This is a short police siren effect lasting just under four seconds, built from a loud rising and falling wail like a patrol car passing close by. It feels urgent and tense, instantly putting listeners on alert, which is why the same wail can feel serious in one moment and playfully dramatic when it interrupts something ordinary.
