Abstract (in Japanese) (See Japanese page) 
(in English) Several blind persons can perceive obstacles using the sense of hearing. If the sounds which are easy to perceive obstacles are used for Hand-Held sound generator, it is useful for efficient acquisition of obstacle perception ability. We made Hand-Held sound generator using white noise, and evaluated the relation of obstacle size and distance to the obstacle. As a result, we can perceive an obstacle which is near to us until 1.0m; however, we cannot perceive one which is far from us over 2.0m. To investigate whether or not the sound generator helps obstacle perception, we conducted a hearing experiment to focus on a scan and a direction of the sound generator. As a result, scanning the sound generator may improve obstacle perception ability.
