Abstract

When riding a motorbike with a helmet or driving a car, it is often experienced that the judgment of directions of alarm sounds like a horn and sirens of engine truck and ambulance car becomes difficult. This kind of auditory localization is seriously related to traffic safety. In this study, therefore, the effects of covering the driver' s head with a helmet and sound transmission into a car on the auditory localization for traffic alarm sounds were examined by laboratory tests. To simulate a 3-dimensional sound field, the 6-channel recordingreproduction technique was applied and the incident direction of the test sounds was varied in twelve horizontal directions.
