How to test your hearing online
- Put on headphones and set a comfortable, moderate volume — never raise it to chase an inaudible tone.
- Explore the tone generator: set any frequency from 20 Hz to 20 kHz, pick a waveform (sine, square, sawtooth, triangle) and choose left ear, right ear or both.
- Run the 10-second sweep across the full audible range and note where the sound disappears for you.
- Take the hearing-age test: confirm each rising tone you can hear and get an estimated hearing age at the end.
This online hearing test and tone generator pairs a precise signal source with a quick, fun self-check. The generator produces laboratory-clean tones at any frequency in the audible range, which makes it just as useful for testing whether your new speakers actually reproduce deep bass, hunting resonant rattles in a car door, or comparing left and right earbuds, as it is for the hearing-age game. Everything is synthesized in real time in your browser — nothing to download, no signup, free. The hearing-age figure is an estimate for curiosity, not a medical diagnosis: hardware, volume and background noise all influence it.
FAQ
Is this online hearing test a medical diagnosis?
No. The hearing-age result is a rough estimate for curiosity and depends heavily on your headphones, volume setting and room. It cannot detect or rule out hearing loss — if you have any concerns about your hearing, see an audiologist for a calibrated clinical test.
What does the highest frequency I can hear mean?
Human hearing tops out around 20 kHz in childhood, and the upper limit naturally drifts down with age — many adults hear up to somewhere between 12 and 17 kHz. The test plays rising tones and uses the highest one you confirm to estimate a typical age range for that limit.
Should I use headphones, and how loud?
Headphones are strongly recommended — laptop speakers often cannot reproduce very low or very high frequencies at all, which skews results. Set a comfortable, moderate volume before you start and never crank the volume to chase a tone you cannot hear.
What else can I do with the tone generator?
Plenty: test whether a subwoofer really reaches 30 Hz, find rattling frequencies in a room or car, check left and right channels separately, tune instruments against a reference tone, or run a full 20 Hz–20 kHz sweep to hear where your audio gear gives up. Sine, square, sawtooth and triangle waveforms are included.
