A warning siren is a loud, attention-grabbing device used to alert people about emergencies or dangerous situations. These sirens can signal various events, such as severe weather, natural disasters, or public safety threats. They are often installed in communities to ensure that residents are informed quickly and can take appropriate action. Warning sirens typically produce a distinct sound, such as a wailing or steady tone, making them easily recognizable. They are commonly associated with emergency services, such as police and fire departments, and are part of a broader emergency alert system designed to keep the public safe during critical situations.
