A piercing electric school siren wails in a steady urgent tone for about eight seconds, the kind used as a class bell signal. It feels harsh, stressful and funny at once because listeners instantly hear it as an order to move or sit down. It comes from the familiar sirens used in Brazilian schools to mark lessons, breaks and dismissal.
