Sound film

Sound film is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sound film rather than just read about it. In short: A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures became commercially practical.

Key takeaways

  • Sound film belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sound film to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sound film from memory before moving on to harder problems.

Reference excerpt

A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures became commercially practical. Reliable synchronization was difficult to achieve with the early sound-on-disc systems, and amplification and recording quality were also inadequate. Innovations in sound-on-film led to the first commercial screening of short motion pictures using the technology, which took place in 1923. Before sound-on-film technology became viable, soundtracks for films were commonly played live with organs or pianos. The primary steps in the commercialization of sound cinema were taken in the mid-to-late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie (although it had only limited sound sequences) was The Jazz Singer, which premiered on October 6, 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures. By the early 1930s, the talkies were a global phenomenon. In the United States, they helped secure Hollywood's position as one of the world's most powerful cultural/commercial centers of influence (see Cinema of the United States). In Europe (and, to a lesser degree, elsewhere), the new development was treated with suspicion by many filmmakers and critics, who worried that a focus on dialogue would subvert the unique aesthetic virtues of silent cinema. In Japan, where the popular film tradition integrated silent movie and live vocal performance (benshi), talking pictures were slow to take root. Conversely, in India, sound was the transformative element that led to the rapid expansion of the nation's film industry.

Early history

The idea of combining motion pictures with recorded sound is nearly as old as the concept of cinema itself. On February 27, 1888, a couple of days after photographic pioneer Eadweard Muybridge gave a lecture not far from the laboratory of Thomas Edison, the two inventors met privately. Muybridge later claimed that on this occasion, six years before the first commercial motion picture exhibition, he proposed a scheme for sound cinema that would combine his image-casting zoopraxiscope with Edison's recorded-sound technology. No agreement was reached, but within a year Edison commissioned the development of the Kinetoscope, essentially a "peep-show" system, as a visual complement to his cylinder phonograph. The two devices were brought together as the Kinetophone in 1895, but individual, cabinet viewing of motion pictures was soon to be outmoded by successes in film projection. In 1899, a projected sound-film system known as Cinemacrophonograph or Phonorama, based primarily on the work of Swiss-born inventor François Dussaud, was exhibited in Paris; similar to the Kinetophone, the system required individual use of earphones. An improved cylinder-based system, Phono-Cinéma-Théâtre, was developed by Clément-Maurice Gratioulet and Henri Lioret of France, allowing short films of theater, opera, and ballet excerpts to be presented at the Paris Exposition in 1900. These appear to be the first publicly exhibited films with projection of both image and recorded sound. Phonorama and yet another sound-film system—Théâtroscope—were also presented at the Exposition. Three major problems persisted, leading to motion pictures and sound recording largely taking separate paths for a generation. The primary issue was synchronization: pictures and sound were recorded and played back by separate devices, which were difficult to start and maintain in tandem. Sufficient playback volume was also hard to achieve. While motion picture projectors soon allowed film to be shown to large theater audiences, audio technology before the development of electric amplification could not project satisfactorily to fill large spaces. Finally, there was the challenge of recording fidelity. The primitive systems of the era produced sound of very low quality unless the performers were stationed directly in front of the cumbersome recording devices (acoustical horns, for the most part), imposing severe limits on the sort of films that could be created with live-recorded sound.

Worked examples

Example 1 — a first encounter with Sound film

Start with the simplest possible case. Write down what Sound film claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sound film before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sound film ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sound film

In research
Sound film appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sound film in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sound film is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audiovisual introductions in 1900, Exposition Universelle (1900), Film and video technology, so understanding it makes those chapters shorter.
In everyday life
Look for Sound film outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
