Introduction
A horn is mostly a device that produces sound and is usually mounted for vehicles like trains, cars, buses and so on. Car horns are electric most of the time and are drive by a circular steel diaphragm that is flat and has an electromagnet that is pulling it in one direct and another spring that is pulling it in another direction. The latter is most of the time attached to a contact or contact points as it will repeatedly interrupt the supply of electricity to the magnet which in return will cause the diaphragm to spring back the other way and thus completing the circuit again. This arrangement will make sure the circuit is opened and closed about a hundred time per second and will thus create a loud noise which can then be amplified by a horn to create the “honk” sound everyone is familiar with. Electric horns usually uses about 5 to 6 amperes of electricity and produce a sound level of approximately 107-109, however some can even go beyond that around the 140-160dB. The horns can be used one at a time but most of the time, they are also set up in pairs so as to produce 2 notes at a consistent interval. Called frequency pairs, the latter are designed on the 500 Hz and even 405 Hz to 420 Hz.
Nowadays, cars and motorcycles use smaller and cheaper alternatives which retains the name “horn’ but abandons the actual horn ducting and focuses onto larger diaphragms to reach the desired sound level.

PIAA is one of the newer emerging air horn manufacturer. And being new, they sure are innovative and know their stuff. Let’s see the pros and cons of this air horn.
Pros and Cons
First of all it is super light and extremely easy to install with two wires. In addition to that they resist the weather well especially rain and in some cases even floods, as long as you make sure to wash them to get the mud out. The sound is rather loud too if you are a fan of loud horns and make sure not to have your ear next to it when it honks.
The only con we could find is that you can accidentally loosen the nut when fitting it which may change the original sound output of the horn completely.
