**3. Identification of emitting sound patterns in sequences**

In this section, as a first step towards developing the guidance system utilizing a sound sequence emitting a sound stimulus to induce people to exit, two experiments to test whether people can identify the sound sequence is described with reference to our previous research [6]. The actual evacuation routes include a variety of patterns, so the two sequence patterns of sounds, straight-line and right-angle patterns were evaluated in the following subsection.
