PASSAGE I: The Invisible Art of Noise
¹ When watching a movie, audiences usually focus on the actors' dialogue or the sweeping musical score. Rarely do they consider the crunch of footsteps in snow, the rustle of a silk dress, or the squeak of a saddle. Most viewers assume these sounds were recorded on set during filming. In reality, however, microphones are designed to pick up dialogue, not background noise. Most of the detailed sounds you hear (1) has been created weeks later in a studio by a specialized craftsperson known as a Foley artist.
² Named after Jack Foley, a sound editor at Universal Studios in the 1920s, the profession requires a unique blend of creativity and athleticism. Foley artists work on specialized stages containing recessed areas called "Foley pits." These pits hold different surfaces—gravel, dirt, hardwood, and more—that mimic real-world textures. To recreate the sound of a character walking, the artist watches the screen and mimics the actor's steps, (2) wearing the shoes that match the character's footwear. If the character is walking on broken glass, the artist steps on scattered ceramic tiles. (3) Having carefully selected the proper materials, the realistic sound is created.
³ The work involves more than just footsteps. Foley artists must be inventive to (4) generate sounds that do not exist in the real world. For a science fiction film, the sound of an alien egg hatching (5) might be created by squishing a honeydew melon. (6) On the other hand, the bone-crunching impact of a fistfight is often simulated by breaking stalks of celery or snapping carrots wrapped in a towel. The goal is realistic audio, even if the source is decidedly artificial.
⁴ Precision is critical. The sound must sync perfectly with the visual action. If a sword is drawn from a sheath one second too late, the illusion is shattered. Foley artists often perform "wild tracks," recording sounds without watching the picture, (7) but for complex scenes, they must perform in real-time, matching their movements to the actor's rhythm.
⁵ Despite their importance, Foley artists often go unrecognized. Their work is successful only when it goes unnoticed. (8) If the audience realizes the sound of a horse's hooves is actually two halves of a coconut shell being banged together, the magic is lost. Like a magician's trick, the art of Foley relies on misdirection.
⁶ Today, digital libraries offer thousands of pre-recorded sound effects. Many directors still prefer the custom touch of a human artist. A canned sound effect is static and repetitive, (9) whereas a Foley performance is organic. It breathes life into the visual image, giving weight and texture to the world on screen. (10) The next time you watch an old horror movie, remember that someone might be standing in a studio, slowly twisting an old rusty hinge.(11)
