Objective: This study aims to identify how psychoacoustic characteristics of vehicle exhaust sound affect subjective impression and satisfaction. Furthermore, we studied relative importance of each physical element. Background: Nowadays, companies endeavor to construct appropriate product sound to gain competitive advantage, but few studies have focused on the relationship of psychoacoustic characteristics, impression and users’ satisfaction. For Korean car companies, since engine exhaust sound is crucial to users’ satisfaction, they need to understand physical characteristics of engine sound and how they affect users’ affective factors. Method: We analyzed impression of nine engine exhaust sounds and how they affect users’ satisfaction. Subjective impressions are composed of sixteen pairwise adjectives using semantic differential scale. They are categorized by factor analysis, and each three dimension significantly affected user’s satisfaction. Results: Impression evaluation is affected by loudness and sharpness, but not by fluctuation strength and roughness. Sixteen adjectives are categorized by three dimensions and psychoacoustic attributes showed different relative importance to each dimension. They eventually affected satisfaction significantly. Conclusion: Loudness and sharpness of engine exhaust sound affected subjective impression significantly, but they did not directly affect user’s satisfaction. However, since impression evaluation shows strong relationship with affective reaction, it shows sound metrics affect user’s emotion indirectly. Application: This study shows loudness and sharpness of engine exhaust sound affect users evaluating impressions. It implies car companies can design physical dimensions considering user’s affective evaluations.
