In sound design for film, video games, podcasts, or ambient art installations, the principle of “less-is-more” is worth thinking about. Sound designers often discover that the strategic absence of certain sonic details can heighten tension, invite curiosity, and encourage emotional involvement. For instance, consider a horror film. The scariest scenes may not be those that feature detailed, bloodcurdling sound effects of monsters in the foreground, but rather those that allow the mind to conjure horrors that remain mostly unheard or faintly implied. Obviously, if we are commercial artists, we do what the client wants us to do, but in cases where I have some latitude, I often try the less-is-more approach because I know how effective it can be.

The sound design for the film “No Country for Old Men” by Skip Lievsay is a master class in subtlety and only using sounds that are absolutely necessary. Alfred Hitchcock famously said, “There is no terror in the bang, only in the anticipation of it.” Much of that anticipation stems from incomplete information. If a scene includes footsteps echoing in a hallway but the source remains unseen and the sound itself is distant or muffled, the viewer’s imagination rushes in to fill the gap. The result is often far more menacing than if the director had provided a full, high-fidelity recording of a recognizable creature snarling. Our internal fears, shaped by personal memories and cultural myths, can surpass anything an artist can depict in concrete detail.

The phenomenon of imaginative engagement is partly rooted in how our brains function. Neuroscientists have explored how the brain’s mirror neuron system is activated not just by literal perception of events, but also by suggestion and implication. When art leaves room for the viewer or listener to participate, these neural circuits fire in ways similar to firsthand experience. The act of completing an image or inferring a sound can evoke empathy and identification, forging a powerful connection with the artwork and its characters or themes.

While championing the power of omission, it’s also important to recognize that not all forms of ambiguity are created equal. Too much vagueness can result in confusion or frustration rather than intrigue. The key is balance: offering just enough detail to ground the audience, while withholding enough to spark curiosity. In painting, this might mean having a focal point rendered with some clarity, while the peripheral elements remain suggestive. In sound design, the main narrative cues might be present and understandable, but certain layers or background elements remain ambiguous, inviting the imagination to fill in the blanks.

 Effective omission hinges on context and intention. A meticulously structured piece can carefully carve out negative space, ensuring that the “missing” details serve the story or emotional arc. Artists must make deliberate choices about what to show and what to hide. This intentional selectivity transforms the artwork from a mere display of skill into a dialogue with the audience.

Leaving out certain details in a piece of sound design can indeed trigger the audience’s imagination in profound ways. By resisting the urge to depict every nuance or audible cue, artists tap into a universal human inclination to seek meaning and resolve mysteries. Painters who leave elements obscured encourage viewers to project their own emotions and narratives onto the canvas, forging a personal connection that a more literal painting might not achieve. Sound designers who omit certain sonic details invite listeners to become co-creators, layering individual memories and imaginations onto the incomplete soundscape.

In a world saturated with high-definition images, immersive audio and constant stimulation, the subtlety of suggestion becomes all the more valuable. It offers a vital counterbalance—a space for quiet wonder and personal storytelling. Ultimately, the choice to omit details is not about negligence or laziness. It can be a deliberate artistic strategy that harnesses the creative power of the human mind, reminding us that some of the most enchanting and memorable experiences in art occur when we are invited to do a bit of the creating ourselves.
