Interesting article on the sensitivity of human hearing.
Human hearing beats the Fourier uncertainty principle
A bit related....
During the voicing of components, I participated on a panel that consistently and repeatedly identified changes in frequency response of otherwise identical components by as small as 3 millibels. Subsequent testing with others revealed the human ability to identify smaller changes. This is A/B testing switching back and forth between components.
I think there is a discussion of these specific tests (without naming the participants) on the Herron Audio web site.
