Explore the Physics of Sound Waves, How Sound Is
to Film Via Recording Devices, Audio Pitch, and More
This series of films explores the wonders of sound and how it is
recorded on a variety of media - like film. They cover the theory
of sound waves and how the science was harnessed into practical
applications. The three films that make up this collection have
a run time of 32 minutes.
Here are the films included in this DVD.
1) Sound Recording and Reproduction (Sound on Film) (1943) - This
film details how sound is record on film. It covers the theory and
the techniques used to get the sound that is picked up by the microphone
onto film ready to be played by a sound projector.
2) The Nature of Sound (1948) - This film explores how sound waves
are generated and transmitted through a variety of media, how sound
waves are compressed and expanded, how it can be reflected and other
features and characteristics of sound waves generated by every day
3) Sound Waves And Their Sources (1933) - A technical film that
makes use of oscilloscopes and animated diagrams to explain how
sound waves are generated and their characteristics.
