The Evolution Of The Car Horn

Car horns are unique because they are the background soundtrack for many cities around the world. There are many interesting aspects of vehicles for a car enthusiast; it makes it easy to take the car horn for granted. Below is a glimpse of the history of the car horn and its modernization over the years.

Before there were interstates, in a period of horseless carriages – drivers used bells, whistles, and even hand-squeezed horns to notify pedestrians and other drivers of their presence. It wasn’t until 1908 that young inventor Miller Reese Hutchison patented the Klaxon Horn. Hutchinson, who also worked alongside Thomas Edison, created two versions of his Klaxon Horn. According to MoparMagazine, one version of the horn was motor-powered with batteries, and the other was manual with a small hand crank. Both versions of the Klaxon Horn gave a distinctive “aoogha” to announce each vehicle’s presence. Today if you honk at a pedestrian, you may startle them or be met with hostility. In the early 1900s, honking to notify pedestrians of your vehicle was considered polite.

By the 1930’s the Klaxon Horn began to lose its popularity to the electric horn. While the Klaxon Horn’s “aoogha” is still infamous to this day, the tone of car horns has evolved over the years. According to Car and Driver, Bosch is still the leading supplier of car horns for major vehicle manufacturers. Bosch created modern car horns in three different categories: the disc horn, compressor trumpets, and the fanfare horn. Commercial vehicles typically use the compressor trumpets. In contrast, the disc horn and fanfare horn are meant for personal vehicles. Disc horns are described to have a metallic sound while fanfare horns sound fuller and more harmonic.

Today car horns are mandatory on all vehicles, and depending on which state you’re located in, their usage may have special regulations. Many state regulations are based on how audible a car horn is or how loud it is. For example, in a state like New York with many large cities, car horns hold vague restrictions such as not being ‘unnecessarily loud or too harsh’. While a car horn may be a nuisance today, they do a great job of notifying others and keeping each other safe.
