This is a short, loud air raid siren that wails for about two and a half seconds, with no voice or music in it. It feels tense and alarming at once, turning a quiet scene into an emergency in a single blast. It draws on the civil-defense siren used to warn of wartime aerial attacks, which is why listeners recognise the danger instantly.
