论文摘要
身体声音提供了有关人体状态的丰富信息，并且在许多医疗应用中都可能有用。听觉是倾听身体声音的实践，已在呼吸道和心脏医学中使用了数百年来诊断或跟踪疾病进展。但是，迄今为止，它的使用仅限于临床和高度控制的环境。我们的工作解决了这一限制：我们设计了一个胸部安装的可穿戴设备，用于连续监测身体声音，以利用运行在设备的数据处理算法。我们专注于检测心脏声音以进行心率监测。为了提高对环境噪声和运动伪像的鲁棒性，我们的设备使用一种算法将收集的音频明确将所收集的音频分为心脏周期的阶段。我们与9位用户的试点研究表明，可以获得与商业心率监测器竞争的心率估计值，并具有足够低的功耗以持续使用。
Body sounds provide rich information about the state of the human body and can be useful in many medical applications. Auscultation, the practice of listening to body sounds, has been used for centuries in respiratory and cardiac medicine to diagnose or track disease progression. To date, however, its use has been confined to clinical and highly controlled settings. Our work addresses this limitation: we devise a chest-mounted wearable for continuous monitoring of body sounds, that leverages data processing algorithms that run on-device. We concentrate on the detection of heart sounds to perform heart rate monitoring. To improve robustness to ambient noise and motion artefacts, our device uses an algorithm that explicitly segments the collected audio into the phases of the cardiac cycle. Our pilot study with 9 users demonstrates that it is possible to obtain heart rate estimates that are competitive with commercial heart rate monitors, with low enough power consumption for continuous use.
