being affected by the speaker’s speed, tone or accent. We are generally
completely unaware of this amazing analytical system inside our heads.
The ear’s complex design has frequently been the subject of praise from
scientists.
Of all the organs of the body, few can accomplish as much in so lit-
tle a space as the ear. If an engineer could duplicate its functions, he
would have to compress into approximately one cubic inch a sound sys-
tem that includes an impedance matcher, a wide range mechanical ana-
lyzer, a mobile relay and amplification unit, a multi channel transducer
to convert mechanical energy to electrical energy, a system to maintain
a delicate hydraulic balance and an internal two-way communication
system. Even if he could perform this miracle of miniaturization, he
would be unable to match the ear’s performance. It can set itself to hear
the low throb of a foghorn at one end of its range and the piercing wail
of a jet engine at the other end. It can make the fine distinction between
the music played by the violin and the viola sections of a symphony or-
chestra. ... Even during sleep the ear functions with incredible efficiency.
Because the brain can interpret and select signals passed to it by the ear,
a man can sleep soundly through noisy traffic and the blaring of a neigh-
bor’s television set and then awaken promptly at the gentle urging of a
chime alarm clock. 84
The ear also performs selective perception. Consider what happens
when you hear the sound of a child crying at night. The sound is sent to
the relevant region of the brain and gradually deciphered there. What
kind of sound it is, and whom it belongs to is determined. Since you
have a long-term memory, this sound seems familiar and you realize
that it belongs to one of your children. With this information your brain
now knows that your child wants help, and carries out preparatory mea-
sures such as the release of adrenaline in order to set your body in mo-
tion. All this encourages you to head directly for your child’s bed. In ad-
dition, your memory tells you where your child’s bed is. This perception
and chain of events, here described in very simple terms, actually in-
volve miraculous biochemical and bio-electrical processes, taking place
