Hearing varies from person to person as much as intelligence and mental orientation and conditioning.
Smart in one way does not specifically relate back to smart ears. Cognitive capacity in the mind can also express itself in cognitive capacity of hearing in ears and mind as a pair. This cognitive variance in speed and precision (as a pair) from person to person (Human IQ of 100 vs 200)... can be as high as a million to one. It’s a non-linear equation.
This definitely DOES encompass human HEARING function as it is a ear/brain function, tied to neural functionality and interconnectedness, tied to it as much as vision, motor drive, intelligence, and so on.
To clarify.. what is that ratio? It is: every increase in 5 ’IQ’ points is roughly equivalent to a required rumination time to reach a functional conclusion with said problem..this requisite time ---is halved. Roughly, and overall, in humanity. Each 5 iq points higher - half the time to figure a thing out.
Thus, the average person, IQ 100, working on a problem, may take lets say..114 years of 24/7 work to reach a satisfactory conclusion in a given problem scenario. the 200 IQ person can reach successful conclusion with the same problem, in one hour. All things being equal, which they are not.
Then comes hearing function, which is wholly integrated with this neural system, and thus suffers similar (not exact but similar) ratios and considerations.
You might have a person who in this lifetime will never hear a given thing.... when someone with really good and well trained ears and connected neural function....might hear it in 30 seconds or less.
No mystery.
Thankfully the brain is plastic so ignorance is a matter of will, in some ways, and it is not truly a native state.
Unless one forces it.
Audiophile, fix thyself.
