This research investigated a method for providing the auditory information to drivers in active safety vehicles. Our first report clarified that it was difficult for elderly drivers to segregate the voice signal from background noise and acquire the multiple auditory items in a short time. Therefore the experiments were conducted to examine whether they could capture the voice information while listening to the radio news. As results, the radio listening hindered the information acquisition regardless of whether participants were listening to news in a careful or uncareful manner. It was also revealed that the female voices were easer to discriminate than the male voices.
