Electronic Sound in Automobile and Sound Feeling

The electronic sound is used as one of the very common means of human-machine interface. Few investigations of how human feels to such the simple sounds noisy or comfortable, exist. The electronic sound must be designed by considering how or in what situation it is used. This research is aimed at investigating how human feels to a variety of electronic sound and describes the relation between human feeling and physical characteristics of sound. We investigated how physical parameters of sound effect to the human feeling via evaluation experiments. We found relations between the human auditory feeling and the physical characteristics of the sound. We showed a guideline of how to design a variety of electronic sound that satisfy the given human feeling specifications.
