This study presents the design, development and implementation of a simple low-cost method of phonocardiography signal detection. Human heart and lung signals are detected by using a simple microphone through a personal computer; the signals are recorded and analysed using LabView software. Amplitude and frequency analyses are carried out for various phonocardiography pathological cases. Methods for automatic classification of normal and abnormal heart sounds, murmurs and lung sounds are presented. Various cases of heart and lung sound measurement are recorded and analysed. The measurements can be saved for further analysis. The method in this study can be used by doctors as a detection tool aid and may be useful for teaching purposes at medical and nursing schools.
本研究介绍了一种简单低成本的心音图信号检测方法的设计、开发和实施。通过个人电脑使用一个简单的麦克风来检测人体心肺信号；使用LabView软件对信号进行记录和分析。对各种心音图病理病例进行了幅度和频率分析。提出了正常和异常心音、杂音及肺音的自动分类方法。记录并分析了各种心肺音测量病例。测量结果可以保存以便进一步分析。本研究中的方法可供医生用作检测辅助工具，可能对医学院和护理学校的教学也有用处。
