Some of congenital blind persons recognize obstacles and surrounding environment by sounds. This ability is called obstacle sense. But it is relatively difficult for the blind who lost their sight posteriori to acquire this ability because they don't have long acoustic training. This research intended them and examined the sounds which are easy to recognize obstacles. We carried out the experiment of pointing to the opened direction with white cane or synthetic sound on some sighted people wearing an eye mask. We found accuracy of the angle of pointing to the opened direction and the time from starting to sound. Additionally we carried out the experiment of walking against a wall with white cane or synthetic sound on some sighted people. Then we measured the distance they felt to be or run into something while walking. Finally, we found the relationship between these sounds and easiness to recognized obstacles.
