Abstract

This study presents a multi-audio guidance system for a guide robot. The system is outfitted with parametric speakers constructed from ultrasonic array transmitters. When the two speakers are closely spaced, their sounds and their ultrasonic waves interact. To investigate these phenomena, the present study demonstrates the system and evaluates its characteristics. Good hearing conditions were obtained when the two parametric speakers were rotated more than 15ø from the "straight-ahead" direction. The audience should stand within ñ10 ø in front of each speaker. This system could simultaneously guide many persons of different age, nationality, sex, and other demographics with different guide contents.
