The sound quality of the machinery noise of laser printers was evaluated by a semantic differential method. The averaged rating values were applied to a principal component analysis. According to the relationships between factor scores on each factor and acoustical properties of the machinery noise, acoustical indices were proposed to predict subjective impression of the machinery noise. Furthermore, to evaluate the sound quality of manual operation sounds of copy machines, 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 features of sound quality and acoustical characteristics of operation sounds.
