How Air Horns Work

Air Horn Diagram

Pressurised air is forced through a compression chamber which then vibrates a diaphragm the compression chamber is remains pressurised to allow the horn to sound instantly when the horn switch is pressed, when the horn switch is pressed a valve will open and allow the air to be released from the chamber into the horns throat, when the air exits the chamber the diaphragm starts to vibrate and a sound is produced.

The length of the horn and the horn mouth determine the tone and volume that will be created.

Achievable Sound levels

  • 100-120db
  • 120 – 140db
  • 140 – 160db

Voltages

  • 12 volts
  • 24 volts
  • 12/24 volts

Air horns can be used on various types of vehicles such as trucks, trains, or even in a work environment as a warning sound, such as oil rigs, large factories or stadiums.

Horns can be mounted to a vehicles roof, or within the engine bay with easy to attach fixing brackets.

Wiring Air Horns on a Truck

The air horns on a truck can be wired to sound with the trucks regular horn or can be wired to a seperate switch or button.

Wiring air horns separately can be advantageous because air horns may not be legal in certain areas because of the amount of decibels they produce.

Most truck drivers will fit the trumpet part of the air horns to the roof of the truck cab or onto a roof bar, an air tube will need to be fed to the compressor that provides the air to the horn, it is best practice to locate the compressor as close to the trumpet as possible, some modern truck air horns have the compressor built in to the trumpet section of the horn.

The compressor will be powered electrically by the trucks electrics, this will require wiring it into the horn circuit or wiring it separately to a switch, always read the installation guide that comes with your air horns as installation may vary with different makes of air horns.
