passed forward, but so far there is still nothing apart from a mechanical
motion. In other words, there is as yet no sound.
The process whereby these mechanical motions begin to be turned
into sound begins in the area known as the inner ear. In the inner ear is a
spiral-shaped organ filled with a liquid. This organ is called the cochlea.
The last part of the middle ear is the stirrup bone, which is linked to
the cochlea by a membrane. The mechanical vibrations in the middle ear
are sent on to the liquid in the inner ear by this connection.
The vibrations which reach the liquid in the inner ear set up wave
effects in the liquid. The inner walls of the cochlea are lined with small
hair-like structures, called stereocilia, which are affected by this wave
effect. These tiny hairs move strictly in accordance with the motion of the
liquid. If a loud noise is emitted, then more hairs bend in a more powerful
way. Every different frequency in the outside world sets up different
effects in the hairs.
But what is the meaning of this movement of the hairs? What can the
movement of the tiny hairs in the cochlea in the inner ear have to do with
listening to a concert of classical music, recognizing a friend's voice,
hearing the sound of a car, or distinguishing the millions of other kinds of
sounds?
The answer is most interesting, and once more reveals the complexity
of the ear. Each of the tiny hairs covering the inner walls of the cochlea is
actually a mechanism which lies on top of 16,000 hair cells. When these
hairs sense a vibration, they move and push each other, just like dominos.
This motion opens channels in the membranes of the cells lying beneath
the hairs. And this allows the inflow of ions into the cells. When the hairs
move in the opposite direction, these channels close again. Thus, this
constant motion of the hairs causes constant changes in the chemical
balance within the underlying cells, which in turn enables them to
produce electrical signals. These electrical signals are forwarded to the
brain by nerves, and the brain then processes them, turning them into
sound.
Science has not been able to explain all the technical details of this
system. While producing these electrical signals, the cells in the inner ear
also manage to transmit the frequencies, strengths, and rhythms coming
from the outside. This is such a complicated process that science has so far
