The air horn is a pneumatic device designed to create an extremely loud noise for signaling purposes. Here at Outdoor shopping we offer the best portable loud air horns on the market. An air horn is 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. Air horns are widely employed as vehicle horns, installed on large semi-trailer trucks, fire trucks, trains, and some ambulances as a warning device, and on ships as a signaling device.Portable air horns are also readily available packaged with a can of compressed air as the air source. These are often sounded by fans at sporting events such as American football, basketball, hockey and association football, and at other outdoor events. Small versions are sometimes used as bicycle horns or non-lethal weapons for self-defense, mainly as an auditory distraction to get away from an attacker.
