How Loud Are Semi Truck Horns?

Semi truck horns are one of the loudest sounds on the road. They have to be able to be heard over the roar of engines, brakes, and tires.

Semi truck horns are usually mounted on the cab of the truck, with some located on the front bumper or grille. The horns are usually made out of metal or plastic and can range in size from small to large. Most semi truck horns have a volume range of 85-115 decibels (dB), which is equivalent to a jet taking off at 25 feet away.

For comparison, most car horns average around 110 dB, while a rock concert can reach up to 120 dB. The reason semi truck horns are so much louder is because they need to be heard from further away than car horns. Semi trucks typically travel at higher speeds than cars and need to alert other vehicles quickly when they are about to pass.

Different Types Of Semi Truck Horns

Semi truck horns come in a variety of sizes and styles. Some common types include:

  • Air Horns: These are some of the loudest and most popular semi truck horns available. Air horns use compressed air to create their sound and can produce volumes up to 150 dB.
  • Electric Horns: Electric horns use electric current to create their sound, and they can be mounted on both sides of the cab for dual sound output.
  • Bullhorns: These horns feature two tubes that project sound forward in a cone-like shape for maximum distance.

It is important for them to be able to alert nearby vehicles when they need room for passing or when they need other drivers’ attention in order to avoid potential accidents. The loudness of the horn also serves as an extra deterrent against reckless drivers who may not pay attention otherwise.
