Naval klaxon alarms have been used on military ships and submarines for decades to signal general quarters and emergencies, with a distinctive repeating tone that carries across noisy decks. That recognisable pattern moved into films, television and cartoons, where it became shorthand for a ship in trouble or a crew rushing to stations. Online, creators reuse the same sound for comedy and tension, pairing the serious military warning with everyday mishaps, gaming defeats and animated panic for contrast.
