Air Horns – How They Work, And How To Install Your Own
How Air Horns Work
Air horns work by using pressurized air to vibrate a diaphragm located within a compression chamber. This chamber is kept pressurized to ensure the horn sounds instantly. When activated by a switch or button, a valve opens allowing air to escape out of the compression chamber and into the base of the horn (known as the “throat”).
On each of our product pages, you’ll also see a decibel (dB) rating for how loud a particular horn is. Typically, train and truck horns range from 110 to over 150 decibels (db). For perspective, the quietest sounds a human ear can detect are 10 dB. Conversely, sound begins to become painful in close proximity around 130 dB.
Installing an air horn is simple. Detailed instructions from the manufacturer will guide you through each step, from mounting to wiring and these are included with our kits.
Suitable for auto car, trucks and other DC 12V vehicles.
