Bio: A common and yet simplest element of all automobiles is the horn. Although it is a basic accessory, unfortunately not much attention is paid to it. Everyone knows how to use the horn, but do we know when to use it, what tone and intensity it should have, and why did this safety element come about? These are just some of the questions you may not know the answers to about your car's horn.

The horn, also called horn, is an element that contributes to improve safety, as long as its use is correct, do you think you could change it?

The horn was born in the 19th century in response to the need to warn of the presence of motor vehicles. Before its appearance on the market, vehicles had to be preceded by a person carrying a flag or a lantern at nightfall.

The first electric car horn was introduced in 1921.

At first, various options were studied for including acoustic signals in vehicles. One of them consisted of a bell that sounded every time the wheels made a complete turn.

It would not be until April 1914 that the manually operated horn would become electronic, when Robert Bosch filed the first patent in Germany for the first electric horn for the automobile, which would not see the light of day until 1921.

Horns cannot exceed 20 db and must be regulated at a distance of 7 meters (23 feet).

Did you know that not all horns are the same?

Indeed, not all horns have the same sound, as they must be adapted in intensity to the size and power of the vehicle. This means that a train or truck horn cannot be installed in a car and vice versa. In addition, horns can reach intensities of 120 db, although they must be regulated to 105 db at a distance of 7 meters.
