How to Clean an Electric Valve for Air Horns
The pressure needed for the horns
An air horn is a pneumatic device designed to create an extremely loud noise for signalling purposes. It usually consists of a source which produces compressed air, which passes into a horn through a reed or diaphragm. The stream of air causes the reed or diaphragm to vibrate, creating sound waves, and the horn amplifies the sound so it is louder.
