Abstract

Sensory evaluation tests were conducted to clarify differences in Japanese, German, and American perception of car interior sounds. The results of statistical analysis indicate that perceptions can be classified under two major categories: Luxury and Sporty, and that car interior sounds can be represented by these two axes. Further analysis of the sensory evaluation tests showed that sound preferences could also be described by these same categories. It is seen that even people with different preferences could have the same perception of luxury and sporty sounds. By country, a sporty acceleration sound was most preferred by Japanese, American, and German subjects, respectively. An application was developed that is capable of computing objective values for luxury and sporty sounds.
