The wonders of sound are brought to life in two educational sound waves history films. Follow Jimmy as he goes on a journey to visit a college and learn about sound and their sources in The Nature of Sound. This DVD offers a wonderfully easy to follow look at sound theory in the 1930s & 1940s.
Included Films:
Sound Waves and Their Sources
Sound Waves and Their Sources
Produced: 1933
Length: 9 Minutes
This educational video produced by Encyclopedia Britannica explains the science of sound. The physics of sound effects are made easy to understand. There are three basic sources of sound: vibrating columns of air, vibrating surfaces, and vibrating strings. Many examples are given of how sound is produced, such as how each musical instrument, even when playing the same note, creates different tones because of the way the sound is made. This creates the unique sound an orchestra makes when playing a symphony. Answering the question How does sound travel? is not easy to do in a science video made to be understood by all, but this film uses tuning forks, oscilloscopes, and basic animation to make science sound waves easy to understand.
The Nature of Sound
The Nature of Sound
Produced: 1948
Length: 11 Minutes
A cute kids science video! The elusive and fascinating Nature of Sound is quaintly and cleverly illuminated in this vintage film. When adorable little Jimmy becomes curious about the vibrations caused by a moving train, he goes and gets the scoop on sound from his cousin Phil Hanson. Together they explore science with a folksy charm and good nature that is largely missing from educational movies today. The Nature of Sound is an excellent physics primer on a subject that is understandable and engaging for any child.
