Purpose
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 121kHz |
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 121 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 121kHz | |
| 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 18kHz 19kHz 20kHz 21kHz 22kHz 23kHz 24kHz 25kHz 26kHz 27kHz 28kHz 29kHz 30kHz 31kHz 32kHz 33kHz 34kHz 35kHz 36kHz 37kHz 38kHz 39kHz 40kHz 41kHz 42kHz 43kHz 44kHz 45kHz 46kHz 47kHz 48kHz 49kHz 50kHz 51kHz 52kHz 53kHz 54kHz 55kHz 56kHz 57kHz 58kHz 59kHz 60kHz 61kHz 62kHz 63kHz 64kHz 65kHz 66kHz 67kHz 68kHz 69kHz 70kHz 71kHz 72kHz 73kHz 74kHz 75kHz 76kHz 77kHz 78kHz 79kHz 80kHz 81kHz 82kHz 83kHz 84kHz 85kHz 86kHz 87kHz 88kHz 89kHz 90kHz 91kHz 92kHz 93kHz 94kHz 95kHz 96kHz 97kHz 98kHz 99kHz 100kHz 101kHz 102kHz 103kHz 104kHz 105kHz 106kHz 107kHz 108kHz 109kHz 110kHz 111kHz 112kHz 113kHz 114kHz 115kHz 116kHz 117kHz 118kHz 119kHz 120kHz ...
Otherwise, increase the limit: .
