Abstract
In auditory signal design for vehicle on-board systems, it is possible to freely select the combinations of tone characters, harmony/chords or melodies to provide the signal with the desired function. Higher harmonics, harmony and sustaining time are discussed as the tone characteristics of information sound in this study. The sensibility/Kansei values of these factors were subjectively evaluated by 135 participants with a wide range of ages. The adjectives were classified into two stages that related to “physical property” and “sensibility/Kansei value”. The results give a clearer understanding of the relation/structure between the “physical property” of the information sound and the “sensibility/Kansei value”, and clarified guidelines for how to design tone characteristics to realize the sensibility/Kansei targets.
