(A long, low, resonant tone begins, building slowly in intensity. It's punctuated by short, sharp bursts of static, like a radio signal struggling to maintain clarity. The tone deepens, becoming almost subsonic, creating a feeling of unease and impending dread. A high-pitched, wavering whine then cuts through the low tone, mimicking the sound of a police scanner struggling to pick up a frantic transmission. This whine increases in frequency and intensity, becoming almost a shriek before abruptly cutting out. The low resonant tone continues, but now with a more erratic, pulsating rhythm, suggesting a chaotic and unpredictable event. After a few seconds of this pulsating tone, a series of rapid, staccato bursts of sound – like distant sirens or explosions – are layered over it, adding a sense of urgency and chaos. The overall effect is a gradual crescendo, building from a low, ominous hum to a cacophony of unsettling sounds, before abruptly cutting off, leaving a lingering sense of unease and anticipation.)
