Auditory signals in automobiles function important roles such as danger alarm, operation feedback, malfunction warning, etc. However, there were not enough studies on the design of auditory signals in automobiles. In the present study, the relationship between the acoustic properties and auditory impression of reverse gear car alarm-sounds were examined. Fundamental frequency of the appropriate sounds for reverse gear car-alarm is 1k to 2kHz. Their spectral centroid is lower than 3.5kHz. Reverse gear alarm-sounds are intermittent sounds. The duration of sound and inter onset interval of the appropriate alarm is 500 to 700 ms. We obtained systematic knowledge to design appropriate and comfortable sounds for reverse gear car alarm.
