What causes a constant buzzing sound from a single car horn?

[CorbinAnn]

The reason for a buzzing sound in car audio is that the amplifier's input signal line uses shielded cable, and the cable's mesh layer must be grounded. The power wiring of the amplifier should be connected from back to front, and the power should not be connected at the input end. When wiring the amplifier, there should be no grounding phenomenon in the middle, as grounding is equivalent to creating eddy current crosstalk. Below are detailed instructions on the correct use of car horns: 1. Narrow sections: On narrow two-lane roads such as rural paths or mountain roads, overtaking often requires borrowing the opposite lane. In such cases, it is advisable to honk the horn before overtaking to alert the vehicle in front and avoid accidents. 2. Overtaking on curves: Honking the horn before entering a curve can alert vehicles in the opposite lane to avoid crossing the line. If you receive a horn signal from the opposite direction before a curve, it is recommended to respond with a honk. This way, both parties can be aware of oncoming vehicles, ensuring they stay within their own lanes and drive safely with peace of mind.
