physiology and psychology of hearing


That is my interpretation of the video, but he named it:

Do we all hear the same?

The answer is no, we knew that, but some interesting conditions mentioned explaining why in this video from a recording engineer. 

Congenital amusia, or tone deafness, the inability to determine if one note is higher than the other, affects 4% of the population; that is 1 in every 25 people- wow. 

And yet they may still own a high-end kit.

I sang in choirs for many years, learned at a very young age I had pitch perfect capability. Question is would I have made different choices for a high end system devoid  this capability?  I'd also posit mental clarity or the ability to focus, clear the mind of distractions is a great variable.

Probably explains why a system sounds like heaven to one listener but awful to another.
