Most independent filmmakers, starved for resources, focus every dollar and every ounce of energy entirely on the visual image. Sound is an afterthought, relegated to capturing dialogue and dropping in a cheap score. David Lynch understood early on that true psychological terror is auditory. For his 1977 debut Eraserhead, Lynch partnered with sound designer Alan Splet to pioneer a radically new approach to cinematic audio.
Musique Concrète and the Found Sound
Rejecting traditional orchestral scoring and standard Foley work, Lynch and Splet utilized the techniques of musique concrète. Rather than composing music, they spent 63 days—working nine hours a day—recording “found” everyday noises. They recorded howling wind, electrical hums, and the metallic vibration of guy wires.
Splet then meticulously manipulated these recordings in the studio. He slowed them down, re-pitched them, and layered them into an oppressive, industrial drone. They completely blurred the line between a literal sound effect and a musical score.
The Sound as Character
By constructing a pervasive, low-frequency mechanical rumble that never truly ceases throughout the film’s runtime, they made the soundtrack function as a character itself.
It acts as a physical weight on the audience. It suffocates the viewer in a claustrophobic atmosphere of nihilistic dread that no visual trickery or horrifying prop could ever achieve on its own. Eraserhead proves that if you want to truly disturb an audience, you must bypass their eyes and attack their ears.
Insights regarding the collaboration between David Lynch and Alan Splet, and their use of musique concrète techniques, were synthesized from sound design retrospectives.
