I've stated this many times, so why not once more...
"I'll defend the person who seeks the truth but
fight the person who claims to have found it."
As @teo_audio points out, the ear does not hear the same way a signal is measured. Get your head around that, and your ass will follow.
The ear "hears" in a non-linear manner as opposed to how a signal is measured. We can draw correlations but there's no absolutes.
All the best,
