Your car horn should be audible from around 200 to 400 feet away, depending on the specific design of the horn and the surrounding ambient noise levels. It's important for the horn to be loud enough to alert other drivers of your presence but not excessively loud to cause noise pollution.
An air horn has a small air compressor which generates a movement of air through the device at speed. When the user of the horn presses the button, the horn creates a noise.
In Britain, the horn of a car is commonly referred to as the "horn." However, drivers might also refer to it as "the klaxon," especially when talking about older vehicles or in a more colloquial context. The term "horn" is widely understood and used in everyday conversation.
A horn can be a musical instrument, a safety feature on a car, a protrusion on the head of an animal, a way to butt in on a conversation, or a new years noise maker.
one way that it has traditionally been done is to introduce voltage (12 volts) to a thin metal plate encased in a horn...that will amplify the noise the plates makes when it vibrates.
