Hearing Frequency Test
Explore audible tones using your device. This browser test cannot diagnose hearing loss.
Tone and sweep controls
Use a comfortable listening level. Device speakers, headphones, age, and room noise all affect which tones you can hear.
Both sweeps move linearly through the selected range in equal Hz steps. Mark the highest tone you can hear during the upward sweep, or the lowest during the downward sweep.
Safety: start with your device volume low. High-frequency tones can be uncomfortable or inaudible on some equipment. Stop immediately if you feel discomfort. This is not a medical hearing test.
Tool guide
About Hearing Frequency Range Test
Play a frequency sweep to explore tones your device can produce and that you can notice. This browser activity cannot diagnose hearing loss; speakers, headphones, volume, age, and background noise affect the result.
How to use this tool
- 1Use safe, comfortable volume and choose the upward or downward sweep option.
- 2Start the sweep and mark only the frequencies you can clearly hear during the active run.
- 3Review the recorded range as a rough device-dependent observation, not a clinical measurement.
How the tool works
The page generates tones through the Web Audio API and sweeps linearly across a selected frequency range. The user records the highest or lowest heard point during the matching sweep. Audio hardware and browser output may not reproduce the full range.
Worked real-world example
A phone speaker may not produce a low tone clearly even if a headset could, so the measured lower limit is partly a device result.
Common scenarios and use cases

Important details and limitations
Do not raise volume to force a tone to be audible. This is not a hearing exam; pain, ringing, sudden hearing change, or concern should be discussed with a qualified healthcare professional.
Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.
Frequently asked questions
Can this diagnose hearing loss?
No. It is not calibrated clinical equipment.
Why do headphones change the result?
Different devices reproduce frequency ranges differently.
Should I turn volume very high?
No. Keep the level comfortable and stop if it hurts.
