The way we perceive sound is
more direct and immediate that
is the case with any other of
our senses. Differing frequencies
of sound waves penetrate
the inner ear (cochlea) and
are deciphered in the nerve
cords of the brain. In the
context of the evolutionary
process it represents one of
the most complex instances
of learning that the human
species has ever undergone.
While the ear is able to perceive
10 octaves, the eye is
only capable of comprehending
the components of one. Since
the eye has the possibility of
scanning a piece of information
many times over, unlike
the ear, it can afford a greater
degree of inexactness.
