Hearing age: what's normal at every age?
Hearing age is the age whose typical hearing most closely matches yours. If the quietest high-pitched sounds you can hear are the ones a typical 60-year-old can hear, your hearing age is 60, whatever your birth certificate says. It turns an audiogram full of decibels into one number anyone can understand.
How much hearing loss is normal at each age
Almost everyone's hearing declines with age, fastest at high frequencies. The process is called presbycusis, and it's so predictable that an international standard, ISO 7029, describes the typical thresholds at every age. The table below shows roughly how much high-frequency loss (around 2–4 kHz, where speech consonants live) is the population median at each decade:
| Age | Typical high-frequency loss | What it feels like |
|---|---|---|
| 20 | 0–3 dB | Nothing (reference hearing) |
| 30 | ~3 dB | No noticeable change |
| 40 | ~8 dB | Rarely noticed in daily life |
| 50 | ~16 dB | Occasional "what?" in noisy rooms |
| 60 | ~27 dB | TV creeping louder; groups harder |
| 70 | ~42 dB | Voices clear but words blur; masks & mumbling defeat you |
| 80 | ~60 dB | Conversation is work without help |
Two caveats worth respecting: individual variation at every age is large (these are medians, not targets), and men typically lose high-frequency hearing somewhat faster than women.
Why is my hearing age older than my real age?
The usual suspects, roughly in order of how often they matter:
- Noise exposure. Decades of loud workplaces, power tools, gigs, and headphones add damage on top of the age curve. This is the biggest controllable factor.
- Genetics. Presbycusis runs in families.
- Health factors. Smoking, diabetes and cardiovascular disease are all associated with faster hearing decline.
- Ototoxic medication. Some antibiotics, chemotherapy drugs and high-dose aspirin can damage hearing.
- Temporary causes. Earwax, a cold, an ear infection, or simply testing in a noisy room can make one result read older than reality. Retest on a quiet day before drawing conclusions.
What to do with the number
A hearing age near your real age: you're typical, so retest every 6–12 months and protect what you have. A hearing age well ahead of your real age is a nudge, not a diagnosis: it's worth a proper evaluation, especially if one ear is worse, and in the meantime amplification tuned to your loss can make conversations and TV comfortable again. And if your hearing age is younger than your years, enjoy the bragging rights and keep the earplugs handy at concerts.

What is a normal hearing age?
A hearing age close to your real age. Hearing declines gradually in almost everyone, so a 60-year-old with a hearing age of 60 has typical hearing for their age.
Why is my hearing age older than my real age?
Most often cumulative noise exposure, then genetics, smoking, diabetes, and certain medications. One-off older readings can be caused by wax, congestion or a noisy room, so retest before concluding anything.
Can hearing age get younger?
Permanent loss doesn't reverse because hair cells in the inner ear don't regrow. Temporary causes are fixable, and protecting your ears stops the gap widening.
