sound vibrations by intensifying them, and the inner ear sends
these vibrations to the brain by translating them into electric
signals. Just as with the eye, the act of hearing finalizes in the

center of hearing in the brain.
The situation in the eye is also true for the ear. That is, the
brain is insulated from sound just as it is from light. It does not
let any sound in. Therefore, no matter how noisy is the out-

side, the inside of the brain is completely silent. Nevertheless,
the sharpest sounds are perceived in the brain. In your com-
pletely silent brain, you listen to symphonies, and hear all of

the noises in a crowded place. However, were the sound level
in your brain was measured by a precise device at that mo-
ment, complete silence would be found to be prevailing there.
As is the case with imagery, decades of effort have been

spent in trying to generate and reproduce sound that is faith-
ful to the original. The results of these efforts are sound
recorders, high-fidelity systems, and systems for sensing

sound. Despite all of this technology and the thousands of en-
gineers and experts who have been working on this endeavor,
no sound has yet been obtained that has the same sharpness
and clarity as the sound perceived by the ear. Think of the

highest-quality hi-fi systems produced by the largest company
in the music industry. Even in these devices, when sound is
recorded some of it is lost; or when you turn on a hi-fi you al-

ways hear a hissing sound before the music starts. However,
the sounds that are the products of the human body's technol-
ogy are extremely sharp and clear. A human ear never per-
ceives a sound accompanied by a hissing sound or with

atmospherics as does a hi-fi; rather, it perceives sound exactly
