Reasons for Getting a Quality Air Horn for Your Truck

It will come in handy, especially when you are traveling at high speed or stuck in traffic. Make your horns to be loud and meaningful by going for the best. There are various air horns that you can buy for your truck and which will be able to serve you well.
There are various factors you need to consider before you purchase one and that is how this buying guide is going to help you in narrowing down what you think is best for you. All you need to do is to get the best that will work for your own truck.

Things to Consider When Purchasing Truck Air Horns

Truck air horns are an essential accessory for your truck, which has gained a lot of popularity over the years. You can purchase some of the best online or in the market near you. You will have to pick the best amongst the many different options in the market. You will need to consider the following before going out to purchase one for your truck.

1. Sound

The sound is the most important factor that you need to consider when buying an air horn for your truck. Take into consideration the sound the horn will produce and the kind of sound you want it to produce. You will get two varieties easy to get in the market or online; the one that uses tanks and air compressors and another one that uses a direct drive system.

If you decide to go for the direct system, it includes an air pump that is small in size, that ensures that air is pumped into a small set of horns directly. The air compressor one builds pressure in the tank up to 200 PSI.

The pressure is held in the tank until the horn triggers it which an electronic solenoid triggers, and which is is found in the horn during installation. It is very loud as compared to the direct system and its blast is 148 to 153 dB. There are some systems which can go up to 157dB and this will depend on the size of the valve and type of horn.

The sound created depends on the number and size of the trumpets that are in your sets. Trumpets, which are thinner and shorter tend to produce a higher pitched sound while those which are wider and longer produce a tone that is deeper.

When you purchase the horns, they will come with a set of 2 to 4 trumpets that are designed to blend quality and sound of the horns. The air horns which you will find in the market have 3 to 4 trumpets which make a better sound that is louder than traditional train horns. When buying horns for your truck, the sound is the most important thing to consider.

2. Air Requirements

The air system of a truck air horn has three features that are important and which you need to pay close attention to; work pressure, tank capacity, and the compressor duty cycle. The working pressure in the air system has to comply with a general rule which says; the higher the pressure, the higher and louder the sound that will be produced by the horn.

The tank capacity refers to the amount of air which can be stored in the tank which will determine how long the horn can hold before the air is refilled in the tank. The duty cycle in the compressor rating is calculated by the complete off and on cycles maximum running time in the form of a percentage.

You need to consider the tank size in order to ensure the proper duty cycle is achieved, expected frequency of use and the multipurpose air is also very important. When it comes to air horns, you need to keep in mind all these features before you decide on which air horn is best for you. Even though the details might seem tiny, they have a strong impact on the length, sound, and quality of the air horn.

3. Sealed And Non-sealed Air Systems

If you install an air horn and it fails to work, it might be that you have installed the compressor in the wrong location. The tank system and the compressor must be installed in a dry and clean area.

If you happen to mount them in an area that is exposed, it might allow water and dirt to attack and get them into the chamber, resulting in the compressor being damaged. Such damages are not covered by the manufacturer in the warrant and thus, you need to always remember this.

And to avoid such from happening, you will need to consider purchasing an air system that is sealed, which has a compressor sealed with a gasket that allows you to mount the air horn on the external of the chassis of the truck. Although it is initially expensive, in the long run, you will give your air horn reliability and extended life.

4. Installation

You need to consider how the air horn is going to be installed on your truck when you are purchasing it. You need to know where you will mount it and on which component. I have installed mine in the engine compartment below the vehicle on the frame rails.

There are different sizes of air horns easy to get in the market or online and thus, you will need to look for the dimensions of the one you are choosing and then choose wisely. Once you have bought it, you will need to know how to install it or take it to a professional to do it for you.

If you are planning to do it yourself, you can watch online videos or go through the manual of your air horn.


1. How Do Truck Air Horns work?

There is a source in the truck air horns which produces compressed air. When this compressed air passes inside the diaphragm of the horn, it makes it vibrate, creating sound waves which are followed by the horn amplifying the sound to make it even louder.

2. Can Your Ears Be Damaged by Air Horns?

It is important to note that, hearing can vanish by being in a place where there is a lot of noise. And when they stop hearing, there is nothing you can do to restore it again. You will need to ensure that your air horn emits a maximum of 129 decibels and nothing more than that. You should also note that a sound more than 85 decibels are likely going to cause hearing loss. This means that it is likely that, your ears can be damaged by air horns.

3. How To Make Air Horns Louder

The air horn is already louder and there is no need to modify it to make it louder than it is. The best you can do is to ensure that you buy the one that has the sound that you feel is comfortable for you and which is the loudest. But you should ensure that it is not more than 129 decibels for the love of your ears. Different air horns have different decibels and thus, choose the best for yourself.

4. Do Truck Must Have Air Horns?

It is necessary, but not a must. If you are comfortable with the regular horns on your truck, then no need. But because the trucks make a lot of other noises, it is necessary for you to adjust the sound of the horns by installing the air horns to help you in signaling while moving in traffic or at high speed.

5. Are Truck Air Horns Legal?

Every country has its own set rules and regulations set by the vehicles and transport licensing board. You will need to look out for the set limitations in the area you reside to know if having air horns is legal or not. In most cases, there is a common line that states that the horn needs not to be blown out unnecessarily, loud and harshly. This means that you cannot install a horn on your truck, which is harsh and loud.


Air horns for the truck are available in various sizes and different features. This is what makes the market of truck horns to be full of different options and wide. There are various manufacturers who are competing with each other to make it to the top. You will need to be keen so that, you get the best out of the many that are being advertised. Get the best out of the 10 I have tried to review in this article, but if you don’t get your best choice, you can check on Amazon for other options.
