Sounds from electric appliances, such as vacuum cleaners and copiers, cannot be disregarded in the development of quality products. It is not easy to obtain pleasant mechanical sounds, however, when electric appliances are designed according to the conventional trial-and-error method.
Toshiba has developed a design methodology to obtain pleasant mechanical sounds and applied it to products. This methodology incorporates two evaluation methods. One is a sensory evaluation method employing the semantic differential (SD) technique, which determines psychological metrics to measure the level of pleasant sound. The other is a physical evaluation method to which Zwicker’s sound quality metrics analysis can be applied, which determines physical metrics to measure the level of pleasant sound. Zwicker’s analysis determines four metrics of sound quality: loudness, sharpness, roughness, and fluctuation strength. Using these four metrics, physical metrics are defined statistically. Finally, pleasant sound is expressed substantially in terms of psychological metrics. Translation from psychological metrics to physical metrics is therefore required.
