Outline of Final Research Achievements

We have developed a prototype of a compact, power-saving, stand-alone mobile hypersonic system that integrates an ultrahigh frequency reproduction element, a circuit to drive the element, and a mobile player to play the contents. By comparing and analyzing several rainforest natural environmental sounds rich in ultrahigh frequencies, we developed ultrahigh-frequency contents suitable for this system and confirmed their effectiveness through evaluation experiments.
