Car horns have the function of warning road users of potential danger. At the same time, car horn manufacturers want to adjust the horns to match their car category and brand identity. Therefore, designing the sound of car horns requires special expertise.

Vehicle horns must not only meet legal regulations regarding sound level, but also meet various demands regarding sound quality.

The sound quality of the horn is important in two ways. The first is that it has to be loud. The other is when a driver hears this sound. Therefore, the external sound originating from the horn is related to the loudness. The sound emitted from the horn should be loud and this sound depends on the design of the horn. The sound originating from the horn depends on two factors.

The first element is the airway inside the horn. The other is related to the structural feature of the horn. The sound quality of the horn heard inside a car relates to a combination of sounds transmitted from both paths. To evaluate sound quality inside the car, an objective method of evaluating sound quality in both ways is needed.

Advanced laboratories employ a test method that objectively evaluates the sound quality of a horn inside a car, based on spectrum analysis and octave analysis.

Horns with QLabel quality labels undergo such tests and are proof of high performance and quality for drivers.
