Exploring the Impact of Diegetic and Non-Diegetic Sounds in Video

The distinction between diegetic and non-diegetic sounds plays a pivotal role in crafting a narrative that resonates with audiences. This exploration delves into all of diegesis, offering a comprehensive understanding of their definitions, roles, and creative applications in storytelling. 

Through practical advice and illustrative examples, this guide aims to equip filmmakers and content creators with the knowledge to effectively utilise both diegetic and non-diegetic sounds, enhancing their projects' realism, emotional depth, and immersive quality.

Defining Diegetic and Non-Diegetic Sounds

Understanding the distinction between diegetic and non-diegetic sounds is crucial for filmmakers and video creators looking to maximise the potential of sound design in their stories.

Understanding Diegetic Sounds

Diegetic sounds are intrinsic to the narrative world, encompassing all sounds that characters within the story can hear. Whether it's the chatter in a crowded room, the jingle of keys, or the subtle movements of characters interacting with their surroundings, these sounds are pivotal for constructing a believable environment. 

A memorable instance is found in Amélie, where the protagonist's simple yet profound interactions with her environment are accentuated by the diegetic sounds of skipping stones over water, highlighting the tactile joy of her experiences.

Examples of Diegetic Sounds:

• Dialogues and Conversations: The verbal exchanges between characters.
• Natural Sounds: Wind, rain, thunder, and other environmental sounds that characters are exposed to.
• Source Music: Music originating from instruments, radios, or other devices in the scene.

Uses of Diegetic Sounds in Popular Films:

"Pulp Fiction" (1994) - Dance Scene Music

In Quentin Tarantino's Pulp Fiction, the diegetic sound of the music playing in Jack Rabbit Slim’s dance contest scene, where Mia Wallace and Vincent Vega twist to Chuck Berry's "You Never Can Tell," immerses the audience in the characters' experience, making the scene iconic and vibrantly alive.

"Saving Private Ryan" (1998) - Normandy Landing

The clip below contains scenes of intense violence.

The sounds of the ocean waves, machine-gun fire, explosions, and soldiers' shouts during the Normandy landing sequence are all diegetic. These sounds place the audience right in the middle of the harrowing action, enhancing the realism and immediacy of the scene.

Diegetic sounds serve not only to anchor the audience in the story’s setting but also to enhance the authenticity of the characters’ experiences, making the narrative more relatable and engaging.

Understanding Non-Diegetic Sounds

Non-diegetic sounds are external to the story world. They are employed to influence the audience's emotional response or to convey information indirectly. These sounds are not heard by the characters but are crucial for setting the tone, building suspense, or providing narrative commentary.

A compelling use of non-diegetic sound can be seen in Inception, where Hans Zimmer's powerful score manipulates time and tension, guiding the audience's emotional journey through the complex layers of dreams within dreams. The score amplifies the stakes and depth of the narrative, enriching the viewer's experience beyond the visual spectacle.

Examples of Non-Diegetic Sounds:

• Background Score: Music that sets the mood or underscores emotional shifts in the narrative.
• Narrative Commentary: Voiceovers that provide context, background information, or a character’s thoughts.
• Sound Effects: Added effects like echoes or stylised noises that heighten the drama or significance of a scene.

Uses of Non-Diegetic Sounds in Popular Films:

"Star Wars" (1977) - The Opening Crawl Theme

The iconic opening crawl music in Star Wars, composed by John Williams, is non-diegetic. This triumphant theme sets the tone for the epic adventure that unfolds, immediately drawing the audience into the galaxy far, far away without being heard by the characters.

"The Shawshank Redemption" (1994) - Red’s Narration

Morgan Freeman's character, Red, provides non-diegetic voiceover narration throughout the film. His insights offer the audience a deeper understanding of the characters and the story, enriching the narrative without being part of the character interactions within the prison.

"The Godfather" (1972) - Non-present sound effects

In the pivotal scene where Michael Corleone commits his first act of violence, the non-diegetic sound of a screeching subway train intensifies the tension. This sound effect is not heard by the characters but significantly amplifies the scene's emotional impact for the audience, symbolising Michael's irreversible descent into the criminal underworld.

Incorporating non-diegetic sounds thoughtfully can transform a scene from simply being watched to being profoundly felt, elevating the storytelling to new heights. Through the strategic use of both diegetic and non-diegetic sounds, creators can craft immersive, emotionally resonant narratives that captivate and engage audiences.

Creative Uses in Storytelling

The strategic application of diegetic and non-diegetic sounds significantly shapes the viewer's emotional and perceptual journey, serving as powerful tools in the storyteller's arsenal.

Enhancing Realism with Diegetic Sounds

Diegetic sounds are essential for crafting your video's immersive, authentic world. They anchor the narrative in a tangible reality, enriching the viewer's sensory experience and connection to the story.

• Ambient Environments: The subtle layering of ambient sounds, like birds chirping in a serene forest or the distant hum of city traffic, adds depth and dimension to the scene.
• Contextual Actions: Sounds tied to specific actions, such as the clatter of dishes in a kitchen or the click of a door unlocking, reinforce the physicality of the narrative space.
• Character Interactions: The diegetic sound of characters interacting with their environment, from the rustle of clothing as they move to the impact of an object they drop, enhances the realism of their presence and actions.
• Location-Specific Soundscapes: Tailoring the ambient sound to match the location, such as echoing footsteps in a hallway or the muffled sounds of conversation through walls, can significantly amplify the scene's authenticity.
• Period-Appropriate Sounds: In historical or period pieces, including diegetic sounds that are accurate to the time, like the ring of a rotary phone or the chug of a steam engine, grounds the story in its specific era.

These diegetic elements work together to pull the audience into the story's world, making the experience feel as real and immediate as possible.

Evoking Emotions with Non-Diegetic Sounds

Non-diegetic sounds wield the power to subtly or dramatically influence the viewer's emotional landscape, guiding their reactions and deepening their engagement with the narrative.

• Musical Themes: A recurring musical theme associated with a character, location, or idea can evoke specific emotions, signalling shifts in the narrative or deepening the audience's connection to the thematic elements.
• Tension Builders: Using rising musical scores or sound effects that crescendo in suspenseful moments can heighten the viewer's anticipation and anxiety.
• Emotional Punctuation: Strategic placement of music or sound effects to punctuate significant moments—such as the triumphant swell of music during a victory scene or the stark silence following a loss—can amplify the emotional impact.
• Atmospheric Music: Background music that mirrors the scene's mood, from the serene to the chaotic, shapes the viewer's emotional interpretation of the action or setting.
• Narrative Commentary: Non-diegetic sounds can also serve as a form of commentary on the action, such as ironic music that contrasts with the scene's visuals, offering a layer of meaning or critique.

By skillfully blending diegetic and non-diegetic sounds, filmmakers and video creators can craft narratives that resonate on multiple levels, engaging the audience's senses and emotions in a profoundly effective manner.

Practical Applications

Mastering the integration of diegetic and non-diegetic sounds into your video projects enhances the storytelling and elevates the overall production quality, requiring a blend of creative insight and technical prowess.

Incorporating Diegetic Sounds

Techniques for Capturing Clear Diegetic Sounds

The authenticity and impact of diegetic sounds hinge on meticulous recording techniques, ensuring they enrich the narrative without detracting from it.

• Microphone Selection and Placement: Opt for microphones tailored to your sound source. Lapel mics are ideal for individual dialogue, while shotgun mics precisely capture ambient sounds. Position mics to minimise interference and maximise sound fidelity.
• Recording Environment: Assess the acoustics of your location, aiming for environments that complement the desired sound. For indoor dialogue, rooms with minimal echo are preferable.
• Use of Booms and Windshields: Employ boom poles for directional mics to capture dialogue clearly, especially in sonically dynamic scenes. Windshields are essential for outdoor recordings to reduce wind noise.
• Layering Sounds for Depth: Record layers of diegetic sounds, from foreground dialogue to background activities, creating a rich, multidimensional soundscape.
• Synchronising Sounds with Action: Ensure sound effects accurately match the visual action, such as footsteps aligning with a character’s movement, for enhanced realism.

Editing Tips for Diegetic Sounds

Post-production offers a canvas to seamlessly refine and integrate diegetic sounds with the visual narrative.

• Balance and Mixing: Carefully adjust the audio levels to maintain dialogue clarity while allowing ambient sounds to provide context without overwhelming the scene.
• Environmental Sound Design: Strategically place ambient sounds in the mix to avoid silent voids, enriching the scene’s authenticity. Tools like EQ (equalisation) can help isolate and enhance specific sound frequencies for clarity.
• Dialogue Editing: Use compression to even out dialogue levels, ensuring consistent audibility throughout. Automated dialogue replacement (ADR) can also rectify issues with the original on-set recording.
• Foley Integration: Sometimes, recreating sounds in a studio (Foley) and adding them in post-production can achieve more realistic results than on-location recordings.

Choosing Non-Diegetic Sounds

Selecting the Right Background Music

Background music shapes a scene's emotional and atmospheric tone, requiring thoughtful selection to complement the narrative.

• Genre and Style: Align the music’s genre with the scene's setting and mood. A mismatched style can distract from the narrative flow.
• Dynamic Range and Pacing: Consider tracks with a dynamic range that matches the scene’s pacing—quieter, introspective pieces for slow moments and more intense tracks for high-stakes scenes.
• Lyrical Content: If using songs with lyrics, ensure the content supports the scene’s themes without clashing with the dialogue or action.
• Licencing and Rights: Verify the licensing of chosen tracks to avoid legal complications. Royalty-free or properly licensed music ensures your project’s integrity.

Adding Non-Diegetic Sound Effects

Non-diegetic sound effects can underscore thematic elements or highlight narrative points, but they must be used judiciously.

• Contextual Relevance: Choose effects with a narrative purpose or enhance the scene's mood without seeming out of place.
• Volume and Placement: Adjust the volume of sound effects to ensure they do not detract from the dialogue or essential diegetic sounds, using panning and spatial audio techniques for immersive placement.
• Creative Symbolism: Sound effects can symbolically represent themes or elements within the story, offering an additional layer of narrative depth without overt visual cues.
• Cohesive Soundtrack: Ensure non-diegetic sounds cohere with the overall soundtrack, avoiding jarring transitions or stylistic inconsistencies.

Effectively blending diegetic and non-diegetic sounds requires a deep understanding of their impact on the storytelling process and the technical skills to integrate them seamlessly into your projects. With practice and attention to detail, you can use these sound elements to create a more immersive, emotionally engaging video experience.
