About this test
The test plays pure tones at eight frequencies, one ear at a time, starting almost silent and rising by 5 dB every step. When you press the button the level is recorded as your threshold for that frequency, and the chart shows both ears side by side. Because the result depends on your headphones, volume and room, it is a relative check, ideal for comparing ears, spotting a weak headphone driver or seeing how high you can hear. It is not a medical hearing test.
How to use this test
- Use headphones in a quiet room and play the 1 kHz reference. Set your system volume so it is clearly audible but comfortable.
- Choose both ears or one side, then press Start.
- Press the button (or Space) as soon as you hear each tone.
- Compare the left and right curves and note the highest frequency you heard.
Frequently asked questions
Is this a medical hearing test?
No. Consumer headphones and browsers are not calibrated. If you notice hearing loss, ringing or a big difference between ears, see a doctor or audiologist.
Why can't I hear 16 kHz?
The upper limit of hearing drops with age: many adults over 30 cannot hear above 15–16 kHz. Some headphones also roll off at high frequencies.
Why is one ear weaker?
It may be your hearing, but often it is the headphones: swap them round and repeat. If the weak side moves, the headphones are the cause.
