| Outline of Final Research Achievements |
In this study, our goal is to achieve three-dimensional sound field reproduction using small and flexible system. To achieve it, we propose three-dimensional sound field reproduction with a parametric loudspeaker. Parametric loudspeaker can achieve sharper directivity using ultrasound. At first, listener localization is achieved by the acoustic distance measurement (ADM) method based on interference. Second, the acoustic imaging is achieved using the ADM method with a loudspeaker and a microphone-array to search listener’s ears. Finally, the proposed method can reproduce the three-dimensional sound field by presenting sound information with head-related transfer function for each ear using audio-spot with the parametric loudspeaker.
