Has your car horn seen better days or have you grown tired of the same old sound it makes? Then it's time to shop around for a new car horn. Bear in mind that a horn is required in every vehicle so that drivers will have a way to alert other motorists and pedestrians. Although automotive horns come in many different tones, shapes, and sizes, the sound they give off should be your main consideration when purchasing a new one. Here are the types of horns available in the market these days, as well as the pros and cons of every type to help you get the horn that's right for your vehicle and for your needs:
Powered by electricity coming from the vehicle's battery, electric horns produce either a low- or high-pitched sound. They can be mounted to the roof, looking like loud speakers. These horns are usually used by police cars in catching the attention of a driver. These are great if you want to customize the sound given off by your horn. If you want a louder horn, however, this type isn't for you. Its loudness is the same as that of your stock horn; it just produces different tones.
These horns make a loud noise that can reach up to 135dB compared to the 115dB stock standard. Decibels may vary per air horn. Though this type is often used in large vehicles, fire trucks, and ambulances, anyone who wants a louder horn can get this for his car.
Considered automotive accessories, musical horns replace the standard "beep" sound produced by your stock horn with music or customized sound. But before you consider getting one, check first if it's legal in your state. If it is, find out the maximum decibel level allowed.
To amplify sound, electromagnetic horns use a flexible metal diaphragm, an electromagnetic coil, a switch, and a housing. When you honk, an electrical current will run through the coil, making the diaphragm move back and forth, which then causes the air to go through the acoustical housing and produce a loud sound. Unlike other types of horn, these use more electrical power to make a sound that usually exceeds 90 decibels.
These horns were used in earlier models of automobiles. They feature a squeezable bulb that gives off sound via a metal reed. Today, this type of horn is mostly of ornamental value because it can't produce a noise that's as loud as what modern car horns emit.
