Surround Sound

Definition

Surround sound is an audio system designed to create an immersive listening experience by utilizing multiple audio channels and speakers positioned around the listener. This setup enhances the perception of sound directionality and depth, making it feel like the sound is coming from various points around the listener, rather than just from a single source. It's particularly important in immersive environments where creating a realistic auditory experience enhances the overall impact of the set design and contributes to storytelling.
