Questions about hearing.

Things people have asked us. Nothing on this page is selling anything. Just how hearing works, what the numbers mean, and when it's worth seeing someone.

One thing first

This is general information, not medical advice. If something has changed in your hearing, see an audiologist or an ENT. Sudden hearing loss in one ear is treated as urgent.

01

Tinnitus and ringing

What is tinnitus, and what causes it?

Tinnitus is the perception of ringing, buzzing, hissing, or clicking that has no outside source. It often follows noise exposure that overworks the tiny hair cells in the cochlea, your inner ear. When those cells are stressed, the brain's hearing pathways can start generating a phantom tone on their own. Other common contributors include earwax buildup, certain medications, stress, high blood pressure, and jaw or sinus issues.

Does tinnitus go away on its own?

Short-term ringing, like the kind you notice after a loud night out, often settles within a few hours to a couple of days as your auditory system recovers. Ringing that lasts longer than a few months is less likely to disappear completely, but many people find it becomes far less noticeable over time with the right habits and support. If it persists, an audiologist can help.

How long does tinnitus last after a concert?

For most people, post-concert ringing fades within a few hours to about 48 hours. If it hangs around past two days, or comes with muffled hearing, that is worth getting checked. Repeated loud exposure without recovery time or protection raises the chance that ringing sticks around.

Is tinnitus permanent?

It depends on the cause. Ringing from a single loud event is often temporary. Tinnitus tied to long-term, cumulative hearing changes can last much longer. Because human cochlear hair cells do not grow back once they are lost, protecting the hearing you have is the most reliable long-term strategy.

What makes tinnitus worse?

Common aggravators include more loud-noise exposure, poor sleep, and high stress, and for some people a lot of caffeine or alcohol. Certain medications can play a role too. Noticing your own patterns, and reducing the triggers you can control, often makes the biggest day-to-day difference.

Can stress cause tinnitus?

Stress and anxiety are well documented as triggers that can start or amplify the perception of ringing. When you are wound up, the nervous system becomes more reactive, and tinnitus can feel louder. Sleep, movement, and relaxation habits that lower overall stress tend to help.

Can earwax cause tinnitus?

Yes. A buildup of earwax can create temporary ringing, muffled hearing, or a feeling of fullness. This kind usually clears once the wax is safely removed by a professional. Avoid cotton swabs, which tend to push wax deeper.

02

Concerts and noise

Why do my ears ring after a concert?

Loud sound overworks the hair cells in your cochlea. In response, your brain's hearing pathways can generate a phantom tone, which is the ringing you notice afterward. It is a signal that your ears were pushed hard. The louder and longer the exposure, the bigger that signal tends to be.

How long will my ears ring after a concert?

Usually a few hours up to about 48 hours. If the ringing lasts beyond two days, or you also notice muffled hearing in one or both ears, see an audiologist. Giving your ears quiet recovery time right after a show helps.

How do I stop my ears ringing after a concert?

Give your ears real quiet afterward, ideally skipping headphones for the rest of the night and the next day. Sleep well and step away from further loud noise. If the ringing has not eased within about 48 hours, or it comes with reduced hearing, check in with a professional.

Should I wear ear protection at concerts?

Yes. Live shows routinely hit 100 to 110 dB or more, well past the level where prolonged exposure becomes risky. High-fidelity musician earplugs are a great pick because they lower the volume fairly evenly without making the music sound muddy. Even basic foam plugs are far better than nothing.

Is hearing damage from concerts reversible?

Damage from a single show is often temporary and can recover with quiet rest. Damage that builds up from repeated loud exposure is much harder to undo, because cochlear hair cells do not regenerate once they are gone. That is why earplugs, lower volumes and breaks from noise matter so much.

How loud is too loud?

As a reference, sound at or below about 70 dB is generally considered safe for as long as you like. Risk climbs with both volume and time above roughly 85 dB. Safe listening time drops quickly as things get louder, roughly halving for every 3 dB increase, so a 100 dB concert can become risky in around 15 minutes. A simple rule of thumb: if you have to shout to be heard by someone an arm's length away, it is too loud.

  • 85 dB · 8 hours
  • 91 dB · 2 hours
  • 97 dB · 30 min
  • 100 dB · 15 min
What is oxidative stress in the ear?

When the ear handles very loud sound, its hair cells produce a burst of unstable molecules called free radicals. The buildup of these molecules is known as oxidative stress, and it is one of the mechanisms researchers connect to noise-related hearing changes. The body has its own antioxidant defenses that help clear free radicals, which is an active area of hearing research.

03

Hearing loss

Can hearing loss be reversed?

Some kinds can. Conductive hearing loss from earwax, fluid, or infection can often be treated medically. Sensorineural hearing loss, which comes from permanent inner-ear hair cell damage, is not currently reversible, though research into future treatments is ongoing. Protecting the hearing you still have is the most effective tool available today.

What causes hearing loss?

The most common causes for noise-induced hearing loss are aging, repeated noise exposure, ear infections, earwax blockage, some medications, head or ear injury, and genetics. Noise-induced hearing loss is the most preventable type, and it is more prevalent today due to heavy headphone use and loud events.

Is there a link between hearing loss and dementia?

Research has found an association between untreated hearing loss and higher dementia risk. One leading idea is that straining to hear adds cognitive load, and that the social isolation hearing loss can bring may also play a role. Addressing hearing changes early, including with hearing aids when appropriate, is linked to better outcomes. This is an association, not proof that one directly causes the other.

What are the early signs of hearing loss?

Early signs include trouble following speech in noisy places, often asking people to repeat themselves, turning the TV or phone up louder than others prefer, and difficulty with higher-pitched sounds. Struggling with consonants like s, f, and th is a common first hint of noise-related change. A hearing test is the only way to know for sure.

Do headphones or earbuds cause hearing loss?

They can, if you listen loud for long stretches. The World Health Organization estimates that over a billion young people are at risk from unsafe listening. A handy guideline is the 60/60 approach: keep the volume around 60 percent and take regular breaks rather than listening for hours nonstop. Over-ear headphones at a sensible volume tend to be gentler than earbuds pushed loud.
