Abstract:Acoustic zooming aims at increasing and decreasing the perceived distance of the sound-image by varying a zoom-parameter. Previously proposed superdirective acoustic zooming techniques focus on controlling the directivity-factor of the constructed beampattern by varying this zoom-parameter. As a result, these zooming techniques are only consistent in the case of (spherically) isotropic interferences. In practical situations however, often directional interferences (mainly coming from a single direction) are pr… 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.
