This five-second clip is a police siren wailing in a rising and falling two-tone pattern, the kind heard from an emergency vehicle passing on a street. It feels urgent and alert, with a tense edge that makes a scene feel like trouble is arriving fast. The sound cuts through background noise and instantly signals authority, pursuit and a sudden need to pay attention.
