What are three purposes of sound effects?

The chosen answer outlines three essential purposes of sound effects in film and video production. Sound effects are critical in enhancing the overall experience of the audience by fulfilling various roles:

1. Set the mood: Sound effects can deeply influence the emotional atmosphere of a scene. For example, the presence of thunder or howling winds may create a sense of tension or foreboding, while cheerful birds chirping might evoke a joyful or peaceful feeling. This atmospheric influence helps to immerse viewers in the story.

2. Simulate reality: Sound effects are vital in creating a believable world in audiovisual media. Realistic sound effects, such as footsteps on gravel or distant city noises, help ground the visuals in a more tangible reality. This simulation of real-life sounds aids the audience in relating to the content more effectively.

3. Create an illusion: In storytelling, sound effects can be used creatively to produce an illusion that enhances the narrative. For instance, fantastical sounds may indicate magic or supernatural elements, while exaggerated sounds can heighten the impact of actions (like the dramatic crunch when a character steps on something). These illusions engage the audience's imagination and can amplify key moments in storytelling.

Understanding these functions helps filmmakers and editors make informed choices about sound design, thereby
