Outline of Final Research Achievements

In this study, to clarify what the important acoustic features from sound direction in order to easily listen target sound. Then, we conducted listening tests using sound presentation system which can control acoustic features. In addition, the system which can help to listen target sound was develop and evaluate with listening test's result. These results suggest that the important acoustic features from sound direction are contribute to hearing aid development.
