Development of acoustic design considering both speech intelligibility and speech privacy in medical facilities

在医疗设施的声学设计中，不仅要考虑语音的可理解性，还要考虑语音的隐私性。声学测量表明，通过实际的吸收处理，可以很容易地改善某医院房间的可听性问题。同时，在听力测试的基础上，提出了一种根据房间的物理参数预测信息泄漏程度的方法。此外，还定量地阐明了词语可理解性与咨询室%-不满意度之间的关系

Not only speech intelligibility but also speech privacy should be considered in acoustic design in medical facilities. Acoustic measurements indicated that an example of the room with intelligibility problem in a hospital can be easily improved by practical absorption treatment. Meanwhile, a method for predicting word intelligibility, which indicates the degree of information leakages, from physical parameters of rooms was suggested on the basis of listening tests. Furthermore, the relationship between word intelligibility and%-dissatisfaction for consulting rooms was clarified quantitatively
