Buyers Guide

This great accessory for your truck has gained a lot of popularity over the years. There is a huge variety of the loudest and train air horns for trucks available for purchase in the market and online.

The main purpose of this buyer’s guide is to share some of the information that we have gathered from communicating and interacting with different customers over time in order to help you people pick the best air horn for your truck amongst the many different options available.

So we have listed below the elements of consideration you must know before buying the air horn for your truck.


The sound of the air horn is the most important factor to be considered when buying an air horn system for your vehicle. You will want to consider how loud the horn must be and what type of sound should it create.

There are two types of air horn systems available in the market, the direct drive system and the other one that uses an air compressor and tank.

The direct drive system includes a small air pump that pumps air directly into a small set of horns.

These may be perfect for motorcycles or standard cars but not good for extremely loud sound which we want. So we just skip this one.

The second type of air system as a compressor that builds pressure in the tank up to 200 PSI. The tank holds up the pressure till we trigger the horn.

The horn is triggered by an electronic solenoid installed in the horn. This system is much louder and the blasts from these types of horns are of 148 to 153 dB.

Some systems may reach up to 157 dB depending on the type of horn and size of the valve.

You may see many advertisements that say 170 or 180 dB, ignore them because that is not possible for air horn systems.

The type of sound created by a set of horns is dependant on the size and number of the trumpets in the set.

Trumpets that are shorter and thinner produce a higher pitched sound and the longer and wider ones will produce a deeper tone.

Mostly the horns come with a set of 2 to 4 trumpets which are designed to blend the sound and quality of sound.

The train horn sound is made with 3 large trumpets that have 6” wide bells. Train horn kits sound really nice but are very loud.

The air horns available on the market have 3 to 4 trumpets that will make better sound and louder than any traditional train horn.

The sound is definitely the most important thing to be considered when buying the air horn for trucks.

Air Requirements

The air system has three important features that need your attention. Tank capacity, work pressure, and the compressor duty cycle.

The Tank capacity is the amount of air that can be stored in the tank which will determine the how long can you hold the horn till the air has to be refilled in the tank.

The working pressure in the air system has a general rule that says that higher pressure will result in a louder sound of the horn.

The compressors have a duty cycle rating that can be calculated by the complete on/off cycle’s maximum running time as a percentage.

For example, a 25% duty cycle compressor can run straight up to 15minutes but must cool for 45 minutes.

To ensure proper duty cycle you must consider the tank size, multi-purpose air and expected the frequency of use.

For the air horns, you need to keep in mind all these features before making your final decision. Your choice must reflect your knowledge and requirements.

These tiny details have a great impact on the sound, length, and quality of the air horn.

Sealed and Non-Sealed Air Systems

Installing the compressor in an inappropriate location is the most common reason for an air horn system failure. The compressor and tank system must be installed in a clean and dry area.

Mounting them in an exposed area may allow dirt and water to attack and make way into the chamber resulting in damage to the compressor.

The manufacturer will not cover this in the warranties so you must keep this in mind as well. To help prevent this, consider buying a sealed air system.

The sealed air systems have compressors sealed with gaskets that allow you to mount the air horn externally on the chassis of the heavy vehicle.

This might be an expensive option but will give your air horn an extended life and reliability.


The last and essential point to consider when buying the loudest air horn for your truck in the installation.

You must know where you will be mounting the components. We usually install this in the engine compartment below the vehicle on the frame rails.

The air horns come in a variety of sizes so you must look for the dimensions and choose wisely.

Once you are done with buying it, you must know how to install it or you can go to any workshop that will do it for you.

But if you are planning to do it yourself, there are many videos and guides on the internet that will help you at this stage as well.

Frequently Asked Questions

1. How do air horns work?

Air horns consist of a source that produces compressed air. This compressed air passes goes inside the horn through a diaphragm.

This way the air stream makes the diaphragm vibrate, creating waves of sound which is followed by the horn amplifying the sound to make it even more louder.

2. Is it legal to have an air horn on your truck?

Every country or state has its own rules and regulations. The transport and vehicle laws set limitations on different aspects of this area.

The one thing common in these laws is a line that states that a horn must not be blown out loud, unnecessarily and harshly. So you cannot have an air horn with an extremely loud and harsh sound.

3. Can air horns damage hearing?

You need to know that being around too much loud noise can cause your hearing to vanish.

And once your ears stop hearing, they won’t be hearing anything again. 129 decibels is the average noise an air horn emits.

On the other hand, any sound above 85 decibels can make you lose your hearing. So this proves that air horns can damage hearing.

4. How loud are air horns?

As told earlier, an air horn emits 129 decibels of noise. As compared to a cowbell that produces 110-decibel noise, an air horn has a much louder sound.

Different air horns have different decibel levels. So choose wisely.

5. How many decibels can kill?

An air horn won’t kill you but it can take away your hearing ability or get your hearing aid.

150 decibels are enough to burst your eardrums which is quite painful. 185 to 200 decibels can kill a person.

So don’t worry, an air horn will not kill you with 129 decibels of noise emission.

6. How many decibels is a semi-truck horn?

An extensive business truck can create air horn decibel dimensions of around 150 decibels. For examination, a power yard trimmer produces 100 decibels of sound.

Regularly, vehicle air horns don’t achieve higher than this decibel level.

7. Why are air horns so loud?

The wave of air makes the reed or stomach vibrate, making sound waves, at that point the horn enhances the sound making it more intense.

These are commonly used in large-semi vehicles like trucks, ambulance, and fire trucks.
