Abstract
To evaluate the sound quality of manual operation sounds of copy machines and laser printers, such as opening and closing front cover, drawing and loading paper trays, and locking and releasing hooks, the free description experiment using onomatopoeic representation was examined. The obtained onomatopoeic representations represent the acoustical properties such as the rubbed sounds with high energy in the high frequency region affect the sound quality of manual operation sounds. Furthermore, the subjective evaluation experiments of the product image were conducted to show the relationships between the product image and onomatopoeic features.
