Why do we use the word sirens for an emergency alarm?

The term "siren" for emergency alarms is derived from the mythical creatures in Greek mythology that lured sailors to danger with their enchanting songs. In modern usage, sirens emit loud, piercing sounds designed to alert the public to imminent danger or emergencies, much like the sirens of mythology signaled peril. The name reflects the idea of drawing attention quickly and effectively to situations that require immediate action.
