Sensory Evaluation of Sound Quality for Vehicle Power Seat Slide Adjuster

Abstract

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.

Methodology for Sound Quality Analysis of Motors for Automotive Interior Parts through Subjective Evaluation

“…However, with the improvement of indoor quietness and quality of sensibility, noise generated from the driving mechanism of interior parts, such as power windows, panoramic sunroofs, and power seats, which were previously not an issue, is relatively highlighted. In particular, as the power seat for automobiles is being developed as a seat system with multiple functions (e.g., swivel, belt in seat, long rail slide, and wireless power transmission) as the level of autonomous vehicles develops along with electric vehicles [1][2][3][4], improvement of the noise of the driving mechanism in the interior is gaining significance [5].…”
