Silence: A Sound Picture (1936)

The film discusses the relationship between musical tones and noise, explaining that both are sounds but differ in their wave patterns. An oscillograph is introduced as a tool to visualize sound waves, showing that musical notes produce regular waves while noise generates irregular waves. The transcript highlights advancements in automobile engineering that have significantly reduced noise levels in modern cars. Engineers have addressed various sound sources, such as engines, brakes, and wind resistance, resulting in a much quieter driving experience compared to older models.
