What sounds do humans use to warn of danger?

Humans use a variety of sounds to warn of danger, including loud vocalizations like shouting or screaming, which can signal immediate threats. Sirens and alarms are commonly employed in public settings to alert people to emergencies, such as fires or severe weather. Additionally, the use of horns or whistles can communicate danger in specific contexts, such as on roads or in sports. These sounds aim to capture attention quickly and prompt a swift response to potential hazards.
