This paper presents an objective evaluation method for the perceived quality of car horn sound based on a psychoacoustic metric and a subjective test. A new psychoacoustic metric called the “spectrum decay (SD) slope” was developed to evaluate a luxury timbre in the sound quality of the horn sound. Eight synthetic sounds with a variety of SDS slope are designed. The synthetic sounds are subjectively evaluated by 41 subjects. A sound quality index for car horn sound is developed based on the correlation between the SD slope and subjective rating for synthetic sounds. The sound quality index is applied to the estimation of the sound quality of horn sounds of ten passenger cars measured inside the cars. The measured horn sounds are also evaluated subjectively by the same 41 subjects. The correlation between the estimated subjective rating and the subjective rating evaluated by the subjects is sufficient (R= 0.93, p <0.01) for the validation of the sound quality index.
