Hearing Range Test (Mosquito Tone Check)
Play high-pitched tones one by one and note which ones you can hear. The tool shows the upper limit of your hearing and a rough age guide. This is not a medical test. To check the speakers or headphones themselves, use the Speaker Test. Sound is generated on this page and nothing is sent anywhere.

Always start with the volume at minimum and raise it slowly. Loud sound can damage your ears, so this tool caps its volume. This is not a medical diagnosis; if you are worried about your hearing, see a doctor.
Test each frequency
Press "Play" from the lowest frequency upward, and tick the box when you hear it. Each tone lasts about 2 seconds.

Result
Nothing is ticked as "Heard it" yet.
This is a rough guide based on general trends, not a medical diagnosis.
Notes
- This is not a medical diagnosis. If you are concerned about your hearing, get a hearing test from a doctor.
- Start at a low volume. The tool caps its own volume to protect your ears, but a high OS or amplifier volume can still be dangerous.
- You may not hear a tone simply because your equipment cannot play it. Built-in laptop and phone speakers often produce almost nothing above 15 kHz, so use headphones if you can.
- Bluetooth compresses audio and can cut high frequencies. A wired connection gives a more reliable result.
- Background noise, your ears, your condition and differences between devices all change the result. The age guide reflects only a general trend.
- Stop the test if you have ringing in the ears, dizziness or trouble hearing.
Glossary
Hearing range
The range of sound frequencies a person can hear, usually quoted as about 20 Hz to 20,000 Hz. High frequencies in particular become harder to hear with age.
Mosquito tone
A high-pitched tone of around 17 kHz that sounds like a mosquito. Younger people tend to hear it and older people tend not to.
Frequency (Hz, kHz)
The pitch of a sound, given as the number of vibrations per second. 1 kHz is 1,000 Hz. A higher number is a higher pitch.
FAQ
I cannot hear the high tones at all. Is my hearing bad?
Not necessarily. High-frequency hearing declines naturally with age, and built-in laptop and phone speakers are poor at high pitches. Try headphones with the volume raised a little, and see a doctor if you are still concerned.
How accurate is the age guide?
It is a rough guide based on the general trend that younger people hear higher pitches. Individual variation is large and it is not a medical diagnosis. Equipment limits and background noise also change the result, so treat it as a bit of fun.
How loud should the volume be?
Start at minimum and raise it slowly until you just begin to hear the tone. The slider here has a cap, but a high OS or amplifier volume can still be dangerous. Never go to a level that is uncomfortable.
How do I know if sound is really playing above 16 kHz?
Your equipment may be unable to produce the tone at all, in which case you are not failing to hear it, it simply is not playing. Trying wired headphones or other equipment helps tell the two apart.
Are my results saved or sent anywhere?
No. The tones are generated on your device and the ticks are only used to show the result in your browser. Nothing is uploaded or stored.
