When we think about the elements that make a film captivating, visuals often come to mind first.
However, sound plays a crucial role in creating an immersive and engaging cinematic experience.
In the realm of sound design, two terms frequently used are “diegetic” and “nondiegetic” sound.
Understanding the distinction between these two types of sound can enhance our appreciation for the artistry behind filmmaking and its impact on storytelling.
Diegetic vs. Nondiegetic Sound
Diegetic Sound: Diegetic sound refers to audio elements originating within the world of the film or video, such as characters’ dialogues, sounds made by objects in the story, or music represented as coming from instruments within the story world.
Nondiegetic Sound: Nondiegetic sound, on the other hand, includes all the audio elements that are not present within the world of the film but are added for the audience’s experience, such as background music, voiceovers, or sound effects added in post-production.
Below we look more into diegetic and nondiegetic sound, exploring their definitions, examples, and the effects they have on the audience.

What is Diegetic Sound?
Diegetic sound refers to any sound that originates from within the world of the film.
It is the audio that the characters themselves can hear, whether it be dialogue, footsteps, or environmental sounds.
Diegetic sound is an integral part of the narrative and helps to establish the film’s setting, atmosphere, and realism.
Examples of diegetic sound include:
- Conversations between characters
- Background noises like traffic, birds chirping, or rain falling
- Footsteps or other sounds made by characters as they move
- Music played by characters within the story (e.g., a character playing a guitar)
Diegetic sound can be further categorized into three subtypes:
1. Diegetic On-Screen Sound
Diegetic on-screen sound refers to sound that originates from a source visible within the frame. It is sound that both the characters and the audience can hear.
For example, if a character turns on a radio and music starts playing, the music is diegetic on-screen sound.
2. Diegetic Off-Screen Sound
Diegetic off-screen sound refers to sound that originates from a source within the world of the film but is not visible on screen.
It is sound that the characters can hear, but the audience cannot see the source. An example of diegetic off-screen sound is when a character hears a doorbell ring from another room.
3. Diegetic Internal Sound
Diegetic internal sound refers to sound that is heard subjectively by a character within the film.
It represents the character’s thoughts, memories, or subjective experiences.
For instance, if a character is recalling a conversation in their mind, the dialogue they hear is diegetic internal sound.
What is Nondiegetic Sound?
On the other hand, nondiegetic sound refers to any sound that does not originate from within the world of the film. It is sound that the characters cannot hear, but the audience can.
Nondiegetic sound is often added during post-production and serves various purposes, such as enhancing emotions, guiding the audience’s attention, or providing commentary on the narrative.
Examples of nondiegetic sound include:
- Background music or score
- Narration or voice-over
- Sound effects that are added for dramatic effect
Nondiegetic sound can be further categorized into two subtypes:
1. Nondiegetic External Sound
Nondiegetic external sound refers to sound that is added to the film from an external source.
It includes elements like background music, voice-overs, or sound effects that are not part of the film’s narrative world.
This type of sound is commonly used to create emotional impact or to guide the audience’s emotional response.
2. Nondiegetic Internal Sound
Nondiegetic internal sound refers to sound that represents a character’s thoughts or emotions but is not heard by other characters within the film.
It is often used to provide insight into a character’s mindset or to create a sense of subjectivity.
For example, if a character is feeling anxious, nondiegetic internal sound may include a pounding heartbeat or distorted sounds.
The Role and Impact of Diegetic and Nondiegetic Sound
Both diegetic and nondiegetic sound play crucial roles in shaping the audience’s perception and emotional engagement with a film.
Here are some key ways in which they impact the viewing experience:
1. Establishing Realism and Atmosphere
Diegetic sound is essential for creating a sense of realism within a film.
By incorporating sounds that characters would naturally hear, such as conversations or environmental noises, filmmakers can transport the audience into the world they have created.
Diegetic sound also helps to establish the atmosphere of a scene, whether it be a bustling city street or a serene countryside.
On the other hand, nondiegetic sound, particularly background music or score, can enhance the emotional impact of a scene and create a specific mood or atmosphere.
For example, a suspenseful scene may be accompanied by tense music, heightening the audience’s anticipation.
2. Guiding Attention and Emotions
Nondiegetic sound, especially when used strategically, can guide the audience’s attention and emotions.
By manipulating the volume, pitch, or timing of certain sounds, filmmakers can direct the viewer’s focus to specific elements on screen or evoke particular emotional responses.
For instance, a sudden loud sound effect can startle the audience, drawing their attention to a significant event or moment.
3. Conveying Information and Subtext
Diegetic sound can provide valuable information and subtext to the audience.
For example, the sound of a phone ringing may indicate an incoming call or a character’s popularity.
Similarly, the absence of sound in a scene can be just as powerful, conveying a sense of emptiness or isolation.
Nondiegetic sound, such as voice-overs or narration, can also provide additional context or insights into the narrative.
It can offer the audience a glimpse into a character’s thoughts or motivations, providing a deeper understanding of the story.
Case Studies: Effective Use of Diegetic and Nondiegetic Sound
Let’s explore some notable examples of films that effectively utilize diegetic and nondiegetic sound to enhance their storytelling:
1. “Birdman” (2014)
“Birdman,” directed by Alejandro González Iñárritu, is known for its innovative use of sound.
The film follows the story of a washed-up actor attempting to revive his career.
One of the standout features of “Birdman” is its continuous, seemingly unbroken shot, which creates a sense of immersion and intensity.
The film cleverly blends diegetic and nondiegetic sound to blur the boundaries between reality and the protagonist’s perception.
The audience hears the diegetic sounds of footsteps, conversations, and applause, which contribute to the film’s realism.
However, the film also incorporates a percussive score that represents the protagonist’s inner thoughts and emotions, creating a unique and immersive auditory experience.
2. “No Country for Old Men” (2007)
The Coen Brothers’ “No Country for Old Men” is a masterclass in the use of sound to build tension and suspense.
The film’s sparse dialogue and minimalistic approach to music allow the diegetic sounds to take center stage.
The audience becomes acutely aware of every footstep, creaking floorboard, or distant gunshot, heightening the sense of unease and impending danger.
The absence of a traditional score in “No Country for Old Men” creates a stark and unsettling atmosphere, emphasizing the raw and brutal nature of the story.
By relying on diegetic sound, the film immerses the audience in the characters’ world and amplifies the impact of each sound.
