Non-Diegetic Sound – Definition & Detailed Explanation – Sound Design Glossary Terms

I. What is Non-Diegetic Sound?

Non-diegetic sound refers to any sound that is not part of the narrative world of a film or television show. This type of sound is typically added during the post-production process and is used to enhance the viewer’s experience by creating mood, atmosphere, or emotional impact. Non-diegetic sound can include music, sound effects, and voiceovers that are not coming from within the scene itself.

II. How is Non-Diegetic Sound Used in Film?

Non-diegetic sound is used in film to convey information, create tension, set the mood, or evoke emotions in the audience. For example, a suspenseful scene may be accompanied by eerie music to heighten the tension, while a romantic scene may be enhanced by a soft, melodic soundtrack. Non-diegetic sound can also be used to transition between scenes, indicate a change in time or location, or emphasize a character’s thoughts or feelings.

III. What is the Purpose of Non-Diegetic Sound?

The purpose of non-diegetic sound is to enhance the overall viewing experience and immerse the audience in the story being told. By adding music, sound effects, or voiceovers that are not part of the on-screen action, filmmakers can create a more dynamic and engaging narrative that resonates with viewers on an emotional level. Non-diegetic sound can also help to establish the tone and atmosphere of a film, guide the audience’s emotions, and provide important context or information.

IV. How is Non-Diegetic Sound Different from Diegetic Sound?

Non-diegetic sound differs from diegetic sound in that diegetic sound is any sound that originates from within the world of the film or television show. This can include dialogue between characters, sounds made by objects or characters in the scene, or ambient noise that is part of the setting. Non-diegetic sound, on the other hand, is added in post-production and exists outside of the narrative world of the film. It is not heard by the characters on screen and is used to enhance the storytelling experience for the audience.

V. What Techniques are Used to Create Non-Diegetic Sound?

There are several techniques used to create non-diegetic sound in film and television. One common technique is the use of a film score, which is composed specifically for the movie and is used to underscore key moments, create tension, or evoke certain emotions. Sound effects are another important tool in creating non-diegetic sound, as they can add depth and realism to a scene or enhance the overall atmosphere. Voiceovers are also commonly used to provide narration, inner thoughts of characters, or additional context to the story.

VI. How Does Non-Diegetic Sound Enhance the Viewer’s Experience?

Non-diegetic sound plays a crucial role in enhancing the viewer’s experience by adding depth, emotion, and atmosphere to a film or television show. By using music, sound effects, and voiceovers that are not part of the on-screen action, filmmakers can create a more immersive and engaging narrative that resonates with audiences on a visceral level. Non-diegetic sound can help to establish the tone and mood of a scene, guide the audience’s emotions, and provide important context or information that enhances the overall storytelling experience. Ultimately, non-diegetic sound is a powerful tool that filmmakers use to create a more dynamic and compelling viewing experience for audiences.
