Blind Testing a 11kHz Upper Hearing Limit

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

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	<11kHz

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 11 kHz. Listen to both files: if you think you can hear a difference try the test below, otherwise pick a lower cutoff frequency (change the target value on top of this page).
