The sound design creates a vertical landscape. As Tess moves deeper, the audio mix places the audience underground. The reverb on her breathing and footsteps grows longer, signaling a vast, empty space. Crucially, the audio track introduces the "Mother" character not through visuals, but through sound. The creature’s vocalizations—a terrifying blend of human-like wailing and animalistic grunting—are mixed to feel uncomfortably close, often panning from behind the viewer to the front speakers, simulating the sensation of being hunted in the dark.
