| Outline of Final Research Achievements |
This study was consisted of measurement of sound localization performance of listers in experimental rooms, and in-situ measurement of physical properties of acoustical environment. The relationship between both measurement results enabled to realize a measurement tool for sound localization performance of auditory guide signals in public spaces. Results of a measurement is presented on a screen of tablet PC with numerical values and graphical presentation of estimated sound localization from acoustical input to both ears of a listener. The presented result of the measurement tool is well correlated with sound localization of listener on horizontal plane but not well estimate on vertical plane. It was more difficult to obtain accurate sound localization of listeners on vertical plane than horizontal plane with visual attention measurement, which was used to confirm sound localization of listers with gaze measurement.
