Air Horn Frequently Asked Questions

How Do Air Horns Work?

Air horns are pneumatic devices that operate by air pressure. The device consists of a source that produces compressed air passes to a trumpet or horn through a diaphragm. Vibrations in the air stream create sound waves, which get amplified by the trumpet. 

Air horns are typically seen on large vehicles such as buses and trucks that need to alert the traffic of their impending arrival. In addition, air horns also help scare off wild animals or as warning devices in ambulances. 

Broadly, air horns are of two types.

  • Low-frequency air horn: Low-frequency air horns produce sound frequencies with a low pitch. For example, you typically see these types of air horns in cruise ships or cargo freighters. The sounds produced by them are effective and travel large distances in a small amount of time.
  • High-frequency air horn: These types of air horns produce high-pitched sounds and are great for public roads. However, most people find the sound produced by them annoying and it isn’t very effective as it cannot travel a large distance.

Are Air Horns Legal?

Yes. Firstly, Most states make it illegal to have a vehicle horn that does not have a range of at least 200 feet (60 meters). A 120dB sound level has the ability to travel up to 18 meters.

Secondly, most air horns have a sound level of 150db or less, which is ideal for roadways.

However, it is illegal to use very loud sirens unnecessarily. Overly loud horns are a nuisance for ears.  That is to say, use them to prevent accidents or to make way through traffic ( if you use them on an ambulance or a fire truck). Therefore, use your air horns cautiously. 

Should You Buy a Plastic or a Metal Air Horn?

Metal air horns are ideal if you want your horn to produce deeper sounds. However, a plastic air horn would be a better choice for mid-range tones. More importantly, whichever you choose, aim for a weather-resistant construction that will last longer.
