In this study, we analyzed the image characteristics of vehicle type and the operating sound quality by jury testing the operating noise of the power seat slide adjuster for the vehicle. First, the operating noise for five test power seats was measured and adjectives for subjective sound quality evaluation were extracted through questionnaires. Next, the images according to vehicle type were examined using the extracted adjectives. Third, a subjective evaluation of sound quality was performed using a loud speaker. At this time, the sound quality and the sound image of the operating noise were extracted by examining the preference, adjective score using the semantic differential, and vehicle matching the sound source. Thus, it was possible to suggest sound quality characteristics of slide operating noise and improvements in sound quality according to vehicle type.
