Abstract:Recently, technologies for reproducing a 3-D sound field are required for providing highly realistic sensations. We previously proposed a system with multiple parametric loudspeakers that have a higher directivity by using ultrasound to reproduce an audible sound in a particular area. These loudspeakers can design sound images on walls, ceilings, and floors by reflecting an emitted sound, and thus, the proposed system can easily present incoming sound from various directions. However, it is difficult to mainta… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
