Abstract (in Japanese) (See Japanese page) 
(in English) When a listener perceives the direction of a sound source in reflective sounds, the directional information of the first incoming sound plays a main role. Since the sound image is localized in the direction of the first incoming sound, this phenomenon is called the precedence effect. This research is aimed at building an escape-guiding system using the audio signal. This system utilizes precedence effect with suitable delay time for each speaker and gives emergency guidance. In this report, the generation of the precedence effect was investigated by the listening tests, in which the delay times were parameters. The listening tests were conducted using two or three speakers in a laboratory and four speakers in an actual environment. The obtained suitable delay times were compared and discussed in detail.
