siren (Alarm)
A siren is a loud noise-making device used to alert people to emergencies or dangers. It produces a high-pitched sound that can be heard over long distances, making it effective for warning communities about events like fires, severe weather, or other threats. Sirens are commonly found on emergency vehicles, such as ambulances, fire trucks, and police cars, as well as in fixed locations like fire stations and emergency alert systems.
Siren sounds can vary in tone and pattern, often designed to grab attention quickly. They are an essential part of public safety systems, helping to ensure that people are informed and can take appropriate action during critical situations. The use of sirens is regulated in many areas to prevent misuse and maintain their effectiveness in emergencies.
