A two-channel stethoscope system that records lung sounds was developed.The stethoscope system consisted of a pair of stethoscopes, namely two microphones each surrounded by chest piece, 2 channel digital voice recorder and sound analysis software. In a spontaneous pneumothorax patient, respiratory sound on the collapsed side was reduced, however the leaking sound was not detected clearly.On the completely collapsed side, heart or aortic sound were detected. In the bronchial fistula or pleural fistula after the lung surgery, transverse lines similar to wheeze recorded in bronchial asthma patient were detected on the sound spectrogram analyzed by analysis software. And additional wave on the sound spectrogram was detected on the collapsed side. This sound might be produced by inflating lung.

开发了一种记录肺部声音的两通道听诊器系统。听诊系统由一对听诊器组成，分别有两个麦克风，每个麦克风都被胸部包围，2通道数字配音录音机和声音分析软件。 在自发的气胸患者中，塌陷侧的呼吸声被降低，但是漏水的声音未清楚地检测到泄漏的声音。在完全塌陷的侧面，心脏或主动脉声音中。在肺部手术后的支气管瘘或胸膜瘘中，通过分析软件分析的声学光谱图检测到类似于支气管哮喘患者中记录的喘息的横向线。在折叠侧检测到声频谱图上的其他波。这种声音可能是通过充气肺产生的。
