In a word we can see the world with the ears, like some blind people already did, but we will never spoke with the eyes...Even if some particular popular idiom say so....
Hearing is complex more than the eyes and incorporate the visual system not the opposite...Ears are able to retrieve deep hidden information and translate it ...
The eye redistribute SOME of what is already spatially there...Eyes dont create a complete new world like the ears did with what we call MUSIC or SPEECH , two complete new worlds of sound anchored in the human body....
How simplistic will be someone who think we can "measure" hearing creative power, or even only his "audible" resolutive abilities or his interpretative power, with only a decibel meter linear scale to decide what we can hear and what we cannot ?
Any sound is a complex body of potential information not measurable by the Hertz scale sorry....
