Unformatted sample text from the term paper:
as far back as the Middle Ages and possibly even further, the first successful incident of recorded sound is credited to Thomas Edison. Edisons work, however, rested on the
inroads made by previous experimenters. Edisons success, in turn, forms the basis of sound recording even today. While enthusiastic experimenters like Giovanni
Battista della Porta of the sixteenth century had the unrealistic goal of capturing sound by speaking into metal tubes and quickly slapping on a lid so that the sound would
be "trapped", other experimenters actually made some headway in the recording of sound. Jean Duhamel, for example, had an in-depth understanding of the way sound was created.
Duhamel recognized that sound was caused by airwaves and he attempted to route those airwaves through an elastic membrane and to transfer them
into a hard format with a needle that was attached to the membrane on one end and that rested on an easily-scratched material on the other end. Duhamel hoped
that the movement of the needle would translate the airwaves to the material and that the sound could subsequently be played back by reversing the process.
As it turned out Duhamel was on the right track to recording sound. Although he was unsuccessful, his work and the work of numerous other experimenters
all helped pave Edisons way to making the first successful sound recording, a task Edison accomplished in 1877 using a foil-covered cylinder for his recording material. This devise was
dubbed the phonograph. As the cylinder of the phonograph rotated the sound that passed through a sound collector funnel and that was translated to a membrane and then to
