noise level. Each year’s test is compared against that baseline to catch shifts early.
This isn’t optional. OSHA mandates these annual tests as part of a hearing conservation program, and the results are used to determine whether your hearing protection is working or needs to change. If you work in a noisy trade and haven’t been offered annual testing, that’s a gap worth raising.
Medications That Can Damage Hearing
Certain drugs are known to harm the inner ear, and if you’re taking any of them, the standard testing schedule doesn’t apply. The most significant offenders are platinum-based chemotherapy drugs and a class of antibiotics called aminoglycosides, both of which can cause permanent hearing loss. Other medications, including certain diuretics, antimalarials, and high-dose aspirin-type pain relievers, can cause temporary hearing changes.
During treatment with these drugs, hearing is monitored on a much tighter schedule. Patients on cisplatin, for example, typically have their hearing checked before every treatment session. Those on aminoglycoside antibiotics may be tested weekly or biweekly. After treatment ends, follow-up testing continues: typically within a month of the last dose, then every 3 months for a year.
Risk factors that make ototoxic damage more likely include poor kidney function, low red blood cell counts, taking multiple ear-toxic drugs at the same time, genetic predisposition, and a history of noise exposure. If any of these apply to you, your medical team should be coordinating hearing monitoring into your treatment plan.
Signs You Shouldn’t Wait for a Scheduled Test
Some situations call for immediate evaluation, not your next routine screening. Sudden hearing loss in one ear is a medical emergency. People often discover it when they wake up in the morning or try to use a phone on the affected side. It may be preceded by a loud pop and accompanied by a feeling of fullness in the ear, ringing (tinnitus), or dizziness. Starting treatment quickly, often within the first few days, gives you the best chance of recovery.
Other signs that warrant testing sooner rather than later include frequently asking people to repeat themselves, turning the TV volume higher than others find comfortable, difficulty following conversations in noisy settings, or persistent ringing in your ears. These don’t require an emergency visit, but they do mean you should schedule a hearing evaluation rather than waiting for your next decade or 3-year milestone.
Screening vs. Diagnostic Testing
A hearing screening is a quick pass/fail check. It plays tones across the frequencies used in speech (roughly 500 to 4,000 Hz) at the upper edge of normal hearing, around 25 to 30 decibels for adults and 15 to 20 decibels for children. If you can hear the tones, you pass. If you can’t, you’re referred for further evaluation.
A diagnostic audiogram is more thorough. It determines the softest sound you can hear at each frequency, mapping out the specific pattern and severity of any hearing loss. This takes more time and is performed by an audiologist. If a screening flags a concern, the diagnostic test is the next step, and it’s what gives your provider enough detail to recommend treatment.
Online Hearing Tests as a Starting Point
If you’re curious about your hearing but not ready to book an appointment, validated online hearing tests can serve as a reasonable first screen. A recent validation study found that a self-administered online test detected mild hearing loss with 83% sensitivity and 94% specificity, performing comparably to established clinical screening tools. Its negative predictive value was 97%, meaning that if the test says your hearing is normal, it’s very likely correct.
That said, online tests have limitations. Estimated hearing thresholds can differ from gold-standard audiometry by an average of about 15 decibels depending on the frequency, which is a meaningful margin. They’re useful for flagging a problem that deserves professional follow-up, but they can’t replace a diagnostic evaluation in a sound-controlled booth. Think of them as a nudge, not a diagnosis.
What Insurance Typically Covers
Medicare Part B covers diagnostic hearing and balance exams when ordered by a doctor to determine whether you need medical treatment. The key word is “diagnostic,” meaning there needs to be a medical reason for the test, such as reported hearing difficulty or a condition that affects hearing. Routine screenings without a medical indication are generally not covered under traditional Medicare.
Private insurance varies widely. Many plans cover diagnostic audiometry when referred by a physician but don’t cover routine screening for adults. If cost is a concern, community health fairs, university audiology clinics, and some hearing aid retailers offer free or low-cost screenings that can at least tell you whether a full evaluation is worth pursuing.
