Honking a car horn is to bring forth the sound of a car horn close to its maximum audible level, to attract utmost attention.
Decrease.
As the moving car approaches the person in front of it, the pitch of the car horn will sound higher due to the Doppler effect. This occurs because the sound waves get compressed as the car moves closer, causing the frequency to increase and the pitch to sound higher.
Honk or honking sound.
As it has a higher frequency than a car horn.. Pitch depends upon frequency....
I think it's only to increase the sound of the horn to be able to here it in the loud traffic noise also.
Answer 1A car horn produces sound by using electrical energy to viabrate a diaphragm inside the horn which sets up pressure waves in the air, thus becoming sound when heard. The horn diaphragm's creation of sound waves is similar to the way a speaker diaphragm converts electrical pulses from an amplifier into sound, except that the horn is designed to produce only a single frequency of sound, whereas the speaker can produce many different frequencies.
You can replace the standard car horn with pretty much any horn you want. Given that many truck horns are powered by air, it would be difficult to duplicate in a car unless you can rig an air compressor.
It is important to know what is causing problems in a car. When the horn relay clicks, but the horn does not sound, it is not a fuse but more likely to be the cars clock spring.
Physically remove the horn from the car. Ground it to a good ground on the engine, or car body. Attach a lead to the positive ( + ) side of the battery, with the free end, touch the connection on the horn and it should blow( sound ).
