Excessive amounts of daily stress threaten mental health and increase mental illness such as depression. And, it is important to learn how to know stress burden of individuals and coexist well with mental stress. We have therefore developed physiological signal sensors for measurement of heart and respiratory rate as common stress markers, and analyzed cardiovascular reaction and salivary coltisol reaction as typical physiological reaction. The present study has focused on body-sound comprised of sound generated by internal organs. We newly developed a prototype body-sound sensor consisting of stethoscopes, amplifier microphones and an IC recorder. We proposed measuring heart and respiratory rate simultaneously from body-sound at the neck using continuous wavelet transformation. We experimentally confirmed that heart and respiratory rate were determined by our proposal and ECG or respiratory waveform coincided sufficiently to be feasible. Also, we have conducted stress evaluation experiment including repeated subtraction task and mirror drawing task to measure cardiovascular and salivary coltisol reaction. We confirmed that heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure were significantly increased by the mental stress.

过多的日常压力会威胁心理健康，并增加抑郁症等精神疾病。而且，学习如何了解个人的压力负担并与精神压力良好共存也很重要。因此，我们开发了生理信号传感器，用于测量心脏和呼吸频率作为常见的应激标志物，并分析了心血管反应和唾液coltisol反应作为典型的生理反应。本研究的重点是由内部器官产生的声音组成的体音。我们新开发了一个原型的身体声音传感器组成的听诊器，放大器麦克风和IC记录器。我们提出了利用连续小波变换从颈部的体音同时测量心率和呼吸率。我们通过实验证实了我们的建议确定了心率和呼吸率，并且ECG或呼吸波形完全一致，这是可行的。此外，我们还进行了应激评估实验，包括重复减法任务和镜像任务，以测量心血管和唾液coltisol反应。我们证实，心率，收缩压，舒张压和平均动脉压显着增加的精神压力。
