What ear age means
Ear age is an educational wellness estimate that relates how high you can still hear certain tones to typical age bands — curiosity-friendly context for your longevity picture, not a clinical hearing test or audiogram.
An ear age test on Carthalis maps your highest comfortable high-frequency threshold to an approximate band for motivation. It is a hearing health age curiosity signal — wellness hearing age context, not medical diagnosis.
Carthalis is a personal health companion: you can try the tone screen on this page, then save results and explore related Twin longevity scores after signup. For clinical hearing concerns, consult an audiologist — this page explains what is ear age in plain language for educational use.
Take the ear age test
Try the calculator on this page — a guided tone screen from 8 kHz toward 22 kHz with headphones. Save your results with a free account to track ear age over time.
Take the 30-second ear-age test
We play a series of high-frequency tones from 8 kHz up to 22 kHz. Mark the highest tone you can hear — we map your threshold to a typical age range.
Your inputs
1. Plug in headphones (any pair). Sit somewhere quiet.
2. Set your device volume to a comfortable mid-level — not loud.
3. Press play. The test sweeps from 8 kHz up. Tap when the tone fades.
We don't store your threshold until you sign up.

How the test works
The Carthalis ear age screen uses Audiogram-based threshold methodology (8–22 kHz sweep) and Frequency-loss to age-band mapping — research-anchored, age-band reference aligned with twin-scores-ear_age — wellness education, not calibrated audiometry.
Find a quiet space
Background noise and phone speakers skew high-frequency tones. Use headphones in a calm room for the most useful ear age test wellness context.
Set comfortable volume
Start at a mid-level volume — loud enough to hear each tone clearly, not loud enough to fatigue your ears.
Run the 8 kHz → 22 kHz sweep
The guided screen plays tones from 8 kHz up toward 22 kHz. Mark the highest frequency you still hear comfortably.
See your approximate band
Carthalis maps your threshold to a typical age band using Audiogram-based threshold methodology and frequency-loss to age-band mapping — an approximate hearing health age estimate, not audiometric certainty.
Results reflect an approximate typical age band for motivation — not audiometric certainty. For clinical hearing concerns, consult an audiologist.
Limits of an at-home check
- Phone or laptop speakers may not reproduce high frequencies accurately — headphones are strongly recommended.
- Room noise, one ear vs both ears, and volume drift can shift results between sessions.
- This wellness hearing age screen is not calibrated clinical audiometry — it cannot detect hearing loss or replace an audiologist.
- For tinnitus, pain, sudden hearing change, or clinical concerns, consult an audiologist or physician.
What to do with your result
Use your approximate ear-age band as motivation — a curiosity-friendly signal in your longevity picture, not a verdict on hearing health.
