Outline of Final Research Achievements

Four kinds of technologies in acoustic information have been investigated for digital signage in order to supplement a sense of reality and multiple deep meanings, etc. in industry and tourism. They are 1) acoustic information by ultrasonic beams can be listened within 4 meters, 2) next acoustic information cannot be listened for privacy guard that separates two sound globes, 3) loud acoustic information (83.4dB-98.3dB in white noise) in an audible globe can be listened without noise, and 4) an audience can simultaneously acquires multiple information at the intersection of ultrasonic beams.
