First: a quick safety check
Sudden hearing loss or a sudden major drop in hearing (hours to days) can be time-sensitive. Seek urgent evaluation—especially if it affects one ear, follows a loud blast or head injury, or comes with new severe dizziness or neurologic symptoms.

This page is the Getting Care companion to our Living Well: Hearing Loss Prevention guide. The Living Well page goes deeper on day-to-day strategies. Here, we focus on the care and planning side: who should be monitored, when to schedule evaluation, and how to reduce risk without guessing.
Three prevention pathways
Choose the section that fits you best. You can also use more than one.
| Pathway | Who it’s for | What “getting care” looks like |
|---|---|---|
| 1) General public | Anyone exposed to loud sound (work, events, tools, headphones) | Know when sound is risky, use protection correctly, consider a baseline hearing test if risk is ongoing |
| 2) Already have hearing loss | Any degree of known hearing loss, hearing aid users, tinnitus with hearing difficulty | Protect remaining hearing, avoid preventable “extra” loss, repeat hearing tests to track change and update care |
| 3) Higher medical / medication risk | Ototoxic medications (some chemotherapy/antibiotics/diuretics), diabetes, vascular risk factors, complex illness | Ask for baseline + monitoring plan, report changes early, coordinate across oncology/primary care/audiology |
1) General public: prevent damage before it accumulates
Know the “risk point” and act early
In the U.S., workplace hearing programs often use 85 dBA as an action level for an 8-hour average exposure. Risk rises as sound gets louder, and one way to remember the math is: with a 3 dB increase, safe time drops fast. For practical decisions, use tools that measure or estimate your exposure (see links below).
Measure your environment when you’re unsure
The NIOSH Sound Level Meter app (iOS) is designed for occupational and everyday noise checks. If you’re regularly around loud sound (events, tools, loud work), measuring helps you choose the right protection.

Choose hearing protection you’ll actually use
- Foam earplugs can provide high reduction when inserted correctly (best for very loud tools and workplaces).
- “Musician” style earplugs can preserve sound quality better for concerts (often easier to tolerate).
- Earmuffs can be easier for short tasks (yard work) and are useful over earplugs for very loud exposure.
If you want a deeper, practical guide (concerts, headphones, and protection choices), go to: Living Well: Hearing Loss Prevention.
Consider a baseline hearing test when risk is ongoing
A baseline test can help you and your clinician detect change over time—especially if you have regular noise exposure, frequent tinnitus after loud events, or work in a high-noise setting.
2) If you already have hearing loss: protecting “what’s left” still matters
Having hearing loss does not make you “immune” to further damage. Additional noise injury can worsen hearing and make hearing devices less effective. Prevention here is about protecting remaining hearing and keeping care updated.
Bring these topics to your next audiology visit
- Noise exposure patterns: work, concerts, power tools, firearms, or frequent loud environments.
- Hearing aid comfort in noise: if sound is uncomfortably loud, you may need programming changes and/or separate hearing protection strategies.
- Tracking change: if speech understanding is declining, don’t assume it’s “just aging”—ask whether testing should be repeated and whether management should change.
Hearing aids are not hearing protection
Hearing aids amplify and shape sound to improve communication. They are not designed to protect your inner ear from hazardous noise exposure. Ask your clinician about a plan for loud environments that fits your hearing profile and comfort.
3) Higher medical / medication risk: ask for a monitoring plan
Some health conditions and some medications can increase risk for hearing change. When risk is elevated, the most “preventive” step is often structured monitoring: a baseline test and follow-up testing at intervals matched to the situation.
If you may receive ototoxic medication
“Ototoxic” means a medication may affect hearing and/or balance. Effects vary by medication and dose; some changes can be temporary, others permanent. Common high-risk categories include some chemotherapy drugs (for example, platinum-based agents), some antibiotics (for example, aminoglycosides), and some diuretics (for example, loop diuretics). Do not stop a medication on your own—bring concerns to your care team.
- Ask before treatment starts: “Do I need a baseline hearing test?”
- Ask during treatment: “What symptoms should I report right away?” (new tinnitus, sudden hearing change, dizziness, sound distortion)
- Ask about follow-up: “When should hearing be rechecked after treatment ends?”

If you have diabetes or vascular risk factors
Hearing health depends on a delicate inner-ear blood supply. Diabetes and cardiovascular risk factors are associated with higher rates of hearing problems, and prevention often overlaps with overall health management (blood sugar, blood pressure, smoking cessation, and medication review). If you have diabetes and notice hearing change, tinnitus, or balance symptoms, bring it up—don’t wait for the next annual visit.

How to decide: routine vs. prompt vs. urgent evaluation
| Situation | Recommended next step | Why it matters |
|---|---|---|
| Sudden hearing loss or sudden major drop (hours to days) | Urgent evaluation (same day if possible). Use EARS Emergency guide. | Some causes are time-sensitive; earlier evaluation can improve options. |
| New one-sided symptoms, new pulsatile tinnitus, or new severe dizziness | Prompt evaluation (days). Use EARS Emergency guide for red flags. | Helps avoid missing conditions that need targeted workup. |
| Gradual change, trouble hearing speech, or suspected long-term noise exposure | Routine audiology visit to test hearing and discuss prevention plan. | Baseline + follow-up testing supports earlier intervention and better planning. |
Bottom line
The bottom line
Prevention is not only about avoiding loud sound—it’s also about timing. Get evaluated urgently for sudden change, build a plan if you have ongoing risk, and ask for monitoring if you’re on treatments that can affect hearing.
