How good am I at detecting audible distortion? I’ll go to Germany to find out.

To ensure a valid test, I wore a pair of IEMs with vanishing low measured distortion. (The 7Hz x Crinacle Zero:2) This was the result from my first pass.
You reached an audibility threshold of -39 dB. This value is near the mean value of the audibility threshold of all listeners participated in the test. However, there were some other participants that were more sensitive in detecting those distortions. It is very likely that those participants had more experience in careful listening. Listeners who have repeated the test see that a little bit of training will improve their sensitivity for those distortions and reduce their audibility threshold.
Some listeners went all the way down to -69 dB! Now that I’m familiar with the test, and there are other parameters that can be selected, including music, I’ll give it another try later.
