Abstract
Recently, comfortable automobile running sounds are considered to be an added value to attract the attention of automobile users. This study, in order to develop an automobile running sound on which people can feel comfortable with their multiple sensations, an objective sound quality evaluation based on physiological information will be focused on. However, dispersion can occur in a measurement result because physiological information is not stable due to a difference of their internal thoughts or their physiological conditions. Therefore, the method to reduce the dispersion in the physiological evaluation result will be proposed by using the tasks that are helpful to regulate subjects’ conditions. In this paper, following three studies will be discussed; (1) consideration of the effective task to reduce the dispersion by objective evaluation, (2) construction of experimental condition using the driving simulator to evaluate car running sound in conditions similar to actual vehicle ,and (3) trial of an objective evaluation of car running sounds in simulated driving condition using the task
