air raid sirens
Bombing alert signals
Air raid sirens are loud warning devices designed to alert civilians of incoming aerial attacks or other emergencies.
The distinctive wailing sound—rising and falling in pitch—became iconic during World War II and the Cold War.
Today they're used more broadly for tornado warnings, tsunami alerts, and other civil defense purposes: The air raid sirens sent everyone scrambling for the basement.
