Hearing Test
Check your hearing range in the browser with pure tones from 125 Hz to 12 kHz. Test the left ear, right ear or both, tap when you hear each tone, and see your audible range on a chart. Runs entirely locally — entertainment only, not a medical diagnosis.
Is this hearing test a medical diagnosis?
No. This tool is an entertainment and self-reference toy built on ordinary browser audio. It does not measure hearing loss in any clinically valid way, is not calibrated to professional equipment, and cannot detect or diagnose hearing problems, ear diseases or auditory neuropathy. If you have any concern about your hearing, see an audiologist or ENT doctor for a proper audiometric exam.
How does the test work?
The tool plays short pure sine tones one by one from 125 Hz up to 12 kHz, spaced about a third of an octave apart on a logarithmic scale. Each tone lasts up to about two seconds; when you press the I can hear it button, that frequency is marked as audible. At the end you get the list of frequencies you detected and a chart of your hearing range.
Why should I use headphones?
Laptop and phone speakers roll off steeply below about 200 Hz and above 10 kHz, so they hide the very frequencies this test explores. Headphones — ideally over-ear ones in a quiet room — reproduce the full range and also let you test each ear separately, which speakers cannot do reliably.
How loud should I set the volume?
Set a comfortable moderate level — loud enough to hear the lowest tones clearly but never uncomfortably loud. The test offers low, medium and high output levels. Never crank the volume to hunt for the top frequencies; loud listening can itself damage hearing, and a quieter, longer session is far safer.
What is a normal hearing range?
Healthy young adults typically hear from about 20 Hz to 20 kHz, but sensitivity above 15 kHz fades quickly with age, background noise and everyday exposure. Within this test's 125 Hz to 12 kHz span, hearing everything through roughly 8-10 kHz is common for adults, and losing the very top happens gradually over decades.
Why can't I hear the highest tones?
The most common reasons are age-related high-frequency loss (presbycusis), listening at high volume over the years, earwax or an infection, and simply the limits of your headphones or audio driver. Many adults stop detecting tones above 12-15 kHz. A one-time miss of the top tones is normal and is not, by itself, evidence of hearing damage.
What does a difference between my ears mean?
Small differences are common. If one ear consistently misses frequencies the other clearly hears, that asymmetry is worth mentioning to a doctor, because one-sided hearing changes deserve a professional check. This test is only a rough screening aid and cannot tell you why a difference exists.
Are my results stored or shared?
The test runs entirely in your browser using the Web Audio API: the tones are generated on your device, and your marked frequencies exist only on the page. Nothing is uploaded to any server, and closing or reloading the page clears the results.
How to Use Hearing Test
This browser-based test plays pure tones from 125 Hz up to 12 kHz on a logarithmic scale and records which ones you can hear. Choose left ear, right ear or both, put on headphones, set a moderate volume and tap the button whenever a tone becomes audible. You end up with the list of frequencies you detected and a chart of your approximate audible range. It is an entertainment and reference tool only — not a medical diagnosis.
- Put on headphones and pick a quiet room; laptop and phone speakers cannot reproduce the low and high ends.
- Choose the ear to test (left, right or both) and a volume level — Low, Medium or High. Start with Medium.
- Press Start test: a tone appears, starting at 125 Hz and climbing toward 12 kHz, each held for up to two seconds.
- Tap I can hear it the moment you notice the tone; if you hear nothing before it fades, just wait — the test moves to the next frequency automatically.
- When all frequencies have played, the results show your approximate audible range, the count of heard frequencies and a chart marking heard (dots) and unheard (crosses) tones.
Start at Medium volume and never increase it just to catch the highest tones — loud listening harms hearing itself. Results differ between ears and sessions; consistent one-sided differences are worth mentioning to a doctor. This is not a medical diagnosis.
