Why Do We Need Car Horns?

Thanks to the signals and automobile horns, road safety is being increased and, in turn, the number of accidents is minimized. We cannot skip the fact that the majority of accidents could be prevented by giving a warning signal in time. In addition to the safety function, the best car horns enhance a car’s exterior design.

Thanks to this simple device, you can hear the “voice” of a car, with the help of which the car will report its presence to people and other drivers around. Hence, the presence of this tool, which emits a special sound, will allow you to avoid many emergencies and provide the possibility of communication between drivers by using signaling.

It is a very important and necessary part that must be in every vehicle. And if it fails or performs its functions inappropriately, then a driver starts to think about purchasing a new device. And then a new problem arises and the question which one to choose and what should I consider when choosing a car horn?

Things to Watch Out

During its performance, a regular car horn may become unusable or the auto owner will want to replace it because of a desire to hear a different horn sound. To carry out the tuning of the sound system of your vehicle, you can choose different versions of car horns, which can also provide the auto with a certain personality, thanks to which it will be possible to stand out in the stream of cars.

First of all, when choosing a sound signal, you need to consider the size of the horn and the mounting option. You must be sure that the installation will be quick and easy. This will help you to avoid additional manipulations and expenses for hardware specialists. In the end, if the car horn does not fit you in size, you will have to spend your time on returning or exchanging the product. Also, pay attention to the appearance of the signal. A car horn should fit the appearance of your auto. Moreover, it shouldn’t look like an extraneous element on the body.

Another thing that you should pay attention to when choosing a horn is the voltage. Car horns for vehicles use a voltage of 12 volts. However, the best and the most powerful for trucks use 24 volts.

Technical Terms

The sound level is the air pressure level, and the measuring unit is decibel. All the sounds we hear are just changes in air pressure that reach our eardrum. Only when they are transmitted to our brain do they turn into information there. Depending on the energy at which changes in air pressure or sounds reach the eardrum, the sounds can be either quiet or loud. Consequently, the more energy a sound has, the louder it seems to us. 

To measure the intensity of sound, we use a unit of measurement called decibels “dB”. The lowest level of audible sound, that is, the quietest sound that a person can hear is 0 decibels. A sound level of 50 dB is pleasant to us, a level of 100 dB is considered the threshold of pleasure, and at the level of 120 dB is the limit of pain.

The voltage is compared with the energy potential of the fluid source. For example, an increase in hydraulic pressure by a pump in a pipe will create a greater rate of fluid movement, and an increase in voltage. By default, cars use 12 V, and trucks use 24 V. For instance, the electric power in an average home is 110 V. 

Types of Car Horns

Pneumatic car horns

The sound signal in such a device is generated by the ingress of air from the compressor into the horn tube, in which a sound signal is generated due to air vibration. Such car horns are different in the number and shape of the pipes used, as well as the power of the sound system. Their total power can reach 120 dB, and the frequency range of the device can cover several sound zones.

Electromagnetic car horns

This type of car horns is based on the principle of operation of an electromagnet, which is its primary element. The electromagnet is connected to the membrane, and the core winding is connected through a chopper to the battery. The signal button located on the steering wheel is connected to the mass of the vehicle. Thus, when it is pressed, the core rod oscillates by moving the horn membranes. As a result, there is a very loud sound.

Electronic car horns

Well, the main component is the chip that generates the sound of the required frequency, after which it transfers it to the loudspeaker. The sound reproduction power can reach up to 110dB, in frequency, then it can be very different in various models. These devices are versatile and easy to operate. They can operate on 12 or 24V. Also, various models reproduce a variety of sounds from ordinary monophonic signals to whole melodies.
