Etymology: Airhorn is a compound of "air" and "horn," and the "horn" half is the older and more interesting part. Horns were among the earliest sound-making tools: animal horns, shells and carved wooden or metal trumpets were used for signalling across fields and battlefields long before anything was powered by gas. The English "horn" comes from Old English "horn," tracing back to a common Germanic root, and it originally meant the hard projection on an animal's head. The modern airhorn belongs to a much later era. Compressed-gas horns of this kind developed in the twentieth century, using a pressurised canister and a diaphragm or reed to produce a loud blast, and they were adopted first for ships and vehicles before spreading to stadiums and celebrations. The name simply describes the mechanism: air, forced through a horn-shaped tube. Its history is a plain one, so the term is best understood as a technical compound rather than a word with a dramatic backstory.

Synonyms: air horns, vehicle horns, truck horns, train horns
