hearing frequency test
Put on headphones, find a quiet place and press Start. The test checks the volume with a 1 kHz tone and climbs through 10 frequencies, from 8 to 20 kHz, until you miss one. It is a curiosity, not a diagnosis.
Two correct answers in a row, each a 50% chance.
So guessing alone rarely gets past 12 kHz.
From 8 to 20 kHz.
Two intervals and the pause between them.
A period of 50 microseconds.
It plays pure tones at 1 kHz (check) and then 8 to 20 kHz in one ear at a time. Each trial has two intervals of about one second, with three short tone pulses in only one of them, chosen at random. You answer in which one you heard the tone. Two correct answers unlock the next frequency; a wrong answer or an "I heard nothing" ends that ear, and the last frequency you got right becomes the result.
Yes, ordinary headphones that cover or rest on the ear, because the test measures each ear separately and speakers mix the sides. Avoid in-canal earphones at a high volume and stay in a quiet place, since room noise hides the highs.
To set the volume once, clearly and comfortably, and confirm the sound comes out of the right ear. If the 1 kHz tone is not heard, the result for the highs would have no meaning.
No. It does not replace an audiogram, measures no decibels and depends on your device. Sudden hearing loss, new or persistent ringing, dizziness and ear pain are reasons to see a doctor, not to repeat online tests.
