Description
A traditional style automobile horn includes an expansion chamber cast into its body, once spiral shaped, to better match the acoustical impedance of the diaphragm with open air, and thus more effectively transfer the sound energy. Sound levels of typical car horns are approximately 107–109 decibels, and they typically draw 5–6 amperes of current. As vehicle electrics improved during the 20 th century and vehicle numbers increased on roads globally, the car horn needed to be even more effective to cope with the demands of the modern motorist. The answer was the ‘vibrating diaphragm electric car horn’, which was in development as early as the 1930s. Despite what you might think, these were intended to produce a more socially-acceptable noise, compared to the rubber-bulb and klaxon variants. The Lovell-McConnell Manufacturing Company of Newark, New Jersey bought the rights to the device and it became standard equipment on General Motors cars. [8] Franklyn Hallett Lovell Jr., the founder, coined the name klaxon from the Ancient Greek verb klazō, "I shriek". [9]
Most modern streetcars, trams and trolley cars including low-floor vehicles around the world also employ horns or whistles as a secondary auditory warning signal in addition to the gong/bell which either use the sound of air horns or electric automobile car horns. The English company Klaxon Signals Ltd. has been based in Oldham, England for the last 80 years, [ when?] with premises also in Birmingham. The French Klaxon company was acquired by the Italian Fiamm Group in the 1990s. In 2005 Klaxon Signals sold the rights for the hooter or klaxon range to Moflash Signalling Ltd., based in the original Klaxon Factory in Birmingham, England. [ citation needed] For serious volume from your horn, you need to add air. A compressor and an array of four horns like this one will give you train-like levels of noise. We wouldn't use full pressure, because you might blast everyone else off of the road, but it's there when you need it. If you want to ensure you're noticed when engaging your car's horn, this is the kit for you.Portable air horns driven by canned compressed air are also used, as well as for officiating sports events and recreational activities.
Most cars, motorcycles, and motor scooters have for some time used a cheaper and smaller alternative design, which, despite retaining the name "horn," abandons the actual horn ducting and instead relies on a larger flat diaphragm to reach the required sound level. Sound levels of such horns are approximately 109–112 decibels, and they typically draw 2.5–5 amperes of current. Again, these horns can be either single, or arranged in pairs; typical frequencies for a pair are 420–440Hz and 340–370Hz (approximately G ♯ 4–A 4 and F 4–F ♯ 4) for this design. In countries applying the Vienna Convention on Road Traffic, usage of audible warnings is limited, and allowed only in two cases: [10] Ships signal to each other and to the shore with air horns, sometimes called whistles, that are driven with compressed air or from steam tapped from the power plant. Low frequencies are used, because they travel further than high frequencies; horns from ships have been heard as far as fifteen kilometres (ten miles). [1] Traditionally, the lower the frequency, the larger the ship. The RMS Queen Mary, an ocean liner launched in 1934, had three horns based on 55Hz (corresponding to A1 ), a frequency chosen because it was low enough that the very loud sound of it would not be painful to the passengers. [2] Modern International Maritime Organization regulations specify that ships' horn frequencies be in the range 70–200Hz (corresponding to C ♯ 2-G 3) for vessels that are over 200m (660ft) in length. For vessels between 200 and 75m (660 and 250ft) the range is 130–350Hz and for vessels under 75m (250ft) it is 70–700Hz. [3] Horns can be used singly, but are often arranged in pairs to produce an interval consisting of two notes, sounded together; although this doubles the sound volume, the use of two differing frequencies is more perceptible to the human ear than two horns of the same frequency, particularly in an environment with a high ambient noise level. Typical frequencies of a pair of horns of this design are 500Hz and 405–420Hz (approximately B 4 and G ♯ 4, minor third).A klaxon is a type of an electromechanical horn or alerting device. Mainly used on cars, trains and ships, it produces an easily identifiable sound, often transcribed onomatopoeiacally in English as "awooga". Like most mechanical horns, it has largely been replaced by solid-state electronic alarms, though the memorable tone has persisted. Klaxon was originally a brand name. During the last ten years, some manufacturers have departed from the traditional car horn design altogether, but arguably the most significant recent development has arrived with the age of the electric vehicle. With EVs now being effectively silent, new legislation in some markets means manufacturers must design electric vehicle warning sounds which are played continuously when travelling at low speeds to warn pedestrians. Varying from artificial beeps and chimes, to drones and fake engine noises, the Acoustic Vehicle Alerting System (AVAS) could be considered as the most modern development in the history of car horns. The Moflash Company discontinued the Klaxet hooter in 2013, but continued to produce the A1 hooter, the only original Klaxon left in production.
