KSB - Ken Smith said:Not everyone has the same ears or senses. I play two different Basses for someone and they tell me they hear no difference while it is night and day to me.
This is quite interesting in and of itself. Pathology aside, it really is the case that, for practical purposes, we all DO have the same ears. The capabilities of the normal auditory system are astonishingly uniform across a number of fundamental measures. Yes, there are areas where there are inter-individual differences.
Your example is actually quite interesting and important. What is really going on is that you have LEARNED which aspects of the physical waveforms reaching your ears must be attended to in order to hear the difference. You have learned to discriminate. It is not that your ears are different from those who seem not to make the discrimination. They just do not know for what to listen!
One of the skills in psychoacoustics is to design and/or use a procedure that causes the listener to "focus in" on the relevant discrimination quickly.
So, it's a matter of the cortex, not the ears.
