Blind Testing a 18 kHz Upper Hearing Limit

Change the target frequency:  10kHz  11  12  13  14  15  16  17  18  19  20kHz


This blind test helps you assess the upper limit of your hearing frequency range. This test is an extension of our High Frequency Response and Hearing Test.

While both tests measure the same limit, the blind test will give you results that are probably closer to your real life listening experience. Instead of generating a pure sine sweep such as in our initial test, we are now using white noise. Noise induces a masking effect: the sound produced in your audible range will now mask the frequencies located at the very edge of your hearing range, reducing your audible frequency range.

Using noise also minimizes the side effects of aliasing (by masking the aliased frequencies as well).

Files being tested

Full Range Below 18kHz

The first one plays back full range white noise, with frequencies extending up to 22 kHz. The second file plays back a low-pass filtered noise, with no sonic content above 18 kHz. Listen to both files: if you think you can hear a difference try the test below, otherwise pick a lower cutoff frequency at the top of this column.

The Test

Full Range Below 18kHz
Listen to [?] then vote — multiple guesses not allowed (your vote triggers a new draw)

To pass a blind test, you will need to perform 10 trials at least, obtain a high score and reach a high confidence level: 95% is standard to rate statistical significance. It means that your score outperforms random guesses by 95%. There is still a probability that you just got lucky though, 5%. To reduce such probability to 1%, keep testing until you reached a confidence level of 99%.

If you didn't pass this test, try with a lower cutoff frequency: 10kHz 11kHz 12kHz 13kHz 14kHz 15kHz 16kHz 17kHz ...

Otherwise, increase the limit: 19kHz 20kHz .
