audible alarm
Loud alert signal
An audible alarm is a warning signal you can hear—a siren, buzzer, beep, or bell designed to alert people to danger or demand attention.
Fire alarms, car alarms, and security systems all produce audible alarms.
The term distinguishes sound-based alerts from visual ones like flashing lights: The system triggers both an audible alarm and a strobe light.
