Recently, I went on a trip to the Museum of the Moving Image. I saw a great demonstration there on sound editing, and in this blog post, I want to share what I learned.
There are many aspects that make up the sound in a movie, such as the dialogue, sound effects, and musical score. Filmmakers carefully edit together these components in order to convey a specific feeling, to correctly depict action, and to help their movie come to life for the audience. The demonstration at the museum used a clip of the movie Titanic in order to illustrate the complex process of sound editing, so I will use examples from that movie to explain what goes into creating the sound of a film.
Two factors most commonly thought of when discussing sound in film are the dialogue and musical score. However, without the complex arrangement of background noises, the dialogue would seem disjointed and out of place, and with only music, the movie would seem more like a mere moving image and less like an experience. The combination of background noises and surround sound can make a viewer feel like they are in the middle of the action, while the entire soundtrack helps to create an emotional response in the viewer.
Some background noises are taken from a library of sound effects that are public domain, meaning anyone can use them. Examples of this are the lion’s roar, played backwards to create the sounds of the ocean, and the slowed down elephant’s call and gunshot sounds used to depict the noises of the collapsing ship in Titanic. The lion’s roar and gunshots are noises we associate automatically with danger, and the elephant’s sound gives us a sense of the largeness of the ship. Many sounds could successfully imitate the noises of a shipwreck, but the sounds specifically chosen by the makers of Titanic help to make the viewer feel a certain way and subconsciously make connections.
A Foley artist, specifically for a movie, creates other background noises in a studio. In Titanic, one of these sound effects is a tin can being crushed. A sound many people here in everyday life, created with a minimal cost, amplified in a studio, creates a gut-wrenching effect when a large portion of the ship crumbles.
The sound effects in a film have as much of an impact on the audience as the musical score, dialogue, and non-sound aspects of filmmaking. At the Museum of the Moving Image, I learned just how much work goes into carefully choosing and orchestrating sound effects for a movie.
