Find the highest frequency you can hear, estimate your hearing age, or run a continuous 20 Hz to 20 kHz frequency sweep.
Put on headphones, set a comfortable volume, and take a quick test. You will hear a series of tones; tell us whether you can hear each one.
Use headphones for the most accurate resultsA hearing frequency test checks the highest pitch you can detect with your current headphones, device, volume, and listening environment. The guided mode plays a sequence of high-frequency tones, while Frequency Sweep moves continuously through the wider audible range.
The optional hearing age estimate is based only on the highest reported frequency. It is an educational approximation, not a measure of overall hearing ability or a medical result.
Respond to tones from 17.5 kHz down to 8 kHz and identify the highest frequency you report hearing.
See a broad age estimate derived from the detected high-frequency limit, with clear accuracy limitations.
Run a rising or falling logarithmic sweep and mark the point where the tone becomes inaudible.
Every test tone is synthesized locally with the Web Audio API.
Keep the playback level unchanged after the calibration step.
Use capable headphones and close other audio before beginning the high-frequency test.
Set the device volume so the reference tone is comfortable, clear, and never loud.
Answer each high-frequency tone, or mark the exact point where a continuous sweep disappears.
Repeat with the same setup and treat the frequency and age result as an estimate affected by the entire playback chain.
The test is useful for education and repeatable comparisons under the same setup.
Find the highest tone that remains audible with the current headphones and volume.
Use the same device, headphones, room, and volume when comparing results over time.
Determine whether headphones or speakers reproduce very high tones without obvious buzzes or artifacts.
Use the sweep to hear how perceived pitch changes across the audible spectrum.
Choose the mode according to the result you want.
| Guided high-frequency test | Frequency sweep | |
|---|---|---|
| Range | 8 kHz to 17.5 kHz | 20 Hz to 20 kHz |
| Interaction | Heard or not heard for each step | Mark one point during a continuous sweep |
| Result | Highest heard frequency and age estimate | Marked cutoff frequency |
| Best for | Simple repeatable check | Exploring the wider playback range |
High-frequency output varies substantially between headphones and devices. A missing tone may reflect the equipment rather than the listener.
It plays tones at different frequencies to estimate the range you can detect with the current playback setup.
The commonly cited range is approximately 20 Hz to 20 kHz, although the upper limit varies and often declines with age and noise exposure.
No. It is a broad estimate based only on the highest reported frequency and is strongly affected by headphones, volume, and room noise.
A device or headphone may create a transient click when a tone starts even when it cannot reproduce the intended high frequency accurately.
They can play the test, but built-in speakers often have limited or uneven response. Headphones are recommended.
No. Keep the calibrated level fixed. Raising the volume during the test makes results inconsistent and may be uncomfortable.
No. It is an educational frequency check and cannot replace calibrated audiometry or professional advice.
It focuses on the upper part of the audible range, where age, noise exposure, playback hardware, and volume can strongly affect whether a tone is detected.
This page estimates the highest audible frequency and explores a 20 Hz to 20 kHz sweep. The Online Hearing Test checks separate left and right responses at six practical frequencies.
Headphones and device outputs do not reproduce every frequency equally. Very high or low tones may disappear because of the playback chain rather than your hearing.
