I don't think it's so much the ear itself, but the way the brain will process a sound.
The devil is in the details?
The ear contains many parts: the ear/canal, "drum", "hammer", "anvil",
"stirrups" (which moves the fluid in the), cochlear, auditory nerves, and
the brain.
The cochlear could be thought of a carpet rolled up into a spiral, and on the
"carpet", contains many "fibers", each "fiber" representing a "tuned fork", each
"fiber" is tuned for a specific incoming wavelength from high to low frequency,
each "fiber" is tied to a specific nerve, and all nerves are "bundled up" and
connected to the brain pathways.
Any problems found along the various parts of the ear; from the ear/canal
to the brain can cause impairments of "hearing" but the brain has to process
what was heard into by "adaptive understanding" and may require the support
of other "sensors" in order to complete "understanding" of speech/frequency.
The "tuning forks" can be thought of that of a bandpass filter - they
can have different or missing "settings".
As I understood it, not all humans have "perfect" hearing and most do not.
As for transducing digital sound, it is not a perfect analog reproduction
of sound due to many factors, the primary being, the speaker/transducer,
the secondary due to processing/sampling/range/filtering, or so I think.
FWIW,
