air horn
Compressed gas alarm
An air horn is a loud signaling device that produces sound by forcing compressed air through a horn.
The portable canister type, common at sporting events and on boats, emits a harsh blast: Fans blasted air horns after the winning goal.
Larger air horns on trucks and trains serve as warning signals.
