Morphology
The meaning is directly compositional: a 'horn' (a loud signaling device) that uses 'air', so a learner who knows both words can infer a horn powered by compressed air. This noun‑noun compound follows a common, cross‑linguistic pattern and is therefore immediately understandable to a B1 learner.
Etymology
Air horn for engines gets its name from a horn-like tube that helps guide air into the carburetor. Because it looks and works like a horn that directs the flow, the word came to mean 'the opening where air enters'.
