Development of Active Sound Masking System for Speech Privacy Protection

近年来，在小型诊所候诊室附近的口腔咨询、税务局窗口的纳税咨询、学校教室的课程咨询、临时摊位的法律的援助服务等开放空间中实现言语隐私受到重视。从这个角度出发，在这项研究中，我们提出了一个积极的声音掩蔽系统，并根据心理学实验的结果，所提出的系统的有效性进行了确认。

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 active sound masking system, and the effectiveness of the proposed system was confirmed based on the results of psychological experiments.
