Outline of Final Research Achievements

In recent years, importance has been attached to achieving speech privacy in open spaces such as for oral consultations near waiting rooms of small-scale clinics, tax-payment consultations at a taxation office window, course consultations in school classrooms, and legal aid services in temporary booths. From this viewpoint, in this study, we proposed an sound masking system based on acoustic space conditions, and the effectiveness of the proposed system was confirmed based on the results of psychological experiments.
