How accurate is a browser hearing-range test?
Accurate enough to estimate your audible ceiling within one or two kilohertz, but it is not a clinical audiogram. Real audiometry uses calibrated headphones in a soundproof booth and measures threshold at fixed frequencies (250 Hz to 8 kHz typically) in 5 dB steps. This tool gives you a relative result: 'the highest pure tone you can perceive on this device at this volume.' Use it as a screening trend — if your ceiling drops sharply over months, see an audiologist. For tinnitus matching, use https://devicecheckonline.com/audio/tone.
What is the normal hearing range by age?
A healthy newborn hears 20 Hz to 20 kHz. By age 20, the upper ceiling has usually dropped to 17–18 kHz. Common age bands: 30s reach 14–17 kHz, 40s reach 13–15 kHz, 50s reach 12–14 kHz, 60s reach 10–12 kHz, 70+ commonly under 10 kHz. The low end stays fairly stable through life — high-frequency loss is the dominant pattern. Heavy noise exposure, ototoxic drugs, and genetics can age your hearing decades early; classical musicians and aviation workers often retain better high-end than office workers.
Why do my left and right ears stop at different frequencies?
Asymmetric high-frequency loss is common and usually benign — earwax, a recent cold, side-sleeping habits, or a single loud event (concert speaker, gunshot, airbag) on one side can shift the ceiling by 1–3 kHz. Persistent and significant asymmetry (more than 15 dB across multiple frequencies in a clinical test) can indicate an acoustic neuroma or unilateral hearing loss and warrants medical review. Try the test in both ears separately by using https://devicecheckonline.com/audio/stereo to isolate each side.
I cannot hear anything above 10 kHz — should I worry?
It depends on age. Under 30, that is a red flag for noise-induced hearing loss and worth a clinical audiogram. Over 50, it is firmly within the expected band and rarely needs intervention beyond protecting what remains. Steps that help at any age: wear hearing protection at concerts and when using power tools, keep headphone volume under 60 percent for under 60 minutes a day (the WHO 60/60 rule), and avoid ototoxic medications when possible. Hearing loss above 8 kHz mainly affects clarity of consonants in noisy rooms.
Why does the test use headphones instead of speakers?
Most consumer speakers — laptop, TV, even bookshelf — roll off above 16–18 kHz because the tweeters cannot reproduce ultrasonic content efficiently. If you take this test on speakers, you are measuring your speakers, not your ears. Over-ear headphones with a known response above 18 kHz (most decent models from Sony, Sennheiser, AKG, Beyerdynamic) give an honest test. In-ear monitors work too.

Does volume affect where I hear the tone disappear?
Yes. A tone at threshold may be inaudible at low volume but clearly audible at high volume — that is just the dB difference, not a hearing change. For consistent results, set volume so a 1 kHz tone is comfortably loud (around 60–70 dB SPL), then leave it alone and sweep the frequency. Do not crank volume to chase a 19 kHz tone — sustained high-frequency exposure at high SPL damages exactly the hair cells you are testing. Repeat the test the same way each time to track changes.
