Sonoliards: Rendering Audible Sound Spots by Reflecting the Ultrasound Beams

We propose a highly versatile and interactive system that can simulate and generate arbitrary sound field at a specific place. There has been considerable research on sound field simulation in the context of sound field design. However, there were no dynamic applications adaptable to various environments. Our system can apply to various environments using motion capture and 3D model data of the specific room by inputting the people’s position and room. Geometric information and simulate the reflection on walls and ceilings with sound propagation method and deliver sound to a specific person by controlling parametric angle speaker in real time. In order to evaluate the performance of this proposed system, we explain the method of generating the dynamic sound field of our system and conducted 2 experiments: i) for analyzing human factors, ii)for express sound localization. Our system can apply to surround speaker for people who is moving, so we also conducted second experiment to to express sound localization control by controlling the direction of the parametric speaker.
